A review of studies of heavy users of psychiatric services

Cost structure in specialist mental healthcare: what are the main drivers of the most expensive episodes?

BACKGROUND

Mental disorders are one of the costliest conditions to treat in Norway, and research into the costs of specialist mental healthcare are needed. The purpose of this article is to present a cost structure and to investigate the variables that have the greatest impact on high-cost episodes.

METHODS

Patient-level cost data and clinic information during 2018-2021 were analyzed (N = 180,220). Cost structure was examined using two accounting approaches. A generalized linear model was used to explain major cost drivers of the 1%, 5%, and 10% most expensive episodes, adjusting for patients' demographic characteristics [gender, age], clinical factors [length of stay (LOS), admission type, care type, diagnosis], and administrative information [number of planned consultations, first hospital visits, interval between two hospital episode].

RESULTS

One percent of episodes utilized 57% of total resources. Labor costs accounted for 87% of total costs. The more expensive an episode was, the greater the ratio of the inpatient (ward) cost was. Among the top-10%, 5%, and 1% most expensive groups, ward costs accounted for, respectively, 89%, 93%, and 99% of the total cost, whereas the overall average was 67%. Longer LOS, ambulatory services, surgical interventions, organic disorders, and schizophrenia were identified as the major cost drivers of the total cost, in general. In particular, LOS, ambulatory services, and schizophrenia were the factors that increased costs in expensive subgroups. The "first hospital visit" and "a very short hospital re-visit" were associated with a cost increase, whereas "the number of planned consultations" was associated with a cost decrease.

CONCLUSIONS

The specialist mental healthcare division has a unique cost structure. Given that resources are utilized intensively at the early stage of care, improving the initial flow of hospital care can contribute to efficient resource utilization. Our study found empirical evidence that planned outpatient consultations may be associated with a reduced health care burden in the long-term.

Risk of psychiatric readmission in the homeless population: A 10-year follow-up study

Homelessness continues to be a major social and clinical problem. The homeless population has a higher burden of disease that includes psychiatric disorders. In addition, they have a lower use of ambulatory health services and a higher use of acute care. Few investigations analyze the use of services of this population group in the long term. We analyzed the risk of psychiatric readmission of homeless individuals through survival analysis. All admissions to a mental health hospitalization unit in the city of Malaga, Spain, from 1999 to 2005, have been analyzed. Three analyses were carried out: two intermediate analyses at 30 days and 1 year after starting follow-up; and one final analysis at 10 years. In all cases, the event was readmission to the hospitalization unit. The adjusted Hazard Ratio at 30 days, 1-year, and 10-year follow-ups were 1.387 (p = 0.027), 1.015 (p = 0.890), and 0.826 (p = 0.043), respectively. We have found an increased risk of readmission for the homeless population at 30 days and a decreased risk of readmission at 10 years. We hypothesize that this lower risk of long-term readmission may be due to the high mobility of the homeless population, its low degree of adherence to long-term mental health services, and its high mortality rate. We suggest that time-critical intervention programs in the short term could decrease the high rate of early readmission of the homeless population, and long-term interventions could link them with services and avoid its dispersion and abandonment.

The relationship between psychological characteristics of patients and their utilization of psychiatric inpatient treatment: A cross-sectional study, using machine learning

High utilizers (HU) are patients with an above-average use of psychiatric inpatient treatment. A precise characterization of this patient group is important when tailoring specific treatment approaches for them. While the current literature reports evidence of sociodemographic, and socio-clinical characteristics of HU, knowledge regarding their psychological characteristics is sparse. This study aimed to investigate the association between patients’ psychological characteristics and their utilization of psychiatric inpatient treatment. Patients from the University Psychiatric Clinics (UPK) Basel diagnosed with schizophrenia spectrum or bipolar affective disorders participated in a survey at the end of their inpatient treatment stay. The survey included assessments of psychological characteristics such as quality of life, self-esteem, self-stigma, subjective experience and meaning of psychoses, insight into the disease, and patients’ utilization of psychiatric inpatient treatment in the last 30 months. The outcome variables were two indicators of utilization of psychiatric inpatient treatment, viz. “utilization pattern” (defined as HU vs. Non-HU [NHU]) and “length of stay” (number of inpatient treatment days in the last 30 months). Statistical analyses included multiple regression models, the least absolute shrinkage and selection operator (lasso) method, and the random forest model. We included 112 inpatients, of which 50 were classified as HU and 62 as NHU. The low performance of all statistical models used after cross-validation suggests that none of the estimated psychological variables showed predictive accuracy and hence clinical relevance regarding these two outcomes. Results indicate no link between psychological characteristics and inpatient treatment utilization in patients diagnosed with schizophrenia spectrum or bipolar affective disorders. Thus, in this study, the examined psychological variables do not seem to play an important role in patients’ use of psychiatric inpatient treatment; this highlights the need for additional research to further examine underlying mechanisms of high utilization of psychiatric inpatient treatment.

Relationships Among Structures, Team Processes, and Outcomes for Service Users in Quebec Mental Health Service Networks

Background:

Few studies have identified and compared profiles of mental health service networks (MHSN) in terms of structures, processes, and outcomes, based on cluster analyses and perceptions of team managers, MH professionals and service users. This study assessed these associations in Quebec metropolitan, urban and semi-urban MHSN.

Methods:

A framework adapted from the Donabedian model guided data management, and cluster analyses were used to identify categories. Study participants included team managers (n = 45), MH professionals (n = 311) and service users (n = 327).

Results:

For all three MHSN, a common outcome category emerged: service users with complex MH problems and negative outcomes. The Metropolitan network reported two categories for structures (specialized MH teams, primary care MH teams) and processes (senior medical professional, psychosocial professionals), and outcomes (middle-age men with positive outcomes, older women with few MH problems). The Urban and Semi-urban networks revealed one category for structures (all teams) and service user (young service users with drug disorders), but two for processes (psychosocial professionals: urban, all professionals: semi-urban).

Conclusion:

The Metropolitan MHSN showed greater heterogeneity regarding structures and team processes than the other two MHSN. Service user outcomes were largely associated with clinical characteristics, regardless of network configurations for structures and team processes.

Prediction of in-patient use in first-admitted patients with psychosis

Purpose:

The aim of this study is to examine the utilization of psychiatric services for inpatients with psychosis over a period of five years after first admission, and to identify factors that contribute to intensive service use in terms of cumulative length of in-patient treatment and readmission rate.

Methods:

A cohort of 424 patients with psychotic disorders (out of a sample of 2565 first-admitted patients from a catchment area in Switzerland) was examined by means of register data.

