Agenda
● What is FHIR and Why to use it?
● Why MongoDB Atlas?
● Why MuleSoft?
● Error Handling
● Correlation ID
● Customer Story
● Demo

17. All contents © MuleSoft, LLC 17
● Supports RESTful architectures:
seamless exchange of information
using messages or documents, and
service based architectures
● XML or JSON as the data
transmission format
● A strong focus on implementation –
fast and easy to implement.
● Independent of any one EHR vendor,
health system, or other for-profit health
entity

● MongoDB Atlas is a fully-managed cloud
database
● Atlas handles all the complexity of deploying,
managing, and healing MongoDB deployments
on the cloud service provider of your choice
(AWS, Azure, and GCP).
● MongoDB and FHIR both support the JSON
format, which is extensively used in modern
application development due to its’ ability to
support rich data structures and objects
prevalent in healthcare, such as patients,
claims, policies, treatments and so on

19. All contents © MuleSoft, LLC 19
● Provides plug and play connector for HL7 and MongoDB Atlas.
● Provides a large number of operations and configurations on the data and the
database.
● Can work on simple request and response mechanism where a
user/application can send a request to MuleSoft integration and expect an
operation to be done to their FHIR data
Why MuleSoft?

Error Handling in MuleSoft
● Requirement :
○ Stop the processing if there is any error while converting one format to another.
○ Do not retry until the error in the input data is fixed.
○ Send an email notification mentioning the error.
● On Error Propagate:
○ All processors in the error handling scope are executed but at the end :
■ The rest of the flow that threw the exception is not executed which means nothing will be added to
MongoDb
■ The error is re-thrown up to the next level and handled there.

Correlation ID
● Common Identifier to all requests, messages and
responses in each transaction.
● A Correlation ID with a log entry helps in
implementing auditing.
● On failure, we just need to check the logs as per
correlation ID to get combined transactional activity
among all microservices.
● In the screenshot on the right you can see the
CorrelationID being forwarded to all Microservices.
● Screenshot below shows how in the logs we can find
audit trail of any transaction using CorrelationID.

Customer Story
● Customer tried building the converter in Java but it was a very long process.
● Customer was looking for various ways to store FHIR data for example smileCDR,
which is expensive and since it is third party, it is not completely under your control.
