Horizontal flow aerated constructed wetlands for municipal wastewater treatment: The influence of bed depth

The influence of bed depth on the performance of aerated horizontal constructed wetlands was investigated at the pilot plant scale. Two horizontal flow subsurface constructed wetlands (HF) intensified units of different bed depth (HF1: 0.90 m and HF2: 0.55 m, 0.8 m and 0.5 m water level, respectively) were fitted with forced aeration, while a third one (HFc, 0.55 m bed depth, 0.5 m water level) was used as control and not aerated. The three HF units were operated in parallel, receiving the same municipal wastewater pre-treated in a hydrolytic up-flow sludge blanket anaerobic digester. Applied surface loading rates (SLR) ranged from 20 to 80 g biochemical oxygen demand (BOD5)/m2·d and from 3.7 to 6.7 g total nitrogen (TN)/m2·d, while it ranges from 6 to 23 g BOD5/m2·d and from 1.1 to 1.7 g TN/m2·d in the control unit. Removal of total suspended solids (TSS) and BOD5 was usually close to a 100 % in all units, whilst chemical oxygen demand (COD) removal was higher for the HF1 unit (97 % on average, range of 96-99 %) than for HF2 (92 %, 82-98 %) and HFc (94 %, 86-99 %). TN removal reached on average 33 % (16-43 %) in HFc, 37 % (10-76 %) in HF2 and 51 % (21-79 %) in HF1. High TN removal required a longer aeration time for nitrification and higher effluent recirculation ratio to enhance denitrification. The results indicate that artificial aeration and a high bed depth allows to increase the SLR by a factor of 4 in HF1 but only by a factor of 2 in HF2.

An approach to identify people with mental illness that can be expected to benefit from integrated community care in Germany

Introduction

Although integrated community care programs specifically tailored to patients with severe mental illness (SMI) are available, recent studies show that these programs are not always provided to the population which would benefit the most from it.

Objectives

Aims of this study were the selection of clinical and psychosocial characteristics and the development of a screening algorithm indicating the need for integrated community care services in people with mental disorders.

Methods

Data of an observational longitudinal study including N=511 participants has been used to examine the hypothesized determinants. At baseline, self-reported empowerment has been assessed via the EPAS and psychosocial impairment and perceived needs have been rated by research workers via the HoNOS and the CAN, respectively. Use of integrated community care services was defined as at least four appointments with service providers over six months and has been recorded via the CSSRI twelve to 18 months after baseline. Mixed-effects regression analyses have been performed to test the predictive value of the hypothesized determinants and marginal predictions were used to define cut-offs for the assessment tool.

Results

EPAS, HoNOS and CAN scores each proved to be significant predictors for using integrated community care services. Cut-off scores for each predictor are presented, forming practical assessment guidelines for future studies.

Conclusions

A screening tool and an algorithm for the identification of mentally ill patients who can be expected to benefit from integrated community mental health care programs is available for the German health care system.

Impact of the COVID-19 pandemic on mental health and service use of people with severe mental illness

Introduction

The COVID-19 pandemic has a huge impact on the provision of mental health care. Particularly the limitations of face-to-face contacts and the access to treatment facilities can be expected to have significant negative effects on the practice of psychiatric treatment and outcomes. To date the extent and the severity of these effects in people with severe mental illnesses are rarely investigated in Germany.

Objectives

We investigated the impact of the COVID-19 pandemic on mental health and service use of people with severe mental illness in Germany.

Methods

As part of a pragmatic randomized trial on the effectiveness of an integrated community mental health care program that started immediately after the first COVID-19 wave in June 2020, 1000 people with severe mental illness from different regions in Germany have been asked for the effects of the COVID-19 pandemic on their mental health care and on their general living conditions. Multivariate regression models were computed to estimate the effects of the patients’ COVID-19 experiences on the outcome parameters empowerment (EPAS), psychosocial impairment (HoNOS) and unmet needs (CAN).

Results

Using prospective data in a large sample of people with mental illness, we will be able to examine the extent to which the pandemic has affected participants’ mental health, their social lives, but also the use of mental health care services.

Conclusions

The data will help to examine the impact of the pandemic on people with severe mental illness in a comprehensive way and will provide evidence where immediate action is needed to reduce further burdens and inequities.

Results of a factor analysis of items regarding COVID-19 pandemic-specific workload among medical staff in Germany

Introduction

Epidemics lead to an increase in occupational stress and psychological strain among medical staff (cf. Mulfinger et al. 2020). However, there are no validated questionnaires to measure stress caused by an epidemic such as Covid-19, instead self-constructed questions are used frequently.

Objectives

The aim was to develop items for the assessment of specific workload in epidemics which can be used to obtain longitudinal data.

Methods

A sample of N=8078 persons working in the health care sector in Germany participated in the VOICE, EviPan online survey addressing the burden of Covid-19 pandemic during the 2nd quarter of 2020. We used 15 self-constructed items to examine whether these items can represent Covid-19 specific topics. A total of N=7549 (24% males) had complete data to run a confirmatory factor analysis using SEM procedure in Stata 14.2.

Results

Five factors were identified a priory: Factor (F) 1: Workload due to Covid-19 pandemic (4 items; Cronbachs’ alpha (α))=0.740); F 2: Fear, uncertainty of SarsCoV-2infection (self and others) (3 items; α= 0.741); F 3: Patient safety (3 items; α=0.533; F 4: Perception of protection concepts (2 items; α=0.590); F 5: Dysfunctional coping strategies (3 items; α=0.447). Fit-Indices: χ²(73)= 1373.849, p<.001, CFI=.946, TLI=.923, RMSEA=.0049, SRMR=.037)

Conclusions

We identified 5 factors associated with problems occurring during the Covid-19 pandemic with acceptable to good internal consistency. Most of the constructed items could therefore be used in further surveys to monitor stress, as a basis for recommendations in the area of stress prevention and interventions for medical staff during epidemics.

