Clinic- and Community-Based National Diabetes Prevention Programs in Los Angeles.

Clinics and community-based organizations (CBOs) are priority settings for implementing the evidence-based National Diabetes Prevention Program (DPP). Both program settings present theoretical advantages and disadvantages for engaging and helping populations most at risk for diabetes achieve lifestyle change goals. To date, few studies have compared implementation across them. The present study describes participant characteristics and lifestyle change outcomes across a sample of clinic- and community-based National DPPs which delivered services in Los Angeles during 2015 to 2018 (two clinics, two CBOs, combined n = 265 participants). Analyses examined participant gender, age, race/ethnicity, baseline body mass index, and program attributes such as screening method and language of instruction. Negative binomial regression models tested for differences in program attendance, mean weekly physical activity, and percent change in body weight by setting. Overall, participants were largely Hispanic/Latinx (81.51%) and female (90.19%). Programs operated by CBOs engaged other race/ethnic groups including Black participants more frequently than those operated by clinics (20.56% vs. 0%); the latter engaged more men (15.29% vs. 7.22%). Few participants in any setting met the National DPP's weight loss goal (clinic: 15.29%, CBO: 20.00%). Participating in a community-based program was initially associated with higher attendance and mean weekly physical activity, but associations were not significant after adjusting for covariates. Study results have practice implications for National DPP implementation and can help inform future efforts to scale and spread the program in Los Angeles and nationally.

Exploring Reimbursement Options for the National Diabetes Prevention Program: Lessons Learned From a Pilot Project in Los Angeles, 2014-2018.

CONTEXT: Although Medicare and several state Medicaid programs are beginning to cover the cost of delivering the National Diabetes Prevention Program (National DPP), little is known about the logistical challenges to establishing reimbursement options for these services. OBJECTIVE: To describe Los Angeles' experience working with payers to identify and establish reimbursement pathways for National DPP providers. DESIGN: A case study was conducted to identify regional options for covering the costs of the National DPP. SETTING: Los Angeles. PARTICIPANTS: A managed care organization along with selected National DPP providers (those that provide in-person and/or online services) participated in this regional pilot project. INTERVENTION: The Los Angeles County Department of Public Health explored and prototyped reimbursement options for the National DPP, using input from and participation by target health plans (payers) and program providers. MAIN OUTCOME MEASURE: The establishment of a regional reimbursement approach for the National DPP. RESULTS: Pilot project participants weighed the pros and cons of billing (Medicare/Medicaid)/reimbursing for program services directly, ultimately choosing to go with a third-party integrator that worked with payers to handle the administrative process of reimbursing program providers for their services. The integrator negotiated and obtained reimbursements on the behalf of the National DPP providers. CONCLUSIONS: Lessons from this case study suggest an emerging need to build further capacity among National DPP providers, as they are often community-based organizations that are not equipped to bill Medicare/Medicaid directly for services. A third-party integrator represents a viable approach for addressing this logistical issue.

Current practices, facilitators, and barriers experienced by program providers implementing the National Diabetes Prevention Program in Los Angeles County.

Individuals with prediabetes can lower their diabetes risk by participating in the National Diabetes Prevention Program (National DPP), an evidence-based, group lifestyle change program that is taught by a certified lifestyle coach. To date, studies have not explicitly compared National DPP implementation across multiple settings (i.e., types of organizations) to understand comparative setting advantages or challenges to engaging priority groups. The purpose of this study was to gain an in-depth understanding of: (a) the variation in National DPP implementation across clinic, community-based, and digital settings and (b) associated facilitators and barriers. The study focused on three core implementation domains: recruitment, retention, and data reporting. This study used a descriptive, qualitative approach to identify current practices, facilitators, and barriers to National DPP implementation by conducting semistructured key informant interviews in spring 2018 with 12 organizations delivering the National DPP in Los Angeles County. There was a general commonality between in-person settings (clinics and community-based), while the experiences of digital providers were relatively distinct. Recruitment and retention were widely described by all settings as labor- and time-intensive, while data reporting was seen as relatively less burdensome. All respondents reported using multiple recruitment strategies. Lifestyle coaches were seen as key to retention, and they spent substantial time engaging with participants outside of class, which often was not accounted for in program costs. Data reporting was easier for organizations that invested in sophisticated data management systems and had staff with sufficient data experience. This study advances knowledge around the translation of the National DPP in diverse settings in the nation's largest county and highlights opportunities for targeted, setting-specific support.

A Framework for Implementing the National Diabetes Prevention Program in Los Angeles County.

INTRODUCTION: Preventing type 2 diabetes is a public health priority in the United States. An estimated 86 million Americans aged 20 years or older have prediabetes, 90% of whom are unaware they have it. The National Diabetes Prevention Program (NDPP) has the potential to reduce the incidence of type 2 diabetes; however, little is known about the best way to institutionalize such a program in a jurisdiction with a racially/ethnically diverse population. The objective of this study was to develop a practice-grounded framework for implementing the NDPP in Los Angeles County. METHODS: In 2015, the Los Angeles County Department of Public Health (LACDPH) partnered with Ad Lucem Consulting to conduct a 3-stage formative assessment that consisted of 1) in-depth interviews with key informants representing community-based organizations to learn about their experiences implementing the NDPP and similar lifestyle-change programs and 2) 2 strategic planning sessions to obtain input and feedback from the Los Angeles County Diabetes Prevention Coalition. LACDPH identified core activities to increase identification of people with type 2 diabetes and referral and enrollment of eligible populations in the NDPP. RESULTS: We worked with LACDPH and key informants to develop a 3-pronged framework of core activities to implement NDPP: expanding outreach and education, improving health care referral systems and protocols, and increasing access to and insurance coverage for NDPP. The framework will use a diverse partner network to advance these strategies. CONCLUSION: The framework has the potential to identify people with prediabetes and to expand NDPP among priority populations in Los Angeles County and other large jurisdictions by using a diverse partner network.
