ABSTRACT

OBJETIVO: Avaliar se a versão em língua portuguesa do Asthma Control Questionnaire (ACQ, Questionário de Controle da Asma) é um instrumento válido para medir o controle da asma em pacientes adultos ambulatoriais no Brasil. MÉTODOS: Foram avaliados 278 pacientes ambulatoriais com diagnóstico de asma. Todos os pacientes, durante a primeira visita, responderam ao questionário, foram submetidos à espirometria e avaliados clinicamente por um médico para a caracterização do controle da doença. Foram analisadas as versões do questionário com 5, 6 e 7 questões, utilizando dois escores distintos (0,75 e 1,50) como pontos de corte. RESULTADOS: Dos 278 pacientes, 77 (27,7 por cento) tinham asma intermitente, 39 (14,0 por cento) asma persistente leve, 40 (14,4 por cento) asma persistente moderada e 122 (43,9 por cento) asma persistente grave. A sensibilidade do questionário para identificar asma não-controlada variou de 77 por cento a 99 por cento e a especificidade variou de 36 por cento a 84 por cento. O valor preditivo positivo variou de 73 por cento a 90 por cento, e o valor preditivo negativo variou de 67 por cento a 95 por cento. A razão de verossimilhança positiva variou de 1,55 a 4,81, e a razão de verossimilhança negativa variou de 0,03 a 0,27. Nas versões do ACQ com 5 e 6 questões, o coeficiente de correlação intraclasse foi de 0,92, e estas versões foram responsivas a mudanças no quadro clínico dos pacientes. CONCLUSÕES: O ACQ, nas suas três versões, teve boa capacidade de discriminar indivíduos com asma não-controlada daqueles com asma controlada. As versões com 5 e 6 questões apresentaram também boa reprodutibilidade e responsividade. Trata-se, portanto, de um instrumento válido para avaliação do controle da asma em pacientes adultos ambulatoriais no Brasil.


OBJECTIVE: To evaluate whether the Portuguese version of the Asthma Control Questionnaire (ACQ) is a valid instrument to measure asthma control in adult outpatients in Brazil. METHODS: We selected 278 outpatients diagnosed with asthma. All of the patients completed the questionnaire, underwent spirometry and were clinically evaluated by a physician in order to characterize the control of the disease in the first visit. The questionnaire was evaluated in three versions, with 5, 6 and 7 questions, respectively, and scores of 0.75 and 1.50 were used as cut-off points. RESULTS: Of the 278 patients, 77 (27.7 percent) had intermittent asthma, 39 (14.0 percent) had mild persistent asthma, 40 (14.4 percent) had moderate persistent asthma and 122 (43.9 percent) had severe persistent asthma. The sensitivity of ACQ to identify uncontrolled asthma ranged from 77 percent to 99 percent, and the specificity ranged from 36 percent to 84 percent. The positive predictive value ranged from 73 percent to 90 percent, and the negative predictive value ranged from 67 percent to 95 percent. The positive likelihood ratio ranged from 1.55 to 4.81, and the negative likelihood ratio ranged from 0.03 to 0.27. In the 5- and 6-question versions of the ACQ, the intraclass correlation coefficient was 0.92. These two versions were both responsive to clinical changes in the patients. CONCLUSIONS: All three versions of the ACQ satisfactorily discriminated between patients with uncontrolled asthma and those with controlled asthma. The 5- and 6-question versions also presented good reliability and responsiveness. Therefore, the ACQ is a valid tool for evaluating asthma control in adult outpatients in Brazil.

ABSTRACT

OBJETIVO: Estimar a proporção de pacientes asmáticos com percepção inadequada do controle dos sintomas e avaliar as características deste subgrupo. MÉTODOS: Estudo transversal no qual foram selecionados pacientes ambulatoriais consecutivos com asma leve, moderada ou grave, maiores de 12 anos. Os pacientes foram submetidos a exame clínico, avaliação de depressão e da percepção do controle da asma e exame de função pulmonar. Foram realizadas avaliação da concordância quanto ao controle dos sintomas de asma entre médicos e pacientes e comparação entre as características dos pacientes com percepção adequada e inadequada do controle da asma. RESULTADOS: A concordância entre médicos e pacientes quanto ao controle da asma foi baixa (índice kappa = 0,5). Dos 289 pacientes incluídos, 66 (23 por cento) apresentaram percepção inadequada do controle da asma. A análise preliminar univariada revelou que os pacientes com percepção inadequada eram mais idosos, tinham menor renda familiar e apresentavam asma de menor gravidade. A análise multivariada não modificou os resultados. Não houve diferença entre os grupos quanto a sexo, freqüência de pacientes alfabetizados, tempo de sintomas de asma, diagnóstico de rinite, freqüência de depressão, função pulmonar ou adesão ao tratamento. CONCLUSÕES: A freqüência de percepção inadequada do controle da doença em pacientes com asma é elevada, principalmente em pacientes idosos, com baixa renda familiar e asma de menor gravidade.


OBJECTIVE: To determine the proportion of asthma patients with poor perception of asthma control and to evaluate the characteristics of this subgroup. METHODS: A cross-sectional study in which consecutive outpatients (over the age of 12) with mild, moderate, or severe asthma were selected. The patients underwent clinical examination and pulmonary function tests, as well as being assessed for depression and perception of asthma control. The degree of concordance between patients and physicians regarding the perception of asthma control was determined. Patients with good perception of asthma control were compared, in terms of characteristics, with those presenting poor perception. RESULTS: The degree of concordance between patients and physicians regarding the perception of asthma control was low (kappa index = 0.5). Of the 289 patients included, 66 (23 percent) presented poor perception of asthma control. The preliminary univariate analysis revealed that the patients with poor perception of asthma control were older, had a lower income, and presented a lower degree of asthma severity. Those factors did not change in the multivariate analysis. There were no differences between the groups in terms of gender, frequency of having literate patients, duration of asthma symptoms, having been diagnosed with rhinitis, frequency of depression, pulmonary function, or treatment compliance. CONCLUSIONS: The incidence of poor perception of asthma control in asthma patients is high, especially in elderly patients with lower income and a lower degree of asthma severity.
