Lessons from community mental health to drive implementation in health care systems for people with long-term conditions.

This paper aims to identify which lessons learned from the evidence and the experiences accruing from the transformation in mental health services in recent decades may have relevance for the future development of healthcare for people with long-term physical conditions. First, nine principles are discussed which we first identified to guide mental health service organisation, and all of which can be potentially applied to long term care as well (autonomy, continuity, effectiveness, accessibility, comprehensiveness, equity, accountability, co-ordination, and efficiency). Second, we have outlined innovative operational aspects of service user participation, many of which were first initiated and consolidated in the mental health field, and some of which are now also being implemented in long term care (including case management, and crisis plans). We conclude that long term conditions, whether mental or physical, deserve a long-term commitment from the relevant health services, and indeed where continuity and co-ordination are properly funded implemented, this can ensure that the symptomatic course is more stable, quality of life is enhanced, and the clinical outcomes are more favourable. Innovations such as self-management for long-term conditions (intended to promote autonomy and empowerment) need to be subjected to the same level of rigorous scientific scrutiny as any other treatment or service interventions.

Cost-effectiveness of adherence therapy versus health education for people with schizophrenia: randomised controlled trial in four European countries.

BACKGROUND: Non-adherence to anti-psychotics is common, expensive and affects recovery. We therefore examine the cost-effectiveness of adherence therapy for people with schizophrenia by multi-centre randomised trial in Amsterdam, London, Leipzig and Verona. METHODS: Participants received 8 sessions of adherence therapy or health education. We measured lost productivity and use of health/social care, criminal justice system and informal care at baseline and one year to estimate and compare mean total costs from health/social care and societal perspectives. Outcomes were the Short Form 36 (SF-36) mental component score (MCS) and quality-adjusted life years (QALYs) gained (SF-36 and EuroQoL 5 dimension (EQ5D)). Cost-effectiveness was examined for all cost and outcome combinations using cost-effectiveness acceptability curves (CEACs). RESULTS: 409 participants were recruited. There were no cost or outcome differences between adherence therapy and health education. The probability of adherence therapy being cost-effective compared to health education was between 0.3 and 0.6 for the six cost-outcome combinations at the willingness to pay thresholds we examined. CONCLUSIONS: Adherence therapy appears equivalent to health education. It is unclear whether it would have performed differently against a treatment as usual control, whether such an intervention can impact on quality of life in the short-term, or whether it is likely to be cost-effective in some sites but not others. TRIAL REGISTRATION: Trial registration: Current Controlled Trials ISRCTN01816159.

The balanced care model: the case for both hospital- and community-based mental healthcare.

The balanced care model proposes that a comprehensive mental health system needs to include both community- and hospital-based care. The model is based on a structured review of scientific evidence, and is also informed by the experience of experts active in mental health system change in many countries worldwide.

Prediction of community mental health service utilization by individual and ecological level socio-economic factors.

Individuals with a more deprived socioeconomic status (SES) are more likely to have higher rates of psychiatric morbidity and use of psychiatric services. Such service use is also influenced by socioeconomic factors at the ecological level. The aim of this article is to investigate the influence of these variables on service utilization. All patients in contact with three Italian community psychiatric services (CPS) were included. Community and hospital contacts over 6 months were investigated. Socio-economic characteristics were described using a SES Index and two new Resources Accessibility Indexes. Low SES was found to be associated with more community service contacts. When other individual and ecological variables were controlled for, SES was negatively associated only with the number of home visits, which was about half the rate in deprived areas. An association between service utilization and the resources of the catchment area was also detected. The economic crisis in Europe is increasing inequality of access, so paying attention to SES characteristics at both the individual and the ecological levels is likely to become increasingly important in understanding patterns of psychiatric service utilization and planning care accordingly.

Is neuregulin 1 involved in determining cerebral volumes in schizophrenia? Preliminary results showing a decrease in superior temporal gyrus volume.

