If you've worked in a clinical setting or you're training for one, you've probably come across the term Patient Group Direction. But what exactly is a PGD, who can use one, and when is it actually appropriate? This guide breaks it all down clearly, explaining everything you need to know about how they work under NHS rules.
The simple answer first
A Patient Group Direction is a written legal document that allows certain registered healthcare professionals to supply or administer a medicine to a group of patients without needing an individual prescription for each person.
That's the core of it. It's not a prescription, and it's not a blanket permission to hand out medicines freely. It's a carefully structured, legally authorised framework that sits between those two extremes.
Think of it this way: instead of a GP scribbling a prescription for every patient who walks in for a flu jab, a PGD allows the practice nurse to administer the vaccine directly, under a pre-approved set of clinical criteria. It saves time, reduces pressure on prescribers, and keeps patient care moving efficiently, especially in high-volume settings like vaccination programmes.
The legal definition
The legal definition comes from the Human Medicines Regulations 2012. A PGD is a written instruction for the supply and/or administration of a licensed medicine in an identified clinical situation, signed by a doctor or dentist and a pharmacist. It applies to groups of patients who may not be individually identified before they present for treatment.
That last part matters. Unlike a standard prescription, a PGD doesn't require the patient to be known in advance. The healthcare professional assesses each person against the criteria set out in the document, and if they meet the requirements, the medicine can be given there and then.
PGDs were first introduced in the UK through legislation in 2000, primarily to improve access to medicines in community settings and support large-scale public health programmes.
What must a PGD include?
A PGD isn't just any document; it has to meet strict legal requirements to be valid. Under the Human Medicines Regulations 2012, every PGD must contain:
- The name of the organisation that owns the direction
- The start and end date
- A description of the medicine(s) covered
- The specific clinical condition or situation it applies to
- Which class of healthcare professional is authorised to use it
- A description of patients who are excluded
- Dosage, strength, route, frequency, and maximum quantity
- Relevant warnings and potential adverse reactions
- Details of any required follow-up
- Record-keeping requirements for audit purposes
- A signature from both a doctor (or dentist) and a pharmacist
If any of these elements are missing, the PGD isn't legally valid.
Who can work under a PGD?
Not everyone in a clinical environment is permitted to supply or administer medicines under a PGD. The law is specific. Only qualified, registered healthcare professionals listed in the Human Medicines Regulations 2012 (Schedule 16, Part 4) can do so.
That includes:
- Registered nurses and midwives
- Pharmacists
- Paramedics
- Physiotherapists
- Occupational therapists
- Optometrists
- Dental hygienists and dental therapists
- Dietitians
- Chiropodists and podiatrists
- Radiographers
One group notably excluded: healthcare assistants (HCAs). Even if an HCA is experienced and well-trained, they cannot administer prescription-only medicines under a PGD. If medicines need to be given by an HCA, a Patient Specific Direction (PSD) must be in place instead.
Individual practitioners must also be named and authorised before they can work under a PGD. Simply being registered in an eligible profession isn't enough; the organisation must formally confirm the person is trained, competent, and authorised to use that specific PGD.
PGD vs PSD: what's the difference?
This is where a lot of confusion sets in, so it's worth being clear.
A Patient Specific Direction (PSD) is a written instruction from a prescriber, a doctor, dentist, or non-medical prescriber, for medicines to be given to a named, individual patient after that patient has been assessed. It's the more familiar model: the prescriber sees the patient, writes instructions, and another clinician carries them out.
A PGD, by contrast, doesn't require a prescriber to see the patient first. The healthcare professional working under the PGD assesses the patient themselves against the documented criteria and makes the call to supply or administer.
NICE guidance (MPG2, 2017) clearly states that individual patient care using prescriptions or PSDs should remain the default. PGDs should only be used where they practically improve care, for example, in mass vaccination clinics or sexual health services where seeing a prescriber for every patient would be impractical and unnecessary.
If a PSD already exists for a patient, there is no need for a PGD. The PSD takes precedence.
When should a PGD be used?

The NHS and NICE are clear that PGDs are not a routine workaround. A PGD is appropriate when:
- There is a defined clinical situation where a group of patients will have consistent needs
- It certainly improves care or access without compromising safety
- There is no simpler legal route already available (such as a Schedule 17 exemption)
- Proper governance, training, and accountability are in place
Common real-world examples include NHS vaccination programmes (flu, COVID-19, childhood immunisations), sexual health clinics administering emergency contraception, minor injury units giving analgesics, and travel health services providing antimalarials or vaccines.
One important point that's easy to overlook: the supply and administration of medicines under a PGD cannot be delegated. The registered professional who carries out the assessment must be the same person who supplies or administers the medicine. There's no passing it off to another colleague.
Who authorises a PGD?
In England, PGDs must be authorised by an appropriate NHS body. For GP practices delivering NHS services, this is typically NHS England or the relevant Integrated Care Board (ICB). In Scotland, Health Boards carry out this role.
GP practices can adopt pre-approved PGDs rather than building their own from scratch, but if your team needs professional support, Scripter Digital's PGD consultation flows are built to NHS compliance standards. Explore our plans to see how we can support your team.
PGDs have an expiry date, and using an expired PGD is not legally valid. If a PGD lapses and hasn't been renewed, clinicians must switch to Patient Specific Directions until the updated version is authorised.
Records relating to PGDs, including master signed copies, lists of authorised practitioners, and patient records, must be kept for eight years for adults, or until the patient's 25th birthday for children.
Governance and CQC inspections
The Care Quality Commission (CQC) inspects GP practices on their use of PGDs and PSDs, and this is an area where practices can fall short if the administration isn't properly managed. Common issues include using expired PGDs, staff administering medicines without formal authorisation, and incomplete record-keeping.
If you're a practice manager or lead nurse, a regular audit is worthwhile: are your PGDs up to date, are all relevant staff named and authorised, and are records being kept correctly?
The bottom line
Patient Group Directions are a valuable part of how the NHS delivers care efficiently and safely. They allow skilled, registered professionals to act within a clear legal framework without the bottleneck of an individual prescription for every clinical encounter.
But they come with real responsibilities. They must be properly authorised, kept current, used only in appropriate situations, and operated by trained practitioners who understand what the document does and doesn't permit.
If you're involved in developing, adopting, or working under a PGD, the NHS Specialist Pharmacy Service (SPS) and NICE MPG2 guidance are the authoritative sources to consult. When in doubt, always default to a patient-specific approach; that's exactly what the guidance recommends.
