CogStack

CogStack is a healthcare application framework that allows you to handle, analyse and draw insights from information from unstructured free-form clinical data sources e.g. Electronic Health Records where majority of the expressive clinical content is locked-up in multiple formats of unstructured data (i.e. binary word docs, PDFs, images, text). Features include Natural Language Processing (NLP), Full Search, Alerting, Cohort Selection, Population Health Dashboards and Clinical Research.

Testimonials

At King’s, a brilliant team led by Dr James Teo and Professor Richard Dobson have built a natural language processing tool called Cogstack. The Cogstack AI can perform manual coding and data collection tasks in a tenth of the time that it takes a human analyst. Technologies like these have potential to save millions in the cost of coding and analysing data.

Secretary of State for Health and Social Care
The team at King’s College Hospital NHS Foundation Trust and the South London and Maudsley Hospital tested CogStack for clinical coding in a fracture outpatient clinic setting to identify under-coding and was able to triple the depth of coding within a month (from ~10% of cases to 30% of cases having procedures recorded accurately). This translates to £1,260,000 of financial activity per annum even without the efficiency gains

Health data is key in getting it right for patients, but we’re not so good at the IT. CRIS, CogStack and automated systems support data collection and analysis can provide powerful evidence and very important for outcome measurement.

Have a look at CogStack - big opportunities for these use cases at East Kent Hospitals once the electronic health record is in place.

Kullu Cecil and I are involved in work using historical data and current data to predict severe depression. Uses CogStack from King's College London and AI expertise from Liverpool Uni. Some early promising results. Looking for approvals to trial in clinical setting.
