Assessing the effects of fuel energy consumption, foreign direct investment and GDP on CO2 emission: New data science evidence from Europe & Central Asia

Documentation matters: human-centered ai system to assist data science code documentation in computational notebooks.

Computational notebooks allow data scientists to express their ideas through a combination of code and documentation. However, data scientists often pay attention only to the code, and neglect creating or updating their documentation during quick iterations. Inspired by human documentation practices learned from 80 highly-voted Kaggle notebooks, we design and implement Themisto, an automated documentation generation system to explore how human-centered AI systems can support human data scientists in the machine learning code documentation scenario. Themisto facilitates the creation of documentation via three approaches: a deep-learning-based approach to generate documentation for source code, a query-based approach to retrieve online API documentation for source code, and a user prompt approach to nudge users to write documentation. We evaluated Themisto in a within-subjects experiment with 24 data science practitioners, and found that automated documentation generation techniques reduced the time for writing documentation, reminded participants to document code they would have ignored, and improved participants’ satisfaction with their computational notebook.

Data science in the business environment: Insight management for an Executive MBA

Adventures in financial data science, gecoagent: a conversational agent for empowering genomic data extraction and analysis.

With the availability of reliable and low-cost DNA sequencing, human genomics is relevant to a growing number of end-users, including biologists and clinicians. Typical interactions require applying comparative data analysis to huge repositories of genomic information for building new knowledge, taking advantage of the latest findings in applied genomics for healthcare. Powerful technology for data extraction and analysis is available, but broad use of the technology is hampered by the complexity of accessing such methods and tools. This work presents GeCoAgent, a big-data service for clinicians and biologists. GeCoAgent uses a dialogic interface, animated by a chatbot, for supporting the end-users’ interaction with computational tools accompanied by multi-modal support. While the dialogue progresses, the user is accompanied in extracting the relevant data from repositories and then performing data analysis, which often requires the use of statistical methods or machine learning. Results are returned using simple representations (spreadsheets and graphics), while at the end of a session the dialogue is summarized in textual format. The innovation presented in this article is concerned with not only the delivery of a new tool but also our novel approach to conversational technologies, potentially extensible to other healthcare domains or to general data science.

Differentially Private Medical Texts Generation Using Generative Neural Networks

Technological advancements in data science have offered us affordable storage and efficient algorithms to query a large volume of data. Our health records are a significant part of this data, which is pivotal for healthcare providers and can be utilized in our well-being. The clinical note in electronic health records is one such category that collects a patient’s complete medical information during different timesteps of patient care available in the form of free-texts. Thus, these unstructured textual notes contain events from a patient’s admission to discharge, which can prove to be significant for future medical decisions. However, since these texts also contain sensitive information about the patient and the attending medical professionals, such notes cannot be shared publicly. This privacy issue has thwarted timely discoveries on this plethora of untapped information. Therefore, in this work, we intend to generate synthetic medical texts from a private or sanitized (de-identified) clinical text corpus and analyze their utility rigorously in different metrics and levels. Experimental results promote the applicability of our generated data as it achieves more than 80\% accuracy in different pragmatic classification problems and matches (or outperforms) the original text data.

Information Resilience: the nexus of responsible and agile approaches to information use

AbstractThe appetite for effective use of information assets has been steadily rising in both public and private sector organisations. However, whether the information is used for social good or commercial gain, there is a growing recognition of the complex socio-technical challenges associated with balancing the diverse demands of regulatory compliance and data privacy, social expectations and ethical use, business process agility and value creation, and scarcity of data science talent. In this vision paper, we present a series of case studies that highlight these interconnected challenges, across a range of application areas. We use the insights from the case studies to introduce Information Resilience, as a scaffold within which the competing requirements of responsible and agile approaches to information use can be positioned. The aim of this paper is to develop and present a manifesto for Information Resilience that can serve as a reference for future research and development in relevant areas of responsible data management.

qEEG Analysis in the Diagnosis of Alzheimers Disease; a Comparison of Functional Connectivity and Spectral Analysis

Alzheimers disease (AD) is a brain disorder that is mainly characterized by a progressive degeneration of neurons in the brain, causing a decline in cognitive abilities and difficulties in engaging in day-to-day activities. This study compares an FFT-based spectral analysis against a functional connectivity analysis based on phase synchronization, for finding known differences between AD patients and Healthy Control (HC) subjects. Both of these quantitative analysis methods were applied on a dataset comprising bipolar EEG montages values from 20 diagnosed AD patients and 20 age-matched HC subjects. Additionally, an attempt was made to localize the identified AD-induced brain activity effects in AD patients. The obtained results showed the advantage of the functional connectivity analysis method compared to a simple spectral analysis. Specifically, while spectral analysis could not find any significant differences between the AD and HC groups, the functional connectivity analysis showed statistically higher synchronization levels in the AD group in the lower frequency bands (delta and theta), suggesting that the AD patients brains are in a phase-locked state. Further comparison of functional connectivity between the homotopic regions confirmed that the traits of AD were localized in the centro-parietal and centro-temporal areas in the theta frequency band (4-8 Hz). The contribution of this study is that it applies a neural metric for Alzheimers detection from a data science perspective rather than from a neuroscience one. The study shows that the combination of bipolar derivations with phase synchronization yields similar results to comparable studies employing alternative analysis methods.

Big Data Analytics for Long-Term Meteorological Observations at Hanford Site

A growing number of physical objects with embedded sensors with typically high volume and frequently updated data sets has accentuated the need to develop methodologies to extract useful information from big data for supporting decision making. This study applies a suite of data analytics and core principles of data science to characterize near real-time meteorological data with a focus on extreme weather events. To highlight the applicability of this work and make it more accessible from a risk management perspective, a foundation for a software platform with an intuitive Graphical User Interface (GUI) was developed to access and analyze data from a decommissioned nuclear production complex operated by the U.S. Department of Energy (DOE, Richland, USA). Exploratory data analysis (EDA), involving classical non-parametric statistics, and machine learning (ML) techniques, were used to develop statistical summaries and learn characteristic features of key weather patterns and signatures. The new approach and GUI provide key insights into using big data and ML to assist site operation related to safety management strategies for extreme weather events. Specifically, this work offers a practical guide to analyzing long-term meteorological data and highlights the integration of ML and classical statistics to applied risk and decision science.

Concurrency and Computation: Practice and Experience

ArXiv, 2021

Data engineering is one of the fastest-growing fields within machine learning (ML). As ML becomes more common, the appetite for data grows more ravenous. But ML requires more data than individual teams of data engineers can readily produce, which presents a severe challenge to ML deployment at scale. Much like the software-engineering revolution, where mass adoption of open-source software replaced the closed, in-house development model for infrastructure code, there is a growing need to enable rapid development and open contribution to massive machine learning data sets. This article shows that open-source data sets are the rocket fuel for research and innovation at even some of the largest AI organizations. Our analysis of nearly 2000 research publications from Facebook, Google and Microsoft over the past five years shows the widespread use and adoption of open data sets. Open data sets that are easily accessible to the public are vital to accelerate ML innovation for everyone. Bu...

