• Enabling babies to have an NHS number from birth,
  for life. Important as vital tests and medical
  treatment to be administered in the first six
  weeks of life
• National Health Service Central Register (NHSCR)

  Services (NHAIS)

Personal Demographics Service

• Authoritative source of demographics, using NHS
  number as the key
• Underpins all new national and local services
• Local MPIs regarded as temporary local caches
• PDS must be queried for 4 key business events
• Commencement of an encounter
• Communication with a patient
• Start and end of an in-patient episode
• Scheduling an event
• NSTS history was not loaded into PDS, so the
  former is used for data cleansing prior to
  migration
