Criteria for blood transfusions.

A review of the use of blood transfusions used in a small community hospital over a two-year period revealed a high incidence of instances in which the clinical record did not show essential need for the procedure. Educational efforts in hospital staff meetings resulted in some improvement in this respect during the two-year period. Of single unit transfusions given during the first year, 80 per cent were deemed to have been nonessential; during the second year, 52 per cent. Methods which will reduce the use of blood except when it is essential are (1) continuation of staff education; (2) providing the staff with accurate methods of measurement of blood volume and of monitoring blood loss; (3) use of a separate blood transfusion chart in the patient's hospital record; and (4) establishment of a hospital transfusion committee to review the criteria in all cases in which blood is transfused.
