Substance abuse and recovery in a Psychiatric Intensive Care Unit

The rate and impact of substance misuse in psychiatric intensive care units (PICUs) in the UK

Purpose

This paper aims to understand the current scale of substance misuse in psychiatric intensive care units (PICUs), identify how substance misuse affects members of staff, patients and the running of wards and explore with staff what resources would be most useful to more effectively manage substance misuse and dual diagnosis on PICUs.

Design/methodology/approach

The paper used a mixed-methods approach, using a quantitative survey to determine the extent of substance use in PICUs and a co-design workshop to understand the impact of substance misuse on PICU wards, staff and patients.

Findings

The estimated rate of substance misuse in PICUs over a 12-month period is 67%, with cannabis the most frequently used substance. Despite the range of problems experienced on PICUs because of substance misuse, the availability of training and resources for staff was mixed.

Research limitations/implications

The findings may not be fully generalisable as research participants were members of a national quality improvement programme, and therefore, may not be representative of all PICUs. Data was collected from clinicians only; if patients were included, they might have provided another perspective on substance misuse on PICUs.

Practical implications

This paper emphasises the importance of substance misuse training for PICU staff to adequately respond to patients who misuse substances, improve the ward environment, staff well-being and patient outcomes.

Originality/value

This paper provides an updated estimation of rates of substance misuse in PICUs over a 12-month period and make suggestions for a training programme that can better support staff to address substance misuse on PICUs.

Gender differences in 353 inpatients with acute psychosis: The experience of one Psychiatric Emergency Service of Turin

The aim of the study is to evaluate gender-related socio-demographic and clinical differences in a large sample of inpatients with schizophrenia spectrum disorder. A sample of 353 acute patients, consecutively hospitalized between January 2007 and December 2008 in the Psychiatric Emergency Service of the San Giovanni Battista Hospital, was recruited. Psychiatric assessment included the Clinical Global Impression Scale-Severity (CGI-S), the Brief Psychiatric Rating Scale (BPRS) and the Global Assessment of Functioning (GAF). Differences between the groups were tested using chi-square test and ANOVA. Data were analyzed using a three-way MANOVA with the six BPRS scales with repeated measures for admission/discharge and BPRS total score baseline and independent groups for men and women. A two-way ANOVA for repeated measures was performed for CGI-S and GAF. Men were younger, more likely to be never married, more often substance abusers. Male patients showed both lower anxious-depressive and anergia symptom scores and higher activation symptom scores than female patients. Brief hospitalization was shown to be highly effective in both groups. Females showed a significantly better improvement in anergia and activation than males. The present evidence suggests that management of acute psychosis should target specific gender differences which should influence therapeutic approach in all its modalities.

Religious convictions in patients with epilepsy-associated affective disorders: a controlled study from a psychiatric acute department

Patients with epilepsy often have different mood symptoms and behavioral trait characteristics compared to the non-epileptic population. In the present prospective study, we aimed to assess differences in behavioral trait characteristics between acutely admitted, psychiatric in-patients with epilepsy-associated depressive symptoms and gender/age-matched patients with major depression. Patients with epilepsy-associated depression had significantly higher scores for "religious convictions," "philosophical and intellectual interests" and "sense of personal destiny." These behavioral trait characteristics at admission or in clinical history should alert the psychiatrist and lead to closer examination for a possible convulsive disorder.

[Seclusion in emergency psychiatry]

BACKGROUND

In Norway, seclusion (also called «shielding» or «open-area seclusion») is often used as an intervention in inpatient psychiatric wards as a continuation of milieu therapy, but the method remains controversial in health policy. A psychiatrist or occasionally a psychologist is responsible for making a decision on seclusion pursuant to Section 4-3 of the Mental Health Care Act. Because of the uncertainty regarding the content and academic legitimacy of this model, we have undertaken a review of available literature on the justification, practical application and effect of the Norwegian tradition of seclusion.

MATERIAL AND METHOD

The article is based on systematic searches in national and international databases for the years 1930-2013.

RESULTS

The seclusion method is closely associated with the development of psychiatric institutions, especially the establishment of emergency units and milieu therapy. The concept of seclusion covers a variety of approaches, and its knowledge base is generally poor. Clinical treatment studies are largely of older origin and most likely not descriptive of current practices. The absence of efficacy studies means that as of today, we have little knowledge on the benefits of using seclusion as treatment.

INTERPRETATION

We detected a major discrepancy between the clinical ubiquity of the seclusion method and its knowledge basis. There is a clear need for more research on various types of seclusion to be able to assess the effects of seclusion in current practice.

