For hospitals, the variability on demand (number of daily urgent admissions) and the variability in the Length of Stay (LoS) (bed occupancy) may affect the quality of service provided to patients and the effectiveness of the overall service. This paper studies the LoS of 238 patients who performed hip surgery in the orthopedic service of a Portuguese hospital in 2014. It uses variables available in...
Hospital Information Systems (HIS) has been considered by health care providers as the answer to provide a quality service and help their employees to work effectively and efficiently. The purpose of this study was to identify the factors that influence users' acceptance level of HIS in a private multi-specialty hospital in Indonesia as it was expected to give a proper guideline for the management...
The management of pre hospital logistics is addressed by several researchers. That is due to the big impact that has healthcare around the city development. Thus, optimizing emergency traffic helps to smart cities growth. This paper includes coverage problems existing in literature and addresses the ambulance allocation to cover sectors in Casablanca region of Morocco and minimize the lateness of...
In the hospital sector, simply looking for suppliers offering the lowest prices is not “efficient sourcing” any more. They undertake a thorough reflection on the procurement strategy to follow with various suppliers, of medicines and medical equipments. There is often a tussle between choosing a right sourcing strategy which says, whether the hospital should go for single or multiple sourcing. In...
It has been widely recognized that decision-making is a crucial part of hospital management which goes through a process of medical behavior. Even though data mining and knowledge discovery techniques have been used to clinical medicine frequently, little research has been conducted on hospital decision-making especially hospital-cost analysis on treatment therapies among inpatients which is considered...
As any technology, medical equipment provides benefits to patients, but they also present significant risks that can affect and threaten patient safety. In healthcare organizations, clinical engineering departments play a big role in maintaining the safety and reliability of medical equipment. In order to mitigate failures of such equipment and control risks, a proper Medical Equipment Management...
The aim of this study is to make simulations with Matlab/Simulink to be used in the production phase of the autoclave in the sterilization unit. Sterilization unit is very important in terms of hospital employees and patients for protecting from infections and accidents. The study examined autoclave equipments that are fabricated based on the EN standards, then mathematical calculations were performed...
In this paper we present the plan, motivation, background, and the design of an agent-based simulation framework describing the spread of Hospital-Associated Infections (HAIs). We are developing a general simulation environment that is able to model wide range of pathogen transmission scenarios in hospital environment. The elements of the simulation include among others: admission and discharge patients,...
In this paper we present a model of single-hop type wireless sensor network with random access and oneway transmission. In the paper, we analyze the WSN single-hop network using one single radio frequency, such that all nodes are divided into several groups depending on the average time between the transmissions. We replaced deterministic number of nodes in groups by random variables. We apply the...
In this paper, we try to improve health care services by treating the variation among several issues related to the health field, particularly the Home Health Care Problem (HHCP). In fact, Home Health Care Service (HHCS) is known as a care mode allowing patients who suffer from complex and evolving diseases to benefit at home from medical and paramedical coordinated care that can be only provided...
This paper considers the operation scheduling and planning of elective patients in the Orthopedic Department of the “Lozano Blesa” Hospital in Zaragoza. We assume an ordered list of patients that should be planned for surgery in two available rooms, each room being possible to be used for a specific duration per day. Based on the average durations of surgeries that have been computed by considering...
Diagnostic facility is one of the most important critical resources in the hospital. Patient scheduling plays an important role in managing these facilities, especially when they are shared between regular and emergency patients. Due to the non-stationary emergency arrival and waiting time targets of emergency patients, it is challenging for hospital managers to make appointment scheduling decision...
A patient journey in the hospital may include many departments or units. Making safe and smooth transitions within the hospital is of significant importance. This paper introduces a Markov chain model to study patient transitions between emergency department, intensive or critical care unit, and hospital ward. An iteration method is presented to evaluate the performance of transition process. It is...
Up to now, with the increasing of the elderly population, more and more patients are suffering from hemiplegia. The needs for hemiplegic rehabilitation is increasing quickly. As traditional rehabilitation, each patient must be treated by therapist, one by one. However, because of the different levels of therapists, the rehabilitation cannot be performed as the as the same. Normally, the rehabilitation...
We conducted a field study in a nephrology practice that performs multiple functions in a variety of distributed settings. The task of physician scheduling was done manually on paper by a single scheduler. Our study revealed challenges persistently encountered while using a plethora of fragmented, transient paper artifacts. Any changes made to existing schedules often impact other physicians' schedules,...
We have selected 12 pulmonary Tuberculosis patients from Peri-urban zones of Lima city where all of them are still using public transport to visit hospitals and health centers. Patients were involved in the testing of a prototype of teleconsult which was based in phone calls and text messages giving as result that the number of hours/month of mobility of TB patient in Lima city using buses and minibuses...
In the multi-floor hospital architecture, safety for in-patients is empowered if the hospital staff knows their location inside the building. Received signal strength (RSS) based method is commonly utilized in 2D geolocation but not equally efficient in 3D environment, since the signal suffers significant loss when going through ceilings between floors. This paper develops a barometer-assisted approach...
The existence of inventory for a company is essential and unavoidable, but its presence is often regarded as a waste. Therefore, inventory control is an important thing to do in order to optimally fulfilled product demand. Pharmaceutical unit is an installation support for the Hospital to provide drugs. Medicine is one of perishable products. Recently at department of pharmaceutical logistic in a...
A nosocomial infection is caused by microorganisms acquired in healthcare environments and it causes serious health problems to patients. Controlling the propagation of this infection is a topic of great interest in the health field. Our work focuses on propagation of nosocomial infection in emergency departments from the point of view of the physical contact among the people involved in the care...
This paper introduces a new optimal control model to describe and control the dynamics of infectious diseases. In the present model, the average time to isolation (i.e. hospitalization) of infectious population is the main time-dependent parameter that defines the spread of infection. All the preventive measures aim to decrease the average time to isolation under given constraints. The model suggested...
