Cannabis Consumers' View of Regulated Access to Recreational Cannabis: A Multisite Survey in Switzerland.

INTRODUCTION: There is considerable effort in legalizing recreational use of cannabis globally. The successful implementation of a program of regulated access to recreational cannabis (PRAC) depends on the consumers' engagement. The aim of this study was to examine the acceptability of twelve different regulatory aspects by cannabis users including those obtaining cannabis from the illicit market and vulnerable populations such as young adults and problematic users. METHODS: The current study is a multisite online survey conducted in Switzerland. A total of 3,132 adult Swiss residents who consumed cannabis within the previous 30 days represented the studied population. Mean age was 30.5 years, 80.5% were men, and 64.2% of the participants stated that they always or often obtain cannabis from the illicit market. We described consumers' acceptability of twelve regulatory aspects concerning THC content control, disclosure of sensitive personal data, security aspects, and follow-up procedures by applying descriptive statistics and multiple regression models. RESULTS: THC content regulation showed most discrepancy with 89.4% of the participants stating to engage in a PRAC if five different THC contents were available as compared to 54% if only 12% THC was available. The least accepted regulatory aspect was disposal of contact details with an acceptability rate of 18.1%. Consumers mainly obtaining cannabis from the illicit market, young adults, and problematic users showed similar acceptability patterns. Participants obtaining cannabis from the illicit market were more likely to engage in a PRAC if five different THC contents were available as compared to participants obtaining cannabis from other sources (OR 1.94, 95% CI: 1.53-2.46). CONCLUSION: A carefully designed PRAC that takes into account the consumers' perspective is likely to transfer them to the regulated market and to engage vulnerable populations. We cannot recommend the distribution of cannabis with only 12% THC content as this is unlikely to engage the target population.

Impaired glutamate homeostasis in the nucleus accumbens in human cocaine addiction.

Cocaine addiction is characterized by overwhelming craving for the substance, which drives its escalating use despite adverse consequences. Animal models suggest a disrupted glutamate homeostasis in the nucleus accumbens to underlie addiction-like behavior. After chronic administration of cocaine, rodents show decreased levels of accumbal glutamate, whereas drug-seeking reinstatement is associated with enhanced glutamatergic transmission. However, due to technical obstacles, the role of disturbed glutamate homeostasis for cocaine addiction in humans remains only partially understood, and accordingly, no approved pharmacotherapy exists. Here, we applied a tailored proton magnetic resonance spectroscopy protocol that allows glutamate quantification within the human nucleus accumbens. We found significantly reduced basal glutamate concentrations in the nucleus accumbens in cocaine-addicted (N = 26) compared with healthy individuals (N = 30), and increased glutamate levels during cue-induced craving in cocaine-addicted individuals compared with baseline. These glutamatergic alterations, however, could not be significantly modulated by a short-term challenge of N-acetylcysteine (2400 mg/day on 2 days). Taken together, our findings reveal a disturbed accumbal glutamate homeostasis as a key neurometabolic feature of cocaine addiction also in humans. Therefore, we suggest the glutamatergic system as a promising target for the development of novel pharmacotherapies, and in addition, as a potential biomarker for a personalized medicine approach in addiction.

'Placement budgets' for supported employment: impact on employment rates in a multicentre randomised controlled trial.

BACKGROUND: The most effective rehabilitation model for job (re-)entry of people with mental illness is supported employment. A barrier to introducing supported employment into standard care is its temporally unlimited provision, which conflicts with health and social legislation in many European countries. AIMS: To test the impact of different 'placement budgets', i.e. a predefined maximum time budget for job seeking until take-up of competitive employment. METHOD: Participants (116) were randomly assigned to 25 h, 40 h or 55 h placement budgets in an intent-to-treat analysis. We applied the individual placement and support model over 24 months, following participants for 36 months. Primary outcome was employment in the labour market for at least 3 months. RESULTS: The proportion of participants obtaining competitive employment was 55.1% in the 25 h group, 37.8% in the 40 h group and 35.8% in the 55 h group. In a Cox regression analysis, time to employment was slightly lower in the 25 h group relative to the 40 h (hazard ratio 1.78, 95% CI 0.88-3.57, P = 0.107) and 55 h groups (hazard ratio 1.74, 95% CI 0.86-3.49, P = 0.122), but this was not statistically significant. The vast majority of all participants who found a job did so within the first 12 months (80.4%). CONCLUSION: A restricted time budget for job finding and placement does not affect the rate of successful employment. In accordance with legislation, a restriction of care provision seems justified and enhances the chances of supported employment being introduced in statutory services.

