- Simplistic definition: Computer applications in medical care, medical education and medical research Medical informatics is the rapidly developing scientific field that deals with the use of computers and communication technology to acquire, store, analyze, communicate and display medical information and knowledge to facilitate understanding and improve the accuracy, timeliness and reliability of decision-making.
- It combines medical science with several technologies and disciplines in the information and computer sciences and provides methodologies by which these can contribute to better use of the medical knowledge base and ultimately to better medical care.
- We will start by trying to understand why this field of study is called medical informatics. Medical informatics began in the 1950s with the advent of computers. During this time scientist intuitively realized that they could create medical applications of computer science. They however did not know what they should call this field of study. They initially named it medical computer science but after a while the term computer science became a concern to many scientists. Computer science in the 1950s was not as defined at it is today. In the 1950s it mainly dealt with hardware, and specifically making hardware smaller and faster. They knew that this field of study that they were trying to create encompasses more than just hardware. They wanted a term that described the fact that it encompasses the use, processing, analyzing and storage of information. They thus changed the name to medical information science. The term information science not only encompassed the aspects of computer science, but all fields associated with storage, processing, analysis and commutation of information e.g. Mathematics, library science, information systems, communication technology etc. After a while the validity of this domain name again began to be questioned, specifically the use of the word medical. This term did not explicitly indicate the other types of data was associated with this domain. This domain name did not include the biological data associates with the field like genome sequences, proteins, amino acids and bases etc. they therefore started using the term Biomedical computing. However after a while this term was also very limiting. They realized that this field of study also encompasses all of the associated medical data like demographics, information needed by health manager for resource allocation, HR data etc. They then called this domain medical informatics. This is probably the most common title, but in Europe health or health care informatics is used and in America clinical informatics is used. These three terms mean the same thing.
- In 1949, Gustav Wager established the first professionally organization for medical informatics in Germany. The first medical informatics application were in dental projects in 1950 by the unites states national bureau of standards. In the mid 50s expert systems like MYCIN were developed and used. In 1965 the national library of medicine stared using Medline. In 1968 homer Warner, who is one of the fathers of medical informatics, founded the department of medical informatics at the university of Utah. In 1970 the international medical informatics association was founded. In the same year the MUMPS language and operating system was developed and used for clinical applications.
- MI is basically the collection, storage, analysis, dissemination of medical information by the means of computer and information technology so that quality care can be provided to the patient
- Why do we require standardisation? excessive diversity creates inefficiencies or impedes effectiveness. Standardisation is required to allow interoperability btw independent system, so tht the information collected of a patient by one system can be used by another. There are four ways in which a standard can be produced: 1. Ad hoc method: A group of interested people and organizations (for example, laboratorysystem and hospital-system vendors) agree on a standard specification. These specifications are informal and are accepted as standards through mutual agreement of the participating groups. An example produced by this method is the American College of Radiology/National Electrical Manufacturers Association (ACR/NEMA) DICOM standard for medical imaging. 2. De facto method: A single vendor controls a large enough portion of the market to make its product the market standard. An example is Microsoft’s Windows. 3. Government-mandate method: A government agency, such as the Health-Care Financing Administration (HCFA) or the National Institute for Standards and Technology (NIST) creates a standard and legislates its use. An example is HCFA’s UB92 insurance-claim form. 4. Consensus method: A group of volunteers representing interested parties work in an open process to create a standard. Most health-care standards are produced by this method. An example is the Health Level 7 (HL7) standard for clinical-data interchange.
- ISO estb in 1947 International Organization for Standardization Comité Européen de Normalisation Health Level Seven American National Standards Institute Also IEEE, DICOM, W3C, NCPDP, NCCLS etc
- TC 251 Established by european committee of standardisation in 1991, to develop standards for communication among independent medical information systems so that clinical and management data produced by one system can be transmitted to another system. Groups are working together at various levels toward a common goal. Standards of interest include EUCLIDES, for interfacing reference laboratory systems to health-care settings, EDIFACT, for transmission of electronic documents, and a message standard developed by Project Team 007 (PT007) for transmitting content of electrocardiogram (ECG) carts to computers 1998, the International Standards Organization (ISO) created a new technical committee (TC 215) for medical informatics. The scope of this TC is standardization in the field of information for health and health information and communications technology to achieve compatibility and interoperability between independent systems.
