Clinical reasoning using ChatGPT: Is it beyond credibility for physiotherapists use?

Abstract

BACKGROUND: Artificial Intelligence (AI) tools are gaining popularity in healthcare. OpenAI released ChatGPT on November 30, 2022. ChatGPT is a language model that comprehends and generates human language, providing instant data analysis and recommendations. This is particularly significant in the dynamic field of physiotherapy, where its integration has the potential to enhance healthcare efficiency. OBJECTIVES: This study aims to evaluate whether ChatGPT-3.5 (free version) provides consistent and accurate clinical responses, its ability to imitate human clinical reasoning in simple and complex scenarios, and its capability to produce a differential diagnosis. METHODS: Study 2 assessed ChatGPT's differential diagnostic ability using published case studies by 2 independent participants. The case reports consisted of one simple and one complex scenario. RESULTS: Study 1 underscored the variability in ChatGPT's responses, which ranged from comprehensive to concise. Notably, essential steps such as re-assessment and subjective examination were omitted in 30% and 40% of the responses, respectively. In Study 2, ChatGPT demonstrated its capability to develop evidence-based clinical reasoning, particularly evident in simple clinical scenarios. Question phrasing significantly impacted the generated answers. CONCLUSIONS: This study highlights the potential benefits of using ChatGPT in healthcare. It also provides a balanced perspective on ChatGPT's strengths and limitations and emphasizes the importance of using AI tools in a responsible and informed manner.