Harvard business review, 2012

Back in the 1990s, computer engineer and Wall Street "quant" were the hot occupations in business. Today data scientists are the hires firms are competing to make. As companies wrestle with unprecedented volumes and types of information, demand for these experts has raced well ahead of supply. Indeed, Greylock Partners, the VC firm that backed Facebook and LinkedIn, is so worried about the shortage of data scientists that it has a recruiting team dedicated to channeling them to the businesses in its portfolio. Data scientists are the key to realizing the opportunities presented by big data. They bring structure to it, find compelling patterns in it, and advise executives on the implications for products, processes, and decisions. They find the story buried in the data and communicate it. And they don't just deliver reports: They get at the questions at the heart of problems and devise creative approaches to them. One data scientist who was studying a fraud problem, for...

Synthetic Data and Social Science Research: Accuracy Assessments and Practical Considerations from the SIPP Synthetic Beta

Synthetic microdata – data retaining the structure of original microdata while replacing original values with modeled values for the sake of privacy – presents an opportunity to increase access to useful microdata for data users while meeting the privacy and confidentiality requirements for data providers. Synthetic data could be sufficient for many purposes, but lingering accuracy concerns could be addressed with a validation system through which the data providers run the external researcher’s code on the internal data and share cleared output with the researcher. The U.S. Census Bureau has experience running such systems. In this chapter, we first describe the role of synthetic data within a tiered data access system and the importance of synthetic data accuracy in achieving a viable synthetic data product. Next, we review results from a recent set of empirical analyses we conducted to assess accuracy in the Survey of Income & Program Participation (SIPP) Synthetic Beta (SSB), a Census Bureau product that made linked survey-administrative data publicly available. Given this analysis and our experience working on the SSB project, we conclude with thoughts and questions regarding future implementations of synthetic data with validation.

This chapter is based in part on our presentation and paper from the 2023 NBER conference on Data Privacy Protection and the Conduct of Applied Research: Methods, Approaches and their Consequences. We thank the organizers and attendees for their feedback and discussion. We would also like to thank Gary Benedetto and Caleb Floyd for their comments on this chapter.

To describe the use of bibliometrics in nursing and assess their contribution to research and practice.

A content analysis was conducted of topics, data sources and applications of bibliometrics in nursing research articles.

The study universe included 129 bibliometric articles on nursing retrieved from Scopus. A content analysis was performed to identify the purposes and topics of the articles, the sources employed to collect the data, the time frames covered, the amounts of records surveyed, and the features of the nursing literature analysed in bibliometric papers.

Nursing bibliometric research revolves around six key areas: global descriptions of the nursing literature, literature on specific nursing research topics, nursing education, nursing profession, nursing research using a certain framework or method, and nursing literature published in a country or region. Studies rely on three types of sources to retrieve the surveyed literature: bibliographic databases, sets of disciplinary journals and samples of documents. Bibliometrics can be employed to advance nursing research (identification of research gaps, establishment of research agendas, assessment of methodological approaches, etc.) and practice (identification of professional competences, categorisation of professional tasks, recognition of educational improvements, etc.), suggesting new avenues for researchers who aim to conduct further bibliometric research in the field. Further research is needed to assess the coverage of the nursing literature by new bibliographic data sources and to explore unaddressed topics such as gender imbalance in authorship.

1. INTRODUCTION

Bibliometrics consists of the quantitative analysis of scholarly publications. It can be used to track the growth of a particular area of research over time and to analyse literature features such as authorship, collaboration patterns or identification of core journals in a discipline. Bibliometric analysis is often used to assess the research output of individuals, institutions and countries based on citation analysis. In addition, bibliometric studies can be useful to unveil research gaps in a field, pinpoint conflicting findings, disclose underexplored areas or reveal research biases such as the presence of overrepresented or underrepresented populations. Overall, bibliometric studies provide valuable insights into the patterns and trends of scholarly communication and research, and can be used to inform research policy, funding decisions and strategic planning (Thompson & Walker,  2015 ).

Cant et al. ( 2022 ) recently described bibliometrics as “an emerging science in nursing.” However, the use of bibliometrics to describe and assess the nursing literature has bloomed over the past two decades. Within this context, it is crucial to perform empirical assessments of the use of bibliometrics in nursing to identify how bibliometrics can improve our understanding of the field and to provide a solid foundation for researchers who wish to conduct further bibliometric studies in the discipline.

The contribution of this paper is twofold. First, it describes and assess the use of bibliometrics in nursing research literature. The purpose is to ascertain how bibliometric studies contribute to advance theory and practice in nursing research, identifying the purposes and topics of bibliometric articles in nursing, the sources employed to collect the data, the time frames covered, the amounts of records surveyed, and the features of the nursing literature analysed in bibliometric papers. Second, it offers guidelines to help nursing scholars to conduct bibliometric studies in the field by using the appropriate techniques in each instance according to their purpose. In short, we aim to help researchers understand bibliometrics and its usefulness to improve our understanding of nursing science and how to use bibliometric techniques meaningfully and rigorously in the discipline.

1.1. Background

Bibliometrics aims to describe and map the scientific knowledge in a discipline by making sense of large volumes of bibliographic data. It can be useful to obtain an overview of a discipline, identify knowledge gaps and derive novel ideas for investigation (Donthu et al.,  2021 , p. 285). Bibliometrics encompass two categories of analysis: performance analysis and science mapping. The first examines the participation of research contributors (authors, institutions, journals, etc.) to a field, including publication and citation analysis. Science mapping focuses on the relationships between research contributors making use of techniques such as co‐authorship, co‐citations or co‐word analysis. The combination of both approaches is useful to describe the intellectual structure of a research field (Mukherjee et al.,  2022 ).

In contrast to systematic reviews and meta‐analysis, bibliometric studies summarize the intellectual structure of a field by analysing the relationships between different research contributors. Rather than narrative synthesis of the content of individual articles based on manual analyses, bibliometric reviews provide quantitative measures and visualizations of large samples of papers that provide insights into the structure and evolution of the scholarly literature within a particular field.

The increasing interest in bibliometric studies within the health sciences has prompted the development of two recent sets of guidelines aimed at enhancing the reporting quality of such studies. Koo and Lin ( 2023 ) introduced the Preferred Reporting Items for Bibliometric Analysis (PRIBA) guidelines, comprising 25 items adapted from the PRISMA framework. Through an evaluation against the top 100 bibliometric studies in health and medicine from 2019 to 2021, these guidelines underscored the pressing need for improved reporting standards in bibliometric research. In parallel, Montazeri et al. ( 2023 ) formulated the Guideline for Reporting Bibliometric Reviews of the Biomedical Literature (BIBLIO), encompassing 20 items derived from a literature review and consensus among a panel of experts.

Few studies have discussed so far the usefulness of bibliometrics to improve our understanding of nursing science. In one of the first conceptual papers on the topic, Smith and Hazelton ( 2008 ) provided an overview of citation‐based research in nursing to map the core journals in the field and assess nursing research. Subsequently, Smith and Hazelton ( 2011 ) stressed their support for the use of bibliometrics and suggested that it should be included in nursing curricula. Later, Smith and Watson ( 2016 ) stated that bibliometric competencies should be expanded to altmetrics and social media.

