Clinical and demographic differences between voluntary and involuntary psychiatric admissions in a university hospital in Brazil

Predictors for early and long-term readmission in involuntarily admitted patients

BACKGROUND

It is a common aim to reduce psychiatric readmissions. Although risk factors for readmissions were described, specific data in the group of patients with potentially aversively experienced involuntary admissions are lacking. To better understand underlying mechanisms, it is important to identify factors that are linked to readmissions in this specific patient group, which is the purpose of the current paper.

METHODS

A four-year cohort of N = 3575 involuntary admissions (IA) was followed-up for subsequent re-hospitalization. Demographic, administrative and clinical factors associated with short- (within 30 days) or long-term (> 30 days) readmissions were examined using logistic regression modelling.

RESULTS

Almost half of all IA cases were readmitted within the observation period, whereof every fifth readmission was within the first month after discharge from the involuntary index hospitalization. Adjusted regression modelling revealed problematic substance use at admission and assisted living or homelessness as risk factors for readmission, while high functioning at discharge, anxiety disorders, no subsequent treatment after discharge or IA due to danger to others were negatively associated with readmission. Factors specifically linked to short-term readmission were substance use and personality disorders, abscondence or discharge by initiation of the clinic, as well as being discharged to any place except the patient's home. There were no specific risk-factors for long-term readmission.

CONCLUSIONS

To prevent readmissions after IA, especially for patients at risk, the aim of treatment strategies should be to focus on intensive discharge planning, enable continuous treatment in the outpatient setting, and provide social support.

Prevalence and correlates of restrictive interventions in an Irish child and adolescent psychiatric unit: a 4-year retrospective study

BACKGROUND

There has been a global effort to reduce the use of restrictive interventions (RIs) in healthcare settings. In order to reduce unnecessary RIs, it is essential to understand their use in mental health settings. To date, there have been few studies examining the use of RIs in child and adolescent mental health settings, with no such studies in Ireland.

AIMS

The purpose of this study is to examine the prevalence and frequency of physical restraints and seclusion and to identify any associated demographic and clinical characteristics.

METHODS

This is a 4-year retrospective study of the use of seclusion and physical restraint in an Irish child and adolescent psychiatric inpatient unit from 2018 to 2021. Computer-based data collection sheets and patient records were retrospectively reviewed. Eating disorder and non-eating disorder samples were analysed.

RESULTS

Of 499 hospital admissions from 2018 to 2021, 6% (n = 29) had at least one episode of seclusion and 18% (n = 88) had at least one episode of physical restraint. Age, gender and ethnicity were not significantly associated with rates of RI. Unemployment, prior hospitalization, involuntary legal status and longer length of stay were significantly associated with higher rates of RIs in the non-eating disorder group. Involuntary legal status was associated with higher rates of physical restraint in the eating disorder group. Patients with a diagnosis of eating disorder and psychosis had the highest prevalence of physical restraints and seclusions respectively.

CONCLUSIONS

Identifying youth who are at greater risk of requiring RIs may allow early and targeted intervention and prevention.

Risk factors for involuntary admission in a Romanian patient sample

BACKGROUND

Involuntary admission is widely used in psychiatry, usually requiring that the patient present an imminent danger to himself or others. Previous studies have established several predictors for involuntary admission, but they have been almost exclusively conducted in Western European or North American countries. By contrast, data on this topic from Eastern European countries is virtually absent. Historically, involuntary admission has been often used as a tool for political repression in Romania before the fall of the communist regime. While there have been significant changes in the legal framework in the last 30 years, there is still no real-world data to build upon.

METHODS

We analyzed a sample of 177 patients admitted to the "Alexandru Obregia" psychiatric hospital in Bucharest between November 2022 and January 2023, of which 49.7% (88) were involuntary hospitalizations. We collected socio-demographic and clinical data by both by direct interview, and by consulting patient records, attending physicians and relatives.

RESULTS

Socio-demographic factors predictive for involuntary admission were unemployment, lower income, and urban living. Of the clinical variables analyzed, diagnosis of psychosis or mania on admission carried increased risk of involuntary hospitalization, as did nonadherence to treatment, higher disease severity and aggression. Hospital presentation by police or ambulance carried significant additional risk compared to self-referral.

CONCLUSION

Certain categories of patients are considerably more likely to be involuntarily hospitalized and there appears to be considerable interrelatedness between the identified risk factors.

Who is coercively admitted to psychiatric wards? Epidemiological analysis of inpatient records of involuntary psychiatric admissions to a University General Hospital in Greece for the years 2008-2017

BACKGROUND

Involuntary psychiatric admissions are a widely used practice despite ethical concerns about coercion. There are particular concerns that vulnerable groups, such as single, unemployed or racial minorities, may be more subjected to such practices.