- Medical Informatics emphasizes information brokerage; the sharing of a variety of information back and forth between people and healthcare entities. Examples of medical information that needs to be shared: lab results, x-ray results, vaccination status, medication allergy status, consultant’s notes and hospital discharge summaries. Medical Informatics harnesses the power of information technology to expedite the transfer and analysis of data, leading to improved efficiencies and knowledge.
- Uses of Medical Informatics : Informatics Use in Health Care can be in the following fields: 1) Communication : This includes Telemedicine, Tele-radiology, Patient e-mail and Presentations 2) Knowledge management : Including Journals, Consumer Health information and Evidence-based medical information 3) Decision Support : Including Reminder systems, Diagnostic Expert Systems and Drug Interaction 4) Information Management : Examples are Electronic Medical Records, Billing transactions and Ordering Systems
- Telehealth: refers to clinical and non clinical services such as medical education, administration and research Telemedicine: refers only to the provision of clinical services Teleradiology: ability to send radiographic images from one location to another location Telecardiology: ECG etc can be transmitted using telephone and wireless Telepsychiatry: allows anonymity of patient and less social stigma, physical examinations are not important Correctional health: telehealth for prisoners in correctional health facilities Teledentistry: use of IT and telcommunications for dental care, consultation, educational, and public awareness
- Reduced visits to hospitals and reduced congestion in hospitals Store and forward: involves acquiring medical data like medical images and then transmitting this data to a medical doctor or specialists at a convenient time for assessment offline Remote monitoring: also known as self monitoring/testing, enables medical professionals to monitor a patient remotely using various technological devices Interactive telemedicine: provide real time interactions between patient and provider, to include phone conversations and online communications
- - Official journal of the International medical informatics association and the European federation of medical informatics Indian assoc of medical informatics This app provides access to an online health community, where patients can connect with and learn from other patients experiencing similar health issues. It offers a members-only discussion forum, as well as medical news and information from the Mayo Clinic. VaxNation, an online vaccination tracker. You enter information such as your birth date, vaccinations that you've had, and the dates of those immunizations, and VaxNation provides age-appropriate recommendations, Families can set up joint accounts, and accounts can be linked to Facebook and Twitter so that information about immunizations can be shared
- Although all medicine based on science has some degree of empirical support, EBM goes further, classifying evidence by its epistemologic strength and requiring that only the strongest types like from meta analysis, systematic reviews and RCTs can yield strong recommendations, weaker types such as case control studies can yield only weak recommendations Gold standard of clinical practice Index Medicus (IM) was a comprehensive bibliographic index of scientific journalarticles focusing on medical science fields, published from 1879 to 2004. It was initiated by John Shaw Billings, head of the Library of the Surgeon General's Office, United States Army. This library later evolved into the United States National Library of Medicine (NLM). In the 1960s, the NLM began computerizing the indexing work by creating MEDLARS, a bibliographic database, which became MEDLINE. Index Medicus thus became the print presentation of the MEDLINE database's content, which users accessed usually by visiting a library which subscribed to Index Medicus Contains 21.6 million records from5639 selected publications First use the term evidence based in 1988 in his workshops to teach specialty societies how to use formal methods to design guidelines. He laid out the principles upon which the first evidence based guidelines would be formulated, it was for ACS guidelines for cancer screening, first published the term in 1990 in an article in the JAMA
- At its core is the collection of Cochrane Reviews, a database of systematic reviews and meta-analyses which summarize and interpret the results of medical research. The Cochrane Library aims to make the results of well-conducted controlled trials readily available and is a key resource in evidence-based medicine. Scottish doctor noted for his book Effectiveness and Efficiency: Random Reflections on Health Services.[1] This book advocated for the use of randomized control trials to make medicine more effective and efficient.[2] His advocacy of randomized controlled trials eventually led to the development of the Cochrane Library database of systematic reviews, COCHRANE REVIEWS-The Cochrane Database of Systematic Reviews DARE- Contains quality-assessed abstracts of systematic reviews, including a summary of the review and a critical appraisal of its overall quality CENTRAL- Is a database that contains details of articles of Controlled trials CMR- Is a bibliography of publications that report on methods used in the conduct of controlled trials. HTA- Brings together details of completed and ongoing health technology assessments NHS EED- This database systematically identifies economic evaluations from around the world, appraises their quality, and highlights their relative strengths and weaknesses
