Blood Service in a Region of China's Qinghai-Tibetan Plateau

Objectives: The purpose of this paper is to describe blood services in the Aba Tibetan and Qiang Regions, (hereinafter referred to as Aba Prefecture), a region of China's Qinghai-Tibetan Plateau, the third largest area of Tibet and the main inhabited area of the Qiang people. Design: We present a comprehensive investigation into blood donations, donors, screening and supply in the 13 counties of Aba Prefecture based on data from 2013 to 2018. Geography and population were also used to analyze the differences in blood services among different regions. Participants: The number of blood donors totaled 19,047. Results: Over the past 6 years, blood donations have increased by 29 and clinical blood usage by 45%. The blood donation rate was 3.4 & PTSTHOUSND; and per capita blood use was 1.04 mL, both of which were significantly lower than the national average, and blood donation decreased with altitude. It should be noted that the donation rate of the Tibetan and Qiang peoples is much lower than that of the Han population. Moreover, the rejection rate of blood in laboratory testing was found to be higher than the national average, especially in counties located at higher altitudes. Conclusions: Blood donations and usage increased every year in Aba Prefecture, but blood shortage is still an important issue. In addition, the prevalence of transfusion-transmitted diseases is relatively high, which may be linked to lower-education and unfavorable geographical and medical conditions.

Automated summary

This paper describes the blood services in the Aba Tibetan and Qiang Regions in China's Qinghai-Tibetan Plateau. A comprehensive investigation into blood donations, donors, screening, and supply in the region was conducted based on data from 2013 to 2018. The results showed an increase in blood donations and usage, but a shortage of blood is still an important issue. The prevalence of transfusion-transmitted diseases is relatively high, possibly due to lower education levels and unfavorable geographical and medical conditions.
