Regular readers of the blog will wonder why I should be concerned by this claim of such huge net benefits. The reason is very simple. While I firmly believe there are major benefits to be harvested from the deployment and use of e-health – and I believe the literature makes it reasonably clear where they are to be found – such claims are simply unsupportable without very substantial additional evidence.
NEHTA talks of the model they have developed in the following terms:
Modelling approach used for the study
• System Dynamics Model:
- Increasingly preferred (e.g. NHS)
- 900+ variables, 300+ calculation nodes, 25 sectors
• National and international expertise engaged:
- Jurisdiction, consumer and clinician input
• Focuses on major e-health benefits, costs and relationship to demand, quality and safety as e-health initiatives are rolled out over a 10 year period
Additionally they cite a range of published evidence from CITL, RAND etc and claim that from 3400 papers published since 1980 that Adverse Drug Events can be reduced by 50% (or more) by using Computerised Physician Order Entry (CPOE) with effective interactive decision support – among a range of other benefits that have been identified for e-Health.
They also suggest that there are 500,000 years of life to be saved in the Australian Population over 10 years with the implementation of e-Health.
What is conspicuously absent from all the presentations is the ‘how’? We are not told any of the basics that are required to make this credible. Obvious questions are:
What is the strategy, transition and implementation plan to move from where we are now to this 10 year future nirvana? If you don’t have that properly understood, documented and agreed with stakeholders how can you make any sensible comments about possible benefits? This is serious cart before the horse material I believe!
What are the assumptions for the capabilities of the systems to be used in hospitals and ambulatory practice to achieve these benefits? (It should be noted CPOE is notoriously difficult and complex to implement in hospitals – to the extent that – when last I looked – no more than 5% of hospitals globally have such systems in place. They are also not cheap to buy and implement.)
How much will such systems cost and who is going to pay for them?
What is a realistic time frame for replacement of present systems with the new more capable systems assuming they are readily available?
Given the vast majority of patient care is delivered in the private sector just what incentives (from Government) will be required to get the private sector on board?
Do we have the doctors, nurses and pharmacists who are sufficiently well trained and skilled in IT to make the transition to the e-health way of doing things?
Who is going to capably manage and co-ordinate such a huge change management and technology implementation program?
Are the assumptions in the model regarding a Shared EHR strategy correct? Is that ultimately the right approach for Australia? There is certainly a case for a careful review of the options being deployed around the world.
So what do we have here? Essentially what we have is a model without a strategy for architecture, implementation, funding and subsequent benefits management. There is no point putting out a generic claim about a possible scale of benefits without laser like clarity on just what is being proposed – or the economic hard heads in Treasury will shoot you down before you get started. This is where my concern lies. We have a once in a generation chance to propose a major re-investment in e-health for Australia and for it to succeed we need a model of an implementable and stakeholder approved strategy and implementation approach. Without clear and totally credible answers to all the questions I pose above, this initiative will turn out to be an expensive waste of time and effort.
It is vital in all this that those managing this proposed implementation ‘under promise’ and ‘over deliver’. I see no evidence of that approach in all this.
It is all very well for the Financial Review to publish an exciting headline and it is always important not to let the facts get in the way of a good story but I really think a little more digging regarding the reliability of NEHTA’s numbers, the assumptions and risks involved, the underlying strategic assumptions and recognition that things are usually much more complicated than they appear in a proposed, and largely yet to be defined, project of this scale would have been useful.
I look forward to NEHTA’s release of the Strategy and Implementation Plan that the model assesses along with the model and its assumptions. I will not be surprised to find I am once again disappointed and that sadly it all turns out to be largely ‘smoke and mirrors’ which will get us nowhere.
A final point that should be made is that the NEHTA Benefits Case relies on the deployment of clinical decision support (CDS). That, CDS, is sadly not actually part of NEHTA’s work plan as currently published. If it is actually worth so much, focus is needed and fast! Whoops!
We will wait and see!David.
