NHSN Feed

Hi, 

We received a large batch of messages through NHSN's AIMS feed that have no value in MSH.4.1, which has the facility code. We are not able to process these messages without a value in MSH.4.1. Did any other jurisdiction have this problem today? Not sure if this is an issue on the facility side or the AIMS/NHSN sender side. Any help is appreciated! Thank you!

Virginia has the same issue.

NJ logged an AIMS support issue about this - we are looking into it

Thanks Riki. Minnesota is also experiencing the same issue.

Do we have any update on this? We are continuing to get messages from NHSN that have no MSH.4.1. Thanks!

Yes - NHSN updated their production feed - they now have the namespace ID in the dB, so they can provide it ahead of time (and are working on an updated spreadsheet for us to share), but that must have caused the hick-up in the code... I was under the impression they stopped the feed. They are releasing a patch today and hope to be back on-line tomorrow.

Riki,

Is there a way to get a list of facilities/labs that are currently reporting through AIMS?

As far as I know only what is on the COVID Centralized ELR reporters list here: https://app.smartsheet.com/b/publish?EQBCT=6a622ae0402147fd90aac0f3a527642f
The only other way I know would be to see the list of sending jurisdictions (but that would only give you NHSN or eTrue North, not all the facilities. I don't think AIMS tracks all the performing organizations (in OBX-23).

Actually, that is really helpful, Riki.
I did not know that we had access to that smartsheet. I’m sure I missed it along the way.

Thank you very much!

Hi all - this is NOT related to the MSH-4 issue, BUT to NHSN feed in general.
There were issues with duplicate MSH-10 values, for messages where facilities had made corrections close enough together that they were processed in the same batch.
Here are 2 things that came from this error:
#1: NHSN will push a change out that adds 6 random numbers to the end of their MSH-10, which is currently following this schema: [oid + specimen id + current timestamp in milliseconds]  - that will be rolled out as soon as possible for a new schema to be: [oid + specimen id + current timestamp in milliseconds + 6 character random string] 
#2: Dealing with corrections: For many PHAs it is an issue when a record is sent as corrected, when the actual result value did not change, since many PHAs do not incorporate negatives into their surveillance system, unless they are a correction to a positive result (but in most cases that is not the case in these instances).
So we want to know if it would help the states if we could, at a file level, batch the positives (P), negatives (N) and corrected (C)? 
So, right now we send:
Facility1234.hl7
Facility4567.hl7
 
What if we sent:
Facility1234-P.hl7
Facility1234-N.hl7
Facility1234-C.hl7
 
Facility4567-P.hl7
Facility4567-N.hl7
Facility4567-C.hl7
 
or
 
Facility1234-P-C.hl7
Facility1234-N.hl7
 
Facility4567-P-C.hl7
Facility4567-N.hl7

Any feedback by EOD today would be appreciaed, as NHSN is trying to get this fix out ASAP.
Walter Kemper, ELR Coordinator, NC DHHS Div of Public Health
That would be OK for NC.

How would we differentiate real corrected negatives from those that are being triggered off something other than the result? We want to be able to receive updates if a lab enters a test result incorrectly as positive when it was truly negative.

The file splitting is fine for Ohio but not sure how that will help the problem other than giving the states the choice to decide if they will use corrected results or not. Can AIMS deliver different files to different paths to the same jurisdiction?

Hi Rikki,
Sorry I didn't see this earlier. I'm cc'ing Can for his feedback.
