PEEP Set Median

Description

This phenotype determines the median PEEP value for all set PEEP values captured between Case Start and Case End.

Limitation

Only values mapped to MPOG concept 3212 Positive End Expiratory Pressure - Set will be considered for this phenotype. Case start and case end times are determined using additional MPOG logic- please reference those phenotypes specifications for more details on limitations.

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.

Logic

This phenotype returns the median value for positive end expiratory pressure (PEEP) using set PEEP values mapped to MPOG concept 3212 Positive End Expiratory Pressure- Set. Only values captured between case start and case end are included in determining the median value.

The PEEPSet phenotype is used to determine the list of starting PEEP values for calculating the median PEEP set value.

Documented dates before January 1, 1995 will not be included.
