Cost effective use of satellite packs in neonates: importance of birth weight

摘要

>Aim: To study transfusion requirements of premature infants in relation to their birth weight and thereby attempt to rationalise the method of dispensing satellite blood packs. >Method: Data on the distribution of neonatal transfusions with respect to weight were obtained retrospectively from unit A (51 infants, 168 transfusions) and unit B (46 infants, 151 transfusions). These data were used to model the effect of different policies on donor exposure and number of unused packs. >Results: Infants weighing less than 1000 g at birth have significantly higher transfusion requirements than those weighing1000 g or more (p = 0.001 (unit A), p = 0.004 (unit B)). Our model predicted a significant reduction in donor exposure if eight packs/infant were allocated to those weighing < 1000 g, and a significant cut in the number of unused packs if four satellite packs/infant were allocated to those weighing ⩾ 1000 g. >Conclusions: It would be safer and cost effective to allocate eight packs/infant to those with birth weights < 1000 g and four packs/infant to those with birth weights ⩾ 1000 g.
