Introduction to Health Informatics



good evening and welcome to the first theoretical course or the introduction to health informatics in the United States and today would collectively be going through the totality of how health information systems and health informatics and the health information infrastructure in the United States is constructed okay now the first question I'm going to ask you is what is the health informatics and obviously by now if you're in this class you already cannot know what health informatics is and the certified electronic health specialist that certification is a subset of health informatics and it's utilization in the United States so according to Wikipedia health informatics can be divided into several categories the can be invited into medical informatics nursing informatics clinical informatics bioinformatics public health informatics healthcare analytics and so on and so forth and in a nutshell it deals is basically an intersection between health care computer systems data and the ability to manipulate data the ability to store data and the ability to analyze data right so that in a nutshell is what informatics says so we're basically talking about data it's interaction with computer systems and also the healthcare sector if you have a question at any time all you need to do is to click in the box or you know put your questions in the box and I'll be glad to answer them so what makes up the health information infrastructure in the United States and in this particular course this introductory cost without systematics we're going to discuss the health information infrastructure that has been constructed in the United States over the last 15 to 20 years okay so initially the health information infrastructure health informatics the infrastructure was only begun under the Bush administration and then the Obama administration came in and the Romulus so the big thing that the Bush administration did was to globalize or nationalized the concept of health information technology and it's applications in health care more specifically these applications in archiving medical records within a healthcare facility or within the healthcare planet okay and the second thing that they did was lay out a framework under which the whole country can be networked so to produce a slow a seamless flow of health information from one part of the country to another or from one facility to another so when I became the health information infrastructure in the United States a couple of names come out or you know striking as part of the component of the health information infrastructure in the United States and the first thing that strikes me well the first thing that comes to my mind is the National Health Information Network the National Health Information Network is basically an interoperability network and don't really bother if you don't understand all the terms I'm using this is actually a first class and by the middle of the class by the middle of the course you'll understand exactly what these terms do but for your knowledge basically the national or the nationwide health information network is a network that allows connectivity between one area of healthcare or another in one region of the country to another so basically it's more or less a situation whereby healthcare data or clinical data can be transported database to database across distances and of course for that to happen it means that they have to have the same standard right how many of you know the importance of maintaining a standard for the transport of information who can tell me the significance of why you would need a stand so a bin baller says the correct information passed between festivities that is correct but how do you ensure that the correct information is passed from one facility to another well let me ask this question this way how many of you are familiar with any medical standard at all just list the standard in the box okay that's a very good try Jennifer HIPAA is definitely a standard but it's not a data standard so how many of you have heard of icd-9 or icd-10 how many of you have heard of the CPT codes how many of you have heard of sno-med CT how many of you have heard of hl7 okay so these are all standards that will enable the transfer of information so let's say for instance there's a specific code let's say our icd-9 code a disease code you plug the disease code because the disease code references a specific disease you know if reference is specifically what the disease is so if you want to transfer that information from one area to another instead of going in and writing acute lymphoblastic anemia you might put in the icd-9 icd-10 code so that and that enables you to transfer information from one database to another okay so that's exactly what then by the time we get to the middle of this course you'll understand exactly what we're getting at all right so the National Health Information Network is basically is almost like a banking network and let's say for instance you are in Atlanta Georgia and you bank with Wachovia but you travel to Los Angeles in California and they don't have a lock over a bank in California can you withdraw your money from the bank yes or no yes you can if you have an ATM card you can walk to an ATM machine anywhere in the world and withdraw your money and the only reason why you can withdraw your money from any ATM machine in the country is because all the banks operate on the same standard so which means like when you put your ATM card into a Bank of America ATM machine in California and you say you want to withdraw money you're the Bank of America understands precisely because of the culture in the card that this card number one belongs to you no but she is associated with the pin that you put in number three belonging this is a la cobia Bank that is based in a specific place and number four can verify that you have money in the bank so if Bank of America and Wachovia decided to build their networks on different standards that would not be possible but because their networks have the same standard you can go to any country in the world that uses the regular ATM machine and put your card in the ATM machine and you'll be able to reach for some money and so is the healthcare network and that's the whole idea behind in healthcare the idea basically is you go to any part of the country and any