Cardiopulmonary Bypass End

Description

This phenotype returns the latest date/time of cardiopulmonary bypass specific concepts for each case.

Limitation

Does NOT capture undocumented partial/left heart cardiopulmonary bypass (if NOT documented in notes, otherwise DOES capture)
Does NOT capture VA/VV bypass (these are separate concepts) à e.g. for ECMO, liver transplant, or IVC thrombectomy Only gets first start, and last end
Only captures first start and last end, thus multiple CPB runs will return as one consecutive run.
This group returns the time of the first instance and last instance, regardless of the type of the specific cardiopulmonary bypass (CPB) trigger. Thus, if a case has documented 50426 (Ice off head) twice, and only these CPB concepts, this phenotype will return the first and last instance of documentation and the duration in between for the documentation.

Data quality is limited to individual site documentation accuracy, completeness, and variable mapping, which is performed by each site, independently. MPOG, as the coordinating center, reviews data quality at each data upload and monthly via Data Diagnostics and Case Validation tools. This review, while thorough, may not contain all data elements relevant to this phenotype and thus should be carefully reviewed by the user.

This phenotype returns the latest date/time of the concepts listed below per case. Only considers notes documented between Anesthesia Start and Anesthesia End

For intraoperative notes, the following concepts are used:

50409 Cardiopulmonary bypass terminated
50767 Cardiopulmonary bypass -- Circulatory arrest stop
50422 Cardiopulmonary bypass -- Arterial cannula insertion site detail
50410 Cardiopulmonary bypass initiated (full)
50415 Cardiopulmonary bypass -- aortic crossclamp off
50714 Cardiopulmonary bypass - Bypass start / stop event
50421 Cardiopulmonary bypass -- Arterial cannula inserted note
50426 Cardiopulmonary bypass -- Ice off head
50047 Perfusion - Retrograde Arterial Prime/Venous Antegrade Prime Performed (Yes/No)
50346 Vascular - Aortic cross clamp on**

**This concept is used for vascular cases, but often to mark cardiac bypass start as well.

If none of the concepts are in the case, then the case will not be included in the results of the collation.
