Substance Use Disorders (SUDs) are serious health conditions which can significantly impact a patient’s physical and mental health. Appropriate screening allows physicians to identify substance use problems early, enabling them to offer interventions and treatment to prevent or reduce harm. Early identification and intervention can also minimize the risk of fatal and non-fatal overdoses and potentially reduce the high healthcare costs associated with untreated SUDs. This CME training course focuses on equipping healthcare professionals with the knowledge and skills needed to effectively screen and diagnose substance use disorders (SUDs). Participants will learn about validated screening tools, risk factors, diagnostic criteria (including DSM-5), and evidence-based treatment approaches for individuals with SUDs.
