Building the Australian National Health Network

Dr George Margelis, from Intel's Digital Health Group, talked last night in Canberra on "The Patient Journey - What role for IT?" he will be repeating this in Brisbane 17 March.

Dr Margelis, showed a number of interesting before and after video segments of problems with the health system and how ICT could help. Normally I dislike company videos in presentations as they are advertisements for companies. While these were clearly produced for Intel, they were relevant to the topic.

The first video was of someone being rushed to hospital in an ambulance (which I could identify with having had it happen to me). This illustrated how currently medical staff in the ambulance and the hospital use computer based systems, but these are not linked, so that information has to be relayed by voice or paper. A future scenario showed the patent details being shared online between the ambulance and the hospital. Dr Margelis emphasised that none of the technology envisaged was exotic and was not already in use in other fields. It was a matter of integrating it into the medial system in a way which helped the medical staff and the patents.

The major issue was to network records so that dispersed medical services could serve the patient. Dr Margelis showed a scenario networking the ambulance to the hospital, to the remote specialist.

In a later scenario Dr Margelis showed patients using a home based system. This not only monitored the patent and prompted them to take medication, but also connected them to their helpers and medical staff, using a wireless mHealth device.

One problem I had with these scenarios is that they were applying computerisation to an existing system without considering how to change the system. As an example, it is difficult for a hospital to obtain patent's GP records in an emergency, because the records are stored on paper in dispersed GP offices. The Intel solution is to network the records. An alternative low technology solution would be to group the GPs in clinics. These clinics would then be large enough to employ professional record keepers and be open 24 hours a day, so they could respond to emergency record requests. My doctor would not like this as they see themselves as a provider of custom personal services, not part of a corporation. However, the alternative ICT solution will result in some loss of their autonomy.

What Dr Margelis presented was a clear logical vision. The question this raises is why has it not been done? This is not a technical issue, but still an issue for ICT professionals. It is not enough to we have a solution, it is the customer's fault for not buying it. The underlying issues as to why such systems are not implemented need to be addressed.

The Prime Minister has proposed to take over all public hospitals in Australia. As Dr Margelis pointed out, the public hospitals are the smallest and least important part of the health care system. There is a risk that the government will concentrate on hospitals, resulting in better hospitals but an overall decline in the quality of health care and an increase in costs. This would be similar to the situation where the government funded insulation in homes is likely to increase energy use, rather than reduce it. Similarly a networked national hospital system may increase costs and reduce the health of the population.

Some far less glamorous, less expensive, more local community health initiatives, might be far more effective. These could still make use of ICT.

The NBN Company provides one possible model for the health care reforms. Under this approach the government announced an impressive sounding multi-billion dollar national broadband network (NBN). They then set up a government owned company to implement it. What NBN Co has done is architect a national system, but are first implementing small scale local projects. These projects are small enough to be implemented efficiently and provide local benefits in the short term, so the government can be seen to be delivering services (in what might happen to be marginal electorates). One day all these system might join up into the envisaged national system, but in the interim they will provide useful local services to the community and political kudos to the government.

Current attempts at national e-Health standards are mired in the need to have a consultative process between government and industry. NBN overcame this problem with broadband standards by consulting with parties, but making clear that as a company they were not required to wait for everyone to agree and were going to make a decision and then implement that decision. A NHN Co (Australian National Health Network Company) could make similar decisions for e-health standards and the implement them.

The government could announce the goal that all public hospitals would be networked and all patent electronic health records would be available by a set date. Governments and companies which did not wish to cooperate would not be funded.

One interesting question asked was when will patents will be able to ask their doctor to put their records on Google health. This might be useful for the patent, but the doctor would need to be compensated for the extra effort in working out how to do this.

Another question was on casemix to provide appropriate incentives for keeping people healthy, instead of dispensing medicine to them. If there were the right incentives this would provide an incentive for better ICT systems to keep the patents out of hospital.

It was pointed out that there are now international standards for medical imaging (Xrays). There is now under way for standards for the medial records delivered to the patent in the home, so that we will not first build proprietary systems and then have to convert to real standards. It may be that Australia has to accept an international standard which is not as good as a local standard, but which is adequate and has the advantage of widespread acceptance.

