Integrating large language models in biostatistical workflows for clinical and translational research
Open accessAbstract
Introduction: Biostatisticians increasingly use large language models (LLMs) to enhance efficiency, yet practical guidance on responsible integration is limited. This study explores current LLM usage, challenges, and training needs to support biostatisticians. Methods: A cross-sectional survey was conducted across three biostatistics units at two academic medical centers. The survey assessed LLM usage across three key professional activities: communication and leadership, clinical and domain knowledge, and quantitative expertise. Responses were analyzed using descriptive statistics, while free-text responses underwent thematic analysis. Results: Of 208 eligible biostatisticians (162 staff and 46 faculty), 69 (33.2%) responded. Among them, 44 (63.8%) reported using LLMs; of the 43 who answered the frequency question, 20 (46.5%) used them daily and 16 (37.2%) weekly. LLMs improved productivity in coding, writing, and literature review; however, 29 of 41 respondents (70.7%) reported significant errors, including incorrect code, statistical misinterpretations, and hallucinated functions. Key verification strategies included expertise, external validation, debugging, and manual inspection. Among 58 respondents providing training feedback, 44 (75.9%) requested case studies, 40 (69.0%) sought interactive tutorials, and 37 (63.8%) desired structured training. Conclusions: LLM usage is notable among respondents at two academic medical centers, though response patterns likely reflect early adopters. While LLMs enhance productivity, challenges like errors and reliability concerns highlight the need for verification strategies and systematic validation. The strong interest in training underscores the need for structured guidance. As an initial step, we propose eight core principles for responsible LLM integration, offering a preliminary framework for structured usage, validation, and ethical considerations.

TL;DR
This cross-sectional survey of biostatisticians at two academic medical centers found substantial LLM use, especially for coding, writing, and communication, alongside frequent concerns about errors and reliability. The authors propose eight principles for responsible LLM integration and highlight strong demand for structured training and verification guidance.
Key findings
- Among 208 eligible biostatisticians, 69 (33.2%) responded; 44/69 (63.8%) reported using LLMs, and among 43 who answered the frequency question, 20 (46.5%) used them daily and 16 (37.2%) weekly.
- LLM use was highest for “writing, debugging, or documenting code” (31/40, 77.5%), followed by “editing and improving writing quality” (29/38, 76.3%) and “composing emails or other messages” (27/38, 71.1%).
- Among 41 users answering about errors, 29 (70.7%) encountered incorrect answers that could have had significant consequences, including incorrect code, statistical misinterpretation, content fabrication, and inappropriate tone.
- Among 58 respondents providing training feedback, 44 (75.9%) requested case studies, 40 (69.0%) interactive tutorials, and 37 (63.8%) structured training; the paper proposes eight core principles for responsible LLM use.
Methods
- Cross-sectional survey conducted in September and October 2024 across three biostatistics units at Duke University School of Medicine and Stanford University School of Medicine; eligible population was 208 biostatisticians (162 staff, 46 faculty), administered via Qualtrics.
- Survey assessed LLM use across three core competency domains: communication and leadership, clinical and domain knowledge, and quantitative expertise, with branching logic for non-users.
- Quantitative analysis used frequency tables with counts and percentages in R/RStudio; free-text responses underwent thematic analysis combining human coding with ChatGPT-4o and Claude 3.5 Sonnet, plus word frequency analysis using R’s tidytext package.
Limitations
- The paper states a low response rate of 33.2% raises response bias concerns, likely reflecting early adopters; the sample from two academic medical centers with established biostatistics groups may not generalize to all biostatistical practice settings.
- The paper states reliance on self-reported interactions rather than direct analysis of LLM use, no systematic analysis of how different LLM models responded to the same statistical queries, and a focus on text-based LLMs rather than broader generative AI.
- The paper notes rapid LLM advancements during the study and manuscript preparation period (September 2024–February 2025) may limit applicability; the table also notes the organizational support question was implemented as single-select though intended as multiple-select, which may undercount reported support.

Data scientists follow similar interaction patterns to biostatisticians.
“While data scientists follow similar interaction patterns, Chopra et al. [25] found that practitioners spend significant time on prompt preparation and validation”

Section 4.1.2 (p. 8) reports that participants spent 64% of the measured time preparing prompts, but only the remaining 9%—24 seconds on average—validating code. Section 4.3.3 says validation took the least time of the activities measured, so describing time spent on both preparation and validation as significant overstates the validation finding. The comparison with biostatisticians is framing outside the claim attached to this citation. (LLM, conf=0.84)

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 2026-10-29.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-29.
Cited sources are checked by gpt-6-sol.
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.
