| Blood,as a non-renewable resource,plays an important role in medical healthcare.Blood transfusion medicine is an important part of modern medicine.A large number of researches have promoted the development of blood transfusion medicine and improved the safety of blood transfusion.Henan Province has a large population in China,Zhengzhou as the capital city,including the jurisdiction of 6 municipal districts,5 county-level cities and 1 county.Zhengzhou undertakes more medical tasks than other cities in Henan,so it leads to clinical blood supply tension,especially seasonal ischemia.Moreover,due to the uneven development of medical resources,large and super large medical institutions are concentrated in Zhengzhou,which resulted in the lowest average amount of blood available in each hospital bed.Therefore,it is of great significance to understand the present situation of blood donation in Zhengzhou for the rational distribution of medical resources,the recruitment of blood donors and the safety of blood transfusion in Zhengzhou even in Henan Province in the future.ObjectiveTo understand the population characteristics,blood type composition and blood qualification of blood donors in Zhengzhou from 2017 to 2019,so as to provide basis for clinical blood safety and blood donor recruitment.Methods(1)Subjects:the subjects were blood donors who donated blood in Zhengzhou,from 00:00 on January 1,2017 to 23:59 on December 31,2019.All the subjects met the requirements of Blood Donor Health Examination Requirements(GB18467-2011.)(2)Data collection:information of donors was collected through the SHINOW9.0 system from 00:00 January 1,2017 to 23:59 December 31,2019,including population characteristics,regional composition,time distribution of blood donation,composition of blood samples and blood qualification.(3)Data entry and analysis:these data were summarized and analyzed through EXCEL 2019 software by double input.Results(1)From 2017 to 2019,the number of voluntary blood donors in Zhengzhou increased year by year,from 213997 in 2017 to 251788 in 2019,and the blood donation rate increased year by year,which was at 21.7‰,23.4‰and 24.3‰over these three years,respectively.(2)Total donation of whole blood and platelets were 2.1×10~8 ml and 2.0×10~5 u over the three years.The total proportion in the form of whole blood and platelet donation was 84.19%and 15.81%,respectively.Blood donation both in whole blood form and platelet increased year by year.From 2017 to 2019,total blood donation increased from 6.5×10~7 ml to 7.5×10~7 ml and total platelet donation increased from5.8×10~4 u to 7.3×10~7 u.In addition,the proportion of 400 ml in whole blood donated was higher than that of other groups,as well as the proportion of 2 u in platelets.(3)The number of first-time donors and repeat donors increased from 111567 to116539 for first donors and from 102430 to 135249 for repeat donors,respectively.The number of repeat donors increased 18.92%in 2018 compared with 2017 and 11.04%in 2019 compared with 2018,which was higher than that of ring growth rate in the first donors in the same period(3.11%and 1.30%),while the proportion of first donors decreased and the proportion of repeat donors increased.(4)The number of blood type including ABO and Rh D increased year by year;After detecting the blood samples collected each year,4397(2.05%),4358(1.84%)and4597(1.83%)of unqualified blood samples were totally detected.The total unqualified rate gradually decreased.The unqualified rate of HBV,HCV and TP decreased,while the unqualified rate of ALT,HIV and NAT increased in contrast.(5)Of all voluntary blood donors in Zhengzhou from 2017 to 2019,the ratio of male to female was 1.92 to 1.What’s more,blood donation decreased with age increased,of which the proportion of group from 18 to 25 years ranked first(35.85%).Among all occupations,students account for the most(28.17%).Except for unknown occupations,the proportion of farmers ranked second(9.11%).Moreover,university students’donors among all education level accounted the most(24.49%).In all nationalities,Han donors were the significantly most(97.75%).(6)The number of donors showed a seasonal distribution.Compared with spring,the growth in summer is 16.69%ring lower than that in spring,21.15%ring increased in autumn than in summer,and 25.67%ring decreased in winter than in autumn.It appeared peak in spring and autumn and trough in summer and winter.Meanwhile,it reached the highest level in November(11.82%)than in other months.(7)Among all the counties in Zhengzhou,Jinshui District held the largest number of donors(34.18%),which was higher than the other 11 counties.Conclusions(1)From 2017 to 2019,it showed an increasing trend among the total number of voluntary blood donors,the total amount of whole blood and platelet year by year.What’s more,the rate of repeat donors increased,too.(2)Totally,the unqualified rate of blood samples has been decreased.The unqualified rate of ALT,HIV and NAT in blood samples increased from 2017 to 2019,while the unqualified detection rate of HBV,HCV and TP decreased.(3)Among the voluntary blood donors in Zhengzhou from 2017 to 2019,the Han nationality is the main group,with more men than women.And the largest proportion was college students.Jinshui District held the largest number of donors.Meanwhile,the number of donors showed a seasonal distribution. |
