Baron JE, Khazi ZM, Duchman KR, et al. - This study was attempted to assess the prevalence of preoperatively diagnosed psychiatric comorbidities and the effect of these comorbidities on the healthcare costs of ten common orthopaedic sports medicine procedures. Researchers examined a total of 226,402 patients (57.7% male) from 2007 to 2017q1. The study found a high prevalence of preoperatively diagnosed psychiatric comorbidities among patients undergoing orthopaedic sports medicine procedures. The results illustrated that presence of psychiatric comorbidities preoperatively was correlated with elevated postoperative costs following all investigated orthopaedic sports medicine procedures. Within the entire database, prevalence of ≥1 psychiatric comorbidity was 10.31% (reference) while it was 21.21% in those undergoing the 10 investigated procedures. Rotator cuff repair (28%), hip labral repair (26.3%) and meniscectomy/meniscus repair (25.0%%) were the procedures patients with psychiatric comorbidity had most frequently. Compared with the no psychiatric cohort, diagnosis of ≥1 psychiatric comorbidity was linked to higher health care costs for all 10 sports medicine procedures.