Effectiveness and cost effectiveness of a stress management training for leaders of small and medium sized enterprises - study protocol for a randomized controlled-trial

BACKGROUND

Leaders in small and medium-sized enterprises (SMEs) are exposed to increased stress as a result of a range of challenges. Moreover, they rarely have the opportunity to participate in stress management trainings. Therefore, KMU-GO (ger: Kleine und mittlere Unternehmen - Gesundheitsoffensive; en: small and medium-sized enterprises - health campaign) aims at conducting and evaluating such a stress management training. The focus of evaluation does not only lie on the effects on leaders participating but also on their employees.

METHODS

The study is planned as a 2 × 3 mixed design with two groups (intervention and waiting control group) as a between factor and point in time (at baseline, 6 and 12 months later) as a within factor. We aim at collecting data from N = 200 leaders. Based on the results of a preceding assessment, an already successfully implemented stress management training was adapted to SME needs and now serves as the framework of this intervention. The stress management training comprises one and a half days and is followed by two booster sessions (each 180 min) about 3 and 6 months after the training. The main focus of this intervention lies on specifying leaders stress reactivity while at the same time investigating its effects on employees' mental health. Further dependent variables are leaders´ depression and anxiety scores, effort-reward imbalance, sick days and psychophysiological measures of heart rate variability, hair cortisol, and salivary alpha-amylase. Cost-effectiveness analyses will be conducted from a societal and employers' point of view.

DISCUSSION

Stress management is a highly relevant issue for leaders in SMEs. By providing an adequate occupational stress management training, we expect to improve leaders´ and also employees` mental health, thereby preventing economic losses for SMEs and the national economy. However, collecting data from employees about the success of a stress management training of their leader is a highly sensitive topic. It requires a carefully planned proceeding ensuring for example a high degree of transparency, anonymity, and providing team incentives.

TRIAL REGISTRATION

The KMU-GO trial is registered at the German Clinical Trial Register (DRKS): DRKS00023457 (05.11.2020).

Do caregivers' perspectives matter? Working alliances and treatment outcomes in trauma-focused cognitive behavioural therapy with children and adolescents

Background: Caregivers play a key role in the success of trauma-focused cognitive behavioural therapy (TF-CBT). Yet, the effect of their alliance on treatment outcomes besides the other parties in treatment has hardly been studied. Objective: This study examined the working alliance (WA) of therapists, patients and caregivers in TF-CBT and its contribution on treatment outcome over time. Methods: N = 76 children and adolescents (mean age = 12.66 years, range 7-17, M/F ratio: .43) participated in the TF-CBT arm of a randomized controlled trial. The WA was assessed with the Working Alliance Inventory Short Version (WAI-S) at two measurement points, while symptom level of posttraumatic stress symptoms (PTSS) was assessed with the Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA). Paired sample t-tests, intraclass correlations (ICC), and mixed-effects regression models for longitudinal data were performed. Results: The alliance rating was high across all informants, with caregivers achieving the highest rating. The average level of cross-informant agreement on the alliance was low between therapists and caregivers (ICC = .26) and moderate between therapists and patients (ICC =.65). A significant contribution of an alliance improvement to the reduction of PTSS over time was found in each of the two tested models: therapists with patients model (b = .682) and therapists with caregivers model (b = .807). However, these effects were not detected with all four perspectives in one comprehensive model. Conclusion: In summary, the potential of caregivers' views should receive more attention in the therapeutic process of trauma-focused therapy.

[Quality of life among older informal caregivers of people with dementia]

BACKGROUND

In Germany, informal caregiving becomes an increasingly important issue especially for people with dementia. Spouses often provide nursing care due to the limited daily living skills of people with dementia. This leads to a wide range of caregiver burden and decreased quality of life (QoL). Analyses on the relation between QoL and caregiver burden of older informal caregivers in Germany are rare.

OBJECTIVE

The following research questions were assessed: (1) Does caregivers' QoL differ from that of the older general population?; (2) Which sociodemographic, health- and care-related characteristics affect caregivers' QoL?

MATERIAL AND METHODS

For this study, two samples (aged 60 years and older) were recruited: informal caregivers (n = 119) and a representative sample of older non-caregivers in the general population (n = 1133). Linear regression analyses were applied to examine the effects of sociodemographic, health and care-related variables on the QoL of older informal caregivers of people with dementia.

RESULTS

Older informal caregivers reported a significantly lower QoL compared to older non-caregivers in the general population. Especially the domains autonomy, activities in the past, the present and the future as well as intimacy were negatively associated with caregivers' QoL.

CONCLUSION

The results of the study highlighted caregivers' need for assistance. Due to demographic changes, tailored support services should be based on older caregivers' needs.

