 Okay, thanks Kate. Hi everyone. I'm from Health Director Australia so I'll start by talking a bit about Health Director Australia, about who we are. We're a government funded organisation we're not the profit, we're actually a co-ag company. We've been going since 2006 and we're actually owned by the federal health department and the state departments, state health departments of every state except for Victoria and Queensland. We were set up to develop a range of digital health and telehealth services. We began as the National Health Call Centre Network for people to contact after hours if they're having trouble with any health issues. We became a digital organisation maybe five or six years ago and we provide digital services and other health information and advice to the Australian population. Some of our websites and services are the main Health Direct website which is a general health website. We also have the pregnancy birth and baby website. We have a carer gateway for those people who identify themselves as carers of people who have a disability or who are chronically ill. We run the Health Direct After Hours GP helpline to another contact centre, the My Age Care website on behalf of the federal government. We have a National Health Services Directory so you can find the GP's specialist emergency departments in your local area. We run the quit line and get healthy services in New South Wales as well. I'm here to talk about the Australian Health Thesaurus which we manage. It's a Thesaurus of medical, health and human services related to concepts. It's human services as well because we manage the age care and carer websites. It reflects the current Australian health and human services environments. You can see on the right hand side, we have over 5,000 concepts within our Thesaurus. It was originally developed by the Department of Health and Aging many years ago and we inherited that Thesaurus about 4 or 5 years ago. The Thesaurus is actually based on Mesh, the medical subject headings which is maintained by the US Library of Medicine. We regularly update the Thesaurus. We look at all the user analytics to see what are people searching for on our website. We look at the current news developments such as the Zika virus. When the outbreak occurred in Australia a couple of years ago, we had no concepts on Zika virus so we added that in. We also do environmental analysis of certain domain areas such as age care which we did when we set up the MyAgeCare website. We looked at all the websites in Australia that focus on age care and looked at all the concepts that they're using. The main thing about our Thesaurus though is that it's consumer focused. It's not aimed at the clinicians or health professionals. It's aimed at consumers. We try to keep that focus on the concepts. This slide here is on the left hand side. This is the main concept schemes within Thesaurus. You can see we've got anatomy, chemicals and drugs, diseases and disorders, equipment and supplies, facilities. There's quite a lot of different concepts there. If you click on one of those concept schemes, you can go through the hierarchy to see and on the right hand side you can see I've gone down through diseases and disorders, digestive system diseases and I've now selected the liver cancer concept. Clicking on the concept provides the shows us the other information about that concept and here you can see what is called the SCOS view, the SKOS, the Simple Knowledge Organization System view which is basically showing you the broader, narrower and related concepts. Also on the right hand side you can see we have the preferred label and alternative labels and the alternative labels are the synonyms. The idea being for our websites that if people, in this case, if they search for hepatic cancer, they can find content that has been classified with the concept liver cancer. The main reasons we have Thesaurus is, as I've just mentioned, was the classification purposes. All that content is classified with Thesaurus. It also helps in the relevance of our search results in the ranking. We also use it for auto-suggestion as well so once you start typing in your search in the top field you'll get a list of suggestions to select. We can display other contextual content on the website as well such as a video on asthma will appear on content, an article about asthma because they're both classified with the same concepts. And we also use it to manage our medicines data and this is what I really want to show you today because it shows you how we are linking our data. We've set up a medicines catalogue and we've looked at all the publicly available medicine data sets that we could find in Australia and we're starting off with our own Australian Health Thesaurus which we are using as our control list. We've also looked at the Australian medicines terminology. This is the national standard for naming conventions for all medicines in Australia. This is managed by the Australian Digital Health Agency authority. We also have data from the Therapeutic Goods Administration through the Australian Register of Therapeutic Goods. That's a register of all the drugs that are sold in Australia. They also have data from the Pharmaceutical Benefit Scheme and also Guild Link which is the commercial arm of the Pharmacy Guild of Australia and from then we get pill images and we're just going through a process with them at the moment to get their consumer medicine information leaflets. That's the leaflet that's in a packet when you buy it over the counter and we want to get that in HTML format so that we can present the data on our website in a much more consumer-friendly way. We're also getting data from Drug Bank which is a great Canadian government initiative. It's got great information about medicines and