#Business Rules

4

Business rules are the part of InterSystems Ensemble production solution which allow nontechnical users to change the behavior of Ensemble business processes at specific decision points.

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 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.

I am trying to create a rule which filters out ADT_A08 messages, when they have an OBX segment and their EVN.4 is "COD" or EVN.4 is "FIN"

The attempt is:

I have sent messages with EVN.4 COD or FIN and they are filtered out correctly

However if I remove EVN.4 and leave just the OBX filled up, the message passes from the Process to the Operation.

We have a case where we have 1 message coming in, but then sending two messages out to the same location. Even with FIFO sometimes the messages get out of sequence depending on what is need to be done to the message in the DTL before send. Is it possible to call sleep or Halt or write some kind of a function to put a pause in a routing rule between two sends?

Filter by time in Routing Rule

I have a colleague that is trying to eliminate any HL7 transactions that have admit date/time of midnight from going to an downstream system within a routing rule. I have tried several different iterations of code trying to figure this out just in the routing editor. Without having to write an object script function is this possible?

Conditions within ruleset

Hi guys

I have always struggled with this, tended to use workarounds but now decided to hear from more experienced people if this is something I am misunderstanding.

I need to basically add a "send" within the ruleset number 2, but without a need to associate a "when" node to it. Is this possible? What I basically need is to forward messages with status 160 to "ManageEDM" and also regardless of the status, it should get sent to "ManageRIS"
