Emergency Medical Services (EMS) is a critical component of our nation's emergency and trauma care system, providing response and medical transport to millions of sick and injured Americans each year. At its best, EMS is a crucial link to survival in the chain of care, but within the last several years, complex problems facing the emergency care system have emerged. Press coverage has highlighted instances of slow EMS response times, ambulance diversions, trauma center closures, and ground and air medical crashes. This heightened public awareness of problems that have been building over time has underscored the need for a review of the U.S. emergency care system. Emergency Medical Services provides the first comprehensive study on this topic. This new book examines the operational structure of EMS by presenting an in-depth analysis of the current organization, delivery, and financing of these types of services and systems. By addressing its strengths, limitations, and future challenges this book draws upon a range of concerns: • The evolving role of EMS as an integral component of the overall health care system. • EMS system planning, preparedness, and coordination at the federal, state, and local levels. • EMS funding and infrastructure investments. • EMS workforce trends and professional education. • EMS research priorities and funding. Emergency Medical Services is one of three books in the Future of Emergency Care series. This book will be of particular interest to emergency care providers, professional organizations, and policy makers looking to address the deficiencies in emergency care systems.
Based on careful analysis of burden of disease and the costs ofinterventions, this second edition of 'Disease Control Priorities in Developing Countries, 2nd edition' highlights achievable priorities; measures progresstoward providing efficient, equitable care; promotes cost-effectiveinterventions to targeted populations; and encourages integrated effortsto optimize health. Nearly 500 experts - scientists, epidemiologists, health economists,academicians, and public health practitioners - from around the worldcontributed to the data sources and methodologies, and identifiedchallenges and priorities, resulting in this integrated, comprehensivereference volume on the state of health in developing countries.
Catastrophic disasters occurring in 2011 in the United States and worldwide-from the tornado in Joplin, Missouri, to the earthquake and tsunami in Japan, to the earthquake in New Zealand-have demonstrated that even prepared communities can be overwhelmed. In 2009, at the height of the influenza A (H1N1) pandemic, the Assistant Secretary for Preparedness and Response at the Department of Health and Human Services, along with the Department of Veterans Affairs and the National Highway Traffic Safety Administration, asked the Institute of Medicine (IOM) to convene a committee of experts to develop national guidance for use by state and local public health officials and health-sector agencies and institutions in establishing and implementing standards of care that should apply in disaster situations-both naturally occurring and man-made-under conditions of scarce resources. Building on the work of phase one (which is described in IOM's 2009 letter report, Guidance for Establishing Crisis Standards of Care for Use in Disaster Situations), the committee developed detailed templates enumerating the functions and tasks of the key stakeholder groups involved in crisis standards of care (CSC) planning, implementation, and public engagement-state and local governments, emergency medical services (EMS), hospitals and acute care facilities, and out-of-hospital and alternate care systems. Crisis Standards of Care provides a framework for a systems approach to the development and implementation of CSC plans, and addresses the legal issues and the ethical, palliative care, and mental health issues that agencies and organizations at each level of a disaster response should address. Please note: this report is not intended to be a detailed guide to emergency preparedness or disaster response. What is described in this report is an extrapolation of existing incident management practices and principles. Crisis Standards of Care is a seven-volume set: Volume 1 provides an overview; Volume 2 pertains to state and local governments; Volume 3 pertains to emergency medical services; Volume 4 pertains to hospitals and acute care facilities; Volume 5 pertains to out-of-hospital care and alternate care systems; Volume 6 contains a public engagement toolkit; and Volume 7 contains appendixes with additional resources.
In tiered emergency medical services (EMS) systems involving multiple types of response vehicles, how to match the resource to patients is a critical issue. Responses to emergency patients must be both prompt and capable of providing the type of services that patients require. I propose four discrete optimization models that design EMS systems to achieve both objectives. This dissertation begins by studying the cutoff priority scheme, which gives priority to more emergent calls for service when the system is congested by reserving vehicles exclusively for high priority calls. I propose an iterative framework composed of a spatial queuing approximation model and a Mixed Integer Linear Program that evaluates and designs public safety systems with a cutoff priority scheme. I identify the trade-off between improving the expected coverage for high priority calls at the expense of losing more low priority calls. Next, I focus on emergency responses on a congested network with two types of ambulances. I formulate a Markov decision process model that determines which type of ambulance to send to patients in real-time based on the number of idle ambulances. Structural properties of the optimal policy are derived to characterize the optimal assignment strategy and maintain computational tractability. I show the conditions under which there exists an optimal policy that is a class separable, signal threshold type and a state control limit type policy. Furthermore, I extend the decision context of the earlier model to a tandem queueing approach. The new model separates response phase and the transport phase, to study various options of dispatch, such as sending multiple vehicles to a single call (multiple response) or non-transport vehicles. Lastly, I propose a scenario-based approach focusing on a tiered EMS system with two types of ambulances which often employ multiple response. I formulate a two-stage stochastic programming model that deploy ambulances in the first stage and dispatch them to prioritized emergency patients in the second stage. The value of the stochastic solution is demonstrated with a case study and a simulation analysis. I propose a computationally effective solution method based on Benders cuts to solve large-scale instances.
Cardiac arrest can strike a seemingly healthy individual of any age, race, ethnicity, or gender at any time in any location, often without warning. Cardiac arrest is the third leading cause of death in the United States, following cancer and heart disease. Four out of five cardiac arrests occur in the home, and more than 90 percent of individuals with cardiac arrest die before reaching the hospital. First and foremost, cardiac arrest treatment is a community issue - local resources and personnel must provide appropriate, high-quality care to save the life of a community member. Time between onset of arrest and provision of care is fundamental, and shortening this time is one of the best ways to reduce the risk of death and disability from cardiac arrest. Specific actions can be implemented now to decrease this time, and recent advances in science could lead to new discoveries in the causes of, and treatments for, cardiac arrest. However, specific barriers must first be addressed. Strategies to Improve Cardiac Arrest Survival examines the complete system of response to cardiac arrest in the United States and identifies opportunities within existing and new treatments, strategies, and research that promise to improve the survival and recovery of patients. The recommendations of Strategies to Improve Cardiac Arrest Survival provide high-priority actions to advance the field as a whole. This report will help citizens, government agencies, and private industry to improve health outcomes from sudden cardiac arrest across the United States.
