What is the best way to create an HL7 message from JSON input file?

We have JSON file available with data required for building the HL7 message . I am trying to use a standard file/FTP Business service to pick up the file and convert the input %FileCharacterStream into a dynamic Object and use the stand JSON features to read /process the data and build the HL7 message.

Is there any other better way to do this? or any standard built-in functionality available in HealthShare?

Thanks you for your help

I have a project to only filter certain pathology results into a downstream system.

Within a HL7 router and business I was planning on using a lookup table and either the exists() or Lookup(), but am having issues when using it with repeating fields or segments.

For example if I perform teh analysis per stated segment usign {} brackets this will work, as each stated repeat is assessed:

Hi,

I need to develop a HL7 Q22/K22 query/response mechanism for a NHS Trust I am working for, but I do not know how to handle the message continuation.

Can any one give me any advise on this and/or point me in the direction of any documentation on the subject?

Thanks

I am looking to create a routing rule that will do the following:

When transaction is not an A03, and discharge date is valued, do not transform.

What I am having trouble with is with the conditional for the discharge date {PV1:45}. Not sure if I can use length here or if I can use HL7.{PV1:45}>0. I did try that, but its not working. Not sure what I am doing wrong.

Thanks,

Nicole

HL7 - FHIR

Hi All,

I know hundreds of people have done this but I'm looking for some DTL's as a start to do HL7 to FHIR, I appreciate everyone's HL7 is slightly different, but just some starter DTL's would be much appreciated? Can anyone help?

Hello,

I am trying to create a HL7 message (REF_I12 message) using variables extracted from a Dynamic Object and need some advice about segment creation issues that I am having. Some background info: I receive a JSON response from an API call and used %FromJSON to convert the response to an Dynamic Object. Some of the items in the response are repeated such as NOKName, NOKrelationship.

Hi

I would like to create a new message of a particular type and append various segments programmatically. I have started with the following snippet. What I am currently finding difficult is to define a segment of a particular segment structure. I would like to append a pid segment of 2.3.1 to my message. I know I could you the importfromstring but I wanted to know whether there was a better way of achieving this.

Hello, we would need some help:

We would like to use a Transformation to convert an ORU_R30 2.3 to ORU_R30 2.5

However Ensemble does not have a HL7 Schema for ORU R_30 2.3

So then our original message is not being recognized:

→ How could we let Ensemble recognize the ORU R30 2.3 structure to be able to use a Transformation?

We have read:

suppressing a patient identifier

Hi all

Another newbie question.

A small percentage of our patients have an extra hospital number which was imported from the previous PAS but is no longer in use. We only need to send MRN and NHS number and would like to suppress CMRN. Could you please advise me how to do it in DTL?

modifying patient address in DTL

Hi

Newbie question. Could you please help me implement the following using DTL only - no programming.

We have a problem where our system sends longer addresses e.g. block of flats in an unexpected format

e.g. address below:

Hi

We have several rules in router to validate HL7 messages, each rule check a particular field in HL7 message and send back response. We want to run all rules and combine the rules responses into some variable/object and at the end if variable/object is empty it means message is valid, else send the value from this variable/object. This way one message we dont run it again and again, and we can send one message and response will give us combine results from all rules.

For example,

Rule 1 - Check MSH.12 field, Send response "MSH.12 value not valid", and RETURN

Date Filtering Functionality

I have come across several cases where I need to set a Date filter to send only send any admit/scheduled date past a certain point. We have a couple different date comparison functions but none looking at the true date. Most of them are date + 15 or etc. Does anyone have a good date function they have written to say if x > 20170102 ?

Thanks
