BackgroundNon-adherence to treatment advice is a common phenomenon in asthma and may account for a significant proportion of the morbidity. Comprehensive care that includes asthma education, a written self-management plan and regular review has been shown to improve asthma outcomes, but the contribution of these components has not been established.ObjectivesTo determine whether the provision of a written asthma self-management plan increases adherence and improves outcome.Search StrategyWe carried out a search on the Cochrane Airways Group trials register. There was no language restriction. The search of the databases used the following terms: action plan OR self OR self-care OR self-manag* OR educ* AND adher* OR comply OR compli*. We contacted authors of included studies for any unpublished or on-going studies and bibliographies of all included studies and reviews were searched for further studies. The most recent search was carried out in May 2003.Selection CriteriaWe only considered randomised controlled trials (RCTs) in patients with asthma. Participants must have been assigned to receive an individualised written asthma management plan (symptom or peak flow based) about the actions required for regular asthma management and/or the actions to take in the event of an asthma exacerbation.Data Collection And AnalysisTwo reviewers independently assessed study quality and abstracted data.Main ResultsSeven trials met the inclusion criteria. The written management plans were either peak flow or symptom based, which were compared against each other or compared to no written management plan. Reported outcomes included: medication adherence, hospitalisation, emergency department visits, oral corticosteroid use, lung function, days lost from school/work, unscheduled doctor visits and respiratory tract infections. There was no consistent evidence that written plans produced better patient outcomes than no written plan. For some outcomes, there appeared to be an advantage of one type of plan over the other, but there was no consistency - one type of plan was not consistently more effective than another.Reviewers' ConclusionsThe available trials are too small and the results too few and inconsistent to form any firm conclusions as to the contribution of written self management plans in the known beneficial effects of a comprehensive asthma care programme.
