科学领域:
- 公共卫生 公共卫生
- 传染性疾病 传染性疾病
- 卫生经济学 卫生经济学
背景情况:
- 输血是一种关键的医疗干预,但存在传染病传播的风险,特别是在低收入和中等收入国家 (LMICs).
- 量化输血传播感染 (TTIs) 的负担对于制定有效的血液安全政策至关重要.
- 关于LMIC中TTI流行率和疾病负担的现有数据往往有限,阻碍了有针对性的干预措施.

- 该模型应用于乌干达的数据,使用2019年的输血统计数据.
- 根据残疾调整的寿命年 (DALYs) 被用作疾病负担的主要指标,包括生命损失年 (YLLs) 和残疾寿命年 (YLDs).
主要成果:
- 在乌干达,2019年,估计有298,266个血液单位被输血.
- 这导致估计的TTI发病率为6858例新感染 (2.3%的输血单位) 和19141例TTI的流行率 (6.4%的输血单位).
- 总疾病负担计算为2,903个DALY,包括2,590个YLL和313个YLD.
结论:
- 开发的模型可以计算TTI发病率,流行率和疾病负担在地方和国家层面.

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