Results:

Patients admitted for psychosis spent the longest time in hospital compared to other diagnoses, but there was considerable within-sample variation, and most patients (60.4%) had only one in-patient episode. Of the total time accumulated in this sample, 50.5% was ‘consumed’ by 10.7% of patients. Regarding the overlap between ‘heavy use’ and ‘frequent use’ (those 10% of the sample with the longest/ most frequent hospitalizations), only 39.5% of the ‘frequent users’ were also ‘heavy users’ (vice versa: 38.6%). ‘Clinical’ measures were the main predictors of the overall time spent as an in-patient (schizophrenia diagnosis, therapeutic measures, clinical improvement). Concerning ‘heavy use’, homelessness was yet another important risk factor. Sociodemographic variables (age, level of education, living alone) particularly influenced the number of hospitalizations. A younger age at first admission was predictive of ‘heavy’ and ‘frequent’ use.

Discussion:

Clinical and sociodemographic factors explain differences in in-patient service consumption among patients with psychosis. Efforts to devise effective interventions have to take both into account, but different measures are needed to address ‘heavy’ and ‘frequent’ use.

Peer support for frequent users of inpatient mental health care in Uganda: protocol of a quasi-experimental study

BACKGROUND

Reducing readmissions among frequent users of psychiatric inpatient care could result in substantial cost savings to under-resourced mental health systems. Studies from high-income countries indicate that formal peer support can be an effective intervention for the reduction of readmissions among frequent users. Although in recent years formal peer support programmes have been established in mental health services in a few low- and middle-income countries (LMICs), they have not been rigorously evaluated.

METHODS

This protocol describes a quasi-experimental difference-in-differences study conducted as part of a broader evaluation of the Brain Gain II peer support programme based at Butabika National Referral Hospital in Kampala, Uganda. The primary objective is to investigate whether frequent users of psychiatric inpatient care who have access to a peer support worker (PSW+) experience a greater reduction in rehospitalisation rates and number of days spent in hospital compared to those who do not have access to a peer support worker (PSW-). Frequent users, defined as adults diagnosed with either a mental disorder or epilepsy who have had three or more inpatient stays at Butabika over the previous 24 months, are referred to Brain Gain II by hospital staff on five inpatient wards. Frequent users who normally reside in a district where peer support workers currently operate (Kampala, Jinja, Wakiso and Mukono) are eligible for formal peer support and enter the PSW+ group. Participants in the PSW+ group are expected to receive at least one inpatient visit by a trained peer support worker before hospital discharge and three to six additional visits after discharge. Frequent users from other districts enter the PSW- group and receive standard care. Participants' admissions data are extracted from hospital records at point of referral and six months following referral.

DISCUSSION

To the best of our knowledge, this will be the first quasi-experimental study of formal peer support in a LMIC and the first to assess change in readmissions, an outcome of particular relevance to policy-makers seeking cost-effective alternatives to institutionalised mental health care.

Reflecting on Participatory, Action-Oriented Research Methods in Community Psychology: Progress, Problems, and Paths Forward

This paper provides a critical reflection on participatory action research (PAR) methods as they pertain to community psychology. Following a brief review of the fundamental aspects of PAR, key developments in the field are examined. These developments include the redefinition of the research enterprise among groups such as Indigenous and consumer/survivor communities, challenges that attend the "project" framing of PAR, academic and practice context challenges, and important domains in which PAR methods need to become more engaged (e.g., social media and disenfranchised youth). Three illustrative case studies of programs of work in the areas of youth homelessness, consumer/survivor engagement, and Indigenous research are provided to illustrate these contemporary challenges and opportunities in the field. The authors make the argument that without an effort to reconsider and redefine PAR, moving away from the stereotypical PAR "project" frame, these methods will continue to be poorly represented and underutilized in community psychology.

Risk Factors for Psychiatric Hospital Admission for Participants in California's Full-Service Partnership Program

This study investigated the demographic and clinical predictors of psychiatric hospitalization during the first 2 years of treatment for adults participating in the full-service partnership (FSP) program, based on Assertive Community Treatment, in a large county in northern California. Clinical and demographic characteristics, data on prior hospitalizations, length of enrollment, and living situation for 328 FSP participants were collected from the county's internal billing system and the California Department of Health Care Services. In univariate models, the probability of hospitalization varied by diagnosis, age, and hospitalization history. In the multivariate model, younger age and frequent hospitalization prior to enrollment predicted hospitalization during enrollment. Findings support prior research on hospital recidivism and may be beneficial in refining future strategies for meeting the needs of adults with serious mental illness.

Heterogeneity of Mental Health Service Utilization and High Mental Health Service Use Among Women Eight Years After Initiating Substance Use Disorder Treatment

OBJECTIVE

The aim of this study was to determine mental health service utilization patterns among women treated for substance use disorders (SUD) and identify factors associated with patterns of high mental health service use.

METHODS

Data were provided by 4447 women treated for SUD in California during 2000-2002 for whom mental health services utilization records were acquired. A latent class model was fitted to women's high use of services (>6 services/year over 8 years). Multinomial logistic regression was used to identify predisposing, enabling, and need factors associated with utilization patterns.

RESULTS

In 8 years after initiating SUD treatment, 50% of women utilized mental health services. High use probability was consistently low for most women (76.9%); for others, however, it decreased immediately following SUD treatment and then increased over time (8.7%), increased immediately following SUD treatment and then decreased (9.3%), or remained consistently high (5.1%). Consistently high services use was negatively associated with marriage (OR 0.60, p<0.05) and employment (OR 0.53, p<0.05) and positively associated with older age (OR 1.04, p<0.001), homelessness (OR 1.68, p<0.05), public assistance (OR 1.76, p<0.01), outpatient SUD treatment (OR 3.69, p<0.01), longer SUD treatment retention (OR 1.00, p<0.01), treatment desire (ORs 1.46, p<0.001), and co-occurring disorder diagnosis (ORs 2.89-44.93, p<0.001). Up to 29% of women with co-occurring mental health disorders at SUD treatment entry did not receive any mental health treatment in the subsequent 8 years.

CONCLUSIONS

Mental health services utilization patterns among women treated for SUD are heterogeneous and dynamic. Understanding factors related to women's utilization patterns may aid efforts to optimize care and ensure appropriate use of mental health services.

A systematic review of the predictors of health service utilisation by adults with mental disorders in the UK

OBJECTIVES

To identify variables that predict health service utilisation (HSU) by adults with mental disorders in the UK, and to determine the evidence level for these predictors.

DESIGN

A narrative synthesis of peer-reviewed studies published after the year 2000. The search was conducted using four databases (ie, PsycINFO, CINAHL Plus with full text, MEDLINE and EMBASE) and completed on 25 March 2014.

SETTING

The majority of included studies were set in health services across primary, secondary, specialist and inpatient care. Some studies used data from household and postal surveys.

PARTICIPANTS

Included were UK-based studies that predicted HSU by adults with mental disorders. Participants had a range of mental disorders including psychotic disorders, personality disorders, depression, anxiety disorders, eating disorders and dementia.

PRIMARY OUTCOME

A wide range of HSU outcomes were examined, including general practitioner (GP) contacts, medication usage, psychiatrist contacts, psychotherapy attendances, inpatient days, accident and emergency admissions and 'total HSU'.

