Our mitigation strategy decreased fluid usage per case, related costs, and plastic waste generated from fluids and infusion tubing.
Study context

- Patients cared for in the included operating rooms, October 2023 to January 2025, during the 2024 nationwide IV fluid shortage caused by Hurricane Milton
- Participants
- 46,893 patients
- Exposure
- After vs Before
- Outcome
- Weekly fluid delivery requirements per case
