研究目的: |
筛选全身麻醉下日间腹腔镜手术患者术后复合不良事件(血压异常、PONV、中重度疼痛需干预)的独立危险因素,构建多任务机器学习预测模型,验证其区分度(AUC≥0.75)、校准度(Brier score<0.1)及临床实用性(决策曲线分析DCA净获益>5%)。 |
||||||||||||||||||||||
|
Objectives of Study: |
To identify independent risk factors for composite postoperative adverse events (blood pressure abnormalities, PONV, and moderate-to-severe pain requiring intervention) in patients undergoing day-case laparoscopic surgery under general anesthesia, build a multi-task machine learning prediction model, and validate its discrimination (AUC ≥ 0.75), calibration (Brier score < 0.1), and clinical utility (decision curve analysis net benefit > 5%). |
