Study Description
Brief Summary:
Using a 4-arm, cluster-randomized controlled trial, the investigators will test the effectiveness of different behavioral economic interventions in increasing statin use and reducing LDL cholesterol among patients with poor cholesterol control who are at very high risk for CVD. The investigators will test these approaches among primary care physicians and their patients at very high risk of CVD at Geisinger Health System and University of Pennsylvania outpatient clinics.

Condition or disease Intervention/treatment
Cardiovascular Disease Behavioral: Behavioral Economic Intervention

Detailed Description:
Cardiovascular disease (CVD) is the leading cause of death in the United States. Despite strong evidence that reducing low-density lipoproteins (LDL) with statins successfully lowers CVD risk, physicians under-prescribe statins, physicians fail to intensify treatment when indicated, and more than 50% of patients stop taking statins within one year of first prescription, though such therapy typically should be life-long. In this study, we will test the effectiveness of different behavioral economic interventions in increasing statin use and reducing LDL cholesterol among patients with poor cholesterol control who are at very high risk for CVD. The application of conceptual approaches from behavioral economics offers considerable promise in advancing health and health care. Pay for performance initiatives represent one such potential application, but one in which incorporating the underlying psychology of decision makers has not generally been done, and experimental tests have not been conducted. We will test these approaches among primary care physicians and their patients at very high risk of CVD at Geisinger Health System and University of Pennsylvania outpatient clinics. Using a 4-arm, cluster-randomized controlled trial, we aim to answer these questions: [1] How does the provision of provider incentives compare to the provision of patient incentives, to a combination of patient and provider incentives, or to no incentives at all? [2] Are results sustained after incentives and other interventions are withdrawn? [3] How do these approaches compare in implementation, acceptability, cost, and cost-effectiveness?

Arms and Interventions

Arm Intervention/treatment
Active Comparator: Physician Incentives

(with adherence feedback)

Quarterly payments to physician combined based on patient achieving an LDL reduction of at least 10 mg/dl relative to baseline LDL or the last quarter's target LDL with daily patient statin adherence information made available.

Behavioral: Behavioral Economic Intervention
Various combinations of financial incentives to patients and providers.
Active Comparator: Patient Incentives

(with adherence feedback)

Quarterly payments to patient based on patient achieving an LDL reduction of at least 10 mg/dl relative to baseline LDL or the last quarter's target LDL.

Behavioral: Behavioral Economic Intervention
Various combinations of financial incentives to patients and providers.
Active Comparator: Physician and Patient Combined Incentives

(with adherence feedback)

Quarterly payments shared evenly by physician and patient based on patient achieving an LDL reduction of at least 10 mg/dl relative to baseline LDL or the last quarter's target LDL. Physicians will receive daily information about patients' statin adherence.

Behavioral: Behavioral Economic Intervention
Various combinations of financial incentives to patients and providers.
No Intervention: Usual Care


Outcome Measures

Primary Outcome Measures :
  1. Change in LDL From Baseline to 12 Months [ Time Frame: 12 months ]
    Change in LDL-C levels (mg/dL)


Secondary Outcome Measures :
  1. Change in LDL From Baseline to 15 Months [ Time Frame: 15 months ]
    Change in LDL-C levels (mg/dL) from baseline to 15 months

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Physicians: All primary care providers who have at least 5 patients who meet eligibility criteria will be eligible.
  • Patients: 10-year CVD risk of between 10-20% who do not have an LDL below 140 mg/dl or 10-year CVD risk of at least 20% (including those with preexisting CHD) who do not have an LDL below 120 mg/dl will be the primary inclusion criteria. We have chosen to include all patients meeting these inclusion criteria regardless of their reported adherence to statins, as there clearly is room for improvement in the LDL through a combination of physician and patient actions.

Exclusion Criteria:

  • Patients will be excluded if they have a known allergy or history of side effects to statins, will not or cannot give consent, or have a markedly shortened life expectancy (diagnosis of metastatic cancer, end-stage renal disease on dialysis, or dementia).