RESULTS

Taking into account study quality, 28 studies identified a range of variables with good preliminary evidence supporting their ability to predict HSU. Of these variables, comorbidity, personality disorder, age (heterogeneous age ranges), neurotic symptoms, female gender, a marital status of divorced, separated or widowed, non-white ethnicity, high previous HSU and activities of daily living, were associated with increased HSU. Moreover, good preliminary evidence was found for associations of accessing a primary care psychological treatment service and medication use with decreased HSU.

CONCLUSIONS

The findings can inform decisions about which variables might be used to derive mental health clusters in 'payment by results' systems in the UK. The findings also support the need to investigate whether combining broad diagnoses with care pathways is an effective method for mental health clustering, and the need for research to further examine the association between mental health clusters and HSU.

Predictors of frequent recourse to health professionals by people with severe mental disorders

OBJECTIVE

Based on Andersen's behavioural model, our study sought to determine predictors and blocks of factors that could explain why people with severe mental disorders (SMDs) more often seek the services of health professionals.

METHODS

This longitudinal study involved 292 users with SMDs located in Le Sud-Ouest, the southwest borough of Montreal. Data were collected from participants' medical records and through 7 questionnaires. Using Andersen's Behavioral Model of Health Services Use, independent variables were divided into 3 classes-predisposing factors, enabling factors, and need factors-and were introduced in this order in a hierarchical logistic model.

RESULTS

Among 292 users, 110 (37.7%) were frequent users who consulted about one health professional every 3 days. Participants who were more likely to call on health professionals were single and older, depended on welfare as their main source of income, lived in supervised housing, suffered from schizophrenia, schizophrenia spectrum disorders, and adjustment disorders, and, marginally, exhibited multiple mental disorders.

CONCLUSION

Mental health services could promote strategies to overcome the reluctance of younger people to seek professional services. Professionals should pay close attention to subsidiary conditions, such as adjustment disorders, from which people with SMDs may suffer. Interventions to improve the socioeconomic condition of unemployed people with SMDs may help to reduce health care service use among that clientele. Programs such as supported employment should be tailored and enhanced for people receiving welfare to decrease stigmatization and improve job market integration.

[Heavy users of inpatient services: a comparison of diagnostic subgroups]

OBJECTIVE

Quantitative and qualitative assessment of heavy users (HU) of psychiatric inpatient treatment.

METHODS

Screening over 9 months for patients with ≥ 3 admissions or ≥ 100 days of treatment during 1 year prior to index admission.

RESULTS

During the recruiting period 1217 persons were treated of whom 132 (10.8 %) fulfilled HU criteria. Patients belonged most often to the diagnostic group F2 (43 %), followed by F1 (21 %) and F3 (17 %). HU were most common within the diagnostic group F6 (33 %), next to F2 (21 %), F1 (9 %) and F3 (6 %). HU had signs of more severe illness compared to the other patients: only 8 % held a job and 73 % ware on a disablement pension, patients with a diagnosis of F2 faring worst. HU were treated more frequently involuntarily (50.5 vs 30.7 %). An office-based physician referred only 5 % of the patients and almost half attended the clinic without any referral. HU participated only to a modest degree in community-based treatments and 37 % attended no doctor in the month prior to admission. During the year following the index admission more than 80 % of HU were admitted again and were hospitalized almost as many days as before the index admission. Patients with a diagnosis of F1 and F2 showed the greatest persistence of heavy use behavior.

CONCLUSIONS

This sample of HU show a persistent pattern of use of psychiatric inpatient treatment. Strategies to improve the situation are discussed.

Determinants and patterns of service utilization and recourse to professionals for mental health reasons

Background

This study has a dual purpose: 1) identify determinants of healthcare service utilization for mental health reasons (MHR) in a Canadian (Montreal) catchment area; 2) determine the patterns of recourse to healthcare professionals in terms of frequency of visits and type of professionals consulted, and as it relates to the most prevalent mental disorders (MD) and psychological distress.

Methods

Data was collected from a random sample of 1,823 individuals interviewed after a two-year follow-up period. A regression analysis was performed to identify variables associated with service utilization and complementary analyses were carried out to better understand participants’ patterns of healthcare service utilization in relation to the most prevalent MD.

Results

Among 243 individuals diagnosed with a MD in the 12 months preceding an interview, 113 (46.5%) reported having used healthcare services for MHR. Determinants of service utilization were emotional and legal problems, number of MD, higher personal income, lower quality of life, inability of individuals to influence events occurring in their neighborhood, female gender and, marginally, lack of alcohol dependence in the past 12 months. Emotional problems were the most significant determinant of healthcare service utilization. Frequent visits with healthcare professionals were more likely associated with major depression and number of MD with or without dependence to alcohol or drugs. People suffering from major depression, psychological distress and social phobia were more likely to consult different professionals, while individuals with panic disorders relied on their family physician only. Concerning social phobia, panic disorders and psychological distress, more frequent visits with professionals did not translate into involvement of a higher number of professionals or vice-versa.

Conclusions

This study demonstrates the impact of emotional problems, neighborhood characteristics and legal problems in healthcare service utilization for MHR. Interventions based on inter-professional collaboration could be prioritized to increase the ability of healthcare services to take care especially of individuals suffering from social phobia, panic disorders and psychological distress. Others actions that could be prioritized are training of family physicians in the treatment of MD, use of psychiatric consultants, internet outreach, and reimbursement of psychological consultations for individuals with low income.

Sustained unemployment in psychiatric outpatients with bipolar depression compared to major depressive disorder with comorbid borderline personality disorder

OBJECTIVES

The morbidity associated with bipolar disorder is, in part, responsible for repeated calls for improved detection and recognition. No such clinical commentary exists for improved detection of borderline personality disorder in depressed patients. Clinical experience suggests that borderline personality disorder is as disabling as bipolar disorder; however, no studies have directly compared the two disorders. For this reason we undertook the current analysis from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project comparing unemployment and disability rates in patients with bipolar disorder and borderline personality disorder.

METHODS

Patients were interviewed with semi-structured interviews. We compared three non-overlapping groups of depressed patients: (i) 181 patients with DSM-IV major depressive disorder and borderline personality disorder, (ii) 1068 patients with major depressive disorder without borderline personality disorder, and (iii) 84 patients with bipolar depression without borderline personality disorder.

RESULTS

Compared to depressed patients without borderline personality disorder, depressed patients with borderline personality disorder were significantly more likely to have been persistently unemployed. A similar difference was found between patients with bipolar depression and major depressive disorder without borderline personality disorder. No differences were found between patients with bipolar depression and depression with borderline personality disorder.

CONCLUSIONS

Both bipolar disorder and borderline personality disorder were associated with impaired occupational functioning and thus carry a significant public health burden. Efforts to improve detection of borderline personality disorder in depressed patients might be as important as the recognition of bipolar disorder.