AIM

We aimed to investigate the social patterns of involuntary psychiatric admissions from 2008 to 2017 at University General Hospital in Ioannina, Greece.

METHOD

We retrospectively assessed inpatient records from 2008 to 2017 of patients admitted to the Department of Psychiatry of the Ioannina University General Hospital, Northwestern Greece. Alternative patients of alternative years were selected for inclusion; this yielded 332 patients involuntarily admitted, corresponding to 28.5% of total involuntary psychiatric admissions.

RESULTS

Over the 10-year period, the overall numbers of annual involuntary psychiatric admissions remained relatively stable, as did the length of hospital stay (mean = 23.8 days). The most common disorder upon admission was schizophrenia spectrum disorders, accounting for approximately two-thirds of all admissions, followed by mood disorders (about 20%). There was evidence that people who lacked social support or experienced financial hardship were more greatly represented among those admitted: 70.2% of admitted patients were single and 64.8% were unemployed. Most patients had been admitted to the psychiatric ward in the past (64.2%).

CONCLUSION

Our study indicates potentially worrisome evidence that patients who are in vulnerable positions are at elevated likelihood of being involuntarily admitted to psychiatric wards. Future research is needed to evaluate the socio-demographic patterning of involuntary admissions in other European countries.

Compulsory psychiatric admissions in the canton of Basel-Stadt between September 2013 and April 2022: Analysis of the cantonal database of the Health Department of Basel-Stadt

BACKGROUND

According to federal and cantonal law, persons with an acute mental illness can be admitted to a psychiatric hospital or another suitable institution against their will, when other therapeutic options are not available or have been exhausted. In the canton of Basel-Stadt, this is the responsibility of public health officers employed by the division of Social Medicine of the cantonal Health Department.

AIMS

This study aims to elucidate which factors influence the decision-making of public health officers regarding compulsory admissions over the period from September 2013 to April 2022 in the canton of Basel-Stadt.

METHOD

Leveraging comprehensive clinical data from the health department of the canton Basel-Stadt (N = 5,'550), we estimated a mixed effects logistic regression model to identify factors contributing to the decision of public-health officers to compulsorily admit patients, while controlling for potential clustering effects among public health officers.

RESULTS

The risk for compulsory admissions was most strongly predicted by the presence of potential self-harm. In comparison, while being a strong predictor, potential harm to others played a considerably lesser role. Furthermore, psychiatric syndrome, previous compulsory admissions, and the specific context of evaluation were significant predictors. Finally, we found no meaningful personal bias among public health officers.

CONCLUSION

The results suggest that public health officers' decision-making regarding compulsory admissions focuses on preventing self-harm and, to a lesser degree, harm to others. This indicates that such measures are only used as a measure of last resort, which is in line with current evidence regarding the detrimental effects of compulsory measures on treatment outcomes in psychiatry. Our findings suggest that all relevant stakeholders, including the police, share this perspective. Decision-making regarding compulsory admissions was mostly free of personal biases, suggesting adherence to shared professional standards by public health officers.

Dignity, coercion and involuntary psychiatric care: a study of involuntary and voluntary psychiatry inpatients in Dublin

OBJECTIVES

There is a paucity of research about psychiatric inpatients' experience of dignity. Most of the limited literature on this topic is qualitative. Our study provides quantitative data about self-rated dignity among involuntary and voluntary psychiatry inpatients. We explore relationships between perceived dignity and legal status, coercion, level of insight, diagnosis, and therapeutic alliance, among other parameters.

METHODS

We recruited 107 participants aged 18 years or over from two inpatient psychiatric units in Dublin, Ireland over a 30-month period. Interviews consisted of structured, validated assessment tools. Demographic and clinical data were obtained from patient charts.

RESULTS

Patient Dignity Inventory (PDI) score was non-normally distributed (skewed to the right), with a median score of 63.0 out of 125 (inter-quartile range: 40.0-80.0). On multi-variable testing, lower self-rated dignity was associated with higher perceived coercion, better insight and more negative symptoms. There was no association between dignity and gender, employment status, marital status, ethnicity, age, admission status, diagnosis, working alliance, positive symptoms or cognition.

CONCLUSIONS

Lack of dignity is linked with perceived coercion and negative symptoms, and is seen in patients with better insight. These links merit further study if we are to understand patient dignity in a more nuanced and useful way.KEYPOINTSWe interviewed psychiatric inpatients using the Patient Dignity Inventory and other structured assessment tools.There was no significant difference between voluntary and involuntary patient groups' self-rated dignity.Less self-rated dignity was seen in patients with higher levels of perceived coercion.Patients with better insight reported lower dignity.Dignity scores were not significantly associated with age, gender, ethnicity, diagnosis or length of stay in hospital.

