Lecture 1 Flashcards
Data
Characters,numbers, or facts gathered for analysis and possibly later action
Information
Interpreted data, I.e B/P readings
Knowledge
Synthesis of information from several sources to produce a single concept
Wisdom
Occurs when knowledge is used appropriately to manage and solve problems
Open or closed systems?
Health It systems are open systems
Informatics
It is the art and science of turning data into information
Imaging informatics
How images are acquired and processed,before they are retrieved,analyzed and distributed across an electronic medical record system.
Nursing informatics
Clinical informatics-analyze and manage patient data, primarily for the purpose of individual patient care.
Pharmacy informatics
Medication related data and how that data applies to patient care and outcomes. It has particular importance in terms of medication management and patient safety.
Public health informatics
Tracking disease outbreak,managing the spread of illnesses, analyzing immunization data and studying the results of new treatment protocols.
Health information management
Patient data focus and summarize the data,enhance the quality of data
Health informatics again
Is a mix of health science,information management/IT, Ana’s management science
Information literacy
The ability to recognize when information is needed as well as the skills to find, evaluate, and use needed information effectively
CIO
Head of information technology
End-user
Patient or employee
Vendors and software developers
Vendors are huge players and often sell their software and services
Policy makers
Government and professions like OMA,RNAO
Back office staff
Examples are programmers,analysts,engineers,webmasters,DBA and persons responsible for security and compliance with regulations
Best in Klas
It is an award given to vendors software that was the best in its category
Superusers/Champion
Provide patient care or related services
Show interest in “computer stuff” and expertise in the use of computers and information systems.
Serve as a resource in the work area
Input devices
Allow the user to submit data into the computer (ex. A keyboard or a mouse)
Central processing unit (CPU)
The “brain” of the computer also called the chip or processor.
Main factor in computer speed and capability
2 major manufacturers intel and AMD
Speed is measured in GHz
Central processing unit (CPU main parts)
Arithmetic logic units-executes numeric instructions
Control unit-manages instructions to other parts of the computer
Registers
Primary memory
Is the main memory (ex.RAM) once the computer is turned off if the file is not saved the document is gone.
Secondary memory
External devices like hard disk drive
Read-only memory (always present)
Secondary storage
Secondary storage retains data after the computer is turned off or in a medium separate from the computer
Output devices
Allow the user to view and possibly hear processed data
Peripheral hardware
Any piece of hardware connected to a computer (ex.mouse or keyboard)
Networks
Combination of hardware and software that allows communication and electronic transfer of information between computers
Types of networks
Thin client technology-system processing occurs on the server with minimal hardware requirements at the local level
VPN
Ergonomics
The interaction between people and their environment (human factors)
Software
Instructions directing the work of computers
Operating systems
Manage all computer activists
Application software
Designed to accomplish a particular task (ex Microsoft word)
Utility programs
Help to manage the computer and it’s data