Substance use disorders in hospitalized psychiatric patients: the experience of one psychiatric emergency service in Turin

In the present study we sought: 1) to estimate the frequency of substance use disorders (SUD), and 2) to investigate whether there is a mere association between diagnosis and SUD in a large cohort of patients with severe psychiatric disorders representative of the usual setting and modality of care of a psychiatric emergency service in a geographically well-defined catchment area in Italy, independent of sociodemographic features, anamnestic data and clinical status. The study was conducted between January 2007 and December 2008. The following rating scales were performed: the Clinical Global Impression-Severity (CGI-S), the Global Assessment of Functioning scale (GAF) and the Brief Psychiatric Rating Scale (BPRS). Factors found to be associated (p<0.05) with SUD[+] in the univariate analyses were subjected to multilevel logistic regression model with a backward stepwise procedure. Among 848 inpatients of our sample 29.1% had a SUD codiagnosis. Eleven factors accounted for 30.6% of the variability in SUD[+]: [a] a Personality Disorder diagnosis, [b] a Depressive Disorder diagnosis, [c] male gender, [d] previous outpatient contacts, [e] single marital status, [f] no previous psychiatric treatments, [g] younger age, [h] lower scores for BPRS Anxiety-depression and [i] BPRS Thought Disturbance, [l] higher scores for BPRS Activation and [m] BPRS Hostile-suspiciousness. The findings are important in identifying (1) the complexity of the clinical presentation of SUD in a inpatients sample, (2) the need for collaboration among health care workers, and (3) the need to develop and apply treatment programs that are targeted at particular risk groups.

The effects of motivational interviewing on patients with comorbid substance use admitted to a psychiatric emergency unit - a randomised controlled trial with two year follow-up

BACKGROUND

The prevalence of substance use in people acutely admitted to in-patient psychiatric wards is high and the patients` duration of stay is limited. Motivational interviewing is a method with evidence based effect in short interventions. The aims of the present study were to compare the effects of 2 sessions of motivational interviewing and treatment as usual (intervention group) with treatment as usual only (control group) on adult patients with comorbid substance use admitted to a psychiatric in-patient emergency unit.

METHODS

This was an open randomised controlled trial including 135 patients where substance use influenced the admittance. After admission and assessments, the patients were allocated to the intervention group (n = 67) or the control group (n = 68). The primary outcome was self-reported days per month of substance use during the last 3 months at 3, 6, 12 and 24 months after inclusion. Data was analysed with a multilevel linear repeated measures regression model.

RESULTS

Both groups reduced substance use during the first 12 months with no substantial difference between the 2 groups. At 2 year follow-up, the control group had increased their substance use with 2.4 days (95% confidence interval (CI) -1.5 to 6.3), whereas the intervention group had reduced their monthly substance use with 4.9 days (95% CI 1.2 to 8.6) compared to baseline. The 2 year net difference was 7.3 days of substance use per month (95% CI 1.9 to 12.6, p < 0.01) in favour of the intervention group.

CONCLUSIONS

The present study suggests that 2 sessions of motivational interviewing to patients with comorbid substance use admitted to a psychiatric emergency unit reduce substance use frequency substantially at 2 year follow-up.

Involuntary hospitalization of first-episode psychosis with substance abuse during a 2-year follow-up

OBJECTIVE

To investigate whether substance abuse (alcohol or illegal drugs) in patients with first-episode psychosis (FEP) influenced treatment outcomes such as involuntary hospitalization during follow-up.

METHOD

First-episode psychosis patients (n = 103) with consecutive admissions to a comprehensive early psychosis program were included and followed for 2 years. Assessment measures were the Positive and Negative Syndrome Scale, Global Assessment of Functioning, and the Clinician Rating Scale (for substance abuse).

RESULTS

Twenty-four per cent of patients abused either alcohol or drugs at baseline. The dropout rate at 2 years was the same for substance abusers as for non-abusers. Substance use was not reduced over the 2-year period. At 2-year follow-up, 72% of substance abusers and 31% of non-abusers had experienced at least one occasion of involuntary hospitalization. Patients with substance abuse had significantly higher risk for involuntary hospitalization during follow-up (OR 5.2).

CONCLUSION

To adequately treat patients with FEP, clinicians must emphasize treatment of the substance abuse disorder, as well as the psychotic illness. Patients with defined comorbid substance use disorders and FEP are likely to have poorer treatment response than those with psychosis alone.

Short-term prediction of threatening and violent behaviour in an Acute Psychiatric Intensive Care Unit based on patient and environment characteristics

BACKGROUND

The aims of the present study were to investigate clinically relevant patient and environment-related predictive factors for threats and violent incidents the first three days in a PICU population based on evaluations done at admittance.

