Perverse waiting list management, despite the promises

Perverse waiting list management, despite the promises

I’ve been banging on about England’s perverse waiting times targets for years now, and although things have been getting better it’s always ‘two steps forward, one step back’. So I was very encouraged by the health secretary Jeremy Hunt’s words at the Royal Surrey on the 4th of August. Apologies for quoting him at such length, but this is important and I think it’s worth it:

When the NHS started measuring performance against the 18 week target in 2007, something perverse happened. If faced with a choice between treating a patient who had missed the 18 week target or someone who had not yet reached it, the incentive was to treat the person who had not yet missed the target rather than someone who had – because that would help the performance statistics, whereas dealing with the long waiter would not. So a target intended to do the right thing ended up incentivising precisely the wrong thing.

I couldn’t have put it better myself. He went on…

I want the NHS to put particular focus on anyone who has been waiting more than 18 weeks since being referred for treatment, so have asked NHS England to commission 100,000 additional treatments over the summer including 40,000 additional inpatient admissions.

This focus on long waiters may mean we undershoot the 18 week target for a temporary period, although we will return to meeting it before the end of the year. Indeed as the many NHS target experts will know we could ensure we met the 18 week target every month by focusing those 100,000 additional treatments on shorter rather than longer waiters. But that would be an indefensible betrayal of those who have been waiting the longest and not one I would be prepared to sanction as Health Secretary.

The truth is we need to ensure both that 90% of people get their treatment within 18 weeks – the official target – and that people who are not treated within that period are not neglected. So I have set a timeframe of this calendar year to deliver on both of those objectives.

I take that to be a very clear commitment to stop perverse waiting list management, especially during the national waiting list initiative which began in July, and to treat the longest-waiting patients even if that causes a breach of the adjusted admitted or non-admitted targets.

The July figures are now available, so let’s see if the promise was delivered.

The three tests of perverse waiting list management

I am going to apply quite a strict test for detecting perverse waiting list management to minimise the risk of false positives. A service (i.e. a specialty within a Trust) is only tagged with detected perverse waiting list management if all three of the following conditions are satisfied:

the perverse ‘adjusted admitted’ target was achieved during the month, showing that lots of short-waiters were admitted (Trusts can be fined £400 per patient for admitting too many long-waiting inpatients and daycases); and
the perverse ‘non-admitted’ target was achieved during the month, showing that lots of short-waiters were treated or discharged in outpatients (Trusts can be fined £100 per patient for seeing too many long-waiting outpatients – this target is less of an issue in most services); and
the much better ‘incomplete pathways’ target was breached at both the start and the end of the month, showing that there were plenty of long-waiters on the list who should have been treated instead (Trusts can be fined £100 per patient if too many patients are still on the list for more than 18 weeks at the end of each month).

The adjusted admitted target is significantly tougher than the incomplete pathways target, so if a waiting list is too big to sustain even the incomplete pathways target then there is no way it should be able to sustain the more difficult adjusted admitted one. So these should be pretty good tests.

For belt and braces, the interactive map below includes links to a full analysis of each service’s waiting times statistics so that all the available detail can be scrutinised in each case.

Whose fault is it?

Whose fault is it when perverse waiting list management takes place?

It would be easy to rush to blame the hospital, but that would be unfair. Remember, they are used to facing huge fines and regulatory action for breaching these targets, and if ‘the system’ is pushing so hard for the achievement of perverse targets then it is hard to blame the hospitals for complying.

If the hospital did not in fact face penalties or regulatory action for breaching the perverse targets, and if that was clearly communicated to them in writing by the various penalisers and regulators, then it would be fair enough to lay the blame at the hospital’s door. But we know that matters were often far from clear in July and so any blame should be spread more widely to those who determine and apply the incentives up and down the system.

Services where perverse list management was detected

In the latest (July 2014) statistics published by NHS England, the tests were applied to 1,438 services that had decent numbers of admitted activity and waiting list sizes. Of those services, 324 (23 per cent) breached the incomplete pathways target at the end of July (which means that more than 8 per cent of patients on the waiting list were waiting longer than 18 weeks). Of those services, 21 (6 per cent) were detected according to the tests as apparently having perverse waiting list management.

So with all the preambles and caveats, here they are.

[UPDATE: The following table is July 2014 data. See the “Local detail” section of the latest monthly waiting times reports for updated data. For instance the August 2014 data is here and the map is here]

And here is an interactive map of the same services, including links to a fuller analysis of each service’s waiting times data:

Of course if any of these hospitals believes that I have made a mistake and it has been incorrectly included then I would be grateful for their comments on this analysis.

What should be done?

It is time for the health secretary to deliver on his fine words.

Hospitals should not be pushed into perverse waiting list management. The penalties for treating long-waiting patients should be minimised or abolished and the focus should be on treating those long-waiting patients who are still waiting.

If that cannot be done quickly, then CCGs and regulators should go easy on well-planned breaches of the perverse targets so that hospitals are not deterred from treating their longest-waiting patients as part of an orderly recovery process.

I don’t believe that anybody in the NHS wants to see perverse waiting list management. Yet somehow the incentives for it keep coming back with renewed vigour. It’s time to stop. Hospitals need to know that they can treat their longest waiting patients without being clobbered for it.
