Computer-aided instruction
• These include computer-aided instruction, learning about computers and their applications, use of computer-based information resources, use of computers as a tool and as a mechanism for information management, decision support and communication.) While medical informatics includes computer applications, it is not limited only to the use of computers, but includes the knowledge, skills and attitudes involved in seeking, manipulating and using biomedical information.
Dr.T.V.Rao MD 18

Computer and Medical informatics
• Changes in health care delivery and styles of learning in medical education have forced a need to use and critically evaluate a variety of new teaching tools, including the computer. While the computer is unlikely to ever replace the patient as the primary focus of learning, it does have the ability to reproduce a highly interactive environment and can mimic many situations in Medicine.
Dr.T.V.Rao MD 19

Earlier attempts of teaching with Computers
• The first serious introduction of computers into medical education was made two decades ago. De Dombal reported the use of computer-based material to enhance the understanding of trainees faced in an emergency department with the management of patients with acute abdominal pain.
Dr.T.V.Rao MD 20

Are too slow adopting the change
• Medical schools have long recognized the need to revise their teaching methodology, but have been slow to change.
Dr.T.V.Rao MD 21

Patient data is most important source of information
• As medical knowledge continues to expand rapidly with demands for more efficient coordination of patient data become paramount, and the pressures for improved practice and application of evidence based medicine increases, medical informatics will have increasing influence in our working lives as clinicians.
Dr.T.V.Rao MD 22

We still continue to do with traditional Didactic methods
• Till recently, teachers and their pupils have been content with, and able to rely on, the traditional resources that have always been available in medical education. • This involves teaching and learning centred on the patient, and backed up by lectures and tutorials. Other information can be obtained from and journals. For a number of reasons these resources are no longer sufficient
Dr.T.V.Rao MD 23

Medical Education is shifting to Problem based learning
• There has been a philosophical shift in medical education in recent years. • Pioneered by the McMaster and Newcastle medical schools, there has been a move from the traditional lecturefocussed program to a problem-based approach (Harden).
Dr.T.V.Rao MD 24

Virtual reality in Teaching a priority in Medical Education
• The use of virtual reality in simulated procedures is a new application of computers in medical education and is as yet in its infancy. Procedures can be standardised and trainees able to test and practice their skills.
Dr.T.V.Rao MD 25

• Theory of Information Communications Coding Algorithms Probabilities and Stochastic Processes • Theory of Control Operations Research Optimization Management Science • Systems Analysis
Dr.T.V.Rao MD 26

Library resources becomes Electronic
• The modern library places an increasing amount of its material in electronic format and increasing numbers of journals are available either on CD- -ROM or over the Internet. This represents a considerable saving in storage space and manpower. Many students who wish to pursue their studies using library facilities can now do son in electronic fashion, and often from their own home
Dr.T.V.Rao MD 27

Faculty should be provide electronic information
• Faculty must identify the prerequisite information and skills that students need to enable them to access electronic information sources, as well as the course content the student needs to "know" and the information the student needs to "know how to access" electronically.
Dr.T.V.Rao MD 28

Students should develop interest in electronic information
• Students' attitudes toward their education may also have to change. Students need to learn that they must be information seekers as well as information managers. They also need to acquire knowledge about relevant sources of information, and the skills to access electronic information.
Dr.T.V.Rao MD 29

Handheld Applications
• ePocrates • 5 Minute Clinical Consult • Medical Calculators • Immunization schedule
Dr.T.V.Rao MD 30

Medical informatics Empower Students
• Helping students to become independent learners, information seekers, and proficient users of computer technology have long been goals that were often inadequately implemented throughout the medical school curriculum.
Dr.T.V.Rao MD 31

Orientation by teachers is the primary goal
• By making our primary goal the preparation of students to be medical information managers, we have a strong rationale for the inclusion of medical informatics applications into the curriculum. This goal also provides a criterion by which the appropriateness of curricular offerings can be judged and the outcomes of instruction can be evaluated.
Dr.T.V.Rao MD 32

Indian Journal of Medical Informatics (IJMI)
• Indian Journal of Medical Informatics (IJMI) is an Open Access, peer-reviewed, online journal adopting a broad definition of "medical informatics" and focusing on the applied aspects of computers to healthcare delivery.
Dr.T.V.Rao MD 33

Information Technology Basics of Security - 1
• make sure workstation is physically safe and

secure never send passwords by email • never paste passwords beside the workstation • install and regularly (weekly) update virus protection • avoid sending attachments • never open unsolicited attachments, always check an double-check the attachment’s file extension
Dr.T.V.Rao MD 34

Information Technology Basics of Security -2
• Never open unexpected file with extensions EXE COM DOC DLL PIF LNK VBS (Windows does not show LNK and PIF extensions) • Never click on a link – hover the link with mouse and look at the status bar where the link leads when clicked • firewall may protect both yourself and the world but may also cheat you)

Medical informatics makes education Interesting

Dr.T.V.Rao MD


Computer are staying with us..
• The computer is here to stay in one form or another. It is unlikely that any amount to scientific data on its reliability or validity will influence use of the medium. However, used appropriately computers can be of considerable educational benefit and will serve medical students and practitioners throughout their careers
Dr.T.V.Rao MD 48

Information technology is not a remedy for all ills in Medical Education
• Information technology must not be viewed as a potential cure to the current ailments of medical education. It may be part of the solution and should be treated as such
