Risk Factors of Failure to Discharge Before “Two Midnights” in Outpatient-Designated Total Hip Arthroplasty

This is the authors' abstract. We don't add key points for this paper.

The Centers for Medicare and Medicaid Services removed total hip arthroplasty (THA) from the inpatient-only list but continued to classify admissions as inpatient if they include two midnights, complicating care if an outpatient THA requires extended hospitalization. This study evaluates risk factors of patients undergoing outpatient-designated THA with a length of stay (LOS) ≥ 2 days.
