The Summary Care Record is a summary of basic health information about you, that healthcare professionals can access, to inform the care that they provide. They will ask your permission each time before they do this, unless this isn't possible, e.g. if you are unconsious. The information on the Summary Care Record will include basic details including allergies and medication.
It is possible to opt out of this service. However, there will be important benefits to the Summary Care Record, so it's important to find out more if you are thinking of opting out.