Course, outcomes, and psychosocial interventions for first-episode mania

OBJECTIVES

The course of bipolar disorder tends to worsen over time, highlighting the importance of early intervention. Despite the recognized need for adjunctive psychosocial treatments in first-episode mania, very few studies have evaluated psychological interventions for this period of significant risk. In this empirical review, we evaluate existing research on first-episode bipolar disorder, compare this body of research to parallel studies of first-episode schizophrenia, and identify strategies for future research.

METHODS

A comprehensive literature search of the MEDLINE and PsychINFO databases was conducted to identify studies of first-episode mania, as well as first-episode schizophrenia. Recovery and relapse rates were compared across studies.

RESULTS

In contrast to a number of studies of first-episode schizophrenia, the authors identified only seven independent programs assessing first-episode mania. Findings from these studies suggest that, while pharmacological treatment helps patients achieve recovery from acute episodes, it fails to bring patients to sustained remission. Early psychosocial intervention may be imperative in reducing residual symptoms, preventing recurrence of mood episodes, and improving psychosocial functioning. However, very few studies of psychosocial interventions for first-episode mania have been systematically studied.

CONCLUSIONS

Studies of first-episode mania indicate a gap between syndromal/symptomatic and functional recovery. Novel psychosocial interventions for first-episode mania may help bridge this gap, but require controlled study.

Comprehensive determinants of health service utilisation for mental health reasons in a Canadian catchment area

INTRODUCTION

This study sought to identify factors associated with health service utilisation by individuals with mental disorders in a Canadian catchment area.

METHODS

To be included in the study, participants had to be aged between 15 and 65 and reside in the study location. Data was collected randomly from June to December 2009 by specially trained interviewers. A comprehensive set of variables (including geospatial factors) was studied using the Andersen's behavioural health service model. Univariate, bivariate, and multivariate analyses were carried out.

RESULTS

Among 406 individuals diagnosed with mental disorders, 212 reported using a mental health service at least once in the 12 months preceding the interviews. Emotional problems and a history of violence victimisation were most strongly associated with such utilisation. Participants who were middle-aged or deemed their mental health to be poor were also more likely to seek mental healthcare. Individuals living in neighbourhoods where rental accommodations were the norm used significantly fewer health services than individuals residing in neighbourhoods where homeownership was preponderant; males were also less likely to use services than females.

CONCLUSIONS

Our study broke new ground by uncovering the impact of longstanding violence victimisation, and the proportion of homeownership on mental health service utilisation among this population. It also confirmed the prominence of some variables (gender, age, emotional problems and self-perceived mental health) as key enabling variables of health-seeking. There should be better promotion of strategies designed to change the attitudes of males and youths and to deal with violence victimisation. There is also a need for initiatives that are targeted to neighbourhoods where there is more rental housing.

A multi-level study of the determinants of mental health service utilization

BACKGROUND

Until now, research has focused on neighbourhood variations in mental health services and their relationships with local attributes, such as healthcare supply and socio-economic deprivation, without controlling for individual characteristics (age, sex, income, or education, for instance). Hence, this study is a major attempt to clarify the role played by individual and local attributes in the utilization of mental health services. The aim of this study was to disentangle individual and neighbourhood effects on mental health service use.

METHODS

In this cross-sectional study, individual-level data on 423 participants with a frequent mental health disorder was recruited from the general population and linked to neighbourhood-level data at the census tract level from the 2006 Canadian Census. Neighbourhood variables included socio-economic deprivation, mean income, residential stability and the proportion of recent immigrants. Individual characteristics included gender, age, marital status, self-rated mental health and the number of diagnoses. Multi-level logistic regression was used to assess the effects of individual and neighbourhood characteristics simultaneously on mental health service use.

RESULTS

The intraclass correlation coefficient indicated that 12.26% of the variance of mental health service utilization is at the neighbourhood level. Final analysis showed that at the individual level, being female, married, or self-rating mental health less than excellent increased healthcare use. At the neighbourhood level, deprived socio-economic neighbourhood decreased health service use (OR=0.71, P<0.05), while residential stability increased use (OR=1.24, P<0.05).

CONCLUSIONS

Individual and neighbourhood characteristics determine mental health service utilization. Taking both into consideration allows better targeting of health service policy and planning and enables more accurate needs-based resource allocation. However, future research should continue to investigate the pathway through which neighbourhood affects health service utilization.

Patterns of mental health care utilisation: distribution of services and its predictability from routine data

OBJECTIVES

Explore if a multi-dimensional analytic approach to routinely registered data provides a comprehensive way to characterise utilisation patterns, and to test if the patients' functional status is a predictor for the use of services.

METHOD

We linked register contact data during a two-year period, including all types of specialised mental health services, in the population of a Norwegian county. Cox regression was applied in the models for prediction of admission and readmission.

RESULTS

Great variability and complexity in patterns of utilisation were found, including multiple transitions between in-patient and out-patient statuses. The distribution of services was characterised by a small group of patients receiving a disproportionally large amount of resources. A majority of 77% appeared as out-patients only. Severity of symptoms as well as of dysfunction, as assessed by the split GAF-score, differentiated amongst utilisation groups. Both dimensions were significant predictors for admission. In contrast, only the severity of dysfunction predicted readmission.

CONCLUSION

Multi-dimensional data architecture and analytical perspectives can be applied to routine data, and should be used to analyse the diverse patterns of utilisation. Risk populations could be predicted by routinely registered information on functional status.

Are screening scales for bipolar disorder good enough to be used in clinical practice?

Bipolar disorder is often underdiagnosed. Recommendations for improving the detection of bipolar disorder include the use of screening questionnaires. The most widely studied screening scale is the Mood Disorders Questionnaire (MDQ). Studies of the performance of the MDQ in heterogeneous samples of psychiatric outpatients presenting for treatment have raised concerns about the adequacy of the MDQ as a screening measure because of its relatively low sensitivity. The sensitivity of a scale is not an inherent property of the instrument but depends on the threshold used to identify positive cases. Prior studies used the scoring recommendations of the developers of the MDQ to examine its performance; none examined the performance of the scale across the range of cutoff scores to determine whether a lower threshold would be more appropriate for the purposes of screening. The goal of the present study was to examine the operating characteristics of the MDQ at all cutoff scores to determine the cutoff point that would be appropriate for the purpose of screening. Seven hundred fifty-two psychiatric outpatients were interviewed with the Structured Clinical Interview for DSM-IV, and completed the MDQ. When MDQ caseness was based only on symptom score without regard to level of impairment, the cutoff score associated with at least 90% sensitivity was 5. At this cutoff the specificity of the MDQ was 60.7%, and its positive predictive value was 22.1%. These findings indicate that when the cutoff to identify cases on the MDQ was set to achieve a desired level of sensitivity as a screening instrument most cases screening positive on the scale did not have bipolar disorder. Low positive predictive value does not support the use of the MDQ or any bipolar disorder screening scale in psychiatric clinical practice.

