RESUMO
OBJECTIVE: Compare clinical outcomes between advanced practice clinician-based comanagement and usual orthopedic care. BACKGROUND: Comanagement of orthopedic surgery patients by internal medicine hospitalists is associated with improvements in clinical outcomes including complications, length of stay, and cost. Clinical outcomes of orthopedic comanagement performed solely by internal medicine advanced practice clinicians have not been reported. METHODS: Retrospective cohort study in patients 18 years or older, hospitalized for orthopedic joint or spine surgery between May 1, 2014, and January 1, 2022. Outcomes assessed were length of stay, ICU transfer, return to operating room, inhospital and 30-day mortality, 30-day readmission, and total direct cost excluding surgical implants. Generalized boosted regression and propensity score weighting was used to compare clinical outcomes and healthcare cost between usual care and advanced practice clinician comanagement. RESULTS: Advanced practice clinician comanagement was associated with a 5% reduction in mean length of stay (RR=0.95, p=0.009), decreased odds of returning to the operating room (OR= 0.51, p=0.002), and a significant reduction in 30-day mortality (OR= 0.32, p=0.037) compared to usual orthopedic care in a weighted analysis. Need for ICU transfer was higher with advanced practice clinician comanagement (OR= 1.54, p=0.009), without significant differences in 30-day readmission or inhospital mortality. CONCLUSIONS: We observed reductions in length of stay, healthcare costs, return to the operating room, and 30-day mortality with advanced practice clinician comanagement compared to usual orthopedic care. Our findings suggest advanced practice clinician-based comanagement may represent a safe and cost-effective model for orthopedic comanagement.
