The ER Delay is the difference between the pre-ER Boarding Loc and first post-ER Boarding Loc, for patients arriving from the ER.

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

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])

  • 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.
