ECRIC asked us to create a tool that enables health professionals to analyse patterns in the treatment of cancer patients. We needed to find a way of visualising how full datasets of patients are transferred between hospitals for different types of treatment. To do this we used a graph representation where patients with the same set of hospital treatments are grouped together as cohorts, and are linked to the hospitals providing treatment. This enables users to see both typical treatment pathways, and also outliers.
To ask more specific questions of the data, we developed an open ended filtering system that can pick out cohorts of patients across a wide variety of criteria.
The software is being developed both as a configurable tool for internal use, and also as a visualisation interface for use by other health professionals, researchers and health organisations.
