This document discusses health informatics and compares it to medical informatics. Health informatics is a broader field that includes medical informatics as well as other areas like healthcare delivery, management, telemedicine, and patient education. Medical informatics focuses specifically on optimizing the storage, retrieval, and management of biomedical information. The document provides examples of areas within health informatics, such as electronic patient records, telemedicine, distance education, and how technologies in these areas can provide advantages like time savings and increased access to care.

2. Health Informatics The big picture Laeequz Zaman –Dr.

3. This Presentation What is health informatics? The difference between health Informatics and Medical Informatics The clinical analogy for Medical Informatics Variety of areas in Health Informatics The advantages of technology shift

4. Health Informatics Medical Informatics / Bio Informatics / Computer Medicine

5. Health Informatics The difference between health informatics and medical informatics is as much as the difference between the words health and medicine . Medicine is thus a subset of health with other subsets like health care delivery, health care management, telemedicine techniques, patient education, etc.

6. Therefore Health Informatics Medical Informatics is semantically different from, but often considered the same as

7. Medical Informatics "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." - Edward Shortliffe

8. The background French word informatique (mid 70’s) Processing the clinical information May be recognized as technological parallel to biological sequences A long list of advantages

9. The clinical scenario Cognition Action Presentation Recall Memory/ Knowledge Base Previous Observation(s) Teaching / Training Assessment Reasoning Action The patient presents

10. The MI analogy Second Opinion Telemedicine Retrieval Knowledge base Data Base Virtual Tutoring / Distance Edu. Assessment Artificial intelligence Machine integration The patient presents

11. The new to it… To many, it is merely the new way of doing the old things… To others, it is too advanced The realm of fact is not a debate of new or old… The paradigm shift is the set of gathered advantages!

12. Electronic Patient Records / Computerized Medical Records / Patient Archive Systems

13. EPR

14. Telemedicine

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.

16. Real-Time Synchronized The clinician can also …. View the patient on the screen Hear and talk, Access details of medical record,and Zoom in / zoom out of the images of lesions, etc. How are you feeling today, Mr. Patient Definitely better!! Thanks to your telemedicine !!

17. Advantages of Telemed Time saving Very cost effective Increases breadth of clientele Greater clinical variety of cases Distances have no meanings Support to clinical research Case study: World Care

18. Home Based Clinical Care Ease of use, Cost effectiveness, Timely decision making, Life saving

19. As in Fetal Monitoring in high risk mothers, for early diagnosis and alarming 24 x 7 VC monitoring of elderly, bed ridden patients and disabled persons Post Operative home care Biometric Signal monitoring of cardiac patients

20. Specialized Software Artificial Intelligence, Rule Based Systems, Reporting Systems, Research Solutions

21. As in Neural Network AI applications for clinical and operational decision making Rule based Decision Support Systems for clinical and operational management Specialized solutions for research management activities Performance indicator applications for individuals and departments

22. Cyber Medicine Email and WWW based HealthCare support

23. As in Question answer sessions for common diseases Web based, often store and forward, primary or second opinions Well known - Web MD, Medline and TeleMedPak Articles of general interest on the WWW Can cost more, unless financially superior to conventional healthcare services

24. Distance Medical / Health Education For students and general population

25. As in Virtual Medical University – US Virtual Hospital – US Virtual Medical Library – WHO EMRO Various Patient Web e-groups – Thalassemia Society Various Health Information Dissemination initiatives – NHS Net Countless email based list-serves

26. Future trends Not too distant

27. Future trends HIS towards artificial intelligence DSS Neural Networks Mobile health care support Tele surgery through movement sensitive equipment Direct biomedical signals’ transfer Reverse telemedicine

28. Thanks
