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. METHODS Emergency… Expand
Differentiating first episode substance induced and primary psychotic disorders with concurrent substance use in young people
TLDR
This clinical profile of SIPD could help to facilitate the accurate diagnosis and treatment of SipD versus PPD in young people with first episode psychosis admitted to an inpatient psychiatric service. Expand
Independent or Substance-Induced Mental Disorders? An Investigation of Comorbidity in an Acute Psychiatric Unit
TLDR
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. Expand
Drug screens for psychiatric patients in the emergency department: evaluation and recommendations.
TLDR
Urine toxicology screens do not add significant diagnostic value to all ED psychiatric evaluations when combined with standard substance use histories, and a positive blood alcohol level was associated independently with a patient's receiving one of these diagnoses while a positive alcohol use history was not. Expand
Substance-induced psychotic disorders: 13-year data from a de-addiction centre and their clinical implications.
TLDR
The present study showed that the presentation of SIPDs is similar to the primary psychotic disorder and this has management implication, and only alcohol and cannabis were implicated as causative agents. Expand
Primary psychosis with comorbid drug abuse and drug-induced psychosis: Diagnostic and clinical evolution at follow up.
TLDR
There was no evidence that Drug Induced psychotic patients' symptoms tend to improve more after cessation of drug abuse, and an earlier age of onset was found in primary psychotic patients, particularly for patients diagnosed as affected by schizophrenia at follow up. Expand
A Research Agenda for Assessment and Management of Psychosis in Emergency Department Patients
TLDR
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. Expand
Amphetamine Abuse among Patients with First Episode of Acute Psychosis
Introduction: Amphetamine abuse may be associated with risk for psychosis and may have a causative role in the development of psychosis. Aim of the Study: To Identifying the prevalence of amphetamineExpand
Clinical characteristics of primary psychotic disorders with concurrent substance abuse and substance-induced psychotic disorders: A systematic review
TLDR
There remains a striking paucity of information on the psychopathology, clinical characteristics and outcome of SIPD, and the need for further research in this area is highlighted. Expand
Substance-Induced Psychosis and Co-occurring Psychotic Disorders
TLDR
Specific behavioral and pharmacologic interventions are necessary for treating agitation and psychosis, occurring either in the setting of SIP or primary psychotic disorders, with or without comorbid substance use. Expand

Differences between early-phase primary psychotic disorders with concurrent substance use and substance-induced psychoses.
TLDR
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. Expand
Prevalence and severity of substance use disorders and onset of psychosis in first-admission psychotic patients.
TLDR
Severity of substance abuse does not appear to be a pivotal correlate of the early features of psychotic illness. Expand
Prevalence of substance misuse in first-episode psychosis.
TLDR
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. Expand
Substance misuse at presentation to an early psychosis program
TLDR
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. Expand

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 aExpand
Assessing substance abuse treatment need: a statewide hospital emergency department study.
TLDR
EDs can be important venues for detecting persons in need of substance abuse treatment, and excess treatment need was inversely associated with age. Expand
Acute intoxication and substance abuse among patients presenting to a psychiatric emergency service.
TLDR
The findings suggest that an important role for the PES is a "filter" to triage patients to the appropriate treatment setting and that this role is fulfilled when the Pes is able to provide sufficient time and resources for evaluation and/or stabilization. Expand
Psychiatric Research Interview for Substance and Mental Disorders (PRISM): reliability for substance abusers.
TLDR
Good to excellent reliability was shown for many diagnoses, including affective disorders, substance use disorders, eating disorders, some anxiety disorders, and psychotic symptoms. Expand
Diagnosis of comorbid psychiatric disorders in substance users assessed with the Psychiatric Research Interview for Substance and Mental Disorders for DSM-IV.
TLDR
Most DSM-IV psychiatric disorders can be assessed in substance-abusing subjects with acceptable to excellent reliability by using specifically designed procedures. Expand
Substance use and the course of early psychosis: a 2-year follow-up of first-admitted subjects
TLDR
Persistent substance misuse after a first admission for psychosis has a deleterious impact on clinical outcome, and early identification and treatment of substance use is essential in the care of subjects with incipient psychosis. Expand