Using a hands‐on approach, Alfonzo et al. ( 2014 ) outlined the basics of bibliometrics, the main steps in conducting a bibliometric study, features of bibliometric software and an example of applications with a small corpus in nursing research. In a similar fashion, Davidson et al. ( 2014 ) summarized the strengths and limitations of bibliometrics for mapping and assessing research performance in nursing, including webometric indicators such as the number of downloads or Twitter mentions.

Kokol and Vošner ( 2018 ) conducted the most extensive analysis of the application of bibliometrics in nursing to date. They analysed the historical roots of bibliometrics in nursing, the most productive countries, institutions and journals, and the most prolific themes in the application of bibliometrics in nursing. Their results showed a positive trend in literature production spread through all continents. Thematic analysis showed that applications of bibliometrics in nursing included descriptive analysis, research evaluation, content analysis, citation analysis and trend analysis.

In this study, we aim to provide additional insights of how bibliometrics is being used in nursing research. The purpose is to describe and assess the current state of bibliometrics in the field and to provide a solid basis for researchers who aim to conduct further bibliometric research in the discipline. The study is underpinned by the following research questions:

• What are the topics of nursing bibliometric studies?
• Which data sources, time frames and document populations are employed in nursing bibliometric research?
• What bibliometric approaches are used to analyse nursing science?
• What are the contributions of bibliometric studies to advance theory and practice in nursing research?

2.1. Design

A content analysis of nursing bibliometric papers was conducted to identify the purposes and topics of the studies, the sources employed to gather the data, and the features of the literature analysed in the papers.

2.2. Data collection

On 10 February 2023, we retrieved from Scopus the articles published up to 2022 that included the terms “bibliomet*” and “nurs*” in the title of the document. The search was not limited by document type, language or any other criteria.

We retrieved 143 records. Since the purpose of the study was to analyse the practical applications of bibliometrics in nursing, five conceptual papers on the topic were removed from the analysis. Nine additional papers were removed because: (a) they were in Chinese (four records) or German (one record), languages that we do not understand; (b) they were not available online in full text (three records); or (c) they did not offer original data, but a comment on another bibliometric study that was already included in the sample (one record). In the end, 129 articles were analysed.

2.3. Data analysis

The full text of the 129 articles was downloaded. Each article was screened to collect information on the aim of the study, the data sources employed and the analysis conducted.

The articles had been published over the course of two decades, from 2001 to 2022, with a clear growing trend: 64 articles (50%) had been published in the last 3 years considered, from 2020 to 2022. The articles had been published in 62 journals, although five sources concentrated 29% of the literature, each publishing more than five nursing bibliometric studies: Journal of Advanced Nursing (12 articles), International Journal of Nursing Practice (7), Journal of Nursing Management (7), Journal of Nursing Scholarship (6) and Texto e Contexto Enfermagem (6).

2.4. Data availability

3.1. topics of nursing bibliometric research.

Nursing bibliometric research can be broadly classified into six categories (Figure  1 ). First, 26 studies (20%) aimed to describe the global landscape of nursing scholarly literature. Second, 41 studies (32%) took a narrower approach to focus on the literature on a specific nursing research topic. Third, 23 studies (18%) analysed the literature on nursing education and training. Fourth, 20 studies (16%) explored the literature on the nursing profession, i.e., the workforce, workplace and working conditions. Fifth, 7 studies (5%) dealt with the features of nursing research that used a certain theoretical framework or research method. Finally, 12 studies (9%) analysed the nursing scholarly output published in a particular country or region. Some of the studies classified in the first five categories also had a geographic focus (e.g. a bibliometric analysis of the literature on a nursing topic published in a particular country). For the purposes of this paper, we classified these articles in the first five categories rather than in the sixth.

Topics of nursing bibliometric research.

3.1.1. Bibliometric studies on global nursing literature

The studies that took a broader approach aimed to provide an overview of nursing scholarly literature published in a certain time frame. For instance, Wang et al. [109] performed a global assessment of nursing research indexed in the Web of Science from 2009 to 2020. The results showed a positive publication trend of nursing papers, although restrained by low research funding, regionally centred research activity and limited international collaboration in developing regions.

Instead of searching a database to retrieve the literature in the field, some nursing bibliometric studies focused on the outputs published in a set of disciplinary journals. For example, Giménez‐Espert and Prado‐Gascó [39] analysed the outputs published between 2012 and 2017 in the six most reputable nursing journals according to their impact factor. Their results allowed an assessment of the state of nursing research by revealing the most popular authors, institutions and topics.

Alternatively, some studies focused on the bibliometric indicators of disciplinary journals. Thus, Smith [97] performed a longitudinal analysis of the evolution between 1977 and 2008 of seven nursing journals, especially their impact factors, which showed a sustained increase in the number of citations received. Similarly, Avena and Barbosa [5] compared bibliometric indicators provided by six databases for a set of seven Brazilian and seven international nursing journals between 2012 and 2014.

Finally, several case studies focused on particular nursing journals. The literature included studies on the Brazilian nursing journal Referência [88], the Journal of Advanced Nursing [121], the International Journal of Nursing Studies [50], The Canadian Nurse [71], the Philippine Journal of Nursing [106], the Journal for Nurse Practitioners [108] and the Journal of Nursing Management [118].

3.1.2. Bibliometric studies on specific nursing research topics

Most nursing bibliometric studies analysed the literature on a particular issue. The range of nursing research topics explored included artificial intelligence in nursing [94], cardiovascular nursing [15], cirrhosis nursing [42], COVID‐19 nursing [22; 84; 123], disaster nursing [76; 125], family nursing [46], genomic nursing [113], geriatric and gerontologic nursing [38; 79], HIV/AIDS nursing [29], intensive and coronary care nursing [67], mental health nursing [61], military nursing [25], multiple sclerosis nursing [119], nursing and ageing [90], nursing caregiving [33], oncologic nursing [124] and palliative care nursing [37].

In addition to bibliometric studies designed to quantify the literature on a particular topic, some studies employed bibliometrics to explore other features of the nursing literature. This suggests that there are additional applications of bibliometrics in nursing. Some bibliometric studies described the literature on research utilization in nursing [35; 93]. Another study used bibliometrics to measure the use in the literature of five nursing terminology sets [4]. Yet another approach consisted of exploring the comprehensiveness of systematic reviews in four guidelines for preventing in‐patient falls by comparing their references lists with all the available literature [21].

3.1.3. Bibliometric studies on nursing education and training

Papers classified in this category revolved around two main issues: nurses' competences and training strategies to improve nurses' education. Blažun Vošner, Kokol and Vošner [14] analysed the nursing competences research literature indexed in Scopus between 1981 and 2012. Su, Hwang and Chang [99] analysed nursing core competencies research indexed in the Web of Science between 1997 and 2022. Specific studies focused on the literature on certain competences of nurses, such as clinical reasoning [44], informatics [13; 57; 58; 62; 64; 65] and leadership [53; 81].

