Post-hurricane fluid conservation measures fail to reduce IV fluid use in critically ill children.

Background: There are risks associated with excessive intravenous fluid (IVF) administration in critically ill children. Previous efforts have described opportunities to reduce positive cumulative fluid balance (CFB) in this population but have not been widely implemented. In the wake of Hurricane Helene, a national IVF shortage led to the implementation of IVF conservation guidelines. We sought to determine if this was associated with a reduction in IVF use and CFB.

Methods: The present study is a four-site cohort study of critically ill children utilizing a federated data collection framework to extract patient age, sex, weight, and daily fluid intake/output for days 1-4 of all admissions 28 days prior to and 28 days after the implementation of IVF conservation guidelines. Guidelines were individualized per institution. Total fluid intake, total IVF intake, % intake from IVF, and % CFB were compared between pre- and post-IVF conservation groups.

Results: All sites had similar conservation recommendations. There were 633 patients admitted pre- and 619 patients admitted post-IVF conservation guideline implementation, with similar age and weight distributions. There was no significant difference in IVF use pre- and post-IVF conservation; 29-35% of patients had > 5% CFB on day 1 pre-IVF conservation while 27-39% did post-conservation, with increasing numbers on day 2.

Conclusions: Even in the setting of a national IVF shortage, simple recommendations without structured change were insufficient to change IVF administration practices. This indicates additional practices will be needed to reduce IVF intake and % CFB in this vulnerable population.
