研究目的: |
本研究为随机对照试验,旨在评估人工智能辅助这一新型干预措施对临床医师鉴别诊断正确率的影响。研究对象为神经外科医师参与者,研究者将其随机分配至AI辅助组和非AI辅助组。AI辅助组在常规诊断资源基础上,额外获得由研究者依据标准化提示词工程输入DeepSeek-R1后生成的推理过程、相关疾病诊断结果及诊断依据等辅助信息;非AI辅助组仅使用常规诊断资源完成判断。研究主要比较两组医师在标准化病例任务中的Top 1诊断正确率差异,并进一步评价诊断时间、诊断质量评分、LLM幻觉发生率及使用体验。病例资料仅作为统一的标准化诊断任务材料,不作为本研究的受试者。本研究重点在于评价AI辅助干预对医师诊断决策效果的影响,而非评价某一诊断工具本身的敏感度、特异度或诊断效能。 |

Objectives of Study: |
This study is a randomized controlled trial designed to evaluate the effect of an artificial intelligence assistance intervention on clinicians’ diagnostic accuracy in differential diagnosis tasks. The study participants are neurosurgical physicians, who will be randomly assigned to an AI-assisted group or a non-AI-assisted group. In the AI-assisted group, physicians will receive conventional diagnostic resources plus supplementary information generated by DeepSeek-R1 based on standardized prompt engineering prepared by the investigators, including reasoning processes, candidate diagnoses, and supporting diagnostic rationales. Physicians in the non-AI-assisted group will complete the same tasks using conventional diagnostic resources only. The primary objective is to compare the Top 1 diagnostic accuracy between the two groups in standardized case-based tasks, with additional evaluation of diagnostic time, diagnostic quality score, LLM hallucination rate, and user experience. Case materials serve only as standardized task materials and are not considered study participants. The focus of this study is to assess the effect of an AI-assisted intervention on physicians’ diagnostic decision-making, rather than to evaluate the sensitivity, specificity, or intrinsic diagnostic performance of a diagnostic tool itself. |
