To collect population based information on transfusion of red blood cells.
Prospective observational study over 28 days.
Hospital blood banks in the north of England (population 2.9 million).
Indications for transfusion, number of units given, and the age and sex of transfusion recipients.
All patients who received a red cell transfusion during the study period. Data completed by hospital blood bank staff.
The destination of 9848 units was recorded (97% of expected blood use). In total 9774 units were transfused: 5047 (51.6%) units were given to medical patients, 3982 (40.7%) to surgical patients, and 612 (6.3%) to obstetric and gynaecology patients. Nearly half (49.3%) of all blood is given to female recipients, and the mean age of recipients of individual units was 62.7 years. The most common surgical indications for transfusion were total hip replacement (4.6% of all blood transfused) and coronary artery bypass grafting (4.1%). Haematological disorders accounted for 15.5% of use. Overall use was 4274 units per 100 000 population per year.
In the north east of England more than half of red cell units are transfused for medical indications. Demand for red cell transfusion increases with age. With anticipated changes in the age structure of the population the demand for blood will increase by 4.9% by 2008.
收集基于人群的红细胞输血信息。
为期28天的前瞻性观察性研究。
英格兰北部的医院血库（人口290万）。
输血指征、输注单位数量以及输血受者的年龄和性别。
研究期间所有接受红细胞输血的患者。数据由医院血库工作人员填写。
记录了9848个单位的去向（占预期用血的97%）。总共输注了9774个单位：5047个单位（51.6%）输给内科患者，3982个单位（40.7%）输给外科患者，612个单位（6.3%）输给妇产科患者。几乎一半（49.3%）的血液输给了女性受者，单个单位受者的平均年龄为62.7岁。最常见的输血外科指征是全髋关节置换术（占所有输血的4.6%）和冠状动脉搭桥术（4.1%）。血液学疾病占用血的15.5%。总体用量为每年每10万人口4274个单位。
在英格兰东北部，超过一半的红细胞单位因内科指征而输注。红细胞输血需求随年龄增长而增加。随着预期的人口年龄结构变化，到2008年血液需求将增加4.9%。
