Abstract

Background: To date, no meta-analysis of the relationship between hospital readmission after total joint arthroplasty (TJA) and preoperative depression has been conducted. Hence, this systematic review and meta-analysis aimed to evaluate the association of preoperative depression with the readmission rate following TJA.

Methods: We systematically searched MEDLINE, EMBASE, and Cochrane Library for studies published before March 28, 2021, which compared readmission rates in patients with or without preoperative depression who underwent TJA. The primary outcome was the relationship between preoperative depression and 30-day and 90-day readmission rates after TJA. We also performed surgery type subgroup analyses for total hip arthroplasty, total knee arthroplasty (TKA), total shoulder arthroplasty, and total ankle arthroplasty.

Results: We included 9 studies with 395,815 TJA cases, of which 49,402 were diagnosed with preoperative depression and 346,413 were not. In pooled TJA analysis, the 30-day and 90-day readmission rates were significantly higher in the depression group than in the no-depression group (odds ratio [OR] 1.86, 95% confidence interval [CI] 1.26-2.73, P = .002 and OR 1.27, 95% CI 1.14-1.43,; P < .001, respectively). In the subgroup analyses, the 90-day readmission rate was higher in the depression group than in the no-depression group after TKA (OR 1.28, 95% CI 1.15-1.42, P < .001). There were no differences in other surgery types.

Conclusion: Based on available evidence, preoperative depression increases the readmission rate after TJA, particularly TKA. As depression is a modifiable risk factor, screening for depression and referring patients for proper psychiatric management are important.

Level of evidence: Level III, meta-analysis.
