Substance Use in Patients Admitted to the Psychiatric Emergency Department in Northern Iran

Abstract

Background: Acute psychiatric problems are increasingly observed following substance abuse in emergency departments. To address this significant societal issue, it is essential to understand its various dimensions in order to develop comprehensive control policies. Objectives: This study aimed to evaluate substance use and its related factors in patients admitted to a psychiatric emergency ward in Sari, Mazandaran, Iran. Methods: This cross-sectional study was conducted on all patients admitted to the Emergency Department of Zare Referral Psychiatry hospital during 2011 - 2012. A checklist of demographic and psychiatric factors was completed for each patient based on their medical records. Urine rapid tests were routinely conducted in this department to screen for drug consumption. Descriptive statistics, central and dispersion indices, and the chi-square test were used to analyze the data. Results: A total of 578 cases, comprising 406 males (70.2%) and 172 females (29.8%), were examined. The mean age of patients was 34.7 ± 11.2 years. The most common symptoms reported were aggression (50.5%), insomnia (11.2%), paranoia (10.7%), and self-talk (8.1%), respectively. The most frequent final clinical diagnosis was bipolar disorder in 145 cases (25.1%), followed by schizophrenia in 131 cases (22.7%), and substance-induced psychotic disorder in 63 cases (10.9%). In the substance use screening among patients, the urine test was positive for morphine in 17.6% of the patients. Methamphetamine, methadone, and cannabis tests were positive in 16.1%, 9.5%, and 3.5% of cases, respectively. Among patients with positive urine tests (for methamphetamine, methadone, or morphine), the most common clinical diagnosis was substance-induced psychotic disorder, followed by schizophrenia. Schizophrenia and substance-induced psychotic disorder were the two most common diagnoses in patients with positive cannabis urine tests, respectively. Conclusions: The high rate of substance abuse among psychiatric emergency patients, often co-occurring with other psychiatric disorders, the significant prevalence of psychosis, and the behavioral risks associated with these patients emphasize the need for special attention to this biopsychosocial problem.
