The registry continued to grow in 2022, though not as rapidly as in past years, one reason being a dearth of enquiries about patient events and appeals this year. Another is the increase in the number of registered donors removed from the registry when they turn 60, which is done due to patient safety concerns. Moreover, our marketing efforts are now targeted more strongly on the young, male target group with the aim of promoting qualitative growth.
The Swiss registry listed 177,849 persons at the end of 2022; a 5.9 per cent increase over 2021 (171,709 persons). The number of persons who registered as blood stem cell donors was 8,138. This is below the 2021 figure (12,188 new registrations) but is still a stable level of growth. In 2022, 2,005 persons were removed from the registry (2021: 2,645). In addition to the regular removal of donors from the registry when they turn 60, this figure includes individuals who had themselves removed from the registry because a change in their health or private situation had made them unable to donate blood stem cells. Through the intensified dialogue aimed at strengthening donor commitment, registered donors are regularly reminded about their pledge to donate blood stem cells and have occasion to review it, quickly and easily, and decide whether they wish to remain in the registry. This results in better quality and, thus, in the readiness of registered donors to respond positively if and when a concrete request for a donation comes in.
The percentage of registrations initiated online fell somewhat in 2022 compared to 2021. This is because it became possible to hold in-person registration events again in the second half of 2022; this was never an option in pandemic-fraught 2021. Of the total new registrations, 87.7 per cent were carried out using the online questionnaire (2021: 96.8 per cent).
