Acute Myocardial Infarction (AMI) Excess Days in Acute Care (EDAC)

The acute myocardial infarction (AMI) excess days in acute care (EDAC) measure includes Medicare fee-for-service (FFS) beneficiaries aged 65 or older and assesses the number of days a patient spends in an emergency department, hospital observation unit, or hospital inpatient unit within 30 days after the date of discharge from hospitalization for AMI. CMS began publicly reporting the AMI EDAC measure in 2017.

AMI EDAC measure results will be updated annually. As part of ongoing measure surveillance, analyses that provide a comprehensive overview of national performance on the measure or investigate select hospital practices that may impact hospital performance will be conducted.
