Abstract

Background

Legislation and practice of involuntary hospital admission vary substantially among European countries, but differences in outcomes have not been studied.

Aims

To explore patients' views following involuntary hospitalisation in different European countries.

Method

In a prospective study in 11 countries, 2326 consecutive involuntary patients admitted to psychiatric hospital departments were interviewed within 1 week of admission; 1809 were followed up 1 month and 1613 3 months later. Patients' views as to whether the admission was right were the outcome criterion.

Results

In the different countries, between 39 and 71% felt the admission was right after 1 month, and between 46 and 86% after 3 months. Females, those living alone and those with a diagnosis of schizophrenia had more negative views. Adjusting for confounding factors, differences between countries were significant.

Conclusions

International differences in legislation and practice may be relevant to outcomes and inform improvements in policies, particularly in countries with poorer outcomes.

Throughout the world significant numbers of people are admitted involuntarily to psychiatric hospital departments. How involuntary hospital admissions should best be legislated for and regulated is controversial. Reference Zinkler and Priebe1Reference Welsh and Deahl3 In the UK, the government has proposed two bills for a new mental health act in England and Wales since 2002. Following the wide resistance of professional groups, user organisations and parts of the media, both bills were withdrawn and the government settled for an amendment to the existing 1983 Act. Reference Zigmond4,Reference Tilley and Chambers5

The debate on the most appropriate regulations and practice for involuntary hospital admission is guided by little, if any, research. There is no evidence about whether specific procedures are associated with different outcomes. Reference Katsakou and Priebe6,Reference Kallert, Glöckner and Schutzwohl7 Ethical and practical reasons may prevent experimental designs such as randomised controlled trials. In their absence, observational comparisons between sites with different legislation and practice are a viable method to explore the link between procedures and outcomes.

Countries across Europe share a similar background in terms of societal systems and history of psychiatry but vary substantially in their legislation for and practice of involuntary hospital admission. Reference Felthouse and Sass8,Reference Kallert and Torres-Gonzalez9 Involuntary admission rates vary by a factor of more than 10. Reference Zinkler and Priebe1,Reference Kallert, Rymaszewska and Torres-Gonzalez10 Several studies have analysed the differences in legislation and policies but there is no evidence yet on whether there also are differences in outcomes.

Legislation for involuntary admissions is based on the assumption that individuals cannot recognise the need for hospital care because of the severe and usually acute symptoms of their illness. This would imply that they should later (once the acute phase is over) accept that the involuntary admission was the right intervention at the time. Reference Beck and Golowka11 Patients’ retrospective view of the appropriateness of the admission has been used as an outcome criterion in studies in Australia, Canada, Sweden, the USA and the UK. Reference Spence, Goldney and Costain12Reference Rusius18 Between 33 and 81% of involuntary patients found the admission ‘right’ in retrospect. The rate varied according to the exact wording of the question and the time since admission. Reference Katsakou and Priebe6

In this study we assessed patients' views on involuntary hospital admission after 1 and 3 months at sites in 11 European countries. We explored whether, and if so, to what extent, patients' retrospective views on admission varied between sites in different countries, whether these differences held true after controlling for differences in patient characteristics and what baseline patient characteristics were associated with more or less positive views across countries.

Method

Design and participants

The study was conducted as a multicentre prospective cohort study in 11 European countries: Bulgaria (Sofia), Czech Republic (Prague), Germany (Dresden), Greece (Thessaloniki), Italy (Naples), Lithuania (Vilnius), Poland (Wroclaw), Slovakia (Michalovce), Spain (Granada and Malaga), Sweden (Örebro) and the UK (east London). Between one and five hospitals were studied in each country. Tel Aviv in Israel was originally included, but omitted from this analysis because of inadequate study implementation. All sites had in-patient units with voluntary as well as involuntary patients. Involuntary admissions were conducted according to national legislation and routine practice. The rationale and methods of the study, the characteristics of the participating hospitals and data about other mental health services in the catchment areas of the hospitals have been described in detail elsewhere. Reference Kallert, Glöckner, Onchev, Raboch, Karastergiou and Solomon19 The inclusion criteria were: all in-patients in general psychiatric departments; admitted involuntarily; aged between 18 and 65 years; resident in the catchment area; with sufficient command of the national language; able to give informed consent. Exclusion criteria were: admission because of intoxication; primary diagnosis of dementia; transfer from another hospital.

