Risk factors for prolonged hospital stay in patients undergoing primary total knee arthroplasty following enhanced recovery after surgery protocol
Objective:To investigate the risk factors for prolonged hospital stays in patients undergoing primary total knee arthroplasty (TKA) following the enhanced recovery after surgery (ERAS) protocol. Methods:A retrospective analysis was performed on the clinical data of 260 patients who underwent primary TKA with strict implementation of ERAS measures at Wuxi Ninth People's Hospital from January 2020 to December 2023. A hospital stay of ≥5 days was defined as prolonged. Among these patients,88 (33.8％) were categorized in the prolonged stay group,while 172 (66.2％) were in the normal stay group. Demographic information,comorbidities,medical history,and surgery indicators were recorded and compared between the two groups. Multivariate logistic regression analysis was used to identify the risk factors for prolonged hospital stays in TKA patients following the ERAS protocol. Results:There were no significant differences between the two groups in gender,age,body mass index,smoking history,preoperative American Society of Anesthesiologists grade,history of cardiac failure,history of cerebrovascular accident,or operating surgeon (all P>0.05). However,the prolonged stay group showed significantly lower preoperative hemoglobin levels,higher proportions of diabetes mellitus and history of ischemic heart disease (IHD),higher perioperative blood transfusion rates,and longer surgery durations compared to the normal stay group (all P<0.05). Multivariate logistic regression analysis revealed that age>70 years (odds ratio[OR]=2.517,95％ confidence interval[95％CI]:1.051-6.030,P=0.038),a history of IHD (OR=0.194,95％CI:0.022-0.793,P=0.047),and surgery duration>90 minutes (OR=2.230,95％CI:1.190-4.181,P=0.012) were risk factors for prolonged hospital stays in TKA patients following the ERAS protocol. Conclusions:Age>70 years,a history of IHD,and surgery duration>90 minutes are risk factors for prolonged hospital stays in patients undergoing primary TKA following the ERAS protocol.
