Description
Binary variable indicating whether a case meets the Intraoperative Research Standard as defined in the Logic section below.
Limitation
This phenotype relies on several other phenotypes, which each have their own limitations.
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
Each case must meet eight (8) criteria to be classified as a Yes for this phenotype:
- Has valid Anesthesia Start and End – phenotypes for Anesthesia Start and Anesthesia End must both exist, must both not be null, and Anesthesia End must occur after Anesthesia Start.
- Patient in Room time should be valid if exists – exclude only cases where Patient in Room Date/Time occurs more than 30 minutes before Anesthesia Start. All cases where Patient in Room Date/Time does not exist, occurs after Anesthesia Start, or occurs 30 minutes or less before Anesthesia Start are included.
- Anesthesia Duration
- For General Anesthesia Cases (where the Anesthesia Technique: General phenotype is 1-6, inclusive), include all cases where Anesthesia Duration is at least 10 minutes.
- For Non-General Anesthesia Cases (where the Anesthesia Technique: Generalphenotype = 0), include all cases where Anesthesia Duration is at least 5 minutes.
- Age must be present – Age (Years) phenotype must not be Null.
- Sex must not be unknown – Sex phenotype must not be Unknown.
- ASA Class must not be missing, invalid, or conflicting – ASA Class phenotype must be 1-6, inclusive.
- At least one valid BP value must be present – at least one non-artifact blood pressure measure exists within the Blood Pressure Observations phenotype.
- At least one intraoperative medication was administered – At least one medication listed in the AIMS_IntraopMedications table.
