The Landscape of Resource Utilization After Resuscitation of 22-, 23-, and 24-Weeks' Gestation Infants

Objective: To compare estimated healthcare resources needed to care for 22 through 24 weeks' gestation infants.

Study design: This multicenter, retrospective cohort study included 1505 live in-born and out-born infants 22 through 24 weeks' gestational age at delivery from 6 pediatric tertiary care hospitals from 2011 through 2020. Median neonatal intensive care unit (NICU) length of stay (LOS) for each gestational age was used as a proxy for hospital resource utilization, and the number of comorbidities and medical technology use for each infant were used as estimates of future medical care needs. Data were analyzed using Kruskal-Wallis with Nemenyi's posthoc test and Fisher's exact test.

Results: Of the identified newborns, 22-week infants had shorter median LOS than their 23- and 24-week counterparts due to low survival rates. There was no significant difference in LOS for surviving 22-week infants compared with surviving 23-week infants. Surviving 22-week infants had similar proportions of comorbidities and medical technology use as 23-week infants.

Conclusions: Compared with 23- and 24-week infants, 22-week infants did not use a disproportionate amount of hospital resources. Twenty-two-week infants should not be excluded from resuscitation based on concern for increased hospital care and medical technology requirements. As overall resuscitation efforts and survival rates increase for 22-week infants, future research will be needed to assess the evolution of these results.
