As the potential to provide better and better healthcare keeps growing, with new techniques and drugs constantly arriving on the market, so does the pressure to control healthcare costs.
Understandably. No-one has ever worked out the maximum a society can spend on healthcare. With the United States nudging towards 20% of GDP, it is reasonable to wonder at what point will its expenditure be so high that it can no longer spend sensible amounts on other key areas, whether it’s education or even roads - or, and this is particularly sensitive in the US, defence.
But there's nothing simple about controlling healthcare expenditure. Not if we are also going to keep taking advantage of the latest advances and maintaining the best quality of care possible.
From the point of view of the information professional, both imperatives offer opportunities: any drive in either area depends on having access to reliable information.
Take an obvious way of cutting out waste and improving care: eliminating unnecessary treatment.
Why is a patient who has been put on a course of drugs by a GP on Tuesday turning up at Accident and Emergency in the local hospital on Thursday? Is he just expressing his lack of confidence in the GP? Or was the drug regime taking so long to improve his condition that he felt the need for hospital care?
Either way, what has happened has been a waste of resource.
What makes the information angle interesting, however, is the question of how the GP finds out in the first place. Somehow we need to alert her that the patient she saw one day turned up two days later at the hospital. That means marrying the record in the Primary Care system with another in the Hospital’s A&E system.
Which means sharing information by which the patient can be identified.
Healthcare information professionals have wanted to do just that for many years. Unfortunately, such information sharing conflicts with the justifiable anxiety of patients over different bodies swapping identifiable information about them. And the process of linking the information may even involve a non-NHS organisation, such as the company I happen to work for.
The concern is understandable because there have been such scandalous breaches of confidentiality of patient information. Lost USB keys, disks going astray, stolen laptops with unencrypted data. As a simple citizen and potential patient, I’m not happy that data about me may be floating around in this uncontrolled way.
So a series of legislative initiatives have made it increasingly difficult to share healthcare information. The Data Protection Act, the European Convention on Human Rights, the Statistics and Registration Services Act, even the confidentiality provisions of Common Law, mean a veritable thicket of legal restrictions makes it practically impossible in Britain to construct a service which would tell the GP about the possibly unnecessary double treatment of her patient.
All this is symptomatic of what happens when there’s an over-reaction to a scandal (or several scandals). And it has led to a conflict between principles: on the one hand, the entirely commendable protection of patient confidentiality, on the other, the legitimate use of data to inform necessary actions in healthcare.
Now it is when such conflicts arise that political and moral debates become the most interesting. To take another topical example, which has precedence, freedom of speech or the right to privacy? The trick is to get the balance right: protection of necessary privacy without excluding legitimate public information.
So I was fascinated to attend a recent meeting hosted by the NHS Information Centre and attended by representatives of the Office of National Statistics (ONS), who hold information about deaths which many of us have wanted to tie up with healthcare data for years.
It was at this meeting that I heard for the first time of a ‘Gateway’ through the confidentiality regulations.
How do we you access to that gateway? You have to complete applications, naturally - where would we be without bureaucracy? By the way, that’s not a reflection on the NHS, rather on the whole of humanity.
The application has to make it absolutely clear that you are going to use the patient identifiable data you want to handle for a specific purpose; that you will take only as much as you need for that purpose; and you will keep only for as long as strictly necessary for that purpose.
If your purpose is deemed to be legitimate, then your application will be approved and the gateway will open to you.
Now this strikes me as immensely sensible. What can one object to? As a citizen, I don’t want my personal information abused. I don’t want it held any longer than it needs to be. And I don’t want it collected for one objective and used for another.
As an information professional, I want to be able to get hold of patient identifiable data, but only to provide a specific service. How can I object to an outside body ruling on whether my purpose is reasonable? In any case, if I’m setting out to provide information to help maintain quality and control costs, that’s a double objective that we all want to achieve - as I said at the beginning - so my application is likely to be approved.
And if I’ve been given access to the data for the purpose stated, by what right can I expct to use it for any other? Or to retain it any longer than necessary?
Strikes me that we’ve found just what I said we needed when principles conflict: a point of balance.
A word of warning though: getting agreement on that balance point isn’t always easy. At the meeting I attended, the ONS representatives weren’t at all happy about releasing their mortality data. It seems that though the dead can’t be libelled - you can say what you like about them, they have no right to protect their reputation - they do have a right to confidentiality beyond the grave. And the ONS wasn’t convinced that the NHS was doing enough to protect identifiable data. They weren’t that keen on the gateway.
But I think we’ll get there. And my GP will get the information she needs. And maybe we’ll be able to do what's necessary to hold healthcare expenditure at a level which won't impact on our capacity to repair our roads and educate our kids.
While still providing adequate levels of care.
