OBJECTIVE: To describe methodological aspects of the household survey National Survey on Access, Use and Promotion of Rational Use of Medicines (PNAUM) related to sampling design and implementation, the actual obtained sample, instruments and fieldwork. METHODS: A cross-sectional, population-based study with probability sampling in three stages of the population living in households located in Brazilian urban areas. Fieldwork was carried out between September 2013 and February 2014. The data collection instrument included questions related to: information about households, residents and respondents ; chronic diseases and medicines used ; use of health services ; acute diseases and events treated with drugs ; use of contraceptives ; use of pharmacy services ; behaviors that may affect drug use ; package inserts and packaging ; lifestyle and health insurance. RESULTS: In total, 41,433 interviews were carried out in 20,404 households and 576 urban clusters corresponding to 586 census tracts distributed in the five Brazilian regions, according to eight domains defined by age and gender. CONCLUSIONS: The results of the survey may be used as a baseline for future studies aiming to assess the impact of government action on drug access and use. For local studies using a compatible method, PNAUM may serve as a reference point to evaluate variations in space and population. With a comprehensive evaluation of drug-related aspects, PNAUM is a major source of data for a variety of analyses to be carried out both at academic and government level. ; Brazilian Ministry of Health through the Secretariat of Science, Technology and Strategic Inputs - SCTIE [25000.111834/2] ; Programa de Pós-Graduação em Epidemiologia.

OBJETIVO Descrever aspectos metodológicos do inquérito domiciliar da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM) quanto ao desenho e implementação da amostragem e da amostra efetivamente obtida, seus instrumentos e implementação do campo. MÉTODOS Estudo transversal de base populacional com amostra probabilística em três estágios da população residente nos domicílios localizados na zona urbana do Brasil. O trabalho de campo foi desenvolvido entre setembro de 2013 e fevereiro de 2014. O instrumento de coleta de dados incluiu questões relativas a: informações do domicílio, dos moradores e dos entrevistados; doenças crônicas e medicamentos utilizados; uso de serviços de saúde; doenças e eventos agudos tratados com medicamentos; uso de contraceptivos; uso de serviços de farmácia; comportamentos que podem afetar o uso de medicamentos; bulas e embalagens; estilo de vida e planos de saúde. RESULTADOS Foram realizadas 41.433 entrevistas em 20.404 domicílios e 576 conglomerados que correspondem a 586 setores censitários distribuídos nas cinco regiões do Brasil, segundo oito domínios definidos por grupos de idade e sexo. CONCLUSÕES Os resultados obtidos no inquérito podem ser utilizados como uma linha de base para futuros estudos que pretendam avaliar o impacto de ações governamentais nas áreas de acesso e de utilização de medicamentos. Para estudos locais que venham a usar um método compatível, a PNAUM pode servir como ponto de referência para avaliação de variações do espaço e da população. Com ampla avaliação dos aspectos relacionados aos medicamentos, a PNAUM é uma grande fonte de dados para as mais variadas análises, que podem ser conduzidas tanto no meio acadêmico como no âmbito governamental. ; OBJECTIVE To describe methodological aspects of the household survey National Survey on Access, Use and Promotion of Rational Use of Medicines (PNAUM) related to sampling design and implementation, the actual obtained sample, instruments and fieldwork.
