Motion Sickness History Classification

Search:

Description

This phenotype determines if the case has preoperative documentation to support a history of motion sickness. Collation mapping is performed to categorize raw text values found in the electronic medical record and mapped to specified preoperative MPOG concepts (see logic section for more information). Collation mapping is performed at the MPOG Coordinating Center.

Limitation

Collation mapping relies on both predictive analytics and manual mapping of raw values to appropriate categories. Only variables mapped to designated concepts and including key words such as motion sick will be assessed. The entire record is not reviewed to determine history of motion sickness.

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 creates a list of notes based on keywords found in the values associated with variables mapped to specific MPOG concepts. Those notes are then collation mapped at the MPOG Coordinating Center using predictive analytics and then validated by an MPOG internal reviewer. The list of notes for mapping is created using the following steps:

The collation adds raw text & numeric values for variables mapped to MPOG concept 70102 Misc - Motion Sickness
Then, the collation adds raw text & numeric values for variables mapped to any of the following concepts that include the keyword 'motion sick' in the note itself or the comment associated with the note:
1. 70080 General – Previous Anesthetic Problem
2. 70140 General - Past Medical History ICD-9 Code
3. 70141 General - Past Medical History ICD-10 Code
4. 70225 Assessment and Plan – Comments
5. 70263 Physical Exam - Other Comments
6. 70302 Assessment and Plan - Anesthetic Consideration
7. 70338 General - PONV Risk Factors
8. 70413 General - Past Medical History (not categorized)

If the case has multiple values assigned for a single case, the following logic will be applied to determine a single value for the case:

If History of Motion Sickness (1) is included, assign 1: History of motion sickness.
If No history of Motion Sickness (0) is included without 1, assign 0: No History of Motion Sickness.
If Invalid (-998) is included without 0 or 1, assign -998: Invalid.
Else, assign -999 Missing or Unknown
