Technical requirements and standards
Technical requirements and standards
Pharmacy and prescribing system suppliers align with minimum requirements (e.g. EPS specifications) that set out what must, should, and can be done.
Suppliers also can innovate beyond what is specified based on user requests e.g. improving usability, and based upon user feedback to them. Community Pharmacy IT Group supports pharmacy systems (and systems within other health care settings) integrating with NHS IT and other IT that enables pharmacy teams to further optimize the care they can provide for their patients.
This webpage for pharmacy contractors and suppliers sets out some of those integrations and technical requirements that enable pharmacy systems to work with other IT.
The creation of Application Programming Interfaces (APIs) along with specifications and technical requirements can help provide system suppliers with a blueprint for inter-operating.
In some cases NHS Digital may be involved with being commissioned to develop APIs and make these available for system suppliers to make use of.
See the Apps webpage and its sections: Apps standards and Developer info.
Clinical referral information standard (PRSB)
PRSB continues to develop this standard that sets out how communicate electronic referrals e.g. from GPs to hospitals.
Read more at: PRSB’s Clinical Referral Info webpage.
Computable dose instructions standards
Core information standard (PRSB)
The core information standard defines a set of information that can potentially be shared with electronic health records systems – for sharing between systems in different sites and settings, among professionals and people using services.
It will be tested within some LHCR systems.
Read more at: PRSB’s Core Info standard webpage.
Community Pharmacy Contractual Framework (CPCF) IT requirements information may be added in future if these become available.
Community Pharmacy IT Group believes additional CPCF specifications are a key priority to help fulfil the ambition of CPCF.
Specifications or toolkit equivalents (ideally published at least 6-12 months before new services begin) should be a standard for all future services including CPCF ones. This would also help pharmacy IT suppliers to be better able to build standard interfaces for receipt of information and recording of information to central

Discharge Medicines Service (DMS) MYS API
From 15th February 2021, NHS Trusts were able to refer patients who would benefit from extra guidance around new prescribed medicines for provision of the DMS at their community pharmacy.
Summary data on each DMS provided will have to be provided to support the evaluation of the impact of the service, contract monitoring and post-payment verification.
In time, your pharmacy IT system may support collation of that data** or alternatively, the PSNC DMS worksheet (see the DMS webpage resources section) will also allow you to make clinical records for the service and collate the summary data for submission to the NHSBSA.
NHSBSA and NHSE&I supported by NHS Digital and PSNC, started work with pharmacy IT system suppliers in October 2020 to support the development of an Application Programming Interface (API) which will transfer the DMS summary data from pharmacy IT systems to the NHSBSA’s Manage Your Service portal, so the information does not need to be manually entered into MYS by contractors.
There is an NHSBSA objective to progress the specification work further during summer and autumn 2021, and for a ‘go-live date’ ideally by autumn 2021 dependent upon supplier developments. PSNC is continuing to push for NHSBSA and suppliers to progress this work at the earliest opportunity.
NHBSA have produced a DMS API spec and sent it out to pharmacy suppliers, and plan for additional work to also develop the API within the BSA.
NHSBSA has requested that suppliers advise NHSBSA as to when they are expected to put this on their roadmap. NHSBSA reported to PSNC (September 2021) that it is continuing to await supplier responses from all of the suppliers that were contacted.

Digital token future standards
Community Pharmacy IT Group (CP ITG)’s updated Views on the next generation of EPS had set out priority items for exploration including: “Enable paperless prescription processing (digital tokens developed and suitable guidance and standards in place) (EPS Phase 4 prescriptions and NHS Digital token specification  updated to specify digital token requirements).”
Some GP practice apps might display barcodes and IDs but may do so without those digital tokens having been formally approved by NHS Digital, given that the current Token specs outline paper requirements.
CP ITG is keen to hear views about Phase 4 digital tokens, and other prescribing / dispensing digital tokens. Contact email@example.com if you’d like to submit views about future token standards – e.g. for items which NHS Digital could consider adding to the future Digital token specifications. See also: psnc.org.uk/tokens.
Everyday Interactions (PHE)
Outlines public health impact ‘pathways’ to support pharmacy teams and others to record what they ‘do’ in their interactions with patients, what data can be collated and also the possible impacts from these interactions. These pathways could be of interest to pharmacy contractors and their system suppliers. The pathway templates include: Obesity, alcohol, dementia, and smoking.
A platform specification that defines a set of capabilities used across the healthcare process, in all jurisdictions, and in lots of different contexts.
See: FHIR standard
Allows patients’ electronic health records to be transferred directly, securely, and quickly between their old and new practices, when they change GP practices.
See: GP2GP service
GP Connect is an NHS Digital managed service that currently allows GP practices and certain other authorised clinical staff to share and view certain appointments information, electronic health records information and data between IT systems.
It uses standards that enable interoperability between different clinical systems (e.g. it can facilitate collaborative work of two sets of GP practice staff that use two different GP systems).

