The Barnes Hospital Apheresis Blood Collection and Blood Transfusion Unit is part of Barns Hospital Blood Bank. Because of its size and complexity, we report our experience which may be useful to administrators and physicians involved in the planning or management of similar services. From 1985 through 1988 we collected platelets from 1,976 different donors, the majority of which (87%) were community donors. Sixty-nine percent of 1,976 donors donated in 1988 an average of 4.9 times. Of 6,568 apheresis products collected. 1.1% were discarded because of positive screening tests and 0.7% were discarded because of outdating or presence of fibrin clot. In 1988 a total of nine cell separators were used. All donor apheresis were done with seven blood separators, and on average a separator produced an apheresis product every 4.5 worked hours. All therapeutic apheresis (338) were done on two separators. Most of them (88%) were performed during work hours. In 1988 donor and therapeutic apheresis were done by 17 1/2 full-time employees (FTEs) during work hours. Considering the Workload Unit Value per procedure given by the College of American Pathologists (CAP) and that each FTE worked 1,864 hours per year, the worked hour productivity for donor and therapeutic apheresis was 78.2%. Blood collections, therapeutic bleeds, and outpatient transfusions (1,127, 114 and 1,745 respectively) were accomplished by two FTEs, for a worked hour productivity of 35.5%. Because 95.1% of total worked units was produced by efficient donor and therapeutic apheresis activities, overall efficiency remained high at 73.8%.
巴恩斯医院单采血液采集与输血科是巴恩斯医院血库的一部分。鉴于其规模和复杂性，我们报告我们的经验，这可能对参与类似服务规划或管理的管理人员和医生有用。1985年至1988年期间，我们从1976名不同的献血者中采集了血小板，其中大多数（87%）是社区献血者。1976名献血者中有69%在1988年献血，平均献血4.9次。在采集的6568份单采产品中，1.1%因筛查试验呈阳性而被丢弃，0.7%因过期或存在纤维蛋白凝块而被丢弃。1988年共使用了9台细胞分离机。所有献血者单采均使用7台血液分离机，平均每台分离机每工作4.5小时生产一份单采产品。所有治疗性单采（338例）均在两台分离机上进行。其中大多数（88%）在工作时间内进行。1988年，献血者和治疗性单采在工作时间内由17.5名全职员工完成。考虑到美国病理学家学会（CAP）给出的每个程序的工作量单位值，且每个全职员工每年工作1864小时，献血者和治疗性单采的工作小时生产率为78.2%。采血、治疗性放血和门诊输血（分别为1127例、114例和1745例）由两名全职员工完成，工作小时生产率为35.5%。由于总工作量单位的95.1%是由高效的献血者和治疗性单采活动产生的，整体效率保持在较高水平，为73.8%。
