During a five years period the participating transfusion medicine establishments will report all their non-trivial adverse events (AE) occurring during preparative hemaphereses. Complications may be related to the blood donors, the blood products, the disposables or the apheresis devices. The study hypothesis regarding each participating center is that their procedure-related AE rate is not higher than the respective rate of all other centers in total.

Condition Intervention
Blood Donation With Hemapheresis
Other: blood donation

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Open Prospective Multi-national Long-term Study to Register Adverse Events Related to Hemaphereses by Means of an Internet-based Haemapheresis Vigilance Questionnaire

Further study details as provided by DGTI - Haemapheresis Vigilance Working Party:

Primary Outcome Measures:
  • Assessment of all non-trivial adverse events (AE) occurring during hemapheresis [ Time Frame: up to one year ]
    All non-trivial AEs will be recorded regardless of whether anticipated products have been collected or not

Secondary Outcome Measures:
  • Rate of products per apheresis [ Time Frame: hemapheresis stay: expected time range from 1 hour for plasmaphereses to 5 hours for stem cell aphereses ]
    amount of obtained products vs. anticipated products

Estimated Enrollment: 50000
Study Start Date: February 2012
Estimated Study Completion Date: February 2017
Estimated Primary Completion Date: February 2017 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
healthy apheresis donors
healthy blood donors for blood cell aphereses
Other: blood donation
blood donation with preparative hemapheresis

Detailed Description:
In the scope of this study the participating transfusion medicine establishments obligate themselves to record all significant Adverse Events (AE) related to preparative hemaphereses of healthy donors. All complications (phlebotomy and circulation problems, citrate toxicity, donor compliance, and technical complications) shall be assessed with respect to plasma-, platelet-, leukocyte- (stem cells, granulocytes, monocytes), and red cell aphereses as well as multicomponent aphereses. Study data are recorded by means of an Internet-based hemapheresis vigilance system. Study results will be evaluated according to the advanced standards of the International Haemovigilance Network (IHN). The study contributes to the quality assurance of each single center as it enables the comparison to other transfusion medicine establishments.