Long-Term Opioid Agonist Treatment Participation after First Treatment Entry is Similar across 4 European Regions but Lower in Non-Nationals.

Heroin users in opioid agonist treatment (OAT) show markedly reduced heroin consumption, less crime and a lower mortality rate. However, the extent of long-term OAT participation over subsequent treatment episodes remains unclear. We analysed the annual proportion of patients in treatment (at least 1 day) since the start of first OAT in 4 European regions: Barcelona (BA) 1996-2012: 8,602 patients; Czech -Republic (CZ) 2000-2014: 4,377 patients; Netherlands (NL) 1994-2014: 33,235 patients, Zurich (ZU) 1992-2015: 11,795. We estimated the long-term decline of treatment need due to mortality or abstinence and also a "nuisance" short-term decline until the equilibrium level of cycling in and out of OAT is reached to obtain the adjusted treatment participation value. The adjusted treatment participation was around 50% (BA: 47.4-51.4%; CZ: 49.8-53.9%; NL: 52.3-54.0%; ZU: 46.4-49.3%), and the annual decline of treatment need was close to 4%. Non-nationals (NL patients with a migrant background) showed substantial lower adjusted treatment participation (rate ratio BA: 0.059-0.343; NL: 0.710-0.751; ZU: 0.681-0.797; CZ: n.a.). Our method may provide a policy-relevant indicator of long-term provision, quality and access to OAT following first treatment.

Telecommunications Network Measurements of Online Gambling Behavior in Switzerland: A Feasibility Study.

BACKGROUND: Methodological shortcomings of gambling studies relying on self-report or on data sets derived from gambling operators tend to result in biased conclusions. The aim of this study was to analyze online gambling behavior using a novel network database approach. METHODS: From October 13 to October 26, 2014, telecommunications network data from a major telecommunications provider in Switzerland were analyzed. Netflows between mobile devices and a poker operator were quantified to measure the gambling duration and session number. RESULTS: Time spent gambling during night and working hours was compared between devices with longest (red group), intermediate (orange group), and shortest gambling time (green group). Online gambling behavior differed depending on overall gambling time, F (2, 3,143). Night and working hours gambling was the highest in the red group (53%), compared to the orange (50.1%) and the green groups (41.5%). Post hoc analyses indicated significant differences between the orange and green groups (p < 0.05). No differences were observed between the red and orange groups (p = 0.850), and the red and green groups (p = 0.053). CONCLUSIONS: On mobile devices, distinct gambling patterns were observed depending on the overall gambling time. This methodology could also be used to investigate online gaming, social media use, and online pornography.

Predictors of repeat visits to hospital psychiatric emergency departments in Malaga (Spain) and in Lisbon (Portugal).

OBJECTIVE: This study describes the profile of people with mental disorders attending emergency departments (EDs) in two countries and to identify specific mental disorders associated with repeat emergency visits. METHODS: Retrospective analyses of 1 year of EDs data from two hospitals with psychiatric departments, one in Amadora/Sintra (Lisbon, Portugal, 2008) and the other in Malaga (Spain, 2009), were carried out. To determine which mental disorders were associated with repeat visits in each setting, negative binomial models were calculated. RESULTS: There were 5141 visits for a mental disorder made by 3667 patients. Patients with affective disorder were the most frequent (32.2%). Among all mental health patients, 19.9% had at least one repeat visit during the year. For the two EDs setting combined, patients with personality disorders (incidence rate ratio (IRR)=3.79, 95% CI: 2.39 to 6.02) and psychotic disorders (IRR=1.46, 95% CI: 1.13 to 1.89) were more likely to have repeat visits compared with patients with affective disorders, whereas mental disorders due to psychoactive substance use (IRR=0.52, 95% CI: 0.37 to 0.73) was associated with lower likelihood of repeat visits. Nearly all significant differences were attributable to the Malaga sample, where patients with personality disorders were four times more likely to have repeat EDs visits compared with patients with affective disorders. However, at both sites, patients with mental disorders due to psychoactive substance use were less likely to have repeat visits. CONCLUSIONS: Certain mental disorders may be predictive of more frequent ED visits. The different results for each country suggest that further studies might focus not only on the characteristics of patients, but also on local healthcare organisation.

