Overview of the HEMO study

The Health Economics MOdelling of Blood Donation study (the HEMO study) aims to determine the cost-effectiveness of the different ways of maintaining the future supply of blood to the NHS. The  study brings together a team with experience in health economics, statistics, trial design, qualitative research, and strategic development of the blood service.blood donor


A reliable supply of blood and its products is essential to NHS care. NHS Blood and Transplant (NHSBT) is the main supplier of these products to the NHS. It is important to ensure that in the future, there will continue to be enough blood donated.

One way to increase the blood supply is to ask blood donors to give blood more frequently. However, some time is required between blood donations to allow the body to replace its iron stores. NHS Blood and Transplant (NHSBT) has funded the INTERVAL study involving about 50,000 blood donors, aiming to find the optimum interval for which it is safe for different donors to give blood.

In the HEMO study, we are aiming to answer three questions:patient icon

  • Will donors who have donated blood more often in the INTERVAL study be willing to continue giving blood more often in the future?
  • Are there other changes to the blood service that would encourage more frequent blood donations, such as different opening times?
  • What is the value for money of alternative strategies for maintaining the blood supply?
