The problems with Healthcare

For the past couple of years I have been educating myself on the problems of Information Systems in the healthcare industry and watching and analysing the Federal Government’s My Health Record initiative. It used to be called the PCEHR and I’ve commented on it before (see the category) I have also become Chair of the Health Committee of the Australian Continue reading The problems with Healthcare

The disconnect between business and IT

Happy New Year. I’ve just spent six months at a small Federal Government agency and, as usual have learned a lot about why IT fails to deliver value to the business. The IT department believes that all it takes is for them to gather requirements, design and build infrastructure and IT systems and its business users will be happy. Unfortunately, Continue reading The disconnect between business and IT

Health Information should be about decision making.

What is health information needed for? IMHO health information is only needed in order to make decisions. A health professional will be primarily interested in the current status of a patient and secondly, in the way in which the patient’s status is changing. Any other information is irrelevant and, potentially, confusing. Health information systems need to be designed and managed Continue reading Health Information should be about decision making.

Why Electronic Health Records can be a Bad Thing

My observation of the healthcare system is that the intention is to make things better for a patient. That means knowing two things: the current status and what to do next. The problem for the healthcare professional is getting the right data for a diagnosis – especially when diagnostic tests are expensive. The only reason that the medical history is Continue reading Why Electronic Health Records can be a Bad Thing

Knowledge and Understanding vs Follow a Recipe

I’ve been learning to bake bread. I’ve baked bread before, both with a machine and by hand. I can also turn my hand to cooking, although I wouldn’t claim to be an expert. I wanted to bake better bread and make a wider variety of loaves so I got a few books and started following recipes. That’s when things started Continue reading Knowledge and Understanding vs Follow a Recipe

Can you cost justify Architecture

There is a discussion on Linked In “You can’t Cost Justify Architecture!!! Can you?” “According to Zachman, cost of Architecture should not be scrutinised. It is not an expense but an asset that help in bringing Alignment, integration, change and mass customisation. As an Architect agree with statement but with a business hat on will I agree to that? Probably Continue reading Can you cost justify Architecture

Well formed problems: all problems are questions, not all questions are problems

I was listening to a talk on radio yesterday and someone was asking questions of the form “how do we make sure that entitlements go to the needy?” This is a question, but it does not define a problem. A well formed problem has: A goal Questions that must be answered in order to achieve that goal The goal is Continue reading Well formed problems: all problems are questions, not all questions are problems

More on the Elephant in the Model

One of the most important and critical nonlinearity in modelling is decision making. A big problem with making a decision is that you lose information – i.e. why you made the decision. e.g you need to work out what to do next. You look at various options but decide to take the “do nothing” option. Once you’ve made that decision Continue reading More on the Elephant in the Model

Nonlinearity – The Elephant in the Model and What the Elephant can Tell Us – again

After panicking to get my submission in by 15 February I got another IEEE email saying the final date for submissions is 25 February. So I did a bit more research to find if there is much on the subject of error growth in nonlinear dynamic systems in general. There’s not a lot. So I amended my paper, but discovered Continue reading Nonlinearity – The Elephant in the Model and What the Elephant can Tell Us – again

Nonlinearity – The Elephant in the Model and What the Elephant can Tell Us

On 11 February 2014, I received an IEEE call for papers for UKSim2014, the 16th International Conference on Mathematical/Analytical Modelling and Computer Simulation. Submissions were due on or by 15 February. Conference website: http://uksim2014.info In a mad panic I started to write a paper on nonlinearity, a topic that I think does not receive enough attention from the modelling community.