Determinants of compulsory hospitalisation at admission and in the course of inpatient treatment in people with mental disorders-a retrospective analysis of health records of the four psychiatric hospitals of the city of Cologne

BACKGROUND

We aimed to identify differences in predictors of involuntary psychiatric hospitalisation depending on whether the inpatient stay was involuntary right from the beginning since admission or changed from voluntary to involuntary in the course of in-patient treatment.

METHODS

We conducted an analysis of 1,773 mental health records of all cases treated under the Mental Health Act in the city of Cologne in the year 2011. 79.4% cases were admitted involuntarily and 20.6% were initially admitted on their own will and were detained later during the course of in-patient stay. We compared the clinical, sociodemographic, socioeconomic and environmental socioeconomic data (ESED) of the two groups. Finally, we employed two different machine learning decision-tree algorithms, Chi-squared Automatic Interaction Detection (CHAID) and Random Forest.

RESULTS

Most of the investigated variables did not differ and those with significant differences showed consistently low effect sizes. In the CHAID analysis, the first node split was determined by the hospital the patient was treated at. The diagnosis of a psychotic disorder, an affective disorder, age, and previous outpatient treatment as well as the purchasing power per 100 inhabitants in the living area of the patients also played a role in the model. In the Random Forest, age and the treating hospital had the highest impact on the accuracy and decrease in Gini of the model. However, both models achieved a poor balanced accuracy. Overall, the decision-tree analyses did not yield a solid, causally interpretable prediction model.

CONCLUSION

Cases with detention at admission and cases with detention in the course of in-patient treatment were largely similar in respect to the investigated variables. Our findings give no indication for possible differential preventive measures against coercion for the two subgroups. There is no need or rationale to differentiate the two subgroups in future studies.

Real world evidence in involuntary psychiatric hospitalizations: 64,685 cases

OBJECTIVE

We explored hospitalization patterns and the clinical and individual characteristics of a large cohort of patients who underwent involuntary psychiatric hospitalization in Brazil (n=64,685).

METHODS

Data were collected from the District Attorney's Office of the State of São Paulo (Ministério Público do Estado de São Paulo) on all involuntary psychiatric hospitalizations in the city of São Paulo between January 2003 and February 2020. The annual involuntary psychiatric hospitalization rate was calculated and descriptive statistics of the characteristics were produced.

RESULTS

Involuntary psychiatric hospitalizations increased from 5.8 to 25.5 per 100,000 population, with an eight-folder increase in the first 10-year period (2003-2013). The majority of admissions were to public institutions (86.6%), involved a psychotic disorder in the primary diagnosis (26.1%), involved more than one diagnosis (83.7%), and lasted less than 7 days (52.4%). The majority of the patients were aged 18 to 39 years and were single, and readmission was relatively common (13%). Although the reason for admission was missing in many reports (44%), the risk of harm to self or others was the most common (68.5%).

CONCLUSION

This is one of the largest cohorts of involuntary psychiatric hospitalization records ever explored. These findings build upon existing international evidence about involuntary psychiatric hospitalizations and show recent trends in admission rates in the largest city in Brazil.

Factors associated with involuntary psychiatric hospitalization in Portugal

Background

Identifying which factors contribute to involuntary psychiatric hospitalization may support initiatives to reduce its frequency. This study examines the sociodemographic, clinical, and contextual factors associated with involuntary hospitalization of patients from five Portuguese psychiatric departments in 2002, 2007 and 2012.

Methods

Data from all admissions were extracted from clinical files. A Poisson generalized linear model estimated the association between the number of involuntary hospitalizations per patient in one year and sociodemographic, clinical, and contextual factors.

Results

An increment of involuntary hospitalizations was associated with male gender [exp(\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\widehat{\upbeta }$$\end{document}β^) = 1.31; 95%CI 1.06–1.62, p < 0.05], having secondary and higher education [exp(\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\widehat{\upbeta }$$\end{document}β^) = 1.45; 95%CI 1.05–2.01, p < 0.05, and exp(\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\widehat{\upbeta }$$\end{document}β^) = 1.89; 95%CI 1.38–2.60, p < 0.001, respectively], a psychiatric diagnosis of psychosis [exp(\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\widehat{\upbeta }$$\end{document}β^) = 2.02; 95%CI 1.59–2.59, p < 0.001], and being admitted in 2007 and in 2012 [exp(\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\widehat{\upbeta }$$\end{document}β^) = 1.61; 95%CI 1.21–2.16, p < 0.01, and exp(\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\widehat{\upbeta }$$\end{document}β^) = 1.73; 95%CI 1.31–2.32, p < 0.001, respectively].

