Summary
This study examines the use of patient initiated discussions of blood pressure medication in the primary care setting. Additionally, this study examines different levels of patient incentive(s) to initiate discussions with providers including information only, information plus a financial incentive and reimbursement for 6 months of copay, and information/monetary incentive plus a reminder call prior to the index visit. Patient opinions about doctor/patient relationships will be assessed. Provider attitudes and prescribing behaviors will be analyzed as well.
Eligibility Criteria
Inclusion Criteria
The eligible population includes patients less than 80 years of age enrolled in primary care clinics at the study sites that meet the following additional inclusion criteria:
- No active prescription for a thiazide diuretic (or a medication that combines a thiazide and another agent (e.g., hydrochlorothiazide and triamterene)
- Prior diagnosis of hypertension, as documented in VA outpatient administrative files
- Two or more visits to a primary care clinic in the prior 12 months;
- Blood pressure above treatment goal at the two most recent VA outpatient clinic visits Above goal is defined as a systolic pressure >140 mmHg or diastolic pressure >90 mmHg. For diabetics above goal is defined as systolic pressure >130 mmHg or diastolic pressure >80 mmHg
- Blood pressure at goal (as defined above) during one of the last two outpatient clinic visits, but the patient is receiving a prescription for a calcium channel blocker (CCB)
Exclusion Criteria
Patients meeting the above inclusion criteria will be excluded for the following reasons:
- Documented allergy to thiazides or to sulfa agents
- Previously documented intolerance or adverse drug reaction to thiazide diuretics
- Active prescription for a loop diuretic agent (e.g. furosemide)
- Renal insufficiency, defined by a glomerular filtration rate less than 30 ml/min
- No serum creatinine in the past year (to permit calculation of a creatinine clearance)
- Prior history of hypokalemia or serum potassium less than 3.5 meq/l in the prior year
- Diagnosis of gout or active prescription for allopurinol
- Congestive heart failure (CHF) due to systolic dysfunction with a documented left ventricular ejection fraction 4 errors on the 10-item Pfeiffer Portable Mental Status Questionnaire82, administered during study intake)
