 The study aims to understand barriers and facilitators to enrolling and completing the National Diabetes Prevention Program, National DPP, among women, and provide recommendations for improvement. Semi-structured interviews were conducted with eligible women who declined or did not complete the program, as well as clinicians who treat eligible women. The study identified known barriers such as cost, time, and inconvenient locations, but also discovered previously undiscovered barriers including unmet expectations and facilitating referrals. Improved communication between clinicians, patients, and National DPP staff, more training for National DPP staff, better incentives to participation, and making the program more accessible through flexibility in time and or locations may improve enrollment and retention rates.