BACKGROUND/AIMS: Reduced left superior temporal gyrus (STG) volume is one of the most replicated imaging findings in schizophrenia. However, it remains unclear whether genes play any role in our understanding of such structural alteration. It has been proposed that Neuregulin 1 (NRG1) might be a promising gene involved in schizophrenia, because of its role in neurodevelopment and neuroplasticity. In this study, the association between NRG1 and STG anatomy in patients with schizophrenia was explored for the first time. METHODS: We investigated a 1-year treated prevalence cohort of patients with schizophrenia in contact with the South Verona Community-Based Mental Health Service. A blood sample was collected for DNA extraction and brain structure was assessed with an MRI scan. A total of 27 subjects with schizophrenia underwent both assessments and were included in the study. RESULTS: We investigated the association between the polymorphism SNP8NRG222662 (rs4623364) of NRG1 and volume of the STG. We found that patients homozygous for the C allele had reduced left STG gray and white matter volumes in comparison to those homozygous for the G allele (p < 0.01 and p < 0.001, respectively). CONCLUSIONS: This exploratory study suggests that NRG1 may be involved in determining STG size in schizophrenia, and may play a role in the neurogenetic basis of the language disturbances seen in this disorder. However, due to our small sample size, the results should be regarded as preliminary and replicated in a larger sample.

How are caseload and service utilisation of psychiatric services influenced by distance? A geographical approach to the study of community-based mental health services.

INTRODUCTION: The aim of this study was to assess how the caseload and the utilisation of community-based mental health services is influenced by distance and to socioeconomic characteristics. METHODS: Spatial and statistical analyses were conducted with a sample of 12,347 patients, with ICD-10 psychiatric diagnosis, who had at least one contact with psychiatric services in Verona, Italy, between 2000 and 2006. Three types of mental health facility were considered: acute inpatient wards, outpatient clinics, and community mental health centres (CMHC). To measure distance and accessibility, the locations of static mental health facilities and patients' homes were geocoded. Data were organised in a spatial database, which included census blocks, catchment areas locations, road network graphs, patients' and facilities' locations. In order to calculate travel distances, patients' and facilities' locations were connected to the road network. Accessibility was modelled by using the Network Analyst Service Area Function and 13 Service Areas were created around all facility locations, by measuring distances along the street network. For the epidemiological analyses, patients and census block centroids were linked to the service areas by using spatial join techniques. Epidemiological and utilisation analyses were performed for each type of setting. RESULTS: The facilities were not equally located in the catchment areas. Of particular significance, rural areas appear to be poorly served by mental health services. The distance decay effect exists, with different trends for the three types of facility. The caseload (number of patients using services) decreased with increasing distance; at a distance of 10 km, there was a decrease of 80, 60 and 85%, respectively, for CMHCs, inpatients wards and outpatients clinics. From the Poisson regression models, distance was significantly correlated (p value < 0.0001) with service use. Also univariate analyses showed a statistically significant association between distance and caseload for each type of setting (p value < 0.05), with a decrease in service use for each service area increase in distance (1.5% for acute inpatient wards, 2.0% for CMHC, and 2.1% outpatient clinics). By adding other predictors in the Poisson regression models, these percentages increased. CONCLUSIONS: Further studies are needed to evaluate the influence of other factors, such as environmental variables, that may influence the use of mental health services.

Comparison of patient and clinician perspectives in the assessment of antipsychotic medication adherence.

BACKGROUND: Factors influencing patient and clinician perspectives in the assessment of medication adherence have never been compared. METHOD: This study used baseline and 12-month follow-up data from the QUATRO study, an international multicentre study. At baseline, information on patient sociodemographic characteristics, treatment factors, psychopathology, functioning and experience of antipsychotic side effects was gathered. After 12 months of follow-up, psychopathology, functioning and patient experience of antipsychotic side effects were measured once more, and a patient and clinician rating of adherence was obtained by means of the Medication Adherence Rating Scale (MARS) and the Compliance Rating Scale (CRS). RESULTS: During the recruitment period, 409 subjects with a diagnosis of schizophrenia were recruited. Patients were more often men and single. Mean age was 41.5 years. At the time of the assessment, more than 40% were unemployed and on average had been on antipsychotic treatment for more than 10 years. Nearly 70% were receiving second-generation antipsychotics, and 50% received adherence therapy during the 12 months after enrollment. The relationship between the MARS and the CRS scores showed only a small overlap (correlation coefficient = 0.26). In the multivariate model, the only factor significantly associated with both patient and clinician ratings of adherence was psychopathology. Unemployment and poor subjective tolerability of antipsychotics were significantly associated with low levels of patient ratings of adherence. Conversely, length of treatments and use of newer antipsychotics were significantly associated with better clinician ratings of adherence. CONCLUSION: Patient and clinician ratings of adherence do not measure the same dimension. Factors that may positively affect adherence in terms of compliance with prescribed medication regimens may not affect patients' views on adherence, and this should be taken into consideration when planning and negotiating treatment modalities with each individual patient suffering from schizophrenia.

