Concept of Operations for a Regional Telemedicine Hub to Improve Medical Emergency Response
Hui Wang, Christian Sandrock, Wei Xiong, Nathaniel Hupert, Christian Sandrock, Javeed Siddiqui and Aaron Bair
In this paper, we describe a simulation study used to examine the operation of a regional telemedi-cine hub during the acute phases of hospital patient management in a hypothetical earthquake scenario. We explore the im-pact of using telemedicine to provide emergency specialty care to expand surge capacities at both local and regional levels. Read more >> |

Utilization of Discrete Event Simulation in the Prospective Determination of Optimal Cardiovascular Lab Processes
John Pirolo, Abhijit Ray, Matt Gadzinski, Mario Manese, Brannon Garvert, George Scoville, Howard Walpole, Bob Amland, Rebecca Boos, Ian Mamminga, Joan Brown and Kipp Donlon
The clinical character of cardiovascular disease creates challenges in optimizing cardiovascular catheterization lab (CVL) throughput. A current state model was developed, pertinent data was collected for the patient group and validation of the model was performed. Analysis of simulation results determined the most efficient CVL schedule and re-source allocation to improve throughput and resource utilization. The study provides objective guidance to the optimal process modification and allows comparison of the relative differences in cost between the several redesign options. Read more >> |

Improving Patient Flow in a Hospital Emergency Department
D. J. Medeiros, Eric Swenson and Christopher DeFlitch
Hospital emergency departments in the US are facing increasing challenges due to growth in patient demand for their services, and inability to increase capacity to match demand. We report on a new approach to patient flow in emergency departments, and a simulation model of the approach. Initial results from the model show that the approach is feasible, and a pilot study demonstrates substantial improvements in patient care. Read more >> |
Optimizing Staffing Schedule in Light of Patient Satisfaction for the Whole Outpatient Hospital Ward
Soemon Takakuwa and Athula Wijewickrama
The waiting time for patients in outpatient departments of hospitals is a problem throughout the world. In this context, a discrete-event-simulation model was developed to examine congestions and doctor schedules in all departments of an outpatient hospital ward of the Nagoya University hospital.

Reducing Emergency Department Overcrowding – Five Patient Buffer Concepts in Comparison
Erik M. W. Kolb, Jordan Peck, Sebastian Schoening and Taesik Lee
Emergency Department (ED) overcrowding is a common medical care issue in the United States and other developed nations. One major cause of ED crowding are holding patients waiting in the Emergency Room (ER) for inpatient unit admission where they block critical ED resources. With input data from a hospital in Massachusetts/USA, we tested five patient buffer concepts which aim at relieving pressure of the ER. Read more >> |
Using Simulation in the Implementation of an Outpatient Procedure Center
Todd R. Huschka, Brian T. Denton, Bradly J Narr, M.D. and Adam C. Thompson
Creation of an Outpatient Procedure Center (OPC) is a complicated endeavor, requiring a detailed understanding of the resources available and the procedures to be performed. Miscalculation of resource allocation or patient flow through the area can result in the waste of expensive resources, patient dissatisfaction, and health care provider inefficiency. The use of discrete event simulation can assist in the design. Read more >> |
Outpatient Appointment Scheduling in a Multi Facility System
Athula Wijewickrama and Soemon Takakuwa
This study evaluates appointment systems used in hospitals by incorporating appointment rules and patient characteristics. Using an experiment unit at an internal medicine department of a large outpatient ward in Nagoya university hospital, a number of prevailing assumptions were relaxed, and twenty-five appointment systems were developed combining five appointment rules with five patient sequences. These appointment systems were evaluated. Read more >> |
Improving Hospital Evacuation Planning Using Simulation
Kevin Taaffe, Matt Johnson and Desiree Steinmann
This research describes the development of a simulation model and initial analysis to assess the effectiveness of a hospital evacuation plan given different scenarios and resources. Read more >> |
The Use of Simulation to Determine Maximum Capacity in the Surgical Suite Operating Room
Sarah M. Ballard and Michael E. Kuhl
We present a general methodology for determining the maximum capacity within a surgical suite through the use of a discrete-event simulation model. Read more >> |
Simulation Analysis of an Outpatient Department of Internal Medicine in a University Hospital
Athula Wijewickrama and Soemon Takakuwa
Waiting time in outpatient departments is a problem throughout the world. One consistent feature of patient dissatisfaction has been expressed with the length of waiting time. Read more >> |
Assessing the Viability of an Open Access Policy in an Outpatient Clinic: A Discrete-event and Continuous Simulation Modeling Approach
Ronald E. Giachetti, Edwin A. Centeno, Martha A. Centeno and Ramakrishnan SundaramThis paper presents the preliminary results of an ongoing research project investigating the patient appointment scheduling for an outpatient clinic. The outpatient clinic was experiencing three problems of long patient throughput times, a large backlog of appointments, and a high noshow rate. Read more >> |
