Abstract
Background: Community pharmacy cardiovascular disease (CVD) primary
prevention interventions, led by pharmacists, are effective. However, the majority of
these have targeted single CVD risk factors and most have not adequately assessed
the impact of dietary and physical activity behaviour. A multidisciplinary and multi-
risk factor approach that involves collaboration between dietitians (dietary and
physical activity consultations) and pharmacists (pharmacological treatment) may
provide additional risk reduction benefits for participants.
Objective: To assess the feasibility of implementing a community pharmacy-based
CVD primary prevention programme using a multidisciplinary approach to motivate
lifestyle behaviour change in participants at risk of CVD. The primary outcome was
change in estimated five-year CVD risk.
Methods: A 16-week single cohort pre- and post-test study was undertaken in two
community pharmacies with twelve participants aged 40-74 years who had risk
factors associated with increased CVD. Participants received dietary and physical
activity advice at baseline and every four weeks by a student dietitian as well as
pharmacological management assessment at baseline, 16 weeks and as needed by a
pharmacist. Biochemical (blood lipids, blood pressure, HbA1c) and anthropometric
(body composition, weight, height, waist and hip circumference) measures were
compared at baseline, eight and 16 weeks. Behavioural measures (diet, physical
activity and medication use) were compared between baseline and 16 weeks.
Results: Eleven participants (68±5.2 years) completed the programme. Significant
reductions from baseline to 16 weeks were observed for mean systolic and
diastolic blood pressure (-5.47, p = 0.04 and -4.06mmHg, p = 0.01 respectively) and
mean total cholesterol reduced significantly from baseline to eight weeks,
(-0.43mmol/L; p = 0.005) but not between baseline and 16 weeks. The average diet
quality score significantly improved by 12.6% from 65.9 to 74.2 out of 100 during the
intervention period (p = 0.007). Other CVD risk factor measures showed a trend
towards improvement. Five-year CVD risk did not significantly improve.
Conclusions: Results are comparable to existing literature on interventions to reduce
CVD in the community pharmacy setting. Findings within this small cohort,
particularly the improvements seen in diet, support the inclusion of dietitians for the
primary prevention of CVD in community pharmacies. A larger scale, controlled
study will help in determining the extent of efficacy with this approach.
