LLM 기반 프로그램을 이용한 요추 수술 전후 임상 설문지 자동 처리

초록

Study Design: A retrospective analysis. Objectives: To assess the efficacy of large language model (LLM)-based automation in processing clinical questionnaires and compare performance between ChatGPT and Claude. Summary of Literature Review: Although patient-reported outcome measures are crucial in spine surgery, manual processing remains time-consuming and error-prone. Recent LLM developments offer potential automation solutions. Materials and Methods: Fifty-six questionnaire sets (336 pages) were processed thrice using both ChatGPT and Claude. A Python program incorporating PDF preprocessing, optical character recognition processing, and LLM analysis was developed. The performance metrics included accuracy, processing time, token usage, and cost efficiency. Results: Claude showed higher accuracy (96.76%) than ChatGPT (86.54%). Both models processed questionnaires in approximately 27 seconds, compared to 85 seconds for manual entry. Claude used fewer tokens (16,568.8 vs. 18,331.4) but had higher costs ($0.056vs.$0.023 per questionnaire). High repeatability was observed (Claude: κ=0.97, ChatGPT: κ=0.86). Conclusions: LLM-based automation demonstrates significant potential for processing clinical questionnaires, offering substantial time savings and high accuracy. While manual verification remains necessary, the efficiency of LLMs suggests their viability for large-scale clinical research, particularly using the Claude model.
