Send athena practice ID in FHIR search queries

[mthrilok]

Hi Dragon,

Each practice in athenaNet has it's own FHIR url as below: https:athenanet.athenahealth.com/432/52/fhir/r4 https:athenanet.athenahealth.com/1959/52/fhir/r4

We have a FHIR API Router that can route a request to the correct backend FHIR server. https://api.fhir.athena.io/fhir/r4

When we make search queries to FHIR API Router, we have to pass the ah-practice parameter for the FHIR API Router to identify the correct athena Practice. The athena practice id can be pulled from the athena patientId which is in format a-.E- or we can pass the practice id to the systemLaunch as parameter and the app can store and use it.

Below subroutines in com.drajer.sof.utils.FhirContextInitializer performs search query based on patient id: getResourceByPatientId getObservationByPatientId getResourceByPatientIdAndCode

As discussed in call (on 18/11/2021) could you take a look on this request and prioritize. Please let us know if there are any queries on this request. Thanks

hi Dragon,

• As discussed during our last call , please find more details on athena practice ID.
• FHIR router url is responsible for routing to the correct practice using the practice id.

In below examples "432" and "1959" represents athena practice id . https:athenanet.athenahealth.com/432/52/fhir/r4 https:athenanet.athenahealth.com/1959/52/fhir/r4

• At athena we have thousands of practice ids , so we maintain FHIR router url which will route the request to correct FHIR practice url . Therefore we need practice id for the FHIR router url to route it correctly.

Suggestions to Fix:

• Option 1: We can pass the practice id to the systemLaunch as parameter and the app can store and use it.
• Option 2: practice id value can be pulled from the athena patient_id which is in the format "a-.E-" and then the app can use practice_id to append in the url.
• Below subroutines in com.drajer.sof.utils.FhirContextInitializer performs search query based on patient id needs to be updated: getResourceByPatientId getObservationByPatientId getResourceByPatientIdAndCode
• Current url : /resourceName?patient={patient_id}
• Expected url :/resourceName?ah-practice=Organization/a-1.Practice-{practice_Id}&patient={patient_id} [ Parameter Name= ah-practice , Parameter Value = Organization/a-1.Practice- {practice_id}]

Please let us know if there are any queries , we can set up a quick call and discuss if required. Thanks

CAn you check if you can use any HTTP header parameters that can be used for the context ?

We have fixed this from athena side hence closing this one.
