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.

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.

Background: Hemovigilance like quality systems and audits have become an integral part of Blood Transfusion Services in the developed countries and has contributed greatly to its development. Hemovigilance begins with donors and must enable the collection of information on reactions occurring during the donation of blood, selections of donors and to prevent such incidents. The aim of study was to help identify the trends of adverse events , occurring in blood donors at a tertiary-care hospital, to recommend best practices to improve donor care and safety Materials and Methods: This record-based study was conducted on all adverse events related to allogenic whole blood donations performed over 24 months. All whole blood donations were analyzed. All adverse events occurring during or at the end of the donation were noted using a standardized format and analyzed determining significance at p<0.05. Results: Overall rate was 0.3% with vasovagal reactions constituting 82%, and 18% mild syncopal reactions (p<0.001). Immediate vasovagal reaction with injury was very rare (0.007%). Vasovagal reactions showed a significant association with young age, female gender, first time donation status. Mean age of persons recording adverse effects was 30.23 ± 7.49 years as compared to those without adverse effects, 31.14 ± 8.56 years. Conclusion: Donor safety is an essential perquisite to increase voluntary blood donation. AE analysis helps in identifying the blood donors at risk of AE, applying appropriate motivational strategies, predonation counseling, care during and after donation, developing guidelines and hemovigilance programme in countries with limited resources.

Intention To Return

With the increasing demand from aging population and seasonal blood shortage, recruiting and retaining blood donors has become an urgent issue for the blood collection centers in China. This study aims to understand intention to donate again from a social cognitive perspective among whole blood donors in China through investigating the association between the blood donation fear, perceived rewards, self-efficacy, and intention to return. A cross-sectional survey was conducted in six cities, which are geographically and socioeconomically distinct areas in Jiangsu, China. Respondents completed a self-administrated questionnaire interviewed by two well-trained medical students. A total of 191 blood donors were included in the current study. Descriptive analysis, correlation analysis, and a generalized linear regression model were used to explore the association between demographic characteristics, psychological factors, and intention to donate again. After controlling other covariates, donors with higher fear scores reported lower intention to return (p = 0.008). Association between self-efficacy and intention to return was statistically significant (p &lt; 0.001), whereas the association between intrinsic rewards (p = 0.387), extrinsic rewards (p = 0.939), and intention to return were statistically insignificant. This study found that either intrinsic rewards or extrinsic rewards are not significantly associated with intention to donate again among whole blood donors in China, and fear is negatively associated with intention to donate again. Therefore, purposive strategies could be enacted beyond appeals to rewards and focus on the management of donors’ fear.
