Excess days in acute care (EDAC) after hospitalisation for acute myocardial infarction (AMI)

Total number of days that individuals in the denominator spent in acute care within 30 days of discharge. The measure defines days in acute care as days spent in an ED setting, days spent in an observation unit, or days spent hospitalised during an unplanned readmission for any cause within 30 days from the date of discharge. The measure counts each ED treat-and-release visit as one half-day. The measure records observation stays in terms of hours

All Medicare FFS beneficiaries aged 65 years and older who are hospitalised with a principal discharge diagnosis of AMI. These Medicare FFS beneficiaries must have 12 months of continuous Medicare Part A and B enrolment prior to the AMI index admission.

The exclusions for this measure include patients: • without at least 30 days post-discharge enrolment in Medicare FFS • discharged against medical advice • admitted within 30 days of a prior index discharge • admitted and then discharged on the same day