Regarding bibliometric studies on training strategies, some papers focused on the use of expressions of art in nursing education and care [36], robots [91], simulation [17; 111] or virtual simulation [18; 122].

3.1.4. Bibliometric studies on the nursing profession

Another topic of interest for nursing bibliometric research was literature on the workforce of nurses, the workplace and working conditions. Focusing on nursing professional practice, we found bibliometric studies on nursing advocacy [10], dignity care [66], patient satisfaction [100], nurse residency programmes [31], nurse rounding [49] or the use of robots to assist nursing care [19].

Other bibliometric studies focused on nurses' working conditions. They explored literature on the burnout syndrome among nurses [28; 32; 72], conflicts in nursing [53], job insecurity [89], nursing as a career [12], nurses' turnover [70], nurses' wellbeing [51], workplace bullying [68] and workplace incivility [103].

3.1.5. Bibliometric studies on nursing literature using a particular framework or research method

Some bibliometric papers focused on nursing literature that used a particular theoretical framework, research methodology or data collection technique. This category included bibliometric papers on nursing studies using action research [74], grounded theory [60], phenomenological approaches [75], qualitative methods [8; 77] and social representation theory [26].

3.1.6. Bibliometric studies on nursing literature in a geographic area

Finally, some bibliometric studies focused on the nursing literature published in a particular country or region. There were studies on nursing research in the Arab region [27], Australia [112], China [86], Colombia [16; 41], Spain [85], Taiwan [47] and Turkey [34]. Although most of these papers used a case study approach, which focused on the literature published in a single country, one study [104] compared nursing research published in six mainly English‐speaking nations (Australia, Canada, Ireland, New Zealand, the United Kingdom and the United States). Another international study [59] correlated nursing literature production with country and health determinants, including life expectancy, gross domestic product, human development factor and gross national income.

3.2. Data sources in nursing bibliometric research

Nursing bibliometric studies relied on three types of sources to retrieve the surveyed literature. First, 95 studies (74%) analysed the literature retrieved through one or several bibliographic databases. Second, 21 studies (16%) focused on articles published in a set of disciplinary journals. Third, 13 studies (10%) surveyed documents that shared a particular feature, such as having been selected by a group of experts or being a particular type of document, usually a dissertation or theses.

The three approaches were not mutually exclusive. Thus, a study analysing the literature published in a set of journals could rely on a bibliographic database to retrieve the records employed in the analysis. For the purposes of this paper, we classified these articles as being based on a set of journals rather than on a database.

3.2.1. Literature retrieved from bibliographic databases

The most common approach to data collection in nursing bibliometric studies was to retrieve the literature from one or several databases. Up to 39 sources were mentioned in the articles, with several studies combining two or more sources. The databases employed most frequently were the Web of Science (49 articles), Scopus (23), MEDLINE/PubMed (23) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 11).

In addition to their prestige, the preference for Web of Science and Scopus is explained by the fact that they are citation indexes, i.e., they list the references cited in the articles that they cover. This allows data to be obtained on the references cited by an article and the citations it receives. These data are not available for other databases, which prevents citation analysis, unless data from several sources is compiled. For instance, in a bibliometric study on robotics in nursing, Carter‐Templeton et al. [19] used CINAHL to identify the literature. Afterwards, citation counts were collected via Google Scholar, Scopus and the Web of Science. Similarly, in their article on distinct nursing research, Nicoll et al. [82] asked journal editors to identify relevant articles and the author then collected citations to these articles from Scopus.

The combination of several databases in a single study allows researchers to assess their comprehensiveness. For instance, Scott et al. [93] concluded that, at the time of their analysis, CINAHL was more comprehensive than either MEDLINE or the Web of Science in covering references in the knowledge utilization field in nursing.

Since most nursing bibliometric studies focused on publications on a certain topic, the most usual approach to retrieve the literature was keyword searching. Nevertheless, other search strategies were applied when relevant. Thus, Huang, Ho and Chuang [47] searched the Web of Science for nursing papers published by authors based in Taiwan to analyse the scholarly literature published in the country.

Finally, some authors focused on the most cited articles according to a citation index. This was the case of bibliometric studies of the top 10% of cited papers in nursing published between 2008 and 2018 [129], or the 100 most cited articles on nursing student education published between 2000 and 2020 [20]. Both studies relied on citation metrics provided by the Web of Science.

Some studies relied exclusively on databases that provide bibliometric indicators. Thus, Smith [97] used the Journal Citation Reports to conduct a longitudinal analysis between 1977 and 2008 of impact factor trends among seven core journals in nursing. Santiago and Carlantonio [92] and Singh and Pandita [96] used bibliometric indicators provided by the Scimago Journal and Country Rank to measure nursing research output in the BRIC countries (Brazil, Russia, India and China) and worldwide, respectively. These databases provide information on the number of articles published and citations received by journals in a field but fail to include any information on individual articles.

3.2.2. Literature published in a set of journals

Instead of retrieving records from literature databases, another option used in nursing bibliometric research was to analyse the articles published in a set of journals selected for their thematic orientation, their geographic origin or their citation impact. When the population of articles was large, some kind of sampling was applied. For instance, in their analysis of Australian nursing research between 1985 and 2010, Wiles, Olds and Williams [112] consistently sampled seven journals at 3‐month intervals every 5 years from the first year of publication to 2010.

Journals and databases can be combined to improve the comprehensiveness of data gathering. Thus, in their analysis of the United Kingdom nursing literature, Traynor et al. [105] initially identified all United Kingdom papers published in 23 nursing journals. These articles were supplemented with papers published in other “general” journals retrieved through a database, if they had one or more of a set of title keywords.

3.2.3. Sets of documents

Some nursing bibliometric studies analysed samples of articles selected according to various criteria. This approach was employed, for instance, in two citation analyses of “distinct” nursing literature [82; 83] that required journal editors to submit articles from their journals representing “distinction” in nursing research, education or practice. Other nursing bibliometric studies focused on particular document types, such as theses and dissertations [95] or nursing guidelines [21].

In terms of time frames, on average, each bibliometric study covered 20.9 years (median = 17 years). Although some bibliometric studies went further back in time, most research was concentrated in the period between 2001 and 2015, with numerous studies taking the year 2000 as the starting point for their analysis.

In terms of size of the populations under study, the biggest samples were those of bibliometric studies based on sets of journals (average = 1693 records, median = 825), followed by studies based on bibliographic databases (average = 1329, median = 433) and those based on sets of documents (average = 159, median = 108). The smaller size of samples in studies based on literature searches is explained by the presence of studies that focused on specific research topics, with little scholarly output. Studies based on sets of documents frequently focused on a relatively small number of theses and dissertations.

3.3. Types of analysis in nursing bibliometric studies

This section focuses on the features of the literature analysed in nursing bibliometric studies. Twelve variables were analysed in the articles surveyed, which revealed different applications of bibliometrics to study nursing science (Figure  2 ).

Types of analyses in nursing bibliometric research.

