ABSTRACT

Objective: To map the scientific output and thematic trends in the use of generative artificial intelligence (GenAI) and large language models (LLMs) as methodological support tools in health research. Method: Bibliometric study conducted in September 2026 in the PubMed, Scopus, and Web of Science databases. Records were screened through a hybrid (human–AI) pipeline, in which an LLM applied predefined criteria and a human reviewer checked the results. Data were analyzed in RStudio using the bibliometrix package and its biblioshiny interface. Results: The final corpus comprised 552 documents from 337 sources, with a mean document age of 0.88 years and an annual growth rate of 70.7%. The United States accounted for the largest number of author affiliations, followed by China. The literature showed high dispersion across journals and a strong concentration of occasional authors (89.2% with a single publication), along with modest international collaboration (14.7%). The thematic map revealed that motor themes remain centered on the generic use of LLMs and ChatGPT, whereas specific methodological applications have not yet formed consolidated clusters. Conclusion: The use of GenAI and LLMs as methodological support in health research is an emerging and rapidly expanding field, but it still lacks a consolidated thematic structure and established publication venues. Consolidating the field will require normative validation criteria, transparent reporting, strict human oversight, and AI literacy among researchers, so as to safeguard the integrity of the scientific evidence produced, with direct implications for the quality of practice and the safety of health care.

INTRODUCTION

Generative artificial intelligence (GenAI), particularly large language models (LLMs), has rapidly evolved from a writing assistant into a tool applied in domains of high epistemic complexity, including several core stages of the scientific research process(1). In the biomedical ecosystem, this paradigm shift has been accompanied by the expansion of artificial intelligence (AI)-assisted tools for literature discovery and exploration, ranging from text-mining platforms to relational and semantic knowledge representation(2,3).

In health research, evidence synthesis has emerged as one of the main domains of application for GenAI and LLMs. These models are increasingly being incorporated into the development of search strategies, automated or semi-automated literature screening, parameterized data extraction, and the appraisal of methodological quality or risk of bias. However, evidence synthesized in a recent scoping review cautions that the technological maturity of these tools does not yet guarantee their reproducibility or accuracy without critical oversight(4).

Although the volume of publications on AI in health has grown exponentially, studies devoted to strictly methodological applications within the research workflow remain diluted among studies focused on diagnostic support, health education, and academic writing assistance. Preliminary searches in PubMed, Scopus, and Web of Science confirmed the absence of bibliometric studies that map, with scientific rigor and systematic detail, the use of these technologies as methodological support in health research. This gap matters because health research depends on the timely and rigorous production of evidence to inform care, guideline development, and health policy. By supporting labor-intensive stages such as searching, screening, data extraction, and synthesis, GenAI and LLMs have great potential to streamline the evidence production cycle, provided that their technical validation, accuracy, and procedural reproducibility are properly ensured(4,5).

In this sense, understanding how this field has been taking shape makes it possible to identify which stages of health research already concentrate efforts, which authors, institutions, and sources are driving scientific output, and which gaps remain. This overview can guide research priorities and promote the use of GenAI and LLMs in ways that are more consistent with the needs and rigor of health research. Bibliometric analysis allows researchers to examine the growth of scientific output, collaboration networks, and the themes that structure the knowledge produced, offering an accurate picture of the field's stage of maturity(6,7). Accordingly, this study aims to map the scientific output and thematic trends in the use of GenAI and LLMs as methodological support tools in health research.

 

METHOD

This is a scientometric and bibliometric study, characterized by the application of quantitative methods to analyze scientific output in a specific field of knowledge. Bibliometrics uses statistical indicators to examine patterns of publication, citation, and scientific collaboration, making it possible to identify knowledge structures, productivity dynamics, and the thematic domains of a discipline(6,7).

 

Research question

The guiding question of the study was: What is the bibliometric profile, and what are the thematic trends, of the scientific literature on GenAI and LLMs used as methodological support tools in health research?

