Anesthesia start time/date for a procedure/case
This phenotype uses note concept ID 50002 (AACD Anesthesia Start Date/Time) to define the anesthesia start time. Those defined outside this concept will not be captured.
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 uses note concept ID 50002 (AACD Anesthesia Start Date/Time) and returns the associated time observed for the variable mapped to the AACD Anesthesia Start Date/Time concept. If there are more than one anesthesia start times for the case, this phenotype will result the earliest time.
