Identifier.type.code and value search parameter in not working?

Question

Identifier.type.code and value search parameter in not working?

Thadani, Sanjay (Cognizant) 20

I want to retrieve all patients resources using search param identifier.type.code and identifier.value as shown in below json file attached

Can you tell me the query how do i search for nested elements data inside identifiers?

"identifier" : [{
    "use" : "usual",
    "type" : {
      "coding" : [{
        "system" : "http://terminology.hl7.org/CodeSystem/v2-0203",
        "code" : "MR"
      }]
    },
    "system" : "urn:oid:0.1.2.3.4.5.6.7",
    "value" : "654321"
  }]

@Thadani, Sanjay (Cognizant) To search for nested elements data inside identifiers, you can use the dot notation to specify the nested element. Here is an example query to retrieve all patients' resources using search param identifier.type.code and identifier.value:

GET [baseURL]/Patient?identifier.type.coding.code=MR&identifier.value=654321

This query will retrieve all patients resources that have an identifier with type code "MR" and value "654321". Make sure to replace [baseURL] with the base URL of your FHIR server.

When I try through postman the same query, it is throwing an error as "The chained parameter must be a reference search parameter type"

It seems like you are trying to use a chained parameter, which is not supported for the identifier.type.coding.code search parameter. Chained parameters are used to search for resources that are related to the current resource through a reference.

In your case, you can try using the identifier search parameter instead of identifier.type.coding.code to search for patients with a specific identifier. Here is an example query:

GET [baseURL]/Patient?identifier=urn:oid:0.1.2.3.4.5.6.7|654321

This query will retrieve all patients resources that have an identifier with system "urn:oid:0.1.2.3.4.5.6.7" and value "654321". Make sure to replace [baseURL] with the base URL of your FHIR server.

GET [baseURL]/Patient?identifier=urn:oid:0.1.2.3.4.5.6.7|654321

this is example of system|value for the particular identifier but if i want to search instead of system| value i need to search with type.coding.code and value then how we can write a query

I apologize for the confusion. If you want to search for patients with a specific identifier type code and value, you can use the following query:

GET [baseURL]/Patient?identifier.type.coding.code=MR&identifier.value=654321

This query will retrieve all patients resources that have an identifier with type code "MR" and value "654321". Make sure to replace [baseURL] with the base URL of your FHIR server.

Note that the dot notation is used to specify the nested element "type.coding.code". This tells the FHIR server to search for resources that have an identifier with a coding code of "MR" and a value of "654321".
