Adherencia al tratamiento en pacientes polimedicados mayores de 65 años con prescripción por principio activo / Adherence to treatment, by active ingredient, in patients over 65 years on multiple medication

OBJETIVO: Valorar el nivel de adherencia al tratamiento y los factores relacionados en polimedicados mayores de 65 con prescripción por principio activo. DISEÑO: Estudio observacional, descriptivo, transversal, sobre polimedicados mayores de 65 años adscritos a los centros de atención primaria del Distrito Sanitario Costa del Sol y del Área Sanitaria Norte de Málaga. Se ha realizado entre enero del 2011 y septiembre del 2012, sobre una población de 375 individuos obtenida mediante muestreo aleatorio simple a partir de las listas de pacientes proporcionadas por cada centro. Los datos se recogieron mediante entrevista, sobre hoja estructurada de recogida de datos y previa firma del consentimiento informado. Variables del estudio: Variable principal de resultado: adherencia al tratamiento (test de Morisky-Green). Variables predictoras: Prescripción por principio activo, variables sociodemográficas, clínicas y relacionadas con la medicación. Se efectuó un análisis descriptivo de las variables. La inferencia estadística se realizó mediante análisis bivariante (test de la t de Student o U de Mann Whitney y chi al cuadrado), controlándose los factores de confusión mediante análisis multivariante (regresión lineal y logística). RESULTADOS: El cumplimiento terapéutico se sitúa en el 51,7%, no apreciándose diferencias estadísticamente significativas con respecto al sexo o la edad. Encontramos relación con residir en zona de interior (p = 0,001), vivir acompañados (p < 0,05) y no presentar riesgo de ansiedad (p = 0,046). CONCLUSIONES: La adherencia es similar a los estudios realizados, independientemente de si la prescripción es por principio activo. El incumplimiento fue mayor en individuos que viven solos, en población costera y con riesgo de ansiedad

AIM: To assess the level of adherence, by active ingredient, to treatment and associated factors in polymedicated patients over 65 years-old. DESIGN: Observational, descriptive and cross-sectional study over polymedicated patients over 65 years of the Costa del Sol Health District and the North Malaga Health Area. The study was performed between January 2011 and September 2012 on 375 subjects obtained by simple random sampling from lists provided by each health centre. Data was collected by means of an interview with structured questions. Informed consent was given and signed by all patients before interview. Study variables: Main results variable adherence to treatment (Morisky-Green's test).Predictable variables: Prescription by active ingredient, socio-demographic variables, healthcare centre variables, and treatment associated variables. A descriptive analysis of variables was performed. Statistical inference was determined using univariate analysis (t test of Student or Mann-Whitney U, and Chi-squared), and controlling for confounding factors by multivariate analysis (linear and logistic regression). RESULTS: The result for therapeutic compliance was 51.7%. No statistically significant differences were observed as regards sex and age. A relationship was found in those who resided in rural areas (p = 0.001), lived with family (p < 0.05), and were not at risk of suffering from anxiety (p = 0.046). CONCLUSIONS: We found similar patient adherence to treatment despite the prescribing generic drugs. Failure to therapeutic compliance was greater in those patients who lived by themselves, in a city close to the coast, or in those patients who were at risk of suffering from anxiety

RESULTS: The result for therapeutic compliance was 51.7%. No statistically significant differences were observed as regards sex and age. A relationship was found in those who resided in rural areas (P=.001), lived with family (P<.05), and were not at risk of suffering from anxiety (P=.046). CONCLUSIONS: We found similar patient adherence to treatment despite the prescribing generic drugs. Failure to therapeutic compliance was greater in those patients who lived by themselves, in a city close to the coast, or in those patients who were at risk of suffering from anxiety.