Procedures and measures

Patients were identified by researchers through ongoing contacts with clinical staff on the wards and the relevant administrators. Clinical staff in the participating wards introduced eligible patients to a researcher, who contacted the patient within the first week of admission, provided a full explanation of the study, and asked for consent. If written informed consent was obtained, the patient was assessed. This included an assessment of psychopathological symptoms, which were taken as baseline symptom levels. Further face-to-face interviews were conducted at follow-up at 1 and 3 months after admission. Patients were recruited between July 2003 and October 2005.

The primary outcome was the patients' retrospective view on the extent to which the admission was right or wrong at 1 and 3 months. Patients rated their response to the question ‘Today, do you find it right or wrong that you were admitted to hospital?’ on an 11-point Likert scale ranging from 0 (entirely wrong) to 10 (entirely right), which has been used in previous research. Reference Kjellin, Westrin, Eriksson and Alexsson-Ostman14,Reference Kjellin, Anderson, Bartholdson, Candefjord, Holmstrom and Jacobsson15

Baseline sociodemographic and clinical characteristics and the diagnosis of the patients were obtained from medical records. These included data on age, gender, living situation (living alone v. living with others), employment situation (no current employment v. employment), previous hospitalisations (none v. one or more previous hospitalisations) and clinical diagnosis according to ICD–10. 20 Diagnoses were collapsed into three groups: schizophrenia or other psychosis (F20–29), affective disorder (F30–39), and ‘others’. Researchers assessed baseline symptom levels on the 24-item version of the Brief Psychiatric Rating Scale (BPRS) Reference Ventura, Green, Shaner and Liberman21 which ranges from 24 to 168, with 168 indicating the maximum symptom severity. Researchers from all sites had joint training sessions in administering and rating this instrument and achieved an interrater reliability (intraclass correlation coefficient) of 0.78. The study was approved by the relevant national and/or local ethics committees.

Statistical analysis

The outcome variable was the patients' retrospective view on the extent to which the admission was right or wrong on an 11-point scale (0, entirely wrong; 10, entirely right), and was treated as quantitative in the analysis to fully utilise the variation in patient's responses and summarised by mean and standard deviation after examining its distribution. To present the primary outcome in each country in a clinically more meaningful manner, we also dichotomised the scale at five (the neutral middle point) and show the percentage of patients who rated above five indicating that they viewed their admission as more right than wrong. Descriptive summary statistics were also used to describe the distributions of the predictors of the outcome variable.

To account for possible correlations among repeated measurements, a generalised estimating equation (GEE) model was employed Reference Liang and Zeger22 with patients' characteristics measured at baseline and time of measurement as fixed effects and patient as random effect. We performed GEE model analysis in three steps. First, we performed a univariate GEE model analysis for all predictors. Predictor variables that were significant at P = 0.05 were subsequently entered in a multivariate GEE model analysis in the second step. Finally, we checked model assumptions by examining the residual plots.

The estimated effects of predictors on the primary outcome from the GEE models are reported together with their 95% confidence intervals. To identify the between-country differences, we derived a matrix of P-values for all possible pair-wise between-country comparisons from the estimated multivariate GEE model.

In England, age, gender, and clinical diagnosis were obtained for all eligible patients in the study including those who were not interviewed (approved by the Patient Information Advisory Group; ref: PIAG 2-10(d)/2005). Interviewed and non-interviewed patients were compared on the assessed characteristics to estimate a potential selection bias in the recruitment process.

At the English site, baseline data were obtained for 181 out of those 183 patients who were eligible but not interviewed. Their mean age was 36.01 years (s.d. = 11.41). Of these, 40% were female, 60% diagnosed with schizophrenia, 22% with affective disorders and 18% with ‘other’ diagnoses. The interviewed and non-interviewed patients were similar on the tested characteristics listed in Table 2.

