Are day hospitals effective for acutely ill psychiatric patients? A European multicenter randomized controlled trial.

Abstract: Objective: Acute psychiatric day care has been proposed as an alternative to conventional inpatient care, yet the evidence of its effectiveness is inconsistent and based only on single-site studies in 3 countries. The aim of this multicenter randomized controlled trial was to establish the effectiveness of acute day hospital care in a large sample across a range of mental health care systems. Method: The trial was conducted from December 2000 to September 2003 in 5 European countries, with a sample of 1117 voluntarily admitted patients. Immediately before or very shortly after admission to the participating psychiatric facilities, patients were randomly allocated to treatment in a day hospital or an inpatient ward. Psychopathology, treatment satisfaction, subjective quality of life, and social disabilities were assessed at admission, at discharge, and 3 and 12 months after discharge. An intention-to-treat analysis was conducted using fixed-effects linear models with structured error covariance matrices and covariates. Results: Day hospital care was as effective as conventional inpatient care with respect to psychopathologic symptoms, treatment satisfaction, and quality of life. It was more effective on social functioning at discharge and at the 3- and 12-month follow-up assessments. Conclusion: This study, which has more than doubled the existing evidence base, has shown that day hospital care is as effective on clinical outcomes as conventional inpatient care and more effective on social outcomes.

Gender differences in coerced patients with schizophrenia

Abstract: Despite the recent increase of research interest in involuntary treatment and the use of coercive measures, gender differences among coerced schizophrenia patients still remain understudied. It is well recognized that there are gender differences both in biological correlates and clinical presentations in schizophrenia, which is one of the most common diagnoses among patients who are treated against their will. The extent to which these differences may result in a difference in the use of coercive measures for men and women during the acute phase of the disease has not been studied. 291 male and 231 female coerced patients with schizophrenia were included in this study, which utilized data gathered by the EUNOMIA project (European Evaluation of Coercion in Psychiatry and Harmonization of Best Clinical Practice) and was carried out as a multi-centre prospective cohort study at 13 centers in 12 European countries. Sociodemographic and clinical characteristics, social functioning and aggressive behavior in patients who received any form of coercive measure (seclusion and/or forced medication and/or physical restraint) during their hospital stay were assessed. When compared to the non-coerced inpatient population, there was no difference in sociodemographic or clinical characteristics across either gender. However coerced female patients did show a worse social functioning than their coerced male counterparts, a finding which contrasts with the non-coerced inpatient population. Moreover, patterns of aggressive behavior were different between men and women, such that women exhibited aggressive behavior more frequently, but men committed severe aggressive acts more frequently. Staff used forced medication in women more frequently and physical restraint and seclusion more frequently with men. Results of this study point towards a higher threshold of aggressive behavior the treatment of women with coercive measures. This may be because less serious aggressive actions trigger the application of coercive measures in men. Moreover coerced women showed diminished social functioning, and more importantly more severe symptoms from the “excitement/hostile” cluster in contrast to coerced men. National and international recommendation on coercive treatment practices should include appropriate consideration of the evidence of gender differences in clinical presentation and aggressive behaviors found in inpatient populations.

Symptoms associated with victimization in patients with schizophrenia and related disorders.

Abstract: Background: Patients with psychoses have an increased risk of becoming victims of violence. Previous studies have suggested that higher symptom levels are associated with a raised risk of becoming a victim of physical violence. There has been, however, no evidence on the type of symptoms that are linked with an increased risk of recent victimization. Methods: Data was taken from two studies on involuntarily admitted patients, one national study in England and an international one in six other European countries. In the week following admission, trained interviewers asked patients whether they had been victims of physical violence in the year prior to admission, and assessed symptoms on the Brief Psychiatric Rating Scale (BPRS). Only patients with a diagnosis of schizophrenia or related disorders (ICD-10 F20–29) were included in the analysis which was conducted separately for the two samples. Symptom levels assessed on the BPRS subscales were tested as predictors of victimization. Univariable and multivariable logistic regression models were fitted to estimate adjusted odds ratios. Results: Data from 383 patients in the English sample and 543 patients in the European sample was analysed. Rates of victimization were 37.8% and 28.0% respectively. In multivariable models, the BPRS manic subscale was significantly associated with victimization in both samples. Conclusions: Higher levels of manic symptoms indicate a raised risk of being a victim of violence in involuntary patients with schizophrenia and related disorders. This might be explained by higher activity levels, impaired judgement or poorer self-control in patients with manic symptoms. Such symptoms should be specifically considered in risk assessments.

