OBJECTIVE: To investigate the factors that influence the length of stay (LOS) in a neonatal intensive care unit (NICU).
METHODS: This retrospective study analysed clinical data from all newborns hospitalized in the NICU of a tertiary hospital in the Western Hunan area of China over a 9-year period (2012-2020). Factors associated with the LOS were analysed using univariate analysis and Cox regression analysis.
RESULTS: A total of 16 094 newborns were included in the study: of which 9615 were inborn and 6479 were outborn newborns. There were 9482 males and 6612 females. Over the 9-year period, the mean LOS was 11.08 days (median LOS, 9.00 days; range, 1-141 days); and the LOS first increased, then decreased and stabilized. A LOS of 8-28 days was the most common duration (8849 of 16 094; 54.98%). Cox regression analysis demonstrated that sex, patient source, delivery method, gestational age, birth weight and comorbidities were significantly associated with LOS.
CONCLUSION: Being male, low gestational age and low birth weight increased the LOS. Reducing preterm and post-term infants, as well as eliminating comorbidities, could effectively shorten the LOS of newborns.