The baseline characteristics of patients in the total sample followed up at 1 month (and at 3 months) were: 45.1% (45.5%) female; 73.1% (72.2%) unemployed; 35.3% (36.0%) living with others; 71.4% (72.3%) with a previous hospitalisation; 65.7% (64.7%) diagnosed with schizophrenia, 16.7% (17.2%) with affective disorders and 17.6% (18.1%) with ‘other’ diagnoses. The mean age of those followed up at 1 month was 38.87 years (s.d. = 11.21), and of those followed up at 3 months 39.10 years (s.d. = 1.13). The baseline BPRS mean score of those followed up at 1 month was 54.77 (s.d. = 15.84) and of those followed up at 3 months 55.08 (s.d. = 15.84). The assessed characteristics of the originally recruited sample and the samples followed up at 1 and 3 months were similar.

Patients' views on the appropriateness of their involuntary admission show significant differences between sites in different countries, even when adjusted for other predictor variables. The post hoc comparisons show that not all differences between sites in different countries were statistically significant, but the more substantial ones were, for example, patients' views in England are significantly less favourable than those in Bulgaria, Greece, Spain, the Czech Republic, Italy, Germany and Slovakia, whereas patients' views in Slovakia are significantly more positive than in all sites other than those in the Czech Republic, Italy and Germany.

All predictor variables considered further other than previous hospitalisation showed significant associations with outcomes in univariate analyses. In the multivariate analysis however, only gender, living situation and diagnosis were significantly associated with patients' views. Male patients and those living with others tended to find the admission more often right. Patients with schizophrenia had more negative views than those with other diagnoses.

Discussion

Main findings

One month after involuntary hospital admission, between 39 and 71% believed the admission was right. After 3 months, when the acute phase of the mental illness justifying the involuntary admission should be overcome for most patients, the rates are higher and range between 46 and 86%. The findings that a substantial proportion of patients do not agree retrospectively with the appropriateness of the admission may shed a critical light on the ethical justification of involuntary hospital admission. At the same time, an average of 63% found the admission right 3 months later which may be a reassuring finding for many clinicians, patients and their families. The figures are consistent with previous studies with smaller samples and usually less systematic methods. Reference Katsakou and Priebe6,Reference Kjellin, Westrin, Eriksson and Alexsson-Ostman14,Reference Kjellin, Anderson, Candefjord, Palmstierna and Wallsten23,Reference Priebe, Katsakou, Amos, Leese, Morriss and Rose24 However, what is a totally new finding is the large variation across sites in different European countries. This variation is not explained by differences in sociodemographic characteristics, clinical diagnoses or baseline symptom levels considered in this study. The size of the differences are substantial, and many of them are statistically significant.

Strengths and limitations

This is the largest prospective study on outcomes of involuntary hospital admissions ever conducted and the first one to use the same methods across sites in a number of countries. It included centres in 11 European countries with different legislation and practice in involuntary admission. All patients were assessed face to face by trained researchers, and were recruited and interviewed within the first week of admission, which is challenging given that many patients had high symptom levels and all of them were in the hospital on an involuntary basis.

The study has a number of weaknesses: overall, only 50% of the eligible patients were interviewed, and the rate varied across countries. The rate may be seen as low in many other fields of health research, but has been described as good for these types of studies in acute settings with patients who are difficult to recruit. Reference Katsakou and Priebe6 For comparison of recruited and non-recruited patients, data were only available for the English site, although both the followed up and non-followed up patients were compared at all sites. These comparisons did not suggest a selection bias on the assessed characteristics, neither for the recruitment of eligible patients nor for the follow-ups. However, only a few characteristics were assessed.

We only studied between one to five hospitals in each country and do not know to what extent the data are representative for the country as a whole. In England we have data from a linked national study to estimate this. Reference Priebe, Katsakou, Amos, Leese, Morriss and Rose24 The English sites in this international study were two hospitals in the London boroughs of Hackney and Newham. In 20 other hospitals, the same outcome data were assessed in 371 involuntary patients at 1 month and in 307 patients at 3 months. At 1 month, 45% (n = 166) of patients felt that the admission was right (mean score 4.81, s.d. = 3.99), and at 3 months 50% (n = 154) expressed that view (mean score 5.34, s.d. = 3.94). Outcomes at the two study-site hospitals in east London and the 20 other hospitals in England were similar, and using the data of those 20 hospitals would not have substantially changed the findings of the national comparisons. However, there are no similar data from other countries to check whether the results at the study sites are representative for or different from the outcomes at other hospitals in the country.

