Project #58:
Carehomes Short Data Report


This short data report compared different strategies for identifying care home residents in electronic health records in England. Historically, GPs do not enter whether or not a person is living in a care home in their medical record. There is also no central registry of care home residents. Therefore, when we want to study people in care homes using electronic health records from GP surgeries, we need to rely on other methods to identify these people.

In this report we compared using medical codes, an address linkage, and household information to identify care home residents. We describe how these methods are implemented in OpenSAFELY, and compared the overlap between them.
