PACU End Time

Description

This phenotype is used to determine the time when the patient left the Post-Anesthesia Care Unit (PACU).

Limitation

Accuracy of this phenotype is dependent on accuracy of EHR documentation and limited by criteria available on a given case.

Cases where the latest documented PACU Concept is >6 hours but <12 hours after anesthesia end, PACU End will default to 'anesthesia end + 6 hours'. Any PACU concept documented before anesthesia start or > 12 hours after anesthesia end will not be considered. Standard extract for the data is set to 6 hours post-anesthesia end which is why this time was selected, cases may have data outside of these ranges.

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

PACU End Time is determined by returning the timestamp of the following criteria. This phenotype only considers the criteria if documented after Anesthesia Start and <12 hours after Anesthesia End:

Use the latest documented PACU concept below if documented <12 hours after anesthesia end. If time of latest concept below is >6 hours and <12 hours after anesthesia end, then return time of ‘anesthesia end + 6 hours’.
