RESUMEN
BACKGROUND: Intraventricular hemorrhage (IVH) is a serious complication of premature (<32 weeks) deliveries, especially in very-low-birth-weight (VLBW; <1500 g) neonates. Infants developing severe IVH are more prone to long-term developmental disabilities. Although 62%-79% of women in Saudi Arabia receive antenatal steroids, IVH incidence remains high. We analyzed the risk factors for IVH in preterm VLBW neonates in the central region of Saudi Arabia. METHODS: We included premature infants with IVH (n = 108) and gestational age- and birth weight-matched control group infants (n = 108) admitted to our neonatal intensive care unit. Cases were divided into mild (grades I and II; n = 56) and severe (grades III and IV; n = 52) IVH groups. Association of IVH with risk factors in the first week of life was investigated. RESULTS: The following risk factors were associated with severe IVH: lack of antenatal steroid administration (P < .001), pulmonary hemorrhage (P = .023), inotrope use (P = .032), neonatal hydrocortisone administration (P = .001), and patent ductus arteriosus (PDA) (P = .005). Multivariable logistic regression analysis revealed the following to be significant: lack of antenatal dexamethasone (adjusted odds ratio [aOR]: 0.219, 95% confidence interval [95% CI] 0.087-0.546), neonatal hydrocortisone administration (aOR: 3.519, 95% CI 1.204-10.281), and PDA (aOR: 2.718, 95% CI 1.024-7.210). Low hematocrit in the first 3 days of life was significantly associated with severe IVH (all P < .01). CONCLUSIONS: Failure to receive antenatal dexamethasone, PDA, hydrocortisone administration for neonatal hypotension, and low hematocrit in the first 3 days of life was associated with severe IVH in VLBW neonates. Clinicians and healthcare policy makers should consider these factors during decision-making.
RESUMEN
BACKGROUND: Premature non-Saudi infants comprise a significant proportion of neonatal intensive care unit admissions in Saudi Arabia. Any differences in antenatal care of mothers and neonatal outcomes compared with premature Saudi infants are unreported. OBJECTIVE: Assess antenatal care of mothers and neonatal outcomes among premature Saudi and non-Saudi infants, and investigate possible reasons for disparities. DESIGN: Retrospective cohort study. SETTING: Tertiary care center in Riyadh. PATIENTS AND METHODS: All neonates of gestational age ≤32 weeks and birthweight <1500 g admitted from 2015 to 2019 were included. MAIN OUTCOME MEASURES: Antenatal care of mothers and rates of neonatal mortality and morbidity in premature Saudi and non-Saudi infants. SAMPLE SIZE: 755 premature infants, 437 (57.9%) Saudi, 318 (42.1%) non-Saudi. RESULTS: Saudi mothers received more antenatal steroids and were more likely to have gestational diabetes mellitus (P=.01 and .03, respectively). Non-Saudi mothers were more likely to have pregnancy-induced hypertension (P=.01). Non-Saudi infants had significantly higher rates of intraventricular hemorrhage, patent ductus arteriosus, pulmonary hemorrhage, bronchopulmonary dysplasia and necrotizing enterocolitis compared with Saudi infants (P=.03, <.001, .04, .002, and <.001, respectively). There were no significant differences in mortality rate, early-onset sepsis, and late-onset sepsis between Saudi and non-Saudi infants (P=.81, .81, and .12, respectively). CONCLUSIONS: Disparities exist in the antenatal care of Saudi and non-Saudi women and in the neonatal morbidities of their premature infants. There was no difference in the neonatal mortality rate. More quality improvement initiatives are required to reduce differences in antenatal and neonatal outcomes. LIMITATIONS: Retrospective, socioeconomic disparities not identified. CONFLICT OF INTEREST: None.
