Descriptive statistics based on an aggregate patient cohort (N = 9153), drawn from seven CNICS care sites.
SUD identification based on substance-specific diagnostic thresholds from both the AUDIT-C and ASSIST, with six subgroups defined as: 1) opioid UD with or without other SUD, 2) methamphetamine UD with or without other SUD, 3) alcohol UD with or without other SUD, 4) cocaine UD with or without other SUD, 5) marijuana UD only, and 6) no SUD.
Retention indices based on 24-month clinic visit documentation, as follows: visit-constancy was the number of four-month intervals with an attended visit; care gaps were the number of six-month intervals without an attended visit; visit adherence computed as [attended visits / (attended visits + ‘no-shows’)].
