Implementation of a pharmaceutical care program for patients with hepatitis C treated with new direct-action antivirals

Background A pharmaceutical care program is necessary to improve the management of direct-acting antivirals in hepatitis C. Objective Describe health outcomes obtained with the implementation of a pharmaceutical care program in Hepatitis C patients treated with direct-acting antivirals. Setting This study was performed in a pharmacy department of a university hospital. Methods Retrospective study between 1st-April 2015 and 28st-February 2016. Hospital pharmacists implemented interventional measures for validation of antivirals prescriptions, detection of drug-interaction, adverse drug events, education and patient´s adherence to antiviral regimen. Main outcome measure Health and quality outcomes of the implementation of the pharmaceutical care program. Results A total 128 patients were enrolled. The overall sustained virologic response at week 12 post-treatment rate was 96.1% (95% CI 92.7–99.5). Adverse drug events occurred in 90.6% of the patients, and the majority were grade 1–2. Pharmacists made 334 pharmaceutical interventions. 35.5% of these interventions were aimed to resolve negative results of drugs. 80.9% of the negative results of drugs improved or were eliminated with the application of the measures proposed by the pharmacists (p ≤ 0.001). Pharmacists carried out 175 preventive interventions to avoid negative results of drugs. 97.3% of these interventions were accepted and managed to prevent the appearance of negative results of drugs (p = 0.453). Conclusion The implementation of a pharmaceutical care program in patients with hepatitis C treated with direct-acting antivirals has improved the safety in the use of these drugs.
