To determine what proportion of blood transfusions given in Mwanza Region, Tanzania could be avoided.
A total of 1029 patients who received a blood transfusion in one of eight hospitals were analysed. Two sets of criteria for avoidable blood transfusions were determined, on the basis of a literature review.
The following percentages of blood transfusions in five groups of patients were found to be avoidable: operated patients, 8-24%; pregnant women, 8-10%; children aged under 5 years, 31-52%; children aged 5-14 years, 23-25%; and adults, 16-25%. Overall, 23-39% of blood transfusions were avoidable. At least 75% of all avoidable blood transfusions were to children aged under 5 years.
The largest reduction of blood transfusions can be achieved in children aged under 5 years, especially in infants aged less than 1 year. Following this study, blood transfusion prescribers drew up provisional guidelines on blood transfusions, which have been introduced in all hospitals in Mwanza Region. An evaluation study has been carried out and is being analysed.
确定坦桑尼亚姆万扎地区可避免的输血比例。
对在八家医院之一接受输血的1029名患者进行了分析。在文献综述的基础上确定了两组可避免输血的标准。
发现五组患者中以下百分比的输血是可避免的：手术患者，8 - 24%；孕妇，8 - 10%；5岁以下儿童，31 - 52%；5 - 14岁儿童，23 - 25%；成人，16 - 25%。总体而言，23 - 39%的输血是可避免的。所有可避免输血中至少75%是针对5岁以下儿童。
5岁以下儿童，尤其是1岁以下婴儿，输血减少幅度最大。在这项研究之后，输血开方者制定了输血暂行指南，已在姆万扎地区所有医院推行。一项评估研究已经开展并正在进行分析。
