Standardizing the definition of AMI using specific ICD codes in the primary diagnosis field is recommended to improve comparability across administrative database studies.
Standardizing AMI definitions via primary ICD codes enhances cross-study comparability; extends methodological consistency in administrative database research.
We recommend that ICD-9-CM 410 or ICD-10 I21-I22 in the primary diagnosis coding field should be used to define AMI. The use of a consistent validated case definition would improve comparability across studies.
