How to convert HL7v2 to FHIR in AWS

Hello,

Tim here with the Serverless Support Team and came across your question. There is not currently a reference implementation/architecture for converting HL7v2 messages to FHIR json format that I could recommend myself, however it does appear that the link you had shared, https://github.com/aws-samples/fhir-hl7v2-integration-transform , is an excellent starting position. You could raise a GitHub issue on that repository here, https://github.com/aws-samples/fhir-hl7v2-integration-transform/issues, but it looks for implementing it would mainly just be running the CDK and determining how to integrate the two.

As I'm not familiar with the solution I can only advise on an as-is best effort basis myself, but perhaps simply merging the API resources/methods between the two solutions, and keeping the backend for the HL7v2 for a specific endpoint would suffice? I could not say for sure, but I think generally it's going to be specific to your own unique needs, so looking over the solutions and designing your own system referencing these may be good. I have found that launching solutions and scaffolding my own custom engineered solution via adding CloudFormation or CDK code is one of the best strategies since most everyone’s solutions would be custom with their own features and design constraints.

Thanks for the insights, we have tons of custom mappings that are internal to our product. This seems to be a good place for me to start. We'll reach out if we plan to write a generic framework for transformation in our company. I'm not sure if healthlake partners will help at this point, but will be sure to evaluate for future needs. Though medical comprehend looks interesting, and wonder if I can use that to infer hl7v2 data and build a fhir wrapper on top of it.
