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.
