Practical Experience in Modelling Health Care

Les Vertesi

Associate Director of Research

Fraser Health Authority

Shared Appointment with Simon Fraser University

Surrey, BC

Abstract

Health care is a complex world that poses serious problems for modeling. Simple models are not realistic, but models that try to mimic that complexity are difficult and time-consuming to build and perhaps even worse, are difficult for managers to use. As both a hospital manager and a modeler at the same time, the speaker has had to use the very models he has built and has thereby learned a practical approach to what is a universal modeling problem. Using examples of previous models designed to explore hospital and emergency department congestion, he will explain how a careful choice of the question can reduce model complexity, increase validity, and speed up the rate at which the model can respond to management questions.
