Identification of diabetes, heart disease, hypertension and stroke in mid‐ and older‐aged women: Comparing self‐report and administrative hospital data records

Abstract

Substantial agreement was found for diabetes, indicating accuracy of ascertainment using self-report or hospital data. Self-report data appears to be less accurate for heart disease and stroke. Hypertension was underestimated in hospital data. These findings have implications for epidemiological studies relying on self-report or administrative data.
