A matched-control study on the effects of depressive disorders following open reduction and internal fixation for acetabular fractures.

INTRODUCTION The World Health Organization (WHO) postulates that depressive disorders (DD) will be the leading cause of morbidity and mortality by 2030. Studies evaluating the association of DD following open reduction and internal fixation (ORIF) for the treatment of acetabular fractures are limited. Therefore, the purpose of this matched-control study was to determine whether DD patients undergoing ORIF for acetabular fractures have higher rates of: (1) in-hospital lengths of stay (LOS); (2) readmissions; (3) medical complications; and (4) costs of care. MATERIALS AND METHODS A retrospective query from the 100% Medicare Standard Analytical Files (SAF) was performed to identify patients who underwent ORIF for acetabular fractures. The study group consisted of those patients with DD, whereas patients without the condition served as controls. Primary endpoints of the study were to compare in-hospital LOS, readmission rates, ninety-day medical complications, and costs of care. A p-value less than 0.01 was considered statistically significant. RESULTS The query yielded 7084 patients within the study (ORIF = 1187, control = 5897). DD patients were found to have significantly longer in-hospital LOS (11 days vs. 10 days, p < 0.0001); however, odds (OR) of readmission rates were similar (23.16 vs. 18.68%; OR: 0.91, p = 0.26). Multivariate regression demonstrated DD to be associated with significantly higher (67.69 vs. 25.54%; OR: 2.64, p < 0.0001) 90-day medical complications. DD patients had significantly higher day of surgery ($30,505.93 vs. $28,424.85, p < 0.0001) and total global 90-day costs ($41,721.98 vs. $37,330.16, p < 0.0001) of care. CONCLUSION After adjusting for covariates, DD is associated with longer in-hospital, complications, and costs of care in patients undergoing ORIF for the treatment of acetabular fractures, whereas readmission rates are similar. The study is vital as it can be used by orthopaedists and healthcare professionals to adequately educate these patients of the potential outcomes following their surgical procedure.
