The overall goal of this study was to implement and evaluate the effects of a systems-based and pharmacist-mediated program designed to improve adherence for patients with known coronary heart disease (CHD) to lipid-lowering pharmacologic therapy and of their physicians/nurse practitioners to the National Cholesterol Education Program Guidelines.

Primary Outcome Measures:
  • The primary outcome evaluated is the percentage of patients with a serum low-density lipoprotein cholesterol (LDL-C) level <70 mg/dl. [ Time Frame: One year ]

Secondary Outcome Measures:
  • Proportion of prescribed lipid-lowering medication taken by patients as measured by a continuous multiple-interval (CMA) measure of medication availability based on pharmacy records. [ Time Frame: One year ]

Enrollment: 689
Study Start Date: September 2000
Study Completion Date: May 2005

Arms Assigned Interventions
Experimental: 2 Behavioral: systems-based and pharmacist-mediated program
Patients in the SI were seen by a study pharmacists prior to discharge to establish a relationship with the patient, explain the pharmacist's role in the study, provide education about all discharge medications and a medication card listing all medications and their manner of use, and set the framework for the follow-up telephone calls. Patients received pharmacist-delivered adherence counseling telephone contacts that took place at two weeks following discharge, and at months 1, 3, 6, and 9 oriented towards assisting patients to remain adherent to prescribed lipid-lowering and other medications, and also towards ensuring that all patients were either documented to be at the LDL-C goal, or were assisted to reach the goal by facilitating the scheduling of repeat lipid measurement as needed and providing information, guidelines and prompts to the patient's physician or nurse practitioner.
Other Name: Patient-centered counseling

Detailed Description:
Patients were randomly assigned to a usual care condition which consisted of patients provided with usual care only, or to the Special Intervention (SI) condition. The intervention was implemented and coordinated by pharmacists, who utilized for tracking and communication the Lotus Notes®-based system that was developed for the project.
