Abstract

BACKGROUND:

Despite national efforts to improve cholesterol management for patients with coronary artery disease, many patients are not reaching recommended cholesterol target levels. We sought to determine whether a nurse-based educational intervention, designed to educate patients with confirmed coronary artery disease about personal low-density lipoprotein (LDL) cholesterol target levels and encourage partnership with physicians, could increase adherence with National Cholesterol Education Program target levels (LDL cholesterol level < or =100 mg/dL).

METHODS:

Patients hospitalized with confirmed coronary artery disease were randomized to undergo a nurse-based educational intervention (375 patients) or usual care (381 patients) for a 12-month period after hospitalization. The primary outcome was the proportion of patients at the LDL cholesterol target level 1 year after hospitalization. The secondary outcome was the proportion of patients with accurate knowledge of LDL cholesterol target levels.

RESULTS:

The groups were similar at baseline in demographic and clinical characteristics, percent at LDL cholesterol target level (43.9% and 41.1%, respectively), and percent with knowledge of LDL cholesterol target levels (both 5%). The proportion of patients at LDL cholesterol target levels at 1 year did not differ between the intervention (70.2%) and usual care group (67.4%, P =.46). At the conclusion of the trial, patient knowledge about LDL cholesterol target level was higher for the intervention group than the usual care group (19.6% and 6.7%, respectively, P =.001), but this was not associated with improved cholesterol management.

CONCLUSIONS:

Our nurse-based educational intervention did not result in a significant increase in the proportion of patients who reached target LDL cholesterol levels 1 year after hospitalization. Although the intervention improved patient knowledge of LDL cholesterol target levels, overall rates of LDL cholesterol knowledge remained low, and it was not associated with improved cholesterol management.
