The document outlines the role and architecture of healthcare information systems (HIS) in improving patient care, safety, and administrative efficiency. It discusses terminologies, system architecture, and the components of hospital information systems, emphasizing data management and accessibility. The benefits of HIS include cost-effectiveness, enhanced operational processes, and better patient and clinical support.

1. INFORMATION SYSTEM IN
HEALTHCARE
PREPARED BY,
HEMAXI PARMAR
M.Sc. NURSING (OBG)

2. TERMINOLOGIES
• ADT - ADMISSION, DISCHARGE & TRANSFER
• CERNER - COMPANY THAT SPECIALIZE IN ELECTRONIC MEDICAL
RECORD SOFTWARE
• DISCRETE RESULTS – RESULTS THAT’S BROKEN DOWN INTO
INDIVIDUAL VALUES, UNITS & REFRENCE RANGES.
• DATA EXTRACTION – A PROCESS BY WHICH DOCUMENTS IS SAVED
OFF IN ANOTHER FORMAT THAT CAN BE USED FOR OTHER PURPOSES.

3. TERMINOLOGIES
• EMR – ELECTRONIC MEDICAL RECORD
• HIM – HEALTH INFORMATION MANAGEMENT
• CLINICAL INFORMATICS – THE STUDY OF INFORMATION
TECHNOLOGY WITHIN HEALTH CARE CONDUCTED BY AND FOR
CLINICIANS.

4. ROLE AND ARCHITECTURE OF INFORMATION
SYSTEMS:
• A COMMON WORD USED TO DESCRIBE ELECTRONIC SYSTEM CREATED TO
MANAGE HEALTHCARE DATA IS HEALTHCARE INFORMATION SYSTEM, ALSO
KNOWN AS “HIS”.
• HCISs AS POWERFUL ICT-BASED TOOLS ABLE TO MAKE HEALTHCARE DELIVERY
MORE EFFECTIVE AND EFFICIENT.

Secondary care

8. TYPICAL HEALTHCARE INFORMATION
SYSTEM ARCHITECTURE
• THE ARCHITECTURE PLAN OF HOSPITAL NEEDS SOME OF THE PHYSICAL
LAYOUT WHICH LAYOUT EHICH ARE AS FOLLOWS:
ADEQUATE PROCESSING SPEED
SUFFICIENT AMOUNT OF RAM TEMPORARILY STORE DATA, WHILE IT IS
BEING VIEWED OR TYPED
A MONITOR WITH A DISPLAY THAT CAN SHOW BOTH DATA AND APPS
DATA ENTRY DEVICES, SUCH AS KEYBOARD, BAR CODE READER, IMAGE
SCANNER, MOUSE.

9. HOSPITAL INFORMATION SYSTEM HYBRID
• THICK HYBRID
CLIENT PCs WITH QUICK CPU &
LOTS OF RAM MEMORY ARE
NEEDED
APPLICATION SOFTWARE IS
EITHER FULLY OR PARTIALLY
INSTALLED ON THEM.
• THIN HYBRID
ONLY BROWSER IS LOADED
WHEN NECESSARY, APPLICATION
OBTAINED FROM APPLICATIONS
SERVER.

10. WEB NETWORK
DOMAINS ARE ALTERNATIVE FORMS OF CLINICAL
APPLICATIONS AND DISTINCT DATABASES.
IT CONSIST OF:
PRODUCTION
AND OPERATION
DOMAIN
ANALYTICAL
DOMAIN
TRAIN DOMAIN

11. APPLICATION SERVER

12. • COLLECTION OF LOGICALLY
RELATED DATA STORED IN AND
EFFICIENT AND COMPACT MANNER
• EFFICIENT MEAN STORED DATA
CAN BE ACCESSED VERY EASILY
AND QUICKLY.
• COMPACT MEANS STORED DATA
TAKES UP AS LITTLE SPACE AS
POSSIBLE.

