This service accounts for 3.3% of everyone waiting at Imperial College Healthcare NHS Trust.

How we calculate change
  • Each month's figure is the number of people waiting under 18 weeks divided by everyone on the waiting list, from NHS England's published monthly files.
  • Changes compare the latest month with exactly 3, 6 and 12 months earlier, only where both months are published and the list has at least 50 people.
  • The 12-month label is "improved" or "deteriorated" only if the share moved by 3 percentage points or more; smaller moves are called "broadly stable".
  • Where NHS England reissued a month's file, we use the revised file. Months we do not have are left as gaps and never estimated.
  • Earlier months come from our archive of NHS England's published files and are checked against our current figures wherever both exist.

What these figures cannot tell you

  • These are whole-list figures for one specialty at one organisation. They describe the published waiting list, not how long any one person will wait.
  • This specialty covers many conditions and treatments. These figures are not specific to any one operation or condition.
  • Figures are published for the whole organisation, which may run several hospital sites. They do not show the position at any single site.
  • Patients are prioritised by clinical need, so people on the same list can wait very different times.
  • A higher share within 18 weeks is not a measure of the quality of care.

What these figures cannot tell you

  • Where you are in a queue, or when you will be seen or treated.
  • How urgent your own referral is. These are aggregate waiting-list figures and do not show the clinical priority of an individual patient.
  • Anything about a specific consultant, clinic or site within a trust.
  • What will happen next month: these are end-of-month snapshots of a past period.