3.3.1. Years of publication

The most common variable analysed in nursing bibliometric research was the year of publication of the surveyed documents. Most bibliometric studies (96 studies, 74%) included a longitudinal analysis of trends in knowledge production. Although the analysis was usually limited to counting the number of articles published per year, similar analyses can be applied to other variables. For instance, a case study of the Journal of Advanced Nursing [121] discussed the annual trends in number of authors, pages, institutions, references and citations per article.

Most studies revealed an upward trend in the volume of published articles, often interpreted as indicative of growing interest in the subject matter. While such a rise may indeed signify heightened interest, the proliferation of published articles may also be influenced by the expansion of databases used for data collection. The continual enlargement of journals indexed in Scopus and Web of Science contributes to an augmented retrieval of scholarly outputs across various topics.

3.3.2. Document types

As discussed above, most nursing bibliometric studies relied on bibliographic databases to retrieve the literature. These databases mostly index scholarly journals, including different types of documents: articles, editorials, letters, reviews, etc. The classification of documents according to these categories was presented in some nursing bibliometric studies (25 studies, 19%). The analysis of document types can be combined with other variables of interest. For example, Anderson, Keenan and Jones [4] analysed to what extent five nursing terminology sets were used in different document types. Nevertheless, it is important to note that such analyses are often constrained by the database's coverage, which tends to prioritize the indexing of journal articles over other document types. This limitation may impact the comprehensiveness and scope of the analysis.

3.3.3. Language of documents

As in the case of document types, this kind of analysis (11 studies, 9%) relied on the information provided by bibliographic databases. When conducting analyses of languages within the literature, it is crucial to consider that biases inherent in the database's coverage can significantly influence the outcomes. Put simply, the proportion of nursing literature available in various languages as retrieved from databases like Scopus and the Web of Science is contingent upon the language coverage provided by the database itself. Therefore, it may not accurately reflect the entirety of scholarly output in the field.

3.3.4. Authorship

In the analysis of authorship (48 studies, 37%), the most frequent output delivered by nursing bibliometric papers was a list of the most prolific authors. Nevertheless, some studies [e.g., 2; 3; 35; 72] went one step further to analyse whether the distribution of authors followed Lotka's law of productivity. This law describes the frequency of publication by authors in any given field. It states that the number of authors publishing n papers is 1/n 2 of those publishing one paper (Pao,  1985 ).

3.3.5. Affiliations

The analysis of the affiliations of the authors of the literature allowed identification of the most productive institutions (64 studies, 50%) and the most productive countries (69 studies, 53%). In some instances, this analysis became the focus of the study. Thus, Kokol et al. [59] explored the relationship between nursing research literature production and country and health determinants. They concluded that gross domestic product, human development factor, and gross national income were related to nursing research literature productivity.

In addition to institutional affiliations, some nursing bibliometric studies analysed the education background of the authors who contributed to the literature. Thus, Ravelli et al. [90] analysed the training (e.g., nurses, doctors, pharmacists, odontologists, psychologists, etc.) of the authors of Latin‐American literature on nursing and ageing published between 2003 and 2008. In a similar fashion, Marcellus [71] analysed the longitudinal evolution of the presence of nurses, physicians and other health professionals among the authors in The Canadian Nurse .

3.3.6. Collaboration

Research collaboration was explored through the analysis of co‐authorship (39 studies, 30%). The analysis can be purely numerical, i.e., calculating the average number of authors per paper, or can be aimed at identifying the networks of researchers, institutions and countries that publish jointly. For instance, Alcalá‐Albert and Parra‐González [3] built a network of co‐authors who frequently published together in the nursing outputs indexed until 2021 in the Web of Science, whereas Zhu et al. [129] built a network of co‐author institutions in their analysis of the top cited papers in nursing between 2008 and 2018.

In most studies, full counting was used for handling publications with multiple coauthors. However, proper field normalization requires fractional counting (Waltman & van Eck,  2015 ). These two approaches yield different results in co‐authorship networks and journal coupling networks, with fractional counting being preferable over full counting (Perianes‐Rodriguez et al.,  2016 ).

3.3.7. Journals

The core journals in the field can be identified through an analysis of journals that publish nursing literature. This type of analysis was present in 69 studies (53%). Beyond a list of journals sorted by the number of articles published, some researchers [e.g., 3; 35; 67; 68; 79] explored whether journals in their analyses followed Bradford's law of scattering. This law states that, if journals in a field are sorted by number of articles, they can be divided into a nucleus of journals that are more specifically devoted to the subject and several groups containing the same number of articles as the nucleus, when the number of journals in the nucleus and succeeding groups will be as 1:n:n 2 , where n is a multiplier (Desai et al.,  2018 ). However, it is essential to consider that different operationalizations of the concept of “subject” can lead to significantly different lists of core journals (Nicolaisen & Hjørland,  2007 ).

3.3.8. Research designs

Some nursing bibliometric papers (26 studies, 20%) analysed the methodological features of the articles surveyed. For example, in their longitudinal analysis of Australian nursing research, Wiles, Olds and Williams [112] verified an improvement in research designs, with an increasing use of higher research approaches and greater quantification in reporting results. Similarly, Chang et al. [20] analysed the chronological evolution in the statistical analyses employed in the top 100 most cited articles on nursing student education published between 2000 and 2020.

3.3.9. Funding

Although it was not common (14 articles, 11%), some bibliometric studies reported findings on the funding of nursing research. For example, McVicar, Munn‐Giddings and Abu‐Helil [74] analysed the funding sources of nursing literature in the UK that used action research as a methodology. Huang et al. [46] explored institutions funding family nursing research using data from Web of Science.

In this kind of studies, it is necessary to bear in mind that coverage of funding information differs significantly among Scopus, Web of Science and PubMed for the same journals (Kokol,  2023 ; Kokol & Vošner,  2018 ). Consequently, the choice of a bibliographic database could potentially introduce bias into the results. To mitigate this bias, researchers aiming to retrieve funding information related to specific research topics or institutions should consider combining data from all three databases to obtain more complete information.

3.3.10. Topics

Most nursing bibliometric studies (92 studies, 71%) aimed to identify the topics, themes and research hotspots in the literature. Three alternative methods were used for this purpose: manual classification of articles by topic, assignation of articles to the subject categories of journals in the database, and keyword analysis.

In the case of manual classification of articles, the subject categories may be built purposely by researchers, or may rely on existing classification schemes. Using the first approach, Scott et al. [93] assigned articles on research utilization in nursing to ten “domains” created by the authors. Zhang et al. [125] used the International Council of Nurses' Framework of Disaster Nursing Competencies to classify articles on the topic.

In other studies, the classification of articles by topic was not based on the direct examination of papers but on the databases' journal categories. For example, in their analysis of the literature on robots in nursing education, Romero, La Hoz and González [91] classified articles according to the subject areas employed by Scopus to classify the journals.

Finally, some authors used keyword analysis to identify the topics in the literature. Keywords were extracted from titles and abstracts or were provided by the database, such as the Medical Subject Heading in the case of PubMed. The analysis usually consisted of counting the frequency of keywords, to be depicted in word clouds, or identifying co‐occurrence networks of keywords, which were usually clustered and depicted using VOSviewer software (Van Eck & Waltman,  2010 ).