Understanding antipsychotic non-classical prescriptions: a quantitative and qualitative approach.

AIMS: To date only a few studies investigated the clinical reasons supporting and explaining non-classical antipsychotic prescriptions. The present study was carried out to develop concepts which help understand this phenomenon in a natural setting, giving emphasis to views of clinicians according to quali - quantitative research methodologies. SUBJECTS: From the South-Verona Psychiatric Case Register all antipsychotic prescriptions issued during 2005 were extracted. Concurrent prescribing of two or more antipsychotics, prescribing antipsychotic drugs outside the licensed indications, and outside the licensed ranges of doses reported in the Italian National Formulary, were considered non-classical prescriptions. Reasons for non-classical prescriptions were collected by means of brainstorming sessions with clinicians. Non-classical prescriptions and the corresponding reasons were grouped according to whether they were "clinically sound" or "clinically not sound". RESULTS: During 2005 a total of 259 patients received 376 non-classical prescriptions. The most frequently reported reasons for non-classical prescribing were that prescriptions were inherited from another clinician with or without benefit, and that prescriptions were motivated by the need of reducing psychotic symptoms. More than 60% of these non-classical prescriptions were categorised as "clinically sound". Clinically not sound prescriptions were related with negative clinicians' views and opinions about the patient/clinician relationship. CONCLUSION: Clinically not sound prescriptions appeared just a reflection of a problematic doctor/patient relationship, where no individual treatment plan existed and psychiatric visits had the only goal of monitoring ongoing prescriptions.

Assessment of medication adherence in patients with schizophrenia: the Achilles heel of adherence research.

Measuring medication adherence in patients with schizophrenia is difficult and lacks a gold standard. Consequently, a great number of different methods and instruments have been proposed. Although it has been assumed that they all measure medication adherence, this study demonstrates that instruments differ significantly. Using data from an international multisite study (N = 329), we found that 3 questionnaires, designed to measure medication adherence and typical for instruments used in studies in patients with schizophrenia, do not agree in labeling patients as nonadherent. Further, they seem not to measure the same trait, are related to different established risk factors of nonadherence, and are only weakly related to these established risk factors of nonadherence. If these results are representative of the validity of other measures used in adherence research, this may have serious consequences for the interpretation of, and explanations for discrepancies found in the literature. Researchers should be aware of this problem and continue to combine objective and subjective methods in the hope of increasing the reliability and validity of measures of adherence.

[Heterogeneity of the Departments of Mental Health in the Veneto Region ten years after the National Plan 1994-96 for Mental Health. Which implication for clinical practice? Findings from the PICOS Project]. / Eterogeneità dei DSM veneti a dieci anni dal Progetto Obiettivo "Tutela Salute Mentale 1994-96". Quali implicazioni per la pratica clinica? Indagine sui servizi partecipanti al Progetto PICOS-Veneto.

AIMS: This study aims to present data on structural and human resources of public mental health services located in the Veneto Region, Italy, and to discuss them in the light of implementation of the first National Target Plan for Mental Health ("Progetto Obiettivo 1994-1996") ten years after its launch. METHODS: The study was conducted in the context of the PICOS (Psychosis Incident Cohort Outcome Study) Project, a large first-presentation multisite study on patients with psychotic disorders attending community mental heath services in the Veneto Region. Human and structural resources were surveyed in 26 study sites using a structured interview administered by the PICOS local referents. RESULTS: CMHCs and Day Centres were homogeneously distributed across the Region and their overall rates per resident population met the national standards; a wide variability in the distribution of Day Hospitals was found, with the overall rate per resident population very far from meeting the national standard; the overall rate for Residential Facilities beds was higher than the recommended national standard, showing however an high variability across sites. The overall rate of mental health professionals per resident population was only slightly below the national standard: this was mainly achieved thanks to non-profit organizations which supplement the public system with unspecialised professionals; however, a wide variability in the local rates per resident population was found, with the 50% of the sites showing rates far lower the national standard. Specific lack of trained professionals involved in the provision of psychosocial interventions was found in most sites. CONCLUSIONS: A marked variability in human and structural resources across community mental health services in the Veneto Region was found. Possible reasons for this heterogeneity were analysed and implications for mental health care provision were further discussed.

