The Editor,

We read with interest the article on blood transfusion by Scott et al. [1] Low haematocrit on cardio pulmonary bypass (CPB) (<22%), which is independently associated with stroke, myocardial infarction (MI), renal failure, prolonged ventilation, sepsis, reoperation due to bleeding, [2],[3] has not been taken into consideration. The discussion could have been more detailed, such as attempting to explain why patients with cerebro vacular accident (CVA) and chronic obstructive pulmonary disease (COPD) had higher transfusion rates.

Linear regression showed increased resource utilisation in all transfused patients and in 263 patients with "no preoperative morbidity", which led to the conclusion that transfusion is an independent predictor of resource utilisation.

The authors included only MI, diabetes mellitus, hypertension, congestive heart failure, and renal failure in "no preoperative morbidity" patients and not female sex, preoperative haematocrit, COPD, CVA, and peripheral vascular disease, which significantly affect resource utilisation. [2] Surgical data such as longer CPB time, increased intra artic baloon pump use, bleeding requiring reoperation, postoperative renal failure, postoperative CVA are independently associated with higher resource utilisation, [2] and Table 1 and Table 2 show a significant difference between the transfused and non-transfused patients. We are of the opinion that it would be incorrect to arrive at the derived conclusion without reference to these variables.
