Design outcomes

Primary

MeasureTime frameDescription
Prevalence of cannabis withdrawalUp to 1 yearDescriptive statistics will be utilized to summarize cannabis withdrawal prevalence.
Severity of withdrawal symptomsDaily for first 4 days of hospitalizationAssessed by the Cannabis Withdrawal Scale (CWS), a self-report instrument used measures the intensity of 19 cannabis withdrawal symptoms over the last 24 hours. Each item is rated on a 10-point Likert scale where 0=not al all and 10=extremely. Items are rated twice, first for intensity of symptom and then for negative impact on daily activity. Withdrawal symptom scores range from 0 to 190, with higher scores reflecting greater intensity of withdrawal symptoms.

Secondary

MeasureTime frameDescription
Mortality RateUp to 1 yearAssessed for all-cause, in-hospital, and post-hospitalization mortality rates by review of the electronic medical record.
