Confidentiality Advisory Group (CAG) risk stratification application template
Risk stratification within the NHS refers to a process of applying algorithms and using tools to analyse data from multiple sources to identify high-risk patients who are likely to benefit from proactive care from their GP.
Risk stratification is done at Integrated Care Board (ICB) level with the support of suppliers of risk stratification services. These services use risk stratification tools to analyse the data to identify patients at risk, before returning their details to their GP for appropriate follow up.
Each ICB planning to undertake risk stratification will need to submit its own application to the Confidentiality Advisory Group (CAG). CAG will review each application and, if supportive, will advise the Secretary of State to set aside the duty of confidentiality for that instance.
NHS England and system representatives have co-produced this template for ICBs to use for their CAG risk stratification applications.
