CONTEXT Previous studies have reported that the number and distribution of trauma centers are uneven across states, suggesting large differences in access to trauma center care. OBJECTIVE To estimate the proportion of US residents having access to trauma centers within 45 and 60 minutes. DESIGN AND SETTING Cross-sectional study using data from 2(More)
The location of base stations (BS) and the allocation of channels are of paramount importance for the performance of cellular radio networks. Also cellular service providers are now being driven by the goal to enhance performance, particularly as it relates to the receipt and transmission of emergency crash notification messages generated by automobile(More)
BACKGROUND In 2006, the Centers for Disease Control and Prevention (CDC) released a revised Field Triage Decision Scheme. It is unknown how this modified scheme will affect the number of patients identified by emergency medical services (EMS) for transport to a trauma center. OBJECTIVES To determine the change in the number of patients transported by EMS(More)
OBJECTIVE To determine the accuracy of emergency medical services (EMS) provider assessments of motor vehicle damage when compared with measurements made by a professional crash reconstructionist. METHODS EMS providers caring for adult patients injured during a motor vehicle crash and transported to the regional trauma center in a midsized community were(More)
The Atlas and Database of Air Medical Services (ADAMS) is a web-based, password-protected, geographic information system containing data on air medical service main and satellite base helipads, communication centers, rotorwing aircraft, and major receiving hospitals for trauma in the United States. ADAMS initially was developed to provide the geographic(More)
OBJECTIVE To determine the predictive value of the mechanism-of-injury step of the American College of Surgeons Field Triage Decision Scheme for determining trauma center need. METHODS Emergency medical services (EMS) providers caring for injured adult patients transported to the regional trauma center in three midsized communities over two years were(More)
OBJECTIVE Our objective was to determine the predictive value of the anatomic step of the 2011 Field Triage Decision Scheme for identifying trauma center need. METHODS Emergency medical services (EMS) providers caring for injured adults transported to regional trauma centers in three midsized communities were interviewed over two years. Patients were(More)
In this paper, a tour-based multi-objective logistics model for optimized scheduling of the delivery of critical items in a disaster relief operation is proposed. Our model considers multi-items, multi-vehicles, multi-periods, and a split delivery scenario in a disaster. Two heuristic approaches are introduced to solve the logistics problem. In the first(More)
The use of an automated collision notification (ACN) device in vehicles can greatly reduce the time between crash occurrence and notification of emergency medical services (EMSs). Most ACN devices rely on cellular technology to report important crash information to the proper authorities. The objective of this study was to examine the ability of the(More)
