Triage means different things in different corners of the NHS. In one borough it is a physiotherapist reading referral letters. In another it is a face-to-face assessment clinic. In a third it is a telephone call, or a form, or a consultant sorting a queue. Everyone in musculoskeletal care talks about triage, and almost nobody stops to say which kind they mean.
This page sets out what MSK triage actually is, where it happens, who does it, and what a good triage decision has to get right. It is written for clinicians working in or alongside these services, for medical and surgical colleagues who were never taught how the front of the pathway works, and for the commissioners and managers who fund it. Musculoskeletal means the joints, muscles, bones and soft tissues; MSK is the standard NHS abbreviation.
Strip away the local variations and every MSK triage decision answers the same three questions. How urgent is this problem? Which service or clinician should see this patient? And what needs to happen before that appointment, such as an X-ray or blood tests, so the appointment is useful rather than wasted?
The stakes are not administrative. The answer decides whether someone with a problem that needs a surgeon joins the right queue now or discovers the right queue months from now, and whether someone who will never need an operation starts proper treatment this week or waits months to be told what could have been said at the start.
The newest and fastest-growing form: a first contact practitioner appointment, where a patient books straight in with an experienced musculoskeletal clinician, usually a physiotherapist, instead of a GP. The assessment and the triage decision happen in the same room, in the same appointment. We explain these roles fully on our MSK roles page.
Interface services, in some areas called clinical assessment and triage services (CATS), sit between general practice and hospital. Advanced practice clinicians review referrals, assess patients face to face, arrange investigations and injections, and decide who genuinely needs a hospital opinion. NHS England's community MSK service specification describes this tier.
Referral letters arriving at an orthopaedic department are usually reviewed and sorted, by consultants or senior clinicians, into urgent and routine, right clinic and wrong clinic. This is orthopaedic triage in its oldest form, done on paper, often without ever seeing the patient.
Physiotherapy triage means triage done by physiotherapists, in person, by telephone or on paper, and in much of the NHS it is the main form of MSK triage. Orthopaedic triage is the part that answers one specific question: does this patient need to see a surgeon?
That distinction matters more than it looks. Most triage questions sit comfortably within an experienced physiotherapist's expertise. The surgical question is different, because the clinician asking it almost never sees the surgical end of the pathway: they do not routinely see which of their referrals end in an operation, which are sent back, and what the surgeon looked for. The specialist thresholds being applied downstream are not consistently visible to them, and the outcome of each referral is not routinely returned. That is not a criticism of the workforce; it is the structure of the system they work inside.
In practice most MSK triage is done by experienced physiotherapists: first contact practitioners in general practice, and advanced practice physiotherapists in community MSK and interface services. Depending on the local pathway, GPs, podiatrists, osteopaths, sports and exercise medicine doctors and, at the hospital end, orthopaedic consultants reviewing referral letters all take part.
Triage is usually judged on one number: how many referrals it deflects. That is half a measure. A triage decision can fail in two directions, and only one of them is ever counted.
Send a patient towards surgery who does not need it, and they wait months for an appointment that ends in discharge, in front of someone who did need it. Hold a patient in non-surgical care whose problem needed a surgeon, and a treatable problem is given time to become a permanent one. Good triage is not fewer referrals; it is the right next step, in both directions, decided early. Surgery when it's needed. Certainty when it's not.
Referral optimisation is NHS England's name for making sure patients are referred to the right service, with the right information, at the right time, including using specialist advice and guidance before or instead of a referral. NHS England's musculoskeletal guidance points to the same conclusion this page does: the clinicians who see musculoskeletal patients first make better decisions when specialist advice is available to them at the point of decision, rather than months later at the end of a referral.
Today that advice mostly travels informally, through an email to a consultant the clinician happens to know. Formalising it, so that every clinician doing MSK triage can reach surgical judgement at the moment the decision is made, is the gap Orwyn is built to close. We explain the wider policy in MSK referral optimisation, and the category of software in what MSK clinical decision support is.
