A GP finishes a consultation, dictates a referral letter, and hits send. From the GP’s perspective, their job is done. The patient walks out assuming an appointment will materialise. And at the specialist practice on the receiving end, a process kicks off that most people — including many of the patients and GPs involved — have never fully mapped out.

That process has eight stages. Each one has a specific purpose, a specific failure mode, and a specific person who’s supposed to be paying attention. Here’s what actually happens.

Stage 1: The GP writes and sends the referral

The journey starts in the GP’s consulting room. The doctor composes a referral letter — sometimes a detailed clinical summary, sometimes a single sentence — and sends it to the specialist practice.

How it’s sent matters more than you’d think. In 2026, referrals arrive by secure messaging (like Medical Objects or Argus), email, fax, and occasionally post. Some GP clinics use electronic referral platforms. Others print and fax. A surprising number still post letters.

Where it goes wrong: The referral is sent to an old fax number. The email bounces. The letter is addressed to a doctor who left the practice two years ago. The GP’s software auto-populates an outdated provider number. The referral was “sent” but the GP’s outbox didn’t actually transmit. None of these failures generate an error message that anyone checks.

Stage 2: It arrives at the specialist practice

The referral lands somewhere in your practice. But where?

If it came by fax, it’s sitting in a fax tray or a digital fax queue. If it came by email, it’s in a shared inbox — possibly among dozens of other messages. If it came via secure messaging, it’s in whatever platform your practice uses. If it came by post, it’s in a pile of envelopes on someone’s desk.

Where it goes wrong: The referral arrives, but nobody is specifically responsible for checking that particular channel at that particular time. Faxes received after 5pm sit overnight. Emails arrive over the weekend. A referral can be physically present in your practice and functionally invisible — received by the system but not yet seen by a human.

This is the first critical handoff, and it’s where the clock starts ticking. Research suggests your best conversion window is within the first 72 hours.

Stage 3: Someone triages it

A team member — usually a practice manager or senior receptionist — opens the referral and makes three decisions: Is it complete? How urgent is it? Which doctor should see this patient?

Triage is where clinical knowledge and administrative skill intersect. The person triaging needs to understand enough about each doctor’s scope and availability to route the referral correctly, and enough about clinical urgency to flag anything that shouldn’t wait.

Where it goes wrong: The triage decision is often made by whoever happens to be free, which means consistency varies. A referral marked “routine” by one staff member might be flagged as “semi-urgent” by another. If your triage criteria aren’t documented, every staff member is applying their own judgement — and that judgement changes depending on how busy the day is.

Incomplete referrals create a particular problem at this stage. The letter mentions imaging results but doesn’t include them. The Medicare number is missing. The clinical notes are too vague to determine urgency. The referral gets set aside in a “needs follow-up” pile — which, in many practices, is where referrals go to age quietly until someone remembers they exist. We’ve covered what happens when these pile up.

Stage 4: The referral is assigned to a specialist

Once triaged, the referral needs to land on a specific doctor’s list. In a solo practice, this is automatic. In a multi-doctor practice, it’s a decision that involves matching the clinical presentation to the right specialist, checking availability, and considering patient preferences.

Where it goes wrong: The assignment happens informally — someone mentions it to the doctor in passing, or drops the letter in their pigeonhole. There’s no record of when it was assigned, and no system to flag if the doctor hasn’t reviewed it. A referral assigned to a doctor who’s on leave for two weeks will sit in a pile for two weeks — and nobody monitoring the pipeline will know it’s stalled, because it technically has an owner.

Stage 5: The doctor reviews and accepts (or declines)

The specialist reads the referral and decides: accept the patient, request more information, or decline and redirect. This is a clinical decision, but it has administrative consequences.

If accepted, the referral moves forward. If more information is needed, someone has to go back to the GP — and the referral re-enters a waiting state. If declined, the GP needs to be notified so they can refer elsewhere.

Where it goes wrong: Doctor review is often the slowest stage in the pipeline. Specialists are busy seeing patients, and reviewing incoming referrals competes with their clinical workload. Some doctors review daily. Some review weekly. Some review when the pile gets tall enough to topple.

There’s rarely a defined turnaround expectation. And when a doctor requests more information, the follow-up often falls into the same gap as incomplete referrals in Stage 3 — someone needs to chase the GP, and that someone needs to remember to chase.

For practices looking to streamline this step, onboarding new doctors into a structured referral workflow can make a measurable difference.

Stage 6: The practice contacts the patient

This is where the referral crosses from an internal process to a patient-facing one. Someone calls, emails, or texts the patient to let them know the practice has received their referral and to arrange an appointment.

It sounds simple. It is not.

Where it goes wrong: The patient’s phone number is wrong. They don’t answer. They don’t check voicemail. The letter is sent by post and takes three days — by which time the patient’s motivation has faded. Or, most commonly, the practice doesn’t contact the patient at all because they assume the patient will call them.

This assumption is the single biggest source of referral leakage in specialist practice. The patient was told by their GP that a referral was being sent. They’re at home, waiting to hear from the specialist. The specialist is at the practice, waiting for the patient to call. Both sides wait. Nobody acts. The referral dies in silence.

Practices that make proactive contact within 48 hours — ideally by SMS — consistently convert more referrals than those that wait for the patient to initiate.

Stage 7: Documents are collected

Before the appointment can proceed, the practice often needs supporting documents: imaging reports, blood work, prior specialist letters, surgical notes. Sometimes these were included with the referral. Usually, they weren’t.

Where it goes wrong: Document collection is the most underestimated bottleneck in the referral pipeline. It’s not unusual for a practice to have a patient ready to book but unable to schedule because they’re still waiting on an MRI report from three weeks ago. The patient doesn’t know the practice is waiting. The practice assumes the GP will send it. The GP doesn’t know it’s missing.

Each missing document requires a phone call or a fax — and each one adds days. For practices using AI document processing, some of this overhead can be reduced, but the fundamental challenge remains: someone needs to identify what’s missing and chase it.

Stage 8: The appointment is booked and confirmed

The referral has been received, triaged, assigned, reviewed, the patient has been contacted, documents have been collected — and finally, an appointment goes on the schedule. A confirmation SMS or letter is sent, and the patient knows when and where to show up.

Where it goes wrong: Even at this final stage, things can unravel. The appointment is booked but the confirmation isn’t sent. The patient receives a date that conflicts with work and doesn’t call to reschedule — they just don’t show up. The appointment is weeks away and no reminder is sent in the interim.

The referral isn’t truly “done” until the patient walks through the door. Everything before that is still pipeline.

Why mapping this matters

Most practice managers execute these eight stages instinctively. They’ve been doing it for years. They know the flow — or at least, their version of it.

But here’s what changes when you actually map it out: you start to see where time disappears. You notice that Stage 3 to Stage 5 takes eleven days on average because doctor review isn’t scheduled. You discover that 30% of referrals stall at Stage 7 because document follow-up has no owner. You realise that Stage 6 — patient contact — isn’t happening consistently because it depends on who’s rostered on that day.

A weekly referral meeting can help surface these bottlenecks. Fifteen minutes every Monday, reviewing what’s stuck and where, is enough to catch most problems before they become patient complaints.

The full picture

Eight stages. Eight potential failure points. And in most specialist practices, no single view that shows every referral’s position across all eight.

That’s the gap. Not bad people or broken processes, but a lack of visibility into a pipeline that’s more complex than it appears from the inside.

SimpleRef gives practice managers that visibility — every referral tracked from receipt to appointment, with automated alerts when something stalls. You can try it free to see your referral pipeline mapped out, or use our referral calculator to estimate what’s slipping through the gaps today.