chemicals. You can see on this side now that this is what we do with Thesaurus. This is how we start the linking process with these other data sets. I've selected the concept Amitriptiline which is an active ingredient and we've created a whole new concept custom schema which we call clinical relationships and you can see on the right-hand side in that column you can see we have added the ID, the identification of the Australian Medicines terminology ID and a bit further down we've also got an ID for Drug Bank so it's just a mapping with those concepts in those data sets. You also see there's a reference there to a BEAS criteria and that's not the fact that this can be used to make BEA. It's an internationally recognised list of medicines that are inappropriate to prescribe to older people. In this case this is one of those drugs and we've got the Boolean logic of it true here. A bit further down we've also got a pregnancy category as well which we get from the TGA and this has got a pregnancy category of C. We're not actually using that at the moment but we do intend to use that on our website soon. So what we're doing every month we update what we call a terminology service. It's a database. We import all the data from all of those those data sets into our terminology service from the Australian Health Asaurus, the TGA, PBS, the AMT, Drug Bank and the Guildlink and we've developed the relationships between all those data sets so that when a user searches for a medicine on our website they can dynamically pull that content all that data into a web page for them. On this page you can actually see how those relationships work. I showed you where the AHT had that reference to the Australian Medicine terminology and Drug Bank. We can see that those relationships are here with the Drug Bank and AMT. The AMT actually has seven different data sets within it. From medicinal product which is a list of could be the active ingredient used in a drug and the trade product which is actual brand name of that. And you can see you can actually work your way through these relationships to come down to the container trade product pack which could be in that data set. It could be a Panadol 20 milligrams, 20 tablets in a blister pack and that data set has a reference to the Australian Register of Therapeutic Goods ID which the TGA manages. And Guildlink also uses that ID as well. And you see on the other side, left hand side there, the PBS link which is there's a reference to that ID in the medicinal product unit of use data set. So we can link up all of these data sets. And as I said before the use is that so that if somebody searched on any medicine we can pull the data from all of these data sets to show information to the people. And so what does it look like to a user? I can show you from our side here. This is a page on the drug endep. And as I scroll down the page you can see there's the information on the page. Remember when I said the beers criteria? Because I had that true flag in the data, we've pulled up this warning here to say that if you're over 65 years of age there may be specific risks and recommendations for use for this medicine. So please consult your health professional or pharmacist. As I scroll down here people can select the type of packet that they have. In this case whether it's a 10 milligram or a 25 milligram or a 50 milligram pack that's coming from the AMT, the strain medicines terminology. One of the bits of data we have from the TGA is a PDF version of the consumer medicines information leaflet and so we have a link to that. So if that exists then they can click on this read leaflet to be able to read the consumer medicines information leaflet which will tell them all about the side effects of the drug when they can use it, when they can't use it that type of thing. Then we have other information here as well coming from the TGA and also images coming from Guildlink. So we've got the dosage form, the route of administration, we've got information about the pack, about how to store the drug and the lifetime of the drug. And also if that drug was available on the PBS then there's a link here as well to go to the PBS site. Okay go back to the slide. The thesaurus can also be used, we have a public version of it that can be accessed by individuals and organizations as well. So it can be used for research purposes. Just remember it has its consumer language. It's aligned to medical, clinical and government standards and systems and it forms a bridge between those three different domains. And it can be used for the surveys, for interviews and for transcripts and I've got the link for it coming up soon. But this is what the public version of thesaurus looks like here. You can do a search for a concept. You can select the A to Z list or you can click on any of the concepts and just drill your way down through the concepts to find the right concept you need and you can still find the right information. This is only showing that SCOS view that I showed you before with the broader narrower and related concepts but you can also find some other information on that as well. And there's also a visual version of it as well so that you can see in a visual format what are the the narrower and related and broader concepts of that that concept. Here are some some links which you might find useful. The first one is of our website, the main health threat website. We also have a link there to the medicines pages where you can start searching and see the how all that data comes together. I've got a link here which shows you general information about the thesaurus and for those actually want to get into the thesaurus and look at it itself. That's the link down the bottom. That's the thesaurus.healthdirect.org.au slash A-H-T. Okay and that's it so thank you.
