Conceptualising equity in the impact evaluation of chronic disease management programmes: a capabilities approach.

ABSTRACT

Chronic diseases are highly important for the future level and distribution of health and well-being in western societies. Consequently, it seems pertinent to assess not only efficiency of chronic care but also its impact on health equity. However, operationalisation of health equity has proven a challenging task. Challenges include identifying a relevant and measurable evaluative space. Various schools of thought in health economics have identified different outcomes of interest for equity assessment, with capabilities as a proposed alternative to more conventional economic conceptualisations. The aim of this paper is to contribute to the conceptualisation of health equity evaluation in the context of chronic disease management. We do this by firstly introducing an equity enquiry framework incorporating the capabilities approach. Secondly, we demonstrate the application and relevance of this framework through a content analysis of equity-related principles and aims in national chronic disease management guidelines and the national diabetes action plan in Denmark. Finally, we discuss how conceptualisations of equity focused on capabilities may be used in evaluation by scoping relevant operationalisations. A promising way forward in the context of chronic care evaluation may emerge from a combination of concepts of capabilities developed in economics, health sciences and psychology.
