Population
Hospitalized patients evaluated for myocardial infarction in the Corpus Christi Heart Project
Comparison
Identification of myocardial infarction using… vs CCHP 'gold standard' based on chest pain…

Implication
ICD code 410 supports efficient MI ascertainment in administrative data; leaves open reliability across populations and time periods.
Structured PICO
Does ICD code 410 accurately identify hospital admissions for myocardial infarction compared to a clinical gold standard?
P
Population
Hospitalized patients evaluated for myocardial infarction in the Corpus Christi Heart Project
I
Intervention
Identification of myocardial infarction using ICD code 410
C
Comparator
CCHP 'gold standard' based on chest pain, electrocardiographic changes, and cardiac enzymes
O
Outcome
Validity of ICD code 410 (sensitivity, specificity, predictive values, and efficiency)
Using ICD code 410 to identify hospitalized MI cases provides a modestly biased overestimate of definite MIs but is an efficient alternative to expensive validation procedures.
