Abstract
OBJECTIVES: This study sought to examine the associations of hospitalist and cardiologist care of patients with heart failure with outcomes and adherence to quality measures.
BACKGROUND: The hospitalist model of inpatient care has grown nationally, but its associations with quality of care and outcomes of patients hospitalized with heart failure are not known.
METHODS: We analyzed data from the Get With the Guidelines-Heart Failure registry linked to Medicare claims for 2005 through 2008. For each hospital, we calculated the percentage of heart failure hospitalizations for which a hospitalist was the attending physician. We examined outcomes and care quality for patients stratified by rates of hospitalist use. Using multivariable models, we estimated associations between hospital-level use of hospitalists and cardiologists and 30-day risk-adjusted outcomes and adherence to measures of quality care.
RESULTS: The analysis included 31,505 Medicare beneficiaries in 166 hospitals. Across hospitals, the use of hospitalists varied from 0% to 83%. After multivariable adjustment, a 10% increase in the use of hospitalists was associated with a slight increase in mortality (risk ratio: 1.03; 95% confidence interval [CI]: 1.00 to 1.06) and decrease in length of stay (0.09 days; 95% CI: 0.02 to 0.16). There was no association with 30-day readmission. Increased use of hospitalists in hospitals with high use of cardiologists was associated with improved defect-free adherence to a composite of heart failure performance measures (risk ratio: 1.03; 95% CI: 1.01 to 1.06).
CONCLUSIONS: Hospitalist care varied significantly across hospitals for heart failure admissions and was not associated with improved 30-day outcomes. Comanagement by hospitalists and cardiologists may help to improve adherence to some quality measures, but it remains unclear what care model improves 30-day clinical outcomes.
