Utilization of Critical Care Services Among Patients Undergoing Total Hip and Knee Arthroplasty: Epidemiology and Risk Factors

The authors sought to identify the incidence and risk factors for the use of critical care services among orthopedic patients and compare the characteristics and outcomes of patients who require critical care services to those who do not. The presence of pulmonary compromise was associated with the highest odds for the use of critical care services (OR 18.44 (16.55, 20.55)).