doctor or any facility or any provider should be able to go into their system and pull up your information not because they have direct access to your doctor's records but because being on the same system put in the right authentication and when I say authentication I'm pretty much talking about the security access code that facility would mean and based on that they should be able to access your medical records so that's basically what you call interoperability and sometimes it's a difficult concept to understand but by the time you get to the middle of the course you totally understand exactly what it is okay so the national organ nationwide health information network is in national concept so regardless of the states you are in in the United States you are part of the National Health Information Network now the next stage is the regional health information network and let me just tell you one thing about health informatics or health education technology these things change on the dive so what I'm telling you now is probably gonna be all views by the end of the year and with the end of the year being December which is about three or four months away you understand how fast things change okay can you guys hear me now okay great so so basically the city of New York has a Regional Health Information Network the state of Connecticut has been I believe Colorado has one California has one and so on and so forth okay now the entity the entity which means the various stakeholders or the individual organizations that come together to form a regional health information organization I wouldn't call stakeholders in a regional health information organization any suggestions guys if you don't have any just say no okay I see somebody's typing I'd like to welcome you Kimberly and just for your information this lecture is being recorded so you can go back and listen to it a little later okay um so I'm asking again should I give you guys some clues who can name for me some health care establishments within your hair excuse me okay sorry about that I was knocked off the internet by a quick manner okay so we're worried okay we're talking about medical errors then avoiding the relative repeating medical tests and so on and so forth okay so the next thing out all the electronic health of the health information that was basically rich not about you before the advent of electronic health records this is the walk you would call paper records so they will take these paper charts and they will scan them as files into the electronic medical okay so that's basically what they would do with your previous history and some facilities go back as far as five years on some facilities go back as far as ten years we were talking about electronic health records as a longitudinal record of health so basically anything anytime you record patient demographics in any way shape or form in relation to their health care the forms an electronic health record so I know probably a little past time but we try and rush the rest of it okay now the electronic medical record is a little different from an electronic health record so basically an electronic medical record is an electronic health record because they constitute one of those applications where you record patient information however the electronic medical records more specifically is a provider application so this is an application that you get in a hospital or an ambulatory clinic so whenever you have a physician or healthcare worker entering information about a patient into some sort of database you recall that in the electronic medical record but any time any information health related information is recorded is recorded in an electronic calculator so in the electronic medical record is an electronic health record was an electronic health record you know necessarily an electronic medical record if you understand to say so the clue basically is the electronic medical record or EMR belongs to a specific organization you are also an electronic health record may not necessarily belong to one organization for example the nationwide health information network is an electronic health record but when you go to your doctor's office he records your information in an electronic medical record okay so that's all I'll pretty much say in regards to the electronic health record electronic medical record that this slide just basically clarifies screening you know what the differences are between the electronic health record and electronic medical record now another thing that you have to take cognizance on is that when you're talking about databases are following your EHR follows you that it contains a bunch of information that might not necessarily directly relates with you your electronic medical record is owned by your provider but it's archives are stores your information when you see them your personal health record also called the PHR is a true that you would use so the PHR belongs to you and it's to basically track your healthcare reference as well so theoretically your personal health record should be able to download all the information from every single encounter you have with the healthcare system and store a copy senior alright so the PHR can pretty much save money avoid inconvenience and old information that could be key to what you get improper accurate and cost effective care whenever you visit the healthcare provider because there are a lot of medical terms or medical situations where you as a lay person and that's with the presumption that we are a lay person might not necessarily remember about your health for example what will your blood levels of certain types you know hormones or oils or different things like that and even if you're a healthcare worker there are many details of your help I might not necessarily remember in detail so that pretty much is the function of what a personal health worker would you all right so next and I think we're about that into the end of the course and I think we're actually there these are your references all right so I'll go ahead and place both the slides and the video recording on the side the online classroom for you to access latest tomorrow are there any questions before we end the lecture for today so thank you very much for attending today's lecture and I wish you best of luck with your assignment okay now let's take a quick consensus before we go for today