Factors associated with use of community mental health services by schizophrenia patients using multilevel analysis

Background

Persons with schizophrenia and related disorders may be particularly sensitive to a number of determinants of service use, including those related with illness, socio-demographic characteristics and organizational factors. The objective of this study is to identify factors associated with outpatient contacts at community mental health services of patients with schizophrenia or related disorders.

Methods

This cross-sectional study analyzed 1097 patients. The main outcome measure was the total number of outpatient consultations during one year. Independent variables were related to socio-demographic, clinical and use of service factors. Data were collected from clinical records.

Results

The multilevel linear regression model explained 46.35% of the variance. Patients with significantly more contacts with ambulatory services were not working and were receiving welfare benefits (p = 0.02), had no formal education (p = 0.02), had a global level of severity of two or three (four being the most severe) (p < 0.001), with one or more inpatient admissions (p < 0.001), and in contact with both types of professional (nurses and psychiatrists) (p < 0.001). The patients with the fewest ambulatory contacts were those with diagnoses of persistent delusional disorders (p = 0.04) and those who were attended by four of the 13 psychiatrists (p < 0.001).

Conclusions

As expected, the variables that explained the use of community service could be viewed as proxies for severity of illness. The most surprising finding, however, was that a group of four psychiatrists was also independently associated with use of ambulatory services by patients with schizophrenia or related disorders. More research is needed to carefully examine how professional support networks interact to affect use of mental health.

Mental health service utilization among patients with severe mental disorders

In light of healthcare reforms, the study aims to assess variables associated with mental healthcare service utilization in general and in both primary and specialized care by patients with severe mental disorders (SMD, mainly schizophrenia). The study is based on a sample of 140 patients with SMD from five regions in Quebec (Canada). Variables were organized in accordance with Andersen's conceptual model into four factors: predisposing, enabling, needs, and service utilization. Secondary analyses were also conducted comparing patients who were hospitalized or used emergency rooms (H.ER-Group) with patients who did not use such services (WH.ER-Group). Accessibility of services, continuity of care, and having a case manager appear to be core variables that enable service utilization. Compared with the WH.ER-Group, the H.ER-Group used twice as many services. The study highlights the importance of developing a gamut of coordinated services, easily accessible in local networks, including case managers, family physicians, and shared-care development.

Needs-oriented discharge planning for high utilisers of psychiatric services: multicentre randomised controlled trial

AIMS

Attempts to reduce high utilisation of mental health inpatient care by targeting the critical time of hospital discharge are rare. In this study, we test the effect of a needs-oriented discharge planning intervention on number and duration of psychiatric inpatient treatment episodes (primary), as well as on outpatient service use, needs, psychopathology, depression and quality of life (secondary).

METHODS

Four hundred and ninety-one adults with a defined high utilisation of mental health care gave informed consent to participate in a multicentre RCT carried out at five psychiatric hospitals in Germany (Düsseldorf, Greifswald, Regensburg, Ravensburg and Günzburg). Subjects allocated to the intervention group were offered a manualised needs-led discharge planning and monitoring intervention with two intertwined sessions administered at hospital discharge and 3 months thereafter. Outcomes were assessed at four measurement points during a period of 18 months following discharge.

RESULTS

Intention-to-treat analyses showed no effect of the intervention on primary or secondary outcomes.

CONCLUSIONS

Process evaluation pending, the intervention cannot be recommended for implementation in routine care. Other approaches, e.g. team-based community care, might be more beneficial for people with persistent and severe mental illness.

Typology of adults diagnosed with mental disorders based on socio-demographics and clinical and service use characteristics

BACKGROUND

Mental disorder is a leading cause of morbidity worldwide. Its cost and negative impact on productivity are substantial. Consequently, improving mental health-care system efficiency - especially service utilisation - is a priority. Few studies have explored the use of services by specific subgroups of persons with mental disorder; a better understanding of these individuals is key to improving service planning. This study develops a typology of individuals, diagnosed with mental disorder in a 12-month period, based on their individual characteristics and use of services within a Canadian urban catchment area of 258,000 persons served by a psychiatric hospital.

METHODS

From among the 2,443 people who took part in the survey, 406 (17%) experienced at least one episode of mental disorder (as per the Composite International Diagnostic Interview (CIDI)) in the 12 months pre-interview. These individuals were selected for cluster analysis.

RESULTS

Analysis yielded four user clusters: people who experienced mainly anxiety disorder; depressive disorder; alcohol and/or drug disorder; and multiple mental and dependence disorder. Two clusters were more closely associated with females and anxiety or depressive disorders. In the two other clusters, males were over-represented compared with the sample as a whole, namely, substance abuses with or without concomitant mental disorder. Clusters with the greatest number of mental disorders per subject used a greater number of mental health-care services. Conversely, clusters associated exclusively with dependence disorders used few services.

CONCLUSION

The study found considerable heterogeneity among socio-demographic characteristics, number of disorders, and number of health-care services used by individuals with mental or dependence disorders. Cluster analysis revealed important differences in service use with regard to gender and age. It reinforces the relevance of developing targeted programs for subgroups of individuals with mental and/or dependence disorders. Strategies aimed at changing low service users' attitude (youths and males) or instituting specialised programs for that particular clientele should be promoted. Finally, as concomitant disorders are frequent among individuals with mental disorder, psychological services and/or addiction programs must be prioritised as components of integrated services when planning treatment.

What makes community psychiatric nurses label non-psychotic chronic patients as 'difficult': patient, professional, treatment and social variables

PURPOSE

To determine which patient, professional, treatment and/or social variables make community psychiatric nurses (CPNs) label non-psychotic chronic patients as 'difficult'.

METHODS

A questionnaire was designed and administered to 1,946 CPNs in the Netherlands. Logistic regression was used to design models that most accurately described the variables that contributed to perceived difficulty.

RESULTS

Six variables were retained in the final logistic model. Perception-related variables (feeling powerless, feeling that the patient is able but unwilling to change, and pessimism about the patient's change potential) dominated treatment-related variables (number of contacts per week and admission to a locked ward in the last year) and social variables (number of psychosocial problems).

CONCLUSION

This research shows that perceived difficulty is related to complex treatment situations, not so much to individual patient characteristics. If the constructed model has good predictive qualities, which remains to be tested in longitudinal research, it may be possible to accurately predict perceived patient difficulty. When used as a screening tool, such a model could improve treatment outcomes.

