Duration of anesthesia care provided for an operative procedure
We omit the cases whose Duration is > 36hrs or < 0
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 will calculate the difference in minutes between the Anesthesia Start and Anesthesia End Collations.
If the value returned is >36 hrs (>2160 minutes) or <0 (negative) the value returned is NULL.
