Arterial Line Used

Description

To identify cases that have at least 20 valid blood pressure values taken from an invasive arterial line.

Limitation

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 collation checks for the following invasive blood pressure physiologic concepts:

3013 - Invasive Unspecified Site 1

3043 - Invasive Unspecified Site 2

3040 - Arterial Line (Invasive, Peripheral)

The phenotype will only consider blood pressure values up to 2 hours before anesthesia start (MPOG Concept ID: 50002) and up to anesthesia end (MPOG Concept ID:50009).

If there are >= 20 total valid blood pressure values for one of the invasive blood pressure concepts, then return a 1 for "yes."

Else, if there are more than 0 values but less than 20 total values, return 2 for "Inconclusive (< 20 observations)."

If either concept, Monitoring - Arterial Line Placed (MPOG Concept ID: 50222) or Procedures - Arterial Line Placed (MPOG Concept ID: 50662) and the case has 20 <= 1 minute-to-minute blood pressure 'Non-invasive concepts' (MPOG Concept ID: 3015; 3020; 3025) used, return 3 for "Inconclusive (arterial line concept used with >= 20 NIBP readings)." The timeframe for the Artline placed concepts will be considered up to 2 hours before anesthesia start until anesthesia end. If the observed time is not present for blood pressure concepts or the arterial line placed notes, the phenotype will consider entered times.

Else, return a 0 for "no."
