Abstract

Infection prevention and control (IPC) decisions play a critical role in mitigating the spread of infectious diseases in healthcare settings. These include cancelling visitor appointments, isolating infected patients and quarantining bays. While these measures are introduced to reduce the spread of infections, some put restrictions on patient movement and thus worsen patient flow, creating organisational and medical issues. IPC nurses and hospital bed managers are therefore faced with hard decisions about how to reduce the risk of infections spreading without unduly impacting patient flow.

We developed a Discrete Event Simulation model to determine the consequences of an IPC policy in terms of a set of metrics which captures the impact on the spread of infection and patient flow. We also developed a Continuous Time Markov Chain Model that was used to validate the simulation model and to give exact results for simple scenarios.

In this presentation, I will focus on one use case of our models and describe methods we have established to support decision making; for example providing general rules of thumb about when policies are preferable. I will describe how they might be used in practice, including the benefits and drawbacks of each.

This presentation is an exploration of how models can be used to aid healthcare workers with complex decisions, in this case relating to trade-offs between the potential impact of IPC decisions on infection spread and patient flow.
