GRP-056 Effect of Pharmaceutical Follow-Up in Patients with Secondary Hyperparathyroidism Treated with Cinacalcet

Abstract

Objectives: To assess the effect of pharmaceutical intervention in the identification of drug-related problems, to improve desired clinical outcomes, and to evaluate the effectiveness of cinacalcet in achieving clinical outcomes recommended by the KDOQI Clinical Guidelines. Method: Quasi-experimental pre-post intervention study. Patients with Secondary Hyperparathyroidism due to Chronic Kidney Disease, aged ≥18 years and under treatment with cinacalcet were recruited at the hospital outpatient pharmacy between 2007 and 2009. Dáder follow-up method and SMAQ and Moriski questionnaires were used to verify adherence at the first interview. Then, the pharmacist analyzed each case and designed an adequate intervention. Clinical parameters were consulted in the hospital laboratory data base. Results: Thirty four patients were included, 29 drug-related problems were found before pharmacist intervention, and among these, non-adherence was the most common (15). After the intervention, 9 drug-related problems remained, which means that 68.9% of them were resolved (P<0.001), reaching an adherence of 80%. Parathyroid hormone, calcium and calcium-phosphorus product serum levels decreased significantly after 3 months of treatment (P<0.001, <0.001 and 0.045, respectively), achieving the KDOQI Clinical Guideline recommendations. Conclusion: These results suggest that this simple and easy-to-apply intervention was effective in preventing and resolving drug-related problems in these patients. Moreover, it improved patient adherence and confirmed that cinacalcet treatment is effective for achieving the clinical outcomes recommended by KDOQI clinical guidelines. © 2010 SEFH.