Changes Needed to PBS prescription forms

PBS prescription formToday I went to the chemist to have a prescription filled. The Pharmacist told me they could not do so as I had presented only the duplicate copy of the prescription. They told me this was a common problem with many customers only bringing in half the form. The PBS prescription forms are supplied by Medicare Australia, and there appear to me to be several flaws in the design of the form. This is not simply an inconvenience as the result is that the patient does not get required medicine, thus placing their health at risk.

What I took to be two separate prescriptions joined by perforations are in fact an original and a duplicate. Unfortunately this is not made clear on the form. There is a section of the form marked with a light cross hatching pattern which faintly spells out "Pharmacists patent COPY" sideways. Apart from being almost illegible, the original and duplicate are in the wrong order. The copy is o the left, when it should be on the right, as English is written from left to right, an original should come first. Also if old fashioned carbon paper was used, the copy would be underneath and therefore second in a pile of papers).

Medicare needs to redesign this form to make it usable. An interim workaround would be to instruct doctors (and their software suppliers) to print an appropriate message on the form.

Cordless drill used for brain surgery

As reported by the ABC and other media, Dr Rob Carson used a DeWalt cordless drill to a hole in the skull of a 12-year-old boy top relieve bleeding to the brain in Maryborough, Victoria.While obviously an emergency measure, cordless tools would seem to be a good choice for this as they would reduce the risk of electrocution. From the photos shown in the media, the unit used appears to be a DEWALT DC759KA 18-Volt Ni-Cad 1/2-Inch Cordless Drill.

Display Screens for Medical Imaging

Browsing through the diminishing collection of paper magazine at the University of Canberra library on the weekend I came accross an article on the use of LCD screens for displaying medical images. This goes by the acronym PACS (picture archiving and communication systems). It is used to manage digitised old fashioned X-rays, as well as ultrasound, magnetic resonance and computed tomography. Having been subject to all these procedures recently, I found it of interest.

Because of the risk of missing something on an x-ray, there are specially made and calibrated (and therefore expensive) LCD screens. One interesting way to quickly check a monitor is to display text in subtly varying colours and ask the user to type it in. There is open source medical imaging software available.

Dealing with Swine Flu pandemic using smart phones and podcasting

Australian government agencies are advising of Swine Flu Precautions. In 2006 I presented "E-government for emergencies: dealing with a bird flu pandemic using the wireless web and podcasting" at CeBIT Australia (extended technical presentation, ANU, 26 March 2007). This discussed how wireless web technology and podcasting could be used for dealing with a possible influenza pandemic. This included providing advice to the public and to officials on what to do, using the technology to manage health resources. Students in the ANU course "Networked Information Systems" COMP2410 learnt how to design web pages for this and many of them now work in and for government agencies.

One problem at the time was, and remains, that there is no unified web based service in Australia. Each state health authority issues its own information in its own format. While this made sense when the information was issued in the form of brochures the public might pick up at their local library it makes little sense online, where the state governments are just as accessible as each other.

The Internet can also be used to keep services operating, including government, with fewer staff and where gathering of people is not possible.

Online status of hospital Emergency Departments

The WA Department of Health is providing a near real time web display of the status of Emergency Departments. This shows: Ambulance diverted, Triage 4 patients average waiting time (minutes), Number of patients waiting to be seen in ED and Total patients in ED for each hospital. Also available Hospital beds are also shown (but from a few days ago). If this information is to be of use, it must be provided reliably. Reports over time are also offered, but when I tried "ED attendances weekly activity" an error message resulted: "There is no row at position 7. at System.Data.RBTree`1.GetNodeByIndex(Int32 userIndex) ...".

