RESUMO
At the time of this study, the Sheba Medical Center Emergency Department (ED) in Israel had no formal triage system in place. To evaluate the interobserver reliability of two triage scales among nurses in our ED, the time-based Australasian Triage Scale (ATS) and the resource-based Emergency Severity Index (ESI), 10 nurses participated in a workshop on ATS and ESI. They then independently assessed 100 simulated triage scenarios taken from actual ED patients, and completed a survey. Intraclass correlation coefficients were calculated. The intraclass correlation coefficient for ATS was 0.64 (95% confidence interval: 0.57, 0.71), whereas for ESI, it was 0.52 (95% confidence interval: 0.45, 0.61). The nurses felt that ESI was slightly easier to use. Using conventional interpretations, the agreement for ATS is considered substantial, whereas that for ESI is considered moderate. Conversely, the nurses found the ESI somewhat easier to use.
