Preventing type 2 diabetes in Salford

Somebody using a blood glucose monitoring system.

What did we do?

As part of our preventing type 2 diabetes work we developed an award-winning telephone support service, with improvements recorded in three-quarters of patients.

How did we do it?

We worked with Salford Diabetes Care on an impaired glucose tolerance (IGT) care call project which aimed to delay or reduce the risk of people with IGT developing type 2 diabetes. IGT is a condition where patients have a blood glucose level that is above normal but not high enough for a diagnosis of diabetes.

Taking Salford Diabetes Care’s existing care call service, we developed and implemented a telephone-based lifestyle intervention, delivered by trained health advisors, for patients diagnosed with IGT. The IGT care call service developed evidence-based scripts to provide educational messages, specifically for people with IGT, offering them lifestyle advice by a dedicated health advisor. Rather than teaching patients in a directive manner, health advisors engage in motivational discussions with patients, identifying key areas of their lifestyle that can be improved such as weight loss and healthy eating.

Research shows that without lifestyle or medical intervention, about 50% of people with IGT will develop type 2 diabetes within five to ten years. Intensive lifestyle interventions, such as IGT care call, can reduce the risk of developing type 2 diabetes by up to 58% for people with IGT.

Key outputs and impacts

  • 75% of patients supported in this way lost weight and 65-75% of patients saw improvements in oral glucose tolerance tests, showing the positive effect of their lifestyle changes
  • The project has been nationally recognised. IGT care call won the Quality in Care (QiC) award for “Best Type 2 Diabetes Prevention Initiative” in 2011 and NICE regard the IGT project as an exemplar for the prevention of diabetes in its 2012 guidelines
  • NHS Salford Clinical Commissioning Group (CCG) has commissioned the service for all patients with IGT.

What next?

Building on our success, we’re now working with Hitachi, Salford Royal NHS Foundation Trust, NHS Salford CCG and NorthWest EHealth to engage with general practices across Salford as part of the CATFISH (Comparison of Active Treatments for Impaired Glucose Regulation) trial.
