Overview

Aims
The Clinical Record Interactive Search (CRIS) system is a database and computer system that links administrative records of individuals who have accessed the South London and Maudsley (SLaM) NHS Foundation Trust, the largest provider of secondary mental healthcare in Europe, with other administrative data.

This linkage generates a cohort with rich data and enables researchers at the NIHR Maudsley Biomedical Research Centre (BRC) to derive and analyse these data. To facilitate this, the CRIS team have also set up a Natural Language Processing (NLP) Service to support the use of free text responses in electronic health records to research.