Clinical Information System Request for Comment

The ACT Government has issued a request for comment for a draft "Clinical Information System: Intensive Care Unit" for Canberra hospitals. Having had recent first had experience of being in the system and attended a talk on ICT in Health Delivery in the 21st Century I found this of interest. One aspect of the requirements is the use of a web interface:
Functionality unique to the ICU environment (representing well over 80% of clinical care delivered in the ICU):
• Real time interfacing to unique bedside devices and equipment
• Flow-sheet and decision support assisting clinical decision making using unique parameters with unique clinical interrelationships
• ICU specific medication management with a superset of medications prescribed in a unique environment
• Maintain the patient’s medical record for the duration of their ICU stay in accordance with legislated requirements for record keeping and contribute to the centralised hospital clinical record.
• Retain records of all interactions and interventions applied to the patient.
• Manage the large volume of data obtained from the regular and frequent downloads from monitors and ventilators, with the ability to drill down to the smallest time interval captured from each device
• Assist in the reduction of errors associated with patient records relating to legibility and calculations.
• Assist in the reduction of errors associated with the prescribing and administration of medication.
• ICU specific terminology for clinical notes and pathways tightly integrated to the decision module
• Have the ability to take information stored about one intervention or modality and populate it through related clinical flowcharts / forms
• Assist in the medical/nursing care of the patient by facilitating the tracking and recording of medical/nursing tasks.
• Remove the need for unnecessary duplication or reproduction of patient data
• Provide query and reporting capabilities including standard and ad hoc reports to meet the requirements of - Commonwealth, Territory, Facility, ICU, Research, ANZICS, ANZPIC
• Provide ad hoc and standardised reporting functionality for quality improvement activities and improved clinical management
• Provide the ability to perform timely audits including the provision of a clear audit trail.

Functionality provided by interfacing with other Clinical Systems:
• PAS (ACTPAS at TCH, and IBA at Calvary)
o Obtaining Patient Identifier and Demographic information, to do the following:
• Patient registration
• Patient admission and discharge
o Episodic Information
• Patient bed movement within and outside the ICU, for example, whilst in
Radiology
• RIS/PACS
o Viewing of medical images / reports
• Pathology Information System
o Importing a subset of available atomic pathology results, to allow intelligent decision rules to be used, for example, low potassium level and alert would flag the user to this situation and suggest a predefined course of action; and the viewing of all pathology results and medical imaging reports via a web-browser interface
• CRIS
o Export of data to centralised TCH Clinical record
• Future Scope
o Ordering of diagnostic imaging and pathology requests
o Pharmacy (Medication and Infusion Management).
o Provide Pharmacy electronic ordering and bar-coding capability.
o System to integrate with Clinical Portal application
o All environments to be integrated into one environment
The solution should be suitable for use in an acute clinical environment by providing the following general features:
• Easily navigable
• Facilitating the recording of clinical data in a structured (e.g. selection from reference table, numeric), and unstructured (free text) format.
• Intuitive (e.g. requiring minimal training for use).
• Presentation of patient data in clear and informative manner.
• Easily and extensively configurable ...

Health Informatics Conference 2009 Call for Papers

Peter Croll, Chair of the Health Informatics Conference 2009 (HIC 09), visited today to talk about the conference. Rather than have an event on the rather dull topic of computerising old fashioned medical records, next years will look at new models of health care delivery and how ICT can support them.

call for papers

Dear Colleagues

The Health Informatics Society of Australia (HISA) invites the submission of papers, panels and workshops for the 2009 Health Informatics Conference (HIC'09) to be held in August, 2009 in Canberra, at the Canberra Convention Centre Healthcare brings together both practitioners and information technologists in unique partnerships that fuel rapid advacements in the delivery of care. In this field of constant discovery, healthcare's use of information and communication technology continually expands the limits of the domain and has led to stunning innovations and intensely practical outcomes.

"Frontiers of Health Informatics - Redefining Healthcare" seeks to capture this diversity of achievement in linking science and medicine with information technology. Importantly, it looks at the practical systems and process issues that need to be addressed now, to meet the challenges of the future. HIC'09 is built around four key information technology themes that are driving change and innovation in Australian healthcare. Each theme looks to analyse the leading edge technologies that are being implemented and the opportunities they create. The HIC09 themes are:

  • Personalised medicine and bioinformatics
  • Next generation electronic health records
  • Innovative healthcare environments
  • Preventative Healthcare and Fitness
  • This conference highlights the multidisciplinary nature of health informatics and provides a unique opportunity to bring together the finest minds from the health care, academia, industry and non-profit organisations. It aims to forge new industry collaborations and identify potential avenues of research and development across all models of healthcare and human diseases.

