Hospitals across the PETAL Network implemented various combinations of operational changes. Steps included in this figure are limited to those implemented, not just planned at individual hospitals, including centralized triage systems, ICU and ward bed expansion, tiered staffing models, and alternative ventilator usage. The highest frequency of sites implemented only centralized triage processes. These changes are in addition to activation of an incident command center and elective procedure cancellation, which were in place at the majority of sites.
