It's is calculated by Created_Variables_Common_maker_2021 query and stored in Created_Variables_Common_2021 table in CFE. It is related to one of our Indicators, Length_of_Time_for_Transfer_from_ED_to_ICU_within_same_facility.

Data use

• Measure the time spent using ER bed/facilities/staff while already accepted under a Medicine or Critical Care Service.
• Measure the delay of movement of patient from ER bed to Medicine or Critical Care bed.

ER Delay Calculation

• Before Oct 2020 : If Previous Location is own ER
  • Non-EMIP / Non-ECIP : Arrive DtTm - Accept DtTm and Accept DtTm missing is not marked
    • if Accept DtTm missing is marked then ER Delay is missing.
  • EMIP/ECIP: Dispo DtTm - Accept DtTm
• Starting Oct 2020 : if first Boarding Loc is own ER
  • Only one ER Boarding Loc: Dispo DtTm - first ER Boarding Loc start Dttm
  • At least two Boarding Loc: First NonER Boarding Loc start Dttm - first ER Boarding Loc start Dttm

Implemented as

ER_Delay:

IIf(Not [PatientFollow],

IIf([location_name] Like "*EMIP*",[Dispo_DtTm],[Arrive_DtTm])-Nz([Accept_dttm],

[Arrive_dttm]),Nz([created_FirstNonER_BoardingLoc].[dttm],[Dispo_DtTm])-[created_FirstER_BoardingLoc].[dttm])

This data is problematic before 2011-Q2,the only reason there are any is because it derives them for EMIPs. Some data may be available in Moves for Medicine, but that would still leave a gap. Ttenbergen 23:09, 2024 November 16 (CST)

Log

I have re-updated Created_Variables_Common_maker_2021 query, for some reason the change I had made was not reflected in the master version. Ready to test. Ttenbergen 13:25, 2022 June 28 (CDT) emailed Tina some inconsistencies found in ER Delays Aug 15,2022. --JMojica 13:21, 2022 August 29 (CDT) are these still an issue? Ttenbergen 11:15, 2024 May 1 (CDT) I will re-check again. Can't remember if have been resolved. --JMojica 14:40, 2024 October 2 (CDT)

• 2022-06-28 - previous change got lost somehow, re-applied it; updated query to use query created_PatientFollow rather than in-query definition
• 2022-06-09 - updated Created_Variables_Common_maker_2021 query with the new definition.

Reporting and Analysis

The SAS Program to read the data is in X:\Julie\SAS_CFE\CFE_macros\datetimes.sas

I just had a look at that sas file (they open as text files) to see how you define transfer delay. If that file is still being used we may have a problem, it still defines tdelay different if a pt goes to a higher level of care, goes AMA or dies, and we changed that some time ago. So is this still the reference of how you calculate this? Ttenbergen 22:50, 2024 November 16 (CST)

Legacy

• Used to be just the difference between the Accept DtTm and Arrive_DtTm for patients arriving from the ER.
• Used to be collected as ER Wait and before that as Moves for Medicine.
