To assess the effect of cost sharing, a framework for describing and evaluating cost-sharing programmes was constructed, followed by a comprehensive search of the international literature on the subject. The results indicated that cost sharing carries many potential advantages, one of which includes increased consumer attention to healthcare costs. However, proper design of cost-sharing programmes is necessary to mitigate regressivity and other common problems associated with many current programmes. These findings should help policy makers to understand and anticipate the effects of cost sharing, and to create innovative benefit design solutions that are targeted to promote health system goals.
