  1. Health Informatics Series Introduction to Health Informatics Mark H. Spohr, MD Health Care Informatics IER/HIS, World Health Organization, 20, Avenue Appia, CH-1211 Geneva 27 SWITZERLAND

  2. Why Health Informatics? • Health Informatics provides information to make decisions • Better information leads to better decisions • Health care, management, planning and policy all need good information

  3. Health Informatics • The intersection of information science, computer science, and health care. • It deals with the resources, devices and methods required to optimize the acquisition, storage, retrieval and use of information in health.

  4. Tools • Health informatics tools include not only computers but also clinical guidelines, formal medical terminologies, and information and communication systems.

  5. CDC Health Informatics • CDC's National Center for Public Health Informatics (NCPHI) provides leadership in the application of information and computer science and technology to public health practice, research, and learning. • Electronic health record support of public health functions • Use of health care, population and other public health data in supporting public health systems and analyses • Basic capabilities that support public health practice such as statistical and health surveillance • Public Health decision support

  6. eHealth • eHealth is a broad term for healthcare practice which is supported by electronic processes and communication. • The term can encompass a range of services that are at the edge of medicine/healthcare and information technology.

  7. mHealth • Mobile Health • Mobile technologies such as mobile phones to collect and access health information.

  8. Informatics ≠ IT • Information Technology is not Informatics • Information technology is hardware & software. • IT is to nouns, as informatics is to verbs. • Informatics helps IT ‘work appropriately.’

  9. Key Elements of Informatics • Acquisition • Storage • Communication • Manipulation • Display

  10. Health Information Systems Context

  11. Health Informatics Principles • Use drives data • Interoperability using open standards • Incremental development and strengthening of systems • Enterprise Architecture approach • Collaborative Communities

  12. Decisions Determine Data

  13. Incremental strengthening of systems • You always have legacy systems • The goal should not be to implement a single system but to encourage the development of interoperable systems. • If it works, enhance it! • Much easier to make continuous small improvements than to re-design and re-implement the entire system • Enterprise Architecture Approach

  14. Enterprise Architecture

  15. Encourage open systems

  16. Make vs. Buy… Or Modify • Buy Software • May not be an exact fit to your needs • Build Software • Long expensive process not guaranteed to succeed. • Modify • Start with open source software that you can modify • Modified software to meet your exact requirements • Everyone benefits from your investment in the software

  17. Collaborative communities of practice

  18. Health Informatics Series • Mark H. Spohr, MD • email: mhspohr@gmail.com • Lectures in this series: • Introduction to Health Informatics • Enterprise Architecture • Interoperability • National Health Information Systems • Patient Identifiers • Software Selection
