CVD prevention • Dyslipidemia and anti-hypertensive pharmacotherapy reduce CVD morbidity and mortality • Treatment guidelines are available • Adherence and persistence to treatment is low
Hypertension • Canadian Heart Health Surveys: • 16% are treated and controlled • 23% are treated and not controlled • 19% are not treated and not controlled • 42% are unaware of their hypertension AJH 1997; 10:1097-1102
Dyslipidemia • Low persistence to lipid-lowering medication • Two-year adherence in elderly: • Recent acute coronary syndrome: 40% • Chronic coronary artery disease: 36% • Primary prevention: 25% JAMA 2002; 288:462-467 • US-Canadian study: • Persistence: 50% after 5 years • Adherence: 66% of the time JAMA 1998;279(18):1458-1462

Pharmaceutical care • Patient education • Evaluation of CVD risk • Development of a treatment plan • Patient follow-up Complex, time consuming, and therefore not easily implemented. The development of decision support tools for facilitating pharmaceutical care is important.
Objective Development of a Decision Aid for patients with hypertension and dyslipidemia
Development Developed by a panel of five researchers and clinicians Reviewed by experts in the field and linguistic specialist Pretest among patients with hypertension or dyslipidemia Pilot studies with pharmacists
Decision Aid Includes: 1) Booklet 2) Personal worksheet
Booklet Provides general information • CVD • Risk factors • Treatment options • Four steps decision-making strategy • Examples of patients
Booklet The language is adapted to a grade-six level
Booklet Provides general evidence-based information
Worksheet Provides personal information to apply the four step strategy
Step One: To evaluate current cardiovascular health
Step One: • Modifiable CVD risk factors
Step One: • Current CVD risk • CVD age
Step Two: To evaluate the benefits of lifestyle changes and medication
Step Two: Estimates of the potential changes in CVD risk with lifestyle changes and medication Lifestyle changes: LDL: 5% HDL: 5% BP (syst/dias): 10 / 5 mm Medication: LDL: 35% HDL: 10% BP (syst/dias): 15 / 10 mm
Step Two: Net reduction in CVD risk if all modifiable risk factors are modified
Step Two: Patient's preferences
Step Three: To define a plan of action for the next three months with their health professional
Step Four: To follow progress over time
Development and Preliminary Testing of a Patient Decision Aid to Assist Pharmaceutical Care in the Prevention of Cardiovascular Disease. L Lalonde, AM O'Connor, SA Grover, P Duguay, A Kayal, E Drake Pharmacotherapy, July 2004
Methods • Convenience sample of hypertensive and dyslipidemic patients from an hypertension clinic and CVD-prevention clinic. • Interviews before and after the decision aid
Participants knowledge p=0.001* p=0.014* p=0.016* * Wilcoxon signed-rank test
Perception of CVD risk Risk Category 10-year CVD Risk p = 0.031* p = 0.000* * McNemar test (exact versus inexact estimation)
Decisional Conflict p=0.027* p=0.012* p=0.028* p=0.011* p=0.007*

Objective • To assess the feasibility, relevance and clinical usefulness of using a decision aid or a simpler educational tool (personalized risk profile) to assist pharmaceutical care in community pharmacies.
Patients initiating anti-hypertensive or lipid-lowering medication(< 12 months) Randomisation Telephone interview Decision aid and pharmacist intervention Personal risk profile and pharmacist intervention Telephone interview 3-month follow-up Telephone interview
Personal RiskProfile • Risk factors identification • CVD risk estimate • Benefit of treatment
Patients sollicited by pharmacistsn = 42 Patients refused to participate (n = 10) Patients involved in another study (n = 1) Pharmacotherapy discontinued (n = 2) Never sent their medical information to the research nurse (n = 3) Pre-intervention interview n = 26 Intervention Post-intervention interview n = 24 3 month follow-up interview n = 23
Analysis • No differences were observed between the DA and the PRP groups. • We combined the results of patients in the DA and the PRP groups • We assessed the differences before and after the intervention.
