Intubation Time

Description

This phenotype returns the earliest date/time of ETT or LMA placement documented between Anesthesia Start and Procedure Start.

Limitation

This phenotype is limited to a subset of airway placement MPOG concepts. AIMS variables mapped to concepts outside of this subset are not considered.

To be defined as an ETT and/or LMA note, cases must have an ETT or LMA note plus another ETT, LMA, or General note for the case. Tracheostomies are often not found with this phenotype, unless it was exchanged for an ETT at some point of the case.

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 earliest airway placement note documented between Anesthesia Start and Surgery Start.

If Surgery start is not available then,

Surgery End. If not, then

Patient out of room. If not, then

Anesthesia End.
