Multicenter Study Comparative Study
Analysis of medical emergency team calls comparing subjective to "objective" call criteria.
To explore the reasons why nursing staff use the subjective "worried" Medical Emergency Team (MET) calling criterion and compare the outcomes of calls activated using the "worried" criterion with those calls activated using "objective" criteria such as vital sign abnormalities. ⋯ The "worried" criterion was the most frequent reason for MET calls, implying a high degree of empowerment and independent action by nursing staff. Low SpO2 and respiratory distress were the most common causes for concern. There was a significant difference between MET calls triggered by "worried" criteria and "objective" criteria for outcomes immediately following MET (p < 0.001). Further assessment and refinement of MET triggers particularly in relation to respiratory distress and pulse oximetry may be needed.
