ABSTRACT
Objective To form the basis of establishing a strategy for safe blood donor recruitment and to identify and subdivide the structures of donors.Methods Demographic data of blood donors, and blood testing results of HBsAg, anti-HCV, anti-HIV, and syphilis, from Nov. 2004 to Jun. 2005, were collected and analyzed.Results Among the 45270 voluntary blood donors, the total positive test rate were 3.11%, which was related to age, level of education and occupation of blood donors. About 76.7% of donors were young people, aged from 18 to 30. As the age increased, female donors were less than male ones. Among all the donors, 81.6% received higher education, which had lower positive test rate than those with lower level of education. Among the 45270 donors, farmers had the highest positive test rate; workers and service people came the second; students and medical staff had the lowest. As to donors with incomplete record, the positive test rate was higher than those with complete record.Conclusion During blood donor recruitment, quality control is important. People younger than 30, with student or higher education background, are relatively safe to recruit.
ABSTRACT
Objective To investigate the blood collection and supply in Chengdu,from 2000 to 2006,and also to analyze its development tendency.Methods The volume of blood collection,blood component preparation,the positive rate of blood screening,the volume of clinical consumption,as well as the population statistics and bed numbers in medical institutions and hospitals,from 2000 to 2006,were reviewed.Correlation and coefficient of regression were used for the statistical analysis.Results The annual average rate of growth(AARG) of blood collection and supply is 17.74%.The rate of RBC separation increased from 27.4%% to 84.55%,and the AARG of platelet apheresis product was 38.00%.Blood components had become much more popular than whole blood in clinical application.There was a good linearity correlation between the blood provision and the population statistics(?=0.997,P
ABSTRACT
Objective To find out factors influencing voluntary blood donation activities and establish the most appropriate method for recruiting blood donors. Methods Questionnaire investigation of donors and data analysis by SPSS+ software. Results In Chengdu city, 2385 residents' knowledge on nonrenumerated blood donation was as follows: among the 2385 residents, the percentage of people who knew the government policies of blood donation was high (87.5%), but the percentage having common knowledge of blood donation was only 29.4%, of risk behavior was 32.5%. Among the 1349 participants who had donated blood, the percentages having common knowledge of blood donation and risk behavior were 33.4% and 38.1% respectively, compared to the 1036 participants who never donated (24.2% and 25.1%, respectively)(P
