TLDR
A simulation queueing theory model with three input streams consisting of Emergency, Direct Elective and Direct Transfers is designed to examine the question of how bed counts impact access to acute care services in BC's hospitals and an optimization algorithm is developed to determine optimal bed allocations among hospital segments.Abstract:
In Canada, acute care refers to the in-hospital treatment of a disease during its initial phases (typically measured in days). Determining how bed availability impacts patient access to care is of great interest to the British Columbia (BC) Ministry of Health Services and to the health service delivery industry worldwide. In this article we discuss a simulation queueing theory model with three input streams consisting of Emergency, Direct Elective and Direct Transfers, designed to examine the question of how bed counts impact access to acute care services inBC's hospitals. We further develop an optimization algorithm to determine optimal bed allocations among hospital segments in order to minimize average patient wait time. The algorithm is demonstrated on an exemplar hospital.read more

Improving hospital bed utilisation through simulation and optimisation: with application to a 40% increase in patient volume in a Norwegian General Hospital.
TL;DR: A generic discrete event simulation model of patient flow through the wards of a hospital provides a powerful tool for optimising hospital bed utilisation and shows an important reduction in crowding bed usage.

Integrated Scheduling and Capacity Planning with Considerations for Patients' Length-of-Stays.
TL;DR: This work introduces the first dynamic multi-day scheduling model that integrates information about capacity usage at more than one location in a hospital and analyzes the firstynamic model that accounts for patients' length-of-stay and downstream census in scheduling decisions.

Intelligent Analysis of Acute Bed Overflow in a Tertiary Hospital in Singapore
TL;DR: With this insight, the hospital administration can be better equipped to devise strategies to reduce bed overflow and therefore improve patient care, and Computational results show the viability of these intelligent data analysis techniques for understanding and managing the bed overflow problem.

A simulation model for capacity planning in community care
TL;DR: This paper provides a simulation that helps determine the necessary downstream capacity in LTC in order to maintain smooth patient flow out of the hospitals in the region while still maintaining wait times within a target for those accessing LTC directly from the community.

Simulation of Nonhomogeneous Poisson Processes by Thinning
TL;DR: In this article, a simple and relatively efficient method for simulating one-dimensional and two-dimensional nonhomogeneous Poisson processes is presented, which is applicable for any rate function and is based on controlled deletion of points in a Poisson process whose rate function dominates the given rate function.

TL;DR: Simulation modelling is a powerful method for modelling both small and large populations to inform policy makers in the provision of health care and although the number of modelling papers has grown substantially over recent years, further research is required to assess the value of modelling.

Economic And Demographic Trends Signal An Impending Physician Shortage
TL;DR: A new model for workforce planning based on assessments of the macrotrends that underlie the supply and use of physician services predicts that the United States soon will have a shortage of physicians and that if the pace of medical education remains unchanged the shortage will become more severe.