Constructed wetlands and solar-driven disinfection technologies for sustainable wastewater treatment and reclamation in rural India: SWINGS project

SWINGS was a cooperation project between the European Union and India, aiming at implementing state of the art low-cost technologies for the treatment and reuse of domestic wastewater in rural areas of India. The largest wastewater treatment plant consists of a high-rate anaerobic system, followed by vertical and horizontal subsurface flow constructed wetlands with a treatment area of around 1,900 m² and a final step consisting of solar-driven anodic oxidation (AO) and ultraviolet (UV) disinfection units allowing direct reuse of the treated water. The implementation and operation of two pilot plants in north (Aligarh Muslim University, AMU) and central India (Indira Gandhi National Tribal University, IGNTU) are shown in this study. The overall performance of AMU pilot plant during the first 7 months of operation showed organic matter removal efficiencies of 87% total suspended solids, 95% 5-day biological oxygen demand (BOD₅) and 90% chemical oxygen demand, while Kjeldahl nitrogen removal reached 89%. The UV disinfection unit produces water for irrigation and toilet flushing with pathogenic indicator bacteria well below WHO guidelines. On the other hand, the AO disinfection unit implemented at IGNTU and operated for almost a year has been shown to produce an effluent of sufficient quality to be reused by the local population for agriculture and irrigation.

Sources of Meaning in Family Caregivers of Terminally Ill Patients Supported by a Palliative Nursing Care Team – A Naturalistic Three-month Cohort Study

Objectives

To identify possible change patterns or robustness in sources of meaning in family caregivers of pre-terminal patients after onset of support at home by an outreach palliative nursing team during a survey period of three months.

Methods

One hundred caregivers of terminally ill patients were included in a prospective observational trial. The Sources of Meaning and Meaning in Life Questionnaire (SoMe) was administered at four points of measurement: T0 (immediately before onset of palliative care); T1 (one week after T0); T2 (one month after T0); T3 (three months after T0). Descriptive statistics, random effects regression analyses; multivariate linear and quadratic regression models were performed for the full (n = 100) as well as for the reduced sample (n = 24).

Results

Growth curve analyses reveal significant parabolic changes for the dimension “order” and for the subscales “social commitment”, “tradition”, “morality”, and “fun”. All other dimensions or subscales remained stable during the time of the study. Cross-sectional multivariate regression models (T0) showed negative associations of some dimensions with patients’ age and psychological burden of the family caregiver while psychological burden of patients was found to be positively associated with some dimensions. No significant effects of interaction variables with time (linear and quadratic).

Conclusions

With few exceptions, family carers seem to keep a stable sense of meaning in life during the final stage of their relatives’ terminal illness. Particular associations between sources of meaning and age of patients as well as psychological burden both of patients and carers have to be taken into consideration in support planning.

Policies, guideline implementation and practice change - how can the process be understood?

Politics and policy: It is important to understand why, in the translational continuum from pilot research and randomised controlled efficacy trials to roll-out programmes and routine effectiveness studies, some service innovations are taken up by health service purchasers and providers, while others are not. Why do some innovative interventions or models of care get to the stage of implementation, while others fail to be funded?

Hydrolytic anaerobic reactor and aerated constructed wetland systems for municipal wastewater treatment - HIGHWET project

The HIGHWET project combines the hydrolytic up-flow sludge bed (HUSB) anaerobic digester and constructed wetlands (CWs) with forced aeration for decreasing the footprint and improving effluent quality. The HIGHWET plant in A Coruña (NW of Spain) treating municipal wastewater consists of a HUSB and four parallel subsurface horizontal flow (HF) CWs. HF1, HF2 and HF3 units are fitted with forced aeration, while the control HF4 is not aerated. All the HF units are provided with effluent recirculation, but different heights of gravel bed (0.8 m in HF1 and HF2, and 0.5 m in HF3 and HF4) are implemented. Besides, a tobermorite-enriched material was added in the HF2 unit in order to improve phosphorus removal. The HUSB 76-89% of total suspended solids (TSS) and about 40% of chemical oxygen demand (COD) and biological oxygen demand (BOD). Aerated HF units reached above 96% of TSS, COD and BOD at a surface loading rate of 29-47 g BOD₅/m²·d. An aeration regime ranging from 5 h on/3 h off to 3 h on/5 h off was found to be adequate to optimize nitrogen removal, which ranged from 53% to 81%. Average removal rates of 3.4 ± 0.4 g total nitrogen (TN)/m²·d and 12.8 ± 3.7 g TN/m³·d were found in the aerated units, being 5.5 and 4.1 times higher than those of the non-aerated system. The tobermorite-enriched HF2 unit showed a distinct higher phosphate (60-67%) and total phosphorus (54%) removal.

[Home Treatment]

Home Treatment (HT) means acute psychiatric treatment in the patient's usual environment. Conceptually, HT is to be differentiated from other home-based services: It is limited with regard to duration and multiprofessional (e. g. psychiatrist plus psychiatric nursing staff plus social worker); the "24/7"-accessibility is frequently provided by the corresponding background hospital infrastructure. Target group are acutely mentally ill persons with an indication to inpatient treatment, who are willing to cooperate, and absence of endangerment to self and others. In contrast to the Scandinavian and many Anglophone countries where nationwide HT services are delivered, there are not many HT sites in Germany so far. Consequently, empirical data concerning HT in Germany is scarce. In summary, international studies show equivalent effects on psychopathological measures compared to inpatient treatment, reductions with regard to inpatient days, higher patient satisfaction and a trend towards cost-effectivity.

Promoting physical health in severe mental illness: patient and staff perspective

OBJECTIVE

To explore physical health problems and their causes in patients with severe mental illness, as well as possibilities for prevention and treatment from the patients' and staff's perspectives.

METHOD

We conducted six focus groups with patients and staff separately, from three out-patient clinics treating patients with schizophrenia or substance-use disorder comorbid to another psychiatric disorder. Focus groups were audio-recorded, transcribed verbatim and analysed using a template approach.

