Why the study?
Do ICD9-CM and ICD-10 codes accurately identify acute myocardial infarction from electronic healthcare records?
Do ICD9-CM and ICD-10 codes accurately identify acute myocardial infarction from electronic healthcare records?
ICD9-CM and ICD-10 codes are reliable for identifying acute myocardial infarction in electronic healthcare records, though ICPC codes and free-text searches require optimization.
Supports reliable AMI identification via ICD codes in EHRs for audits and studies; confirms validity for both ICD-9-CM and ICD-10.
ICD9-CM and ICD-10 codes have good PPV in identifying AMI from EHRs; strategies are necessary to further optimise utility of ICPC codes and free-text search. Use of specific AMI disease codes in estimation of risk during drug exposure may lead to small but significant changes and at the expense of decreased precision.
