Efficacy of an emergency department-based multicomponent intervention for smokers with substance use disorders

The efficacy of brief emergency department (ED)-based interventions for smokers with concurrent alcohol or substance use is unknown. We performed a subgroup analysis of a trial enrolling adult smokers in an urban ED, focusing on subjects who screened positive for alcohol abuse or illicit drug use. Subjects receiving usual care (UC) were given a smoking cessation brochure; those receiving enhanced care (EC) got the brochure, a brief negotiated interview, 6. weeks of nicotine patches, and a telephone call. Follow-up occurred at 3. months. Of 340 subjects in the parent study, 88 (25.9%) reported a substance use disorder. At 3. months, substance users receiving EC were more likely to be tobacco-abstinent than those receiving UC (14.6% versus 0%, p=.015), and to self-identify as nonsmokers (12.5% v. 0%, p=.03). This finding suggests that concurrent alcohol or substance use should not prevent initiation of tobacco dependence treatment in the ED.
