Halawi MJ, et al. - Authors investigated 863 participants to evaluate the consequence of psychological distress on hospital length of stay (LOS) in modern-day fast-track total joint arthroplasty (TJA). They observed 23%, the prevalence of psychological distress and the mean LOS of 2.44 days. They noticed younger cases with psychological distress and more expected to have depression, lower educational attainment, smoke tobacco, be Hispanic/Latino, live alone, and had higher rates of non-primary osteoarthritis. No discrepancies in the rates of in-hospital complications, 90-day emergency room (ER) visits or readmissions were reported. They overall concluded psychological distress, an independent predictor of increased hospitalization following a primary, unilateral THA, and TKA. They recommended the SF-12 MCS, a suitable screening tool to distinguish cases with poor mental health unsuitable for outpatient surgery.
