Objective: This study aimed to compare the short-term outcomes of infants from our level IIIC neonatal intensive care unit in 2 different periods.

Materials and Methods: In this cohort study, data from preterm infants (≤29 weeks and birth weight <1500 g) registered in the Vermont Oxford Network system were divided into 2 periods, the first period between January 1, 2005, and December 31, 2009, and the second between January 1, 2010, and December 31, 2019.

Results: There was no difference in the distribution of preterm infants according to their gestational age subgroups (P = .169). Although the survival rate increased significantly in the second period (48.1% vs. 64.3% (P < .001), there was no difference in terms of survival without morbidity (P = .480). The frequency of antenatal care (P < .001), antenatal maternal steroid use (P < .001), cesarean section (P = .025), and small for gestational age (P < .003) increased in the second period. Surfactant treatment in the delivery room (P < .003), neonatal intensive care unit (P < .001), and nasal continuous positive airway pressure use before intubation as a part of initial resuscitation (P < .001), nosocomial infections (P = .001), patent ductus arteriosus requiring medical treatment (P = .011), and necrotizing enterocolitis (P = .014) were significantly more common, but early neonatal sepsis (P = .002) and discharge home with only formula (P = .010) were less in the second period.

Conclusion: Differences were noted in the prognosis and treatment choices of preterm infants in the same unit between 2 periods. The analysis of neonatal intensive care unit data, through rigorous methods, may provide opportunities for the development of quality improvement projects to improve the quality of health care in developing countries.
