How NHS MSK triage works.
What NHS MSK triage is
NHS MSK triage is the step that decides what happens next for a patient with a musculoskeletal problem, meaning a problem with the joints, muscles, bones or soft tissues. MSK is the standard NHS abbreviation.
Every triage decision answers three questions: how urgent the problem is, who the patient should see, and what should happen first so the next appointment is useful. NHS England notes that most community MSK services have a triage function to support diagnosis and make sure referrals go to the right place.
This page is for the people who run and fund those services. If you want the basics first, read MSK triage explained. If you are comparing software, read what an MSK triage tool should do.
The three places it happens
In general practice
Adults in England can see a first contact practitioner (FCP) at their GP practice without being referred by a GP. Most are physiotherapists with enhanced skills, who assess, diagnose, advise and refer on where needed. We explain the roles in first contact practitioners, explained.
In community MSK and interface services
These sit between general practice and hospital. NHS England's community MSK service specification asks them to deliver high quality triage to support diagnosis and make sure referrals go to the right place. We describe them in MSK triage explained.
At the hospital
Referral letters are reviewed before the patient is booked. NHS England lists the routes: referral assessment services in the NHS e-Referral Service, clinical assessment and triage services (CATS), and referral management centres. We cover this in MSK referral optimisation.
What NHS England asks services to do
Three NHS England documents shape MSK triage today.
The referral optimisation guidance (October 2023). Its aim is that people are seen by the right person, at the right time and in the right place. It recommends specialist advice before or instead of a referral, ideally within two working days, and says this should not prevent or delay a referral that is in the patient's best interest.
The adult community MSK service specification (July 2026). It sets the minimum standards a community MSK service is expected to meet. Services should spot warning signs of urgent and emergency conditions, in line with guidance from the National Institute for Health and Care Excellence (NICE), and refer those patients on. They should also have an agreed process for referral to orthopaedics, spinal, pain and rheumatology services.
The improvement framework to reduce community MSK waits (January 2023, updated December 2025). It asks that no priority patient waits more than two weeks, and that no patient waits longer than 52 weeks.
What services are measured on
The national measure is waiting time.
Every community MSK service must report its waits in NHS England's monthly community health services situation report. The service specification sets the target: at least 78% of community health service activity within 18 weeks by the end of 2026/27, and 80% by the end of 2028/29, with no patient waiting over 52 weeks.
The same specification asks services to collect a patient reported outcome measure (PROM), such as the Musculoskeletal Health Questionnaire (MSK-HQ), and a patient reported experience measure (PREM). Local indicators are agreed between the service and its commissioner.
The specification also suggests local measures. One comes close to the question that matters: the proportion of patients discharged after their first consultant appointment, which NHS England calls a gateway measure of whether referrals into hospital are right. Waiting times count how long patients waited. That measure starts to show whether the wait was needed.
Two ways a triage decision can go wrong
A specialist wait that changed nothing
A patient is sent for a surgical opinion they did not need. They wait months, and the appointment ends in advice that could have been given at the start.
A delayed escalation
A patient who needed a surgeon is kept in non-surgical care for too long. Nothing visibly goes wrong, so it is rarely counted.
Both start in the same place. Most triage questions sit well within an experienced physiotherapist's expertise. The surgical question is different: the thresholds a surgical team applies, and what happened to each referral, are rarely in front of the clinician making the decision. NHS England notes that specialist advice is often sought informally between clinicians.
Surgical decision support inside NHS MSK triage
Most tools built for MSK triage aim to keep people out of hospital. Orwyn helps the clinician decide when a patient should go in, when they should not, and gives the clinician and the patient a reason to trust the answer.
Orwyn is designed for the clinician to use in the consultation. It asks the safety questions first, then shows the most likely diagnosis with its reasons, the test to request, and whether and how urgently a surgeon is needed. The clinician can agree or disagree, and a disagreement is recorded, never overridden.
Orwyn is currently being assessed for an NHS pilot to test its safety, clinical effectiveness and cost effectiveness.
How a service could evaluate it is on working with the NHS. There is also a page for patients that explains what Orwyn is.
Questions service leads ask
What is NHS MSK triage?
NHS MSK triage is the step that decides what happens next for a patient with a musculoskeletal problem: how urgent it is, who the patient should see, and what should happen first so the next appointment is useful.
Who does MSK triage in the NHS?
Mostly experienced physiotherapists: first contact practitioners in general practice, and advanced practice and consultant physiotherapists in community MSK and interface services. At the hospital end, consultants and senior clinicians review referral letters.
What are NHS MSK services measured on?
Nationally, on waiting times reported in NHS England's monthly community health services situation report. NHS England's community MSK service specification also asks services to collect patient reported outcome and experience measures, and to agree local indicators with their commissioners.
Is Orwyn an NHS MSK triage tool?
Orwyn is designed for use inside MSK triage, but it is not a patient triage app and it is not provided by the NHS. It is surgical decision support for the clinician at first contact: it shows the most likely diagnosis with its reasons, the test to request, and whether and how urgently a surgeon is needed. The clinician makes every decision. Orwyn is built by Orwynhealth Ltd, an independent company.
Is Orwyn artificial intelligence?
No. Orwyn runs on rules a named consultant surgeon has written and signed off, built from national guidance and research evidence. It is not a model whose reasoning cannot be inspected: anyone reviewing a decision can be shown why it was made.