Relationship of suicide rates to economic variables in Europe: 2000-2011.

BACKGROUND: It is unclear whether there is a direct link between economic crises and changes in suicide rates. AIMS: The Lopez-Ibor Foundation launched an initiative to study the possible impact of the economic crisis on European suicide rates. METHOD: Data was gathered and analysed from 29 European countries and included the number of deaths by suicide in men and women, the unemployment rate, the gross domestic product (GDP) per capita, the annual economic growth rate and inflation. RESULTS: There was a strong correlation between suicide rates and all economic indices except GPD per capita in men but only a correlation with unemployment in women. However, the increase in suicide rates occurred several months before the economic crisis emerged. CONCLUSIONS: Overall, this study confirms a general relationship between the economic environment and suicide rates; however, it does not support there being a clear causal relationship between the current economic crisis and an increase in the suicide rate.

Ethnic- and gender-specific differences in the prevalence of HIV among patients in opioid maintenance treatment-a case register analysis.

BACKGROUND: We have sought to identify ethnic- and gender-specific differences in HIV prevalence among heroin users receiving opioid maintenance treatment in the canton of Zurich, Switzerland. METHODS: We used a generalized linear model (GEE) to analyze data from the anonymized case register for all opioid maintenance treatments in the canton of Zurich. Patients who received either methadone or buprenorphine between 1991 and 2012 (n=11,422) were evaluated for gender (male vs. female), ethnic background (Swiss vs. non-Swiss), and lifetime method of drug use (ever injector vs. non-injector). We addressed missing data by multiple imputation. RESULTS: The overall prevalence of HIV among patients declined substantially from 33.7% in 1991 to 10.6% in 2012 in the complete dataset. In the imputed datasets, the respective prevalence dropped from 32.8% in 1991 to 9.7% in 2012. Non-injectors had a four to five times lower risk ratio (RR) compared to the reference group, 'Swiss males who ever injected'. In addition, we found a significantly higher risk ratio of HIV prevalence among females who had ever injected; this was true both for the complete dataset and the imputed dataset (Swiss RR 1.18 CI 95% 1.04-1.34, non-Swiss RR 1.58 CI 95% 1.18-2.12). CONCLUSION: In this population, gender, ethnic background, and lifetime method of drug use influenced the risk of being HIV positive. Different access to treatment and different characteristics of risk exposure among certain subgroups might explain these findings. In particular, the higher risk for women who inject drugs-especially for those with an immigrant background-warrants additional research. Further exploration should identify what factors deter women from using available HIV-prevention measures and whether and how these measures can be better adapted to high-risk groups.

Fine motor skills in adult Tourette patients are task-dependent.

BACKGROUND: Tourette syndrome is a neuropsychiatric disorder characterized by motor and phonic tics. Deficient motor inhibition underlying tics is one of the main hypotheses in its pathophysiology. Therefore the question arises whether this supposed deficient motor inhibition affects also voluntary movements. Despite severe motor tics, different personalities who suffer from Tourette perform successfully as neurosurgeon, pilot or professional basketball player. METHODS: For the investigation of fine motor skills we conducted a motor performance test battery in an adult Tourette sample and an age matched group of healthy controls. RESULTS: The Tourette patients showed a significant lower performance in the categories steadiness of both hands and aiming of the right hand in comparison to the healthy controls. A comparison of patients' subgroup without comorbidities or medication and healthy controls revealed a significant difference in the category steadiness of the right hand. CONCLUSIONS: Our results show that steadiness and visuomotor integration of fine motor skills are altered in our adult sample but not precision and speed of movements. This alteration pattern might be the clinical vignette of complex adaptations in the excitability of the motor system on the basis of altered cortical and subcortical components. The structurally and functionally altered neuronal components could encompass orbitofrontal, ventrolateral prefrontal and parietal cortices, the anterior cingulate, amygdala, primary motor and sensorimotor areas including altered corticospinal projections, the corpus callosum and the basal ganglia.

