Comparison of Pharmacy Database Methods for Determining Prevalent Chronic Medication Use.

ABSTRACT:

Background

Pharmacy dispensing data are frequently used to identify prevalent medication use as a predictor or covariate in observational research studies. Although several methods have been proposed for using pharmacy dispensing data to identify prevalent medication use, little is known about their comparative performance.

Objectives