The selection of any of these approaches can significantly influence the outcomes. Journal classifications within databases may not always encapsulate the specific topics or themes explored within individual articles, particularly in multidisciplinary journals or those exploring emerging research areas. Moreover, these classification systems may lack the granularity necessary to distinguish between closely related topics and may encounter issues of inconsistencies.

Employing keywords extracted from titles and abstracts offers a more flexible and tailored method for defining topics and themes. This strategy allows for the inclusion of synonyms, related terms, and variations in spelling or terminology. Utilizing database‐provided keywords presents certain advantages in terms of consistency and comprehensiveness, given that most databases utilize controlled vocabularies and subject indexing to categorize publications. This can ensure consistency in topic identification across various studies. However, predefined keywords may not fully encompass the breadth and diversity of topics within a research area, nor do they necessarily reflect emerging or niche areas that have yet to be integrated into the database's subject indexing.

A combination of both methods may prove beneficial. By extracting keywords from titles and abstracts and cross‐referencing them with database‐provided keywords, researchers can ensure a comprehensive and consistent approach to topic identification.

3.3.11. References

References cited in papers were another feature of interest in nursing bibliometric research. Some articles focused exclusively on references cited in the literature to analyse their characteristics: years of publication, document types, languages, etc. The list of variables susceptible to be analysed in references is as long as the list of variables that can be analysed in the citing articles themselves.

The simplest analysis consisted of measuring the average number of cited references per document and whether there were any differences between, for instance, document types (e.g., whether research papers or clinical studies cite different numbers of sources). Some studies focused on references to particular types of documents. For example, Woods, Phillips and Dudash [115] analysed the references to grey literature (conference proceedings, news, theses and dissertations, etc.) in six nursing journals.

The Price index, that is, the percentage of references that are less than five years old, allowed an exploration of obsolescence of the literature [72]. In studies focusing on the literature published in a particular country, the share of references published in the same country as the surveyed articles allowed the “insularity” of the field to be measured [34; 85]. The interdisciplinarity of the discipline can also be analysed by measuring the share of nursing and non‐nursing references in the nursing literature [35]. Finally, the analysis of references cited in nursing guidelines can be a method to assess their comprehensiveness [21].

Reference Publication Year Spectroscopy (RPYS) is a bibliometric method that can be used to track the historical origins of research fields. RPYS plots the cumulative distribution of cited references of a publication set in terms of the referenced publication years. The peaks in the graph indicate specific publications which were cited frequently within the field (Marx et al.,  2014 ). This method was applied to the global nursing literature [56], cardiovascular nursing [15], nursing informatics [13] or meta‐analysis approaches used in nursing research [55].

3.3.12. Citations

As in the case of references, the citations received by an article may be analysed from multiple points of view: years of publication of citing documents, types of citing documents, citing authors, etc. Again, the simplest analysis consisted of counting the number of citations per paper. To make the analysis more meaningful, citation counts can be combined with other variables to determine, for instance, whether articles are cited more if they are written in international co‐authorship [47] or if they result from funded research [105].

A popular citation indicator at author level is the h index, which combines the productivity and citation impact of an author. The h‐index is defined as the maximum value of h such that the given author has published at least h papers that have each been cited at least h times (De Groote & Raszewski,  2012 ). Goode et al. [40] calculated the h index for nurses at the University of Colorado Hospital in their case study of the contribution of this institution to nursing scholarly literature. Similarly, Singh and Pandita [96] calculated the h index for the countries that contribute to nursing scholarly literature according to the Scimago Journal and Country Rank .

“Sleeping beauties” are publications that go unnoticed for a long time and then, almost suddenly, attract a lot of attention (Van Raan,  2004 ). Železnik, Blažun Vošner and Kokol [121] identified two sleeping beauties in their 40‐year analysis of the Journal of Advanced Nursing .

A possible way to establish associations between research agents is co‐citation, that is, when two articles, authors, journals, etc. are cited together. For instance, in their analysis of the nursing output published in six journals, Giménez‐Espert and Prado‐Gascó [39] built a network of co‐cited articles. Scott et al. [93] built a co‐citation map of the most cited authors in the field of nursing utilization to unveil the structure of the scientific community that works in the field. Guo, Lu and Tian [42] built a network of co‐cited journals in the field of cirrhosis nursing.

In their analysis of “distinct” nursing research, Nicoll et al. [82; 83] analysed three citation features of a set of articles selected by journal editors: persistence (rate of subsequent citations over time), reach (geographic distribution of subsequent citations) and dissemination (specialty of follow‐on citations represented as nursing or another discipline). In addition to persistence, read and dissemination, Waldrop, Carter‐Templeton and Nicoll [108] analysed altmetrics provided by PlumX (usage, captures, mentions and social media) in a case study of the Journal for Nurse Practitioners .

Finally, it should be noted that some of the bibliometric studies identified in this research focus on the bibliometric analysis of highly cited articles. When this approach is used, authors should consider the time lapse needed by articles to accumulate citations. The most cited articles in, say, the past 20 years are not necessarily representative of the more impactful research published in these two decades, since older articles have had more time to accrue citations and may introduce a bias in the sample. This should be acknowledged as a limitation in this kind of studies. Recent groundbreaking research might be overlooked if the analysis focuses solely on the most cited works. This can skew the understanding of current trends and developments in a field.

4. DISCUSSION

4.1. contributions of bibliometric studies to advance nursing research and practice.

Bibliometrics involves the quantitative analysis of scholarly publications. It is used to explore the features of nursing science has sharply increased in recent years. Nevertheless, bibliometrics is an umbrella term that encompasses a wide range of analyses. This study offers a detailed overview of the applications of bibliometrics in nursing research, which suggests new developments for researchers who aim to conduct further bibliometric research in the field.

Most nursing bibliometric studies combine performance analysis with science mapping to advance nursing research and practice. Most papers identify research leaders, collaboration patterns, influential journals, hot topics, research frontiers, etc. This information is useful to assess the maturity of a research topic. In some instances, limited amount of collaborative research and the repeated citation of a few references pinpoint towards the underdevelopment of research fields such as research utilization in nursing [35]. These observations are of interest to policy makers who can become aware of the need to diversify grant support to broaden the scope of nursing research in themes such as artificial intelligence [94] or in genomic nursing science [113].

The identification of research gaps and the establishment of research agendas are among the most usual contributions of bibliometric studies when applied to topics such as burnout among nursing professionals [32] or conflict in nursing [53]. Nursing bibliometric research focused on specific geographic areas can reveal the need of researchers in certain countries to investigate specific patient groups, diseases, treatments or skills for unresearched gaps with national relevance [104]. Even individual case studies focused on a single journal can reflect emerging scientific developments and evolving social values [71].

Bibliometric studies contribute to understanding the global direction of the field and specific research topics. For instance, a bibliometric study on leadership and care in nursing revealed that themes such as job satisfaction, teamwork and retention were researched more intensively whereas patient‐based and fundamental‐care themes, including patient safety, comfort, dignity or privacy were less studied [54]. Similarly, a keyword analysis of studies on workplace incivility in nursing revealed that horizontal/lateral violence and bullying were used interchangeably even though their contents and meaning are quite different [103].

