Background: A rubric-based intervention program was designed to reduce the risk of developing coronary artery disease (CAD) in patients with dyslipidemia, and the effectiveness of community pharmacist-led intervention using the program was evaluated. Methods: We conducted an open-label, multicenter, randomized controlled trial. Participants included patients with dyslipidemia on statin medication recruited from August 2020 to July 2021. The intervention group received instructions from community pharmacists using a rubric-based intervention program in addition to usual pharmacist care. Conversely, the control group only received the usual care. The primary outcome was the change in the Suita score at month 6, which was compared between the intervention and control groups. The secondary outcome was the change in the rubric score, which was compared between the post-intervention and baseline. Results: We analyzed 15 participants (mean age, 61.9 years), whose mean Suita score was 42.6. No significant difference was observed in the change in the Suita score between the two groups. However, in the intervention group, the post-intervention Suita score was significantly lower than the baseline (43.9 vs. 38.7, p = 0.01), and the CAD risk classification based on Suita score decreased from medium to low risk. The post-intervention rubric score increased significantly compared with the baseline (2.0 vs. 3.1, p < 0.01). Conclusion: The rubric was a useful tool in promoting behavior changes in patients. The community pharmacist-led intervention for patients with dyslipidemia using a rubric-based intervention program showed the possibility of reducing the risk of developing CAD.
