Standard cost-effectiveness methods and critical appraisal toolkits may not be adequate for complex interventions. We systematically reviewed and quality assessed cost-effectiveness studies of a complex intervention, propose a series of new questions to inform their critical appraisal and discuss how future research should be targeted to improve the methods. Reablement was used as an example of a complex intervention. Reablement is a multidisciplinary and multifactorial intervention to support people to relearn activities of daily living.
