Cost Analysis of Participant Recruitment at a Community Site to Promote Colon Cancer Screening in Underserved Populations

A cost analysis was done on the participant recruitment for an ongoing research project to promote colon cancer screening in Phoenix, Arizona. The aim of the 5-year project is to navigate people, who do not regularly see primary care physicians, from the community to a nearby clinic to be screened, using an intervention strategy called tailored navigation. Through tailored navigation, participants' barriers to being screened are addressed by Community Health Navigators, who call the participant over the span of 8 weeks following an initial class at a community site and give them information on how to overcome his or her specific barrier. The objective of this cost analysis is to explore the costs of recruiting a participant from the community to the initial class to a potential program manager. The process of recruitment involved recruitment of a community site, project introduction, the sign-up of interested participants, eligibility, baseline, and consent tests, and the class itself. A Community Site Liaison recruits sites and schedules class times. The Community Health Navigator conducts eligibility, baseline, and consent surveys and teaches the class, a sixty minute presentation on colon cancer screening. The cost of recruitment per community site was $541.23, and the cost per participant attending class was estimated to be $1,594.41 per participant with variation between $1,379.97 and $1,770.71 in optimistic and conservative scenarios, respectively.
