Lessons learned for recruitment and retention of low-income African Americans

Recruitment and retention of low-income African Americans in clinical trials is challenging. This paper reports recruitment and retention strategies that yielded high rates for both in a clinical trial pilot to improve hypertension self-management among low-income African Americans. The study successfully recruited 96.7% (59 of 61 participants) within a seven month period. Retention rates for the 1, 3, and 6-month post-baseline assessment visits were 91.5%, 88.1%, and 83.1%, respectively. Recruitment and retention strategies include two grounded in previous literature: a culturally sensitive and diverse research team and use of incentives. Four additional strategies were developed for this study to meet the needs of the study site and participants, which included: study site collaboration; ongoing communications; responding to the clinical environment; and addressing participants' health literacy levels. A discussion of key recruitment and retention strategies and suggestions for future studies focused on low-income African American participants ensues.