    This is a truly exciting time for health informatics.

    See you in Canberra in August 2009!

    Virtual Machine Infrastructure for NZ Hospitals

    The New Zeeland West Coast District Health Board has issued a request for proposal for a Virtual Machine Infrastructure to replace its current 41 are physical servers. This is an interesting example of an attempt to rationalise a complex computer system. The board will need to decide if its two server rooms (primary and backup) are sufficient and how if more than just two physical servers are needed. The board would need to balance the saving in hardware and energy (and lower greenhouse gas emissions) this would provide against the security are reliability issues.

    Health Informatics 2009 Conference Meeting, 9 Dec, ANU, Canberra

    Peter Croll, Chair of the Health Informatics Conference 2009 (HIC 09), will be in Canberra Tuesday and Wednesday. I was asked to help put him in touch with people at the Australian national University people to discuss participation and keynote speakers. Peter will be visiting me at my ANU office, Tuesday morning, 9
    December 2008, should others in Canberra with an interest in health informatics wish to join us. Alternatively you may wish to contact Peter directly. Last year's conference, HIC08 was in Melbourne. The draft program for this year is appended.

    I don't know much about Health Informatics, but occasionally review
    papers for the electronic Journal of Health Informatics. I now have a personal interest, as I ended up an emergency patient in Canberra Hospital a few weeks ago. ;-)

    Here is the text of the description of the conference I was sent:
    HIC09 Conference Description

    Healthcare is a deeply personal and often intensely compelling endeavour, driving practitioners and technologists to ceaselessly explore for improvements in the delivery of care. Its use of information and communication technology often sits at the current limits of the domain.

    Canberra Health System First hand Experience

    Last week I attended a talk on ICT in Health Delivery in the 21st Century by Ian Bull from ACT Health. Less than forty eight hours later I was experiencing that system first hand having been taken by ambulance to Canberra Hospital. This is a brief note to thank those involved with my treatment, reassure all that I am reasonably well and describe the experience for others.

    At about 11:30 am on Thursday 13 November I started to feel unwell. I was due to attend a second video conference with ACS Green ICT in the Canberra CBD . However, as I bent down to unlock my bicycle to ride it to the video conference room I felt dizzy. I relocked the bicycle and walked back to my office at ANU. Some time later I was found by the Department of Computer Science staff in an incoherent state and an ambulance was called.

    After treatment on site, the staff helped move me down to the ground floor to the ambulance. This was a slightly undignified exit as, due to the small size of the lift, it was easier to have me sit on my office chair and be pushed along backwards. I helped propel myself with one foot, but had to be told to stop doing this when we got into the lift.

    The ambulance ride was surprisingly uncomfortable: I seemed to feel every small bump in the road and my dizziness made every corner seem very sharp. During this time I could hear the staff communicating by two way radio with the Canberra Hospital emergency department. I was given an aspirin to thin my blood (it tasted like lemon, which worried me until I was told it was lemon flavoured aspirin).

    At the hospital I was checked by a triage nurse just inside the door and within what seemed less than a minute pushed through to the intensive care section of the causality department. I was helped from the stretcher to a bed in a small one bed room.

    At this point numerous people when through a well rehearsed routine asking me questions, reporting to each other what was known, recording details. My body was covered with what appeared to be dozens of sticky electrodes for an ECG (the staff apologising that the electrodes already attached in the ambulance where not compatible with the hospital system). After a time I was hooked up to a machine which beeped annoyingly and left for what seemed a few minutes.

    I must have dozed off and when I awoke it was late in the afternoon and I felt completely better. It was a little embarrassing to find myself awake, apparently completely well and occupying what was clearly a very expensive medical facility. I was reassured that was okay as they needed to assess me (my first inclination was to get up and walk out).

    For the next twelve hours I would be asked repeatedly my name, date of birth and if I knew where I was. This was annoying, but I realised after a time it was to check if I was mentally okay. Before being allowed to stand up I first had my blood pressure checked sitting and standing. Then I was asked to close my eyes and move my limbs various ways to check I had balance. Several times I had all joints tapped with a rubber hammer and reflexes noted, poked with a blunt pin to check for sensitivity, had my eyes checked for responses.

