Health Challenge Wales supports a series of voluntary sector-led projects focused on improving the health and wellbeing of key target groups in Wales. It covers projects as diverse as breast cancer care and healthy hospitals. Our evaluation is happening in partnership with the Centre for Health Economics at Swansea University. The project is using a logic model approach to defining outcomes and developing a set of common indicators for the programme. Evaluation training sessions are being provided for grant holders. Case studies, project level consultations, data review and economic analysis are all underway.
