患者亲属互助献血与街头自愿无偿献血相关因素对比分析 总被引:1,自引:0,他引:1
目的:探讨患者亲属互助献血与街头自愿无偿献血的差异。方法:对2类不同献血类型的相关因素对比分析。结果:①患者亲属互助献血人员构成与年龄及受教育程度无关,而自愿无偿献血者以25岁年轻人为主体,献血积极性与文化程度高低成正比,且比例明显高于互助献血者。②互助献血献血反应发生率及卫生部规定的4项血液传播性疾病检测阳性检测率明显高于自愿无偿献血者。结论:患者亲属互助献血多从亲情和友情角度出发,多属有目的的被动献血,只能做为无偿献血血源紧缺及偏型的暂时补充,目前无偿献血的宣传工作,应针对不同人群加大宣传力度和广度,使这部分人自愿加入到无偿献血的队伍中来。 相似文献

Background Whole blood (WB) donation encompasses several periods during which some donors faint. Identification of factors associated with fainting during each period should guide intervention strategies. Reducing faint reactions may reduce donor injuries and disability. Methods Blood donation was divided into three periods: Period 1 – registration; Period 2 – phlebotomy; and Period 3 – post‐phlebotomy. Period 3 consists of two sub‐periods (3A – on‐site and 3B – off‐site). For each Period, stratified rates of fainting in relation to various donor and donation characteristics were calculated and multivariable logistic regression analyses to identify factors associated with fainting were conducted. Donor injuries in each period were also analysed. Results Of the 956 766 donors registered in 2007, 554 534 (58%) donated WB. There were 43 fainting episodes and two injuries in Period 1 and 1520 faints and 73 injuries in Periods 2 and 3. Regression analyses showed that youth and donor first‐time status are associated with fainting in all periods; but most significantly in Period 1. Small estimated blood volume is notably not a factor in Period 1 but is significant in Periods 2 and 3. The highest injury rate is seen in Period 3A (0·07 and 0·09/1000 donations) for male and female donors, respectively. Conclusions Variability in factors associated with fainting across defined periods of the donation process suggest differing underlying mechanisms and the possibility that interventions for the reactions most associated with injury during each time period can be designed. The highest rate of injury per donation occurred in ambulating donors. 相似文献

BACKGROUND: Population-based data on the rate and outcome of complications related to blood donation are sparse. STUDY DESIGN AND METHODS: Data from a survey conducted in 2003 in Aarhus County, Denmark, were used to assess the overall rate of donor complications. Additional nationwide data on moderate and severe donor complications were obtained from the Danish Register of Complications Related to Blood Donation, with records of all moderate and severe donor complications in Denmark occurring during the period 1997-2003. RESULTS: In the regional survey, we identified 340 complications of any type among 41 274 donations, corresponding to a rate of 824/100,000 donations [95% confidence interval (CI): 741-916]. All complications were either needle injuries or vasovagal reactions. In the nationwide register, a total of 752 moderate and severe complications were recorded among 2,575,264 donations, corresponding to a rate of 29/100,000 donations (95% CI: 27-31). The rates of complications leading to long-term morbidity or disablement (> 5% loss of working capacity) were 5/100,000 donations (95% CI: 4.2-5.9) and 2.3/100,000 donations (95% CI: 1.8-2.9), respectively. CONCLUSION: The risk of complications related to blood donation is low. However, attention towards donor complications is warranted, given the non-negligible rate of complications resulting in long-term morbidity and disablement. 相似文献

Blood services are reliant upon healthy blood donors to provide a safe and adequate supply of blood products. Inappropriate variables contained within blood donor exclusion criteria can defer potentially appropriate donors. The aim of this systematic review was to examine the effect of low pre-donation blood pressure, as compared with normal blood pressure, on adverse events in allogeneic whole blood donors. A systematic review was performed using highly sensitive search strategies within five databases (Cochrane Central Register of Controlled Trials, CINAHL, Embase, MEDLINE, and Web of Science) from inception date until April 12, 2013. Out of 8305 records, 10 observational studies were identified that addressed the question. Five of these studies (with a combined total of 1,482,020 donations and 2903 donors) included either a statistical analysis or an appropriate study design that controlled for possible confounding factors. Based on the currently available evidence, hypotension has not been shown to be an independent predictive factor for donor complications. However, the overall quality of evidence was rather limited and rated ‘low,’ using the GRADE approach. In conclusion there is currently no evidence that hypotensive blood donors have a greater risk for donor adverse events compared with their normotensive counterparts. 相似文献

