The authors analyzed Medicare data for about 3,000 acute care hospitals, of which 59 percent were nonprofit, 25 percent were for-profit and 16 percent were public. After adjusting for cost of living and the types of patients served, they found that more than half of all facilities lost money on patient-care services. Rural hospitals, small hospitals and major teaching hospitals tended to lose more money than urban hospitals and larger ones.
