Effective recruitment for practice-based research: Lessons from the REAL HEALTH-Diabetes Study.

ABSTRACT: Background:Aims: The REAL HEALTH Diabetes Study is a practice-based randomized clinical trial that compares the effectiveness of lifestyle intervention aimed at weight reduction to medical nutrition therapy in primary care patients with type 2 diabetes. This paper describes a tiered approach to recruitment, the resultant enrollment rates of sequentially more intensive recruitment strategies, and identifies barriers to participation. Methods:Potential participants were identified using patient health registries and classified by recruitment site. Four recruitment strategies were used to achieve target enrollment: (1) mail/telephone outreach; (2) direct referral from providers; (3) orientation sessions; and (4) media/advertising. Reasons for ineligibility and non-participation were tracked. Results:Fifteen thousand two hundred sixty-nine (15,269) potential participants were identified from all sources, with the clear majority coming from patient registries. Mail/telephone outreach alone had the lowest enrollment rate (1.2%). Direct referral and orientation sessions superimposed on mail/telephone outreach was used for fewer participants but had greater enrollment rates (27% and 52%.) Media/advertising was ineffective. The most commonly reported reasons for non-participation were not wanting to be in a research (30%) or a weight loss program (22%); time commitment (20%); and distance/transportation (14%). Conclusions:The use of population registries to identify potential participants coupled with successively more intensive recruitment strategies, executed in a tiered approach moving toward personal engagement to establish trust and credibility, maximized recruitment enrollment rates. Our findings regarding facilitators and barriers to recruitment could be used to inform other practice-based research or to engage patients in group interventions in usual care settings. Clinical trial registration:NCT02320253.

Project description:BackgroundAsian-Americans are one of the most understudied racial/ethnic minority populations. To increase representation of Asian subgroups, researchers have traditionally relied on data collection at community venues and events. However, the COVID-19 pandemic has created serious challenges for in-person data collection. In this case study, we describe multi-modal strategies for online recruitment of U.S. Vietnamese parents, compare response rates and participant characteristics among strategies, and discuss lessons learned.MethodsWe recruited 408 participants from community-based organizations (CBOs) (n = 68), Facebook groups (n = 97), listservs (n = 4), personal network (n = 42), and snowball sampling (n = 197). Using chi-square tests and one-way analyses of variance, we compared participants recruited through different strategies regarding sociodemographic characteristics, acculturation-related characteristics, and mobile health usage.ResultsThe overall response rate was 71.8% (range: 51.5% for Vietnamese CBOs to 86.6% for Facebook groups). Significant differences exist for all sociodemographic and almost all acculturation-related characteristics among recruitment strategies. Notably, CBO-recruited participants were the oldest, had lived in the U.S. for the longest duration, and had the lowest Vietnamese language ability. We found some similarities between Facebook-recruited participants and those referred by Facebook-recruited participants. Mobile health usage was high and did not vary based on recruitment strategies. Challenges included encountering fraudulent responses (e.g., non-Vietnamese). Perceived benefits and trust appeared to facilitate recruitment.ConclusionsFacebook and snowball sampling may be feasible strategies to recruit U.S. Vietnamese. Findings suggest the potential for mobile-based research implementation. Perceived benefits and trust could encourage participation and may be related to cultural ties. Attention should be paid to recruitment with CBOs and handling fraudulent responses.
