[Identifying improvement opportunities in the management of hepatitis C]. / Identificación de oportunidades de mejora del tratamiento de la hepatitis C.

ABSTRACT

OBJECTIVE: Hepatitis C represents a public health concern with more than 170 million carriers. The goal of this study was to identify improvement opportunities in the management of hepatitis C, and the pharmaceutical actions performed for the prevention and solution of medication-related problems in patients seen at the Pharmaceutical Care Outpatient Unit. METHOD: A longitudinal study (January to October 2005) with patients monoinfected by hepatitis C virus receiving ribavirin and peginterferon alfa (2a or 2b). Data collection took place during the interview at the time of antiviral dispensation. Adverse reactions were classified according to CTCEA v3.0 criteria. Iaser methodology was used to identify patients with improvement opportunities regarding treatment. RESULTS: In all 109 patients and 201 improvement opportunities were identified. Pharmacotherapeutic morbidity was identified from adverse events (blood toxicity, pseudoflu syndrome, etc.) in 425 occasions; 388 pharmaceutical actions were performed, 41.23% to prevent adverse effects and 39.95% to provide patients or carers with information. CONCLUSIONS: In all, 99.01% of patients had safety problems. Pharmacotherapeutic morbidity from adverse effects was less common than reported in clinical trials of these drugs. Most pharmaceutical actions were preventive in nature. Iaser methodology allows to identify patients with improvement opportunities regarding hepatitis C treatment and the prevention of pharmacotherapeutic morbidity.
