/fhir/r4/{query_endpoint_alias}/Patient

This path retrieves a list of patients that meet supplied query parameters.

The Oracle Health Clinical Data Exchange engine has an enterprise master patient index (EMPI), which uses the search matrix algorithm when matching patients to your search criteria.

Each patient is matched for each item on the following list:

  • LN - patient last name
  • FN - patient first name
  • DOB - patient date of birth
  • SSN - Social Security Number
  • Address - concatenation of AddressLine1, AddressLine2 and sub-rule evaluation of Postal Code values
  • Phone - phone number provided, can be mobile/home/work

The list below is ranked in priority from highest to lowest:

Sub-rules are the only rule sets which can make use of the following functions (normal rules are only YES/NO):

  • Unknown - If the field is unknown rather than a known, different value
  • yearMatches - Year of DOB value matches
  • maxlev(x) - custom Levenshtein evaluation tolerance
  • exact - fields are exact character match
  • exactAndMaxFreq(x) - If fields are exact match and the content occurs in less than x-value percent of total patient population
  • postalMatches - Postal Code of the address field matches
