Unmet needs in adult asthma.
Guidelines have been developed to provide an objective framework for the effective management of asthma. They are based on a mix of sound clinical practice and evidence-based medicine. The aims of asthma management are to ensure that the patient is symptom free and living an unrestricted life with normal physical activity, lung function normalized as much as possible, using minimum therapy, that exacerbations are kept to a minimum and mortality is reduced or abolished. In practice, however, these aims are not being met. Thus, unmet needs exist in asthma and need to be addressed. One particular unmet need is poor delivery of asthma care. Undertreatment of asthma is common, especially in severe asthma. However, studies suggest that some patients with severe asthma do not respond to any available treatments. Many outcome measures have been used in asthma and different outcomes will ensue according to which outcome measure is chosen, which in turn depends on the population studied. Asthma is a heterogeneous disease and there is heterogeneity in the response to treatment. However, at present there are no means to determine which patients will be a responder or non-responder to a particular treatment. In clinical trials of potential new asthma treatment we need to target the patient population more carefully according to the selected outcome measure, which should reflect the patient's perspective.
