Apheresis activity in Spain: a survey of the Spanish Apheresis Group

The Spanish Apheresis Group is a scientific association of physicians and nurses representing most of the medical centers in the country that are involved in apheresis. The group developed a survey in order to get information about the types and number of apheresis procedures performed in Spain. We received responses from 66 centers and we were able to collect data from at least one center of each autonomous region. There were 7 centers (11%) that did not perform any kind of apheresis procedures, 26 (39%) centers performed therapeutic apheresis procedures only, 18 (27%) centers performed apheresis donations only, and 15 (23%) centers performed both types of apheresis procedures. Regarding therapeutic apheresis in adult patients, plasma exchange (34%) and stem cell collections (30%) were the two therapeutic procedures most frequently reported, followed by erythrocytapheresis (13%) and extracorporeal photochemotherapy (11%). Regarding apheresis donation, our survey showed that the most frequent was multicomponent donation (45%) followed by plasmapheresis (28%) and single plateletapheresis (21%). When analyzing the current instrumentation for performing apheresis procedures, centers used the Spectra, Optia, and Trima devices (TerumoBCT) as the most frequent ones, followed by the MCS+(Haemonetics), Amicus (Fenwal), and Fresenius devices. In conclusion, we report here the first nationwide survey performed in Spain in order to get information about apheresis activities in our country. The survey is representative of Spain because we were able to collect data from at least one center from each of the different 17 autonomous regions, and we found a wide variety of therapeutic and donation procedures, as well as instrumentation used.
