  2. Health IT Hardware Overview • Computer Components • Virtual Components Tour • Evolution of Health IT Processing • Network Fundamentals • Data Switches for the Health Internet

  3. The Health IT Pyramid Decision Support Software Life Support Software Clinical & Financial Data Hardware

  4. ‘Hands On’ Components of Health Information Technology

  5. Major Components of a Computer System Primary Storage CPU 1. Arithmetic/Logic 2. Control Unit 3. Registers Output Input Information Secondary Storage Control

  6. Central Processing Unit (CPU) • Arithmetic/Logic Unit • e.g., if diagnosis=‘diabetes’ then count patient • Control Unit • home of the machine code • Registers • place-holders within the CPU as it processes data.

  7. Primary Storage • Core memory: • Read-only memory • Random-access memory • Cache memory • Started off being very expensive • Extremely cheap today relatively to a few years ago (32 MB, $1,280 in 1993; 32 MB, <$1 in 2012)

  8. Secondary Storage • Magnetic disks (e.g., Hard drives) • Magnetic tapes (e.g., Tape drives) • Optical disks • CD (700 MB) • DVD (4,300 or 4.3 GB) • Blu-Ray (25/50 GB) • Smart cards • Solid state drives (e.g., SSD / USB drives)

  9. Input Devices • Keyboard • Pointing device • mouse • trackball • pointing stick • Scanner • Handwriting recognition devices • Voice input

  10. Output Devices • Printer • Dot matrix • Laser • Inkjet • Monitor • Speakers

  25. 1970s - Setting the Stage for Bigger Things • Hardware innovations opened up new opportunities: • On-line computer systems • Still used batch for big jobs (payroll) • Minicomputers • Packaged systems

  26. 1970s - continued • Packages developed: • accounts receivable • admissions • bed census • inventory control • medical records • Turn-key packages: Vendor supplies hardware, software, installation support and training. • Shared systems • use a ‘hub’ • use terminals • forerunner of networks

  27. 1980s • Microcomputers make rapid advances • Institutions faced with more managers wanting systems tailored to their needs. • Led to Balkanization of HMIS. Why? • Technology is cheap • Hospital departments start buying their own stuff • Although stuff was cheap, the new product cycle rapidly accelerated.

  28. 1990s-Realizing integrated IS • Radical market change in health markets has completed radical in IT change. • mergers • integrated delivery systems • Health reform’s promise, threat and debris • Health data standards • Internet/intranet capability • Privacy & security issues • Consumers enter the health care market informed with MEDLINE data and clinical data from the web.

  29. Intel processor mainstream purchase timeline: 1981-2000 • 1981: 8 bit XT 8086 • 1987: 16 bit AT 80286 • 1990: 16 bit 80386 • 1993: 32 bit 80486 • 1995: Pentium (80586) • 1997: Pentium MMX/Pentium Pro (80686) • 1998: Pentium II (80686 w/MMX) • 1999: Pentium III (80686 Slot 2) • 2000: Pentium IV above 1 Ghz.
