The book lends particular attention to the identification and stabilization of high risk medical conditions associated with each substance of abuse. The second section is psychiatrically focused, addressing the most common psychiatric symptoms and syndromes, their association with SUDs, an approach to differential diagnosis, and discussion of crucial treatment considerations for both safe ED management and post-ED disposition. A final section includes other pertinent topics, for example, the assessment of patient safety, responding to the medication-seeking patient, assessment and treatment of pregnant patients and working with adolescents and their families around substance use. Substance Use and The Acute Patient is a unique and valuable contribution to the literature for both consulting psychiatrists, emergency medicine specialists, addiction medicine specialists, and all other medical professionals who provide care for these most complex and underserved patients.