RESULTS

Paramount physical health problems are weight issues, cardiovascular diseases and poor physical shape. Main causes are lifestyle, the mental disorder and organisational issues. Patients and staff expressed similar opinions regarding physical health problems and their causes. Possibilities for prevention and treatment includes a case manager and binding communities with like-minded, as well as management support and implementation of physical health into daily psychiatric practice. Although patients and staff suggested different possibilities for prevention and treatment, they support one strategy: less fragmentation of the treatment system and cooperation between psychiatric and somatic healthcare.

CONCLUSION

To prevent and treat physical health problems in patients with severe mental illness, support in daily structure and lifestyle changes is needed. Management support is needed to change daily practice and implement routines regarding physical health.

Cost-effectiveness of intensive home treatment enhanced by inpatient treatment elements in child and adolescent psychiatry in Germany: A randomised trial

BACKGROUND

Admission rate to child and adolescent mental health inpatient units in Germany is high (54,467 admissions in 2013), resources for providing necessary beds are scarce. Alternative pathways to care are needed. Objective of this study was to assess the cost-effectiveness of inpatient treatment versus Hot-BITs-treatment (Hometreatment brings inpatient-treatment outside), a new supported discharge service offering an early discharge followed by 12 weeks of intensive support.

METHODS

Of 164 consecutively recruited children and adolescents, living within families and being in need of inpatient mental health care, 100 patients consented to participate and were randomised via a computer-list into intervention (n=54) and control groups (n=46). Follow-up data were available for 76 patients. Primary outcome was cost-effectiveness. Effectiveness was gathered by therapist-ratings on the Children's Global Assessment Scale (CGAS) at baseline (T1), treatment completion (T2) and an 8-month-follow-up (T3). Cost of service use (health care costs and non-health care costs) was calculated on an intention-to-treat basis at T2 and T3.

RESULTS

Significant treatment effects were observed for both groups between T1/T2 and T1/T3 (P<0.001). The Hot-BITs treatment, however, was associated with significantly lower costs at T2 (difference: -6900.47€, P=0.013) and T3 (difference: -8584.10€, P=0.007). Bootstrap cost-effectiveness ratio indicated that Hot-BITs was less costly and tended to be more effective at T2 and T3.

CONCLUSIONS

Hot-BITs may be a feasible cost-effective alternative to long inpatient stays in child and adolescent psychiatry. Further rigorous evaluations of the model are required. (

[Decentralized outpatient teams in community-based psychiatric care: comparison of two Bavarian rural catchment areas]

BACKGROUND

Psychiatric outpatient clinics (PIAs) are an indispensable care service for crisis intervention and multidisciplinary treatment of people suffering from severe and persistent mental disorders. The decentralization of outpatient clinics can be understood as a further step in the deinstitutionalization process.

METHODS

This cross-sectional study (n=1,663) compared the central outpatient clinic with the decentralized teams for the year 2010 by means of analyses of variance, χ(2)-tests and robust multivariate regression models. The longitudinal assessment (descriptively and by means of Prais-Winsten regression models for time series) was based on all hospitalizations for the two decentralized teams (n = 6,693) according to partial catchment areas for the time period 2002-2010 in order to examine trends after their installation in the year 2007.

RESULTS

Decentralized teams were found to be similar with respect to the care profile but cared for relatively more patients suffering from dementia, addictive and mood disorders but not for those suffering from schizophrenia and personality disorders. Decentralized teams showed less outpatient care costs as well as psychopharmacological expenses but a lower contact frequency than the central outpatient clinic. Total expenses for psychiatric care were not significantly different and assessed hospitalization variables (e.g. total number of annual admissions, cumulative length of inpatient-stay and annual hospitalizations per patient) changed slightly 3 years after installation of the decentralized teams. The number of admissions of people suffering from schizophrenia decreased whereas those for mood and stress disorders increased.

DISCUSSION

Decentralized outpatient teams seemed to reach patients in rural regions who previously were not reached by the central outpatient clinic. Economic figures indicate advantages for the installation of such teams because care expenses are not higher than for patients treated in centralized outpatient clinics and because hospitalization figures for the whole catchment area did not increase.

A systematic review of controlled interventions to reduce overweight and obesity in people with schizophrenia

OBJECTIVE

Overweight and obesity are generally found among patients with schizophrenia. This may lead to serious implications for health and wellbeing. The aim was to review controlled intervention studies on reducing overweight/obesity and/or reducing physical illness in patients with schizophrenia.

METHOD

A systematic literature search was carried out in the bibliographic databases PubMed (MEDLINE), Embase (Ovid), PsycInfo (Ovid) and Cinahl (Ebsco). We included all randomised and non-randomised clinically controlled studies that compared a non-pharmacological intervention, aimed at weight reduction and/or reducing physical illness, with standard care for patients with schizophrenia.

RESULTS

All 1713 references were evaluated for inclusion in the review. Twenty-three met the inclusion criteria and were categorised into four subgroups according to tested interventions: diet, exercise and cognitive behavioural therapy, or mixed combinations of the three. In this review, interventions showed efficacy in reducing weight and improving physical health parameters confirming that physical health improvement was possible in patients with schizophrenia.

CONCLUSION

The included studies indicate that the interventions reduced weight and improved physical health parameters in patients with schizophrenia.

