“…It is essential to keep a healthy, satisfied, and reliable donor population and is therefore highly prioritized in blood bank settings all over the world. Adverse effects such as dizziness, fatigue, and vasovagal reactions are proven causes of donor deferral and thus, are still of high concern and interest to health care professionals . Studies on adverse effects and how to avoid them have led to the implementation of standard procedures to limit negative side effects of donation worldwide …”

BACKGROUND Occasionally blood donation has a negative influence on some donors, while others express feelings of increased energy or wellbeing after donation. Some donors even report symptoms such as headache or feelings of unease indicating “it is time to donate blood again.” This study aims to determine symptoms and frequencies of blood donors experiencing positive and negative effects of blood donation, and study possible associations with sex, age, body mass index, smoking status, and hemoglobin level. STUDY DESIGN AND METHODS We developed and validated a questionnaire with eight predefined physical and psychological symptoms related to blood donation using a 5‐point Likert Scale. Participants in The Danish Blood Donor Study were asked to indicate if they experienced the present symptom prior to and/or after the donation. RESULTS A total of 6,073 donors were included. Of the donors, 61% experienced one or more effects of blood donation. Positive effects were experienced by 18% of the donors, 29% experienced negative effects, and 14% experienced both. Most notable positive effects were alleviated headache (14%), feeling lighter (14%), and less tiredness (7%). Most notable negative effects were less energy (25%), more dizziness (22%), and more tiredness (21%). Logistic regression analysis revealed that positive effects were more likely among donors with higher BMI, older donors, and smokers. Negative effects were more likely among younger donors, donors with lower BMI, and among female donors. CONCLUSION Analyses indicate that susceptibility to blood donation effects varies by BMI, sex, smoking status, and age, and therefore should be taken into consideration when informing donors about potential effects of blood donation.

“…Studies show that donors who donated blood for the first time often turn to lapsing donors and donation habits begin at fourth donation levels . It was seen that the most risky group for lapsing donors were young donors, female donors and those living in urban areas . In our analyses, it was seen that the group most at risk for lapsing donors was also young donors.…”

“…In our analyses, it was seen that the group most at risk for lapsing donors was also young donors. The current literature supports that the occurrence of adverse events such as vasovagal reaction and fatigue in first blood donors is important in the loss of donors . Donors, particularly those who give blood for the first time, should be followed carefully for vasovagal reactions, fatigue and stress due to adverse events.…”

“…If we can provide the donor retention who have previously donated blood in the system and if they continue to donate, this is more advantageous than the new donor recruitment. Studies show that donors who donated blood for the first time often turn to lapsing donors and donation habits begin at fourth donation levels . It was seen that the most risky group for lapsing donors were young donors, female donors and those living in urban areas .…”

Objectives The Turkish Red Crescent has been the responsible body and created the national blood banking system in Turkey. In this study, we aimed to share the 9 years’ experience of the Turkish Red Crescent in blood donor management practice for a better understanding of donors’ motivations which might improve the ability of a blood bank to provide a more robust blood supply. Materials and Methods Blood Banking Information Management System of Turkish Red Crescent allows to follow the donor behaviours throughout in the country. In this study, donors who are registered in the Turkish Red Crescent system were evaluated according to the DOMAINE (Donor Management IN Europe) definitions in terms of donor populations and donor behaviours. The improvement of blood donor numbers and the change of behaviours with time is analysed and discussed. Results While 24% of the total blood donors in 2009 were regular donors, the number of regular donors increased over the years to 41% in 2017 with the help of donor acquisition programmes. However, it is observed that 1 106 351 of the donors registered in the Turkish Red Crescent system (13%) are silent donors and 4 269 909 persons (49·7%) are inactive donors (As of 10 March 2018). Conclusion Classification and analysis of blood donors in the system helps to create incentives to increase the number of regular blood donors. Good donor management can be achieved by classifying donors using DOMAINE definitions and developing new strategies with appropriate donor management programmes.

“…With over 1.2 million donations per year in Australia, the absolute number of VVR is notable. As most donors who experience a VVR do not return to donate, and the cost of continually attracting new donors comes at a considerable expense . Operationally, it is useful to understand collection centre to collection centre variation on reported VVRs after adjusting for a “donor‐risk” profile.…”

A novel case‐control subsampling approach for rapid model exploration of large clustered binary data

In many settings, an analysis goal is the identification of a factor, or set of factors associated with an event or outcome. Often, these associations are then used for inference and prediction. Unfortunately, in the big data era, the model building and exploration phases of analysis can be time-consuming, especially if constrained by computing power (ie, a typical corporate workstation). To speed up this model development, we propose a novel subsampling scheme to enable rapid model exploration of clustered binary data using flexible yet complex model set-ups (GLMMs with additive smoothing splines). By reframing the binary response prospective cohort study into a case-control-type design, and using our knowledge of sampling fractions, we show one can approximate the model estimates as would be calculated from a full cohort analysis. This idea is extended to derive cluster-specific sampling fractions and thereby incorporate cluster variation into an analysis. Importantly, we demonstrate that previously computationally prohibitive analyses can be conducted in a timely manner on a typical workstation. The approach is applied to analysing risk factors associated with adverse reactions relating to blood donation.
