This measure assesses days spent in acute care within 30 days of discharge from an inpatient hospitalization for acute myocardial infarction (AMI) to provide a patient-centered assessment of the post-discharge period. This measure is intended to capture the quality of care transitions provided to discharged patients hospitalized with AMI by collectively measuring a set of adverse acute care outcomes that can occur post-discharge: emergency department (ED) visits, observation stays, and unplanned readmissions at any time during the 30 days post-discharge. In order to aggregate all three events, we measure each in terms of days. The Centers for Medicare & Medicaid Services (CMS) annually reports the measure for patients who are 65 years or older, are enrolled in Medicare Fee-For-Service (FFS), and are hospitalized in non-federal short-term acute care hospitals (including Indian Health Service hospitals) and critical access hospitals.

The outcome of the measure is a count of the number of days the patient spends in acute care within 30 days of discharge from an eligible index AMI hospitalization. We define days in acute care as days spent in an ED, admitted to an observation unit, or admitted as an unplanned readmission for any cause to a short-term acute care hospital, within 30 days from the date of discharge from the index AMI hospitalization.
Additional details are provided in S.5 Numerator Details.

1.15 Denominator
The target population for this measure is Medicare FFS beneficiaries aged 65 years or older hospitalized at non-federal short-term acute care hospitals for an eligible AMI admission.
The cohort includes admissions for patients discharged from the hospital with a principal discharge diagnosis of AMI and with continuous 12 months Medicare enrollment prior to admission. CMS will publicly report the measure for those patients 65 years and older who are Medicare FFS beneficiaries admitted to non-federal short-term acute care hospitals.
Additional details are provided n S.7 Denominator Details.