Predicting time to readmission in patients with recent histories of recurrent psychiatric hospitalization: a matched-control survival analysis

The most robust predictor of future psychiatric hospitalization is the number of previous admissions. About half of psychiatric inpatients with histories of repeated hospitalizations are readmitted within 12 months. This study sought to determine which patient characteristics predicted time-to-readmission within 12 months after controlling for the number of previous hospitalizations in 75 adults with recent histories of recurrent admissions and 75 matched controls. Results revealed multiple clinical and demographic between-group differences at index hospitalization. However, the only predictors of shorter time-to-readmission in multivariate Cox proportional hazards were unemployment (hazards ratio = 9.26) and residential living status (hazards ratio = 2.05) after controlling for prior hospitalizations (hazard ratio = 1.24). Unemployment and residential living status were not proxies of psychosis or moderated by illness severity or comorbid substance use. Results suggest that early psychiatric readmission may be more influenced by residential and employment status than by severe mental illness.

Ineffective chronic illness behaviour in a patient with long-term non-psychotic psychiatric illness

This case report offers a different perspective on a patient with a long-term non-psychotic psychiatric disorder that was difficult to specify. The patient, a man in his 50s, was unable to profit from outpatient treatment and became increasingly dependent on mental healthcare - which could not be understood based on his history and psychiatric symptoms alone. By separating symptoms from illness behaviour, the negative course of this patient's treatment is analysed. Focusing on ineffective chronic illness behaviour by the patient, and mutual ineffective treatment behaviour by the clinicians, it becomes clear that basic requirements of effective treatment were unmet. By making a proper diagnosis, clarifying expectations and offering a suitable therapy, ineffective illness behaviour was diminished and this 'difficult' case became much easier for both patient and clinicians. The illness behaviour framework offers a useful, systematic tool to analyse difficulties between patients and clinicians beyond psychiatric symptoms or explanations.

Sustained unemployment in psychiatric outpatients with bipolar disorder: frequency and association with demographic variables and comorbid disorders

OBJECTIVES

The negative impact of bipolar disorder on occupational functioning is well established. However, few studies have examined the persistence of unemployment, and no studies have examined the association between diagnostic comorbidity and sustained unemployment. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we described the amount of time unemployed in the five years before the evaluation in a large cohort of outpatients diagnosed with bipolar disorder, and determined the demographic and clinical correlates of sustained unemployment.

METHODS

A total of 206 patients diagnosed with DSM-IV bipolar I or bipolar II disorder were interviewed with semi-structured interviews assessing comorbid Axis I and Axis II disorders, demographic and clinical variables. The interview included an assessment of the amount of time missed from work due to psychiatric reasons during the past five years. Persistent unemployment was defined as missing up to two years or more from work.

RESULTS

Less than 20% of the patients reported not missing any time from work due to psychiatric reasons, and more than one-third missed up to two years or more from work. Prolonged unemployment was associated with increased rates of current panic disorder and a lifetime history of alcohol abuse or dependence. Patients with prolonged unemployment were older and experienced more episodes of depression.

CONCLUSIONS

Most patients presenting for the treatment of bipolar disorder have missed some time from work due to psychiatric reasons, and the persistence of employment problems is considerable. Comorbid psychiatric disorders are a potentially treatable risk factor for sustained unemployment. It is therefore of public health significance to determine if current treatments are effective in bipolar disorder patients with current panic disorder, and if not, to attempt to develop treatments that are effective.

Overdiagnosis of bipolar disorder and disability payments

The diagnosis of bipolar disorder has received increasing attention during the past decade. Several research reports have suggested that bipolar disorder is under-recognized, and that many patients, particularly those with major depressive disorder, have, in fact, bipolar disorder. More recently, some reports have suggested that bipolar disorder is also overdiagnosed at times. There are several possible reasons for bipolar disorder overdiagnosis. In the present study, we examined whether secondary gain associated with receiving disability payments might be partially responsible for bipolar disorder overdiagnosis. A total of 82 psychiatric outpatients reported having been previously diagnosed with bipolar disorder, which was not confirmed when interviewed with the Structured Clinical Interview for DSM-IV. The percentage of patients receiving disability payments and the duration of disability payments were compared in these 82 patients and 528 patients who were not diagnosed with bipolar disorder. Compared with the patients who had never been diagnosed with bipolar disorder, the patients overdiagnosed with bipolar disorder were significantly more likely to have received disability payments at some point during the past 5 years, and were receiving disability payments for significantly more weeks. We conducted a regression analysis controlling for the number of lifetime diagnoses, and overdiagnosis of bipolar disorder was a significant predictor of disability status (OR = 3.8; 95% CI, 1.6-8.8). Thus, an unconfirmed diagnosis of bipolar disorder was significantly associated with receiving disability benefits.

Professional service utilisation among patients with severe mental disorders

BACKGROUND

Generally, patients with serious mental disorders (SMD) are frequent users of services who generate high care-related costs. Current reforms aim to increase service integration and primary care for improved patient care and health-care efficiency. This article identifies and compares variables associated with the use by patients with SMD of services offered by psychiatrists, case managers, and general practitioners (GPs). It also compares frequent and infrequent service use.

METHOD

One hundred forty patients with SMD from five regions in Quebec, Canada, were interviewed on their use of services in the previous year. Patients were also required to complete a questionnaire on needs-assessment. In addition, data were collected from clinical records. Descriptive, bivariate, and multivariate analyses were conducted.

RESULTS

Most patients used services from psychiatrists and case managers, but no more than half consulted GPs. Most patients were followed at least by two professionals, chiefly psychiatrists and case managers. Care access, continuity of care, and total help received were the most important variables associated with the different types of professional consultation. These variables were also associated with frequent use of professional service, as compared with infrequent service use. In all, enabling factors rather than need factors were the core predictors of frequency of service utilisation by patients with SMD.

CONCLUSION

This study reveals that health care system organisation and professional practice--rather than patient need profiles--are the core predictors of professional consultation by patients with SMD. The homogeneity of our study population, i.e. mainly users with schizophrenia, recently discharged from hospital, may partly account for these results. Our findings also underscored the limited involvement of GPs in this patient population's care. As comorbidity is often associated with serious mental disorders, closer follow-up by GPs is needed. Globally, more effort should be directed at increasing shared-care initiatives, which would enhance coordination among psychiatrists, GPs, and psychosocial teams (including case managers). Finally, there is a need to increase awareness among health care providers, especially GPs, of the level of care required by patients with disabling and serious mental disorders.