- Medical decision support- computer based information processing to help decision makers Medical decision making- quantitative methods for reasoning under uncertainty SMS is popular and most widely welcomed mode of reminder, strong consistent evidence that mobile text message reminders improved rate of attendance compared with no reminders, SMS is also private in a way that voice calling is often not It improves drug dosing, improve preventive care but not diagnosis
- “EMR is a repository of information regarding the health of a subject of care in computer-processable form that is able to be stored and transmitted securely, and is accessible by multiple authorized users. nodal authority that will be responsible for development of an Integrated Health Information System (including Telemedicine and mHealth) in India, while collaborating with all the stakeholders, Formulation of policies, strategies and implementation plan, Formulation and management of all health informatics standards for India; Laying down data management, privacy & security policies, standards and guidelines, promote setting up of state health records repositories, To deal with privacy and confidentiality aspects of Electronic Health Records (EHR). National Centre for Disease Informatics and Research- they maintain a national research database CCDC- Centre for Chronic Disease Control,Detection and Management of Coronary Heart Disease patients (DEMAT) in India. This is a nationwide disease registry for acute coronary syndromes in India. The DEMAT program was designed in year 2006 with an objective to understand the prevailing practice patterns in the management of Coronary Heart Disease patients. It also envisions to help physicians identify in-hospital trends of interventional procedures
- Medical Informatics and Information Technology is important to multiple players in the field of Medicine. The common goals of these different groups are to: • Reduce medical errors and resultant litigation • Provide better return on investment (ROI) • Improve communication and continuity among the key players • Improve the quality of care • Reduce duplication of tests or prescriptions ordered • Improve patient outcomes, like morbidity and mortality • Standardize care among clinicians, organizations and regions • Improve clinician productivity • Speed up access to care and administrative transactions • Protect privacy and ensure security Clinicians - Doctorspring, medeanta(telemedicine)
- Database creation to study populations, genetics and disease states Online collaborative web sites e.g. CaBIG Electronic case report forms (eCRFs) Software for statistical analysis of data e.g. SPSS Literature searches with multiple search engines Randomization using software programs Improved subject recruitment using EHRs and e-mail Online submission of grants
- P. L. Rogers (2000) identifies similar barriers based on the literature and two studies she conducted: availability and quality of hardware and software, faculty role models, funding, institutional support, models for using technology in instruction, staff development, student learning, teacher attitudes, technical support, and time to learn to use technology. However, she organizes these barriers differently. Some barriers have an internal source, such as a teacher’s attitude or perception about a technology as well as his or her competency with that technology. External barriers include: availability and accessibility of hardware and software, technical and institutional support, and stakeholder development. Time and funding barriers cross internal and external sources.
- • First challenge: We have to prepare physicians for the changing behaviours of patients who are increasingly internet savvy and who sometimes appear to know more about their diseases than their doctors • Second challenge: closely linked to the first, is to raise awareness among physician and medical students in training of many benefits of using ICT to improve not only the qualities of interventions and health care delivery but, from a broader perspective, the organizations of health care system itself • Third challenge: is to motivate medical students and practitioners to use ICT to find information, learn and develop, e-literacy should be a mandatory skill for all medical students • Fourth challenge: how to implement this innovation into teaching and learning
- Increase in use of technology- more data generated Mobility of population- need to communicate Specialization- need to communicate Managed care systems- need to communicate Rise in healthcare costs- attempt to control care Improved hardware- faster and more memory Improved methods- acquisition, transfer and retrieval Reduced computer costs Increased awareness
