Comments Detailed

A patient is said to have AMI with a most responsible diagnosis of AMI based on the ICD-9 code 410 or ICD-10 code I21. Further information on how this cohort was generated: The case-definition algorithm to identify patients with AMI links different databases at ICES DAD, ICES SDS and OHIP and is based on the most responsible diagnostic codes to indicate that a patient had an MI (ICD 9 code: 410, or ICD 10 code: I21). The administrative data case-definition algorithm for AMI has a sensitivity of 80%, a specificity of 98%, and a PPV of 70%.3
