STU3 -> R4 Conversion Medication Request Date Issue

[dadams300]

When using the STU3 -> R4 template for conversion. I received an error trying to load the transformed data into the MSFT FHIR server. The issue is specific to the date being converted occurrence date time. This is data created with Synthea.

STU3 - Data for immunication
"fullUrl": "urn:uuid:9f5a4cc9-2d28-c259-3f74-9d4f76b7b0ba", "resource": { "resourceType": "Immunization", "id": "9f5a4cc9-2d28-c259-3f74-9d4f76b7b0ba", "status": "completed", "notGiven": false, "vaccineCode": { "coding": [ { "system": "http://hl7.org/fhir/sid/cvx", "code": "140", "display": "Influenza, seasonal, injectable, preservative free" } ], "text": "Influenza, seasonal, injectable, preservative free" }, "patient": { "reference": "urn:uuid:3d869c88-c6bb-443d-0c35-924c131af87c" }, "encounter": { "reference": "urn:uuid:c9894b58-a8c7-45ee-4168-71860a5d29ad" }, "date": "2022-04-05T03:06:43-04:00", "primarySource": true }, "request": { "method": "POST", "url": "Immunization" } } ] }

R4 - Converted Data
{ "fullUrl": "urn:uuid:9f5a4cc9-2d28-c259-3f74-9d4f76b7b0ba", "resource": { "resourceType": "Immunization", "id": "9f5a4cc9-2d28-c259-3f74-9d4f76b7b0ba", "status": "completed", "vaccineCode": { "coding": [ { "system": "http://hl7.org/fhir/sid/cvx", "code": "140", "display": "Influenza, seasonal, injectable, preservative free" } ], "text": "Influenza, seasonal, injectable, preservative free" }, "patient": { "reference": "urn:uuid:3d869c88-c6bb-443d-0c35-924c131af87c" }, "encounter": { "reference": "urn:uuid:c9894b58-a8c7-45ee-4168-71860a5d29ad" }, "primarySource": true, "occurrenceDateTime": "4/5/2022 7:06:43 AM" }, "request": { "method": "POST", "url": "Immunization" } } ]

The Error when loading

{ "resourceType": "OperationOutcome", "id": "8dc1e8bab75040651048e4442e8cad73", "meta": { "lastUpdated": "2023-02-15T20:03:39.1047298+00:00" }, "issue": [ { "severity": "error", "code": "invalid", "diagnostics": "Error occurred when parsing model: 'Type checking the data: Literal '2/18/2014 7:06:43 AM' cannot be parsed as a dateTime. (at Resource.entry[81].resource[0].occurrenceDateTime[0])'." } ] }

Perhaps the STU3 -> R4 Template could be modified to:

"occurrenceDateTime" : "{{ msg.date | date: "yyyy-MM-ddTHH:mm:ss.fff%K" }}",

Investigated the issue, the root cause is:

• The value get converted at here: https://github.com/microsoft/FHIR-Converter/blob/main/data/Templates/Stu3ToR4/Immunization.liquid#L18
• the Datetime type was converted to String type from here: https://github.com/dotliquid/dotliquid/blob/master/src/DotLiquid/Variable.cs#L75
• The default IFormatProvider was used, so it didn't get printed out in expected format.

Now I'm exploring the fixing options.

@dadams300 Please feel free to use the code you pointed out when you run this template outside of the Azure FHIR service. I have tested it and it should work. But if your work depends on the Azure FHIR service, it will take some time for us to roll out the change.

In the meantime, I'm exploring other long-term solutions.

We have a few longer-term options but those would require more fundamental refactoring. The template update seems the best temporary solution at this point. It's consistent with the design and the usage of it in other templates as well.

@dadams300 Please feel free to submit a PR if you wanted. Thank you!

There is no response from the user who originally reported this issue and proposed the code to fix, I'm going to create a PR.
