Recent educational interventions for improvement of asthma medication adherence

Poor adherence to asthma medication treatment is a dilemma as it decreases the chance of achieving and maintaining a proper asthma control. Another dilemma is that there seems to be a small range of functional interventions that enhance adherence to long-term medication treatments. The aim was to review the last five years of published educational interventions for improving adherence to asthma medication. Through systematic database searches 20 articles were identified, which matched the inclusion criteria and described educational interventions to improve asthma self-management including adherence. The current review showed that addressing unintentional non-adherence in terms of incorrect inhaler technique by recurrent education improved the technique among many patients, but not among all. Phoning patients, as a means to remove medication beliefs as adherence barriers, seemed to be an effective educational strategy, shown as increased adherence. Involving patients in treatment decisions and individualising or tailoring educational support also seemed to have favourable effect on adherence. To conclude, addressing specific adherence barriers such as poor inhaler technique or medication beliefs could favour adherence. To change adherence behavior, the current review proposes that educational adherence support should be a collaborative effort between the patient and the health-care professional based on each individual patient's needs and patient factors, including elements such as personality traits.
