  1. Computers in the Ambulatory Care Setting Chapter 11

  2. The Computer System BASIC SYSTEM: • Input Device: keyboard, mouse • CPU: brain of the system • Software: required by computer to accomplish tasks • Output Device: monitor, printer, fax

  3. Types of Computer Systems • Supercomputers: fastest, most powerful and most expensive. • Mainframe: next largest in size and processing ability, used for large volumes of repetitive calculations. • Minicomputers: handle large amount of processing • Microcomputers: • Most widely used, Personal computer (PC)

  4. Components of a Computer System • Data Storage Devices: • Read-only Memory (ROM): permanently writes data or instructions into the memory • Random access memory (RAM): erases or “lost” when the computer is turned off (temporary storage data).

  5. Components of a Computer System • Data Storage Devices • Hard Drive: non-portable storage device • Floppy drives: • portable memory storage device • Zip drives and Jaz drives • Hold 100 and 2,000 megabytes of data • Optical disks • Servers

  6. Components of a Computer System • Networking: electronic connection of one or more computers, printers, software, and databases for the purpose of sharing information and resources. • LAN – local area network; most likely found in ambulatory care setting. • WAN – wide area network; usually found in a hospital-type clinic with many computers and sites.

  7. Software Applications • Frequently referred to as a computer program, can be thought of as a set of instructions to follow or data to process. • System software: operating system that tells the computer hardware what to do and when to do it. • Application software: performs a specific data-processing function (word processing, accounting, etc).

  8. Security Systems • Must protect against two threats: 1. virus and worms and 2. unauthorized access to the computer. • HIPAA requires: • Virus detection and elimination software • Unusual activity must be reported • Intrusion detection tools should be installed • Firewalls suggested to limit type of files that can be transmitted.

  9. Ergonomics • Defined: scientific study of work and space; influences worker productivity that affects workers’ health. • Concerns with computers: • Eyestrain (antiglare screen) • Carpal Tunnel Syndrome • Posture

  10. Common Software • Word Processing is used for: • Reports, medical transcription, memos, business letters, and articles. • Benefits of Word Processing: • Allows quick production of a document • Corrections can be made easily • Material can be cut, copied or pasted from other frequently used documents. • Much faster than typing.

  11. Structuring or Defining a Database • Databases are needed to maintain general patient identifying information in fields such as: • Patient name • Patient address • Work phone • Home phone • Patient insurance

  12. Structuring/Defining a Database Cont’d • Other fields might be included: • Sex • Social Security number • Date of birth (DOB) • Occupation • Place of employment

  13. HIPAA Standards for Patient Health Information • Preparation and implementation of written confidentiality protocols and procedures. • Staff training and implementation of all protocols. • Identification and authentication protocols for all personnel. • Access control of computer output, modification, or destruction of files. • Security of transmitted data • Control of discarded records, storage media, and computer hardware.

  14. Professionalism Areas of professionalism directly related to the medical office may include: • Working as a member of the health care team; actively involved. • Adapt to change. • Work ethic and use of computer. • Enhance skills through education.
