Abstract Background Since 1998, China has gradually moved toward voluntary uncompensated blood donation. In some cities, the shortage of platelets has been noticeably severe. Mutual assistance that collects blood from one’s family and social networks is a potential solution. The measure, however, turned out problematic. There are donors who choose to donate platelets over whole blood without compensations, and donate platelets directly to blood banks instead of via the mutual assistance system. This study explores reasons behind their choices qualitatively. Methods This report is based on data conducted from January to February 2018; 25 uncompensated regular platelet donors were interviewed. The blood component donation service team in Guangzhou facilitated the data collection process and referred prospectively eligible blood donors to our research team. The interviews took about 30 min to two hours to complete. The qualitative data were analyzed by using the software ATLAS.ti 8. Results Platelet donation takes a much long time than whole blood donation and requires complicated processes. It may also cause discomfort as the other blood components are returned to the body, causing physical and psychological distress due to worries about contamination. Thus, platelet donation tends to involve higher time and psychological costs than whole blood donation. Yet, it has short collection intervals that allows for more frequent donations, and urgency of a severer shortage than whole blood. Hence, regular platelet donors may feel higher significance in platelet donation than whole blood donation, with the belief that more lives would be saved. Some whole blood donors thus switched to become platelet donors. Mutual assistance blood donation was not chosen by the participants for platelet donation, because such donations may exert moral pressure to both the donors and recipients. Furthermore, “acquaintance” has been loosely defined; the system has sometimes been manipulated to become profit-making monetary transactions. It hence failed. Conclusions The practice of platelet donation reinforces the understanding that blood donation is a gift giving process performed among strangers. A safe and sustainable voluntary blood supply can only be secured in the absence of monetary transactions and moral pressure.

Life Threatening

The abdominal cavity is, in essence, an appendage of the lymphatic system, therefore, it cannot represent a completely foreign container for the blood poured out here. Indeed, the observations of Virchow, Wintrich and others show that whole blood can remain in this cavity for a long time (several days) without undergoing clotting (Pashutin). In view of this fact, it is natural to expect, as is confirmed by experiments, that most of the blood that has entered the abdominal cavity has time to be absorbed before it begins to coagulate. If a part of it, which failed to be absorbed in time, undergoes clotting, then this does not represent any particular disturbances in the overall economy of blood, the blood clot is completely absorbed after preliminary disintegration (fat). In this sense, hemorrhage into the abdominal cavity is not life-threatening, since the blood does not disappear for the body, but soon again, almost entirely, enters the total mass of the blood vessel.

Eligibility Requirements

Abstract Context.—Informed consent in transfusion medicine has been an area lacking of significant research and it is unknown if donors fully comprehend the risks associated with whole blood donation. Objective.—To assess the adequacy of the informed consent process in whole blood donation. Design.—A brief questionnaire was constructed and distributed to whole blood donors visiting various fixed and mobile donor sites of the Central Pennsylvania Blood Bank. Questions consisted of demographic information; donor opinions of information content, length, and comprehension; and a short quiz pertaining to donor risks and eligibility. Results.—Analysis of 849 surveys demonstrated that donors comprehended a mean of 73.5% of the various donor eligibility and risks that were surveyed. Female and younger donors scored statistically higher on comprehension questions compared with male and older counterparts. Donors were most aware of (1) donor eligibility requirements related to acquired immunodeficiency syndrome comprehension, (2) the risk of dizziness postdonation, and (3) having lived in a certain country (93.7%–95.6% comprehension, respectively). Donors were least aware of (1) the risk of a possible referral to a physician for outstanding medical conditions or positive test results, (2) the risk of a positive test result, and (3) West Nile virus testing information (22.4%–49.3% comprehension, respectively). Conclusions.—Whole blood donors believed that they were giving informed consent, but a significant percentage of donors were unaware of several of the risks associated with blood donation, including participation in West Nile virus research testing. Our data suggest that donors do not fully comprehend the risks of whole blood donation and that repetition of information to the donor, and in multiple formats, strengthens the level of comprehension and thus the informed consent process.

The Impact

PurposeAlthough blood banks have recently started to recruit blood donors through social media platforms, including WeChat, to increase recruitment effectiveness, few researchers have studied their effects on blood donation behavior. The aim of this study is to examine the influence of using official WeChat accounts on repeat blood donation behavior.Design/methodology/approachThis paper used the backstage operation data of official WeChat accounts and blood supply chain management system data from the blood bank for the study to analyze the changes in repeat blood donation behavior. First, to analyze the changes in the average frequency of blood donation per year, average volume of single blood donation and blood eligible rate of repeat blood donors before and after following the official WeChat accounts by difference-in-differences model combined with propensity score matching (PSM-DID). Second, we examined the impact of official WeChat accounts on the proportion of repeat blood donors through survival analysis.FindingsThe results show that following WeChat accounts increases the average frequency of blood donation and blood eligible rate of repeat blood donors by 14.36% and 1.19%, respectively, and have no significant effect on the average volume of single blood donation. Further, WeChat accounts have a more significant impact on the average frequency of blood donations per year for workers, farmers, medical staff and groups with education levels of junior high school. In addition, official WeChat accounts can effectively increase the proportion of repeat donors.Originality/valueThe results provide a quantitative basis for the influence of official WeChat accounts on repeat blood donation behaviors. On the one hand, it is of great significance to guide the publicity and recruitment of unpaid blood banks. On the other hand, it provides an evidence for the promotion of official WeChat accounts.

