42 had pre-op alcohol abuse; 16 had pre-op alcohol dependence
7 had post-op alcohol dependence
3 had pre-op and post-op alcohol abuse; 6 had pre-op and post-op alcohol dependence
Alcohol Use Disorder (AUD) status for the SCID was recoded from “no” to “yes” if the AUDIT data indicated AUD. Because the AUDIT only assesses the past 12 months, data was set to missing if AUDIT data from pre-op, 1, 2, or 3 years was incomplete, and pre-op status was only updated based on the 12 months prior to surgery.
7 had indication of AUD in the 12 months pre-op (AUDIT), whereas 12 did not, but had indication of AUD pre-op (SCID).
