Abstract

Background: The purpose of this study was to analyze the post-operative complications following THA in organ transplant patients; and compare the outcome with general population undergoing THA. Methods and materials: In this retrospective study using the National Inpatient Sample (NIS) database, 813 cases of THA (both primary and revision THA) in organ transplant patients (OT) were reviewed. ICD-10 codes were used to assess post-operative variables including the length of stay, cost of care, medical and surgical complications among OT patients undergoing THA. A comparison of all these variables was made with the non-OT (NOT) control population. Results: Among 367,894 patients undergoing THR between 2016 and 2019 on NIS database, 813 were OT patients. There was significantly greater proportion of males in the OT group (p < 0.001). Patients in the OT group were also significantly younger (mean age: 61.08 ± 11.95 in OT versus 65.87 ± 11.39 years in NOT; p < 0.001). The OT group had significantly higher prevalence of anemia (p < 0.001), acute renal failure (ARF; p < 0.001), and transfusion rates (p < 0.001). The OT patients also had significantly greater dislocation rates (p = 0.010), wound dehiscence (p = 0.03) and deep surgical-site infections (SSI; p = 0.002). The mean length of hospital stay (3.55 ± 4.89 days in OT vs 2.32 ± 2.52 days in NOT; p < 0.001), cost of care ($82,567.89 ± 74,505.54 vs $66,845.18 ± 47,761.39 for OT and NOT groups, respectively; p < 0.001) and mortality (p = 0.04) were significantly greater in the OT population, as compared to controls. Conclusion: Organ transplant patients have significantly greater risk for developing post-operative complications like anemia, ARF, need for higher transfusion rates, prosthetic dislocations, wound dehiscence, and deep SSI following THA. The length of stay, total expenditure incurred and mortality were also higher in OT patients undergoing THA.
