Amphetamine Abuse in Emergency Department Patients Undergoing Psychiatric Evaluation
The Journal of Emergency Medicine, 04/30/2012Pomerleau AC et al.
The prevalence of amphetamine–positive urine drug screen (UDS) was high in the study population; however, there was no independent association of amphetamine–positive UDS with involuntary psychiatric hospitalization.
This was a retrospective study of adult patients seen in a single urban university ED who had a psychiatric evaluation and a UDS over a 1–year period.
Eligible patients had results of the UDS, placement of involuntary holds, past psychiatric history, chief complaint, insurance status, and demographic information recorded.
Regression analysis was performed, adjusting for the listed covariates, to evaluate the independent association of amphetamine–positive UDS and involuntary psychiatric hold placement.
A total of 1207 patients were included for analysis.
Amphetamine–positive UDS were found in 14.8% of patients.
Multivariate analysis showed no association of a psychiatric hold due to presence of amphetamines on UDS (adjusted odds ratio [OR] 0.76, 95% confidence interval [CI] 0.55–1.05, p=0.1).
The only significant factor in placement of an involuntary hold was a past psychiatric history (adjusted OR 1.8, 95% CI 1.2–2.7, p=0.005).
