Why is population calculated differently for hospital services and GP prescribing?
For hospital services the population is based on the NHS Board of Residence, however, for GP prescribing the population base is NHS Board of Management. For GP prescribing the activity measure is the volume of prescribing based on GP practices irrespective of the home address of the patient. Population is based on the number of patients on the lists of GPs managed by each NHS Board, rather than simply the NHS Board of residence.
