Health Informatics Series
Introduction to Health Informatics
Mark H. Spohr, MDHealth Care Informatics IER/HIS, World Health Organization, 20, Avenue Appia, CH-1211 Geneva 27 SWITZERLAND
Health Informatics Series: Health Informatics2 |
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
Health Informatics Series: Health Informatics3 |
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.
Health Informatics Series: Health Informatics4 |
Tools
Health informatics tools include not only computers but also clinical guidelines, formal medical terminologies, and information and communication systems.
Health Informatics Series: Health Informatics5 |
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

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.
Health Informatics Series: Health Informatics7 |
mHealth
Mobile Health
Mobile technologies such as mobile phones to collect and access health information.
Health Informatics Series: Health Informatics8 |
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.’
Health Informatics Series: Health Informatics9 |
Key Elements of Informatics
Acquisition
Storage
Communication
Manipulation
Display
Health Informatics Series: Health Informatics10 |
Health Information Systems Context
Health Informatics Series: Health Informatics11 |
Health Informatics Principles
Use drives data
Interoperability using open standards
Incremental development and strengthening of systems
Enterprise Architecture approach
Collaborative Communities
Health Informatics Series: Health Informatics12 |
Decisions Determine Data
Health Informatics Series: Health Informatics13 |
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
Health Informatics Series: Health Informatics14 |
Enterprise Architecture
Health Informatics Series: Health Informatics15 |
Encourage open systems
Health Informatics Series: Health Informatics16 |
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
