[Self-reported experience in patients treated with Hepatitis C direct acting antivirals]. / Experiencia autorreferida en pacientes tratados con antivirales directos frente al virus de la hepatitis C.

BACKGROUND AND OBJECTIVE: To learn about and analyze the self-reported treatment experience of HCV patients who started treatment with direct acting antivirals agents (DAA), at a real-time, proactive and integrated into the pharmaceutical care healthcare process, using a prospective questionnaire completed by patients as clinical tool. MATERIAL AND METHODS: Observational and cross-sectional study conducted between April (start of the National Strategic Plan) and December 2015 in the Outpatient Pharmacy Service. The questionnaire includes variables related to health related quality of life (HRQOL), adherence, adverse effects (AEs), satisfaction, and usefulness of the Pharmacy Service implemented training program. A descriptive analysis of all variables included in the study was conducted and the influence of different variables analyzed in the degree of adherence and HRQOL. The analysis of the differences was performed using chi-square test and simple logistic regression model for calculation of OR. We use SPSS version 20 program and statistical significance for values of p < 0.05 was considered. RESULTS: 155 of the 226 surveys returned, with a response rate of 68.6%. Referring to the HRQOL (evaluation of physical and emotional state), 38.7% of patients reports that their physical and emotional state is much better from the start of treatment. The presence of EA and worse global information of their disease was associated with worse physical and emotional state (p < 0.05). Reported adherence was 84.5% and the treatment was evaluated as very good or good by 87% of patients. 52.9% had no adverse effects related to the medication and the training process performed by the specialist pharmacist at the first visit 96.7% of patients assessed as very good or good. CONCLUSIONS: Self-reported experience acquired through direct and constant contact with patients provides information on important aspects of treatment. We believe that these tools should be incorporated into pharmaceutical care procedures as a way to maintain continuity in patients direct contact. They also induce patients to a self-assessment of various aspects of their own treatment, which can help achieve greater involvement in it and can contribute to achieve the maximum health outcome in pharmacotherapy.

Introducción y objetivo: Conocer y analizar la experiencia autorreferida del tratamiento de los pacientes VHC que iniciaron tratamiento con agentes antivirales directos (AAD), a tiempo real, de forma proactiva e integrada en el proceso asistencial de atención farmacéutica. Material y métodos: Estudio observacional y transversal desarrollado entre abril (inicio del Plan Estratégico Nacional) y diciembre de 2015 en la Consulta Externa del Servicio de Farmacia. Se utilizó como herramienta un cuestionario prospectivo cumplimentado por los pacientes donde se recogieron variables relacionadas con la calidad de vida vinculadas con la salud (CVRS), adherencia, efectos adversos (EA), satisfacción con el tratamiento, y valoración y utilidad del programa formativo implementado por el Servicio de Farmacia. Se realizó un análisis descriptivo de todas las variables incluidas en el estudio y se analizó la influencia de las diferentes variables en el grado de adherencia y CVRS. El análisis de las diferencias entre los dos grupos se realizó mediante el test de chi cuadrado y el cálculo de las OR con un modelo de regresión logística simple. Se utilizó el programa SPSS® versión 20, y se estableció una significación estadística para valores de p < 0,05. Resultados: Se recogieron155 encuestas de las 226 enviadas, tasa de respuesta del 68,6%.En referencia a la CVRS (valoración del estado físico y emocional), un 38,7% de los pacientes refieren que su estado físico y emocional es mucho mejor desde el inicio del tratamiento. La presencia de EA y una peor información global de su enfermedad se asoció con un peor estado físico y emocional (p < 0,05). La adherencia reportada fue del 84,5% y el tratamiento fue valorado como muy bueno o bueno por el 87% de los pacientes. Un 52,9% de los pacientes no tuvieron efectos adversos relacionados con la medicación y el proceso formativo realizado por el farmacéutico especialista en la primera consulta fue valorado por el 96,7% de los pacientes como muy bueno o bueno. Conclusiones: La experiencia autorreferida obtenida a través de un contacto directo y permanente con los pacientes permite obtener información sobre aspectos importantes del tratamiento. Creemos que estas herramientas deben incorporarse a los procedimientos de atención farmacéutica como una forma de mantener la continuidad. Además, inducen al paciente a una autoevaluación de diversos aspectos de su propio tratamiento, que pueden ayudar a conseguir una mayor implicación en el mismo y contribuir a conseguir el máximo resultado en salud posible de la farmacoterapia.

Cross-cultural Adaptation and Validation of the Medication Regimen Complexity Index Adapted to Spanish.

BACKGROUND: The most widely used validated instrument to assess the complexity of medication regimens is the Medication Regimen Complexity Index (MRCI). OBJECTIVE: This study aimed to translate, adapt, and validate a reliable version of the MRCI adapted to Spanish (MRCI-E). METHODS: The cross-cultural adaptation process consisted of an independent translation by 3 clinical pharmacists and a backtranslation by 2 native English speakers. A reliability analysis was conducted on 20 elderly randomly selected patients. Two clinical pharmacists calculated the MRCI-E from discharge treatments and 2 months later. For the validity analysis, the sample was augmented to 60 patients. Convergent validity was assessed by analyzing the correlation between the number of medications; discriminant validity was stratified by gender; and predictive validity was determined by analyzing the ability to predict readmission and mortality at 3 and 6 months. RESULTS: The MRCI-E retained the original structure of 3 sections. The reliability analysis demonstrated an excellent internal consistency (Cronbach's α=0.83), and the intraclass correlation coefficient exceeded 0.9 in all cases. The correlation coefficient with the number of medications was 0.883 ( P<0.001). No significant differences were found when stratified by gender (3.6; 95%CI=-2.9 to 10.2; P=0.27). Patients who were readmitted at 3 months had a higher MRCI-E score (10.7; 95%CI=4.4 to 17.2; P=0.001). The differences remained significant in patients readmitted at 6 months, but differences in mortality were not detected. CONCLUSIONS: The MRCI-E retains the reliability and validity of the original index and provides a suitable tool to assess the complexity of medication regimens in Spanish.
