Pilot Program to Improve Statin Adherence and Lower Cholesterol in Older Adults

Phase 1

Completed

• Conditions: Medication Adherence; Hypercholesterolemia

• Registration Number: NCT01227330
• Lead Sponsor: University of Missouri-Columbia

Brief Summary

The purpose of this study is to pilot test a behavioral medication adherence (MA) intervention compared to control condition in older adults with low adherence to medication for hypercholesterolemia.

Detailed Description

This study will answer the following primary research question:

1. What is the estimated effect size of a behavioral MA intervention on MA rates in older adults who are poorly adherent to statin medications?

The study will also explore the following secondary research questions:

2. What is the estimated effect size of a behavioral MA intervention on low-density lipoprotein cholesterol (LDL-C) levels in older adults?

3. What is the estimated effect size of a behavioral MA intervention on high-density lipoprotein cholesterol (HDL-C) levels in older adults?

4. What is the feasibility of successfully testing this intervention protocol in a population of older adults with low adherence to statin medications?
