Integrated care interventions are extremely complex as they tend to invilve multiple actors and different care levels. When evaluating such programmes indicators provide several benefits in comparison with other approaches. The Agència de Qualitat Avaluació Sanitàries de Catalunya, through a new collaborative approach, has been working on the development of indicators specially aimed at assesing integrated care. The aim of this study was to present the methodology developed and review the evolution of the prioritized indicators in three different projects aimed at assessing chronic integrated care initiatives.
