Retrospective Cohort Study Comparing Complications, Readmission, Transfusion, and Length of Stay of Patients Undergoing Simultaneous and Staged Bilateral Total Hip Arthroplasty.

Abstract：

OBJECTIVES:To determine whether the rates of postoperative complications, rate of readmission, cumulative transfusion volume, and length of stay (LOS) differ between simultaneous total hip arthroplasty (THA) and staged bilateral THA and to assess whether the length of the interval between staged procedures influences surgery outcome. METHODS:This was a retrospective cohort study comparing the rate of postoperative complications, readmission, cumulative transfusion volume, and LOS between simultaneous THA and staged bilateral THA in our hospital's registration database. The inclusion criteria is listed as follows: patients who underwent bilateral primary THA between January 2011 and January 2015 with minimum 3-month follow-up; simultaneous bilateral THA; staged bilateral THA; postoperative complications, readmission, cumulative transfusion volume, length of stay of the patients and the influence of the interval between stages of bilateral THA on the outcome above; and retrospective cohort study. Finally, a total of 1145 patients, including simultaneous bilateral THA in 863 patients (1726 hips) and staged bilateral THA in 282 patients (564 hips), were eligible for the present study. The patients were divided into three groups according to the interval time (≤30 days, 30-90 days, >90 days) between the two stages of bilateral THA and we compared postoperative complications, readmission rates, cumulative transfusion volume, and LOS for the three groups. All patients' medical records and outpatient notes were reviewed to extract preoperative data, perioperative complications, readmission, cumulative transfusion, and LOS. Preoperative information included patients' age, sex, diagnosis, body mass index, and American Society of Anesthesiologists (ASA) classification. Perioperative complications were sorted into two groups: (i) medical complications included cardiovascular, pulmonary, neurological, digestive, and urologic system complications, along with other miscellaneous issues; and (ii) surgical complications included dislocation, superficial wound infection, hematoma, deep periprosthetic joint infection, and nerve palsy. Patients who failed to come back to visit our hospital in the postoperative 3 months were followed up by telephone, at which point we inquired about any postoperative complications and readmission. RESULTS:Simultaneous THA was performed more often in younger men, and patients in the simultaneous group had fewer major medical complications (excluding venous thromboembolism), fewer surgical complications, and shorter hospital stays; however, patients in the simultaneous group were likelier to have a higher transfusion rate than patients in the staged group. Among patients in the staged group, there were no differences for differing time intervals, except that patients with a between-stage interval of ≤30 days required more blood transfusions. CONCLUSION:With careful patient assessment and selection, simultaneous bilateral THA is a safe procedure, and has lower rates of surgical and major medical complications than staged bilateral THA.
