There are many components to consider when performing an annual asthma review. The Quality and Outcomes Framework (QOF) can help by prompting healthcare professionals to include such tasks as inhaler technique, peak flow and the Royal College of Physicians’ three questions (RCP3Q). However, these are only process measures. To perform a review adequately, it is important also to understand the more subtle aspects of asthma management in order to achieve the best outcomes for the patient. The ‘SIMPLES’ approach is one way in which this might be achieved (Ryan et al, 2013).
