Our older population: donors as well as recipients?

Background The upper age limit for blood donation differs in various countries, due to concerns about donor safety. In recent years, many countries have reviewed their policies regarding the upper age limits for donation. Evaluation of the impact of changing population and donor demographics may assist in better planning to meet future patient needs for blood. Aims We review current policies, evidence of the safety of donation in older individuals, and the contribution that older donors can make to the blood supply. Methods We reviewed policies in countries that are part of the Biomedical Excellence for Safer Transfusion Collaborative, and published studies on the safety of donation. We evaluated the contribution that older donors make to the blood supply at Canadian Blood Services. Results The upper age limit for regular whole blood donors ranges from 69–70 to 80; blood centres in several countries have recently removed the upper age limit, while many blood centres in the US have long had no upper age limit for donation. Data demonstrate that healthy older individuals can safely donate. Approximately 1·5% of all whole blood donations at Canadian Blood Services are made by donors past their 71st birthday. Summary/Conclusions There are more healthy older individuals than ever before. Many donors would like to continue donating into their eighth decade, and perhaps beyond. There is increasing evidence that donation is safe in older individuals, and that they can make a significant contribution to the blood supply.
