Define Medical Informatics
Medical informatics is a scientific/systematic
field of study that deals with the acquiring, storage,
retrieval, and processing of medical, biological and associated data,
information and knowledge for the purpose of problem solving and
decision making
Data, Information, Knowledge
Data are the raw facts obtained
Information is outcome of analyzing data
Knowledge is obtained from analyzing information

Why Medical Informatics
Why is proper management of medical data important ?
• Patient health record
• Administrative purposes
• Research and knowledge discovery
• Legal issues
• And the list goes
Why Medical Informatics
What is lacking in the current approach ?
• Organizational
• Logistical
• Research
• Passive nature of paper

Why Medical Informatics
What is lacking in the current paper based approach ?
Medication errors:
• Patient has allergic reactions
• Wrong medication given to patient
• Wrong dosage given to patient

Why Medical Informatics
What is lacking in the current paper based approach ?
Cost:
• Paper and storage• Environmental Cost
Time:
• Find record, perform tests

Video Five
Ultimate goal is to improve the quality of health care, research and education
in medicine and health
Public Health
Aggregated clinical data can be analyzed to identify emerging diseases within a region, country, or around the world.
Public health alerts (e.g., new flu strain) can
be incorporated into clinical information systems used by primary care clinicians.
Personalized Medicine
Genomic medicine
Manage greater quantities of data and more complex data over time
Does it Always Work
No
Steps to Success
According to Haux: Patient centered recording and use of data Process integrated decision support Comprehensive use of patient data for clinical and
reporting
Change ManagementWorkflow analysis Simple technology (Health care in the information society. A prognosis for the year 2013 -- Haux R, et al. Int J Med Inf 2002