Conclusions

The findings suggest that involuntary psychiatric hospitalizations in Portugal are associated with several sociodemographic, clinical, and contextual factors. This information may help identify high-risk patients and inform the development of better-targeted preventive interventions to reduce these hospitalizations.

The association between perceived coercion on admission and formal coercive practices in an inpatient psychiatric setting

Involuntary care is a feature of mental health services around the world. In addition to involuntary admission and treatment, specific coercive practices include seclusion and physical restraint. Our study aimed to determine the relationships, if any, between these practices and perceived coercion on admission among psychiatry inpatients in Ireland, as well as any relationships between perceived coercion on admission and variables such as age, gender and diagnosis. We included 107 psychiatry inpatients aged 18 years or over who were admitted to the acute psychiatry admission units in Tallaght University Hospital and Connolly Hospital, Dublin, Ireland over a 30-month period between September 2017 and February 2020. Over a quarter (27.1%) of participating patients had involuntary status; nine (8.4%) had experienced at least one episode of seclusion, and ten (9.3%) had experienced at least one episode of restraint. Perceived coercion on admission was significantly associated with involuntary status and female gender; perceived negative pressures on admission were significantly associated with involuntary status and positive symptoms of schizophrenia; perceived procedural injustice on admission was significantly associated with fewer negative symptoms, involuntary status, cognitive impairment and female gender; and negative affective reactions to hospitalisation on admission were significantly associated with birth in Ireland and being employed. Total score across these four subscales was significantly associated with involuntary status and positive symptoms, and had borderline significant associations with birth in Ireland, being employed and female gender. Overall, perceived coercion on admission, assessed in retrospect by the patient, is more closely associated with involuntary status and symptoms than it is with subsequent formal coercive practices, such as seclusion and restraint. The role of gender merits particular attention in future research, especially in relation to procedural injustice on admission and perceived coercion on admission.

Socio-Demographic and Clinical Characteristics of Adults With Psychotic Symptomatology Under Involuntary Admission and Readmission for Compulsory Treatment in a Referral Psychiatric Hospital in Cyprus

Socio-demographic and clinical characteristics of adults under compulsory psychiatric treatment, have not been reported adequately in Southern European countries. We investigated the socio-demographic and clinical characteristics of adults with psychotic symptomatology who were involuntarily treated in the acute Mental Health Services in Cyprus. A descriptive cross-sectional study was applied. Data collection (December 2016 to February 2018) achieved via a structured questionnaire including demographic and clinical variables. Census sampling was applied in Cyprus referral center for compulsory psychiatric treatment. The sample included 406 individuals (262 males, 144 females). Approximately 86.2% were single, 77.6% were unemployed, and 24.9% held a bachelor's degree. The most frequent clinical diagnosis was schizophrenia or a relevant psychotic disorder (86.4%). The most frequent admission cause was non-adherence to pharmacotherapy along with disorganized behavior (agitation and/or self-care deficit, and/or aggressive behavior, and/or suicidal behavior) (53.6%). Moreover, 70.7% of the sample reported a positive personal history of mental health problems, while 42.1% reported a positive family history of mental health disorders. Half of the participants (52%) were previously involuntarily admitted for compulsory treatment. Adjusted associations of readmission status were reported with Cypriot ethnicity (OR: 4.40, 95%CI: 2.58-7.50), primary education only (OR: 3.70, 95%CI: 1.64-8.37), readmission due to disorganized behavior along with non-adherence to pharmacotherapy (OR: 10.84, 95%CI: 2.69-43.72), as well as along with substance use (OR: 6.39, 95%CI: 1.52-26.82). Readmission was almost five times more likely to occur due to suicidal behavior (OR: 5.01, 95%CI: 1.09-22.99) compared to disorganized behavior not otherwise specified. Additionally, those with a diagnosis of schizophrenia were more than 12 times more frequently readmitted for compulsory treatment compared to other diagnoses (OR 12.15, 95%CI: 1.04-142). Moreover, the participants with higher secondary education had 54.6% less odds to be involuntarily re-admitted compared to Bachelor degree holders (OR 0.442, 95%CI: 0.24-0.79). A high percentage of involuntary treatment was noted due to non-adherence to pharmacotherapy and substance use. Re-evaluation of the effectiveness of relevant community interventions is suggested, as well as implementation of structured educational programs on therapy adherence during psychiatric hospitalization.

Identification of risk factors for involuntary psychiatric hospitalization: using environmental socioeconomic data and methods of machine learning to improve prediction

BACKGROUND

The purpose of this study was to identify factors associated with a high risk of involuntary psychiatric in-patient hospitalization both on the individual level and on the level of mental health services and the socioeconomic environment that patients live in.

