This query checks for some scenarios around intubation that are possible, but are entered erroneously often enough to make it worth warning about them. It is implemented as a soft check, so collectors can click past it.

Could happen in case of Tracheostomy creation in procedure suite

There might be no extubation if pt has a trach (T23 - Trach Tube Present (TISS Item)) created (Tracheostomy creation), since that would be done in OR and part of it would be the extubation. Since this would be a soft check, the collector could just OK past it if this is the case.

The check

intubation or extubation

ETT or ventilation


Another scenario:

  • yesterday I have ETT
  • today you t40 new insertion marked,
  • but there is no extubation either yesterday or today

Another scenario:

  • ett2 not null
  • intub3 not null
  • extub2 null
  • extub3 null

Another scenario

  • new insertion today
  • tomorrow there is no ETT present
  • there needs to be an extub present today


  • 2022-08-11 - tweaked the query to only run 1000 days back and to not include future dates (for a long-LOS pt the query was giving error "The query cannot be completed. Either the size of the query result is larger than the maximum size of a database (2GB), or there is not enough temporary storage space on the disk to store the query result.")
  • 2022-02-09 - updated to broaden criteria 3 to not require ett3 to be any specific value; added criteria 5
  • 2022-01-11 - updated to link days by Pat_ID properly
  • 2022-01-10 - updated to work right with param parameter
  • 2022-01-06 - activated as soft check
  • 2021-11-10 - implemented query but not calling it from code yet, want Lisa or someone to check on this
