G. Joshi et al., ROLE OF QUALITY ASSESSMENT IN IMPROVING RED-BLOOD-CELL TRANSFUSION PRACTICE, Irish journal of medical science, 166(1), 1997, pp. 16-19
A prospective analysis of perioperative red blood cell transfusion pra
ctice in 110 patients undergoing elective primary total hip arthroplas
ty was conducted as a part of a quality assessment programme at the Na
tional Orthopaedic Hospital. In addition to demographic and clinical d
ata, blood loss and perioperative transfusions were also recorded, Blo
od was collected for evaluation of haematocrit levels at predetermined
intervals (preoperative and 6 h, 1, 2, 3, 7 days, postoperatively). B
lood transfused with the patient's haematocrit of more than 30 per cen
t was considered inappropriate, In addition, a discharge haematocrit e
xceeding 36 per cent was chosen to identify overtransfusion. Eighty-fo
ur per cent were transfused a total of 191 units of homologous blood,
Only 4 units were transfused between 3 patients, intraoperatively, All
intraoperative transfusions were appropriate, Using the preset criter
ia (i.e. blood transfused with haematocrit of more than 30 per cent),
36 per cent of total units transfused were inappropriate, Using the cr
iterion of discharge haematocrit of more than 36 per cent, 24 per cent
of the patients were overtransfused. As compared to a previous retros
pective analysis of blood transfusion in the same patient population w
hich showed that inappropriate transfusion occurred in 45 per cent of
the patients, the results from this study suggest a trend towards a mo
re conservative transfusion practice, The improvement in transfusion p
ractice may be due to the ongoing quality assurance programme and the
use of transfusion guidelines.
