“…The study also did not consider specific changes in the aging of the population, which can vary by geography. 41,42 While it is true that older people donate more often and therefore make the largest contributions to the apheresis platelet inventory, our data highlight that over the last decade there has been continuous and strong growth in the youngest age groups, although it is unknown if that growth is sufficient to offset loss of older donors due to aging out and whether it will meet the increasing platelet demand. Since sustainability of the platelet supply is a consequence of both donor acquisition and retention, the long-term stability requires robust engagement of the youngest donors through middle-age sufficient to ensure these donors return when they reach retirement age (or sooner).…”

“…The study data did not include donor center location and other demographic details, nor did it consider policy changes that impact donor eligibility such as organizational shift away from whole blood derived platelets or TRALI‐mitigation strategies which occurred over 2013–2016 resulting in loss of many female FTD and return donors. The study also did not consider specific changes in the aging of the population, which can vary by geography 41,42 …”

Background Platelet demand continues to rise and US hospitals frequently face shortages. The peak median age of apheresis platelet donors (APD) is believed to have increased over the last decade, raising concerns that the APD base is not being adequately replenished with young donors. Study Design/Methods American Red Cross (ARC) apheresis platelet collections were evaluated from calendar years 2010 through 2019. APD, products per procedure/split rate (PPP) and donation frequencies were stratified into age groups. Results/Findings The number of unique APD from calendar year 2010 through 2019 in the ARC donor pool increased from 87,573 to 115,372 donors, representing a 31.7% overall growth. Donors in the 16–40 year‐old (y) age group increased by 78.8% overall, with the largest absolute increases seen in the 26–30 y (4852 donors, 99.9% growth), followed by the 31–35 y (3991, 94.1%) group. Donors aged 56+ increased by 50.4% overall, with the largest increase seen in the 66–70 y (5988 donors, 108.1% growth) group. Middle‐aged donors, aged 41–55 y, demonstrated a decrease of 16.5%. Over the last decade, the youngest age groups (16–40 y) comprised 61.3% of first‐time donors (FTD). Annual donation frequency increased with increasing age and PPP. The highest donation frequencies were seen in the oldest age groups. Conclusion Although the peak median age of APD increased over the study period, relative contribution of the 16–40 y APD base also increased. Older donors exhibited the highest donation frequencies and thus contributed the largest volume of apheresis platelet units. Platelet donor activity declined in the middle age (41–55 y) group.

“…One measure to maintain transfusion safety is the selection and exclusion of donors through clinical screening. This procedure aims to investigate epidemiological and behavioral aspects that no laboratory test is able to identify, which improves the safety in the search for volunteers and, consequently, the quality and safety of donated blood ( 7 , 8 ). Nonetheless, the rigidity of clinical screening based on current Brazilian rules and legislation can also be a limiting factor for blood donation ( 9 ).…”

IntroductionSociodemographic and behavioral factors are usually associated with the unsuitability to donate blood. Understanding the reasons behind the exclusion of blood bags is crucial for reducing donor deferral rates. This study aimed to characterize the profile of unsuitable donors in the Blood Center of the northern Brazilian state of Amazonas.MethodsThis is a retrospective study, based on documentary analysis of electronic medical records obtained in the Hematology and Hemotherapy Foundation of the state of Amazonas. This study included all individuals with complete medical records (n = 87,463) who tried to donate blood between 2017 and 2019.ResultsThe overall rate of donor unsuitability was 19.12% (n = 16,627) and the main reason was poor nutritional status (15.17%), followed by chronic health problems (11.40%), risky sexual behavior (9.5%) and exposure to risk (8.83%). High blood pressure figured as the leading cause of unsuitability among chronic health conditions (85.19%), while having sex with multiple partners (92.63%) was the main sexual risk behavior. The risk of exposure to malaria was responsible for 99.45% of unsuitability among those who were unsuitable due to exposure to risk factors. Deferral rates were associated with increasing age and replacement donation, which was the predominant type of donation. Women had the highest rates of unsuitability, mainly during the first donation (37.04%).DiscussionThis study provides the first known profile of blood donor unsuitability in the Brazilian Amazon and raises awareness of the region-specific needs that must be met to reduce blood donor unsuitability.
