Recruitment of black subjects for a natural history study of intracerebral hemorrhage.

Historically, recruitment of minority subjects for clinical research has been challenging. We developed culturally-tailored recruitment materials for a longitudinal, natural history study of intracerebral hemorrhage (ICH) and trained recruiting coordinators in cultural competence. Of 285 subjects meeting inclusion criteria, 158 (55% of those eligible) agreed to participate (60% of eligible Blacks vs. 45% of eligible non-Blacks, p..02). Of those enrolled, 138 (87%) agreed to participate in the genetic sub-study (86% of Blacks vs. 90% of non-Blacks enrolled, p..78). Of those subjects who refused enrollment, lack of interest in research (42%) was the most common reason given for the study as a whole. A higher rate of enrollment was achieved in Blacks vs. non-Blacks in this ICH clinical research study employing culturally tailored recruitment approaches and training of recruitment coordinators to overcome traditional recruitment barriers to research participation in minority patients.
