Best Practice uses the 'Usual Doctor' field in the patient demographics as the patients assigned provider.
Where a 'Usual Doctor' is not selected, patients will be assigned to a particular provider based on which provider they were most frequently seen by in recent consultations. Providers that are inactive are excluded.
Patients will be assigned to the active provider who saw them for the highest number of consultations in the previous 18 months.
Where there is no consultation recorded in the previous 18 months, the patient will be assigned to the active provider who saw them most recently, up to 5 years ago.
Where there is no consultation recorded in the previous 5 years, no provider will be assigned.
