The blood centre as a community health resource

Abstract

Blood centres in the USA encounter over 35 000 blood donors every day, a number that is far exceeded worldwide. This daily encounter of thousands of people with the healthcare system offers an unusual opportunity for blood centres to engage these donors in ways that contribute to individual and community health. In addition, a positive interaction at the blood centre may encourage donors to return more often, thus enhancing the blood supply. The wealth of medical information gathered by blood centres also presents an opportunity for epidemiological studies of health and illness that affect the community at large. Donors receive a 'mini-physical' as part of the donor qualification process. Required procedures include blood pressure measurement and haemoglobin determination. Targeted education, counselling and referral of donors with hypertension and/or low haemoglobin engages them in the care of critical personal health issues. Carbonyl iron supplied to female donors of child-bearing age replaces iron lost in the donation and can retain them as active blood donors. A range of optional screening tests and procedures offer enhanced interactions between the donor and the blood centre. Inexpensive tests, such as cholesterol and random blood glucose determination, can detect abnormalities that may initiate further medical interventions to address cardiovascular and diabetic risks. These enhanced medical interactions with donors must be undertaken with care and appropriate medical supervision. However, the opportunity, indeed the responsibility, to act on important medical information enhances the range of medical support for donors and is an opening for blood centres to expand their involvement in the health of the community. © 2006 Blackwell Publishing.
