Abstract

How does the COVID-19 pandemic influence the congestion probability of the ICU? In this paper two models are given to capture the interaction and effect of COVID to non-COVID patients at the ICU and its possible effect on postponed surgeries for a single hospital. Particularly a coordinate convex interdependence is allowed. So-called product form expressions are derived that can be used to compute B^t, the patient dependent congestion probabilities. It enables, as illustrated with real data, to calculate the congestion probabilities for the different patient types.
