What is Medical Informatics?

Health Informatics

Healthcare Informatics

Biomedical Informatics

Definition

• “The scientific field that deals with biomedical information, data, and knowledge—their storage, retrieval, and optimal use for problem-solving and decision-making.” Shortliffe et. al.

Component Sciences

• Computer Science

• Decision Science

• Cognitive Science

• Information Science

• Management Science

• Health Science

Questions and Concerns of Health Professionals

• Will computers replace physicians, nurses, pharmacists and other health professionals?

• Should they be highly trained in computer science also to practice their profession?

• Are we moving towards robotic medicine?

Nature of Medical Informatics

• It is an experimental science• Basic research questions• Applications research• Some consensus that the core discipline is

identical• Unified medical informatics educational

programs • Brings together students from a wide

variety of applications interests

Specialized Hardware and Programming Languages?

• In general medical informatics applications use existing computer hardware

• A specialized programming language called MUMPS was developed in the early seventies for medical records processing

• The software requirements of medicine (healthcare) do not seem to be unique

Relationship to Biomedical Engineering

• Biomedical Engineering focuses on Instrumentation– Advanced monitoring systems– Imaging devices like ultra sound, CT scans,

MRI devices etc.

• Medical Informatics emphasizes– Medical information and knowledge– Information and knowledge management

using computers

Nature of Medical Information

• Clinical information differs from that of Physics, Chemistry or Engineering

• Medical information incorporates uncertainty