METHODS

In 2000 and 2001 all 118 consecutive patients were assessed at admittance to a Psychiatric Intensive Care Unit (PICU). Patient-related conditions as actuarial data from present admission, global clinical evaluations by physician at admittance and clinical nurses first day, a single rating with an observer rated scale scoring behaviours that predict short-term violence in psychiatric inpatients (The Brøset Violence Checklist (BVC)) at admittance, and environment-related conditions as use of segregation or not were related to the outcome measure Staff Observation Aggression Scale-Revised (SOAS-R). A multiple logistic regression analysis with SOAS-R as outcome variable was performed.

RESULTS

The global clinical evaluations and the BVC were effective and more suitable than actuarial data in predicting short-term aggression. The use of segregation reduced the number of SOAS-R incidents.

CONCLUSIONS

In a naturalistic group of patients in a PICU segregation of patients lowers the number of aggressive and threatening incidents. Prediction should be based on clinical global judgment, and instruments designed to predict short-term aggression in psychiatric inpatients.

Effects of legal and illegal use of benzodiazepines at acute admission to a psychiatric acute department

BACKGROUND

In the psychiatric acute and emergency services patients present in severe crisis often complicated by behavioral problems, substance use, and multiple axis 1 diagnoses. In these clinical settings both legal and illegal use of benzodiazepines are difficult to evaluate since benzodiazepines could in some patients be regarded as first line treatment and in other patients as the cause of the acute psychiatric condition. The aims of this study were to evaluate the frequency and clinical effects of both legal and illegal use of benzodiazepines at admittance to a psychiatric acute department.

METHODS

All patients acutely admitted to a Norwegian acute psychiatric university department serving a catchment area were asked about use of benzodiazepines, other medications and substances before admission. Patients were asked to give urine samples for analyses of benzodiazepines and substances.

RESULTS

In 227 consecutive admissions there was legal use of benzodiazepines before admission in 39%, illegal use in 13% and no use in 48%. Patients with legal use of benzodiazepines were older, used more often antidepressants and a higher number of prescribed psychotropic medications. Illegal users of benzodiazepines more often used other illegal substances, were evaluated as clinically affected by a substance at admittance and were diagnosed with a substance use disorder. Patients with psychoses or major affective disorders treated with adequate medication (antidepressants, antipsychotics or mood-stabilizers) before admission more often received benzodiazepines than patients without adequate medication.

CONCLUSIONS

The patients using benzodiazepines at admittance to psychiatric acute departments could be divided in illegal and legal users. The illegal users were young, used illegal substances and were more often regarded clinically affected by substances at admittance. The legal users were older, did not use other substances and were not regarded as clinically affected by substances at admittance. Benzodiazepines were used as adjuvant therapy to specific pharmacological treatment with antidepressants, antipsychotics or mood stabilizers for major psychiatric disorders.

Acute Unstable Depressive Syndrome (AUDS) is associated more frequently with epilepsy than major depression

Background

Depressive disorders are frequent in epilepsy and associated with reduced seizure control. Almost 50% of interictal depressive disorders have to be classified as atypical depressions according to DSM-4 criteria. Research has mainly focused on depressive symptoms in defined populations with epilepsy (e.g., patients admitted to tertiary epilepsy centers). We have chosen the opposite approach. We hypothesized that it is possible to define by clinical means a subgroup of psychiatric patients with higher than expected prevalence of epilepsy and seizures. We hypothesized further that these patients present with an Acute Unstable Depressive Syndrome (AUDS) that does not meet DSM-IV criteria of a Major Depressive Episode (MDE). In a previous publication we have documented that AUDS patients indeed have more often a history of epileptic seizures and abnormal EEG recordings than MDE patients (Vaaler et al. 2009). This study aimed to further classify the differences of depressive symptoms at admittance and follow-up of patients with AUDS and MDE.

Methods

16 AUDS patients and 16 age- and sex-matched MDE patients were assessed using the Symptomatic Organic Mental Disorder Assessment Scale (SOMAS), the Montgomery and Åsberg Depression Rating Scale (MADRS), and the Mini-Mental State Test (MMST), at day 2, day 4-6, day 14-16 and 3 months after admittance to a psychiatric emergency unit. Life events were assessed with The Social Readjustment Rating Scale (SRRS) and The Life Experience Survey (LES). We also screened for medication serum levels and illicit drug metabolites in urine.

Results

AUDS patients had significantly higher SOMAS scores (average score at admission 6.6 ± 0.8), reflecting increased symptom fluctuation and motor agitation, and decreased insight and concern compared to MDE patients (2.9 ± 0.7; p < 0.001). Degree of mood depression, cognition, life events, drug abuse and medication did not differ between the two groups.