The future of community-centred health services in Australia: lessons from the mental health sector

•It is apparent that hospital-dominated health care produces limited health outcomes and is an unsustainable health care system strategy. •Community-centred health care has been demonstrated to be a more cost-efficient and cost-effective alternative to hospital-centred care, particularly for prevention and care of persistent, long-term or recurrent conditions. Nevertheless, hospital-centred services continue to dominate health care services in Australia, and some state governments have presided over a retreat from, or even dismantling of, community health services. •The reasons for these trends are explored. •The future of community health services in Australia is uncertain, and in some states under serious threat. We consider lessons from the partial dismantling of Australian community mental health services, despite a growing body of Australian and international studies finding in their favour. •Community-centred health services should be reconceptualised and resourced as the centre of gravity of local, effective and affordable health care services for Australia. A growing international expert consensus suggests that such community-centred health services should be placed in the centre of their communities, closely linked or collocated where possible with primary health care, and functionally integrated with their respective hospital-based services. What is known about the topic?Community-centred health care has been widely demonstrated to be a more cost-efficient and cost-effective alternative to hospital-centred care, particularly for prevention and care of persistent, long-term or recurrent conditions, e.g. in mental health service systems. A growing international expert consensus suggests that such community-centred health services should be placed in the centre of their communities, closely linked or collocated where possible with primary health care, and functionally integrated with their respective hospital-based services. What does this paper add?Despite this global consensus, hospital-centred services continue to dominate health care services in Australia, and some state governments have presided over a retreat from, or even dismantling of, community health services. The reasons for these trends and possible solutions are explored. What are the implications for practitioners?Unless this trend is reversed, the loss of convenient public access to community health services at shopping and transport hubs and the consequent compromising of intensive home-based clinical care, will lead to a deterioration of preventative interventions and the health care of long-term conditions, contrary to international studies and reviews.

The role of depression, shame-proneness, and guilt-proneness in predicting criticism of relatives towards people with bipolar disorder

Expressed emotion (EE) has been associated with poor patient outcomes in many different psychiatric disorders. Given its robust association with relapse, EE has become a major target of family psychoeducational interventions. Most psychoeducational interventions to date have failed to change EE levels among families of those with bipolar disorder. Better intervention strategies, then, may depend on an increased understanding of the predictors of EE. Although EE has traditionally included many facets, criticism appears to be the most robust predictor of outcome within bipolar disorder. The present study tested three primary predictors of criticism among family members of people with bipolar disorder: shame-proneness, guilt-proneness, and depression. Depressive symptoms were significantly associated with EE. Discussion focuses on limitations and implications of the study and suggestions for future research.

Needs-oriented discharge planning and monitoring for high utilisers of psychiatric services (NODPAM): design and methods

Background

Attempts to reduce high utilisation of psychiatric inpatient care by targeting the critical time of hospital discharge have been rare.

Methods

This paper presents design and methods of the study "Effectiveness and Cost-Effectiveness of Needs-Oriented Discharge Planning and Monitoring for High Utilisers of Psychiatric Services" (NODPAM), a multicentre RCT conducted in five psychiatric hospitals in Germany. Inclusion criteria are receipt of inpatient psychiatric care, adult age, diagnosis of schizophrenia or affective disorder, defined high utilisation of psychiatric care during two years prior to the current admission, and given informed consent. Consecutive recruitment started in April 2006. Since then, during a period of 18 months, comprehensive outcome data of 490 participants is being collected at baseline and during three follow-up measurement points.

The manualised intervention applies principles of needs-led care and focuses on the inpatient-outpatient transition. A trained intervention worker provides two intervention sessions: (a) Discharge planning: Just before discharge with the patient and responsible clinician at the inpatient service; (b) Monitoring: Three months after discharge with the patient and outpatient clinician. A written treatment plan is signed by all participants after each session.

Primary endpoints are whether participants in the intervention group will show fewer hospital days and readmissions to hospital. Secondary endpoints are better compliance with aftercare, better clinical outcome and quality of life, as well as cost-effectiveness and cost-utility.

Discussion

If a needs-oriented discharge planning and monitoring proves to be successful in this RCT, a tool will be at hand to improve patient outcome and reduce costs via harmonising fragmented mental health service provision.

Time to rehospitalization of clozapine versus risperidone in the naturalistic treatment of comorbid alcohol use disorder and schizophrenia

Clozapine is known to be effective in treating schizophrenia patients with comorbid alcohol use disorders (AUD). However, few prospective studies have examined the effect of clozapine on community survival of the patient, which is one of the most important indicators of success for patients with schizophrenia. In this prospective, naturalistic, observational, community-survival-analysis study, we compared the effect of clozapine and risperidone on two-year psychiatric hospitalization rate and time to hospitalization in the treatment of patients with schizophrenia and comorbid AUD. We found that the clozapine treated patients were readmitted to hospital significantly later (mean survival=526.5 days, n=25 patients) than the risperidone treated patients (mean survival=420.4 days, n=36 patients). The survival curve for the clozapine-treated patients was significantly different from that of the risperidone treated patients (log-rank test, df=1, p=.045). At the end of the two-year study period, 75% of the risperidone treated patients had been admitted to the hospital, compared to only 48% of the clozapine treated patients. These findings suggest that clozapine should be considered for the treatment of schizophrenia patients with comorbid AUD. However, due to the limitations of this study, further studies will be required to confirm these findings.

Unmet needs and treatment seeking in high users of mental health services: role of illness perceptions

OBJECTIVE

A small number of patients tend to use a disproportionately high amount of mental health services. Understanding the needs and behaviours of this group is important in order to improve patient management. Few studies have investigated the role that patients' perceptions about their mental illness play in guiding coping responses and treatment seeking. The aim of the present study was to investigate how illness perceptions in high users of mental health services were related to unmet needs and treatment-seeking behaviours.

METHOD

A total of 203 high users of mental health services were interviewed using the Brief Illness Perception Questionnaire, the Camberwell Assessment of Need and the Drug Attitude Inventory, and were also asked to report the number of visits they had made to the general practitioner in the past year. District Health Board clinical staff completed the Camberwell Assessment of Need and the Global Assessment of Functioning for each user.

RESULTS

More negative perceptions about mental illness were associated with higher ratings of unmet needs by both patients and staff. Negative perceptions were also related to poorer attitudes towards medication, and lower functioning. Perceptions about the personal ability to control the illness were consistently associated with better outcomes. Patients' causal attributions could be categorized as social, psychological, biological and behavioural. More frequent visits to the general practitioner were associated with perceptions of more severe symptoms, greater concern and higher emotional responses to the illness, and psychosocial causal attributions.

CONCLUSION

Illness perceptions provide a framework to assess patients' ideas about severe mental illness and a means by which to identify maladaptive beliefs. Interventions targeted at changing these beliefs may encourage better self-management.

Comparison of single and multiple agency clients in substance abuse treatment services

BACKGROUND

Frequent and multiple service utilization among substance abusers is a well-known problem. However, little statistical evidence exists about overlapping agency populations.

METHODS

This phenomenon was studied in a clear-cut region in Belgium, based on intake information concerning all clients who addressed a drug treatment center within a 6-month period (n=1,139).

RESULTS

Multiple service utilization was rather common but not omnipresent during this particular registration period. Almost 15% of the clients were registered in more than one substance abuse treatment agency. Compared to single agency attendees, multiple agency clients appeared to be more often poly-substance abusers with a longer previous treatment history and greater problem severity.

CONCLUSION

A continuous care perspective, interagency collaboration and a common tracking and documentation system are recommended to better address the needs of this specific subgroup of substance abusers. More research is needed to clarify whether these multiple service utilization patterns are caused by client-related, agency-related or other factors.

