Cardiovascular disease (CVD) is the leading cause of disparities in years of life lost by race and low socioeconomic status. Statins have been shown to decrease the risk of cardiovascular events among individuals with high CVD risk. Yet, despite increased statin use and overall declining CVD rates, disparities in statin use and disparities in the control of high cholesterol by race, ethnicity, and socioeconomic status have persisted.

Objective: To improve the appropriate use of statins for primary cardiovascular disease prevention among high risk individuals at community health centers through a system of population health management that uses electronic health record (EHR) data to identify patients for targeted education and outreach.

Aim 1: Conduct a randomized controlled trial among individuals with 10-year risk for myocardial infarction or coronary death of 10% or higher to determine if the population health management intervention, compared to usual care, results in higher rates of documented statin treatment discussions within 6 months (primary process outcome), higher rates of statin prescribing within 6 months (secondary process outcome), and higher rates of significant low-density lipoprotein cholesterol (LDL-C) lowering defined as a follow up LDL-C ≥30 mg/dL lower than baseline (primary clinical outcome).

Aim 2: Interview patients who received the intervention to identify barriers to success

Aim 3: Assess the overall costs of the intervention and the costs per each patient who achieves significant LDL-C lowering compared to patient who received usual care.

Further study details as provided by Northwestern University:

Primary Outcome Measures:
  • Discussion between provider and patient about statin treatment [ Time Frame: within 6 months of randomization ] [ Designated as safety issue: No ]
    We will use queries of the electronic health record to detect documentation of face-to-face or telephone discussions regarding statin treatment. Physician investigators will be blinded to study group status and categorize variable as YES if there is documentation of any of the following in the chart (1) prescription for a statin (2) recommendation for statin therapy (3) patient refusal of statin (4) discussion of the use of a drug to lower cholesterol.

Secondary Outcome Measures:
  • Statin prescription [ Time Frame: within 6 months of randomization ] [ Designated as safety issue: No ]
    We will query the electronic health record to determine whether or not a statin was prescribed in the 6 months following randomization

  • Low-density lipoprotein cholesterol (LDL-C) [ Time Frame: within 1 year of randomization ] [ Designated as safety issue: No ]
    We will query the electronic health record to determine whether there was a significant lowering of LDL-C defined as a follow up LDL-C >= 30 mg/DL lower than baseline.

Arms Assigned Interventions
Experimental: Population Health Management Intervention
Participants randomized to this arm will receive the population health management intervention.
Behavioral: Population Health Management Intervention

This intervention includes:

  • Care manager led patient education to promote increased patient awareness of personal cardiovascular disease (CVD) risk and
  • Care manager led patient outreach to facilitate the treatment of eligible and appropriate patients with statins for primary CVD prevention
No Intervention: Usual Care Control Group
Participants randomized to this arm will receive usual care.
