Health Informatics - The Big Picture

  1. 2. Health Informatics The big picture Laeequz Zaman –Dr.
  2. 3. This Presentation <ul><li>What is health informatics? </li></ul><ul><li>The difference between health Informatics and Medical Informatics </li></ul><ul><li>The clinical analogy for Medical Informatics </li></ul><ul><li>Variety of areas in Health Informatics </li></ul><ul><li>The advantages of technology shift </li></ul>
  3. 4. Health Informatics Medical Informatics / Bio Informatics / Computer Medicine
  4. 5. Health Informatics <ul><li>The difference between health informatics and medical informatics is as much as the difference between the words health and medicine . </li></ul><ul><li>Medicine is thus a subset of health with other subsets like health care delivery, health care management, telemedicine techniques, patient education, etc. </li></ul>
  5. 6. Therefore <ul><li>Health Informatics </li></ul><ul><li>Medical Informatics </li></ul>is semantically different from, but often considered the same as
  6. 7. Medical Informatics <ul><li>&quot;Medical informatics is the rapidly developing scientific field that deals with resources , devices and formalized methods for optimizing the storage , retrieval and management of biomedical information for problem solving and decision making.&quot; - Edward Shortliffe </li></ul>
  7. 8. The background <ul><li>French word informatique (mid 70’s) </li></ul><ul><li>Processing the clinical information </li></ul><ul><li>May be recognized as technological parallel to biological sequences </li></ul><ul><li>A long list of advantages </li></ul>
  8. 9. The clinical scenario Cognition Action Presentation Recall Memory/ Knowledge Base Previous Observation(s) Teaching / Training Assessment Reasoning Action The patient presents
  9. 10. The MI analogy Second Opinion Telemedicine Retrieval Knowledge base Data Base Virtual Tutoring / Distance Edu. Assessment Artificial intelligence Machine integration The patient presents
  10. 11. The new to it… <ul><li>To many, it is merely the new way of doing the old things… </li></ul><ul><li>To others, it is too advanced </li></ul><ul><li>The realm of fact is not a debate of new or old… </li></ul><ul><li>The paradigm shift is the set of gathered advantages! </li></ul>
  11. 12. Electronic Patient Records / Computerized Medical Records / Patient Archive Systems
  12. 13. EPR
  13. 14. Telemedicine
  14. 15. This is how it works Physical Connectivity Channels : Telephone lines, ISDN, Fiber Optic Cables, Coaxial cables, etc. Virtual Channels : Satellite Transmission (radio waves), Terrestrial Transmission and reception (radio and infra red waves), etc.
  15. 16. Real-Time Synchronized <ul><li>The clinician can also …. </li></ul><ul><ul><li>View the patient on the screen </li></ul></ul><ul><ul><li>Hear and talk, </li></ul></ul><ul><ul><li>Access details of medical record,and </li></ul></ul><ul><ul><li>Zoom in / zoom out of the images of lesions, </li></ul></ul><ul><ul><li>etc. </li></ul></ul>How are you feeling today, Mr. Patient Definitely better!! Thanks to your telemedicine !!
  16. 17. Advantages of Telemed <ul><li>Time saving </li></ul><ul><li>Very cost effective </li></ul><ul><li>Increases breadth of clientele </li></ul><ul><li>Greater clinical variety of cases </li></ul><ul><li>Distances have no meanings </li></ul><ul><li>Support to clinical research </li></ul><ul><li>Case study: World Care </li></ul>
  17. 18. Home Based Clinical Care Ease of use, Cost effectiveness, Timely decision making, Life saving
  18. 19. As in <ul><li>Fetal Monitoring in high risk mothers, for early diagnosis and alarming </li></ul><ul><li>24 x 7 VC monitoring of elderly, bed ridden patients and disabled persons </li></ul><ul><li>Post Operative home care </li></ul><ul><li>Biometric Signal monitoring of cardiac patients </li></ul>
  19. 20. Specialized Software Artificial Intelligence, Rule Based Systems, Reporting Systems, Research Solutions
  20. 21. As in <ul><li>Neural Network AI applications for clinical and operational decision making </li></ul><ul><li>Rule based Decision Support Systems for clinical and operational management </li></ul><ul><li>Specialized solutions for research management activities </li></ul><ul><li>Performance indicator applications for individuals and departments </li></ul>
  21. 22. Cyber Medicine Email and WWW based HealthCare support
  22. 23. As in <ul><li>Question answer sessions for common diseases </li></ul><ul><li>Web based, often store and forward, primary or second opinions </li></ul><ul><li>Well known - Web MD, Medline and TeleMedPak </li></ul><ul><li>Articles of general interest on the WWW </li></ul><ul><li>Can cost more, unless financially superior to conventional healthcare services </li></ul>
  23. 24. Distance Medical / Health Education For students and general population
  24. 25. As in <ul><li>Virtual Medical University – US </li></ul><ul><li>Virtual Hospital – US </li></ul><ul><li>Virtual Medical Library – WHO EMRO </li></ul><ul><li>Various Patient Web e-groups – Thalassemia Society </li></ul><ul><li>Various Health Information Dissemination initiatives – NHS Net </li></ul><ul><li>Countless email based list-serves </li></ul>
  25. 26. Future trends Not too distant
  26. 27. Future trends <ul><li>HIS towards artificial intelligence </li></ul><ul><ul><li>DSS </li></ul></ul><ul><ul><li>Neural Networks </li></ul></ul><ul><li>Mobile health care support </li></ul><ul><li>Tele surgery through movement sensitive equipment </li></ul><ul><li>Direct biomedical signals’ transfer </li></ul><ul><li>Reverse telemedicine </li></ul>
