Trends in the Sensitivity, Positive Predictive Value, False-Positive Rate, and Comparability Ratio of Hospital Discharge Diagnosis Codes for Acute Myocardial Infarction in Four US Communities, 1987-2000
Key result
The sensitivity of ICD-9-CM code 410 for classifying acute myocardial infarction was significantly greater in men (0.65) than women (0.60) and in Whites (0.67) than Blacks (0.50).

Intervention
ICD-9-CM hospital discharge code 410 for acute myocardial infarction
C
Comparator
Event classification based on published Atherosclerosis Risk in Communities (ARIC) Study criteria
O
Outcome
Validity of discharge codes (sensitivity, positive predictive value, false-positive rate, and comparability ratio)
The validity of ICD-9-CM code 410 for identifying AMI is generally stable but varies significantly by sex and race, highlighting the need for validation in surveillance studies.
Cite This Study
Rosamond et al. (2004) conducted an observational in Acute Myocardial Infarction (n=154,836). ICD-9-CM hospital discharge code 410 vs. ARIC Study criteria was evaluated on Sensitivity of ICD-9-CM code 410 for classifying AMI. The sensitivity of ICD-9-CM code 410 for classifying acute myocardial infarction was significantly greater in men (0.65) than women (0.60) and in Whites (0.67) than Blacks (0.50).
