A novel approach to improve health status measurement in observational claims-based studies of cancer treatment and outcomes.

ABSTRACT:

Objectives

To develop and provide initial validation for amultivariate, claims-based prediction model for disability status (DS), a proxymeasure of performance status (PS), among older adults. The model was designed to augment information on health status at the point of cancer diagnosis in studies using insurance claims to examine cancer treatment and outcomes.

Materials and methods

We used data from the 2001–2005 Medicare Current Beneficiary Survey (MCBS), with observations randomly split into estimation and validation subsamples. We developed an algorithm linking self-reported functional status measures to a DS scale, a proxy for the Eastern Cooperative Oncology Group (ECOG) PS scale. The DS measure was dichotomized to focus on good [ECOG 0–2] versus poor [ECOG 3–4] PS. W