GP notifications from pharmacy systems (e.g. flu vaccination)
Direct notifications can be communicated between clinical IT systems (e.g. from pharmacy system to GP practice system) to improve patients’ experiences and care outcomes, and to bring other health-related benefits.
The Professional Record Standards Body (PRSB) has worked with NHS Digital, PSNC, clinicians from across primary care, and others to develop several standards for electronic transfer of information which could be sent from pharmacy systems to GP practice systems.
The use of Flu vaccination service PRSB-developed notification is currently being piloted by NHS Digital within Leeds and further information is set out below.
NHS Digital’s Digital medicine specification versions includes developed specifications to support communication of:
- Pharmacy immunisation administration (including flu vaccination)
- Pharmacy emergency medication supply
- Pharmacy New Medicine Service (NMS)
- Pharmacy medication review
- Pharmacy digital minor illness referral service
- Pharmacy appliance use review

Local Health and Care Records (LHCRs)
In the future, pharmacy system suppliers as well as other clinical system suppliers may be able to display information from LHCRs. Initially it is expected LHCRs will mainly be used in many sectors via online portal systems.
Integration standards: Community Pharmacy IT Group (CP ITG) have identified that there needs to be a standard approach for supplier integration with any LHCR system so that the same supplier can easily integrate with many of the LHCR systems if integrated with a single one of them. This feedback was passed to NHS Digital to help inform its standards work.

Medicine and Allergy/Intolerance Data Transfer (ISN)
NHSX commissioned NHS Digital to produce an Information Standard which puts in place definitions that could be used when a health professional sends or receives patient medication and allergy/intolerance information, by computer system, between care locations.
NHS Digital initially published the standard on 30th September 2021 and proposed an implementation period of 1st October 2021 to 31st March 2023.
CP ITG suppliers were notified about the standard and some related engagement opportunities which were to occur near the time of the standard’s initial publication.
Read more: Medicine and Allergy/Intolerance Data Transfer.
If you’d like to feed into the standard’s development for PSNC and CP ITG please contact firstname.lastname@example.org.

NHS online / Patient Facing Services
See: Patient Facing Services.
It becomes ever more critical that pharmacy teams get the most out of their patient medication record (PMR) systems and help to feed into the development of those by emailing their system suppliers and also sharing feedback to help further develop the wish list.
Following discussions at its meetings and feedback from pharmacy teams, the Community Pharmacy IT Group (CP ITG) published:
ODS (F) code
The contractor code is a pharmacy’s unique identifying code which appears at the top of the schedule of payments document that is received from the Pricing Authority each month. The code is officially known as the ODS code, and was previously called the OCS code, NACS code or F code.
See: ODS (F) code
Pharmacy information flows dataset (PRSB)
The PRBS website set out this dataset.
It also relates to the Digital Medicines specification published at HDN.
These datasets may be amended further.
Real-time exemption (RTEC)
Real Time Exemption Checking (RTEC) is a technical solution enabling the PMR system to automatically find out whether a patient has a known exemption that can auto-apply to their EPS prescription. If the PMR system confirms an exemption, the EPS prescription is auto-flagged as exempt so that the patient won’t need to make a written exemption status declaration. If the system cannot identify an exemption the pharmacy team and the patient will use the usual process.

SNOMED CT (clinical terms) is a clinical vocabulary readable by computers. SNOMED was an acronym for Systematized Nomenclature Of Medicines. SNOMED CT is largely considered as a brand name rather than an acronym.
It is used in electronic health records, SNOMED CT is the most comprehensive and precise terminology product in the world, with extensive adoption across the globe.
SNOMED CT gives clinical IT systems a single shared language, which makes exchanging information between systems easier, safer and more accurate. It contains all the clinical terms needed for the whole NHS, from procedures and symptoms through to clinical measurements, diagnoses and medications.
In England, all GP systems capture clinical terms using SNOMED CT. The UK edition of SNOMED CT also contains the UK extensions. These provide terms specifically required in the UK, such as UK screening procedures, assessment scales and British English spellings.
