Barriers and Facilitators to Enrollment and Retention in the National Diabetes Prevention Program: Perspectives of Women and Clinicians Within a Health System

Background: More than 10% of US adults are living with type 2 diabetes. The Centers for Disease Control and Prevention established the National Diabetes Prevention Program (National DPP) in 2010 in an effort to delay or prevent this disease among individuals at high risk. Unfortunately, enrollment and retention rates are low. This qualitative study aims to understand barriers and facilitators to enrolling and completing the National DPP among women, and to provide recommendations for improvement. Methods: Semistructured interviews were conducted with the following: (1) women who were eligible for the National DPP, but declined to enroll (n=11); (2) women who enrolled in the National DPP, but did not complete the program (n=12); and (3) clinicians who treat women eligible for the National DPP (n=12). Transcripts of the interviews were coded using content analysis. Results: The 35 interviews (23 patients and 12 clinicians) provided further insight into known barriers, such as the cost of the program, the time that it takes, and inconvenient locations. The study also identified previously undiscovered barriers, including the program not meeting participants' expectations and facilitating referrals. Furthermore, improved communication between clinicians, patients, and National DPP staff could ensure that both clinicians and National DPP staff are aware of patients' goals and their individual barriers to success. Conclusions: Enrollment and retention in the National DPP may be improved with additional communication, more training for National DPP staff to work more closely with participants, adding better incentives to participation, and making the program more accessible through flexibility in time and/or locations.
