Hi there, I am working on modeling overcapacity surge policies in hospitals. I am trying to model a policy whereby a certain overcapacity/surge ward would only be used when the census of a location reached a certain threshold set by me. For example, a hospital has 50 beds. I would like to open up an additional 10 bed surge unit when the census of the hospital reached 45 beds. I suspect the way to do this might be using custom code to check the census of an area... but how could I accomplish making the surge beds only available once the census reaches the number I specify? Any ideas?