METHODS

The present study expands on a previous analysis of the health records of 5764 cases admitted as in-patients in the four psychiatric hospitals of the Metropolitan City of Cologne, Germany, in the year 2011 (1773 cases treated under the Mental Health Act and 3991 cases treated voluntarily). Our previous analysis had included medical, sociodemographic and socioeconomic data of every case and used a machine learning-based prediction model employing chi-squared automatic interaction detection (CHAID). Our current analysis attempts to improve the previous one through (1) optimizing the machine learning procedures (use of a different type of decision-tree prediction model (Classification and Regression Trees (CART) and application of hyperparameter tuning (HT)), and (2) the addition of patients' environmental socioeconomic data (ESED) to the data set.

RESULTS

Compared to our previous analysis, model fit was improved. Main diagnoses of an organic mental or a psychotic disorder (ICD-10 groups F0 and F2), suicidal behavior upon admission, admission outside of regular service hours and absence of outpatient treatment prior to admission were confirmed as powerful predictors of detention. Particularly high risks were shown for (1) patients with an organic mental disorder, specifically if they were retired, admitted outside of regular service hours and lived in assisted housing, (2) patients with suicidal tendencies upon admission who did not suffer from an affective disorder, specifically if it was unclear whether there had been previous suicide attempts, or if the affected person lived in areas with high unemployment rates, and (3) patients with psychosis, specifically those who lived in densely built areas with a large proportion of small or one-person households.

CONCLUSIONS

Certain psychiatric diagnoses and suicidal tendencies are major risk factors for involuntary psychiatric hospitalization. In addition, service-related and environmental socioeconomic factors contribute to the risk for detention. Identifying modifiable risk factors and particularly vulnerable risk groups should help to develop suitable preventive measures.

Retrospective Chart Review of Voluntary Admissions to an Inpatient Psychiatric Hospital in New York City: A Demographic Breakdown

The current paper evaluates psychiatric needs of voluntary admissions in a large urban psychiatric hospital through a retrospective chart review, as this research is limited within the United States. A total of 581 voluntary adult psychiatric admission charts were reviewed. Continuous variables were evaluated using an ANOVA while associations between variables were examined by an unadjusted Pearson correlation coefficient a stepwise linear regression analysis. Men were significantly more likely to have a past admission for psychiatric services (p = .016), suicidal ideation (p < .001) and test positive for substances (p < .001) than women, and were more likely to be unemployed, homeless and without insurance. Women were more likely to have a past suicide attempt and a depressive disorder. A significant relationship between gender and rationale for seeking voluntary admission (p < .001) was found. This study offers understanding of male and female voluntary admissions, and a foundation for improving treatment interventions to reduce recurrent readmissions.

Clinical and social factors associated with increased risk for involuntary psychiatric hospitalisation: a systematic review, meta-analysis, and narrative synthesis

BACKGROUND

Use of involuntary psychiatric hospitalisation varies widely within and between countries. The factors that place individuals and populations at increased risk of involuntary hospitalisation are unclear, and evidence is needed to understand these disparities and inform development of interventions to reduce involuntary hospitalisation. We did a systematic review, meta-analysis, and narrative synthesis to investigate risk factors at the patient, service, and area level associated with involuntary psychiatric hospitalisation of adults.

METHODS

We searched MEDLINE, PsycINFO, Embase, and the Cochrane Controlled Clinical Register of Trials from Jan 1, 1983, to Aug 14, 2019, for studies comparing the characteristics of voluntary and involuntary psychiatric inpatients, and studies investigating the characteristics of involuntarily hospitalised individuals in general population samples. We synthesised results using random effects meta-analysis and narrative synthesis. Our review follows Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and is registered on PROSPERO, CRD42018095103.

FINDINGS

77 studies were included from 22 countries. Involuntary rather than voluntary hospitalisation was associated with male gender (odds ratio 1·23, 95% CI 1·14-1·32; p<0·0001), single marital status (1·47, 1·18-1·83; p<0·0001), unemployment (1·43, 1·07-1·90; p=0·020), receiving welfare benefits (1·71, 1·28-2·27; p<0·0001), being diagnosed with a psychotic disorder (2·18, 1·95-2·44; p<0·0001) or bipolar disorder (1·48, 1·24-1·76; p<0·0001), and previous involuntary hospitalisation (2·17, 1·62-2·91; p<0·0001). Using narrative synthesis, we found associations between involuntary psychiatric hospitalisation and perceived risk to others, positive symptoms of psychosis, reduced insight into illness, reduced adherence to treatment before hospitalisation, and police involvement in admission. On a population level, some evidence was noted of a positive dose-response relation between area deprivation and involuntary hospitalisation.

