Modelling bladder scan / post-void residual volume

Clinical
1

Hi all,

We’re looking into modelling bladder scan results, in particular bladder volume / post-void residual (PVR) volume, in openEHR.

I’ve searched CKM and Discourse but haven’t found an archetype specifically intended for this use case. I did find openEHR-EHR-CLUSTER.imaging_exam-bladder.v0 (“Imaging examination of the bladder”), which contains bladder dimensions (length, width and depth), but doesn’t appear to contain bladder volume or post-void residual volume.

Before we start modelling something ourselves, I’m curious whether anyone has already looked into this.

Has anyone implemented or modelled bladder scan results / post-void residual volume in openEHR? If so, which archetypes and modelling approach did you use?

I’m also interested if anyone has considered this use case previously, even if it hasn’t made its way into the CKM.

Thanks!

Hi, I remember participating in the prostate MR template modeling (not quite the same use case, I know), but the Physical dimensions cluster was used there to represent volume.

Hi Mattijs! We’re working on similar models as well. I’ll get back to you about details soon!

Sorry for the slow follow up!

We’ve made some design notes available here: archetypes-wip/doc/bladder-voiding/README.md - codeberg.org/openehr-no

Feel free to make comments and/or suggestions :smile:

Heya @siljelb ! I heard you got in touch with my team at the EHRCON about this subject.

Shall we organise a video call to see if we can get these preliminary designs to reviewable CKM-archetypes?

Sure, would you or someone else run a poll to find the least worst time?

Anyone else who wants to participate, this is probably a good time to put your hand up :woman_raising_hand:

I’ve responded, assuming the time zone is CEST(?).

In an international community like this it’s generally a good idea to use polling tools that take time zones into account. I’ve had good experiences with https://rallly.co lately.

Hi. I would like to joint the meeting. I’ve been working on a urinary incontinence diary, and we may have some overlapping needs.

I have closed the poll and reserved thursday 22nd october 15.00-16.00 (CEST) for the online meeting.

You can send me your mail on michiel.klitsie@nedap.com, and I’ll add you to the invite. Other option is to add the teams-meeting below to your own agenda :slight_smile:
