Unit of Analysis: Single admission
Denominator
Total mid-year population age 18 and older
Numerator
Cases that are new AMI events admitted to an acute care hospital, age 18 and older.
A new event is defined as a first-ever hospitalization for an AMI or a recurrent hospitalized AMI occurring more than 28 days after the admission for the previous event in the reference period.
Comments
This indicator includes all new hospitalized AMI events in the reference period, encompassing first-ever and recurrent AMIs. A person may have more than one AMI event in the reference period. AMI events not admitted to an acute care hospital and in-hospital AMIs are not included in this indicator.
Myocardial infarction is labelled as acute with a stated duration of four weeks (28 days) or less in ICD-10-CA and eight weeks or less in ICD-9/9-CM. Therefore, a 28-day period to define a new AMI event is applicable to the records coded in ICD-10-CA only.
