Factors of U.S. Hospitals Associated with Improved Profit Margins: An Observational Study.

backgroundHospitals face financial pressure from decreased margins from Medicare and Medicaid and lower reimbursement from consolidating insurers.

objectivesThe objectives of this study are to determine whether hospitals that became more profitable increased revenues or decreased costs more and to examine characteristics associated with improved financial performance over time.

designThe design of this study is retrospective analyses of U.S. non-federal acute care hospitals between 2003 and 2013. SUBJECTS: There are 2824 hospitals as subjects of this study. MAIN MEASURES: The main measures of this study are the change in clinical operating margin, change in revenues per bed, and change in expenses per bed between 2003 and 2013. KEY

resultsHospitals that became more profitable had a larger magnitude of increases in revenue per bed (about $113,000 per year [95% confidence interval: $93,132 to $133,401]) than of decreases in costs per bed (about - $10,000 per year [95% confidence interval: - $28,956 to $9617]), largely driven by higher non-Medicare reimbursement. Hospitals that improved their margins were larger or joined a hospital system. Not-for-profit status was associated with increases in operating margin, while rural status and having a larger share of Medicare patients were associated with decreases in operating margin. There was no association between improved hospital profitability and changes in diagnosis related group weight, in number of profitable services, or in payer mix. Hospitals that became more profitable were more likely to increase their admissions per bed per year.

conclusionsDifferential price increases have led to improved margins for some hospitals over time. Where significant price increases are not possible, hospitals will have to become more efficient to maintain profitability.
