Association of unit size, resource utilization and occupancy with outcomes of preterm infants

Objective:
Assess association of NICU size, and occupancy rate and resource utilization at admission with neonatal outcome.
Study Design:
Retrospective cohort study of 9978 infants born at 23-32 weeks gestation and admitted to 23 tertiary-level Canadian NICUs during 2010-2012. Adjusted odds ratios (AOR) were estimated for a composite outcome of mortality/any major morbidity with respect to NICU size, occupancy rate and intensity of resource utilization at admission.
Results:
A total of 2889 (29%) infants developed the composite outcome, the odds of which were higher for 16-29, 30-36 and >36-bed NICUs compared with <16-bed NICUs (AOR (95% CI): 1.47 (1.25-1.73); 1.49 (1.25-1.78); 1.55 (1.29-1.87), respectively) and for NICUs with higher resource utilization at admission (AOR: 1.30 (1.08-1.56), Q4 vs Q1) but not different according to NICU occupancy.
Conclusion:
Larger NICUs and more intense resource utilization at admission are associated with higher odds of a composite adverse outcome in very preterm infants.

A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
