Key

  • This line was added.
  • This line was removed.
  • Formatting was changed.
Following are the contract level changes that we have fixed for our bundles to be parseable.

...

Composition                
     new mandatory fields added:
  1. type ->> NEED TO CREATE A VALUESET IN TR FOR THIS. (name is 'doc-typecodes' with document types from loinc).
  2. author,
  3. confidentiality => http://hl7.org/fhir/v3/Confidentiality - code system


Encounter
     subject => patient
     (Fields removed )
     indication

 
Condition
     RelatedItem is replaced by dueTo and occurredFollowing.
     status is replaced by "clinicalStatus"
     dateAsserted date takes only date without tim component. -> Need to investigate how to map bahmni chief complaint duration after this change.

Bundle 

  1. Bundle has to have a type -> Document. Validate this?
  2. base tag is mandated at either bundle level or at individual entry level.

  3. All bundle entry ids must be a uuid, 
    in DSTU1 we had urn:<uuid>, this should be changed to have only <uuid> 
    example:

    DSTU1DSTU2 
    <entry id="urn:5f982a33-4454-4b74-9236-b8157aa8effd"><entry id="5f982a33-4454-4b74-9236-b8157aa8effd">

  4. All reference urls should be either urls starting with http protocol or must be uuid prefixed with 'urn:uuid:'. 

Observation [breaking]
  1. name ==> code.

 

Immunization [breaking]
  1. refusalIndicator ==> wasNotGiven
  2. refusalReason ==> getReasonNotGiven
  3. subject ==> patient

 

MedicationPrescription [not breaking]
  1. dosageInstruction  can now take both dosageQuantity and dosageRange
          [dosageInstruction.dose field can capture two types           dosageQuantity,dosageRange]
To look into later:
Composition:
Confidentiality set to String - A code from the confidentiality vs

...


DrugMapper - MedicationPrescription:

Mapping frequency component along with duration and period (Revisit mapping logic from bahmni treatment to fhir MedicationPrescription. esp duration and frequency)- Needs more analysis and test cases. Just fixed compilation issues.

DosageInstruction needs more analysis. 

Procedure

Procedure.Outcome,Procedure.FollowUp

 - is a codeableconcept from a valueset rather than plain text.We can improve the ui?

Need to capture notes along with procedure
Procedure.DiagnosticReport.result
result is set as just display. Should be set as a reference to observation

Fields that can carry multiple value types 

Ex: FamilyMemberHistory.born - Can take period, date,string. Currently we have handled date types.Should we handle all the types? 


Need More Investigation:- 


  • Drug Order Mapper (upload and download flow)
  • Chief Complaint Mapper (How to map Chief Complaint Duration?) -> Ignored the tests
  • MCIPatientServiceImplIT - should save drug orders.
