Abstract
To compare outcomes and measures of efficiency for hospitalized elderly adults managed by geriatricians with those managed by other physicians. Secondary data analysis using a system that integrates clinical and financial information for inpatient and outpatient services delivered throughout the University of Pittsburgh Medical Center (UPMC). Propensity scores were developed based on participant sociodemographic and clinical characteristics and used to match participants based on the attending physician's specialty (geriatrician, n = 701; nongeriatrician, n = 11,549). Multivariate analyses using generalized estimating equations methods were performed. Two UPMC hospitals in Pittsburgh, Pennsylvania. Patients aged 65 and older admitted in 2002 in a medical diagnosis-related group (DRG). Outcomes (inpatient mortality, 30-day mortality, readmission) and efficiency measures (length of stay, total costs, and surplus, which is the difference between hospital costs and payment received for an admission). Elderly adults managed by geriatricians were significantly older (P < .001) and more likely to be male (P < .001) and had more diagnoses (P < .001). Propensity scores successfully balanced characteristics managed by the two groups. Pat...Continue Reading
