Agreement between Medicare pharmacy claims, self-report, and medication inventory for assessing lipid-lowering medication use.

ABSTRACT:

Background

Medicare claims have been used to study lipid-lowering medication (LLM) use among US adults.

Methods

We analyzed the agreement between Medicare claims for LLM and LLM use indicated by self-report during a telephone interview and, separately, by a medication inventory performed during an in-home study visit upon enrollment into the REasons for Geographic And Racial Differences in Stroke (REGARDS) study. We included REGARDS participants ≥65 years enrolled in 2006-2007 with Medicare pharmacy benefits (Part D) from 120 days before their telephone interview through their medication inventory (n = 899).

Results

Overall, 39.2% and 39.5% of participants had a Medicare claim for an LLM within 120 days prior to their interview and medication inventory, respectively.