Increased dust deposition in the Pacific Southern Ocean during glacial periods

Dust deposition in the Southern Ocean constitutes a critical modulator of past global climate variability, but how it has varied temporally and geographically is underdetermined. Here, we present data sets of glacial-interglacial dust-supply cycles from the largest Southern Ocean sector, the polar South Pacific, indicating three times higher dust deposition during glacial periods than during interglacials for the past million years. Although the most likely dust source for the South Pacific is Australia and New Zealand, the glacial-interglacial pattern and timing of lithogenic sediment deposition is similar to dust records from Antarctica and the South Atlantic dominated by Patagonian sources. These similarities imply large-scale common climate forcings, such as latitudinal shifts of the southern westerlies and regionally enhanced glaciogenic dust mobilization in New Zealand and Patagonia.

[Involuntary psychiatric hospital admissions: a comparison between five hospitals in three German federal states]

BACKGROUND

There is considerable variance in involuntary psychiatric hospital admission rates both in Europe and Germany. In a prospective comparison between five hospitals in three German federal states we assessed and analyzed involuntary psychiatric hospital admissions, including the patient's perspective.

MATERIAL AND METHOD

All involuntarily admitted patients were assessed by an independent researcher. Clinical data, patient and psychiatrist views were documented with different instruments including the McArthur admission experience survey.

RESULTS

In this study 104 out of 244 involuntarily admitted patients gave informed consent. We found considerable differences between study centres concerning involuntary admission quotas (3.2-25.8% of all hospital admissions) and involuntary admission rates (16.6-97.6 per year per 100,000 inhabitants). Hospitals in the state of Baden-Württemberg had the lowest involuntary admission rates while they were highest in Bavaria. In Baden-Württemberg involuntarily admitted patients were more likely to suffer from chronic schizophrenia, they were more severely ill and experienced the involuntary hospital admission as more strenuous. There were no differences between centres concerning frequency of dangerous behavior or self-harm.

CONCLUSION

We found a high variance across regions concerning the reasons for, frequencies and legal basis of involuntary hospital admissions. Regional differences of legal frameworks and service organization can explain this only to a limited amount. Transparency, legal certainty and reflection of stakeholder roles are a future necessity. Furthermore, there is a need for stringent compliance with legal regulations and coherent documentation.

[Maintenance of health and relief for caregivers of elderly with dementia by using "initial case management": experiences from the Lighthouse Project on Dementia, Ulm, ULTDEM-study]

BACKGROUND

When facing the well-known demographic development with an increasing number of people suffering from dementia, there is a need of programmes to support nursing relatives and care at home. Many support services have been established in the past few years but they are rarely used by the relatives and the patients. The purpose of the Lighthouse Project Ulm (ULTDEM Study) was to prove the effectiveness of a single advisory approach in order to provide support services after care level classification and to relieve the burden placed on relatives caring for family members suffering from dementia ("initial case management").

METHODS

The ULTDEM Study is a prospective, open, randomized, controlled, interventional study with different parallel outcome measures (burden of caring, quality of life and mood). After the randomization, the interventional group was given comprehensive, individual advice about available treatment possibilities for dementia patients. Control group participants received standard treatment. Inclusion criteria were application of a care level (0 or 1) as well as dementia diagnosis. All participants (patients/relatives) underwent an initial and a 6 month comprehensive assessment.

RESULTS

Our results show that a single advisory approach does not lead to a significant difference in outcome measures in interventional and control groups. Those tendencies described have to be interpreted as clinically not relevant. Although utilization of support services increases, it remains similar in both study groups. A confirmatory interpretation has not been possible due to a lack of adjustment to the findings regarding multiple testing and an insufficient degree of recruitment. Possible causes will be discussed such as premature intervention during the course of the disease, a lack of intervention blinding, recruitment bias and lack of an influence on adherence with regard to the use of support services.

IMPLICATIONS

The study demonstrates that there is a substantial information deficit for persons affected by dementia and their relatives. Innovative ways still have to be developed to ensure that this information actually reaches the target audience.

Effects of polypharmacy on outcome in patients with schizophrenia in routine psychiatric treatment

OBJECTIVE

Evaluating the effects of different types of psychotropic polypharmacy on clinical outcomes and quality of life (QOL) in 374 patients with schizophrenia and schizoaffective disorder in routine care.

METHOD

Psychotropic regimen, clinical outcomes, and QOL were assessed before discharge and after 6, 12, 18, and 24 months. Data were analyzed by mixed-effects regression models for longitudinal data controlling for selection bias by means of propensity scores.

RESULTS

At baseline 22% of participants received antipsychotic monotherapy (APM) (quetiapine, olanzapine, or risperidone), 20% more than one antipsychotic drug, 16% received antipsychotics combined with antidepressants, 16% antipsychotics plus benzodiazepines, 11.5% had antipsychotics and mood stabilizers, and 16% psychotropic drugs from three or more subclasses. Patients receiving APM had better clinical characteristics and QOL at baseline. Patients receiving i) antipsychotics plus benzodiazepines or ii) antipsychotics plus drugs from at least two additional psychotropic drug categories improved less than patients with APM.

CONCLUSION

Combinations of antipsychotics with other psychotropic drugs seem to be effective in special indications. Nevertheless, combinations with benzodiazepines and with compounds from multiple drug classes should be critically reviewed. It is unclear whether poorer outcomes in patients with such treatment are its result or its cause.

Psychotropic drug treatment, clinical characteristics and cognitive processing speed in patients with schizophrenia: results from the ELAN study

INTRODUCTION

Psychotropic drug combinations (PDC) are common in the treatment of patients with schizophrenia but there is little research regarding the effects of PDC on cognition.

OBJECTIVE

The aim of this study was to analyse the effects of antipsychotic monotherapy and various types of PDC on cognitive processing speed (CPS).

