Evaluation of the relationship between day or night birth time and morbidities and mortality in premature infants less than 32 weeks in a Turkish NICU.

This study investigated whether the time of birth—during daytime working hours versus nighttime, weekends, and public holidays—affects the clinical outcomes of premature infants born before 32 weeks of gestational age in a neonatal intensive care unit (NICU) in Turkey. Analyzing data from 572 infants, the study found no significant differences in morbidity or mortality between infants born during on-hours and off-hours, despite a ninefold increase in physician workload during off-hours and consistent nurse-to-patient ratios. The findings suggest that standardized, experienced neonatal care can mitigate potential risks associated with reduced staffing or fatigue during off-hours. The authors emphasize that each NICU should assess the impact of birth timing on outcomes within their specific care context, noting particular relevance for low- and middle-income countries where staffing and resources may be more limited.
