Emergency Response Time and pre hospital trauma survival rate of the national ambulance service greater accra january december 2014
BMC Emergency Medicine, 2018Co-Authors: Mohammednajeeb Mahama, Ernest Kenu, Delia Akosua Bandoh, Ahmed Nuhu ZakariahAbstract:Every year, about 1.2 million people die through road traffic crashes worldwide. Majority of these deaths occur in Africa where most of their Emergency medical services are underdeveloped. In 2004, Ghana established the National Ambulance Council to provide Timely and efficient pre-hospital Emergency medical care to the sick and injured. Pre-hospital Emergency medical service is essential for accident victims since it has the potential of saving lives. The study sought to determine the relationship between pre-hospital trauma survival rate and Response Time to emergencies and factors associated to pre-hospital trauma survival in Accra, Ghana. The study was a cross sectional study which reviewed pre-hospital care forms of trauma patients from the fourteen ambulance stations in the Greater Accra region from January to December 2014. Data were extracted from these forms and the Response Time estimated. Conscious patients who were alert were categorized as responsive under the AVPU scale. The proportion of patients who survived pre-hospital trauma and the Time pre-hospital trauma cases were responded to was estimated. Multiple logistic regression analysis was conducted to determine which variables were associated with survival. A total of 652 pre-hospital care forms were reviewed. About 87% survived pre-hospital trauma. The average Response Time to patients was (16.9 ± 0.7) minutes and the median transportation Time of the patient was 82 min. Level of consciousness of a patient and Response Time of patients transported was found to be significantly associated with pre-hospital trauma survival. There was a high trauma patient survival rate among victims attended to by an NAS. The average Response Time in Greater Accra region in the 14 ambulance stations is 16.9 min which is not different from the 17 min recorded in 2013 by NAS. Factors that were associated with pre-hospital survival were alertness in the level of consciousness and Response Time less than 17 min.

accurate passive location estimation using toa measurements
IEEE Transactions on Wireless Communications, 2012Co-Authors: Junyang Shen, Andreas F Molisch, J SalmiAbstract:Localization of objects is fast becoming a major aspect of wireless technologies, with applications in logistics, surveillance, and Emergency Response. Time-of-arrival (TOA) localization is ideally suited for high-precision localization of objects in particular in indoor environments, where GPS is not available. This paper considers the case where one transmitter and multiple, distributed, receivers are used to estimate the location of a passive (reflecting) object. It furthermore focuses on the situation when the transmitter and receivers can be synchronized, so that TOA (as opposed to Time-difference-of-arrival (TDOA)) information can be used. We propose a novel, Two-Step estimation (TSE) algorithm for the localization of the object. We then derive the Cramer-Rao Lower Bound (CRLB) for TOA and show that it is an order of magnitude lower than the CRLB of TDOA in typical setups. The TSE algorithm achieves the CRLB when the TOA measurements are subject to small Gaussian-distributed errors, which is verified by analytical and simulation results. Moreover, practical measurement results show that the estimation error variance of TSE can be 33 dB lower than that of TDOA based algorithms.

Emergency Response Time after out of hospital cardiac arrest
European Journal of Internal Medicine, 2011Co-Authors: Andjelic Sladjana, Panic Gordana, Sijacki AnaAbstract:Abstract Objectives To investigate the Emergency Response Time after out-of-hospital cardiac arrest (OHCA) in four cities in Serbia. Methods A prospective, two-year, multicenter study was designed. Using the Utstein template we recorded out-of-hospital CPR (OHCPR) and analyzed the Time sequence segment of the variables in OHCA and CPR gold standards. Multivariable logistic regression models were developed using Emergency Response Time as the primary independent variable and survival to return of spontaneous circulation (ROSC), survival to hospital discharge (HD), and one-year survival (1y) as the dependent variable. ROC curves represent cut off Time dependent survival data. Results During the study period, the median Time of recognition OHCA was 5.5 min, call receipt was 1 min and the call–Response interval was 7 min. The median Time required to verify OHCA and ALS onset was 10 min. ALS was carried on for 30.5 min (SD = 21.3). Abandonment of further CPR/death occurred after 29 min. The first defibrillation shock was performed after 13.3 ± 9.0 min, endotracheal tube was placed after 16.8 ± 9.4 min and the first adrenaline dose was injected after 18.9 ± 9.3 min. Higher survival (ROSC, HD, 1y) rate was found when CPR is performed within the first 4 min after OHCA. Conclusion The Emergency Response Time within 4 min was associated with improved survival to ROSC, HD and 1y after OHCA. Despite the fact that our results are in accordance with the findings published in other papers, there is still a need to take all appropriate measures in order to decrease the Emergency Response Time after OHCA.