Patient Characteristics Predicting Better Treatment Outcomes in Day Hospitals Compared With Inpatient Wards

Abstract: The study aimed to identify patient characteristics associated with differences in outcomes of acute treatment in day hospitals and conventional hospital wards. Methods: Data were from the European Day Hospital Evaluation (EDEN) (2000–2003), a multicenter randomized controlled trial comparing acute treatment in day hospitals and conventional wards in five European countries. All 880 adult patients in the EDEN study who had a diagnosis of schizophrenia, mood disorders, neurotic disorders, and behavioral syndromes (ICD-10 codes F20–F59) and complete data on baseline variables were included. Outcomes were symptom levels (Brief Psychiatric Rating Scale), subjective quality of life (Manchester Short Assessment of Quality of Life), and social disability (Groningen Social Disabilities Schedule) assessed at discharge and at three and 12 months postdischarge. Mixed- and main-effects models of interaction effects between patient characteristics and outcomes were generated. Results: Patients’ age, diagnostic category, and living status (alone or not) did not predict differences in outcomes between the two settings. However, patients with higher symptom levels at baseline experienced greater symptom improvements after treatment on a ward, and those with more years of education had greater symptom improvements after day hospital treatment. Female patients had more favorable social disability outcomes after day hospital treatment, but no difference between the two settings was found for male patients. Conclusions: More severe symptoms may be a reason for admission to acute treatment on a conventional ward rather than a day hospital. Female patients and those with more education may benefit more from acute treatment in day hospitals. (Psychiatric Services 62:278–284, 2011)

Use of Coercive Measures During Involuntary Hospitalization: Findings From Ten European Countries

Abstract: Objective: Involuntary treatment in mental health care is a sensitive but rarely studied issue. This study was part of the European Evaluation of Coercion in Psychiatry and Harmonization of Best Clinical Practice (EUNOMIA) project. It assessed and compared the use of coercive measures in psychiatric inpatient facilities in ten European countries. Methods: The sample included 2,030 involuntarily admitted patients. Data were obtained on coercive measures (physical restraint, seclusion, and forced medication). Results: In total, 1,462 coercive measures were used with 770 patients (38%). The percentage of patients receiving coercive measures in each country varied between 21% and 59%. The most frequent reason for prescribing coercive measures was patient aggression against others. In eight of the countries, the most frequent measure used was forced medication, and in two of the countries mechanical restraint was the most frequent measure used. Seclusion was rarely administered and was reported in only six countries. A diagnosis of schizophrenia and more severe symptoms were associated with a higher probability of receiving coercive measures. Conclusions: Coercive measures were used in a substantial group of involuntarily admitted patients across Europe. Their use appeared to depend on diagnosis and the severity of illness, but use was also heavily influenced by the individual country. Variation across countries may reflect differences in societal attitudes and clinical traditions. (Psychiatric Services 61: 1012-1017, 2010)

Patients' views and readmissions 1 year after involuntary hospitalisation.

Abstract: Background Little is known about the long-term outcome of involuntary admissions to psychiatric hospitals. Aims To assess involuntary readmissions and patients' retrospective views of the justification of the admission as 1-year outcomes and to identify factors associated with these outcomes. Method Socio-demographic data and readmissions were collected for 1570 involuntarily admitted patients. Within the first week after admission 50% were interviewed, and of these 51% were re-interviewed after 1 year. Results At 1 year, 15% of patients had been readmitted involuntarily, and 40% considered their original admission justified. Lower initial treatment satisfaction, being on benefits, living with others and being of African and/or Caribbean origin were associated with higher involuntary readmission rates. Higher initial treatment satisfaction, poorer initial global functioning and living alone were linked with more positive retrospective views of the admission. Conclusions Patients' views of treatment within the first week are a relevant indicator for the long-term prognosis of involuntarily admitted patients.

Influence of perceived organisational factors on job burnout: survey of community mental health staff

Abstract: Background Staff burnout is a critical issue for mental healthcare delivery, as it can lead to decreased work performance and, ultimately, to poorer treatment outcomes. Aims To explore the relative weight of job-related characteristics and perceived organisational factors in predicting burnout in staff working in community-based psychiatric services. Method A representative sample of 2000 mental health staff working in the Veneto region, Italy, participated. Burnout and perceived organisational factors were assessed by using the Organizational Checkup Survey. Results Overall, high levels of job distress affected nearly two-thirds of the psychiatric staff and one in five staff members suffered from burnout. Psychiatrists and social workers reported the highest levels of burnout, and support workers and psychologists, the lowest. Burnout was mostly predicted by a higher frequency of face-to-face interaction with users, longer tenure in mental healthcare, weak work group cohesion and perceived unfairness. Conclusions Improving the workplace atmosphere within psychiatric services should be one of the most important targets in staff burnout prevention strategies. The potential benefits of such programmes may, in turn, have a favourable impact on patient outcomes.

