This project was supported by two The Health Foundation grants (1st, 2nd) and was led by the Bristol, North Somerset and South Gloucestershire Clinical Commissioning Group (CCG).

The project involved building a computer simulation tool that is sufficiently flexible to accommodate a number of interconnected services along a given patient pathway.

The resulting tool, PathSimR, is an open source R-based tool designed to model patient flow and capacity along clinical pathways. It is an open-source software tool and freely available through github.

So far we have used PathSimR to support the reconfiguration of acute stroke services in the Bristol Health System (paper under review, EURO2022 abstract here) and to explore financially sustainable initiatives to address out-of-area placements in psychiatric ICUs. We also used the tool to support the operation of mass vaccination centres - see separate project page.

The main PathSimR paper has been published in the Journal of Simulation.
