ObjectiveTo determine the reliability of vital signs measured at triage in the emergency department.MethodsThe vital signs of all consenting ambulatory patients 16 years old and above presenting at triage were measured by the duty triage nurse as standard practice and then repeated by a single, blinded, trained observer within 2 min of the initial assessment using the same (manual or electronic) methods. The results were analysed using paired sample t-tests.ResultsNo significant difference was found in the repeated electronic measurement of oxygen saturation [95% confidence interval (CI) -0.30-0.46, P=0.687] or repeated manual measurement of respiratory rate (95% CI -1.04-1.76, P=0.613). A statistically but not clinically significant difference of 2.43 bpm was found in the repeated electronic measurement of heart rate (95% CI 0.52-4.33, P=0.013).ConclusionsThe manual and electronic measurements of vital signs at triage appear to be reliable.