 

Eligibility criteria

We included documents in which GenAI, especially LLMs, was used, evaluated, or discussed specifically as support for at least one methodological stage of health research. Eligible stages included study conception and methodological design, search strategy development, screening of titles, abstracts, or full texts, data extraction and synthesis, appraisal of methodological quality or risk of bias, quantitative or qualitative data analysis, and research hypothesis generation.

We excluded documents that addressed these technologies exclusively in the context of clinical practice or patient care, health education or training, scientific writing or manuscript editing, or that merely mentioned AI without an identifiable methodological application. Studies outside the health field were also excluded.

No restrictions were applied regarding language, document type, or publication period.

 

Literature search

Searches were conducted on September 1, 2026, in the indexed databases PubMed, Scopus, and Web of Science. The strategies combined the controlled vocabulary of Medical Subject Headings (MeSH) with free-text terms related to GenAI and LLMs, the research process, and health research. Boolean operators and exclusion terms were also used to reduce the retrieval of studies focused exclusively on clinical applications, health education, or scientific writing. The complete search strategies are available for audit in the project's Open Science Framework (OSF) repository, under DOI: 10.17605/OSF.IO/NC8K9.

 

GenAI-assisted study selection

A computational workflow was developed in Python to automate and log deduplication, record classification, and screening decisions. The workflow was built with the support of the GenAI tools Codex, by OpenAI, and Claude Code, by Anthropic, using Visual Studio Code, version 1.137.0, as the development environment. The eligibility criteria and the structured prompt were defined and iteratively refined by the researcher throughout this process. The source code and the version of the prompt used for classification are available in the public GitHub repository enfermagempesquisadora/genai-health-research-screening.

After deduplication by exact and semantic matching, titles and abstracts were processed with the support of the LLM Claude. For each record, the model indicated whether to include, exclude, or classify it as uncertain, and also recorded the exclusion category (when applicable), a brief justification, an excerpt from the title or abstract supporting the decision, and its self-reported confidence level. Supporting excerpts were automatically checked against the source text. The researcher reviewed all classifications and prioritized the assessment of records classified as uncertain, making the final screening decisions under full human oversight.

 

Data processing and analysis

Data were extracted, harmonized, and analyzed in the R environment (via the RStudio interface), using the bibliometrix(6) package and its graphical interface, biblioshiny. Bibliometrix is an open-source tool for bibliometric analysis, with advanced features for assessing productivity, collaboration, citation, and science mapping(6). Complementary descriptive analyses were performed in Microsoft Excel spreadsheets.

The informetric analysis was structured around the three classic laws of bibliometrics: 1) Bradford's Law (which assessed the dispersion of articles across publication sources, allowing the empirical delimitation of the core journals of the corpus)(8); 2) Lotka's Law (which examined the distribution of author productivity, testing the statistical fit between the observed distribution and the theoretical power-law model using the Kolmogorov-Smirnov test)(9); and 3) Zipf's Law (which described the frequency distribution of terms, underpinning the keyword co-occurrence analyses and the conceptual structure of the field)(10).

We also analyzed annual output, annual growth rate, document type and language, mean publication age, geographic distribution of author affiliations, most represented institutions, most productive and most cited countries, most productive or most cited sources and authors, keyword co-occurrence, and thematic mapping. Output and impact indicators included number of publications, total citations, and citations per document. Citations were taken as recorded in the metadata of the imported records and interpreted as descriptive measures of the corpus, given the differences in coverage across databases(11).

The strategic diagram positioned the thematic clusters in a two-dimensional space according to centrality (degree of relevance and inter-cluster connectivity) and density (degree of internal development of the cluster). Themes were classified into four quadrants: motor themes, niche themes, emerging or declining themes, and basic or transversal themes.