Fair assessment of the merits of psychiatric research.

BACKGROUND: Use of bibliometric assessments of research quality is growing worldwide. So far, a narrow range of metrics have been applied across the whole of biomedical research. Without specific sets of metrics, appropriate to each sub-field of research, biased assessments of research excellence are possible. AIMS: To discuss the measures used to evaluate the merits of psychiatric biomedical research, and to propose a new approach using a multidimensional selection of metrics appropriate to each particular field of medical research. METHOD: Three steps: (a) a definition of scientific 'domains', (b) translating these into 'filters' to identify publications from bibliometric databases, leading to (c) the creation of standardised measures of merit. RESULTS: We propose using: (a) established metrics such as impact factors and citation indices, (b) new derived measures such as the 'worldscale' score, and (c) new indicators based on journal peer esteem, impact on clinical practice, medical education and health policy. CONCLUSIONS: No single index or metric can be used as a fair rating to compare nations, universities, research groups, or individual investigators across biomedical science. Rather, we propose using a multidimensional profile composed of a carefully selected array of such metrics.

Predicting costs of mental health care: a critical literature review.

BACKGROUND: Cost evaluation research in the mental health field is being increasingly recognized as a way to achieve a more effective deployment of scarce resources. However, there is a paucity of studies that seek to identify predictors of psychiatric service utilization and costs. This paper aims to critically review the published research in the field of psychiatric service utilization and costs, and discusses current methodological developments in this field. METHOD: Sixteen studies were identified and are critically reviewed. RESULTS: No single variable alone can explain variations in costs between patients; instead, a range of different clinical and non-clinical variables provides a greater explanation of cost variations. Having a history of previous psychiatric service use is the most consistent predictor of higher psychiatric costs. Only one study considers indirect costs incurred by users, their families and friends and society as a whole, with the remaining 15 studies focusing on direct mental health care costs. There is a lack of studies that consider the future psychiatric service utilization and costs of care of children and older people. The cross-validation of predictive models is not yet routine, with only four of the studies including a cross-validation procedure. CONCLUSIONS: The predictive approach in mental health cost evaluation has relevance for both mental health policy and practice. However, there is a paucity of studies that focus on children, older people and indirect costs. Furthermore, there remain a number of methodological challenges to address.

Assessment of cerebral blood volume in schizophrenia: A magnetic resonance imaging study.

Brain atrophy has consistently been observed in schizophrenia, representing a 'gross' evidence of anatomical abnormalities. Reduced cerebral blood volume (CBV) may accompany brain size decrement in schizophrenia, as suggested by prior small SPECT studies. In this study, we non-invasively investigated the hemisphere CBV in a large sample of patients suffering from schizophrenia with perfusion-weighted imaging (PWI). PWI images were obtained, following intravenous injection of paramagnetic contrast agent (Gadolinium-DTPA), for 54 DSM-IV patients with schizophrenia (mean age+/-SD=39.19+/-12.20 years; 34 males, 20 females) and 24 normal controls (mean age+/-SD=44.63+/-10.43 years; 9 males, 15 females) with a 1.5T Siemens magnet using an echo-planar sequence (TR=2160 ms, TE=47 ms, slice thickness=5mm). The contrast of enhancement (CE), a semi-quantitative parameter inversely estimating the CBV, were calculated pixel by pixel as the ratio of the maximum signal intensity drop during the passage of contrast agent (Sm) by the baseline pre-bolus signal intensity (So) (CE=Sm/Sox100) for right and left hemisphere on two axial images. Specifically, higher CE values correspond to lower CBV and viceversa Compared to normal controls, patients with schizophrenia had significantly higher bilateral hemisphere CE values (p=0.02) and inverse CE laterality index (p=0.02). This study showed abnormally reduced and inverse hemisphere CBV in a large population of patients with schizophrenia. Hypothetically, chronic low CBV may sustain neural hypoactivation and concomitant increase of free radicals, ultimately resulting in neuronal loss and cognitive impairments. Thus, altered intracranial hemodynamics may accompany brain atrophy and cognitive deficits, being a crucial factor in the pathophysiology of schizophrenia.

