Determination of newborn special care bed requirements by application of queuing theory to 1975-1976 morbidity experience

The movement of newborn infants from the delivery room of a level III perinatal center to nursing units that provided different levels of care was prospectively documented for 1975 and 1976. These data were employed in a computer modeling experiment based on sequential queuing theory to determine the relationships between numbers of available intermediate and maximum care nursery beds, the probability that a given newborn arrival could not be accommodated, and the occupancy rates for each level of care. The nursery bed requirements for the level III center were used to estimate the number of special care beds needed by the regional Health Service Area.
