Hardware • Physical equipment of computers and computer systems • CPU • Scanner • Printer • Consists of both electronic and mechanical equipment
Software • Set of instructions required to operate computers and their applications • Operating system software: • OSX, Windows, Linux, UNIX • Application software • E.H.R., Microsoft Word, auto-back-up, etc.
File Sizes Kilobyte (KB) = 1,000 bytes Megabyte (MB) = 1,000 kilobytes Gigabyte (GB) = 1,000 megabytes Terabyte (TB) = 1,000 gigabytes
Categories of Computers • Supercomputers • Used in large scale activities • Mainframe systems • Only available until 1960s • Midrange systems • Minicomputers – introduced in 1960s • Workstations
Categories of Computers • Microcomputers • AKA Personal Computers (PC) • Variety of sizes [desktop, laptop, tablet, etc.] • Web appliances • Used in conjunction with the Internet
Computer Peripherals • Input devices: keyboard, scanner, microphone, mouse, etc. • Output devices: monitor, printer, speakers • Processing and memory: CPU (central processing unit); RAM, ROM
Computer Peripherals Storage Devices: hard disk drive, jump drive, CD Rom, DVD, etc. Communications devices: modems
Information Systems A process that refines raw facts into meaningful information Integration of several elements of a business process Create competitive advantage by improving operations and improving patient care delivery
System Characteristics • Components that act together to accomplish a specific objective • Adapt and respond to environmental changes • People • Data • Work processes • Information technologies
Health Information System (HIS) Patient scheduling, admission/discharge processes, and patient transfers Business and financial systems: Patient accounting and billing] Communications and networking: interdepartmental communications
Health Information System (HIS) Department-specific systems: Radiology, pharmacy, etc. Documentation systems: collect, store, and retrieve patient data Reminder and advice systems: evidence-based medicine, patient care activities
System Development Life Cycle Request for development Requirements and system analysis System design Specific functions
System Development Life Cycle Computer program coding Testing of systems Development of system documentation User training
System Development Life Cycle User conversion Operating of the system System maintenance System changes and upgrades
Nolan’s Six-Stage Theory Initiation of automation Expansion of automation Control of information technology Integration of systems Data administration Maturity of system’s involvement with organizational strategic planning
Database Management System (DBMS) Integrated set of programs to manage access Software that supports the operation of database Personal DBMS: small projects Server-based DBMS: links multiple tables and maintains consistency
Databases Organized integrated collection of data segmented into fields, records, and files Structured file to store data as well as edit, query, and retrieval of data
Levels of Data Organization Item - data that describes an object Record – items related to each other File – records related to each other Database – structured file for data storage
Database Models • Relational • Data stored in pre-defined tables with columns and rows (e.g. spreadsheet) • Heirarchial • Treelike structure of parent/child relationships • Network • Treelike structure, child with many parents • Object-oriented: stores objects like pictures • Object-relational: relational + object-oriented
Types of Organizational Databases • Transactional • AKA operational or production database • Detailed data to support facility organization • Analytical • Supports strategic and tactical decision-making • Extracted pieces of data • Distributed • Support specific local applications
Types of Organizational Databases • External • Obtain information from sources outside the organization • Data Warehouse • Integrate organization-wide data into single repository • Sets up large stores of data • Data Mart • Subset of data warehouse • Data Mining • Data used to explore relationships within existing data
Information Security • Privacy • Right to limit access by others to some aspects of personal information • Confidentiality • Information collected will be used for purpose for which it was gathered • Security • Control access and protect information • Informational Privacy • Keep information from begin disclosed to anyone
Security Fundamentals Protect privacy of patient-related data from intrusion Ensure integrity of information Ensure availability of information to authorized users in a timely fashion
Security Protocols • Establish a security organization • chief security officer, privacy officer, etc. • Implement employee awareness program • Conduct risk analysis and assessment • Establish access control • Tracking system
Security Protocols • Implement physical and management controls • passwords, locked doors, limited access • Develop a disaster recovery and business community plan • disaster plan • Implement network controls • virus protection
Prevention and Control • Personnel • Employee access based on “need to know” • Physical • Secure equipment from any threats • Hardware • Temperature-controlled, power outage protection
Prevention and Control • Software • Audit trails, integrity controls • External • Firewalls, encryption, SSL protocols, etc. • Communication • Authentification, system knows user is authorized
New & Emerging Technologies • Videoconferencing • Skype, FaceTime, GoTo Meeting • Groupware • Integrated work flow (e.g. Google Documents) • Information kiosk • Patients and visitors have access to variety of data • Speech recognition • Voice controls, dictation (voice-to-print)
New & Emerging Technologies • Telephone interface systems • Computer-telephone integration • VOIP (Voice Over Internet Protocol) • Website support: customer service or tech • Telemedicine • Electronic exchange of clinical data
New & Emerging Technologies • 3D imaging • All three spatial dimensions • PDA/Smartphones • Portable computing, faster access to data • Wireless networking • Smart Cards
Network Architecture • Local Area Network (LAN) • Connects computers in small area • Client-server network • Peer-to-peer network • Hybrid network (client-server + peer-to-peer) • Wide Area Network (WAN) • Connects computers over large area • Two or more LANs connected together
Internet Protocols Thousands of loosely connected WANs Relies on software called “browsers” (eg. FireFox, Safari, Internet Explorer) IP = Internet Protocol, a unique address for each and every computer TCP/IP = protocol for transmission of data HTTP = hypertext transfer protocol HTTPS = hypertext transfer protocol secure
Internet Language HTML = hypertext markup language SGML = standard generalized markup language XML = extensible markup language JAVA = programming language
Intranet Special type of LAN Uses Internet to connect members of one organization Accessible to only authenticated users
E-Commerce • Marketing, buying, selling, and support of products and services using the Internet • Supports patient education initiatives • May include EFT (electronic funds transfer) for payments • Enhance convenient patient/provider services • Physician referral services • Requests for ROI, etc.
Information Resources Management (IRM) • All management concepts related to • Creation • Usage • Storage • Disposal Of business-related information
Information Resources Management Integration strategies for data information processes: computer and manual Identifies information as a valuable organizational and industrial resource CIO = Chief Information Officer
