Systematic evaluation of postoperative mortality risk prediction model for elderly patients with hip fracture after surgery
Objective To systematically evaluate the performance of mortality risk prediction models for elderly patients with hip fracture after surgery.Methods A total of 8 databases including VIP,CNKI,Wanfang,CBM,PubMed,web of science,The Cochrane Library,and Embase were searched,and the search time was from incep-tion of the database to April 10,2023.The literature screening and data extraction were independently conducted by 2 researchers,and PROBAST evaluation tool was used to evaluate the quality of the literatures included the study.Results A total of 17 risk prediction models for postoperative death in elderly patients with hip fracture were estab-lished in the 14 included literatures,and the area under the receiver operating characteristic curve(AUC)or C-index of 16 models was in the range of 0.72-1.00.The overall applicability of the included studies was high,but the o-verall risk of bias was high.The predictors with the highest frequency in the prediction model were age,gender,al-bumin,and American Society of Anesthesiologists(ASA)score.Conclusion The prediction model of mortality risk after hip fracture surgery in the elderly has good prediction performance,but the quality is low and still in the devel-opment stage.Future research needs to improve the quality of the prediction model from the aspects of data analysis,data source,and performance evaluation.At the same time,internal and external validation is needed to test its clin-ical efficacy.
