INTERVAL Study: To Determine Whether the Interval Between Blood Donations in England Can be Safely and Acceptably Decreased

NCT01610635 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50000

Summary

It is hypothesised that the number of donations made by English blood donors will be greater with reduced vs. standard inter-donation intervals. The null hypothesis is that there will be no difference in donations between treatment groups; this may arise if reduced inter-donation intervals result in a greater number of donation deferrals (due to low haemoglobin) and/or an unacceptable burden to donors.

Conditions

  • Blood Donation

Interventions

OTHER

Over a period of two years participants will be invited to give blood either at usual donation intervals or more frequently. Men will be invited to donate every 12, 10 or 8 weeks and women every 16, 14 or 12 weeks.
