The healthcare reality

• Volume of patient data increasing exponentially
• Quality of patient data declining
• Fragmented, duplicate and conflicting patient
  information within and across databases andtouch
  points
• Regulatory and safety issues drivenew
  requirements

Critical Data Details

• Over 30 of all Master Person Index (MPI)records
  have an invalid or blank value inname
  (first/last), date of birth or gender
• Jumps to over 60 if middle name counted
• Over 80 of all confirmed duplicate recordshave
  a data discrepancy in one or more keypatient
  identifying fields
• i.e., Name, date of birth, SSN/SIN or gender
• Nearly 40 of all duplicate records havea
  discrepancy in the first or last name

The Basic Questions

• How do I begin to integrate all these solutions?
• Use and insist on IHE Profiles Templates for
  needed interoperability functions
• What do I use to glue these solutions together?
  
• HL7 Messages Healthcare messaging standard
  already used
• What drives access to all the solutions?
• The patient Healthcare is about the patient
  information
• How do I deliver an EHR?
• Find the patient Use IHE Profiles with HL7
  Messages to access the patient records and other
  supporting data

7
Patient Identity Drives Interoperability
The Key to Patient Identity is

• Do we know this patient?
• Is this the correct patient?
• What information do I have about this patient?
• Where did this patient information come from?
• What view do I have of this patient?
• What else do I know about this patient?

8
How Does PIX/PDQ Drive Interoperability
By answering the questions

• Do we know this patient?
• PIX/PDQ Query from client to XRef Manager
• Is this the correct patient?
• PIX/PDQ Manager must handle, accurately, the
  matching and linking with tunable probabilistic
  algorithms
• What information do I have about this patient?
• PIX/PDQ Manager Response to query
• Where did this patient information come from?
• Domain based HL7 Messages Identify sources
• What view do I have of this patient?
• Security applied at the application, PIX/PDQ
  Manager , or both
• What else do I know about this patient?
• Extending the PIX/PDQ Manager and using other IHE
  profiles (i.e. XDS)

  IHE PIX/PDQ Manager functionality
• Choose vendors who have products that support the
  PIX/PDQ client to call the IHE PIX/PDQ Manager
• Feed the IHE PIX/PDQ Manager patient identifying
  information
