Discussion

Just came across this... the started query includes additional dxs now, as per #CCI collect count each. Does the proposed accepted count make sense for all the dxs? Your validation table was for CXR. Ttenbergen 11:50, 2023 May 3 (CDT) Did some checking on all 13 LAB Imaging from CCI picklist and found counts more than the LOS only in ECHO, AXR and CXR. Emailed Lisa and Pagasa March 14, 2024 to check if correct or not. Waiting for their feedbacks. In the email, I also propose another query (e.g. the counts per calendar day per patient must not be more than one) as alternative to the threshold limits LOS +- 3 STD shown below. --JMojica 10:55, 2024 March 18 (CDT) That query is tighter and would therefore have more false positives. What does Lisa think about that? Ttenbergen 09:51, 2024 March 20 (CDT) I made some limits per LOS group for CXR, AXR, ECHO and Blood gases and emailed the results to Tina and Lisa 3/25/2024 for discussion. ---JMojica 13:28, 2024 March 25 (CDT) Further emails with Julie and Lisa about details. Discussed with Lisa who is reviewing some of the errors and will hold off until she is done. Ttenbergen 12:46, 2024 April 8 (CDT)

We will set up a query that checks LOS <7 and count >10 (i.e. double digits) Julie will provide the list of checks for which this should trigger by email to Lisa and Tina this check will change names because it's for more than one test now

We have had some medical Category:Labs Imaging count entries that are so high that they are likely errors.

What are likely maximum entries?

The count per patient stay is related to the LOS. The threshold limits are either Mean + 3 Standard Deviation or Maximum value of Chest X-ray count per patient day for various LOS category listed in the table below. They are derived from July 1988 to June 2017 Lab data. The LOS is based on calendar dates where partial stay is considered as full day.

• LOS based on calendar dates = Function LOS() + 1
  • if patient is still in the unit, Dispo DtTm is replaced by today's date
    • check is marked as only running on complete records, if that is so then we don't need to replace with today's date
• Chest X-ray (CXR) per patient day = Number of chest X-rays / LOS Based on calendar dates

CCMDB.accdb cross checks triggering for correct values

If the actual correct data leads to a cross-check error CCMDB.accdb will not allow you to send. In that case, enter a value that is acceptable and then email the Data Processor using the "generate email" button.

Checks

This uses Function LOS() to calculate the LOS.

CCI collect count each

• AXR (abdominal plain X-ray) 3.OT.10.VA
• Blood gas, arterial 2.ZZ.13.RE
• Blood gas, venous 2.ZZ.13.RA
• CXR (plain film) 3.GY.10.VA

"CCI collect count each" count should not be higher than:

• if LOS < 1, 5
• if LOS 1-50, LOS * 2
• if LOS > 50, LOS

CCI collect count days

"CCI collect count days" should not be higher than LOS. See query check_CCI_vs_LOS_count_days_component and query check_CCI_vs_LOS_count_days_picklist.

CCI collect count units

Discussed with Julie that this one is likely uncheckable. Ttenbergen 15:47, 2021 September 2 (CDT)

CCI collect each

Discussed with Julie and no specific checks required for this one.

Log

• 2022-02-10 - confirmed that this would not be affected by the change of including a time in the Px Date
• 2022-01-19 - Julie confirmed that we don't need to check this per Boarding Loc - per profile is enough (especially since it's a soft check)