METHODS

ELAN is a 24-month multi-site prospective observational controlled trial following up 374 patients with schizophrenia under routine treatment conditions following discharge from inpatient treatment. The propensity score method, multinomial logistic regression analyses and mixed effects regression models were used.

RESULTS

CPS correlated significantly with PANSS and GAF scores and improved over time in the monotherapy group. Negative effects of some PDC (antipsychotics + tranquilizers/antipsychotics+at least 2 other psychopharmacological subclasses, sedative/anticholinergic drugs/high adjusted antipsychotic dose) lost significance after controlling for clinical characteristics.

DISCUSSION

Indications for PDC should be examined with care although, in the present study, effects on cognition were small.

[German practice of involuntary commitment at both federal and state level after introduction of the Guardianship law (1992-2009)]

BACKGROUND

Given the steady rise of psychiatric coercive measures in Germany, the question arises whether this development is significantly influenced by the corresponding legal basis or through epidemiological, socio-economic or socio-structural factors.

METHODS

Based on full surveys of the Federal Ministry of Justice we examined the development and associations of 10 indicators of coercive psychiatric measures over a period of 18 years. Time trends of all indicators have been descriptively analysed. Statistical associations between time trends and between involuntary and admissions economic indicators were analysed by regression models.

RESULTS

All annual involuntary commitment rates have increased, judicial ordered physical restraint measures particularly strongly (848%). The rate of judicial rejections of applied involuntary measures showed the lowest increase. On the other hand, quotas of involuntary admissions remained stable. In former East Germany, the involuntary admission rates are only a third of those in the former West Germany. Results of regression analyses indicate an excess increase of physical coercive measures in psychiatric hospitals in relation to the increase of psychiatric admissions. In former East Germany the rate of involuntary admissions at the federal state level is negatively correlated with the average gross income.

DISCUSSION

The continuous increase of coercive psychiatric measures in consequence to the change in the Guardianship law suggests that this change has influenced the practice. The differences at federal and state levels, and the sharper rise in the former East Germany by lower rates in comparison to the former West Germany need an explanation, as well as the fact that the rate of involuntary admissions is associated at least in the former East Germany with economic conditions.

A Multi-Centre Pragmatic Trial of Antipsychotic Drug Treatment

The ELAN study is a prospective multi centre observational trial on the effectiveness and safety of long-term antipsychotic treatment of people with schizophrenia or schizoaffective disorders with quetiapine in comparison to olanzapine and risperidone under real world treatment conditions.

374 adult persons with schizophrenia or schizoaffective disorder prescribed antipsychotic maintenance therapy with quetiapine, olanzapine or risperidone were included at discharge from inpatient treatment. Psychotropic regimen, psychopathological symptoms, general and cognitive functioning, negative side-effects and quality of life were assessed before discharge and at 6, 12, 18 and 24 month follow-up assessments. Intention-to-treat analyses and crossover analyses were conducted by mixed-effects regression models including random linear time effects and time x treatment effects, controlling for baseline differences and additional psychotropic medication and using propensity scores to control for selection bias.

As indicated by significant linear time effects the patients improved with regard to psychopathological symptoms, general functioning, subjective quality of life and cognitive processing speed. No change of extrapyramidal motor side-effects, body mass index or waist circumference was obtained. The lack of any significant time x treatment interaction effects indicated no differences in the safety or effectiveness between the three antipsychotics. Nevertheless, the average hospital admission rate of patients receiving olanzapine was lower in comparison to patients receiving quetiapine or risperidone.

The helps toolkit - a tool to promote the physical health of residents in psychiatric facilities across Europe

Introduction

People with a mental disorder are at increased risk for physical illness and therefore their risk of premature death is raised. An unhealthy lifestyle, living conditions, medication side-effects and a lack of physical health monitoring are regarded as the main causes of high somatic morbidity. But up to now only little research has addressed the physical co-morbidity in mentally ill. At present, there are no specific policies to improve the health status of residents in mental health care facilities.

Against this background a multi-disciplinary network of experts from 15 European countries was set up. Working together with researchers, stakeholders, professionals, networks, practitioners, and relevant organizations, the HELPS network developed a “physical health promotion toolkit” for routine application in a wide range of mental health care facilities across Europe. The HELPS toolkit intends to empower patients and staff to identify the most relevant risk factors in their specific context and subsequently select the most appropriate action out of a range of defined health promoting interventions. In doing so, the toolkit takes into account the heterogeneity of mental disorders, the high number of somatic problems, aspects of lifestyle, environment, medical care system, personal goals of patients and their motivation for health behavior.

Results / conclusions

The poster presents the HELPS toolkit. It illustrates the individual components of the tool and the processes of its implementation and evaluation. First results of the pilot study concerning the feasibility of the toolkit will be presented and discussed.

[Methods of health economic evaluation for health services research]

On August 30, 2010, the German Network for Health Services Research [Deutsches Netzwerk Versorgungsforschung e. V. (DNVF e. V.)] approved the Memorandum III "Methods for Health Services Research", supported by the member societies mentioned as authors and published in this Journal [Gesundheitswesen 2010; 72: 739-748]. The present paper focuses on methodological issues of economic evaluation of health care technologies. It complements the Memorandum III "Methods for Health Services Research", part 2. First, general methodological principles of the economic evaluations of health care technologies are outlined. In order to adequately reflect costs and outcomes of health care interventions in the routine health care, data from different sources are required (e. g., comparative efficacy or effectiveness studies, registers, administrative data, etc.). Therefore, various data sources, which might be used for economic evaluations, are presented, and their strengths and limitations are stated. Finally, the need for methodological advancement with regard to data collection and analysis and issues pertaining to communication and dissemination of results of health economic evaluations are discussed.

