IT Infrastructure Example

1. IT Infrastructure

2. Hospital Information System
• A hospital information systems (HIS) is a computer system that
is designed to manage all the hospital’s medical and
administrative information in order to enable health
professional perform their jobs effectively and efficiently.
• Hospital information systems were first developed in the
1960s and have been an essential part in hospital information
management and administration.

3. Modules of HIS
• Clinical Information System (CIS)
• Financial Information System (FIS)
• Laboratory Information System (LIS)
• Nursing Information Systems (NIS)
• Pharmacy Management System (PMS)
• Picture Archiving Communication System (PACS)
• Radiology Information System (RIS)

4. Architecture of HIS
• Generally in client-server architectures for networking and
processing.
• Either desktop based or web-based
• Cloud Computing

5. Benefits
Easy Access to Patient Data to generate
Internet-based access improves the ability to remotely
access such data.
It helps as a decision support system for the hospital
authorities for developing comprehensive health care
policies
Efficient and accurate administration of finance
Improved monitoring of drug usage, and study of
effectiveness.
Enhances information integrity, reduces transcription
errors, and reduces duplication of information entries.
