In this article I will demonstrate the following :

  • Update ReferencesRange(OBX:7) against ObservationIdentifier(OBX:3.1)[TestCode] from database by using custom utility function
  • Update Abnormal Flag(OBX:8) against ObservationIdentifier(OBX:3.1)[TestCode]  and ObservationValue(OBX:5)[Result] from database utility function
  • Route Message based on Abnormal Flag(OBX:8)

Below is the primary and transformed HL7 2.5 ORU_R01 message:

I am calling a business rule from one of my business processes and I noticed that when the business rule reports an error that the business process calling that rule just stops without any errors. Resultingly it fails to trigger the scope - catch-all construction that is surrounding the business rule. I know that it is possible to view the errors in business rules in the business rules log, but I really like to push an error message to Ens.Alert or something similar when my business rules report an error. How do I achieve that?

Awhile back the Developer community helped me with a situation I was having... How to loop through a Repeating Segment and Single Filed, example OBX().5, within a Business Process Rule and compare it against a Data Lookup table.

Well now I need to take it a step further. I need a way to loop through OBR() segment, and loop through OBR().4() and the subfield 4.1 and compare it to a Data Lookup table.

So I thought I could copy my existing function code and add another level to it, but its not returning what I would expect.

I need another set of eyes to look at the following. Instead of a Data Lookup table, I wanted to try to lookup a value against a Cache table that I had build. So I thought I could write a function to run a simple SQL query against the Cache Table and return me a %Boolean value back to my routing rule. However today I found that it was not working properly.

Can someone take a look at the following method and verify that I am doing this correct?

index = column name

value  = HL7 field that I am passing into the method

I would like to examine the contents of my OBX-5 field and not route the message if it contains alphabetic characters. I've tried various combinations of the Match and Contains functions, with no luck. Should I be using the COS ? operator or plaini regular expressions?

e.g.

OBX-5 Contains "\D"

OBX-5 Contains "?.A"

OBX-5 Contains "[A-Z]"

I am currently evaluating Source Control systems that we can use for both MS SQL, MS Visual Studio, and InterSystems IRIS. For both MS SQL and MS Visual Studio we do have the option of either Azure or GitHub.  I understand when we upgrade to IRIS 2019.1 we have options for Source Control, and in previous Global Summit's I have heard GitHub discussed.  So why can't I user GitHub for both MS SQL/MS Visual Studio and IRIS?

A couple of questions come to mind starting to think about Source Control

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

My Ensemble platform worked well before. 

Since yesterday , I found out lot of slow request ,I opened trace for one message. 

 

 

as above shown. 

It take about 8s from HisEmrRouter to ADTRoutingRule.

 In my opinion, HisEmrRouter And ADTRoutingRule is Simple Rule,  should't do IO operation. should be pure compute. 

Why does it take so long to process the routing?

Hi i have rules and i want to log them to analyse what rules executed , I want to add in the log Msg Controller Id, MRN, Value coming in the message, and my customize text telling whats wrong with this field... i have like 50 rules and at the end i can check the log table and found like 20 entries so it means 20 data issues are there for a given message control id. any advice how to to do it

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

Scott

Hi,

Business Rules can define a context object,  whose properties are exposed and used in the expressions of the rules. For example, my context object is an object with 3 properties. PropA, PropB and PropC.

When constructing my rules, I can call a custom function, and I have one I built myself called 'myFunction' which takes arguments and I pass in properties of my context object. (I can pass in the value of the context object's PropA, B or C).

Does anyone have experience in creating a Business Routing Rule using Exists function?

 

I've used the comma delimited 'In' function, but I would like more manageability. Entering and remove items from a look up table would be much easier to manage then changing the comma delimited string.

Messages go to error state.

In my Data Transformation, the Target class needs to create a new List of objects (ListOfObj), depending on some conditions of Source class (Source/Target are completely distinct/different classes).

I experimented with Lists of 'primitive' data types (ListOfDT), and I could add new %String items (as an example) to a List of %String property, with "append" action in DT.

Does anyone have an example, or guidance, how to create new Lists of Objects in data transformation?

For example, if I have a 'container' class like this, it works:
