RESUMEN
OBJETIVO: Avaliar a adesão ao tratamento preventivo de asma persistente moderada e grave. MÉTODOS: Médicos de vários Estados do país foram contactados para selecionar asmáticos persistentes moderados ou graves, maiores de doze anos. Os pacientes receberam salmeterol/fluticasona 50/250 µg diskus durante 90 dias (sendo orientados a retornarem as embalagens ao final do estudo para conferência da dosagem total utilizada). Receberam telefonemas da equipe do estudo no início e ao final de 90 dias para que fosse avaliada a adesão. Foi considerado como aderente ao tratamento o asmático que utilizou no mínimo 85 por cento das doses prescritas. As variáveis estudadas foram sexo, idade, cor, estado civil, escolaridade, tabagismo atual, outras atopias, co-morbidades, gravidade da asma, uso de outras medicações e número de hospitalizações por asma. RESULTADOS: Foram incluídos 131 pacientes oriundos de quinze estados, com taxa geral de adesão de 51,9 por cento. Houve diferença significativa na adesão quanto à gravidade da asma (maior adesão nos casos graves; p = 0,02). Não houve diferença estatisticamente significativa nas demais variáveis. CONCLUSÃO: A taxa geral de adesão ao tratamento de manutenção da asma foi baixa.
OBJECTIVE: To determine the rate of compliance with preventive treatment of moderate and severe persistent asthma. METHODS: Physicians at various medical centers across the country were invited to nominate patients for participation in the study. Inclusion criteria were being over the age of 12 and presenting moderate or severe persistent asthma. Participating patients received salmeterol/fluticasone 50/250 µg by dry powder inhaler for 90 days and were instructed to return the empty packages at the end of the study as a means of determining the total quantity used. In order to evaluate compliance, a member of the research team contacted each patient via telephone at the study outset and again at the end of the 90-day study period. Asthma patients were considered compliant with the treatment if they used at least 85 percent of the prescribed dose. The following variables were studied: gender, age, race, marital status, years of schooling, smoking habits, other atopic conditions, comorbidities, asthma severity, use of other medication and number of hospital admissions for asthma. RESULTS: A total of 131 patients from fifteen states were included. The overall rate of compliance was found to be 51.9 percent. There was a significant difference in compliance in relation to asthma severity: compliance was greater among patients with severe persistent asthma than among those with moderate persistent asthma (p = 0.02). There were no statistically significant differences among any of the other variables. CONCLUSION: The overall rate of compliance with maintenance treatment of asthma was low.
