Information Technology Method used to: Process Process Protect Protect Store Store Transmit Transmit Retrieve RetrieveDATA

Health Information Technology (HIT) Information Technology is the wave of the future for healthcare management HIT- refers to the technology used to create, transmit, store, secure and manage an individual’s health data. Currently electronic health data is limited to a single healthcare system, facility or office.

Concept of using IT in healthcare The concept of interoperable sharing of health information will authorized entities access (i.e. physician's, billing) IT use in healthcare is a expanding c oncept to have an impact on: Enhancing healthcare safety Decrease healthcare cost, and Enhance healthcare quality The need has been recognized by the private sectors and at the highest levels of government

Define modern health information technology. Use of computer hardware and software to manage health care information Use of computer hardware and software to manage health care information Increases legibility Increases legibility

Data The vision is that reliable health-related information will exist electronically in a format that can be securely and easily accessed by authorized agencies to: The vision is that reliable health-related information will exist electronically in a format that can be securely and easily accessed by authorized agencies to: Improve the health of the individual Improve the health of the individual Improve health a community Improve health a community And ultimately of the U.S. population as a whole And ultimately of the U.S. population as a whole

Datacontinued Data continued. Health information is obtained, entered electronically, stored and retrievable to promote continuity among providers Health information is obtained, entered electronically, stored and retrievable to promote continuity among providers Data entered electronically promotes adherence to the National Patient Safety Goals (NPSG) Data entered electronically promotes adherence to the National Patient Safety Goals (NPSG) The Joint Commission lists the current standards and goals on its website: The Joint Commission lists the current standards and goals on its website: on/npsgs.aspx on/npsgs.aspx on/npsgs.aspx on/npsgs.aspx

Data Storage After data is converted into bits, it can be stored in bytes (a string of 8 bits) After data is converted into bits, it can be stored in bytes (a string of 8 bits) Primary storage, or memory, is located in the hard drive and can be directly accessed by the central processing unit (CPU) Primary storage, or memory, is located in the hard drive and can be directly accessed by the central processing unit (CPU) Secondary storage: located outside the computer; ex: disks, CDs, USB sticks, external hard drives Secondary storage: located outside the computer; ex: disks, CDs, USB sticks, external hard drives Good for security purposes Good for security purposes

Challenges of Healthcare Data Protection Prevention of data corruption Prevention of data corruption Limits access to data Limits access to data Disk encryption Disk encryption Backup – internal or external copies of data files in case of accidental data loss Backup – internal or external copies of data files in case of accidental data loss Data masking – hiding specific private data within a database Data masking – hiding specific private data within a database Data erasure – destroys all electronic data on a hard drive to maintain privacy if it is discarded or reused Data erasure – destroys all electronic data on a hard drive to maintain privacy if it is discarded or reused

Data Processing Conversion of data into usable information Conversion of data into usable information Fetches instructions for a program from memory Fetches instructions for a program from memory Decodes and reads instructions Decodes and reads instructions Portions of the CPU connect and execute instructions Portions of the CPU connect and execute instructions Writes back the results to memory Writes back the results to memory

Data Transmission Physical transfer of data over a medium, such as copper wire, optical fiber, or wireless Physical transfer of data over a medium, such as copper wire, optical fiber, or wireless Networks: enable two or more computers to share files, printers, and communicate with each other Networks: enable two or more computers to share files, printers, and communicate with each other

Health Information Networks Local Area Network (LAN): contained within one healthcare practice or hospital commonly referred to as an intranet Local Area Network (LAN): contained within one healthcare practice or hospital commonly referred to as an intranet Wide Area Network (WAN): connects several healthcare practices or hospitals Wide Area Network (WAN): connects several healthcare practices or hospitals Ex: Internet Ex: Internet

Health Information Networks, continued. Client-server: Healthcare organization computers are all connected by a central server; can be LAN or WAN Client-server: Healthcare organization computers are all connected by a central server; can be LAN or WAN Peer-to-Peer: Healthcare facility or office practice computers are connected to each other, but files are not stored in a central location; can only be LAN Peer-to-Peer: Healthcare facility or office practice computers are connected to each other, but files are not stored in a central location; can only be LAN

Health Information Networks, continued. Server: large & powerful digital storage point that performs a service for other computers in a network; file, print, web, mail is used to maintain patient information Server: large & powerful digital storage point that performs a service for other computers in a network; file, print, web, mail is used to maintain patient information Use of a server makes it easier to maintain security and perform backups when health information files are centrally stored Use of a server makes it easier to maintain security and perform backups when health information files are centrally stored Health Information is protected by HIPAA (Health Information Privacy and Accountability Act) Health Information is protected by HIPAA (Health Information Privacy and Accountability Act)

Internet With the advances in technology, the internet is used for obtaining and providing health information With the advances in technology, the internet is used for obtaining and providing health information IP Address: each computer has one; enables data to be sent to and received from a specific computer and creates an electronic fingerprint for legal purposes IP Address: each computer has one; enables data to be sent to and received from a specific computer and creates an electronic fingerprint for legal purposes

Data Retrieval “Science of searching” “Science of searching” User enters a query (ex: search string on web search engine or computer hard drive) User enters a query (ex: search string on web search engine or computer hard drive) Computer information retrieval system scores objects in database by relevancy and displays those most relevant to the query Computer information retrieval system scores objects in database by relevancy and displays those most relevant to the query

Common IT Applications Word processors: used to create and edit documents Word processors: used to create and edit documents Spreadsheets: used to analyze figures and present information with graphs/charts Spreadsheets: used to analyze figures and present information with graphs/charts Databases: stores information about a set of similar items Databases: stores information about a set of similar items

Common IT Applications Publishing: more control over formatting and arranging than word processing Publishing: more control over formatting and arranging than word processing PowerPoint: used in business presentations and the classroom to present factual information or for persuasive purposes PowerPoint: used in business presentations and the classroom to present factual information or for persuasive purposes