Background
Voluntary donors normally tolerate blood donation very well, but, occasionally, adverse reactions of variable severity may occur during or at the end of the collection. Aim of this study was to estimate and possibly avoid the cause of unwanted reactions.Materials and methods
The study was conducted over a period of 6 months, from 24th October, 2005 to 24th April 2006. The donor population analysed consisted of 4,906 donors (3,716 male and 1,190 female). In total, 3,983 (81%) voluntaries have donated whole blood, 851 (17%) plasma from apheresis, 64 (1.3%) experienced multicomponent donation, and 8 (0.1%) were donors of plasma-platelet apheresis.Results
Only 63 donors (1.2% of all the volunteers) suffered some kind of adverse reaction: 59 (1.08% of the subjects) had mild reactions (agitation, sweating, pallor, cold feeling, sense of weakness, nausea), and only 4 (3 males and 1 female, 0.2%) had more severe disorders, including vomiting, loss of consciousness, and convulsive syncope.Conclusions
Although the number of donors who developed disturbances during or at the end of blood donations was very low, it is nevertheless desirable to reduce risks to a minimum. A set of advices is provided for preventing problems. 相似文献16.
Background
The aim of this study was to determine any relationships between return rates of first-time donors, number of donations in the first year and the donors’ demographic characteristics.Materials and methods.
Data from 1,500 volunteer, first-time donors who donated blood at Shiraz Blood Transfusion Centre (Iran) were obtained from the donor database. The donors’ demographic characteristics (sex, age, educational status) and donation histories were obtained for a 3-year period and the number of donations and interval between the first donation and the following donation within a 1-year period were recorded. We searched for correlations between return rate and demographic characteristics and the number of donations in the first, second and third years. The data were analysed with the chi-squared test, multiple logistic regression and Spearman’s correlation tests. P values less than 0.05 were considered statistically significant.Results
More than half of the first-time donors returned to donate again (n=776, 51.7%) during the 3 years after the first donation. The mean number of donations in the whole 3-year period was 0.69±0.49, while it was 1.33±0.62 (median 1) in the first year, 0.4±0.7 (median 0) in the second, and 0.3±0.65 (median 0) in the third year. The return rate was directly correlated with the number of donations in the first year (r=0.74, P<0.001). The return rate increased as the interval between the first and second donations decreased (P<0.05, OR=1.03). The return rate was higher for male donors and single donors (P<0.05), but was not related to age or educational level (P>0.05).Discussion.
In this study 51.7% of first-time donors returned to donate again, a high figure indicating the success of our recruitment strategy. Understanding the importance of the number of donations in the first year for donors’ return rate and planning recruitment programs and more effective measures to encourage donors in the first year may help to increase return rates. 相似文献17.

The blood donation experience: self-reported motives and obstacles for donating blood 总被引:1,自引:0,他引:1
Background and Objectives The aim of the study was to investigate motives for donating blood as well as difficulties and obstacles associated with blood donation as perceived by the donors themselves. Materials and Methods Six hundred consecutive blood donors (i.e. all blood donors with a history of at least one previous whole blood donation attending, during nine working days, the Blood Centre of Umeå University Hospital) received a self‐administered questionnaire that contained questions aimed at elucidating motives for donating blood (general motives for donating blood, specific motives for the first donation and motives for continuing to be an active blood donor). Questions concerning difficulties and obstacles that had to be overcome in order to continue being a blood donor were also included in the questionnaire. Results Altogether 531 whole blood donors filled in the questionnaire (88·5%; 322 men and 209 women). No statistically significant differences were found between male and female blood donors concerning general reasons and motives related to donating blood. The most frequently reported reasons for giving blood the first time were ‘influence from a friend’ (47·2% of donors) and ‘request via media’ (23·5% of donors). Among general reasons/motives with highest ranking of importance, the most commonly reported motive for donating blood were ‘general altruism’ (40·3%), ‘social responsibility/obligation’ (19·7%) and ‘influence from friends’ (17·9%). General altruism’ and ‘social responsibility/obligation’ were also the most frequent reasons for continuing to donate blood (68·4 and 16·0%, respectively). The most commonly reported obstacle to becoming a regular blood donor was ‘laziness’ (19·1%) followed by ‘fear of needles’ (10·5%). Conclusions Altruism was the most common general motive for donating blood and also for continuing to be an active blood donor. Yet, for the first blood donation, direct ‘influence from friends/relatives’, ‘media appeal’ and other types of recruitment were more commonly reported as reasons or motives for donating blood than altruism. The findings support the notion that different strategies should be used/adopted to get people to donate blood the first time (e.g. recruitment through other blood donors using, for example, the ‘bring a friend along’ method) and to retain these subjects as active blood donors (e.g. by information and by strengthening their sense of being a blood donor or their self‐efficacy etc.). 相似文献

Background
Blood supplies in Greece are insufficient to meet the high transfusion needs arising from car accidents and treatment of thalassaemia. This study was designed to determine Greeks’ opinions about blood donation, in order to identify the reasons for the lack of motivation to donate and allow experts to establish better recruitment campaigns for the enrichment of the donor pool, based on our findings.Materials and methods
The opinions of randomly selected Greek citizens (n=800) about volunteer blood donation were assessed by means of a standardised, anonymous questionnaire. The results were analysed using the χ2 test and Spearman’s correlation coefficient.Results
With regards to attitudes towards intention to donate, only 7.1% were indifferent, while 88.0% of the individuals believed that donating blood was an “offer”. Reasons for not donating mainly involved safety (36.0%) and fear (24.0%), whereas need (77.9%) was the most fundamental positive motivation. Of the people enrolled in the present study, 10.0% were active donors, 31.3% occasional donors, 15.0% rare donors and 36.6% non-donors.Discussion
The considerable percentages of occasional and rare donors in comparison with the low proportion of active donors in the Greek donor pool indicates that “need” is a more important motivation for blood donation than altruism in Greece. These results could be useful for establishing advertising campaigns on blood donation and for a more direct approach to the population, aiming for a change in mentality in favour of active blood donation. 相似文献20.
