Cost implications of self-management education intervention programmes in arthritis

The purpose of this review is to examine cost implications, including cost-effectiveness analyses, cost-savings calculated from health-care utilisation and intervention delivery costs of arthritis-related self-management education (SME) interventions. Methods: Literature searches, covering 1980-March 2012, using arthritis, self-management and cost-related terms, identified 487 articles; abstracts were reviewed to identify those with cost information. Results: Three formal cost-effectiveness analyses emerged; results were equivocal but analyses done from the societal perspective, including out-of-pocket and other indirect costs, were more promising. Eight studies of individual, group and telephone-delivered SME calculated cost-savings based on health-care utilisation changes. These studies had variable results but the costs-savings extrapolation methods are questionable. Meta-analyses of health-care utilisation changes in two specific SME interventions demonstrated only one significant result at 6 months, which did not persist at 12 months. Eleven studies reported intervention delivery costs ranging from $35 to $740 per participant; the variability is likely due to costing methods and differences in delivery mode. Conclusions: Economic analysis in arthritis-related SME is in its infancy; more robust economic evaluations are required to reach sound conclusions. The most common form of analysis used changes in health-care utilisation as a proxy for cost-savings: the results are less than compelling. However, other value metrics, including the value of SME as part of health systems' self-management support efforts, to population health (from improved self-efficacy, psychological well-being and physical activity), and to igniting patient activation, are all important to consider.
