Project descriptor: Looking at the big picture across emergency stroke patients in England and Wales, the outcomes after stroke depend on the patient details, the stroke pathway and timings, and treatment decisions.
However, the data only reveals trends rather than the underlying causes of good outcomes. For example, did a patient have a good outcome because of treatment, or would they also have done so without treatment? Being able to fully answer why certain results happen will improve the trust of patients and clinicians in the conclusions drawn from big data and applied to simulations of the stroke pathway.
In response, we are trialling an approach that emphasises the “why” from the start. We start with no assumptions about links in the stroke data. Then causal discovery methods can uncover the links and so find which factors drive good outcomes.
This project is designed to test whether causal discovery methods can give trustworthy results for tabular medical data such as the stroke data. The intern will generate new data with known links between attributes, apply existing causal discovery methods, and check the accuracy of the inferred structures. We will visualise the results for non- technical audiences using network graphs.
Learning outcomes and training: Through this project, the student will learn how to work methodically by testing different scenarios in a structured way and keeping clear records of their results. They’ll also develop the ability to create clear, accessible graphs that communicate findings effectively to both clinicians and the general public.
Desirable background knowledge/skillsets: All applicants are encouraged to apply, regardless of prior experience, and there are no essential technical requirements or background knowledge required for this opportunity. However, having an academic background with some quantitative elements can be helpful. Any coding experience, such as using R or Python, may also be useful, but it is not expected that applicants will have experience in causal discovery methods or network graphs.
The UK has an urgent need for new health data scientists – it’s a rapidly expanding field with the recognised potential to transform the future of health and care for all. Therefore, we are seeking applicants with an enthusiasm to expand their knowledge and skillsets in this area of research and gain hands on experience tackling real-world biomedical and health care research challenges.
