Direct Cost and Complications Associated With Total Joint Arthroplasty in Patients With Preoperative Anxiety and Depression

IntroductionThe outcome of total joint arthroplasty (TJA) may be affected by numerous factors including the mental health status of patients and the presence of psychological disorders Therefore, the present study was designed and conducted to determine the impact of concomitant psychiatric disorders on the hospitalization charges and complications in patients with preoperative depression or anxiety undergoing TJA.Materials and MethodsInternational Classification of Diseases, Ninth Revision, codes were used to identify perioperative complications in patients with and without concomitant diagnosis of depression or anxiety who underwent TJA at our institution during 2009. Hospitalization charges and complications were compared for patients with and without depression or anxiety undergoing TJA.ResultsRespectively, 12.7% and 6.4% of knee and the hip arthroplasty patients had concomitant depression or anxiety. In the knee but not the hip group, the charge was $3420 higher in patients with depression/anxiety (P < .001). Anxiety and depression and higher American Society of Anesthesiologists score were independent predictors of complications.DiscussionDepression or anxiety was a predictor of increased complications after TJA. Therefore, patients with depression or anxiety undergoing TJA need to be counselled appropriately, and all efforts need to be invested to minimize complications and the added cost in these patients.
