Due to expensive procurement cost and high operating cost, Magnetic Resonance Imaging (MRI) is usually one of bottleneck resources in hospitals. As MRI is shared by multi-types of patients with different requirements of examinations, setup time is needed to change coil between different patient types. Therefore, the same type patients are arranged in a sequential order to reduce setup time. This paper...
The paper set up the Causal Relationship model of medical service pricing to analyze dynamic equilibrium between various factors based on analyzing the pricing process. Furthermore, this paper established the mathematic model of medical service pricing based on government and hospitals co-decision. Finally, the paper built the simulation model of medical service pricing based on the theory of System...
This paper presents a simulation of an ambulatory processes using timed Petri net (TPN). The simulation considers the flow of patients in the biggest Brazilian cardiology hospital. The TPN is used as a decision support system (DSS) in order to improve the processes, to reduce the waiting time of the patients in the ambulatory and in this way to assure a high quality service to the patients. Simulations...
Emergency Departments (ED) is the center of the hospital management's efforts. It constitutes a complex system with limited resources and random demands. The goal of this paper is to optimize the number of the human and material resources. We focus particularly on medical staff (physicians and nurses) and beds in emergency department. We propose a mixed integer linear programming (MILP) that minimizes...
The purchasing function is the strongest link in the hospital supply chain. The stakes which are related to it are often complex and difficult to define. Public institutions and hospitals are all invited to master these link operations, with a particular focus on the hospital-supplier relationship. One of the most crucial is the selection of the right supplier, which is based on both qualitative and...
This paper deals with the home health care services. The home health care services are defined as a set of medical, paramedical and social services delivered to patients in their domicile rather than in hospital. In this paper, a new Mixed Integer Linear Programming (MILP) model is proposed to make a planning for a home health care problem. The model is optimizing routes and rosters for the health...
We have been studying the spread of meticillin (multi) resistant Staphylococcus Aureus (MRSA). In the course of these studies, we investigated information about all patient visits within Stockholm County during the outbreak period, with registry over all diagnosed MRSA cases. As part of this project, we developed methods for analyzing the contact network of persons who had visited the same care facility,...
In the last years, the Italian healthcare system is facing significant challenges, that underline the serious need for radical changes. Indeed, there is broad evidence that, even though a huge amount of money is invested in healthcare services every year, the patients often do not get the care they need. Thus, reforming the healthcare delivery system in Italy is mandatory, to ensure high care quality...
Atrial regions hosting dominant frequency (DF) may represent potential drivers of persistent atrial fibrillation (persAF). Previous work showed that DF can exhibit cyclic behaviour. This study aims to better understand the spatiotemporal behaviours of persAF over longer time periods. 10 patients undergoing persAF ablation targeted at DF were included. Left atrial (LA) non-contact virtual electrograms...
A brain-computer interface (BCI) character input experiment focusing on participants’ BCI intelligibility was performed. In theory, a BCI can be operated by anyone if cognitive activity is possible. However, individual differences clearly occur in practice. Therefore, we supposed that this difference was related to BCI intelligibility. In a previous study, BCI experts and BCI novice users were compared...
This paper studies the medical resources order and distribution scheduling problem with stochastic demand. A chance-constrained programming model is proposed based on time-space network with the objective of minimizing the hospital's total operating costs. Generic algorithm is employed to solve the optimization model. The numerical test results show the good performance of the proposed method.
This paper discusses the layout of different functional departments in the hospital. By relocating the departments overall, we aim to minimize the average walking time for the outpatients from the registry to their consulting departments, thus enhancing the hospital's service efficiency. Actually, this is typically a quadratic assignment problem (QAP). Since the hospital's departments tend to vary...
The big data in Accident and Emergency services in hospitals worth being analyzed to provide clinical decision support to clinicians and medical information to patients. System Dynamics modelling is a technique used for modelling complex behaviors of organizational and social systems. In this study, a system dynamics approach is used to model the patient flow in Accident and Emergency in Hong Kong...
Nurse scheduling problem (NSP) is a complex optimization problem of determining schedule for nurses by considering some constraints such as legal regulations, nurses' preferences, hospital policies and requirements. It is a difficult and time consuming task to deal with large problems with many constraints. In addition to this, in real world application, a person who prepared this schedule (e.g. head...
Despite heated debate about the pros and cons of online physician ratings, very little systematic work examines the correlation between physicians' online ratings and their actual medical performance. Using patients' ratings of physicians at Rate MDs.com and the Florida Hospital Discharge data, we investigate whether online ratings reflect physicians' medical performance by means of a two-stage model...
While several studies have been conducted relating to the acceptability and use of Smart National Identity Card (SNIC), research in determining factors that influence the citizens' acceptance and use of health information application in (SNIC) has not yet been conducted. This paper presents a new paradigm of individual level technology acceptance and use framework known as I-P (Individual-Privacy)...
Hospitals use very costly medical equipment like scanners, RMI, endoscopy equipment or operating rooms. In this paper, we propose a mixed integer model to schedule patients on different hospital resources they can need during their stay in a hospital. We study the case of multiple types of resources and for each type the existence of several parallel units. The objective is to minimize the sum of...
Unmet clinical needs remain the primary driving force for innovations in medical devices. While appropriate mechanisms to protect these innovative outcomes are essential, the performance of clinical trials to ensure safety is also mandated before the invention is ready for public use. Literature explaining the relationship between patenting activities and clinical trials of medical devices is scarce...
The present work reports the results of a case study realized by processing and interpreting the data obtained in a full-scale experiment performed at the City Hospital in Turceni, Gorj County (Romania). As its title itself shows, the paper presents a numerical simulation of the airflow pattern in a hospital room whether or not a portable air conditioner is in use within it. The main purpose of the...
This paper presents a modeling methodology for clinical guidelines used in hospitals. The clinical guidelines are assumed to be given in a graphical form in a structure obtained by combining few elements. It is shown how the clinical guidelines represented with this syntax can be automatically converted into a mathematical model represented as Petri nets. The main advantage of the new model is the...