Some bibliometric studies unveil different approaches to research in a certain topic. Keyword co‐occurrence analysis has proved useful to identify how different health sciences address the field of scope of practice, identifying areas where synthesis to find consolidated results may be possible [9]. Using a slightly different approach, bibliometric analysis of the literature on nursing competences allowed to identify different approaches to the topic of nursing competence in the practice‐oriented versus the educational literature [14]. In a similar fashion, bibliometric research can be useful to show the transferability potential of knowledge gained from nursing research to other health professions, as in the case of military nursing research [25].

From a methodological point of view, bibliometric studies are useful to assess the comprehensiveness of systematic reviews as illustrated by a comparative analysis of guidelines for preventing inpatient falls [21]. Low extensiveness revealed certain preferences in how the literature was selected, suggesting how to improve reviews in terms of methodological quality. Citation analysis can also be relevant to show the substantial use of grey literature and the need to apply this knowledge to instruction, research and practice [115].

Our results also illustrate how bibliometrics can improve nursing practice. Empirical evidence of correlation between literature production and well‐being and health determinants of countries can be useful to demonstrate that research is successfully translated into practice [59]. Similarly, a 20‐year bibliometric analysis of nursing research in Australia was useful to demonstrate the increased sophistication in the impact of nursing services on access to care [112].

RPSY is a viable approach to analyse the historical roots of knowledge development that can be useful to better understand current problems in the profession. For instance, it may help nurse practitioners to recognize ingrained cultural traditions and cultural bias, so they can become more culturally sensitive to people from other cultural environments [15]. In a similar fashion, a bibliometric analysis of research in the field of nursing management, religion and spirituality revealed the need that nurses are equipped to develop an understanding of the socio‐religion changes towards personal spiritual inquire and development [23].

Bibliometric methods are useful to improve our understanding of the profession, as evidenced by studies of the literature of robotics in nursing that allowed to identify and classify applications of robotics within patient care areas [19] or a proposal for a categorisation of variants of nurse rounding based on bibliometric data [49].

Bibliometric studies have revealed that nurses should be included in decision‐making policies, as illustrated by a bibliometric study on nurses as agents for achieving environmentally sustainable health systems [69].

Finally, bibliometric studies can enlighten how to improve nursing education, as exemplified by research that identified core competencies in critical thinking, complex problem solving or computation thinking [99]. Another bibliometric analysis of simulation in nursing education showed that psychiatric simulations and critical care simulation were core priorities in nursing education [111].

4.2. Methodological approaches in nursing bibliometric research

Our results show that the topics of nursing bibliometric research revolve around six main areas. Most studies aim to analyse the nursing scholarly literature, either globally or focusing on particular research topics. Other issues of interest for nursing bibliometric research are nursing education, nursing as a profession, nursing research using a particular research method and nursing literature published in a particular country or region. This landscape is consistent with the descriptions of the nursing research activity provided by Alcalá‐Albert and Parra‐González ( 2021 ) or Wang et al. ( 2022 ) who observed an upward trend in publications on topics such as nursing education and the high burden of care among nurses, resulting in stress and burnout syndrome.

Regarding data sources, most studies rely on bibliographic databases, either multidisciplinary citation indexes (the Web of Science and Scopus) or index and abstract databases in the health sciences (PubMed and CINAHL). Previous research has shown that Scopus offers better coverage than the Web of Science for reporting nursing publication metrics (Powell & Peterson,  2017 ). These sources are suitable for systematic reviews and meta‐analysis, offering effective and efficient search results with regards to precision, recall and reproducibility (Gusenbauer,  2022 ; Gusenbauer & Haddaway,  2020 ). Two studies referred to the use of Google Scholar as a data source, although research has shown its unreliability, as evidenced by its inability to provide consistent results for identical queries (Gusenbauer & Haddaway,  2020 ). There was no mention of new open bibliographic sources such as Crossref, Dimensions or OpenAlex that supplement traditional citation indexes in bibliometric studies (Chawla,  2022 ). Research suggests that these new databases have a similar or better coverage than traditional sources (Harzing,  2019 ; Martín‐Martín et al.,  2021 ). Further studies are needed to confirm whether these sources may serve as good alternatives to Scopus and the Web of Science for literature reviews and citation analysis in nursing.

Our findings suggest several potential enhancements in nursing bibliometric studies. For instance, in chronological studies, where trends often reveal an increase in article publications across various topics, it is crucial to consider the expanding pool of indexed journals. This consideration ensures an accurate interpretation of trends and minimizes the risk of misinterpretations. Similarly, investigations into document types or languages should account for the indexing policies of scholarly databases like Scopus and Web of Science, which may lead to an overrepresentation of English publications.

Our exploration into authorship and collaboration analyses highlights the prevalent use of full counting, but fractional counting emerges as a superior method for proper field normalization and network construction, thereby enhancing the precision and reliability of results. Moreover, when identifying core journals and applying Bradford's law of scattering, careful consideration of different subject operationalizations is essential, as these choices profoundly influence outcomes.

The challenges surrounding research funding source identification underscore the imperative of integrating multiple sources to ensure comprehensive and accurate analysis, given the inconsistent information across databases. Our analysis also shows the methodological intricacies of determining research topics in nursing literature. We underscore the limitations of journal classifications in capturing specific topics or themes within individual articles, advocating for more flexible approaches such as keyword extraction from titles and abstracts, combined with database‐provided keywords.

We provide examples of twelve bibliometric approaches for the analysis of scholarly outputs in nursing. Possibly, the most surprising gap in nursing bibliometric literature is the absence of gender analyses of authorship in the discipline. Bibliometric studies confirming gender imbalances in research output are prevalent (Larivière et al.,  2013 ), including nursing research (Porter,  2018 ; Shields et al.,  2011 ). Given that women make up a large majority of members of the profession and the academic discipline of nursing, the lack of further studies on the analysis of gender imbalance among authors in the field is surprising.

4.3. Limitations

The scope of our analysis is limited by the coverage of Scopus, which has been criticized for its overrepresentation of English language journals (Mongeon & Paul‐Hus,  2016 ) and its underrepresentation of journals from the Global South (Borrego et al.,  2023 ). In addition, our search was limited to the presence of the term “bibliometrics” in the titles of the documents, which prevented the retrieval of related concepts such as “citation analysis”, “impact factor” or “scientometrics”, to name just a few. Nevertheless, we consider that the papers surveyed offer a fairly complete overview of the applications of bibliometrics in nursing.

5. CONCLUSION

Bibliometric studies have proved useful to map nursing research. These studies have been relevant to quantify the scholarly output in the field, to understand the social structure of the scientific community that engages in knowledge creation, and to assess the maturity of the discipline. The analysis of references and citations has been applied to measure the consumption of scientific information and has proved to be suitable to assess the comprehensiveness of systematic reviews and clinical guidelines. Further research is still needed to explore the coverage of the nursing literature by new bibliographic data sources and to explore topics such as gender imbalance in research, an issue of great relevance in nursing science.

