Cost efficiency of neonatal nurseries: the significance of unit size.

The cost of neonatal intensive care is high, and human and financial resources are finite. It is therefore essential to provide such care efficiently in terms of costs while still maintaining standards of care. We looked at the relationship of unit size to cost and determined the optimum and minimum size of the unit in terms of cost efficiency. Our data suggest that units with fewer than 6 ventilator cots were less cost-efficient than those with more cots while those with 12 ventilator cots were the most efficient. The calculations were done only up to 16 ventilator cots. Similarly, level II units were most cost-efficient when attached to an intensive care unit and had over 16 cots.