    Fully conscious, I seemed to be the least unwell person in any of the sixteen or so beds (which were occupied most of the time). I even seemed to be healthier than some of the staff. My bed faced the nursing station in the centre of the room (arranged so the staff there could observer every bed. What first got my attention was that there were two large computer screens which they consulted over ever now and then.

    There was a confusing array of different uniforms worn. I was asked if I had been seen by a doctor and realised I had no idea which were the doctors (almost everyone had a stethoscope). The general rule seemed to be that the more uniform-like the clothing worn, the lower status of the staff, with the consultant doctors on the top of the pecking order having no uniform.

    Everyone there seemed to know what to do except me. However, just when I question would occur to me, such as "do I get something to eat?", someone would appear and ask if I was hungry. Some aspects seemed less organised. Several times someone would say something was going to happen, then leave, someone else would then come in and ask what was happening, whereupon I would explain I was being sent for some treatment. At one point I had difficulty convincing a nurse (by this point I had worked out the people in bright red tops were the emergency nurses) that I had just had my blood taken and there was no need to do it again. Most of this questioning was genuine, but I suspect some was to check on my mental state without the tedium of asking where I was again.

    After a few hours, a couple of visitors, and some phone calls to reassure people I was okay, the novelty started to wear off. While I was in a room of my own I could still hear the discussions around me and of the same questions I had been asked being asked to new arrivals. There were also cries of pain and coughing indicating people in a far worse state than my own. Feeling completely well, it was frustrating to be tethered to a bed by heart rate and blood pressure monitors. I had to be unplugged by someone each time I wanted to get up.

    Having a
    Computed tomography (CT) scan turned out to be a much less scary experience than I was expecting. Laid on a motorised bed, my head was moved into a doughnut shaped device. This was like like putting your head into a large front loading washing machine (I could see part of the mechanism rotating trough a transparent window).

    The ultrasound scan of my neck turned out to be less pleasant than I expected. This was used on my neck to check blood flow. The device is pressed on and an image displays on screen, with blood flow in colour. At the same time there is the sound of the blood flowing (something like a special effect from a low budget science fiction movie). The device had to be pressed uncomfortably, but not painfully, hard to my neck to get a clear image.

    What was surprising was the speed with which tests were done. I expected to be moved to another building or at least another floor, but was instead quickly whisked around a corner, tested and then back again. One disconcerting part was the TV show in the imaging waiting area, which had advertisements for life insurance, will kits and funeral funds. I was well enough to see the humour in this, but it might might be disturbing for someone less well. Another unusual sight was the ceiling of the imaging area covered with black fingermarks, while every other surface was antiseptically clean. The staff explained that this marks were left by the electricians changing cabling.

    Several times the staff would collect around the large computer screen with one operating a keyboard to scroll through a list, presumably reviewing the status of each patient. During one of these sessions, someone in a slightly scruffy suit (looking like the forensic pathologist out of an Inspector Morse episode) glanced over at me said something like "he looks well enough". I was then whisked out of the room and two beds down to a curtained area, it being explained that the room was needed for a suspected infectious patient. The next person to check my blood pressure looked a little confused as the chart for that bed said I was eleven months old.

    As I had attended a talk on the
    $165M project to produce integrated e-health standards for Australia, I took a particular interest in the computer systems used. Apart from the large screen used to manage patents there was a lot of ICT evident. Several of the staff were equipped with walkie talkies.

    One quick change the hospital could make would be to turn on the power saving features of the large screen displays at the nursing station. These display a screen saver message after a few minutes which wastes power and is annoying to look at. The station has two displays side by side facing opposite directions. Due to the need for cooling, there was a sign on the back saying not to place notices there. This wastes a large area of the most important part of the room. A notice board could be bolted to the back of the display, leaving sufficient space for cooling. I noticed one doctor using the LCD screen as a lightbox, to examine x-rays. Perhaps the software needs a function which, at the push of a button, displays a blank white screen for this purpose.