'Placement budgets' for supported employment--improving competitive employment for people with mental illness: study protocol of a multicentre randomized controlled trial.

BACKGROUND: Vocational integration of people with mental illness is poor despite their willingness to work. The 'Individual Placement and Support' (IPS) model which emphasises rapid and direct job placement and continuing support to patient and employer has proven to be the most effective vocational intervention programme. Various studies have shown that every second patient with severe mental illness was able to find competitive employment within 18 months. However, the goal of taking up employment within two months was rarely achieved. Thus, we aim to test whether the new concept of limited placement budgets increases the effectiveness of IPS. METHODS/DESIGN: Six job coaches in six out-patients psychiatric clinics in the Canton of Zurich support unemployed patients of their clinic who seek competitive employment. Between June 2010 and May 2011 patients (N=100) are randomly assigned to three different placement budgets of 25h, 40h, or 55h working hours of job coaches. Support lasts two years for those who find a job. The intervention ends for those who fail to find competitive employment when the respective placement budgets run out. The primary outcome measure is the time between study inclusion and first competitive employment that lasted three months or longer. Over a period of three years interviews are carried out every six months to measure changes in motivation, stigmatization, social network and social support, quality of life, job satisfaction, financial situation, and health conditions. Cognitive and social-cognitive tests are conducted at baseline to control for confounding variables. DISCUSSION: This study will show whether the effectiveness of IPS can be increased by the new concept of limited placement budgets. It will also be examined whether competitive employment leads in the long term to an improvement of mental illness, to a transfer of the psychiatric support system to private and vocational networks, to an increase in financial independence, to a reduction of perceived and internalized stigma, and to an increase in quality of life and job satisfaction of the patient. In addition, factors connected with fast competitive employment and holding that job down in the long term are being examined (motivation, stigmatization, social and financial situation).

Effectiveness of aripiprazole in the treatment of adult Tourette patients up to 56 months.

OBJECTIVE: Tourette Syndrome (TS) is characterized by motor and vocal tics. Its pharmacological treatment is often a challenge because of the so-called tachyphylactic effects. Aripiprazole has been reported to be effective in small case series with short follow-up periods. METHODS: In a retrospective analysis, we assessed the effect of off-label treatments with aripiprazole in 20 adult patients (mean age 27.4) divided in a group of severely [67 Yale Global Tourette Severity Scale (YGTTS)-total] and moderately (43.3 YGTTS-total) affected patients. TS patients were treated with aripiprazole (mean 11.8 mg daily) and followed for up to 56 months. RESULTS: Applying a random coefficient model, we found a significant benefit resulting from treatment with aripiprazole. This effect was larger in the severely affected patient group in comparison with the moderately affected patient group. The effect was stable over a time period up to 56 months. CONCLUSION: Aripiprazole, a neuroleptic drug of the third generation with a partial D(2) -agonism is effective in moderately and severely affected adult Tourette patients. We add to the current knowledge through our data extending the follow-up interval up to a maximum of 56 months. All available clinical data strongly support the initiation of a double-blind placebo or other neuroleptic substance controlled trial.

[Clinical and social risk factors for the readmission of patients with schizophrenia to psychiatric inpatient care: a long-term analysis]. / Klinische und soziale Risikofaktoren für Wiederaufnahmen in die stationäre Psychiatrie bei Patienten mit Schizophrenie: Eine Langzeitanalyse.

BACKGROUND: In recent years, admission rates to psychiatric inpatient care have steadily increased, whilst the number of beds has progressively decreased, at least in german-speaking countries. A better understanding of risk factors concerning psychiatric readmissions is indispensable in order to avoid unnecessary inpatient treatment. The aim of our study was to test the influence of various clinical and social factors on the time to readmission. METHOD: We analysed data of an observational study considering especially vulnerable patients with schizophrenia (N = 103). We applied multivariate time-hazards models (survival analysis) to examine the predictors of the time to readmission within 12 months. Independent variables were either time-varying (e.g. Needs for care Assessment Scale (NCA)) or time-invariant (e.g. age). RESULTS: About 50% of the patients were readmitted during the observation period, many of them within the first few weeks. In the final models clinical needs, and a social need increased the risk of readmission, whereas the use of neuroleptic medication reduced the risk. There was an interaction effect between social support and time. CONCLUSIONS: Both, clinical and social factors influence the risk of psychiatric readmission. Therefore, the prevention of readmissions should focus on the patients' skills to manage his/her illness and on the social support that the patients receive.

