Abstract Background Administration of phosphate binders can decrease serum phosphate levels and improve the prognosis of patients on dialysis. However, patients are often non-adherent to phosphate binder medication. Although community pharmacist-led education could be effective in the maintenance of adherence to phosphate binder medication, its impact has not been evaluated. Objective We aimed to evaluate the impact of community pharmacist-led intensive education focusing on phosphate binders for patients receiving haemodialysis. Setting The study comprising three phases (baseline phase, intervention phase, and follow-up phase) was conducted at the Yamauchi Pharmacy, Japan. Method Six pharmacists provided intensive education focusing on phosphate binders to patients receiving haemodialysis. As intensive education, a sheet containing checks for the remaining phosphate binders and information advising the patients on the use of the drugs was issued. Using the check sheet filled in by the patient, the pharmacists repeatedly provided education appropriate to the individual patient’s medication status and level of understanding to encourage the correct use of phosphate binders for 8 weeks (intervention phase). We investigated their serum phosphate levels from their medical records from 2 months before the start of intensive education (baseline phase) to 8 months after the end of the education (follow-up phase). Main outcome measure Serum phosphate levels in patients receiving haemodialysis after intensive education by community pharmacists. Results Fifty patients were enrolled in this study. During the intervention phase, serum phosphate levels in the patients with high and the highest serum phosphate level (6–7 mg/dL and ≥ 7 mg/dL, respectively) significantly decreased by 6.9% (P = 0.007) and 10.9% (P = 0.034), respectively. The levels remained below the baseline value throughout the follow-up phase in patients with the highest serum phosphate level. Conclusion Community pharmacist-led education focusing on phosphate binders affects short- and long-term management of serum phosphate levels in patients receiving haemodialysis, especially the patients whose levels were initially high.
