HRI Hospital’s inpatient dual diagnosis program is for adults with co-occurring psychiatric and substance abuse disorders. This unit can treat patients whose primary disorder is substance use. The program aims to stabilize both conditions, identify the root cause of the problems and provide around-the-clock intensive care. Our goal is to help these patients move toward long-term mental wellness and sobriety. Before addressing the co-occurring disorders, it’s important to know which came first. For example, was the patient’s anxiety disorder caused by drug use or does he or she use drugs to alleviate an underlying mental disorder? The answer to this question is crucial to recovery.
