Building on value-based health care: Towards a health system perspective.

A variety of methodologies have been developed to help health systems increase the 'value' created from their available resources. The urgency of creating value is heightened by population ageing, growth in people with complex morbidities, technology advancements, and increased citizen expectations. This study develops a policy framework that seeks to reconcile the various approaches towards value-based policies in health systems. The distinctive contribution is that we focus on the value created by the health system as a whole, including health promotion, thus moving from value-based health care towards a value-based health system perspective. We define health system value to be the contribution of the health system to societal wellbeing. We adopt a framework of five dimensions of value, embracing health improvement, health care responsiveness, financial protection, efficiency and equity, which we map onto a society's aggregate wellbeing. Actors within the health system make different contributions to value, and we argue that their perspectives can be aligned with a unifying concept of health system value. We provide examples of policy levers and highlight key actors and how they can promote certain aspects of health system value. We discuss advantages of value-based approach based on the notion of wellbeing and some practical obstacles to its implementation.