INTERPRETATION

Previous involuntary hospitalisation and diagnosis of a psychotic disorder were factors associated with the greatest risk of involuntary psychiatric hospitalisation. People with these risk factors represent an important target group for preventive interventions, such as crisis planning. Economic deprivation on an individual level and at the population level was associated with increased risk for involuntary hospitalisation. Mechanisms underpinning the risk factors could not be identified using the available evidence. Further research is therefore needed with an integrative approach, which examines clinical, social, and structural factors, alongside qualitative research into clinical decision-making processes and patients' experiences of the detention process.

Gender, diagnosis and involuntary psychiatry admission in Ireland: A report from the Dublin Involuntary Admission Study (DIAS)

Involuntary admission and treatment are common, long-standing features of psychiatry but the relationships between gender, diagnosis and other features of involuntary treatment are not clear. We studied all voluntary and involuntary psychiatry admissions at Tallaght University Hospital, Dublin over 2 years (n = 1230). Admission rates in Tallaght were lower than national rates for all admissions (224.9 admissions per 100,000 population per year in Tallaght versus 376.8 nationally), voluntary admissions (194.0 versus 328.4) and involuntary admissions (30.9 versus 48.4). Compared to men, proportionately fewer admissions of admissions of women were involuntary (11% versus 16%) and women were more commonly diagnosed with affective (mood) disorders (29.5% of women versus 22.6% of men), neuroses (anxiety disorders) (14.0% versus 8.8%) and personality and behavioural disorders (18.0% versus 9.2%), and less commonly diagnosed with schizophrenia group disorders (21.8% versus 32.0%), alcohol disorders (2.9% versus 4.3%) and drug disorders (3.6% versus 8.1%). Schizophrenia group disorders accounted for a greater proportion of male (63.2%) than female (55.6%) involuntary admissions, and affective disorders accounted for a greater proportion of female (17.5%) than male (12.3%) involuntary admissions. Duration of admission was independently associated with, in order of strength of association, involuntary status, schizophrenia group disorders and increasing age, but duration of involuntary care was not associated with any of these factors. The chief gender-related features of involuntary psychiatry admission are that (a) proportionately fewer admissions of admissions of women are involuntary compared to men, and (b) diagnoses of affective disorders are more common in women, and schizophrenia group diagnoses more common in men. Future research could usefully explore gender differences in grounds for involuntary detention and police involvement in the involuntary admission process. Future research is also warranted into whether gender associations differ in older compared to younger involuntary patients.

Clinical and socio-demographic characteristics associated with involuntary admissions in Switzerland between 2008 and 2016: An observational cohort study before and after implementation of the new legislation

BACKGROUND

Involuntary admission (IA) for psychiatric treatment has a history of controversial discussions. We aimed to describe characteristics of a cohort of involuntarily compared to voluntarily admitted patients regarding clinical and socio-demographic characteristics before and after implementation of the new legislation.

METHODS

In this observational cohort study, routine data of 15'125 patients who were admitted to the University Hospital of Psychiatry Zurich between 2008 and 2016 were analyzed using a series of generalized estimating equations.

RESULTS

At least one IA occurred in 4'560 patients (30.1%). Of the 31'508 admissions 8'843 (28.1%) were involuntary. In the final multivariable model, being a tourist (OR = 3.5) or an asylum seeker (OR = 2.3), having a schizophrenic disorder (OR = 2.1), or a bipolar disorder (OR = 1.8) contributed most to our model. Male gender, higher age, prescription of neuroleptics (all OR < 2.0) as well as having a depressive disorder, prescription of psychotherapy, prescription of antidepressants and admission after implementation of the new legislation (all OR > 0.6) were also weakly associated with IA.

CONCLUSIONS

Besides schizophrenic or bipolar disorders, a small group of patients had an increased risk for IA due to non-clinical parameters (i.e. tourists and asylum seekers). Knowledge about risk factors should be used for the development of multi-level strategies to prevent frequent (involuntary) hospitalizations in patients at risk. On the organizational level, we could show that the new legislation decreased the risk for IA, and therefore may have succeeded in strengthening patient autonomy.

A retrospective analysis of determinants of involuntary psychiatric in-patient treatment

BACKGROUND

The purpose of our study was to identify predictors of a high risk of involuntary psychiatric in-patient treatment.

