Popis: BACKGROUND: Whole-blood donation times in a donor population when there are no impediments to blood donation at any point can be used to determine the shortest median whole-blood donation time. This statistic is relevant to blood donors and collection staff. STUDY DESIGN AND METHODS: Small, overstaffed blood drives in August 2004 were evaluated via operation records and supervisor interviews to determine if there were any impediments to whole-blood donation at any point in the process. Four-hundred ninety-two whole-blood donations from 33 blood drives were not impeded and were evaluated for whole-blood donation times. Registration records (entry time) and blood donor records (phlebotomy start and end time) provided three objective time points for the process, the median postphlebotomy interval at the phlebotomy station was estimated, and 10 minutes was assigned for the refreshment period. RESULTS: The median donation time for the whole-blood donation process was 50 minutes. The 25 to 75 percent range was 46 to 56 minutes, and the 10 to 90 percent range was 42 to 64 minutes. First-time blood donors had blood donation times that were 5 to 6 minutes longer than in repeat blood donors (55.5 min vs. 50 min), and women had slightly longer donation times than men (51 min vs. 49 min). Five percent of the donors had donation times that exceeded 69 minutes. CONCLUSION: The median whole-blood donation time and range under the best circumstances was defined based on the process in place in our blood center in August 2004.
