1094-P: Attrition Rates among Participants in the National Diabetes Prevention Program: Variation by Organization Type, State, and Region

Abstract

The National Diabetes Prevention Program (National DPP) has been implemented nationwide, but it remains unclear how implementation varies by organization type, state, and region. To better understand this issue, we examined participant attrition rates using data from the CDC’s Diabetes Prevention Recognition Program. We included those who enrolled from March 2018 through February 2019 and had the opportunity to attend for at least one year in the study population. We limited our analyses to live-delivery organizations (i.e., in-person, distance learning, and combination) to minimize variation by delivery mode. Cumulative attrition rates were calculated by organization type (community centered entities, higher education/extensions, government, medical providers, for-profit and insurers, other), state, and region (West, Southwest, Midwest, Northeast, Southeast). We used cross-tabulation method with chi-square tests. The study population (N=70,194) was 80.8% female, 71.6% white, with a mean age of 55.4 years (SD: 13.0) and mean BMI of 35.5 kg/m2 (SD: 7.3). We found that for-profit and insurer organizations had significantly higher cumulative attrition rates compared to other organization types (through Session 5: 30.3% in for-profit and insurer organizations vs. 10.8%-17.4% in the other types, p<0.05). This pattern continued until Session 16 when similar attrition rates emerged from all organization types. Attrition rates across states also demonstrated large variations (through Session 5: highest (CA): 31.9% vs. lowest (ND): 2.2%, nation average: 17.9%). Northeast and West had higher attrition rates compared to the other three regions (through Session 5: 25.9% in Northeast and 22.6% in West vs. 8.7%-16.2% in the other three regions, p<0.05). Our findings can be used to evaluate program performance and help improve program implementation at the organization, state, and region levels. Disclosure X. Zhang: None. M. Cannon: None. B.
