Smoking Status

This template represents a patient's smoking status. It is a combination and replacement of the two previous templates Smoking Status - Meaningful Use and Tobacco Use, and it aligns with the US Core Smoking Status profile.

When the code represents a quantifiable observation (such as Cigarette pack-years - 401201003), the value may be a Physical Quantity. When the code is Smoking Status (72166-2) or Tobacco Use (11367-0), the value SHALL be coded.

Regarding effectiveTime: some values in the Tobacco Use value set represent temporal meanings (e.g. 266919005 - Never smoked tobacco) and should correspond to a single timestamp representing when the observation was true. Other codes, such as 59978006 - Cigar smoker, may be represented with a single timestamp or a time range indicating when the patient began smoking and when they stopped.
