La falta de adherencia de los pacientes a sus tratamientos tiene un gran impacto tanto clínico como económico. Aunque existen diferentes métodos para medir la adherencia, los estudios retrospectivos son cada vez más utilizados por ser objetivos y menos sensibles a la percepción del paciente, interfiriendo menos en su vida. El sistema de receta electrónica proporciona a la farmacia comunitaria una herramienta útil para llevar a cabo esta investigación.
Utilizar el sistema de receta electrónica para medir la adherencia de los pacientes a su medicación crónica, analizando diferentes grupos terapéuticos y la salud mental de los pacientes.
Se desarrolló un estudio observacional, ambispectivo y longitudinal. La adherencia se evaluó mediante la Proportion of Days Covered (PDC) por paciente y por tratamiento y con el test de Morisky Green Levine. A través del sistema de receta electrónica se obtuvieron datos sobre los medicamentos dispensados a los pacientes durante los últimos 12 meses. Los datos sobre la salud mental de los pacientes se recogieron mediante el cuestionario PHQ-2.
Se reclutaron un total de 300 pacientes, pero sólo 290 se incluyeron en el análisis. El 25,5 % (IC: 20,6-30,9) se clasificó como polimedicado. El PDC por paciente tuvo una mediana de 0,90 (AI: 0,73-1). Según el cuestionario de Morisky Green Levine, el 57,9 % de los pacientes (IC: 52,0-63,6) eran adherentes a sus tratamientos. La concordancia entre el test de Morisky Green Levine y el PDC fue de kappa=0,086.
Patients` lack of adherence to pharmacological treatments has a major impact, both clinical and economical. While different methods are used to measure adherence, retrospective studies are being used more frequently as they are more objective, less prone to bias by patient perception and interfere less with patients’ lives. The electronic prescription system provides the community pharmacy with a useful tool to conduct this research.
To measure the adherence of patients to their chronic medication considering different therapeutic drug groups and their mental health using electronic prescription information available in a database.
An observational, ambispective and logitudinal study was developed for 300 patients. Adherence was assessed using Proportion of Days Covered (PDC) per patient and per treatment and the Morisky Green Levine test. Data on patients’ dispensed medication for the last 12 months was obtained through the electronic prescription system. Data on patient mental health was gathered using the PHQ-2 screen for depression.
A total of 300 patients were recruited, but only 290 were included in the analysis. 25.5%; [95%CI: 20.6:30.9] were classified as polymedicated. The median PDC per patient was 0.90 (IQR: 0.73 - 1). According to the Morisky Green Levine questionnaire, 57.9% of the patients [95%CI 52.0:63.6] adhered to their treatments. Concurrence between the Morisky Green Levine test and the PDC had a kappa k=0.086.