Conclusions

AUDS patients present with rapidly fluctuating mood symptoms, motor agitation and relative lack of insight and concern. Seizures, epilepsy and EEG abnormalities are overrepresented in AUDS patients compared to MDE patients. We suggest that the study of AUDS patients may offer a new approach to better understanding epilepsy and its association with depressive disorders.

Symptoms of epilepsy and organic brain dysfunctions in patients with acute, brief depression combined with other fluctuating psychiatric symptoms: a controlled study from an acute psychiatric department

BACKGROUND

In psychiatric acute departments some patients present with brief depressive periods accompanied with fluctuating arrays of other psychiatric symptoms like psychosis, panic or mania. For the purpose of the present study we call this condition Acute Unstable Depressive Syndrome (AUDS). The aims of the present study were to compare clinical signs of organic brain dysfunctions and epilepsy in patients with AUDS and Major Depressive Episode (MDE).

METHODS

Out of 1038 consecutive patients admitted to a psychiatric acute ward, 16 patients with AUDS and 16 age- and gender-matched MDE patients were included in the study. Using standardized instruments and methods we recorded clinical data, EEG and MRI.

RESULTS

A history of epileptic seizures and pathologic EEG activity was more common in the AUDS group than in the MDE group (seizures, n = 6 vs. 0, p = 0.018; pathologic EEG activity, n = 8 vs. 1, p = 0.015). Five patients in the AUDS group were diagnosed as having epilepsy, whereas none of those with MDE had epilepsy (p = 0.043). There were no differences between the groups regarding pathological findings in neurological bedside examination and cerebral MRI investigation.

CONCLUSION

Compared to patients admitted with mood symptoms fulfilling DSM 4 criteria of a major depressive disorder, short-lasting atypical depressive symptoms seem to be associated with a high frequency of epileptic and pathologic EEG activity in patients admitted to psychiatric acute departments.

Evaluation of a urine on-site drugs of abuse screening test in patients admitted to a psychiatric emergency unit

The objective of this study was to characterize the usefulness and reliability of a commonly used urinary on-site drugs of abuse screening test device when used routinely at admittances to a psychiatric emergency unit. Urine samples from 262 emergency psychiatric admittances representing 217 patients were analyzed by a commercially available on-site test for the detection of amphetamines, benzodiazepines, cannabis, cocaine, and opiates in urine. The samples were first screened by nurses at the psychiatric department, thereafter by 2 technicians at the laboratory, and finally, analyzed by liquid chromatography/mass spectrometry. Results of 45.8% of the screening tests were true negative for all 5 drugs/drug groups tested, whereas those of 29.4% were true positive for 1 or several drugs/drug groups and true negative for the others. Thus, in total, 75.2% were correct for all 5 drugs/drug groups. In general, the sensitivities (42.9%-90.0% for the various drug groups) were lower than the specificities (92.7%-100.0%). The accuracies were 86.3% for benzodiazepines, 92.4% for cannabis, 94.7% for opiates, and 97.0% for amphetamines. No cocaine was found in any of the samples. For cannabis, the accuracy was higher among the laboratory technicians than among the nurses. The results from on-site screening testing should not be considered as the final conclusion on the intake of drugs of abuse but must be interpreted with caution.

Substance use at admission to an acute psychiatric department

Substance use is prevalent in patients with psychiatric disorders and may cause severe symptoms in addition to complicating the diagnosis of psychiatric disorders. The aims of the study were to find the prevalence in use of alcohol, drugs, benzodiazepines, hypnotics, opiates and stimulants, and to find the prevalence of substance use disorders at admission to an acute psychiatric department receiving all admissions from a catchment area. Patients were interviewed about use of medications and intoxicating substances during the last week before admission in 227 consecutive admissions. Urine samples were analysed with the liquid chromatography with mass spectrometry (LC-MS) method. Use of substances was determined from reported use and findings in urine samples. Diagnoses were set at discharge according to ICD-10 research criteria. In 81.9% of the admissions, the patient had used alcohol, drugs, benzodiazepines, hypnotics, opiates or stimulants prior to admission. More men used alcohol, cannabis and stimulants, whereas more women used benzodiazepines. In 31.7% of the admissions, 49.5% of men and 16.4% of women, the patients had a substance use disorder (ICD-10, F10-19). Patients with substance use disorders had a shorter stay in hospital than other patients, and patients with no psychiatric disorder other than substance use disorders had a median length of stay of 2 days. Most patients had used psychoactive substances before admission to the acute psychiatric department, and half of the men had a substance use disorder.
