Abstract
OBJECTIVE: To evaluate an educational outreach among consumer-directed health plan (CDHP) enrollees on medication persistence and lower-cost generic substitution within four chronic medication therapies. STUDY SETTING: A cross-sectional analysis using pharmacy claims data from a national employer group that began offering a CDHP in 2006 and implemented an educational outreach to some CDHP enrollees in 2007 was used. METHODS: The intervention group was comprised of CDHP enrollees who received education outreach and was compared with CDHP enrollees without the educational outreach. Adjusted and unadjusted medication persistence and lower-cost generic substitutions were compared between groups. PRINCIPAL FINDINGS: There was no difference in medication persistence between groups. CDHP enrollees with the educational outreach were more likely to have converted to lower-cost generic alternative antihypertensive medication compared with CDHP enrollees without the educational outreach (OR(adj)=29.82, 95 percent CI=4.41-201.93). CONCLUSION: Educational outreach directed to CDHP enrollees was associated with increases in lower-cost generic alternatives with no change in patients' chronic medication use. However, considerable opportunity exists to assist CDHP enrollees in making sound health care decisions.