Possible reasons for the differences

Can the identified differences in patients' views about involuntary admission be linked to the characteristics of the given legislation? There is no straightforward answer. The legislation in all countries is complex and has many features that are of potential importance. Any interpretation of the findings from the identified differences with the characteristics of the national legislation is a post hoc exercise and inevitably speculative.

One possible criterion to classify the national regulations is the extent to which they protect the rights and interests of the patients concerned. Reference Felthouse and Sass8,Reference Kallert and Torres-Gonzalez9 Seven criteria that vary between countries and may be seen as relevant for the protection of the interests of the patients are shown in the Appendix. Although the answers to the questions are not always clear cut, we established the number of criteria for each country. The resulting ranking has similarities with the order of outcomes in the multivariate analysis of this study (with the most protective legislation and most positive patient views in Slovakia and Germany, and the least protective legislation and most negative views in England), but the criteria still leave many of the differences in patients' views unexplained.

A number of other national features might be important. These include the geographical position and political history (e.g. Western v. Eastern Europe), the relative expenditure of healthcare funding on mental healthcare, 25 the overall rates of involuntary admissions, Reference Salize and Dressing2 and the recruitment and follow-up rates in this study. However, none of these was clearly associated in our study with the differences identified in patients' views. There are three other possible factors accounting for the differences that were not assessed. First, patients at the various sites may have differed in relevant social or clinical characteristics that were not captured in the study. Second, national differences in the expectations of patients and overall rating tendencies may have favoured more or less positive answers to the outcome question. Finally, clinical practice (the behaviour of professionals towards involuntary patients and the methods employed to support and treat them) is likely to vary across Europe and impact on outcomes. Some aspects of clinical practice may be linked to national cultures and traditions and difficult to change, but others may reflect training and policies that are transferable to other countries.

Factors associated with outcomes across countries

Some patient characteristics were associated with views on admission across countries. Females expressed more negative views, as has been reported for other patient-reported outcomes in psychiatry, although this is not a consistent finding. Reference Lehman26,Reference Vandiver27 Patients living alone more often rated the admission as wrong, which may reflect their difficulties adjusting to the confined space and the often tense atmosphere with fellow patients and staff on a ward. It may also be that patients living with others had often experienced conflicts and tension with these making the admission a relief and therefore the right decision in retrospect. During and after hospital treatment they are likely to have had discussions with their partners about their illness and received support from them. Both discussions and support may have led to more positive appraisals of the admission. Patients with schizophrenia had more negative views on admission, which may be linked to a more frequent lack of insight in these patients. Reference Dinos, Stevens, Serfaty, Weich and King28 In the multivariate analysis, the degree of baseline symptoms was not associated with later views about the admission. Thus, this study provides no evidence for the assumption that a high level of initial symptoms is associated with more negative views about admission later.

Implications

The findings suggest that the great differences in the legislation and practice of involuntary hospital admission and subsequent treatment across Europe may indeed be associated with substantial differences in patients' views. Although the exact causal factors and mechanisms remain poorly understood, the differences between European countries appear to matter for outcome. Reference Priebe, Frottier, Gaddini, Kilian, Lauber and Martínez-Leal29 Future in-depth studies could identify those factors in legislation and practice that are specifically relevant to achieving more positive views from patients. Reference Katsakou and Priebe30 Countries with currently less favourable outcomes, such as England, might consider implementing them, and methods may be developed to strengthen these factors and improve outcomes across all countries.

Appendix

Criteria to distinguish the legislation on involuntary hospital admission with respect to the protection of the interest of the patients

For each question the first option is seen as more protective of the interest of the patients.

Legislation criteria

  1. (a) Is involuntary admission possible only when patients pose a risk to themselves and/or others, or also to avoid a more general threat to the patients' health?

  2. (b) Can the admission be initiated only by authorities and medical doctors or also by other stakeholders?

  3. (c) Does involuntary admission require the decision of a court or not?

  4. (d) Is the period of time for which the hospital can decide to keep patients involuntarily on the wards without a formal decision for involuntary treatment shorter or longer than 24 hours?

  5. (e) Is legal support guaranteed or not?

  6. (f) With respect to appeal procedures to independent bodies, are there binding time periods for a response, and are people and/or institutions other than the patient authorised to appeal, or not?

  7. (g) Is the decision for involuntary treatment measures separate from the decision for involuntary admission or not?

Criteria protecting the interest of the patients in each country

Seven: Germany (a–g).
