ABSTRACT
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. Our objecyive was to compare clinical outcomes between advanced practice clinician-based comanagement and usual orthopedic care. METHODS: This is a 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, intensive care unit (ICU) transfer, return to operating room, in-hospital 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 health care 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 (rate ratio = 0.95, P = .009), decreased odds of returning to the operating room (odds ratio [OR] 0.51, P = .002), and a significant reduction in 30-day mortality (OR 0.32, P = .037) compared with usual orthopedic care in a weighted analysis. Need for ICU transfer was higher with advanced practice clinician comanagement (OR 1.54, P = .009), without significant differences in 30-day readmission or in-hospital mortality. CONCLUSIONS: We observed reductions in length of stay, health care costs, return to the operating room, and 30-day mortality with advanced practice clinician comanagement compared with usual orthopedic care. Our findings suggest that advanced practice clinician-based comanagement may represent a safe and cost-effective model for orthopedic comanagement.
ABSTRACT
BACKGROUND: Academic medical centers have expanded their inpatient medicine services with advanced practice clinicians (APCs) or nonteaching hospitalists in response to patient volumes, residency work hour restrictions, and recently, COVID-19. Reports of clinical outcomes, cost, and resource utilization differ among inpatient team structures. OBJECTIVE: Directly compare outcomes among resident, APC, and solo hospitalist inpatient general medicine teams. DESIGN: Retrospective cohort study using multivariable analysis adjusted for time of admission, interhospital transfer, and comorbidities that compares clinical outcomes, cost, and resource utilization. SUBJECTS: Patients 18 years or older discharged from an inpatient medicine service between July 2015 and July 2018 (N = 12,716). MAIN MEASURES: Length of stay (LOS), 30-day readmission, inpatient mortality, normalized total direct cost, discharge time, and consultation utilization. KEY RESULTS: Resident teams admitted fewer patients at night (32.0%; P < .001) than did APC (49.5%) and hospitalist (48.6%) teams. APCs received nearly 4% more outside transfer patients (P = .015). Hospitalists discharged patients 26 minutes earlier than did residents (mean hours after midnight [95% CI], 14.58 [14.44-14.72] vs 15.02 [14.97-15.08]). Adjusted consult utilization was 15% higher for APCs (adjusted mean consults per admission [95% CI], 1.00 [0.96-1.03]) and 8% higher for residents (0.93 [0.90-0.95]) than it was for hospitalists (0.85 [0.80-0.90]). No differences in LOS, readmission, mortality, or cost were observed between the teams. CONCLUSION: We observed similar costs, LOS, 30-day readmission, and mortality among hospitalist, APC, and resident teams. Our results suggest clinical outcomes are not significantly affected by team structure. The addition of APC or hospitalist teams represent safe and effective alternatives to traditional inpatient resident teams.
