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

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

5 Hands On Components of Health Information Technology

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

7 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.

8 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)

9 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)

10 Input Devices Keyboard Pointing device – mouse – trackball – pointing stick Scanner Handwriting recognition devices Voice input

11 Output Devices Printer – Dot matrix – Laser – Inkjet Monitor Speakers

12 Motion Activated Security Quad Processor Servers Satellite Uplink Welcome to Prof. Parentes Enterprise Servers

21 Secondary Storage II Floppy Drive Hard Drive

22 Secondary Storage III SCSI/SATA Hard Drive DVD

23 Primary Storage RAM Peripheral Slots

24 Power Supply Backup & Modem Modem Uninterruptable Power Supply (UPS)

25 Central Mainframe

26 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

27 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

28 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.

29 1990s-Realizing integrated IS Radical market change in health markets has completed radical in IT change. – mergers – integrated delivery systems – Health reforms 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.

30 Intel processor mainstream purchase timeline: : 8 bit XT : 16 bit AT : 16 bit : 32 bit : 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.
