Hi @akanter, I would like to ask your advice on how we should proceed with setting Vital Sign ranges for the O3 RefApp.
Currently, we are using CIEL concepts for the vital signs in O3 (SBP/DBP, Pulse, SpO2, RR, etc).
However, these CIEL concepts don’t have complete ranges. We’d like folks to easily see that visual alerts are triggered if concerning vitals are recorded, but this is not triggering right now because I cannot set the ranges on CIEL concepts. Since some implementations will likely copy our distro, I would also very much like our config to be a wise starter-kit - and that includes the Vitals ranges.
How do you recommend we proceed? Should we:
A) Manually copy/re-create the CIEL concepts for Vitals, so we can customize the ranges ourselves? (Obvs we would map to the original CIEL concept)
B) Wait for range changes in the CIEL concepts themselves? (Assuming CIEL is willing to appoint sample regerence ranges to existing Vitals concepts, and assuming this would not create breaking issues for other implementations)
Once again, this is a great example of the need for Curated Concept Customization (CC @jamlung & @paynejd)
Totally agree that these customizations would be non-breaking changes. I just had a conversation with EthiOHRI about cloning as I had thought that the OpenMRS Dictionary Manager actually allowed customization of cloned concepts. However, they said that cloning is not working.
In this case, I think that I could add ranges if it makes the RefApp work. Alternatively, one could copy the CIEL concepts with SAME-AS maps to CIEL as you suggest. We need a way as @burke has described to relink historical SAME-AS maps in his life of a concept planning.
As long as the reference ranges are not absolute, I think it probably would be OK to add them. I am working on a release now (Mpox from Monkeypox and others) so let me know ASAP.
I’d suggest adding absolute ranges. As long as we’re defining ranges, let’s not ignore absolute ranges. My suggestions would be 0-400 for pressures, 0-500 for pulse, abs low of 0 for resp, 0-100 for SpO2, and 0-50 for temp) to help prevent nonsensical data. An absolute max resp rate is probably not worth setting, since there can be exceptional cases (like high frequency ventilation of neonates) where resp rate can be in the 100s.
FYI - the phrases like “12 and below” in your spreadsheet are misleading, since low & high define inclusive ranges. For example, a “Normal Low” of 12 for resp rate means 12 is normal. Any value below 12 (down to & including the critical low value of 10) would be abnormal and values below (but not including 10) would be critical.
Hi @akanter, thanks so much for adding these reference ranges in last year I have an update request from a physician funder/supporter, who’s asking if we can make these changes:
"HR normal low should start at 59, not 60.
Temp normal low should be 35.5, and temp critical low should be 34.5"
Both of these make sense to me, especially the HR adjustment; I realize now I’d be annoyed if the EMR was alerting me for a “normal low” of 60. Do they sound clinically prudent to you?
I also like @burke’s suggestion of the Absolute Ranges, although I suggest 60C for Temp high because highest recorded temp has been >46 C; may as well round to a high but not blocking number (I’m reminded of cases where we’ve had to change our absolute highs because of remarkable clinical cases, like extreme reported age). Same logic for Pulse at 600; since one article states highest tachy on record was 480. May as well round high enough so not to be prohibitive.
The normal range is from low_normal to hi_normal, inclusive, so a pulse of 60 would be normal with low_normal of 60. Your spreadsheet is misleading, because, for example, a phrase like “60 and below” describes what is outside of normal instead of the lowest value of the normal range (i.e., low_normal).
So how does the app respond? If normal low is 60, then 60 should not throw an alert. I will not make any changes until I get a firm recommendation… I am working on the ANC DAK maps but could put out a new release this weekend if Burke is up for it.