 

Ethical aspects

Because the study used only bibliographic records and publicly available information, with no identifiable participant data, it did not require review by the CEP/Conep System, in accordance with National Health Council (CNS) Resolution No. 510/2016(12). GenAI tools were used to support the development of the analysis workflow, the screening of records, and the writing of the manuscript, under the researcher's supervision and the direct intellectual responsibility of the authors.

 

RESULTS

Selection flow and corpus eligibility

A total of 2,707 records were identified in the selected databases. After removal of 1,116 duplicates (1,042 identified by DOI and 74 by title and publication year), 1,591 unique records underwent title and abstract screening. The hybrid (human–AI) screening pipeline yielded 552 records eligible for the bibliometric corpus and 938 exclusions. Of the excluded records, 587 were off-topic, 287 addressed clinical applications, 34 dealt with scientific writing, 29 with health education, and one had no identifiable methodological application of its own.

The 101 records initially classified as uncertain were excluded from the final corpus after qualitative assessment, as it could not be confirmed that GenAI or LLMs were used or evaluated in, or supported, a methodological stage of health research. These also included off-topic studies, studies focused on clinical applications, scientific writing, or health education, and documents with no methodological content of their own. Figure 1 shows the study selection flow.

Characteristics and evolution of scientific output

The 552 documents were distributed across 337 sources. Original journal articles predominated (n=425; 77.0% of the corpus), followed by conference papers (n=68), reviews (n=38), letters (n=13), editorials (n=3), book chapters (n=3), and notes (n=2). English was the predominant language, present in 98.7% of the records. The mean number of citations per document was 2.62.

Scientific output spanned the publication years 2016 to 2027 (Figure 2). One document was identified in 2016, with no records between 2017 and 2022. From 2023 onward, output increased markedly, with 19 documents in 2023, 98 in 2024, 223 in 2025, and 210 up to September 1, 2026. The only document recorded for 2027 was a conference paper already available online in 2026 but assigned to a 2027 volume. This record was kept in the corpus and was not interpreted as a trend in output after the search cutoff date. The mean document age was 0.88 years, underscoring how recent the field is.

Dispersion of publication sources and citation impact (Bradford's Law)

The distribution of the 337 sources into Bradford zones identified a core of 27 sources, accounting for 187 documents, or 33.9% of the corpus (Figure 3). The second zone comprised 127 sources and 182 documents, while the third included 183 sources and 183 documents. The Bradford model showed an excellent linear fit (R² = 0.9249), with a multiplier of 3.07. The Kolmogorov-Smirnov test confirmed a statistical discontinuity between the observed empirical distribution and the ideal theoretical model (D = 0.1899; p < 0.001).

Among the articles with the highest global citation counts, those focused on semantic exploration and evidence synthesis stood out. The 2024 article by Wei CH on the PubTator 3.0 platform was the most cited in the corpus (n=104), followed by the studies by Lieberum JL (2025; n=103), Aljamaan F (2024; n=97), Wang S (2024; n=92), and Jin Q (2024; n=91).

 

Authorship, productivity, and collaboration patterns (Lotka's Law)

The corpus included 2,914 authors. Wang Y was the most productive author (n=18), followed by Wang Z (n=13), Chen Y (n=12), and Li Y (n=12). Output was predominantly collaborative, with a mean of 6.32 co-authors per article. Only 21 documents (3.8%) were single-authored. The international collaboration rate was 14.7%.

Applying Lotka's Law showed that 2,599 authors (89.2% of the total) published only one article in the field (Table 2). The empirical distribution differed from the classic theoretical Lotka model, with exponent β = 2.0 (D = 0.6429; p = 0.006). However, the power-law model fitted to the corpus yielded β = 2.87 (constant C = 0.444; R² = 0.928) and did not differ significantly from the observed data (D = 0.2857; p = 0.617). This high β exponent reflects an atypical concentration of occasional authors, characteristic of emerging fields.

