Background:
Few studies have evaluated preoperative depression screenings in patients who have depression. We studied whether depression screenings before total knee arthroplasty (TKA) were associated with lower: 1) medical complications; 2) emergency department (ED) utilizations and readmissions; 3) implant complications; and 4) costs.
Methods:
A nationwide sample from January 1, 2010, to April 30, 2021, was collected using an insurance database. Depression patients were 1:1 propensity-score matched based on those who had (n = 29,009) and did not have (n = 29,009) preoperative depression screenings or psychotherapy visits within 3 months of TKA. A case-matched population who did not have depression was compared (n = 144,994). A 90-day period was used to compare complications and health-care utilization and 2-year follow-up for periprosthetic joint infections (PJIs) and implant survivorship. Costs were 90-day reimbursements. Logistic regression models computed odds ratios (ORs) of depression screening on dependent variables. P values less than .001 were significant.
Results:
Patients who did not receive preoperative screening were associated with higher medical complications (18.7 versus 5.2%, OR: 4.15, P < .0001) and ED utilizations (11.5 versus 3.2%, OR: 3.93, P < .0001) than depressed patients who received screening. Patients who had screening had lower medical complications (5.2 versus 5.9%, OR: 0.88, P < .0001) and ED utilizations compared to patients who did not have depression (3.2 versus 3.8%, OR: 0.87, P = .0001). Two-year PJI incidences (3.0 versus 1.3%, OR: 2.63, P < .0001) and TKA revisions (4.3 versus 2.1%, OR: 2.46, P < .0001) were greater in depression patients who were not screened preoperatively versus screened patients. Depression patients who had screening had lower PJIs (1.3 versus 1.8%, OR: 0.74, P < .0001) compared to nondepressed patients. Reimbursements ($13,949 versus $11,982; P < .0001) were higher in depression patients who did not have screening.
Conclusions:
Preoperative screening was associated with improved outcomes in depression patients.
