Abstract

Importance: There is much interest in the clinical integration of large language models (LLMs) in health care. Many studies have assessed the ability of LLMs to provide health advice, but the quality of their reporting is uncertain. Objective: To perform a systematic review to examine the reporting variability among peer-reviewed studies evaluating the performance of generative artificial intelligence (AI)–driven chatbots for summarizing evidence and providing health advice to inform the development of the Chatbot Assessment Reporting Tool (CHART). Evidence Review: A search of MEDLINE via Ovid, Embase via Elsevier, and Web of Science from inception to October 27, 2023, was conducted with the help of a health sciences librarian to yield 7752 articles. Two reviewers screened articles by title and abstract followed by full-text review to identify primary studies evaluating the clinical accuracy of generative AI-driven chatbots in providing health advice (chatbot health advice studies). Two reviewers then performed data extraction for 137 eligible studies. Findings: A total of 137 studies were included. Studies examined topics in surgery (55 [40.1%]), medicine (51 [37.2%]), and primary care (13 [9.5%]). Many studies focused on treatment (91 [66.4%]), diagnosis (60 [43.8%]), or disease prevention (29 [21.2%]). Most studies (136 [99.3%]) evaluated inaccessible, closed-source LLMs and did not provide enough information to identify the version of the LLM under evaluation. All studies lacked a sufficient description of LLM characteristics, including temperature, token length, fine-tuning availability, layers, and other details. Most studies (136 [99.3%]) did not describe a prompt engineering phase in their study. The date of LLM querying was reported in 54 (39.4%) studies. Most studies (89 [65.0%]) used subjective means to define the successful performance of the chatbot, while less than one-third addressed the ethical, regulatory, and patient safety implications of the clinical integration of LLMs. Conclusions and Relevance: In this systematic review of 137 chatbot health advice studies, the reporting quality was heterogeneous and may inform the development of the CHART reporting standards. Ethical, regulatory, and patient safety considerations are crucial as interest grows in the clinical integration of LLMs.

TL;DR

This systematic review of 137 chatbot health advice studies found substantial heterogeneity and incomplete reporting of LLM characteristics, prompt engineering, query strategy, and performance evaluation. Most studies evaluated closed-source ChatGPT models and used investigator opinion rather than evidence-based reference standards, with less than one-third addressing ethics, patient safety, or regulation.

Key findings

  • Of 137 CHAS, 135 (98.5%) assessed ChatGPT and 136 (99.3%) evaluated inaccessible/closed-source models; only 1 (0.7%) fully described the LLM version, and 36 (26.3%) described none of the LLM characteristics.
  • Performance evaluation was often subjective: 89 studies (65.0%) used investigators’ opinion without a reference standard, while 21 (15.3%) used clinical practice guideline recommendations; 18 (13.1%) described a standardized evaluation process and 16 (11.7%) reported blinding.
  • Reporting of methods was incomplete: 121 (88.3%) did not describe chatbot selection, 40 (29.2%) did not describe query strategy, 37 (27.0%) did not describe prompt source, 136 (99.3%) did not describe prompt testing/engineering, and 20 (14.6%) used standardized prompts.
  • Ethical, safety, and regulatory implications were addressed by 45 (32.8%) for ethics, 44 (32.1%) for patient safety, and 22 (16.1%) for regulation of LLMs.

Methods

  • Systematic review following PRISMA; protocol prospectively registered on Open Science Framework; searched MEDLINE via Ovid, Embase via Elsevier, and Web of Science on October 27, 2023.
  • Two independent researchers screened titles/abstracts and full texts, with a third resolving disagreements; 7,752 articles reviewed yielded 137 eligible CHAS.
  • Data extracted in Covidence; descriptive statistics and narrative synthesis were used, with no meta-analysis planned due anticipated heterogeneity; quality of evidence was not evaluated due lack of validated risk-of-bias tools for CHAS.

Limitations

  • Stated: reporting in CHAS may change beyond review time due the dynamic nature of the field; much included literature used hypothetical patient cases; there is a paucity of literature detailing ethical and regulatory considerations; future patient-centered prospective research is needed.
  • Stated: quality of evidence was not evaluated because no high-quality validated risk-of-bias tools were available for CHAS.
  • Evident from the text: heterogeneity in study subjects and designs precluded meta-analysis; the review describes reporting practices and cannot establish causal effects of reporting on clinical outcomes.

    “To the best of our knowledge, there have been no previous studies on patient safety of patient-facing applications for a wide range of primary care questions that patients are likely to ask.”

    From Large language models provide unsafe answers to patient-posed medical questions (2026) · cites this paper as [10]

    The Discussion > Limitations section says that much of the reviewed literature used hypothetical patient cases and calls for patient-centered, prospective research; it also identifies a paucity of work addressing patient-safety considerations. It does not establish that no previous study assessed the safety of patient-facing applications across a wide range of likely primary care questions. No page number is available in our copy. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • A recent review found that the majority of studies (68%) on LLMs for medical advice did not consider patient safety.

    “Within this review, the authors noted that the majority of studies (68%) did not consider patient safety.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Percentage for omitted chatbot responses is incorrect

    Minor

    Twenty-nine of 137 studies is 21.2%, not 21.7%.

    Reported 21.7 · recomputed 21.167883

  • Patient-safety percentage is incorrect in Table 2

    Minor

    The table gives 32.8% for 44 of 137 studies; the percentage is 32.1%, as stated later in the text.

    Reported 32.8 · recomputed 32.116788

  • A study is listed as both giving and not giving a chatbot-selection reason

    Minor

    Study 33 appears under selection based on accessibility and under selection method "Not described."

  • Power-calculation count conflicts with its study list

    Minor

    The row says 3 studies performed a power calculation but lists five study references.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-07.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-07.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
