ABSTRACT
The scope of this article is to determine patients' knowledge about the medication they take. For this purpose, a cross-sectional, observational and descriptive study was conducted. Knowledge was measured by a valid and reliable questionnaire (CPM-PT-PT), given to the patients attending community pharmacies participating in the study, who had prescriptions for one or more drugs in the Lisbon Metropolitan Area. Knowledge was assessed in four dimensions: therapeutic objective, process of use, safety and maintenance of the medications that the patient takes. Thirty-five pharmacies participated, and 633 valid patients were obtained. Fully 82.5% (95% CI: 79.3% -85.3%) were uninformed about the nature of the drug they use. In all items, there was a high percentage of patients with incorrect knowledge, with emphasis on precautions (44.7%). The dimension that the patients were least aware of was "drug safety" (1.9%). Eight out of 10 patients in the population do not know what drug they use. The highest lack of correct information was with respect to the "safety" of the medication.
El objetivo do artículo es determinar el conocimiento de los pacientes sobre sus medicamentos. Estudio observacional descriptivo transversal. El conocimiento se midió mediante un cuestionario válido y fiable (CPM-PT-PT), a los pacientes que acudieron a las farmacias comunitarias participantes en el estudio solicitando uno o varios medicamentos en el Área Metropolitana de Lisboa. Se determinó el conocimiento en sus cuatro dimensiones: objetivo terapéutico, proceso de uso, seguridad y conservación de los medicamentos que el paciente utiliza. Participaron 35 farmacias, obteniéndose 633 pacientes válidos. El 82.5% (IC95%: 79,3%-85,3%) no conocen el medicamento que utilizan. En todos los ítems, hubo un alto porcentaje de pacientes con conocimiento incorrecto, destacando especialmente las precauciones (44,7%). La dimensión que menos conocen los pacientes fue la "seguridad del medicamento" (1,9%). 8 de cada 10 pacientes de la población no conocen el medicamento que utilizan. La mayor carencia de información correcta corresponde a la "seguridad" del medicamento.

O objetivo deste trabalho é realizar a adaptação intercultural do espanhol para português europeu do questionário para medir o grau do "Conocimiento del Paciente sobre sus Medicamentos" (CPM-ES-ES). Aplicou-se um método baseado em seis etapas: 1. Tradução para português; 2. Preparação da primeira versão de consenso em português; 3. Retroversão para espanhol; 4. Preparação da segunda versão (equivalência cultural) de consenso; 5. Realização do pré-teste; 6. Avaliação dos resultados globais. Propõe-se um questionário adaptado culturalmente em português europeu que mede o grau do "conhecimento do doente sobre os seus medicamentos". O pré-teste de confirmação obteve 100% de concordância com a segunda versão de Consenso corrigida após o pré-teste. A metodologia selecionada permitiu adaptar culturalmente a versão em espanhol do questionário CPM-ES-ES para uma versão em português. Estudos adicionais devem demonstrar a equivalência das propriedades psicométricas da tradução intercultural em português do questionário com a versão original.
The scope of this work is to conduct the cross-cultural adaptation from Spanish to European Portuguese of a questionnaire to measure the degree of "Patient Knowledge about their Medications" (CPM-ES-ES). A method based on six steps was applied: 1. Translation into Portuguese, 2. Elaboration of the first consensus version in Portuguese; 3.Back-translation into Spanish; 4. Elaboration of the second consensus version (cultural equivalency); 5. Conducting the pre-test; 6. Evaluation of the overall results. A cross-culturally adapted questionnaire in European Portuguese that measures the degree of "Patient Knowledge about their Medications" is proposed. The pre-test confirmation obtained 100% agreement with the corrected version of the second consensus version after pre-testing. The methodology selected made it possible to cross-culturally adapt the Spanish version of the CPM-ES-ES questionnaire to the Portuguese version. Further studies should demonstrate the equivalence of the psychometric properties of the cross-cultural translation into Portuguese with the original version.
