Noninvasive Respiratory Support or Intubation during Stabilization after Birth and Neonatal and Neurodevelopmental Outcomes in Infants Born Preterm at 23-25 Weeks of Gestation.

OBJECTIVE: To examine the association between noninvasive respiratory support (NRS) or tracheal intubation (TI) during stabilization in infants born at 23-25 weeks of gestation and severe brain injury (sBI) or death, and significant neurodevelopmental impairment (sNDI). STUDY DESIGN: A retrospective cohort study of infants born at 23°/7-256/7 weeks of gestation in Canada. We compared infants successfully managed with NRS or TI during 30 minutes after birth. The primary outcomes were sBI or death before discharge, and sNDI among survivors with follow-up data at 18-24 months corrected age. The associations between exposures and outcomes were assessed using logistic regression models, and propensity score-matched analyses. RESULTS: The mean (SD) of gestational age and birth weight were 24.6 (0.6), 24.3 (0.7) weeks [P < .01], and 757 (173), 705 (130) grams [P < .01] in the NRS, and tracheal intubation (TI) groups, respectively, and 77% of infants in the NRS group were intubated by 7 days of age. sBI or death occurred in 25% (283/1118), and 36% (722/2012) of infants in the NRS and TI groups, respectively (aOR and 95% CI 0.74 [0.60, 0.91]). Among survivors with follow-up data, sNDI occurred in 17% (96/551), and 23% (218/937) of infants in the NRS and TI groups, respectively (aOR [95% CI] 0.77 [0.60, 0.99]). In the propensity score-matched analyses (NRS vs TI), results were consistent for sBI or death (OR [95% CI] 0.72 [0.60, 0.86]), but not for sNDI (OR [95% CI] 0.78 [0.58, 1.05]). CONCLUSIONS: Infants born at 23-25 weeks who were successfully managed with NRS, compared with TI, in the first 30 minutes after birth had lower odds of sBI or death before discharge, but had no significant differences in neurodevelopmental outcomes among survivors.

Process and Outcome Measures for Infants Born Moderate and Late Preterm in Tertiary Canadian Neonatal Intensive Care Units.

OBJECTIVE: To describe the prevalence of and between-center variations in care practices and clinical outcomes of moderate and late preterm infants (MLPIs) admitted to tertiary Canadian neonatal intensive care units (NICUs). STUDY DESIGN: This was a retrospective cohort study including infants born at 320/7 through 366/7 weeks of gestation and admitted to 25 NICUs participating in the Canadian Neonatal Network between 2015 and 2020. Patient characteristics, process measures represented by care practices, and outcome measures represented by clinical in-hospital and discharge outcomes were reported by gestational age weeks. NICUs were compared using indirect standardization after adjustment for patient characteristics. RESULTS: Among 25 669 infants (17% of MLPIs born in Canada during the study period) included, 45% received deferred cord clamping, 7% had admission hypothermia, 47% received noninvasive respiratory support, 11% received mechanical ventilation, 8% received surfactant, 40% received antibiotics in the first 3 days, 4% did not receive feeding in the first 2 days, and 77% had vascular access. Mortality, early-onset sepsis, late-onset sepsis, or necrotizing enterocolitis occurred in <1% of the study cohort. Median (IQR) length of stay was 14 (9-21) days among infants discharged home from the admission hospital and 5 (3-9) days among infants transferred to community hospitals. Among infants discharged home, 33% were discharged on exclusive breastmilk and 75% on any breastmilk. There were significant variations between NICUs in all process and outcome measures. CONCLUSIONS: Care practices and outcomes of MLPIs varied significantly between Canadian NICUs. Standardization of process and outcome quality measures for this population will enable benchmarking and research, facilitating systemwide improvements.

Variations in Site-Specific Costs for Infants Born Extremely Preterm in Canadian Neonatal Intensive Care Units.

OBJECTIVE: To quantify site-specific costs and their association with survival without major morbidity (SWMM) in Canada for neonates <28 weeks of gestation admitted to large tertiary neonatal intensive care units. METHODS: We conducted a retrospective analysis of infants born at <28 weeks of gestation and admitted to Canadian Neonatal Network sites from 2010 through 2021. Sites that cared for at least 50 eligible infants by gestational age in weeks over the study period were included. Using a validated costing algorithm that assessed physician, nursing, respiratory therapy, diagnostic imaging, transfusions, procedural, medication, and certain indirect costs, we calculated site and resource-specific costs in 2017 Canadian dollars (CAD) and evaluated their relationship with SWMM. RESULTS: Seven sites with 8180 (range 841-1605) eligible neonates with a mean (SD) gestation of 25.4 [1.3] weeks were included. Survival to discharge or transfer was 85.3% with a mean (SD) length of stay of 75 (46) days. The mean (SD) total and daily costs per neonate varied between $94 992 ($60 283) and $174 438 ($130 501) CAD and $1833 ($916) to $2307 ($1281) CAD, respectively. Between sites, there was no relationship between costs and SWMM. CONCLUSIONS: There was marked variation in costs and SWMM between sites in Canada with universal health care. The lack of concordance between both outcomes and costs among sites may provide possibilities for outcomes improvement and cost containment.