[Proposal for a new funding system for mental health departments. Results from an evaluative multicentre Italian study (I-psycost)]. / Proposta per un nuovo sistema di finanziamento dei dipartimenti di salute mentale. Risultati di uno studio valutativo multicentrico nazionale (I-psycost study).

AIMS: To obtain a new, well-balanced mental health funding system, through the creation of (i) a list of psychiatric interventions provided by Italian Community-based Psychiatric Services (CPS), and associated costs; (ii) a new prospective funding system for patients with a high use of resources, based on packages of care. METHODS: Five Italian Community-based Psychiatric Services collected data from 1250 patients during October 2002. Socio-demographical and clinical characteristics and GAF scores were collected at baseline. All psychiatric contacts during the following six months were registered and categorised into 24 service contact types. Using elasticity equation and contact characteristics, we estimate the costs of care. Cluster analysis techniques identified packages of care. Logistic regression defined predictive variables of high use patients. Multinomial Logistic Model assigned each patient to a package of care. RESULTS: The sample's socio-demographic characteristics are similar, but variations exist between the different CPS. Patients were then divided into two groups, and the group with the highest use of resources was divided into three smaller groups, based on number and type of services provided. CONCLUSIONS: Our findings show how is possible to develop a cost predictive model to assign patients with a high use of resources to a group that can provide the right level of care. For these patients it might be possible to apply a prospective per-capita funding system based on packages of care.

Does additional care provided by a consumer self-help group improve psychiatric outcome? A study in an Italian community-based psychiatric service.

This study compares the two-year clinical and social outcome, the use of services and the direct costs of patients of the South-Verona Community Psychiatric Service who were members of a self-help group, with those who were not. Use of services and costs in the two years before the baseline were compared with those occurring two years after the baseline. Self-help subjects decreased their use of hospital stay as to number of admissions and days in hospital, with a reduction of costs; they were more satisfied as to work/education while non self-help matches presented an increase of unmet needs. Clinical and social outcome showed no significant difference. The findings suggest that consumer participation may possibly enhance the effects of psychiatric treatment on outcome.

A census-based socio-economic status (SES) index as a tool to examine the relationship between mental health services use and deprivation.

This paper discusses the development and application of a socio-economic status (SES) index, created to explore the relationship between socio-economic variables and psychiatric service use. The study was conducted in a community-based mental health service (CMHS) in Verona, Northern Italy, utilising service use data from 1996. An ecological SES index was constructed through a factor analysis from 1991 Census data, at census block level. Three factors reflected the following domains: the educational-employment sector (with four components), the relational network (with three components) and the material conditions (with three components). All service users were assigned a SES value, according to their place of residence in 1996. When these data were explored spatially, using ArcView 8.3, an association was observed between socio-economic deprivation and psychiatric service use. The SES index was then successfully validated using occupational status at the individual level. This study confirms the usefulness of developing and validating an ecological census-based SES index, for service planning and resource allocation in an area with a community-based system of mental health care.

Growing recognition of the importance of service user involvement in mental health service planning and evaluation.

Service user involvement in the planning and provision of mental health services has been growing over the last two decades, especially in countries and areas where institutional service provision has been changed to a community-orientated model of care. However, the material involvement of service users in mental health research is still in its infancy. The aim of this paper is to attempt to place these developments in a conceptual context, to summarise the ethics-based and evidence-based reasons why it has to be considered as necessary, and to illustrate some of the emerging evidence which shows the advantages to be gained from it. In particular the results of recent studies are briefly reported, showing that outcomes data rated by service users in some cases are more important than those rated by staff. The reduction in patient-rated unmet needs in the social domain was the strongest predictor of an increase in subjective quality of life. The importance of including service user preferences within the content of the research questions is exemplified by the results of a recent study that showed that joint crisis plans can significantly reduce the use of compulsory admission during crises and by a review that demonstrated that the use of an explicit service user perspective produced distinctive insights into the long-term effects of Electro-Convulsive Therapy (ECT).
