Implementing treatment for chronic asthma Dr Claudia Gray MBChB, FRCPCH, MSc, PhD, Dip Allergy, DipPaedNutrition. Division of Allergology, Red Cross War Memorial Children’s Hospital and University of Cape Town Lung Institute 12 | May 2017 Avoidance of triggers, wherever possible, helps to minimise asthma severity and reduces asthma exacerbations. This includes avoidance of exposure to personal and second-hand tobacco smoke, reduction in exposure to furry animals, pollen, house dust mite and other allergens in those asthmatics known to be allergic, avoidance of sensitisers and irritants (dust and fumes) which aggravate or cause asthma, and avoidance of drugs that may aggravate asthma such as β blockers, aspirin and nonsteroidal anti- inflammatory drugs. Pharmacotherapy is the cornerstone of asthma management, with appropriate medications and delivery devices to meet patients’ needs and circumstances. When asthma is first diagnosed, it is convenient for implementation of treatment to classify it by SEVERITY as mild intermittent or chronic persistent asthma that is mild, moderate or severe. After therapy is initiated, the emphasis for clinical management changes to the assessment of asthma CONTROL, which is the degree to which the manifestations of asthma are minimised by therapeutic intervention and the goals of therapy are met.
