Source: AMI index events from January 1, 1997 to September 30, 2001 for beneficiaries enrolled in fee-for-service Medicare. Each hospital is weighted by the number of patients treated over the study period. Annual AMI Volume is the average number of patients aged 65 and over in the Medicare program admitted to the hospital for AMI. All differences across deciles are jointly significant at the p < .001 level
