The Electronic Prescription Service (EPS) uses a request or response messaging pattern to download nominated prescriptions from the NHS Spine. Functional requirements due to technical constraints within the original Spine architecture (circa 2005) prevented the automated polling of nominated prescriptions during normal working hours.
With the current Spine architecture such constraints are no longer required. From July 2016, dispensing systems can request prescriptions at any time, including scheduled polling for nominated prescriptions, subject to two constraints;
- Polling must not be more frequent than every 2 minutes
- When the response returns no available prescriptions then the system must wait at least 2 minutes before polling again.
Dispensing system suppliers who wish to implement polling functionality can do so without the need for additional NHS Digital assurance.
A Supplier Change Note (SCN) must be submitted so we aware of the change. Once implemented, the schedule configured for polling can be changed without need to notify us.
