Impact of NPfIT

• Plans
• Existing systems being replaced
• PDS taking on most functions
• GP systems link to PDS not NHAIS
• Implications for NHS Wales
• Ensure continuity of existing functionality
• Either provide links to PDS
• Or provide separate systems for Wales
• Cost implications

Patient Identification

• WDS provides only some functions needed
• Overall requirement
• How do you link an individual with an identifier,
  and hence to the information associated with that
  identifier?
• Other areas to be considered
• Linking local identifiers to national identifier
• Search facilities in clinical portal
• Patient list management
• Physical identification
• Separate paper to NADB

IHC Plans - Current

• Initial WDS project
• Develop initial service interfaces to WDS
• Ensure continuity of existing services
• Allocation of NHS numbers
• Links to external bodies
• Provide tracing solution
• Use PDS as replacement for NSTS
• Possible UK interoperability hub

IHC Plans - Future

• More WDS service interfaces
• Primary Care
• Maternity
• Tracing wider than Wales / England
• Other services on patient identification
