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

Slide 7

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

Slide 8

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

Slide 9

IHC Plans - Future

More WDS service interfaces Primary Care Maternity

Tracing wider than Wales / England Other services on patient identification

Slide 10

Action for NADB

Approve concept of WDS Existing set of systems Transition to Services

Approve primary focus of initial WDS project Business continuity
