This social impact bond (SIB) aims to prevent or manage type 2 diabetes for more than 6,500 people in Devon. The lifestyle of each patient will be reviewed to support improved mental health and well-being. The services will benefit the health of up to 1400 people and will result in savings to future health and social care budgets. In the short term, the SIB is expected to generate up to £300,000 net savings to Devon Public Health and will start up with £1million social investment to cover initial costs.
