What does “pathway” mean on an NHS waiting list?

NHS England's guidance on its waiting-time statistics defines it: “An RTT pathway is the period of time that a patient waited from referral to start of treatment, or, if they have not yet started treatment, the length of time that a patient has waited so far.” The same guidance uses “RTT clock” for the same thing.

The NHS website says your waiting time “starts from when the hospital or service receives your referral letter, or when you book your first appointment through the NHS e-Referral Service”. While you wait, you may have tests, scans or other procedures, have medicine or therapy to manage your symptoms, or be referred to another consultant or department. The wait ends “if a clinician decides no treatment is necessary, if you decide you do not want to be treated, or when your treatment begins”.

Each pathway belongs to one referral. NHS England's guidance says: “A patient can be on more than one RTT pathway at the same time if they are waiting for consultant-led elective treatment for different conditions or unrelated clinical reasons. Some patients will therefore be included in the RTT pathway figures more than once.”

For example, someone referred to dermatology for a skin condition and to urology for a bladder problem is on two pathways, one in each specialty's figures.

So the two national numbers differ. At the end of August 2026 NHS England put the waiting list in England at 7.4 million pathways, and estimated the number of people waiting at around 6.2 million. The estimate comes from the Waiting List Minimum Data Set, which on 30 August 2026 showed 85 different NHS numbers for every 100 pathways (NHS England statistical press notice, August 2026).

NHS England publishes the waiting list split by specialty, which it calls a treatment function. A “gastroenterology pathway” or a “urology pathway” is a wait counted in that specialty's figures.

It reports 18 specialties separately, “chosen as areas with a large volume of RTT pathways”, and puts all the others into five “Other” groups. HospitalWaits compares hospitals in those 18. Vascular surgery, for example, is not one of them, so its pathways are counted in one of the “Other” groups.

Six of the 18, each with its waiting list by hospital:

• Gastroenterology waits by hospital
• Urology waits by hospital
• Neurology waits by hospital
• Neurosurgery waits by hospital
• Plastic surgery waits by hospital
• Dermatology waits by hospital

All 18 are on the national waiting times page. On HospitalWaits, the figure labelled “On the list” on a specialty's national page and on a hospital's specialty pages is this count of pathways, from NHS England's data. The diagnostic test tables use the same label for the number waiting for each test, which comes from NHS England's separate monthly diagnostics data. How we use the data, and its limits, is on the methodology page.

The Handbook to the NHS Constitution gives you the right to “start your consultant-led treatment within a maximum of 18 weeks from referral for non-urgent conditions”, with exceptions. A referral for a different condition starts its own pathway, with its own 18 weeks.

If your hospital refers you on to another consultant or another hospital for the same problem while you are still waiting to start treatment, the count does not start again. NHS England's rules for recording waiting times say that “a new RTT clock would not start” for a referral “part-way along an RTT pathway”, and that when your care moves to another hospital, the hospital that refers you on must pass on the date your clock started. If you are not sure which start date has been recorded for you, ask the hospital.

If you have waited longer than 18 weeks, the waiting list guide explains how to ask for another hospital and how to complain. Choosing a hospital when you are first referred is covered in Right to Choose.

Is a pathway the same as a person on the waiting list?

No. A pathway is one referral's wait, and one person can be on more than one. NHS England's guidance says some patients are included in the pathway figures more than once. At the end of August 2026 NHS England put the waiting list in England at 7.4 million pathways, and estimated that around 6.2 million people were waiting.

Can I be on more than one NHS waiting list at the same time?

Yes. NHS England says a patient can be on more than one referral-to-treatment pathway at the same time if they are waiting for consultant-led elective treatment for different conditions or unrelated clinical reasons. Each pathway is counted under the specialty it belongs to.

When does a pathway start and stop?

The NHS website says your waiting time starts from when the hospital or service receives your referral letter, or when you book your first appointment through the NHS e-Referral Service. It ends if a clinician decides no treatment is necessary, if you decide you do not want to be treated, or when your treatment begins. The NHS website lists tests and scans among the things that can happen while you wait.

What does 'incomplete pathway' mean?

It is NHS England's term for a wait that has not finished: the patient is still waiting to start treatment at the end of the month. People on an incomplete pathway may be waiting for tests, an appointment with a consultant, or admission for a procedure. The number of incomplete pathways is what is reported as the size of the waiting list.
