Anna Starling is a Policy Fellow at the Health Foundation (an independent charity committed to bringing about better health and health care for people in the UK). The Foundation has recently published a report called Some Assembly Required; Implementing New Models of Care which looks at the lessons being learnt by the vanguard sites in the new care models programme. As the author of the report Anna tells Ben about four of the key lessons that are emerging; from focussing on a specific population to having a shared understanding of the problem.
