What is the Association Between Clinically Diagnosed Psychiatric Illness and Total Joint Arthroplasty? A Systematic Review Evaluating Outcomes, Healthcare Use, and Patient-reported Outcome Measures.

Our systematic review found that individuals with psychiatric illness had an increased risk of postoperative complications, increased length of stay, higher costs, less frequent home discharge, and worse PROM scores after TJA. These findings encourage inclusion of comorbid psychiatric illness when risk-stratifying patients. Attention should focus on perioperative interventions to minimize the risk of thromboembolic events, anemia, bleeding, and respiratory complications as well as adequate pain management with drugs that do not exacerbate the likelihood of these adverse events to minimize emergency department visits and readmissions. Future studies are needed to compare patients with concomitant psychiatric illnesses such as depression and anxiety with patients with either diagnosis in isolation, instead of only comparing patients with concomitant diagnoses with patients without any psychiatric illnesses. Similarly, the results of targeted interventions such as cognitive behavioral therapy are needed to understand how orthopaedic surgeons might improve the quality of care for patients with a comorbid psychiatric illness.
