GP Referral Letter Template: Routine, Urgent, and Abnormal Findings

In England, most urgent suspected cancer referrals do not involve writing a letter from scratch. The GP completes structured fields on a site-specific form, usually through e-RS or a SystmOne/EMIS template, and the cancer pathway team receives the referral electronically. Local cancer referral forms do most of the structural work.

The situations where you actually need to write a referral letter are different, and often harder: a routine specialty referral where the clinical reasoning is yours to construct; an urgent referral that does not sit on a predefined pathway; an unexpected finding that needs specialist eyes quickly; or an Advice & Guidance request where you need a specific clinical question answered rather than a formal referral booked.

This article covers all four.

When You Write a Letter vs Fill a Form

You fill a structured form (system template or e-RS):

• Urgent suspected cancer referrals (2WW / Faster Diagnosis Standard) — most sites use structured local forms with defined fields
• Specific pathway referrals with ICB-mandated templates, such as heart failure, diabetes, and some musculoskeletal pathways

You write a letter (or compose free text):

• Routine outpatient referrals to any specialty where no pathway form exists
• Urgent non-cancer referrals where the local pathway does not already define the information set, such as new AF, suspected TIA, unexplained syncope, acute psychiatric deterioration, or abnormal findings requiring prompt review
• Advice & Guidance (A&G) requests via e-RS — a free-text specialist question with relevant background
• Letters accompanying patients being sent directly to A&E or acute services

The clinical letter exists precisely because the clinical picture does not fit a structured form. Getting it right matters. Secondary care cannot triage on “patient unwell, please assess” or “please do the needful” when the GP clearly knew something was wrong but had no time or structure to explain what.

The purpose of a good referral letter is not to demonstrate thoroughness. It is to transfer enough clinical reasoning that the receiving clinician can make a fast, informed decision without calling you back.

What Every Referral Needs to Answer

Regardless of type or urgency, any referral letter should answer:

1. Who is this patient? Demographics, relevant comorbidities, functional status.
2. Why are you referring now? The specific finding, symptom pattern, or clinical concern that triggered this.
3. What context does the specialist need? Relevant positives, relevant negatives, investigations already done, medication.
4. What do you want them to do? Assessment only, specific investigation, treatment initiation, opinion on management.

Specialists receiving a letter without a clear request may delay, redirect, or reject it. “Please see and advise” is often not enough. “Please assess and consider CT pulmonary angiogram” or “please review for possible rheumatological cause and advise on investigation pathway” gives a triage team something to act on.

Urgent Referrals That Are Not Cancer Pathways

Urgent non-cancer referrals are the most common situations where clinical letter writing matters. There is no universal predefined form telling you what to include, but the clinical stakes may be just as high as any urgent cancer pathway.

The key difference from a routine referral: urgency must be visible in the letter, not just implied by the word “urgent” in the subject line. Show the urgency through the clinical picture.

Examples of how to show rather than declare urgency:

Weak:

Please urgently review this patient with chest pain.

Stronger:

New-onset exertional chest pain with diaphoresis, duration 72 hours. ECG today: new 1mm ST depression in leads V4-V6. Troponin result pending. Aspirin 300mg given. Patient reviewed this morning and requires same-day cardiology assessment.

The stronger version tells the receiving team what you found, what you did, what is pending, and what you need. It also documents your clinical management, which matters for both continuity and medicolegal reasons.

For urgent referrals, additionally include:

• Time-sensitive information first: findings, observations, actions already taken
• Which specific investigations are pending and when results are expected
• Anticoagulation and medication relevant to the acute picture
• Whether the patient is being sent in or attending outpatients

Abnormal and Unexpected Findings

An abnormal finding that arrives after the consultation — an unexpected result, an incidental finding on imaging, a result flagged by the lab — is one of the most common scenarios where there is no template and the clinical urgency is unclear.

Examples:

• Incidental pulmonary nodule on a CT chest done for another indication
• PSA significantly higher than expected, not previously discussed with the patient
• Unexpected bone lesion found on a pelvis X-ray
• FBC showing unexplained lymphocytosis or thrombocytopenia
• Haematuria on a urine dip done for UTI investigation in a 65-year-old man

For these, the referral has two jobs: communicate the finding clearly, and explain the clinical context.

RE: Urgent review — unexpected finding — [brief descriptor]

Finding:
- What was found (with values/measurements):
- Which investigation, ordered for what indication, on what date:
- Whether this was incidental or related to the presenting complaint:

Clinical context:
- Brief relevant history:
- Any symptoms that may now be related:
- Examination findings:

Current status:
- Has the patient been informed? What were they told?
- Any further investigation already arranged:
- Safety-netting given:

Request:
- What you need the specialist to do:
- Your view on urgency (and why):

The patient communication section matters particularly here. If the patient does not yet know about the finding, state that clearly — “patient not yet informed, pending this referral” — so the specialist knows the conversation has not happened. Sending a patient to a clinic they do not understand because a letter was sent before they were told is a significant patient experience failure, and a common one.

