What is CRIS?

The Clinical Record Interactive Search (CRIS) system allows researchers to analyse de-identified data from NHS electronic patient records. CRIS is also a valuable tool for service evaluation and clinical audit.

CRIS uses a computer program to remove or mask any information from an electronic medical record that might identify the person. (This includes data such as names, surnames, telephone numbers, addresses and NHS numbers). This creates ‘de-identified data’. This de-identified data then goes into a database that researchers can use.

CRIS was created by a group of innovative specialist mental health NHS Trusts, working together to speed up research into dementia and mental health.

How can CRIS help research?

Electronic records - particularly the free text notes - record a large amount of information, . This can help organisations better understand how care is being delivered, the causes of disease, and the effectiveness of interventions and medications. 

CRIS gives each patient record a unique ID in the database. This ID does not allow CRIS users to identify patients. However, where patients have given appropriate consent, authorised personnel can use the ID to contact patients who have been identified as potential recruits to an ethics-approved research project.

How do I access CRIS for my research?

Each NHS organisation using CRIS has a strict process to control who can access the database.

You must register and provide evidence of your employment contract. You must also have completed required training. An oversight committee will need to approve your project application.
