Topic: No corresponding code for ventilator waveform data
Andy Pham (Dec 03 2018 at 08:44):
Hello,
I am trying to map ventilator waveform data to the Observation resource and am currently using the LOINC Rosetta respiratory panel codes to code for pressure waveform data. My data consists of pressure measurements recorded during both inspiratory and expiratory phases. However, the LOINC codes only cover pressure during inspiration and during respiratory pause and not expiration and I cannot seem to find a corresponding code anywhere else for that kind of data. Since the code field is required to implement Observation resources in FHIR, what would my options be? Would I have to create my own controlled vocabulary or something?
Thank you!

The ISO/IEEE 11073-10101a nomenclature has a very complete set of terms for respiration, spirometry, pulmonary mechanics, ventilators and anesthesia machines, including waveforms. This information should (or will be soon) available from the NIST RTTMS (talk to John Rhoads) as a FHIR vocabulary resource. For now, you can download the entire set of -10101a nomenclature tables from the IEEE-SA download and executables site at https://standards.ieee.org/downloads.html (at no charge or need for a password). Once you're there, click on the -10101a zip file to download (the vocabulary tables that you are looking are in the large HTML file). Examples of identifiers that are used for waveforms include MDC_FLOW_AWAY, MDC_VOL_AWAY, MDC_PRESS_AWAY, MDC_CONC_AWAY_CO2 and others. Best regards, Paul Schluter

@Paul Schluter , can we get the Rosetta valuesets and terminology mapping into FHIR form? This is not a hit against the IEEE format, but rather indication that many have found the FHIR terminology mechanisms to be handy. DICOM vocabulary is available in this form. IHE vocabulary is available. It is just a format thing. @Grahame Grieve a possible R5 task?
Grahame Grieve (Dec 03 2018 at 23:25):
doesn't have to wait for R5, but it's supposed to be already done or in progress
Paul Schluter (Dec 03 2018 at 23:31):
Please contact John Rhoads john.rhoads@philips.com or Nicolas Crouzier nicolas.crouzier@nist.gov for the current status. Providing FHIR access to the 11073 vocabulary hosted on the NIST RTMMS is reasonably far along. Best regards, Paul Schluter

I've been traveling today mostly without internet access and I'm just now seeing this. Sounds like @Paul Schluter 's suggestions regarding 11073-10101a should likely work for @Andy Pham? If we can move ahead and have these available via a FHIR terminology service that will be great.
Andy Pham (Dec 04 2018 at 02:33):
Yes the 11073-10101a nomenclature will work fine for the purposes of my task, thank you so much to everyone who helped!

Definition of the FHIR code system for ISO/IEEE 11073-10101 Nomenclature is available here. There is still work to do for providing these codes through the FHIR terminology servers.
John Rhoads (Dec 04 2018 at 21:23):
We are working with NIST to make the lifecycle codes matching the standard available in the data feed. They are very busy with IHE testing tasks, but it should be done "real soon now"
Daniel Vreeman (Dec 13 2018 at 11:58):
There is a mapping table of all the IEEE 10101a terms to LOINC codes maintained jointly by Regenstrief and IEEE that we publish as a FHIR ConceptMap resource here: https://fhir.loinc.org/ConceptMap/?url=http://loinc.org/cm/loinc-to-ieee-device-codes If you could be more specific about the expiration variables you're looking for we might point you in the right direction, or if you want to make a new LOINC term request, there's an open channel: https://loinc.org/submissions/ P.S. All of the LOINC content available in FHIR terminology services as part of the standard LOINC release process is described here https://loinc.org/fhir/
