Factors associated with 30-day drug-related emergency department re-attendance among methamphetamine users: a territory-wide retrospective study in Hong Kong

Drug-related ED re-attendance is common among methamphetamine users. Failed previous detoxification treatment and drug-induced psychosis are factors significantly associated with such re-attendances. The limited impact of the severity of acute toxicity and psychosocial interventions underscores the importance of primary prevention of methamphetamine misuse through public education and drug-control policy, and early multidisciplinary interventions before progression to drug-induced psychosis.
