OBJECTIVE For patients who are actively using a substance and experience psychotic symptoms, determining whether the psychotic symptoms are due to a primary psychotic disorder or are substance induced is challenging, especially in emergency departments, where historical information is limited. This study examined the accuracy and subsequent treatment implications of emergency department diagnoses among substance-using patients who were having their first psychotic episode.

Independent or Substance-Induced Mental Disorders? An Investigation of Comorbidity in an Acute Psychiatric Unit

The majority of current major depressive episode was substance- induced, most often alcohol-induced, and current psychotic disorders were substance-induced in approximately one-third of cases.

A Research Agenda for Assessment and Management of Psychosis in Emergency Department Patients

While psychosis has become a more common presentation in the ED, standardized screening, intervention, and outcome measurement for psychosis has not moved beyond attention to agitation management, so it is imperative that parallel protocols are developed for delivery in theED setting.

Amphetamine Abuse among Patients with First Episode of Acute Psychosis

Clinicians must be trained on how to differentiate between Amphetamine psychosis and other psychoses regarding clinical profile, personality disorders and demographic characteristics because amphetamine psychosis requires a different management.

Diagnostic stability in substance-induced psychosis.

Feasibility of the Psychiatric Research Interview for Substance and Mental Disorders (PRISM) in an acute psychiatric ward

The feasibility of the first Norwegian version of the Psychiatric Research Interview for Substance and Mental Disorders (PRISM) in an acute psychiatric ward was found to be possible, and patients mainly had positive reactions to this extensive interview.

Substance-induced psychosis: a diagnostic conundrum.

There remains a striking paucity of information on the outcome, treatment, and best practice for substance-associated psychotic episodes, so an alternative, broader classification is proposed that better reflects the current evidence base, inferring association rather than causation.

The need for close monitoring of early psychosis and co-occurring substance misuse

Close monitoring of the course and treatment of early-phase psychosis that is accompanied by substance misuse is indicated and could inform the development of more effective dual-diagnosis treatments.



Differences between early-phase primary psychotic disorders with concurrent substance use and substance-induced psychoses.

Differences in demographic, family, and clinical domains confirm substance-induced and primary psychotic disorders as distinct entities and could help emergency clinicians to correctly classify early-phase psychotic disorders that co-occur with substance use.

Prevalence and severity of substance use disorders and onset of psychosis in first-admission psychotic patients

Severity of substance abuse does not appear to be a pivotal correlate of the early features of psychotic illness, and in almost all cases categorized as moderate–severe, the substance diagnosis predated onset of psychosis.

Prevalence of substance misuse in first-episode psychosis

High rates of substance misuse at onset of psychosis are confirmed and there is evidence for an increase in diagnosis of substance-related psychotic disorders over time, particularly among young males.

Substance misuse at presentation to an early psychosis program

This study confirms the high rates of substance misuse, in particular cannabis, in first-episode psychosis, in the general population and implications for treatment are addressed.

A comparison of psychotic and nonpsychotic substance users in the psychiatric emergency room.

Current illicit drug and alcohol users were identified by laboratory evaluation of urine samples from nonpsychotic patients without a primary clinical diagnosis of a substance use disorder seen in a

Assessing substance abuse treatment need: a statewide hospital emergency department study.

EDs can be important venues for detecting persons in need of substance abuse treatment, and excess treatment need was inversely associated with age.

Acute intoxication and substance abuse among patients presenting to a psychiatric emergency service.

Psychiatric Research Interview for Substance and Mental Disorders (PRISM): reliability for substance abusers.

Good to excellent reliability was shown for many diagnoses, including affective disorders, substance use disorders, eating disorders, some anxiety disorders, and psychotic symptoms.

Substance use and the course of early psychosis: a 2-year follow-up of first-admitted subjects

Diagnosing comorbid psychiatric disorders in substance abusers: validity of the Spanish versions of the Psychiatric Research Interview for Substance and Mental Disorders and the Structured Clinical Interview for DSM-IV.

Using the LEAD procedure as a "gold standard," the authors conclude that the Spanish version of the PRISM seems to be a better instrument than the Spanish versions of the SCID for diagnosing major depression and borderline personality disorders in substance abusers.
