Cost effectiveness of guideline advice for children with asthma: a literature review.
Asthma is an important chronic disease among children. This study reviews the cost effectiveness of interventions in the long-term care of asthmatic children and compares these results with treatment advice in four current guidelines. Cost-effectiveness studies were searched for in Medline, Embase, Healthstar, Biosis, and the Office of Health Economics-Health Economic Evaluations Database (OHE-HEED), and the Cochrane Library was searched for meta-analyses of clinical trials. In the four reviewed guidelines, cost effectiveness is not explicitly used as a criterion. The cost-effectiveness studies show sufficient evidence for the cost effectiveness of treatment with inhaled steroids and for self-management programs for severe asthmatic patients. Inclusion of these results in the guidelines would not lead to significant changes in current treatment advice. The effectiveness of various measures for trigger avoidance is not fully proven, and hence neither is their cost effectiveness. Available information on the cost effectiveness of cromolyn could be used to focus the guidelines. Finally, evidence exists that organizational interventions, e.g., the employment of asthma nurses, can result in cost savings, but it is unclear to what extent these results can be generalized. More cost-effectiveness studies are needed, especially on long-acting bronchodilators and self-management programs for mild and moderate asthma, in order to help make the guidelines more informative and reduce the differences between them.