    The blood pressure and heart monitors were computer operated (it was disconcerting to have my arm constricted by an automatic blood pressure cuff every hour). But the various systems were standalone. While the devices at the end of the bed would record a sequence of readings from me over time, someone came with a paper chart to transcribe the readings.

    The CT and ultrasound machines are computer controlled and produce digital images within a few minutes, but the output is turned into x-ray like transparency photographs which took an hour or so to get to the doctor (presumably this would be quicker or an urgent case).

    My details had to be re-entered into each computerised device and checked. From the time I was first seen by the paramedic, my details were verbally relayed by radio, telephone, paper and face-to-face between numerous staff. ACT Health are to spend about $300M integrating these systems over the next few years (the ultrasound operator was looking forward to a new film less system arriving shortly). Apart from reducing the risk of errors, linking the systems up will reduce the cost of the processes and allow the staff to spend more time on the patients. However, linking up these systems reliably is a major undertaking.

    While using the computerised equipment the staff also understood its limitations. Rather than just look at the machines, they would first look at the patent and see how they looked. This became comical at times, such as when the most important consultant was examining me but the pulse monitor was in the way. After some hesitation he unclipped it, then realised that it would sound an alarm within a few seconds if there was no pulse recorded. He handed it to his assistant who wondered what to do with it (considering handing it to the next person down in the pecking order). The consultant suggested he clip it to his own finger so the system would get a reading, but I suggested this would not be a good idea as the record of my heart rate recorded would suddenly change which might confuse someone checking readings later.

    After about twelve hours in the hospital I was told I could go home. This was somewhat of a surprising anti-climax. I was handed a copy of a letter sent to my GP, with instructions on when to come back for an Magnetic resonance imaging (MRI) scan and what medicine to take and not to drive a car for a month (riding a bicycle is okay for some reason). There were no forms to sign and no mention of money (the cost of the treatment must have been significant).

    Within a few minutes I was out the door. It was a bit difficult finding my way out as I had not walked in and I had never seen the outside of the building. I called a taxi and returned to the university where the last session of the Green ICT Symposium 2008, I had organised was taking place. As I entered I was greeted by a round of applause by the audience, who had obviously been told of my illness. This was heartening. I stayed for lunch with them and then went home to rest.

    My thanks to the staff of the Department of Computer Science at ANU for coming to my aid, the ACT Ambulance Service and the Canberra Hospital. Also thanks to Senator Lundy, who chaired the symposium in my absence.

    ps: Some might like to carry out a word analysis in postings to this blog, before and after 11:30am last Thursday, to see if I have recovered. ;-)

    NZ e-Health System

    The NZ Ministry of Health has issued a Request for Proposal for a " Identity Data Service Solution" for identification of patients and doctors. The RFP includes a detailed 117 page document detailing the information needed in the system and standards to be used. The requirement appears very similar to the $165M project for e-health standards in Australia. However, there appears to be no mention of the Australian work in the NZ tender. It would seem sensible for Australian and NZ to use compatible e-health systems.

    Open Source for Australian e-Health

    Ian Bull from ACT Health delivered an excellent talk on ICT in Health Delivery in the 21st Century at the ACS Canberra meeting, 11 November. The state and federal health authorities have been working on a $165M project over the last three years to produce integrated e-health standards for Australia. I suggest this work be expanded with an additional $50M to produce open source software implementing these standards.

    Ian discussed the work of the
    National EHealth Transition Authority (NEHTA) and intermeshed with state health authorities, including the ACT. This is a complex project involving data standrads, changes to medical business processes and issues of access to health data accross state boarders. While a high risk project, it has large potential benefits for improved health and savings in health care costs.

    One interesting aspect is that this project avoided being mired in the failed health and social services access card project of the previous federal government. There are no plans to issue a standard health card as part of the project, although this would be done for identifying doctors and other health workers.

    The techncial standards being developed are available free online for use by Australian medical system developers. However, I suggest that the project could go further and develop open source software implementing the standards. This could be used to prove operation of the standrads, to aid Australian software developers in implementation, to help developing nations with implementing e-health systems and to boost the Australian e-health export industry.

