More Gme with paGent
KConnect at RJL? • Live paGent E.H.R. ‘reading’ (overview from text analysis)
• Further medical search across many sources from a paGent E.H.R. view or accessed independently
• Search either before, during or aqer paGent consultaGon
• As a search tool for supporGng medical informaGon -‐ clinical trials, medical studies, treatments, guidelines (and later possibly across anonymised paGent EHRs)
• Facilitate the care process – the search engine knowledge base can give support in finding the best diagnosis and treatment
KConnect – How does it work? Based on
RJL permissions Ethics Patient privacy/security System & data access permissions Collaborations!
KConnect – via the PaGent EHR
KConnect – Results Page
Use Cases Jönköping v KCL, London
• Live analysis of paGent E.H.R.s and further invesGgaGon into medical literature, guidelines etc.
• To provide helpful informaGon in decision-‐making processes
• Future: Symptoms-‐Diagnosis (addiGons to KB) • Future: Search across anonymised EHRs
Jönköping
King’s College, London & South Maudsley Hospital (NHS)
• Analysis across pseudo-‐anonymised paGent E.H.R.s • ExtracGon of paGent types, disease, symptoms etc to databases • To predict Adverse Drug ReacGons (use of KB and new doctor RDF notaGon) • To evaluate risk of suicide in mental hospital paGents (pa]erns)
