Description

This phenotype is used to determine if any haolgenated gases were used during a case

Limitation

Note these readings do not have to be consecutive or of the same type of halogenated agent.

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 determines if a halogenated anesthetic was administered between Anesthesia Start and Anesthesia End.

A case must have = 2 halogenated gas physiologic values above threshold for = 2 minutes to return (1) Yes. If < 2 valid halogenated gas values between Anesthesia start - End then, (0) No, halogenated gas was not used during the case. Missing minutes between valid values will have the last value carried forward if <= to 5 minutes.

*Note:

These readings do not have to be consecutive or of the same type of volatile gas.
