If we find and treat people earlier, can we reduce the chance of them dying early
and/or suffering from heart attacks and strokes?

Aims • To evaluate the feasibility of stepwise screening
programs to identify individuals with undiagnosed diabetes
• To assess the feasibility of the delivery of intensive treatment of risk factors in people with screen detected diabetes
• To evaluate the effectiveness in primary care of early intensive treatment compared to routine care on cardiovascular outcomes

ADDITION-Plus study
• Does extra support given by lifestyle facilitators improves outcomes in individuals with diabetes?
• Results suggested that the facilitators did not appear to add to what patients and practitioners were already doing
• However, ADDITION-Plus participants reported that they appreciated the extra support
![Page 38: ADDITION-Cambridge Five year results...28 practices screening and intensive target driven management of risk factors 27 practices screening and routine care Assessment of CVD risk](https://reader033.vdocument.in/reader033/viewer/2022060811/608f86cbf174a7385f08835a/html5/thumbnails/38.jpg)
5. Conclusions
![Page 39: ADDITION-Cambridge Five year results...28 practices screening and intensive target driven management of risk factors 27 practices screening and routine care Assessment of CVD risk](https://reader033.vdocument.in/reader033/viewer/2022060811/608f86cbf174a7385f08835a/html5/thumbnails/39.jpg)
Conclusions
• The health status of ADDITION participants was improved five years after diagnosis e.g. there were important reductions in levels of blood pressure, cholesterol and blood glucose.
• Earlier diagnosis and treatment of diabetes
has contributed to lower than expected rates of heart attack and premature death, which is now similar to those in the general population.