Limits of meta-analysis: methylphenidate in the treatment of adult attention-deficit hyperactivity disorder

Guidelines for the treatment of attention-deficit hyperactivity disorder (ADHD) in adults advocate methylphenidate as first-line treatment. The aim of this study was to review the effectiveness of methylphenidate treatment of adult ADHD and to examine the influence of methods on meta-analytic results. Electronic databases were searched to identify clinical trials comparing methylphenidate with placebo in the treatment of adult ADHD. Studies were summarised with meta-analytic methods. Subgroup analyses were conducted with respect to parallel group versus cross-over trials and self versus observer ratings. The relationship between dosage and effect size was explored by weighted regression analysis. The results were tested for publication bias, and several sensitivity analyses were performed. Findings and methods were compared with a previous meta-analysis. Eighteen studies met the inclusion criteria of which 16 were included in the meta-analysis. The overall effect size (d = 0.42) was significantly different from zero, but was only half the size expected on the basis of a previous meta-analysis. No significant differences could be observed in the subgroup analyses. The regression analysis showed no significant influence of mean daily dose on effect size. These results contradict findings of a previous meta-analysis and challenge guideline recommendations. Methodological issues in meta-analyses are discussed.

Family Needs, Children and Parenthood in People with Mental Illness

Objective:

Given that parental mental diseases affect the whole family system, a family centered support and help system seems appropriate for families with a mentally ill mother/father. However, the majority of mental health services do not integrate interventions for the family system into psychiatric treatment programs.

Aims:

To introduce a counselling and support service for families with a mentally ill parent (FIPS) that has been established at a psychiatric hospital serving a large catchments area. Preliminary results of a qualitative study that focused on the clients’ family background as well as on their reasons for utilising the service and service satisfaction will be presented.

Methods:

Factors that impact the family system are considered and brought to a concept for counselling and support service for families with a mentally ill parent. Problem-focused interviews with 14 clients (mentally ill parents and relatives) of the counselling service for families were subjected to content analysis.

Results:

Most clients came to the counselling centre because of worries that the parent's mental illness might negatively affect children's well-being. Mentally ill mothers described their daily lives as utterly burdensome and also reported strong feelings of guilt towards their children. The concept of FIPS includes psychoeducation, social therapy, case management and family therapy. Clients assessed the counselling service as helpful and reported some significant changes.

Effects of symptom reduction and psychotropic medication on cognitive impairment in depression

BACKGROUND

Depression is related to cognitive performance. This follow-up study examines the influence of depression symptoms and psychopharmacological treatment on change in the cognitive performance of patients with depressive episodes over a 2-year period.

SAMPLING AND METHODS

Sixty-two in- and outpatients with depression of varying severity (ICD-10: F31-F33) were examined in an open prospective naturalistic observational study with 3 points of measurement and tested by use of 3 computerized cognitive performance tests [Visual Attentiveness Test (VAT), Continuous Attention Test (CAT), Word Recognition Test (WRT)], while the psychotropic medication was classified by subclass and dosage. Statistical analysis was performed by random-effects regression models.

RESULTS

The raw values of VAT speed, CAT speed and WRT quality improved over time. However, the positive time trend disappeared after the patients' clinical and personal characteristics were controlled for. The processing speed of the VAT was found to be negatively influenced by depressive symptoms. That of the CAT developed favorably with increasing level of education. The performance qualities of the VAT, WRT and CAT were positively related to the participants' educational level. The patients who received antipsychotic treatment performed worse on WRT quality than those who were not treated with antipsychotics.

CONCLUSIONS

The cognitive performance was relatively stable during the treatment process and not affected by clinical characteristics or type of medication. Cognitive deficits in patients with depression could be a trait rather than a state marker.

Health behavior in psychiatric in-patients compared with a German general population sample

OBJECTIVE

To compare the health relevant behavior of psychiatric patients and the general population.

METHOD

Health behavior of 363 psychiatric in-patients with ICD-10 diagnoses of schizophrenia, bipolar disorders, major depressive disorders and neurotic, and somatoform disorders was compared with health behavior of a representative sample of 7200 persons from German general population.

RESULTS

Increased prevalence rates for smoking and illicit drug use were found for all diagnostic groups. Risk alcohol consumption was increased in patients with schizophrenia and depression. Smokers with schizophrenia had an excess cigarette consumption compared with general population. The number of unhealthy food habits was increased in all diagnostic groups, and the body mass index was found to be increased for patients with schizophrenia. Patients with depression were more physically active than general population.

CONCLUSION

Poor health behavior is widespread in patients with all major psychiatric diagnoses. Interventions to reduce risk behavior and strengthen health preventive lifestyles are necessary.

Psychiatric services for people with severe mental illness across western Europe: what can be generalized from current knowledge about differences in provision, costs and outcomes of mental health care?

OBJECTIVE

To report recent findings regarding differences in the provision, cost and outcomes of mental health care in Europe, and to examine to what extent these studies can provide a basis for improvement of mental health services and use of findings across countries.

METHOD

Findings from a number of studies describing mental health care in different European countries and comparing provision of care across countries are reported.

RESULTS

The development of systems of mental health care in western Europe is characterized by a common trend towards deinstitutionalization, less in-patient treatment and improvement of community services. Variability between national mental healthcare systems is still substantial. At the individual patient level the variability of psychiatric service systems results in different patterns of service use and service costs. However, these differences are not reflected in outcome differences in a coherent way.

