CCTOS Common : Patient Identification

• Objectives:
  • Issues related to patient identification.  
• Approaches:
  • Derived from Agent:
    •  Additional properties for the notion of patient, or more generally speaking the "subject of care".
  • Search procedures:
    • Several methods:
      • By means of the patient identification number.
      • By means of the identification descriptors:
        • The association of several descriptors as first and last name, optional husband name, date of birth, sex, etc...  making the identification very likely although none of these attributes is unique in large populations.
      • By means of participation in a group:
    • Reliability:
      • In general a search should provide a feed back with more information which should be checked and confirmed by the user.
      • The reliability should be quantified, particularly in the cas of identification by means of descriptors in large populations.
    • International dimension:
      • Patient identification should be world wide, including displaced people and migrants.
      • A world unique prefix should be always added. Of course in practice made implicit for nationals.
    • Although the goal is to centralize the patient record, it can happen the a patient could have several records. When this is discovered, links between the record of the same patient should be registered.
  • Access rights:
    
    • Control of access rights to the patient record, or some aspects of the patient record.
    • Critical conditions:
      • In function of the user authorization profile. How far is access to given types of data allowed at all.
        
      • In function of the role of the user for this particular patient.  If not caring for the patient, no access.  These access rules are maintained in function of the current "Care Team" of the patient.