Advice & Guidance Requests

Advice & Guidance (A&G) is a two-way digital conversation through e-RS between a referring clinician and a specialist. It is not the same as a booked referral, unless the request is converted into a referral through the e-RS process. Used well, it resolves clinical uncertainty without adding avoidable outpatient appointments.

Use A&G when:

• You are uncertain whether a formal referral is appropriate
• You want specialist input on a management decision or investigation plan
• You need clarification on an abnormal result before deciding what to do next
• You want advice on the correct pathway for a patient

Do not use A&G when:

• The patient needs to be seen — use a referral
• The question is urgent and requires a same-day response — phone the specialist directly
• The patient clearly meets urgent suspected cancer criteria — use the cancer referral pathway, not A&G

A good A&G request has a specific specialist question at the top.

ADVICE AND GUIDANCE REQUEST — [Specialty]

Clinical question:
[State the specific question you need answered. E.g., "Is this patient's calcium level
(2.78 mmol/L) significant enough to warrant formal endocrinology referral, or is primary
care management appropriate?"]

Background:
- Age, sex, relevant comorbidities:
- Presenting complaint and duration:
- Relevant examination findings:
- Results (with values and dates):
- Current medications:

What I have done so far:
- Management steps already taken:
- Any referrals already made:

What I am asking for:
- Specific advice on [investigation / management / referral appropriateness]:

The RCGP argues that clinical care governance and risk should be shared between primary and secondary care during A&G conversations. NHS e-RS guidance also makes clear that an A&G request is not automatically a formal referral; where referral is needed, responsibility for making or authorising that referral must be clear. Document the advice received and your response to it in the patient record.

Relevant Negatives: What They Are for

Relevant negatives are not padding. They show the specialist that you considered and actively excluded important alternative features.

For a neurology referral for headache: you asked about and confirmed the absence of thunderclap onset, fever, focal neurology, and papilloedema on fundoscopy.

For a cardiology referral: you established the absence of prior cardiac history, previous troponin results, and checked for drug causes.

Two rules that apply to all referral types:

Only document negatives you specifically asked about. If you did not check for it, do not document its absence.

If a relevant feature is unknown or was not checked, write “not yet ascertained.” Gaps matter — the specialist needs to know what remains unknown, not have those gaps silently omitted.

Patient Communication and Safety-Netting

For all urgent referrals — cancer pathway or otherwise — tell the patient what you are doing and why before sending the referral. A patient who receives an appointment letter from a hospital specialty clinic they were not expecting may not attend, or may attend without understanding what the investigation is for.

What to cover before sending any urgent referral:

• Why you are referring and what the specialist will do
• The likely timeframe for contact
• What the patient should do if symptoms worsen before the appointment
• What to do if they do not receive contact within the expected timeframe

Document the substance of this conversation in the referral letter itself:

Patient informed of referral and reason. Understands the hospital may contact them within [timeframe]. Advised to seek urgent review if symptoms worsen or new symptoms develop. Advised to contact the practice if no hospital contact within [local timeframe].

Common Failures

Stating “urgent” without showing the clinical picture. The word urgent is a flag, not a clinical argument. The case for urgency is in the findings.

Omitting what you actually want. “Please see and advise” is frequently the entire request on a referral. Specialists prefer “please assess and consider CT head” or “please advise on whether this warrants bronchoscopy.”

Pasting results without interpreting them. “Hb 74, ferritin 4 mcg/L” communicates more to a triage team than “blood tests attached.”

Not documenting what the patient was told. Particularly for abnormal findings and unexpected results, the letter should state whether the patient has been informed, what they were told, and what safety-netting was given.

Sending to the wrong pathway. A letter directed to the wrong specialty, or to a general mailbox rather than the correct pathway, may sit without action. Check the correct e-RS service or local referral route before sending.

AI draft sent without review. A referral letter is a clinical document. Every clinical statement, result, and urgency assessment needs checking against the actual patient record.

Using ClinicQuest for Referral Drafting

Clinical Drafting turns fictional or fully anonymised case material into a structured first-draft example — for urgent referrals, routine referrals, and A&G-style requests. The draft opens in an editable workspace alongside your conversation; you review it before using any text outside ClinicQuest.

The tool includes missing-information prompts and red-flag prompts. If relevant information is absent from the draft example — a missing allergy field, an undocumented safety-netting line — those gaps are flagged as reminders, not validation or safety assurance.

A practical workflow:

1. Gather the learning material from fictional or fully anonymised notes.
2. Describe the anonymised case to the assistant and ask for a referral example — specify the type (routine / urgent / A&G).
3. Review every clinical statement, result, and urgency assessment before using the text outside ClinicQuest.
4. Move the reviewed text into your own clinician-led drafting workflow if appropriate.
5. Use Tasks to log any personal learning or admin follow-up.

The assistant can also help you review which pathways or specialties are described in UK guidance, or how A&G requests are usually structured. It searches NICE, BNF, and NHS guidance as part of that conversation.

Clinical Drafting reduces blank-page friction and structures educational examples. It does not send letters, verify clinical accuracy, or substitute for your judgement on urgency.
