Background In May 2000, a county judge ruled that donating blood could reduce social service time penalties. The blood center began to monitor such blood donation activity immediately after learning about it from the news media. This plan requires verifying that blood donors are themselves in need of social services and giving them a proof that they serve the community. After six months of implementation, there are no major problems with this plan. By November 2000, the plan had been extended to other counties and entered the regional court. With the implementation of the plan, the number of positive blood donors found to serve the community has increased. Methods February 2001, statistical analysis, collection of positive screenings from May 2000 to February 2001