Geographically, the United States led in the frequency of affiliations (881 occurrences), followed by China (502 occurrences). The most frequent institution was Lanzhou University (n=102), followed by the National Institute on Aging (n=47), University of California (n=44), McMaster University (n=37), and University of Pennsylvania (n=35). In terms of citations by country of affiliation, the United States accumulated 228 citations (mean of 9.9 citations per article), whereas China totaled 14 citations (mean of 2.0 per article). Jin Q had the highest number of citations among authors, with 195, while Wang Y stood out for productivity.

 

Conceptual structure and thematic map

The two-dimensional thematic map (Figure 4), built from the authors' keywords, organized the conceptual structure into four clusters, as follows:

  1. Motor Themes (upper-right quadrant): two well-defined clusters were identified. The first grouped the terms “large language model”, “language model”, and “computational linguistics”; the second brought together “ChatGPT”, “human”, and “article”, indicating the strong development and methodological centrality of LLMs in the research ecosystem.

  2. Emerging or Declining Themes (lower-left quadrant): this quadrant grouped the terms “humans”, “large language models”, and “artificial intelligence”, as well as a cluster formed by “social media”, “mental health”, and “United States”.

  3. Niche and Basic Themes: No structured clusters were identified in these quadrants, reinforcing the concentrated and still dynamic nature of the literature analyzed.

DISCUSSION

Growth dynamics and stage of consolidation of the field

Compared with broader bibliometric analyses of GenAI in health, the literature focused strictly on methodological support for research is still more circumscribed and at an early stage of consolidation. A bibliometric analysis of ChatGPT in health, which included clinical, educational, and patient communication applications, gathered 594 publications and recorded an annual growth of 91.18% between 2023 and 2024(13). Another analysis, focused on the use of the same LLM in education in Asia, identified 1,665 documents published between 2022 and 2025, with an annual growth rate of 545.53%(14). In the present study, this rate was 70.7%, lower than those observed in both analyses. Differences in databases, time frames, and search strategies preclude a direct comparison of these results. Even so, the findings show that the use of GenAI and LLMs as methodological support in health research is also expanding, albeit less steeply and with greater rigor in the selection of use cases.

 

Informetrics of authorship networks, sources, and transnational collaboration

Taken together with the collaboration indicators, the analysis of Bradford's and Lotka's Laws points in the same direction. Although some journals already concentrate a substantial share of the publications, the documents are spread across 337 sources, indicating that the topic does not yet have fully established dissemination venues. Author productivity was also heavily concentrated in one-off contributions, with 89.2% of authors appearing in only one document, reflecting a high proportion of transient authors, and productivity dropped more steeply than predicted by the classic Lotka model (β = 2.87). International collaboration, present in 14.7% of the documents, completes this picture by showing that cross-country connections are still infrequent. Overall, these results suggest that the growth of the literature has been driven more by the entry of new authors and the spread of the topic across different journals than by the formation of a stable, consolidated research community.

 

Geographic hegemony and implications for scientific equity

The concentration of affiliations in the United States and China should be interpreted in light of cross-country differences in infrastructure, governance, workforce, and institutional capacity for adopting AI in health(15). Although this study did not directly assess these inequalities, the results show that a substantial share of the knowledge on the use of GenAI in health research is being produced in countries with high scientific and technological capacity. This predominance may shape the applications investigated, the criteria used to evaluate them, and the problems considered priorities. Technologies developed and validated predominantly in these settings may therefore not respond equally well to the needs of health systems and populations operating under resource constraints or with distinct epidemiological profiles.

 

Evolution of thematic structure and maturity

The thematic map showed that the most developed and connected themes remain centered on the generic evaluation of LLMs, with ChatGPT standing out. This indicates that the literature is still organized around the technologies themselves and their potential uses, whereas more specific methodological applications (such as automated evidence synthesis or risk-of-bias modeling) have not yet emerged as consolidated themes. The absence of basic or niche themes and the classification of the remaining clusters as emerging or declining reinforce this picture. Thus, although GenAI is already being incorporated into different stages of health research, no well-defined thematic structure around specific methodological uses can yet be observed.

