Active recruitment increased enrollment in a hereditary cancer registry

The Mid-Atlantic Cancer Genetics Network (MACGN) targets individuals from cancer risk assessment clinics for recruitment into a national hereditary cancer registry. We sought to determine whether different recruitment methods used in a high-risk breast and ovarian cancer clinic yielded differences into enrollment into MACGN.

Two methods of recruitment were compared over an 8-month period. A passive recruitment technique, used during the first 4 months of recruitment, involved distribution of a brochure. An active recruitment method, used during the second 4-month period, required a MACGN recruiter to approach patients and initiate a brief discussion of the registry.

During the first 4-month period, 158 eight patients were seen in the clinic and 142 were seen in the second 4-month period. During passive recruitment, 20% of available patients were approached, compared with 63% during active recruitment. Active recruitment also resulted in fourfold increase over passive recruitment in enrollment (from 15.6% to 67.4%).

Allocating research staff specifically for recruitment and personal contact with potential participants is effective in achieving increased enrollment into a national hereditary cancer research registry.
