Using large language models to assist qualitative thematic analysis of student reflections on advance care planning education.
Article in BMC medical education, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAdvance care planning (ACP) education has gained importance since Taiwan’s 2019 Patient Right to Autonomy Act, which empowers individuals to make advance medical decisions. Yet younger populations remain unfamiliar with ACP. This study examined how large language models (LLMs) can assist in qualitative thematic analysis of 1,761 reflection cards written by college students after an interactive ACP lecture.
methodsFour LLMs—GPT-4, Gemini Advanced 2.0, DeepSeek, and Claude 3.5 (Sonnet)—were each tested under two prompting conditions: a short generic instruction and a longer role-based prompt directing the model to act as a palliative care professor. The models inductively generated codes and themes without a predefined codebook. Their outputs were compared for thematic richness, interpretive depth, alignment with Braun and Clarke’s framework, and consistency with human-derived themes from reflexive thematic analysis.
resultsAll LLMs generated coherent thematic structures but differed in scope and depth. GPT-4 and Gemini produced concise, structured outputs closely resembling human analysis. DeepSeek provided narrative richness and cultural insight, emphasizing emotional and ethical dimensions. Claude 3.5 offered the most detailed categorization with frequency data and emotional tone analysis. Across models, recurring themes included understanding of ACP, family communication, life-and-death reflection, gratitude toward the lecture, and intentions to act.
conclusionLLMs demonstrated strong potential for conducting rapid and meaningful thematic analysis of qualitative data, identifying key educational and emotional patterns comparable to human analysis. They may serve as valuable adjuncts for large-scale qualitative research and medical education evaluation.
