Incidence of and risk factors for delirium in elderly fracture patients
Abstract：Objective To study the risk factors for delirium by investigating its incidence in elderly fracture patients undergoing conservative treatment.Methods One hundred and fifty-two elderly fracture patients admitted to our hospital for conservative treatment from January 2012 to November 2016 were included in this study.Their baseline data and relevant examination data were recorded.Their delirium was assessed every 2 days after 30 days of fracture.The risk factors for delirium were analyzed.Results Delirium occurred in 62 (40.8％) and 88 (58.1％) out of the 152 patients within 10 days after fracture.Mixed delirium accounted for 46.8％.The occurrence of hypoactive delirium increased with the increasing time.Delirium usually occurred in rib and femur neck fracture patients.Multivariate logistic regression analysis showed that history of preoperative cerebral accidents,high ASA score,severe pain,SIRS status,high CRP level were the risk factors for delirium (OR=0.122,95％CI:0.017-0.887,P=0.038;OR=9.061,95％CI:1.484-55.340,P=0.017;OR=5.554,95％CI:1.630-18.922,P=0.006;OR=10.640,95％CI:1.401-80.822,P=0.022;OR=1.221,95％CI:1.047-1.425,P=0.011).Conclusion Delirium is a common complication of rib or femur neck fractures.Delirium usually occurs within 10 days after fracture.History of preoperative cerebral accidents,high ASA score,severe pain,SIRS status and high CRP level are the risk factors for delirium in elderly fracture patients.