[Usage of inpatient treatments after reduction of inpatient capacities: Supply influences demand]. / Inanspruchnahme stationärer Behandlungen nach Abbau stationärer Kapazitäten: Das Angebot beeinflusst die Nachfrage.

OBJECTIVE: Next to socio-economic factors, subjective need, political and health economiaspects play an important role in the planning of psychiatric structures. The aim of this study was to assess the consequences of a reduction of inpatient capacities fort the usage of psychiatric inpatient care. METHODS: The admissions of inpatients from a region in which the inpatient service has been replaced by the inpatient service from another region in the canton of Zurich, Switzerland, has been analysed. RESULTS: Within the first two years after the omission of the service the admissions of patients with social health insurance policies from the relative sector decreased significantly as compared to the rest of the canton. In contrast to this, admissions of patients with private health insurances from the relative region and from the rest of the canton increased in a similar way. CONCLUSION: It can be stated that in the first time after a reduction of inpatient capacities patients with social health insurance policies do not use inpatient alternatives even when these are easily accessible. This finding is meaningful for the arrangement of alternative offers for this very large group of patients in psychiatric health care planning.

Cannabis use in Switzerland 2015-2045: A population survey based model.

BACKGROUND: Alternative cannabis regulation models are discussed and implemented worldwide. A baseline scenario under the assumption of no policy or market changes may prove useful to forecast cannabis use and treatment demand and evaluate changes in legislation. METHODS: Based on data of the Continuous Rolling Survey of Addictive Behaviours and Related Risks on cannabis use, age, gender and nationality from 2011 to 2015, we used general estimating equation analysis to model lifetime and 30-days prevalence from 2015 to 2045 in Switzerland accounting for demographic trends. RESULTS: Lifetime prevalence of cannabis use is projected to grow from 28.3% (CI 95% 27.8-28.8) in 2015 to 42.0% (CI 95% 41.0-43.0) in 2045. 30-days prevalence would increase slightly from 2.70% (CI 95% 2.53-2.88) to 3.39% (CI 95% 3.11-3.66). Due to population growth, absolute numbers with past 30-day cannabis use are estimated to increase from 202,784 (CI 95% 189,534-216,035) to 314,302 (CI 95% 288,504-340,100). Among those aged under 30 years no substantial change in lifetime and 30-days prevalence of cannabis use is projected. Larger changes are estimated to occur in the age group 30+. The mean age of past 30-day cannabis users would increase for men with Swiss nationality from 30.3 to 38.7 years. DISCUSSION: Population-based survey data and demographic projections can be used to develop baseline scenarios of future cannabis use. Assuming no changes in cannabis legislation, growing absolute numbers of users will likely increase treatment demand. Cannabis use is estimated to increase among the group aged >30 years, which is currently underrepresented in clinical treatment and research. Our findings highlight the need for prospective baseline scenarios to evaluate the impact of legislative changes on cannabis use. Moreover, in Switzerland effective prevention and treatment interventions for cannabis use disorders are required even if cannabis legislation remains unchanged.

Predictors of Employment for People With Mental Illness: Results of a Multicenter Randomized Trial on the Effectiveness of Placement Budgets for Supported Employment.

