How the media talks about waiting lists, and how the public understand them tend to imply that people are, in the main, waiting for hospital admission, but this does not tell the whole story. Some are waiting for further diagnostics or decisions before treatment can commence, and others are waiting for treatment that does not require admission to hospital.
Only 15 per cent of those on the waiting list have had a decision made to admit them to hospital for treatment. This varies by type of treatment;1 unsurprisingly there is a correlation between surgical treatments (ie, treatments that cannot happen outside a hospital setting) and a decision to admit.
So, what is happening for the other 85 per cent of the waiting list?
Many will be waiting for diagnostics or a decision to treat. Without these, they cannot receive definitive treatment of any kind. The above chart shows that even for surgical treatments, less than half of those on the waiting list have had a decision to admit to hospital, suggesting that a substantial portion of the waiting list are waiting for tests or decisions. So, is there a bottleneck at this stage that is contributing to the overall waiting list?
Once a patient has received a diagnosis, a decision to treat is then made. Not all these treatment decisions will require an inpatient stay. Looking at those who were treated in September 2022, it is possible to get an idea of the percentage who do need inpatient treatment: 21 per cent of treatments in that month were admitted and 79 per cent non-admitted. Extrapolated to the waiting list as a whole, this equates to several million people who are not waiting for inpatient treatment.
Looking at cardiac treatment as an example, there are currently 349,000 people on the cardiothoracic surgery or cardiology waiting lists. Of these, 34,000 have had a decision made to admit for treatment, leaving 315,000 waiting for diagnostics, decisions, or for outpatient treatment.
The NHS diagnostics data shows 160,000 people waiting for cardiology diagnostics. While this does not map perfectly – some of those waiting for cardiac treatment will also be waiting for other diagnostics, and some waiting for cardiac diagnostics will not yet be waiting for treatment – it makes the point that a substantial number of people on the cardiothoracic surgery and cardiology waiting lists are waiting for diagnostics. And a substantial number (around 155,000) remain, waiting for decisions, outpatient treatment etc.
This example demonstrates that a significant portion of those on the waiting list are either waiting for diagnostics and decisions, or for non-admitted care. Attention therefore needs to be given to the provision of diagnostic availability and outpatient care; without improvements in these areas the waiting list will continue to grow.
Much of the debate on hospital waiting lists has centred on treating those who have been waiting a long time, or the availability of hospital beds, or the need to build new surgical hubs. While these are of course important areas, there are other issues that need to be addressed. It is important not to concentrate on hospital admissions at the expense of outpatient treatment, given the numbers waiting for the latter.
And perhaps too much of the debate has centred on treating patients rather than diagnosing them. Without knowing what is wrong with a patient, or making a decision on what they need, it is impossible to treat them (or to reassure them if test results come back clear). Access to diagnostics therefore needs improvement, as our recent work on community diagnostic centres has suggested – without a diagnosis, how can the NHS know who to treat?
- 1The hospital waiting list is comprised of approximately 7 million pathways. An individual may be on more than one care pathway if they have multiple treatment needs.
This list also excludes those waiting dental work. The popular view here in Plymouth is at least ten years to get on a list, not treatment. No NHS dentists are taking on and emergency appointments are weeks when the person is in pain. Dentists used to spot other problems but only those who can afford private can access these. I am paying for private for shared care treatment with my GP for another issue, I was referred in 2015 and discharged without being treated. Now we have over 600,000 new patients to look after. How?
