Objetivo: A morbidade associada à asma é elevada, principalmente nos países em desenvolvimento, e as falhas na adesão ao uso de corticóide inalatório contribuem para esta elevação. Este estudo objetiva comparar as taxas de adesão ao uso de beclometasona relatadas pelos responsáveis e as mensuradas pelos registros de dispensação farmacêutica do medicamento. Métodos:Foi realizado um estudo de coorte concorrente com duração de 12 meses, do qual participaram 106 crianças e adolescentes asmáticos, selecionados aleatoriamente. Através da regressão linear, as taxas de adesão relatadas pelos responsáveis e pelos registros de dispensação da farmácia do serviço foram correlacionadas, quadrimestralmente, a partir da admissão no estudo.Resultados: As taxas de adesão relatadas pelos pais e/ou responsáveis foram sempre superiores (p < 0,001) e apresentaram fraca correlação com aquelas mensuradas pelos registros de farmácia nos períodos estudados, quarto (r = 0,37) e 12º (r = 0,31) mês do seguimento. Conclusão:As taxas de adesão relatadas pelos pais foram superestimadas em todos os períodos do estudo. Crianças com asma deveriam ter suas taxas de adesão também monitoradas por outros métodos e, neste caso, os registros de farmácia foram efetivos em revelar as falhas na adesão. Dado ao seu baixo custo, esse método está indicado para a verificação dessas taxas.J Pediatr (Rio J). 2007;83(5):471-476:Asma, adesão, corticóide inalatório, beclometasona.Objective: There is elevated morbidity associated with asthma, particularly in developing countries, and failure to comply with inhaled corticosteroid treatment contributes to this morbidity. The objective of this study is to compare rates of compliance with beclomethasone treatment reported by parents or guardians with those measured by pharmacy dispensing records. Methods:A concurrent cohort study of 12 months' duration was carried out, enrolling 106 asthmatic children and adolescents, selected at random. Linear regression was used to compare rates of compliance reported by parents or guardians with the pharmacy dispensing records at the service, every 4 months after enrollment on the study. Results:Compliance rates reported by parents and/or guardians were always higher (p < 0.001) and exhibited a weak correlation with pharmacy records during the period studied; fourth (r = 0.37) and twelfth (r = 0.31) months of follow-up. Conclusions:The rates of compliance reported by parents were overestimated during all study periods. The compliance rates of children with asthma should also be monitored by other methods and, in this case, pharmacy records effectively revealed compliance failures. Given its low cost, this method is indicated for verification of these compliance rates. Artigo submetido em 08.05.07, aceito em 11.07.07. J Pediatr (Rio J)