 

Methodological uncertainties, integrity, and reproducibility

The literature already describes the use of GenAI in searching, screening, data extraction, risk-of-bias assessment, and evidence synthesis. However, consistent standardized criteria are still lacking to define at which research stages LLMs can be used safely, what error levels are acceptable, and how their performance should be audited and validated(4,5). In health research, this uncertainty is especially relevant because errors in identifying, selecting, or interpreting evidence can compromise reviews that inform protocols, guidelines, policies, and care decisions, with potential repercussions for the quality and safety of care(5).

For this reason, the incorporation of GenAI into health research should be guided not only by its potential to speed up stages of the work but also by its capacity to preserve the rigor, reliability, and reproducibility of the evidence produced. Reports of its use should include the tool and its version, the purpose of use, the instructions employed, the validation methods, the verification of outputs, and the privacy aspects involved(16). This level of detail helps clarify the benefits and limitations of the technology in the context in which it was used and makes the decisions taken throughout the process auditable. Even when these tools are used, the planning, validation, and interpretation of results remain the sole responsibility of the researchers(16).

 

AI literacy and the transformation of the researcher's professional identity

Finally, the expanding use of GenAI and LLMs in the research process brings new challenges for researcher training. Their use requires not only operational command of the tools but also AI literacy and the ability to critically appraise generated outputs, recognize algorithmic limitations, and justify methodological decisions. A systematic review of AI education and training for health workers pointed to the need for training initiatives covering technical skills, critical appraisal, ethical aspects, and the safe use of these technologies(17), while another study showed that professional identity may be related to AI readiness among health workers(18). These findings suggest that researcher training needs to keep pace with these changes, addressing not only the competencies required to use GenAI but also an understanding of researchers' role and responsibility in the face of new ways of producing knowledge(17,18).

 

Study limitations

As limitations, the results reflect the databases consulted, the search strategy, and the time frame adopted. Citation indicators were obtained from the imported metadata and should be interpreted as descriptive measures of the corpus, since coverage varies across sources. The use of an LLM to support screening should also be considered, as automated classifications are prone to errors and may have influenced the composition of the corpus despite human oversight. At the same time, using it in the selection process itself made it possible to explore, in practice, one of the methodological applications that are the object of this study. Moreover, because the literature on this topic is growing rapidly, the overview presented is bound to the period analyzed and may change as new studies are published.

 

CONCLUSION

This study showed that the use of GenAI and LLMs as methodological support in health research is a recent and expanding field, yet one still marked by the dispersion of publications across authors and journals, low international collaboration, and the absence of a consolidated thematic structure around specific methodological applications. The findings indicate that the adoption of these technologies is advancing faster than the development of a scientific and regulatory foundation capable of guiding their use in health research.

We recommend that future studies validate the performance of these tools in specific methodological stages, that their use be reported in a standardized and transparent manner, with human oversight, and that AI literacy be incorporated into researcher training, including in nursing. We also recommend strengthening collaborative networks, expanding research in Global South countries, which tend to adopt AI technologies developed in other contexts, and periodically updating this mapping. These measures are necessary because errors in searching, selecting, analyzing, and synthesizing evidence can affect the quality and safety of care, as well as health guidelines and policies.

ARTIFICIAL INTELLIGENCE USE STATEMENT

GenAI tools were used at different stages of this study. Codex and Claude Code were used to develop the Python computational workflow. Title and abstract screening was performed with the support of Claude Opus 5, based on eligibility criteria and a prompt defined and refined by the researcher. ChatGPT and Claude were also used to support the organization, writing, and language editing of the manuscript.

These tools were used under full human oversight. The classifications generated by Claude during screening were reviewed by the researcher, with priority given to records classified as uncertain and decisions adjusted when necessary. The definition of eligibility criteria, the methodological decisions, the interpretation of results, and the conclusions remained the responsibility of the researchers, who critically reviewed the final version and took full responsibility for its content.
