Using Self-reports or Claims to Assess Disease Prevalence: It's Complicated.

ABSTRACT:

Background

Two common ways of measuring disease prevalence include: (1) using self-reported disease diagnosis from survey responses; and (2) using disease-specific diagnosis codes found in administrative data. Because they do not suffer from self-report biases, claims are often assumed to be more objective. However, it is not clear that claims always produce better prevalence estimates.

Objective

Conduct an assessment of discrepancies between self-report and claims-based measures for 2 diseases in the US elderly to investigate definition, selection, and measurement error issues which may help explain divergence between claims and self-report estimates of prevalence.

Data

Self-reported data from 3 sources are included: the Health and Retirement Study, the Medicare Curr