Background: Individual placement and support (IPS) has proven to be effective for vocational outcomes in people with mental illness. The original concept of IPS requires temporally unlimited provision of support. Using limited placement budgets and investigating factors that predict their effectiveness may inform decisions about resource allocation. Methods: A range of patient characteristics were tested as predictors of employment outcomes in participants who attended six outpatient psychiatric clinics in Switzerland between June 2010 and May 2011. Overall, 116 patients with the full spectrum of psychiatric conditions were randomly assigned and started an IPS intervention, which was provided by three different placement budgets. Support lasted 2 years for those who found a job, and outcomes were repeatedly assessed over 3 years. The intervention ended for those who failed to find competitive employment by the time their placement budget had run out. Results: Of the 15 variables tested, only Global Assessment of Functioning (GAF) and Clinical Global Impression (CGI) scores were predictors for obtaining work (for ≥1 day) and for maintaining it over a longer period (>3 months). Higher GAF and lower CGI scores increased the odds of obtaining employment and keeping it for at least 3 months. Functional role impairment, quality of life, self-esteem, or education level did not predict employment. Conclusion: Our data suggest that, if time-restricted budgets are offered to a wide range of patients, such as those included in this study, better functioning and lower symptom severity at baseline are predictive of better employment outcomes (finding and maintaining work) on the first (competitive) labor market in Switzerland. It remains to be investigated whether this holds true under different environmental factors. Clinical Trial Registration: ISRCTN, trial number: ISRCTN89670872.

One size does not fit all-evolution of opioid agonist treatments in a naturalistic setting over 23 years.

BACKGROUND AND AIMS: Opioid agonist treatment (OAT) is currently the most effective treatment for people with opioid dependence. In most countries, however, access to the whole range of effective medications is restricted. This study aims to model the distribution of different OAT medications within a naturalistic and relatively unrestricted treatment setting (Zurich, Switzerland) over time, and to identify patient characteristics associated with each medication. METHODS: We used generalized estimating equation analysis with data from the OAT register of Zurich and the Swiss register for heroin-assisted treatment (HAT) to model and forecast the annual proportion of opioids applying exponential distributions until 2018 and patient characteristics between 1992 and 2015. RESULTS: Data from 11 895 patients were included in the analysis. Methadone remains the mainstay of OAT, being prescribed to two-thirds of patients. Following its approval, the proportion of HAT increased rapidly and is now constant at 12.16% [95% confidence interval (CI) = 11.15-13.17]. The initial increase of proportions of buprenorphine or slow-release oral morphine (SROM) following their approval for OAT was slower. While in 2014 both medications had a proportion of 10.2% and 10.3%, respectively, our model predicts a further increase of SROM to 19.9% in 2018, with a ceiling level of 25.19% (21.40-28.98%) thereafter. SROM patients display characteristics similar to those treated with methadone; buprenorphine patients show the highest social integration; and HAT patients are the most homogeneous group, with highest mean age, most widespread injecting experience and lowest social integration. CONCLUSIONS: Based on data from Zurich, Switzerland from 1992 to 2015, there is no evidence for an excessive demand for a single medication in a naturalistic and liberal opioid agonist treatment setting. Rather, the specific patient characteristics associated with each medication underline the need for diversified treatment options for opioid dependence.

Estimating heroin epidemics with data of patients in methadone maintenance treatment, collected during a single treatment day.

AIMS: Effects of differing drug policies are difficult to evaluate, because time trends in the spread of heroin use, the most problematic illicit drug world-wide, are unknown in almost all countries. We aimed to develop a simple method to estimate these dynamics with data that can be gathered from patients in substitution treatment within a single day. DESIGN: We tested the assumption that being in substitution treatment on any day depends solely upon individual time since onset of regular heroin use (following a 'general inclusion function'). We used data from the case register for substitution treatments in the canton of Zurich (1992--2004), comprising 9518 patients, to model a 'general inclusion function'. Applying this function, we calculated 30 incidence curves for heroin dependence, each with data of one of 30 randomly chosen treatment days between 1992 and 2004. FINDINGS: Incidence modelling led to 30 similar curves, and therefore our hypothesis was corroborated. Additionally, our approach also revealed a restricted access to substitution treatment in the early 1990s and a decline in demand due to the introduction of heroin-assisted treatment from 1994 onwards. CONCLUSIONS: In the canton of Zurich, the probability of being in substitution treatment can be described by a 'general inclusion function', and therefore dynamics of heroin epidemics can be estimated based on data of a single treatment day. Adaptation of our function to areas with a more restricted access to substitution treatment may permit these estimations also in other regions or countries. Thus, our approach facilitates the urgently needed assessment of the effects of different drug policies.

"Placement Budgets" for Supported Employment-Impact on Quality of Life in a Multicenter Randomized Controlled Trial.