CONCLUSION

It is conceivable that the principal targets of mental healthcare reform can be achieved along several pathways taking into account economic, political and sociocultural variation between countries. Differences between mental healthcare systems appear to affect service provision and costs. However, the impact of such differences on patient outcomes may be less marked. The empirical evidence is limited and further studies are required.

„Home treatment“ für psychische Erkrankungen

A number of projects have used home treatment (HT) for severely mentally ill people in recent years. This paper intends to define HT and show the main differences between it and other forms of psychiatric community service, present the existing evidence for HT, and discuss eligibility criteria. Studies about HT's efficacy in treating severely mentally ill adults were identified by electronic (MEDLINE, PsycLIT) and manual search. Six studies met these inclusion criteria. Compared to inpatient treatment, HT was equally or more efficacious in respect to reduction of symptom distress, social (re-)integration, and patient and carer satisfaction. Furthermore, direct costs for HT were often lower than for inpatient care. However, the number of relevant studies is limited and knowledge on the long-term effects of HT is sparse.

Quality of life in persons with schizophrenia in out-patient treatment with first- or second-generation antipsychotics

OBJECTIVE

Effects of first in comparison with second-generation antipsychotics on the subjective quality of life (QoL) of patients with schizophrenia under routine treatment conditions were examined.

METHOD

In a prospective naturalistic trial the QoL, social, clinical, and treatment-related characteristics and type of antipsychotic medication of 307 patients with schizophrenia (ICD-10 F 20) were assessed five times with 6-month intervals over 2.5 years. Longitudinal and cross-sectional effects of antipsychotic medication were assessed by hierarchical regression models. Selection bias was controlled by propensity scores.

RESULTS

While positive effects of first-generation antipsychotics on subjective QoL in comparison with no antipsychotic treatment were found, second-generation antipsychotics caused no better QoL than first-generation antipsychotics.

CONCLUSION

The hypothesis that second-generation in comparison with first-generation antipsychotics have a better effect on the improvement of subjective QoL of people with schizophrenia in routine out-patient treatment was not supported.

Methodische Grundlagen naturalistischer Beobachtungsstudien zur ökonomischen Evaluation der Neuroleptikabehandlung bei schizophrenen Erkrankungen

Methodological problems of prospective natural trials are discussed. The application of adequate methods is demonstrated by analysing the effects of antipsychotic medical treatment on the probability and the costs of inpatient episodes of 307 patients with schizophrenia for 2.5 years. Selection bias is controlled by the propensity score method. Effects of medical treatment on the incidence of inpatient episodes are analysed by means of a random-effect logit model. Effects of medical treatment on the costs of inpatient episodes are analysed by means of a random-effect Tobit model. Results of the study show that antipsychotic medical treatment reduces the probability and the costs of inpatient treatment irrespective of the type of neuroleptic drugs. The hypothesis of a higher effectivity of atypical neuroleptics in comparison to conventional antipsychotics regarding the reduction of the incidence and the costs of inpatient treatment was not supported. Beyond the effects of medical treatment the study results indicate that improving social support and competence for coping with life events as well as providing community mental health services may reduce the risk and the costs of inpatient episodes.

Natural mercury enrichment in a minerogenic fen—evaluation of sources and processes

Mercury (Hg) records in natural archives such as peat bogs are often used to evaluate anthropogenic or climatic influences on atmospheric Hg deposition. In this context, there is an ongoing discussion about natural sources or processes of Hg enrichment in natural archives. In the present study we estimated Hg fluxes from rock weathering, direct atmospheric deposition and from indirect atmospheric deposition in the catchment of a pristine minerogenic fen (GC2) located in the Magellanic Moorlands, southernmost Chile. The Hg record in the bog covers 11 174 cal. (14)C years and shows Hg concentrations of up to 570 [micro sign]g kg(-1) with an average of 268 [micro sign]g kg(-1). Hg was found to be enriched in the peat by a factor of 81 if compared to the mean Hg concentrations in the rocks of the catchment (3.2 [micro sign]g kg(-1)). Hg and also Pb, Fe, and As were found to be enriched predominately in goethite layers indicating high retention of these elements in the bog by iron oxyhydrates. It could also be demonstrated that the high peat decomposition rates in minerogenic bogs can increase the Hg concentrations in the minerogenic peat by a factor of approximately 2 at the same atmospheric Hg deposition rate if compared to ombrotrophic sites. This study has shown that Hg in minerogenic peat can be naturally enriched especially through the retention by autochthonous formed goethite and can be a solely internal process which does not require increased external Hg fluxes.

[The impact of the study design and the sampling procedure on the assessment of mental health services]

In this paper the impact of the study design and the sampling procedure on the assessment of the costs of schizophrenia treatment will be analyzed. The study sample consists of 307 patients with the diagnosis of schizophrenia (ICD 10F20) with the age between 18 and 65 years. Study participants were recruited consecutively in inpatient and outpatient treatment settings and in accommodation facilities according to the proportions of patients treated in these settings in Leipzig which have been assessed before. Treatment costs have been assessed by means of the German version of the Client Sociodemographic and Service Receipt Inventory at five follow-ups at six-months intervals. For the whole study period significant differences of the mean service costs due to the recruitment setting have been found. The mean yearly costs amounted to 44.669 DM for participants recruited in sheltered accommodation, 27.975 DM for participants in inpatient treatment and 5691 DM for patients in outpatient facilities. A random-effect regression model confirmed significant effects of the recruitment setting over all five follow-ups. Additionally, the variance of costs over time indicates that cost assessment by means of cross sectional data involves the danger of errors due to random dispersion.
