Abnormal Vital Sign “Triggers” Do Not Improve Outcomes

Patients whose abnormal vital signs go unrecognized are at high risk for complications. The authors of the current study implemented a “trigger” program to bring immediate attention to emergency department patients whose initial vital signs are significantly abnormal. Overhead paging was used to call the attending and resident physicians, nurse, and technician immediately to the room of patients with heart rate <40 or >130, respiratory rate <8 or >30, systolic blood pressure <90 mm Hg, or oxygen saturation <90% on room air.

Researchers measured the program's impact by comparing hospital and intensive care unit lengths of stay, 30-day mortality, and the frequency of upgrades in care during the 1-year periods before and after program implement…