SUMMARYObjectiveTo compare four haemoglobin measurement methods in whole blood donors.BackgroundTo safeguard donors, blood services measure haemoglobin concentration in advance of each donation. NHS Blood and Transplant’s (NHSBT) usual method has been capillary gravimetry (copper sulphate), followed by venous HemoCue® (spectrophotometry) for donors failing gravimetry. However, gravimetry/venous HemoCue® results in 10% of donors being inappropriately bled (i.e., with haemoglobin values below the regulatory threshold).MethodsThe following were compared in 21,840 blood donors (aged ≥18 years) recruited from 10 mobile centres of NHSBT in England, with each method compared with the Sysmex XN-2000 haematology analyser, the reference standard: 1) gravimetry/venous HemoCue®; 2) “post donation” approach, i.e., estimating current haemoglobin concentration from that measured by a haematology analyser at a donor’s most recent prior donation; 3) capillary HemoCue®; and 4) non-invasive spectrometry (MBR Haemospect® or Orsense NMB200®). We assessed each method for sensitivity; specificity; proportion of donors who would have been inappropriately bled, or rejected from donation (“deferred”) incorrectly; and test preference.ResultsCompared with the reference standard, the methods ranged in test sensitivity from 17.0% (MBR Haemospect®) to 79.0% (HemoCue®) in men, and from 19.0% (MBR Haemospect®) to 82.8% (HemoCue®) in women. For specificity, the methods ranged from 87.2% (MBR Haemospect®) to 99.9% (gravimetry/venous HemoCue®) in men, and from 74.1% (Orsense NMB200®) to 99.8% (gravimetry/venous HemoCue®) in women. The proportion of donors who would have been inappropriately bled ranged from 2.2% in men for HemoCue® to 18.9% in women for MBR Haemospect®. The proportion of donors who would have been deferred incorrectly with haemoglobin concentration above the minimum threshold ranged from 0.1% in men for gravimetry/venous HemoCue® to 20.3% in women for OrSense®. Most donors preferred non-invasive spectrometry.ConclusionIn the largest study reporting head-to-head comparisons of four methods to measure haemoglobin prior to blood donation, our results support replacement of venous HemoCue® with the capillary HemoCue® when donors fail gravimetry. These results have had direct translational implications for NHS Blood and Transplant in England.

The Individual

Blood is one of the fundamental tissues of our body. Blood donation allows blood banks to meet hospital needs for blood components. Blood transfusion is an activity that carries a risk, originated by a series of causal actions derived from the individual characteristics of donors and patients. Blood components are biological products and as such, they can never be exempt from the risk of transmitting infectious diseases, such as hepatitis B, HIV, syphilis, among others. Thanks to the investigation of the donor database of the Blood Bank of Hospital Dr. Carlos Luis Valverde Vega and the annual statistics of the blood bank, the statistics referring to donations were obtained, according to the type, grade of acceptance and as well as the prevalence of mandatory screening infectious diseases in the blood bank, between the years 2015 and 2019, with the respective authorization of the corresponding scientific ethics committee. This study reported a prevalence for Anti HB Core of 0.99%, 0.14% for HBsAg, 0.11% for syphilis, 0.05% for hepatitis C, 0.02% for HIV and 0% for the disease de Chagas and HTLV I / II. By using the bases of this work, future analyzes with a similar premise may be developed in different blood banks of the different health centers in our country.

Cruzi Infection

Between October 1988 and April 1989 a cross-sectional survey was carried out in six out of eight blood banks of Goiânia, Central Brazil. Subjects attending for first-time blood donation in the mornings of the study period (n = 1358) were interviewed and screened for T. cruzi infection as a part of a major study among blood donors. Tests to anti-T. cruzi antibodies were performed, simultaneously, by indirect hem agglutination test (IHA) and complement fixation test (CFT). A subject was considered seropositive when any one of the two tests showed a positive result. Information on age, sex, place of birth, migration and socio-economic level was recorded. Results from this survey were compared with seroprevalence rates obtained in previous studies in an attempt to analyse trend of T. cruzi infection in an endemic urban area. The overall seroprevalence of T. cruzi infection among first-time donors was found to be 3.5% (95% confidence interval 2.5%-4.5% ). The seroprevalence rate increased with age up to 45 years and then decreased. Migrants from rural areas had higher seroprevalence rates than subjects from urban counties (1.8%-16.2% vs. 0%-3.6%). A four fold decrease in prevalence rates was observed when these rates were compared with those of fifteen years ago. Two possible hypotheses to explain this difference were suggested: 1. a cohort effect related with the decrease of transmission in rural areas and/or 2. a differential proportion of people of rural origin among blood donors between the two periods. The potential usefulness of blood banks as a source of epidemiological information to monitor trends of T. cruzi infection in an urban adult population was stressed.
