The objectives of the study were to determine the most effective and reliable means of restraining children on an ambulance cot and to develop recommended field procedures for emergency medical service providers. A series of crash tests at 48 km/h were conducted using convertible child restraints, car beds, and harness systems tested with 3-year, infant, and 6-year size dummies. Belt configurat...

BACKGROUND Research on utilization of ambulances by pediatric patients lacks an objective, reproducible tool for the evaluation of patterns of ambulance use by both the providers and the users of this resource. OBJECTIVES 1) To develop an objective, diagnosis-based measure of appropriateness of ambulance utilization. 2) To use the measure to evaluate whether Municipal Ambulance Service dispat...

This article discusses different modelling approaches considered to address problems related to ambulances' location and relocation as well as dispatching decisions arising in Emergency Medical Services (EMS) management. Over the past 10 years, a considerable amount of research has been devoted to this field and specifically, to the development of strategies that more explicitly take into accou...

All patients brought to hospital by a special cardiac ambulance were followed up and compared with patients carried by routine ambulances to assess the effectiveness of a cardiac ambulance service. The overall mortality of patients with heart attacks was 51% among those carried by an ordinary ambulance and 40% among those carried by the cardiac ambulance. The apparently low mortality in the lat...

The work presented in this paper is based on two projects that were conducted at St. Olavs Hospital (Norway) when preparing for the COVID-19 pandemic. Three discrete event simulation models are provided to evaluate resource requirements during peak of First, we estimate number beds needed emergency department (ED). In second model, ambulances required maintain prepandemic response times patient...

BACKGROUND AND PURPOSE Intravenous tissue plasminogen activator improves outcome after ischemic stroke when given within 3 hours of symptoms onset in carefully selected patients. However, only a small proportion of acute stroke patients are currently eligible for thrombolysis, mainly because of excessive delay to hospital presentation. We sought to determine the factors associated with early ad...

In this study, two mathematical models have been developed for assigning emergency vehicles, namely ambulances, to geographical areas. The first model, which is based on the assignment problem, ambulance transfer (moving ambulances) between locations has not considered. As can improve system efficiency by decreasing response time as well operational cost, we consider in second transportation pr...