    The Australian medical software industry is fragmented with very many small companies producing software packages for doctors and other health professionals. Producing software to interface to the new national standards will be a large burden for this firms. Instead, the government (Medicare Australia in particular) could fund development of open source software which would proud a proof of concept of the new standards. The companies could then incorporate this software in their systems to produce commercial packages. As well as providing for the domestic market, this could create an export industry in e-health. Exports could concentrate on new markets in developing nations using new technologies, such as mobile phones to replace doctor's computers.

    ICT in 21st Century Health Delivery

    Ian Bull will be talking on ICT in Health Delivery in the 21st Century at the ACS Canberra meeting 11 November:

    The role of ICT in the delivery of health initiatives has come to the front with both the Federal and ACT governments have announced new strategies particularly in health and patient records and the concerns about security and privacy.
    Ian will provide an overview of key National activity and explain the role of the National EHealth Transition Authority (NEHTA) and how ACT Health initiatives link to the national activities.
    Ian Bull has been working in Health involved in Information Management and a variety of Health ICT implementations for both Public and Private Organisations for over 20 years. His present role is with ACT Health is concerned with the coordination of National EHealth Initiatives being progressed through the National EHealth Transition Authority (NEHTA) and their links to ACT Health ICT Initiatives.

    Cradle Coast Campus a model for flexible learning

    The University of Tasmania's (UTas) new Cradle Coast Campus at Burnie might provide a useful model for flexible learning for secondary and tertiary institutions in Australia. The facilities, including a wellness centre are housed in the one building, with computer equipped open plan areas, cafe and library, as well as more formal study areas. It is a shame the building was not avialable when I gave a talk in Burnie last year.

    ps: Of course, a cynic might say that the "wellness centre" was a way to get around the former federal government's ban on student union facilities. ;-)

    Home Made Soda Water

    Soda Club Fountain Jet Soda Maker, Starter PackageThe doctor told me to give up carbonated drinks some months ago. The problem is not the carbonation, but the sugar in flavoured drinks and the salt in mineral water. Soda water seemed a safer option, but it is hard to tell if it has more salt than tap water. The supermarket had a Sodastream drink maker on special, to make soda water from ordinary tap water, so I got one of those. This will not save much money but should save hundreds of plastic bottles and their transport to the supermarket.

    The Sodastream, also called a Soda Club soda maker in the USA, has a gas cylinder good for 40 to 110 liters of soda water (depending on which brochure you read). When the cylinder is empty you exchange it for a full one (unlike soda siphons which use disposable gas cartridges). The unit comes with a clear plastic one liter bottle, which looks like a regular disposable drink bottle but has much thicker walls. You fill the bottle with tap water (cool or very cold, depending on which instructions you read) and screw the bottle into the device. Pressing a button on to releases CO2 into the water with a loud rush. After a few presses a release valve makes a flatulent noise, indicating the bottle. You then unscrew the bottle, add any flavoring wanted and put the cap on.

    There do not seem to be as many bubbles as with store bought soda water, but it is okay (formal academic research has been published on optimizing the bubble size and carbonation with the Sodastream). One worry is how much the CO2 gas refills will cost. According to the Soda Club web site the refills cost US$19.99 plus shipping in the USA (they are available in Australia from supermarket counters). At that rate the soda water is comparable in cost to that bought in the supermarket (about 60 cents a litre).

    Soda Club, Twin Pack BottlesThe soda makers are sold online by Amazon.com, but at US$99 are more than twice the price in an Australian supermarket. Replacement plastic bottles are about US$10 for two online and $AU$15 in the supermarket. This is expensive for an empty plastic bottle, but they can be used over and over again. The bottles have an expiration date on them, the one with the unit was dated October 2010, giving it about a two year lifetime. Assuming I made one bottle of soda water a day, the bottles will cost about 1 cent each.

    Obviously it would be better if I gave up fizzy water and drank ordinary tap water, but I like fizzy water. Assuming the device lasts, it should save hundreds of plastic PET bottles a year, plus the enviornmental cost of them being transported to the supermarket. Each liter of water weighs a kilogram and it is a lot more efficient to transport water by pipes than in bottles in a truck.

    There is an amazing number of patents for gadgets to make water fizzy. The patent for the Sodastream device is cited as a precedent in intellectual property law.