METHODS

We carried out a detailed analysis of the 1773 mental health records of all the persons treated as in-patients under the PsychKG NRW (Mental Health Act for the state of North Rhine-Westphalia, Germany) in a metropolitan region of Germany (the City of Cologne) in 2011. 3991 mental health records of voluntary in-patients from the same hospitals served as a control group. We extracted medical, sociodemographic and socioeconomic data from these records. Apart from descriptive statistics, we used a prediction model employing chi-squared automatic interaction detection (CHAID).

RESULTS

Among involuntary patients, organic mental disorders (ICD10: F0) and schizophrenia and other psychotic disorders (ICD10: F2) were overrepresented. Patients treated as in-patients against their will were on average older, they were more often retired and had a migratory background. The Exhaustive CHAID analysis confirmed the main diagnosis to be the strongest predictor of involuntary in-patient psychiatric treatment. Other predictors were the absence of outpatient treatment prior to admission, admission outside of regular service hours and migratory background. The highest risk of involuntary treatment was associated with patients with organic mental disorders (ICD 10: F0) who were married or widowed and patients with non-organic psychotic disorders (ICD10: F2) or mental retardation (ICD10: F7) in combination with a migratory background. Also, referrals from general hospitals were frequently encountered.

CONCLUSIONS

We identified modifiable risk factors for involuntary psychiatric in-patient treatment. This implies that preventive measures may be feasible and should be implemented to reduce the rate of involuntary psychiatric in-patient treatment. This may include efforts to establish crisis resolution teams to improve out-patient treatment, train general hospital staff in deescalation techniques, and develop special programs for patients with a migratory background.

Relapse in involuntary substance treatment: a transversal study

OBJECTIVE

To evaluate the associations between relapse and admissions (voluntary and involuntary) in a sample of patients with substance dependence.

METHODS

This is a cross-sectional study undertaken at a private medical therapeutic community specialised in treating addiction, located in a rural area of São Paulo, Brazil. Sociodemographic characteristics, the University of Rhode Island Change Assessment Scale (URICA), Stages Readiness and Treatment Eagerness Scale (SOCRATES), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) and Structured Clinical Interview for DSM-IV-SCID were used.

RESULTS

Relapse was associated with low family income (P=.006) and contemplation motivational stage (P<0.05). Nevertheless, no significant differences between individuals who were admitted involuntarily (64%) and voluntarily (54%) were observed (P=0.683) in terms of relapses.

CONCLUSIONS

In this sample, the relapse outcome in involuntary admissions was no different from the voluntary ones.

Psychiatric care without consent in France: Does the type of administrative measure chosen differ according to patients' clinical profile?

The French Mental Health Law of 5 July 2011 stipulates that psychiatric patients can be hospitalized in five different ways. Three types of admission for involuntary treatment are defined under "admission at the request of a third party". The first is "psychiatric care at the request of a third party", followed by two "exceptional" admission measures in the case of an emergency ("emergency psychiatric care at the request of a third party") and imminent danger ("psychiatric care in the case of imminent danger"). The aim of this retrospective study was to determine whether the demographic and clinical characteristics of patients involuntarily admitted to psychiatric care in a French regional teaching hospital differed according to the administrative measure enabling this type of placement. We reviewed a sample of admission medical certificates issued between 1 July 2014 and 30 June 30, 2015 at the Tours University Hospital (France) for psychiatric care without consent. We recorded the following patient characteristics. Collected data included the type of care measure, age, gender, and the presence or absence of various clinical syndromes, such as suicidal thoughts and behavioral, depressive, manic or psychotic disorders. Multivariable analysis showed that a psychotic syndrome was a risk factor for hospitalization under "exceptional" measures and a behavioral syndrome for hospitalization under "psychiatric care at the request of a third party". Several clinical profiles emerged, but suicidal thoughts did not appear to be associated with the type of measures taken. In our sample, the choice of measure applied does not appear to rely on the only clinical observation at admission, contrary to what was planned in the Law.

Involuntary psychiatric hospitalization and its relationship to psychopathology and aggression

The current study investigates the relationship between involuntary hospitalization, severity of psychopathology, and aggression. Adult psychiatric inpatients hospitalized from August, 2012 to January, 2013 were evaluated via the Brief Psychiatric Rating Scale (BPRS) and the Overt Aggression Scale (OAS). Individuals were compared regarding voluntariness of hospitalization. Of the 137 hospitalizations in the period, 71 were involuntary (INV). The variables associated with involuntariness were being brought to hospital by ambulance or police, and aggression in the first 24 h of admission. Risk of suicide at admission, and having personal income were associated with voluntariness. The dimensions of the BPRS associated with involuntary hospitalization were activation, resistance, and positive symptoms. Involuntary psychiatric hospitalization was associated with agitation, psychosis and aggression. The data support the indication of involuntary hospitalization for treatment of patients with severe mental illness.

