Prescribing figures in this publication are based on information systems at NHS Prescription Services, part of the NHS Business Services Authority. The figures used are collected as an essential part of the process of reimbursing dispensers (mainly pharmacists and dispensing doctors) for medicines supplied. All prescriptions that are prescribed in England and dispensed in the community in the UK need to be submitted to NHS Prescription Services if the dispenser is to be reimbursed, so coverage should be complete. If a prescription was issued but not presented for dispensing or was not submitted to NHS Prescription Services by the dispenser, then it is not included in the data.
The prescription item is recorded in the month in which NHS Prescription Services received it. In the majority of cases prescriptions will be issued, dispensed and submitted to NHS Prescription Services in the same month. However, prescriptions can be presented for dispensing up to six months after issue, and the dispensing organisation may submit the prescription for payment late. Prescription data may be attributed to organisations that have since closed for three potential reasons:
- An issuing organisation may close after writing a prescription but before the prescription is dispensed
- NHS Prescription Services may receive the reimbursement claim late from an organisation
- A prescription pad from a closed organisation may still be in use by a prescriber previously at that organisation
NHS Prescription Services have internally audited their prescription processing accuracy to 99.7% over the period Jun 2018 – May 2019.