13. NETWORK DOMAIN
• IS A SYSTEM INTERCONNECTE NETWORK OBJECTS, SYSTEM AND
RESOURCES THAT ARE CENTRALLY MANAGED.

14. PHASE 1: SET TO DETERMINE WHO HAS ACCESS TO
DOMAIN.
BY USERNAME AND PASSWORD.
PHASE 2: TRAIN DOMAIN
USER ARE GRANTED ACCESS TO THE DOMAIN THAT
MATCHES THE TYPE OF WORK THEY WILL BE DOING.
PHASE 3: (ANALYTIWCAL DOMAIN) PERFORMING
DATAANALYSIS ON HISTORICAL DATA. (EDITING)
THIS DATABASE CAN BE REPLICATED USING A MULTI
MASTER REPLICATION TECHNIQUE
REFERS TO DOMAIN CONTROLLER

15. PHASE 4: IT DIVIDED UP INTO REPLICATION UNITS CALLED
“DOMAINS”
METHOD OF REPLICATION B/W SERVER COMPUTERS CAN BE SET UP
VERY FLEXIBILITY TO ALLOW COMMUNICATION B/W DOMAIN
CONTROLLER COMPUTERS FAIL, EVEN EFFECTIVELY CONNECTED
VIA WAN CONNECTIVITY WITH LIMITED BANDWIDTH.
PHASE 5: MOST IMP. PURPOSE IS STORAGE OF USER LOGAIN
CREDINTIALS, SO COMPUTER CAN BE SET UP TO USE OF THIS
DATABASE AND PROVIDE CENTRALIZE SINGLE SIGN ON FOR MANY
DEVICES.
PHASE 6: NAME & MEMBERSHIP OF THESE SECURITY GROUPS ARE
STORED.
THE DOMAIN CONTROLLER WOULD ACT AS A BRIDGE BETWEEN THE
FRONT END & THE SERVERS, WHEATHER IT WERE LOCATED ON A
STANDLONE COMPUTER OR INSIDE THE PRIMARY SERVER.

16. EXAMPLE OF HEALTHCARE INFORMATION SYSTEM
ELECTRONIC MEDICAL RECORD (EMR)
SYSTEM FOR CLINICAL INFORMATION (CIS)
PRACTICE MANAGEMENT SOFTWARE (PMS)
PATIENT REGISTRIES
MASTER PATIENT INDEX
REMOTE PATIENT INDEX (MPI)
TOOLS FOR CLINICAL DECISION SUPPORT

17. HOSPITAL INFORMATION SYSTEM
• IT IS THE INFORMATION SYSTEM THAT GATHERS, STORES,
PROCESSES, RETRIVES, AND COMMUNICATES PATIENT CARE AND
ADMINISTRATIVE INFORMATION USING COMPUTERS,
COMMUNICATION TOOLS, AND SOFTWARE.

18. AIMS OF HOSPITAL INFORMATION SYSTEM
PROVIDES THE BEST POSSIBLE ASSISTANCE FOR PATIENT CARE AND ADMINISTRATION.
CAPTURE DATAAS IT IS GENERATED AND SHOW IT WHERE IT IS NEEDED.
ACCURATE DATA STORAGE, QUICK ACCESS TO DATA, SECURE DATA STORAGE &
REDUCED USAGE COST
BETTER ORGANIZE PATIENT CARE
MAINTAIN HISTORIES, PRESCRIPTION, OPERATION & LAB TEST RESULT
DEFAND ORGANIZATION FROM FAULTS IN OFFICIAL DOCUMENTS, EG. OVERSTOCK
ISSUES

19. BENEFITS
• EFFICIENT & PRECISE MANAGEMENT OF FINANCES, PATIENT
FOOD, ENGINEERING & MEDICAL AID DISTRIBUTION
• BROAD PERSPECTIVES ON HOSPITAL EXPANSION
• BETTER DRUG MONITORING & EFFICACY RESEARCH TO
REDUCE UNFAVOURABLE DRUG INTERACTION
• PREVENT ERROR eg. HAND WRITING, MINIMIZE DUPLICATION
OF ENTRY

20. BENEFITS
• USING COMPUTERIZED CLINICAL APPLICATIONS,
HEALTHCARE IS MORE AFFORDABLE.
• EMERGANCY DATA INSTANTLY AVAILABLE
• REDUCE EXTRA TIME & TRAVEL FOR MEDICAL
PROFESSIONALS.