Research Topics

Navigating the trust gap: three research topics on tech, ai, and the future of public confidence in science.

Technological advancements have changed how we consume and interact with information. Social media, search engines, and artificial intelligence (AI)-powered algorithms make knowledge accessible at an unprecedented scale. However, these developments have also created new opportunities for misinformation and manipulation, ultimately undermining public trust in institutions, including scientific ones.

In the information age, fostering trust and confidence among the public –particularly in the science community—prompted a community of scientists to establish the Research Topic The Erosion of Trust in the 21st Century: Origins, Implications, and Solutions . Inspired by the work of this group of researchers, we’ve curated three Research Topics that investigate the complex interplay between technology, health, and society's trust in scientific research.

These topics explore reflections on how to develop technology that benefits society, the implications of using AI in public health data, and public risk perception and its impacts on policy, decision-making, and innovation.

All articles are openly available to view and download.

Research quantifying “nociception” could help improve management of surgical pain

Press contact :.

The degree to which a surgical patient’s subconscious processing of pain, or “nociception,” is properly managed by their anesthesiologist will directly affect the degree of post-operative drug side effects they’ll experience and the need for further pain management they’ll require. But pain is a subjective feeling to measure, even when patients are awake, much less when they are unconscious. 

In a new study appearing in the Proceedings of the National Academy of Sciences , MIT and Massachusetts General Hospital (MGH) researchers describe a set of statistical models that objectively quantified nociception during surgery. Ultimately, they hope to help anesthesiologists optimize drug dose and minimize post-operative pain and side effects.

The new models integrate data meticulously logged over 18,582 minutes of 101 abdominal surgeries in men and women at MGH. Led by Sandya Subramanian PhD ’21, an assistant professor at the University of California at Berkeley and the University of California at San Francisco, the researchers collected and analyzed data from five physiological sensors as patients experienced a total of 49,878 distinct “nociceptive stimuli” (such as incisions or cautery). Moreover, the team recorded what drugs were administered, and how much and when, to factor in their effects on nociception or cardiovascular measures. They then used all the data to develop a set of statistical models that performed well in retrospectively indicating the body’s response to nociceptive stimuli.

The team’s goal is to furnish such accurate, objective, and physiologically principled information in real time to anesthesiologists who currently have to rely heavily on intuition and past experience in deciding how to administer pain-control drugs during surgery. If anesthesiologists give too much, patients can experience side effects ranging from nausea to delirium. If they give too little, patients may feel excessive pain after they awaken.

“Sandya’s work has helped us establish a principled way to understand and measure nociception (unconscious pain) during general anesthesia,” says study senior author Emery N. Brown , the Edward Hood Taplin Professor of Medical Engineering and Computational Neuroscience in The Picower Institute for Learning and Memory, the Institute for Medical Engineering and Science, and the Department of Brain and Cognitive Sciences at MIT. Brown is also an anesthesiologist at MGH and a professor at Harvard Medical School. “Our next objective is to make the insights that we have gained from Sandya’s studies reliable and practical for anesthesiologists to use during surgery.”

Surgery and statistics

The research began as Subramanian’s doctoral thesis project in Brown’s lab in 2017. The best prior attempts to objectively model nociception have either relied solely on the electrocardiogram (ECG, an indirect indicator of heart-rate variability) or other systems that may incorporate more than one measurement, but were either based on lab experiments using pain stimuli that do not compare in intensity to surgical pain or were validated by statistically aggregating just a few time points across multiple patients’ surgeries, Subramanian says.

“There’s no other place to study surgical pain except for the operating room,” Subramanian says. “We wanted to not only develop the algorithms using data from surgery, but also actually validate it in the context in which we want someone to use it. If we are asking them to track moment-to-moment nociception during an individual surgery, we need to validate it in that same way.”

So she and Brown worked to advance the state of the art by collecting multi-sensor data during the whole course of actual surgeries and by accounting for the confounding effects of the drugs administered. In that way, they hoped to develop a model that could make accurate predictions that remained valid for the same patient all the way through their operation.

Part of the improvements the team achieved arose from tracking patterns of heart rate and also skin conductance. Changes in both of these physiological factors can be indications of the body’s primal “fight or flight” response to nociception or pain, but some drugs used during surgery directly affect cardiovascular state , while skin conductance (or “EDA,” electrodermal activity) remains unaffected. The study measures not only ECG but also backs it up with PPG, an optical measure of heart rate (like the oxygen sensor on a smartwatch), because ECG signals can sometimes be made noisy by all the electrical equipment buzzing away in the operating room. Similarly, Subramanian backstopped EDA measures with measures of skin temperature to ensure that changes in skin conductance from sweat were because of nociception and not simply the patient being too warm. The study also tracked respiration.

Then the authors performed statistical analyses to develop physiologically relevant indices from each of the cardiovascular and skin conductance signals. And once each index was established, further statistical analysis enabled tracking the indices together to produce models that could make accurate, principled predictions of when nociception was occurring and the body’s response.

Nailing nociception

In four versions of the model, Subramanian “supervised” them by feeding them information on when actual nociceptive stimuli occurred so that they could then learn the association between the physiological measurements and the incidence of pain-inducing events. In some of these trained versions she left out drug information and in some versions she used different statistical approaches (either “linear regression” or “random forest”). In a fifth version of the model, based on a “state space” approach, she left it unsupervised, meaning it had to learn to infer moments of nociception purely from the physiological indices. She compared all five versions of her model to one of the current industry standards, an ECG-tracking model called ANI.

Each model’s output can be visualized as a graph plotting the predicted degree of nociception over time. ANI performs just above chance but is implemented in real-time. The unsupervised model performed better than ANI, though not quite as well as the supervised models. The best performing of those was one that incorporated drug information and used a “random forest” approach. Still, the authors note, the fact that the unsupervised model performed significantly better than chance suggests that there is indeed an objectively detectable signature of the body’s nociceptive state even when looking across different patients.

“A state space framework using multisensory physiological observations is effective in uncovering this implicit nociceptive state with a consistent definition across multiple subjects,” wrote Subramanian, Brown, and their co-authors. “This is an important step toward defining a metric to track nociception without including nociceptive ‘ground truth’ information, most practical for scalability and implementation in clinical settings.”

Indeed, the next steps for the research are to increase the data sampling and to further refine the models so that they can eventually be put into practice in the operating room. That will require enabling them to predict nociception in real time, rather than in post-hoc analysis. When that advance is made, that will enable anesthesiologists or intensivists to inform their pain drug dosing judgements. Further into the future, the model could inform closed-loop systems that automatically dose drugs under the anesthesiologist’s supervision.

“Our study is an important first step toward developing objective markers to track surgical nociception,” the authors concluded. “These markers will enable objective assessment of nociception in other complex clinical settings, such as the ICU [intensive care unit], as well as catalyze future development of closed-loop control systems for nociception.”

In addition to Subramanian and Brown, the paper’s other authors are Bryan Tseng, Marcela del Carmen, Annekathryn Goodman, Douglas Dahl, and Riccardo Barbieri.
