The Diabetes Detection Initiative: a pilot program of selective screening.

To identify adults who might have undiagnosed type 2 diabetes.Using social marketing methods, we identified the characteristics and preferences of the pilot communities. Risk assessment tests were developed to reflect these preferences. Clinics with registries provided quantitative evaluation data and all clinics shared qualitative data.Baseline and intervention period data showed that the number of newly detected cases of diabetes increased by 11.5 per month for the 8 registry clinics.Findings have advanced our understanding of screening by identifying ways of improving the identification of undiagnosed diabetes.
