Causes,Risk Factors And Preventive Analysis Of Unplanned Readmission After Total Joint Arthroplasty

Objective : to analyze the causes,risk factors and prophylaxis of unplanned readmission in patients with total joint arthroplasty within 90 days of discharge.Methods : a retrospective analysis of 348 patients with ostarthritis undergoing TJA were performed in June 2016 to June 2018 in our hospital.These patients were assigned into readmission group and non-readmission group according to whether or not they had been readmitted within 90 days after discharge.By comparing the clinical data of two groups,related risk factors of readmission group were analyzed by multivariate logistic regression models and student's test.Finally,the panel assessed whether patients in theunplanned readmission group could be prevented.Results:the unplanned readmission rate of TJA within 90 days after discharge was 5.7 percent,mainly due to stiffness,dislocation,wound infection,etc.,of which 8 cases were preventable.The differences of BMI,CCI,pattern of payment and education levels between the two groups were statistically significant.The results of multivariate Logistic regression analysis indicated that BMI,CCI were risk factors for unplanned readmission within 90 days after discharge.Conclusion:the patients were screened and evaluated strictly before surgery,the treatment measures during and after surgery were optimized,and the postoperative rehabilitation training was guided correctly to better identify risk factors,reduce complications,and further reduce the rate of unplanned readmission.
