Smoking Tobacco Classification (new)

Search:

Description

Classification to determine non-smoker, former smoker, or current smoker. This collation only considers tobacco smoking status, not marijuana or other substances. Use of smokeless tobacco products, including chewing tobacco, are classified as ‘non-smoker.’ Smokeless tobacco products are classified in a separate phenotype.

Limitation

This collation relies upon the SmokingTobaccoNotes collation which utilizes mapping to one of the concepts listed in the logic section.

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

‘Current smoker’ is assigned if there is documentation of smoking tobacco within 30 days prior to the procedure. ‘Former smoker’ is assigned if there is documentation of a quit date >30 days prior to the procedure.

Current logic for smoking classification (combining individual note values from the SmokingTobaccoNotes collation, there may be multiple notes per case). The SmokingTobaccoNotes collation returns a value for each note. The Smoking Tobacco Classification phenotype then determines if there is a note which falls into the CurrentSmoker, NonSmoker, and FormerSmoker and will apply the following logic:

Use the latest smoking status documented before Anesthesia End
If there are multiple, conflicting smoking notes documented at the same time, apply the below hierarchy in this order:
- If any of these concepts are documented at the same time, determine status according to this hierarchy:

70160 History-Social History-Tobacco (current smoker)
70161 History-Social History-Tobacco (former smoker)
70162 History-social history-Tobacco (non-smoker)

For all other concepts, determine status based on this hierarchy:

Current Smoker
Former Smoker
Non-Smoker
Unknown
Invalid
Unmapped

If no smoking notes, return -999 "Unknown"
If collation mapped to missing or unknown, return -999 "Unknown"
If concept not collation mapped, return "Unmapped"
Only return -998 "Invalid" if collation mapped to invalid and no other smoking concepts are mapped (even if invalid value is closest to anesthesia start)