Profiles of the Patient Who Had Compulsory Hospitalization in a District Psychiatric Hospital

OBJECTIVE

It aims to examine the profiles of patients who were treated with compulsory hospitalization between 2011 and 2015 in a district psychiatric hospital.

METHOD

In this retrospective and cohort study, hospital records gathered from 202 adult patients who were treated with compulsory hospitalization in units with a bed between 2011 and 2015 in a district psychiatric hospital were examined. In this study, profiles and socio-demographic features of the patients with compulsory hospitalization were evaluated by 23 closed-end and open-ended questions prepared by researchers. In data analysis, Monte Carlo Chi-square test and number-percentage distribution were used.

FINDINGS

57.4% of examined cases was female and mean average was 38.88±13.06. Of examined cases, 18.8% was people graduated from high school or university and it was detected that 81.7% didn't have any regular job during the compulsory hospitalization. Of which 55.9% has not gotten married and 12.4% was divorced, 48.0% of the population has been living with their parents, sibling or/and their relatives and 17.8% has been living alone or in the nursing home. Of which 59.9% of the cases which were diagnosed with psychosis, 38.1% with psychotic relapse, 22.8% with medication regulation, 22.8% with excitation (expansiveness) and 15.8% having the risk of self-mutilation and damage his/her environment were admitted to compulsory hospitalization. Of these cases, the relative or custodian of 74.2%, employee of nursing home of 9.4%, law-enforcement officers of 5.4% and medical staff of 4.0% gave hospitalization approval. While not having any history for alcohol-substance abuse, it was established that 10.9% of the population had a problematic juridical records. Of the cases, hospitalization of 75.7% came to end with recovery/discharge and 20.3% was over with the demand of his/her relative/custodian, 1.5% of the cases escaped from the hospital.

CONCLUSION

Patients whose majority was female, person who has never gotten married or was divorced and has low educational level don't have any regular job and live with their relatives. In addition, their relatives made the majority of these patients admit to hospital because of the history of psychotic diagnose and psychotic relapses. According to these results, it is recommended that patients will receive an effective treatment in order to protect the right to decide their own treatment.

Sex Differences in Psychiatric Hospitalizations of Individuals With Psychotic Disorders

We aimed to evaluate the association between sex and hospitalization characteristics in psychotic disorders. We identified all acute hospitalizations, between 2010 and 2013, for psychotic disorders in patients younger than 45 and older than 55 years (n = 5411) in the hospital's database. In addition, we identified patients who were prescribed with intramuscular risperidone (n = 280) or clozapine (n = 192) at discharge. The results showed that women younger than 45 years had lower proportions of hospitalizations (33.52% vs. 66.47%) and involuntary hospitalizations (33.85% vs. 45.55%) than did men in the same age group. Women older than 55 years had higher proportions of hospitalizations (57.22% vs. 42.77%) and similar proportion of involuntary hospitalizations. Women younger than 45 years were prescribed similar doses of intramuscular risperidone and lower doses of clozapine (345.8 vs. 380.2 mg) and women older than 55 years were prescribed higher doses of intramuscular risperidone (44.8 vs. 34.4 mg/2 weeks) and clozapine (164.32 vs. 154.5 mg) than were men in the same age group. Women in the reproductive years have better hospitalization characteristics than do men on these measures.

Exploring and explaining involuntary care: The relationship between psychiatric admission status, gender and other demographic and clinical variables

Involuntary admission and treatment are features of psychiatric care in many countries, but the relationship between involuntary status and gender (among other factors) is not clear. We examined demographic and diagnostic factors associated with involuntary admission in a general adult psychiatry service in a deprived area of Dublin's north inner-city over a 7-year period (2008 to 2014 inclusive). Over this period, there were 1099 admissions, yielding an annual admission rate of 504.8 admissions per 100,000 population per year. When adjusted for deprivation, this rate (387.7) was lower than the national rate (413.9). Consistent with other inner-city areas in Dublin, 14.1% of admissions were involuntary, yielding an involuntary admission rate of 71.2 per 100,000 population per year (deprivation-adjusted rate: 54.8), which is higher than the national rate (39.4). After controlling for age, occupation, marital status and diagnosis, the only independent predictors of admission status were place of origin (p<0.001) and male gender (p=0.001). These findings are consistent with studies showing associations between male gender and involuntary status in the United States, New Zealand, Netherlands, Norway, Belgium, France, and Luxembourg. In contrast, female gender is associated with involuntary status in Switzerland, Brazil, and China. These cross-national differences are likely related to differing legal traditions and different criteria for involuntary admission, possibly related to varying emphases placed on "dangerousness" as a mandatory criterion for involuntary hospitalization. This merits further, cross-national study.
