How it works.
GP2GP starts when a practice accepts a patient onto its list of patients for primary health care and ends when the Electronic Health Record (EHR) is transferred from the previous practice into the new GP's clinical system.
Once the patient is accepted and his/her identity has been matched using the Personal Demographic Service (PDS) a message is sent to the previous practice requesting a copy of the patient's EHR (but only if the patient's former practice is also GP2GP-enabled).
The previous practice locates the patient and sends an acknowledgement stating whether or not it is able to provide the EHR extract.
If it is able to do so, then the EHR extract message is generated from the patient health record held on the GP clinical system and subsequently sent to the new practice for integration into its own GP clinical system.