Psychological interventions for antisocial personality disorder

Abstract: BACKGROUND: Antisocial personality disorder (AsPD) is associated with a wide range of disturbance including persistent rule-breaking, criminality, substance misuse, unemployment, homelessness and relationship difficulties. OBJECTIVES: To evaluate the potential beneficial and adverse effects of pharmacological interventions for people with AsPD. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2009, Issue 3), MEDLINE (1950 to September 2009), EMBASE (1980 to 2009, week 37), CINAHL (1982 to September 2009), PsycINFO (1872 to September 2009) , ASSIA (1987 to September 2009) , BIOSIS (1985 to September 2009), COPAC (September 2009), National Criminal Justice Reference Service Abstracts (1970 to July 2008), Sociological Abstracts (1963 to September 2009), ISI-Proceedings (1981 to September 2009), Science Citation Index (1981 to September 2009), Social Science Citation Index (1981 to September 2009), SIGLE (1980 to April 2006), Dissertation Abstracts (September 2009), ZETOC (September 2009) and the metaRegister of Controlled Trials (September 2009). SELECTION CRITERIA: Controlled trials in which participants with AsPD were randomly allocated to a pharmacological intervention and a placebo control condition. Two trials comparing one drug against another without a placebo control are reported separately. DATA COLLECTION AND ANALYSIS: Three review authors independently selected studies. Two review authors independently extracted data. We calculated mean differences, with odds ratios for dichotomous data. MAIN RESULTS: Eight studies met the inclusion criteria involving 394 participants with AsPD. Data were available from four studies involving 274 participants with AsPD. No study set out to recruit participants solely on the basis of having AsPD, and in only one study was the sample entirely of AsPD participants. Eight different drugs were examined in eight studies. Study quality was relatively poor. Inadequate reporting meant the data available were generally insufficient to allow any independent statistical analysis. The findings are limited to descriptive summaries based on analyses carried out and reported by the trial investigators. All the available data were derived from unreplicated single reports. Only three drugs (nortriptyline, bromocriptine, phenytoin) were effective compared to placebo in terms of improvement in at least one outcome. Nortriptyline was reported in one study as superior for men with alcohol dependency on mean number of drinking days and on alcohol dependence, but not for severity of alcohol misuse or on the patient's or clinician's rating of drinking. In the same study, both nortriptyline and bromocriptine were reported as superior to placebo on anxiety on one scale but not on another. In one study, phenytoin was reported as superior to placebo on the frequency and intensity of aggressive acts in male prisoners with impulsive (but not premeditated) aggression. In the remaining two studies, both amantadine and desipramine were not superior to placebo for adults with opioid and cocaine dependence, and desipramine was not superior to placebo for men with cocaine dependence. AUTHORS' CONCLUSIONS: The body of evidence summarised in this review is insufficient to allow any conclusion to be drawn about the use of pharmacological interventions in the treatment of antisocial personality disorder.

A cross-sectional prospective study of seclusion, restraint and involuntary medication in acute psychiatric wards: patient, staff and ward characteristics

Abstract: Previous research on mental health care has shown considerable differences in use of seclusion, restraint and involuntary medication among different wards and geographical areas This study investigates to what extent use of seclusion, restraint and involuntary medication for involuntary admitted patients in Norwegian acute psychiatric wards is associated with patient, staff and ward characteristics The study includes data from 32 acute psychiatric wards Multilevel logistic regression using Stata was applied with data from 1016 involuntary admitted patients that were linked to data about wards The sample comprised two hierarchical levels (patients and wards) and the dependent variables had two values (0 = no use and 1 = use) Coercive measures were defined as use of seclusion, restraint and involuntary depot medication during hospitalization The total number of involuntary admitted patients was 1214 (35% of total sample) The percentage of patients who were exposed to coercive measures ranged from 0-88% across wards Of the involuntary admitted patients, 424 (35%) had been secluded, 117 (10%) had been restrained and 113 (9%) had received involuntary depot medication at discharge Data from 1016 patients could be linked in the multilevel analysis There was a substantial between-ward variance in the use of coercive measures; however, this was influenced to some extent by compositional differences across wards, especially for the use of restraint The substantial between-ward variance, even when adjusting for patients' individual psychopathology, indicates that ward factors influence the use of seclusion, restraint and involuntary medication and that some wards have the potential for quality improvement Hence, interventions to reduce the use of seclusion, restraint and involuntary medication should take into account organizational and environmental factors
