This paper describes the simulation modeling for planning for the efficient transportation of patients following a disaster. Research was performed in an effort to predict the consequences of conceivable scenarios. Discrete-event simulation modeling provided an effective supplement to regular drill procedures when training emergency medical services personnel.Initial performance of the redesigned...
As Web services composition arouses a growing interest, most research works address implementation and execution issues. As a consequence, many composition languages (BPEL, XLANG, WSFL, WSCI, to name a few of them) have been proposed in the past few years. However, a weakness of these languages is that they are difficult to use in early stages of development, such as specification. UML-S is an extension...
The privacy/security regulation of HIPAA has addressed many of the rights and obligations of both the patient and the health information system. Emergency treatment, however, still presents problems as we do not have an exact definition to apply. By employing cryptographic techniques, we provide a novel model which can confirm several essentials in HIPAA. In particular, we have discussed how the new...
This study aims to add tele-ultrasound techniques and emergency physician support to improve the quality of pre-hospital medical emergency services. On the other hand, a diagnostically useful FAST scan is dependent on the skill level of the EMTs using the portable ultrasound unit. However, providing adequate tools is still a prerequisite to the successful execution of a job. In the future, an improved...
This paper proposes a u-Healthcare system that can perceive emergency situations in chronic hypertension patients and initiate emergency action. The proposed system considers patient mobility and integrates a medical recommendations knowledge base and communication protocols between system agents in an RFID and Cell phone architecture. A comparison and analysis of the proposed system and the operational...
A frequently chosen time window in defining readmission is 28 days after discharge. Yet in the literature, shorter and longer periods such as 14 days or 90-180 days have also been suggested. In this paper, we develop a modeling approach that systematically tackles the issue surrounding the appropriate choice of a time window as a definition of readmission. The approach is based on the intuitive idea...
Telemedicine is a general term which is used to define various aspects of health care at a distance. Also, telemedicine can be defined as the use of telecommunication technologies to provide medical services. The key aspect of telemedicine is the use of electronic signals to transfer information from one place to another. Since the invention of the telephone, medical practitioners have employed electronic...
Effective hospital capacity planning can not only significantly enhance the capability and effectiveness of the treatment provided to patients during a bioterrorist attack but can also provide critical information. While a lot of work has been done to model hospital capacity estimates for natural disasters the same cannot be said for manmade biological disasters like anthrax or smallpox. In this paper,...
Simulation of existing systems can reinforce a Subject Matter Expert's gut feelings. However, it is more difficult to develop intuition for proposed systems, particularly when considering the consolidation of multiple systems. This paper discusses the use of simulation to determine the operational ramifications of combining six Emergency Departments into one of the largest in the country. Each of...
During the last 50 years natural and social disasters have increased 250 %, affecting at least 800 million people. The causes of these disasters are various and most of them are not predictable. A successful strategy is a well planned medical response. The use of Field Hospitals 'FH' specialized for the disasters and planned to guarantee high technical and medical standards is a fundamental component...
Emergency department becomes a useful way to the access to hospital and it is a subject of study for many researchers. The research developed in this paper aims to improve the performance of the emergency department (ED) of Sfax Hospital by simulation model. So, two implementation models are proposed, dynamic and static model. Different indicators of performance are used.
Health emergencies occur frequently and need to be handled fast and effectively. The classical procedure for handling a health emergency is to reach the closest hospital and wait to be directed to an appropriate medical unit afterwards. However, depending on the patient's situation, other factors may be relevant in deciding which hospital to choose.
Emergency department overcrowding has become a major issue over the past decade. This research investigates emergency department overcrowding resulting ambulance divert. Patient flow models of the emergency department were developed using Petri Nets. The objective of these models is two-fold, to analyze patient flow in the emergency department and to assist in determining the minimum sequence of events...
The use of biological agents as weapons can cause disease and deaths in sufficient numbers that can greatly impact a city or region. Consequently, concerns about the preparedness and efficiency of healthcare systems for bioterrorism events have increased dramatically among hospital managements. This paper presents an innovative and sophisticated computer simulation model of the emergency room (ER)...
As part of a larger project examining the effect of performance targets on UK hospitals, we present a simulation of an Accident and Emergency (A&E) Department. Performance targets are an important part of the National Health Service (NHS) performance assessment regime in the UK. Pressures on A&Es force the medical staff to take actions meeting these targets with limited resources. We used...
