CRIS is an internationally unique data resource comprising de-identified full electronic mental health records from the South London and Maudsley NHS Foundation Trust (over 500,000 patients) with extensive enhancement through multiple data linkages and natural language processing (‘text-mining’) algorithms. CRIS has been used extensively for research to improve the understanding of mental health conditions and mental healthcare services, and has supported over 250 peer-reviewed publications.
Rob Stewart’s work on CRIS has focused particularly on the physical health inequalities faced by people with mental disorders, as well as longstanding interests in the physical health impact of dementia and its implications for safer prescribing. He directs several programmes of work to improve the quantity and quality of data from routine electronic health records through natural language processing.
