Implication

Reliance on ICD code 428 risks under-ascertainment of CHF hospitalizations; leaves open validation of supplementary identification strategies.

Does the use of ICD codes accurately identify hospitalizations for acute congestive heart failure compared to clinical documentation?

Population

5083 patients hospitalized for possible acute myocardial infarction, aortocoronary bypass surgery, percutaneous transluminal coronary angioplasty, and related revascularization procedures in the Corpus Christi Heart Project

Intervention

ICD-9-CM codes (specifically code 428 or an algorithm based on a series of ICD codes) to identify acute congestive heart failure

Comparator

Clinical validation standard (composite variable including the presence of physician diagnosed acute CHF or radiographic evidence of pulmonary edema)

Outcome

Validity of ICD codes (sensitivity, specificity, positive predictive value, negative predictive value, and undernumeration)

Reliance on standard ICD codes for congestive heart failure leads to significant under-recognition, missing approximately one-third of patients with clinical evidence of acute CHF.
