Health IT Hardware Overview Computer Components Virtual Components Tour Evolution of Health IT Processing Network Fundamentals Data Switches for the Health Internet
The Health IT Pyramid Hardware Decision Support Software Life Support Software Clinical & Financial Data
Hands On Components of Health Information Technology
Major Components of a Computer System Input Output 1. Arithmetic/Logic 2. Control Unit 3. Registers Secondary Storage Primary Storage CPU Information Control
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.
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)
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)
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
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
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.
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.
