Accuracy of emergency severity index of triage in Imam Hossein hospital - Tehran, Iran (2011)

Background and Objective: Triage is the most important and the first stage of patient’s management at the time of arrival to hospital emergency department. Emergency severity index (ESI) is a common triage system worldwide. This study was aimed to evaluate the accuracy of ESI in emergency department of Imam Hossein hospital in Tehran, Iran. Materials and Methods: In this descriptive study the result of patients’ triage based on ESI were gathered for all patients referred to emergency department of Imam Hossein Hospital from January to April 2011. A questioner was filled for each patient by the nurse and a emergency specialist independently. The l for the degree of agreement of triage between nurse and clinician was 81% (95% CI: 0.79-0.83). The sensivity of triage for step I, II, III, IV and V were 100%, 53.2%, 90.7%, 67.1% and 98% respectively. The specificity of triage for step I, II, III, IV and V were 99.8%, 97.5%, 93.7%, 98.3% and 94% respectively. There was a significant overlapping between the triage step and the patient clinical outcome. Conclusion: This study showed that five steps triage contain a high accuracy and estimation of patient outcomes

Moth Swarm Algorithm Based Approach for the ACOPF Considering Wind and Tidal Energy

International Conference on Artificial Intelligence and Applied Mathematics in Engineering (ICAIAME) -- APR 20-22, 2019 -- Antalya, TURKEYIn the last decades, optimal power flow (OPF) problem is becoming one of the most important nonlinear and non-convex problems for the planning and operation of large-scale modern electrical power grids. In this study, the OPF problem with the consideration of two types of renewable energy sources (RES), tidal and wind energy, is studied. The Gumbel PDF is used to calculate power output of tidal energy. The proposed OPF problem is solved by Moth Swarm Algorithm (MSA), and tested on an IEEE 30-bus test system via two different cases with and without the consideration of prohibited operating zones. The simulation results show the effectiveness of the MSA based OPF approach.Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [BIDEB 2219, 1059B191700888]Dr. Serhat DUMAN would like to thanks the support provided by Scientific and Technological Research Council of Turkey (TUBITAK) BIDEB 2219 Postdoctoral Research Program under application number 1059B191700888.WOS:0006787710000722-s2.0-8508342366
