HPH. ParkScripps Research Institute SKS.J. KimInje University GKGaeun Kim

Key Points

Public concerns regarding tuberculosis treatment include management challenges and social implications.
Most questions focused on rifampin and isoniazid, with hepatotoxicity and vomiting as common side effects.
Analysis using large language models outperformed traditional methods, providing cost-efficient insights.
Novel insights into blood donation and employment-related concerns were uncovered through social media data.

Abstract

Objectives: This study was conducted to investigate public perceptions and concerns surrounding tuberculosis (TB) treatment in Korea through an analysis of online queries about antitubercular medications. Additionally, it evaluated the effectiveness of large language models (LLMs) as analytical tools for processing unstructured healthcare data. Methods: Using LLMs, this study analyzed 44,174 questions that mentioned TB from Naver Knowledge-iN (2002–2024). Questions referencing antitubercular medications were extracted and thematically categorized. Side effects were analyzed through parallel approaches examining general and medication-specific effects. Questions about infectivity and social implications were further analyzed using text embedding, dimensionality reduction, and clustering. The performance of LLMs was evaluated against human researchers and traditional methods. Results: Among questions mentioning specific medications (n = 919), rifampin (31.8%) and isoniazid (31.6%) were most frequently referenced. Of the 10,044 questions regarding antitubercular medication, management challenges represented the largest category (44.8%). Analysis of infectivity and social implications (n = 583) revealed previously unidentified concerns about blood donation and immigration eligibility. Employment-related concerns constituted the largest distinct subgroup (20.6%). Hepatotoxicity, dermatosis, and vomiting were the most frequently reported side effects. LLMs outperformed keyword matching in data processing and offered cost advantages over human analysis, with finetuning further reducing processing costs. Conclusions: This study produced novel insights into public concerns regarding TB treatment and demonstrated the effectiveness of combining social media platform data with LLM-based analysis, providing a systematic framework for future healthcare research using unstructured public data and LLMs.
