Need ……

National Health Information System (NHIS)

“the transparent and secure access to health information across geographically distributed healthcare centers”

Objective: for better national public health policy

• healing and controlling diseases
• promoting good health
• health personnel
• efficient use of budget

4

Things to be Considered

• Diversity: health information structures among healthcare centers

(approximately 30 different data structures)

• Availability: information sharing from healthcare centers
• Accessibility: efficient information access to at least 10,000

healthcare centers

• Privacy and privilege of heath information

5

NHIS Pathway

• Phase I

: Information Transformation

– Objective

• to enable the interoperability & usability of health information across

healthcare centers

– Goal

• National Health Metadata Standard
• Metadata Mapping Tool (MMT)
• Metadata Conversion Tool (MCT)

– Technology

• XML
• Rich Interface Application

NHIS Pathway

• Phase II: Information Sharing & Interoperability

– Objective

• to make health information sharing possible
• to provide an efficient information access to a large number of

healthcare centers

– Goal

• Metadata Service (MS)
• Metadata Broker (MB)

– Technology

• Web Services, XML, P2P

NHIS Pathway

• Phase III: Information Security

– Objective

• to promote the privacy and privilege of health information

w.r.t. consumers’ roles

– Goal

• Authorization Service (AS) - verifies user credentials and generates data access policy
• Extended Metadata Service (MS) - handles information security issues
• Extended Metadata Broker (MB) - handles information security issues

– Technology

• Public Key Infrastructure (PKI)
• Privilege Management Infrastructure (PMI): Role-based Access Control (RBAC)
• Web Service Security Standards

Current Work

• MMT & MCT Evaluation by

– 3 Software Vendors as HIS developers

• HOSxP

45% of medium-large healthcare centers

• HospitalOS 10% of medium-large healthcare centers
• JHCIS 80% of small healthcare centers

– 10 Healthcare centers as health information owners (providers)

• 5 small healthcare centers
• 5 medium healthcare centers
• MMT & MCT Maintenance & Extension w.r.t

– Large-scale health information – System performance

• NHIS Architecture Design to support tasks in Phase II