Background: Employment is an important aspect of psychiatric rehabilitation. The objective of this analysis was to explore how quality of life (QoL) may affect the outcome of supported employment and vice versa. Methods: A total of 116 participants with severe mental disorders were randomly assigned to either 25, 40, or 55 h placement budgets, which comprises job coaches' time resources to support a client in finding a job. The intervention followed the individual placement and support model and lasted up to 36 months. Primary outcome was employment in the first labor market for at least 3 months. QoL was assessed 7 times over the entire 36-months observation period using the WHO QoL Bref, which comprises the dimensions physical health, psychological, social relationships, and environment. Results: The three placement budgets did not differentially relate to QoL, but QoL environment showed a significant increase over time across all three groups. Baseline QoL environment weakly predicted subsequent obtainment of employment (F = 4.08, df = 1, p = 0.046, Cohen's d = 0.39). Controlling for baseline QoL, those participants who obtained a job, as compared to those who did not, showed persistent increases in QoL physical health (b = 0.39, p = 0.002, Cohen's d = 0.50) and QoL psychological (b = 0.40, p < 0.001, Cohen's d = 0.47). Conclusion: Obtaining employment in the first labor market improves patients' QoL. Supported employment is a valuable intervention that may benefit patients with severe mental disorder.

Incidence of heroin use in Zurich, Switzerland: a treatment case register analysis.

BACKGROUND: Switzerland has been criticised for its liberal drug policy, which could attract new users and lengthen periods of heroin addiction. We sought to estimate incidence trends and prevalence of problem heroin use in Switzerland. METHODS: We obtained information about first year of regular heroin use from the case register of substitution treatments in the canton of Zurich for 7256 patients (76% of those treated between 1991 and March, 2005). We estimated the proportion of heroin users not yet in substitution treatment programmes using the conditional lag-time distribution. Cessation rate was the proportion of individuals leaving substitution treatment programmes and not re-entering within the subsequent 10 years. Overall prevalence of problematic heroin use was modelled as a function of incidence and cessation rate. FINDINGS: Every second person began their first substitution treatment within 2 years of starting to use heroin regularly. Incidence of heroin use rose steeply, starting with about 80 people in 1975, culminating in 1990 with 850 new users, and declining substantially to about 150 users in 2002. Two-thirds of those who had left substitution treatment programmes re-entered within the next 10 years. The population of problematic heroin users declined by 4% a year. The cessation rate in Switzerland was low, and therefore, the prevalence rate declined slowly. Our prevalence model accords with data generated by different approaches. INTERPRETATION: The harm reduction policy of Switzerland and its emphasis on the medicalisation of the heroin problem seems to have contributed to the image of heroin as unattractive for young people. Our model could enable the study of incidence trends across different countries and thus urgently needed assessments of the effect of different drug policies.

Trends in psychiatric hospitalisation of people with schizophrenia: a register-based investigation over the last three decades.

The number of psychiatric beds has declined considerably in many countries over the past decades. Long-term studies on the impact of these health care changes for the severely mentally ill, however, are still scarce. This epidemiological study investigates the use of inpatient psychiatric services by people with schizophrenia, compared to that by people with other mental disorders. We used psychiatric register data of the Swiss canton Zurich to establish the annual treatment prevalence in the period 1977-2004. For patients with psychoses, the length of inpatient episodes decreased by half. The annual number of inpatient admissions doubled. The proportion of schizophrenia patients, which accounted for 36%-41% of all inpatient treatments up to 1993, dropped to 20% in 2004, while that of other psychoses remained about the same (8%-10%) throughout the study period. This contrasts with a 2-3 fold increase in other patient groups. The annual treatment prevalence for people with schizophrenia declined from 7.3 to 2.2 per 10000 population since the 1990s and affected patients of all ages and of both sexes equally. The treatment prevalence for other psychoses remained virtually unchanged (1.3 per 10000). For all other mental disorders, there was an up to twofold increase. The study suggests that the downsizing of psychiatric hospitals has resulted in a far-reaching redistribution of overall inpatient treatment resources. The considerable decrease in inpatient treatment for people with schizophrenia emphasizes the need to further investigate the current state of coverage for and the appropriateness of health care available to this patient group.
