Evaluation and determinants of asthma control among adult patients with asthma attending the Johannesburg academic respiratory clinics: A cross-sectional study

<b>What the study adds.</b> This study adds to the data on asthma control and associated determinants in the adult population in South Africa (SA). Data are scarce, despite the known high prevalence of asthma in this population.<b>Implications of the findings.</b> The study outlines the fairly poor levels of asthma control in this population, even at a tertiary level. The outcomes reflected here provide motivation for further investigation into levels of asthma control in SA and in sub-Saharan Africa as a whole. This further investigation could ultimately impact on patient care and provide the basis of improved best practice for both patient and physician education.
