 Those in the BI arm will be asked by the research staff to show and discussed with the clinicians their screening results. The clinician will deliver the BI for alcohol use reaching moderate or high risk level from the ASSIST as well as advice to stop the consumption of harmful levels of any substances reported by the patient. The BI should include discussion of risky level of alcohol consumption, associated adverse effects, and followed the adapted ASSIST BI steps for Kenya, which include asking the patient to come back for follow-up about a month after the BI. Clinicians will record their baseline and follow-up clinical assessment and management through clinical follow-up forms. The total BI should be around 15 minutes, with a follow-up visit of about the same length. Any further follow-up will be at the discretion of the clinician, as part of on-going PHC.
