Yale instructors from the course Addiction Treatment: Clinical Skills for Healthcare Providers walk through RIPTEAR, a structured framework for assessing patients with substance use disorders. The lesson uses a scripted case performed by actors to show clinicians how to move through each letter of the mnemonic, covering the types of substances used, prior treatment history, and the emotional and social context surrounding a patient's use. The goal is a complete, nonjudgmental picture that can guide next steps, whether that means screening for severity, building a treatment plan, or referring the patient to specialized services. The lesson is part of a Yale-produced training series, supported by SAMHSA funding, aimed at healthcare providers who need practical tools for addiction care rather than theoretical background. It treats addiction as a chronic, relapsing but treatable condition and frames the assessment as the first step toward evidence-based, compassionate treatment.
