Created Variables Common 2021 table

The Created_Variables_Common_2021 table in CFE contains the values created by Created_Variables_Common_maker_2021 query. They are stored rather than generated on the fly because the query is slow for the volume of data involved (many minutes on Tina's PC) and because SAS can not read some data from queries. It is used by the statistician for reporting and data extracts.

Update to PatientFollow Project structure

1 I have made a new query created_variables_common_maker_2021 and corresponding table. I have populated the table with data for today, but not updated the calc created button yet because this is so slow that I don't want to run new AND old routinely. I have started to do comparisons, but so far all discrepancies I have found seem to stem from data errors. Emailed Julie and Pagasa about those. Aside from that, I am putting a copy of CFE with the new query and a populated Created_variables_common_2021 and old version to ::\\ad.wrha.mb.ca\WRHA\HSC\shared\MED\MED_CCMED\CCMDB\centralized_front_end\2021-created_test How do you want to test and proceed to using the new version? Ttenbergen 16:39, 2021 May 19 (CDT) I suppose you are changing the columns from adm to ER-delay, are these correct? are you just changing the data source from L_Log to tmp service or changing how to present the LOS - by record or by each service of each record? how about the transfer delay for MED involving High obs and regular ward where there are more than one legit transfer dates - are you including that in the calculation? I just changed the source from the L_Log values to the tmp values, where available, ie they would still be by profile. If we wanted them by service it could not really go onto Created Variables as it is right now, since it outputs one line per profile. I can make queries that e.g. do LOS per service, but those would have to be different queries that would have more than one line per profile, and we would need to define them before I can build them. Ttenbergen 15:10, 2021 June 3 (CDT) I need the rest for the ALERT Score in Medicine report - these have no change, right? The only things in CV common that I changed are the ones that use start times. Ttenbergen 15:10, 2021 June 3 (CDT) Ok to roll out since you have both the old and new in CFE. I will crosscheck the entries of LOS, transfer delay, ER wait once I have completed mine in SAS and will let you know. Thanks.---JMojica 10:22, 2021 May 20 (CDT) I have rolled the change. You will have to generate the output manually by running query created_variables_common_maker_2021. Ttenbergen 15:36, 2021 June 3 (CDT)

Background

Replacement for the old Created Variables Common table to deal with process changes such as PatientFollow Project. A new table/query was set up instead of modifying the old one in order to allow for testing over a period of time.

• to do:
  • change Age to use first service dttm instead of (Accept_DtTm if available, Arrive_DtTm otherwise)
  • adm - (Accept_DtTm if available, Arrive_DtTm otherwise)
  • trans - Transfer Ready DtTm, included because used to be calculated
  • dis - Dispo DtTm, included because used to be calculated
  • Transfer Delay
  • ER Delay
  • Glasgow Coma Scale
