OBJECTIVES
To identify ways to improve the operation of blood-screening programs and to decrease the inappropriate use of blood by evaluating blood-transfusion practices and blood-banking services in a Kenyan hospital.
DESIGN
Prospective cohort.
SETTING
The study was conducted in a rural district hospital in western Kenya between September 1990 and July 1991.
METHODS
We collected data on all transfusion requests (blood donation, grouping, HIV screening) and blood recipients (age, sex, diagnosis, and for a 3-month period on the pediatric, maternity, and female wards, admission hemoglobin and outcome).
RESULTS
During the 11-month study period, 799 patients received 927 transfusions: 67% were children < 15 years of age, 27% were adult women and 6% were adult men. Transfusions were often delayed due to reliance on patient-recruited donors. Patients who received blood donated on or after the date of request waited longer for transfusion (median, 3 days) than patients who received blood that had been banked and screened before the request (median, 1 day). Patient-recruited donors had a higher HIV-seropositivity rate than volunteer donors (13.4 and 4.6%, respectively; chi 2 test, P < 0.001). Overall, 47% of pediatric transfusions were classified as inappropriate: 23% did not meet the criteria of having hemoglobin < 5.0 g/dl and clinical evidence of respiratory distress, and 27% were transfused 2 or more days after requested. Among adults, 68% received one unit of blood or less.
CONCLUSIONS
Improved laboratory services, reduction of unnecessary transfusions, and increased recruitment of volunteer donors are critical for improving the appropriate and timely use of blood and reducing transfusion-associated HIV transmission.
目的
通过评估肯尼亚一家医院的输血实践和血库服务,确定改善血液筛查项目运作及减少血液不当使用的方法。
设计
前瞻性队列研究。
地点
1990年9月至1991年7月在肯尼亚西部的一家农村地区医院开展该研究。
方法
我们收集了所有输血申请(献血、血型鉴定、HIV筛查)以及受血者的数据(年龄、性别、诊断情况,并且在儿科、产科和妇科病房进行了为期3个月的调查,包括入院时血红蛋白水平及转归情况)。
结果
在为期11个月的研究期间,799例患者接受了927次输血:67%为15岁以下儿童,27%为成年女性,6%为成年男性。由于依赖患者招募的献血者,输血常常延迟。接受申请日期当日或之后所献血液的患者等待输血的时间(中位数为3天)比接受申请前已储存并筛查过的血液的患者更长(中位数为1天)。患者招募的献血者的HIV血清阳性率高于志愿献血者(分别为13.4%和4.6%;卡方检验,P<0.001)。总体而言,47%的儿科输血被归类为不当输血:23%不符合血红蛋白<5.0 g/dl且有呼吸窘迫临床证据的标准,27%在申请后2天或更长时间才输血。在成年人中,68%接受了1单位或更少的血液。
结论
改善实验室服务、减少不必要的输血以及增加志愿献血者的招募对于改善血液的合理及时使用及减少与输血相关的HIV传播至关重要。