Extreme Goal Setting and Vulnerability to Mania Among Undiagnosed Young Adults

During euthymia people with bipolar disorder and their unaffected family members accomplish more than the general population. People with bipolar disorder, or those who are at risk for it, also set higher goals in laboratory tasks than other people. The work reported here examines whether persons vulnerable to mania set elevated goals in their lives. In two studies, a measure of lifetime vulnerability to mania was related to traits bearing on incentive sensitivity, and also to endorsement of high ambitions for fame, wealth, and political influence (assessed by a new measure). Relations were weaker to ambitions for other kinds of extreme goals. The effects were independent of current symptoms of mania and depression and lifetime depression. There was also evidence that incentive sensitivity and elevated aspirations made independent contributions to variance in the measure of manic risk. Discussion focuses on the implications of high goal setting for understanding goal dysregulation and mania.

Heavy use of acute in-patient psychiatric services: the challenge to translate a utilization pattern into service provision

OBJECTIVE

There is an inequality in resource utilization among acute psychiatric in-patients. About 20-30% of them absorb 60-80% of the total resources allocated to this form of treatment. This study intends to summarize findings related to heavy in-patient service use and to illustrate them by means of utilization data for acute psychiatric wards.

METHOD

Longitudinal assessment of consecutive acute in-patients hospitalized for the first time. Analysis of individual utilization patterns by using latent class cluster analysis.

RESULTS

Four groups with different utilization patterns were found all including heavy service users. In most cases heavy service use was temporary and could only be poorly predicted.

CONCLUSION

Specific preventive interventions to contain heavy service use seem to be out of reach for the majority of high utilizing patients. However, services that have proven effective in reducing admissions to in-patient treatment and length of stay may nevertheless help to reduce heavy service use.

Heavy use of psychiatric inpatient care from the perspective of the patients affected

BACKGROUND

Patients who spend an above-average amount of time in inpatient care are termed heavy users. Up to this point, very little has been known about what drives these patients to their heavy use of inpatient treatment.

AIM

For this reason, the present study investigates the causes for frequent inpatient admissions of heavy users from the perspective of the patients affected.

METHODS

Twenty heavy users who were identified in a quantitative preliminary study were interviewed using a qualitative analysis of the contents.

RESULTS

Heavy users housed in sheltered accommodation either experienced frequent inpatient stays because of their symptomatic burden, or because of poor integration in their residences. Among the heavy users living in private residences was a subgroup that compensated for the lack of support from the private sphere with frequent hospital visits. A second subgroup turned to hospital care only during acute relapse episodes. In a third subgroup, secondary substance abuse accounted for the high demand for inpatient treatment.

CONCLUSION

Findings suggest that, using community-based psychiatric support offers tailored to the needs of the heavy user subgroups, inpatient treatment could be avoided.

Leading a horse to water: An action perspective on mental health policy

Following publication of several landmark policy documents beginning in 1999, there are unprecedented opportunities for reforming mental health care to meet the needs of persons with mental illness. In this article, the authors suggest that transforming mental health requires dramatic changes in theory as well as in policy and practice, offering action theory as a corrective for a clinical psychology that has yet to view people as active agents shaping their own lives. A participatory approach to policy development and adoption of an action-oriented model of clinical practice provide examples of the shift, which results from treating people to enhancing their access to opportunities and offering them the in vivo supports they need to pursue meaningful lives even while disabled.

Posttraumatic stress disorder: an exploratory study examining rates of trauma and PTSD and its effect on client outcomes in community mental health

BACKGROUND

Rates of trauma and Posttraumatic Stress Disorder (PTSD) were examined in order to compare the profile in clients of an Australian Public Mental Health Service with that reported in the international literature for clients with major mental illness and to explore the effect of this on client health outcomes. Potential factors contributing to increased levels of trauma/PTSD in this group of clients and the issue of causality between PTSD and subsequent mental illness was also explored.

METHODS

A convenience sample of 29 clients was screened for trauma and PTSD using the Posttraumatic Stress Diagnostic Scale (PDS) and selected outcome measures. Paired and independent samples t-test and ANOVA were applied to the data.

RESULTS

High levels of undocumented trauma and PTSD were found. Twenty clients, (74%) reported exposure to multiple traumatic events; 33.3% (9) met DSM IV diagnostic criteria for PTSD. Significant difference was found for PTSD symptomatology, severity and impairment and for client and clinician-rated scores of Quality of Life (QOL) outcomes in the PTSD group. No effect for PTSD symptomatology on the Working Alliance (WA) was found. Factors that may influence higher rates of PTSD in this group were identified and included issues associated with the population studied, the predominance of assaultive violence found, and vulnerability and risks factors associated with re-traumatisation within the social and treating environments.

CONCLUSION

A similar trauma and PTSD profile to that reported in the international literature, including greater levels of trauma and PTSD and a poorer QOL, was found in this small sample of clients. It is postulated that the increased levels of trauma/PTSD as reported for persons with major mental illness, including those found in the current study, are primarily related to the characteristics of the population that access public mainstream psychiatric services and that these factors have specific implications for service delivery, and raise issues of efficiency and effectiveness of resource use in achieving successful outcomes in public mental health services for clients with co-morbid PTSD. Further research with a more rigorous design is needed to test these preliminary findings within Australian Community Mental Health Services.

Mania and dysregulation in goal pursuit: a review

This paper reviews evidence for deficits in goal regulation in bipolar disorder. A series of authors have described mania as related to higher accomplishment, elevated achievement motivation, and ambitious goal setting. These characteristics appear to be evident outside of episodes, and to some extent, among family members of people with a history of mania. In addition, people with a history of mania demonstrate intense mood reactivity, particularly in response to success and reward. During positive moods, they appear to experience robust increases in confidence. These increases in confidence, coupled with a background of ambitious goals, are believed to promote excessive pursuit of goals. This excessive goal engagement is hypothesized to contribute to manic symptoms after an initial life success.

Factors contributing to frequent use of psychiatric inpatient services by schizophrenia patients

BACKGROUND

Although present findings about frequent users of psychiatric inpatient services vary from study to study, some potentially important predictors of frequent use were extracted. The purpose of this study was to examine the potentially contributory factors of frequent use of psychiatric inpatient services by schizophrenia patients and to test the influence single factors have in an overall model.

METHODS

A total of 307 schizophrenia patients were interviewed five times with intervals of 6 months. Data were collected about service receipt and health care costs, strength of primary diagnosis and comorbidities, as well as about patients' needs for care and satisfaction with care. Patients with three or more psychiatric admissions within a 30-month period were defined as frequent users.

RESULTS

According to this criterion, 12% of the study population were frequent users. Compared with ordinary users, these patients accounted for significantly higher costs in hospital- and community-based care. Important predictors for frequent use of psychiatric inpatient services were the number of previous hospitalizations and current scores of psychopathology. In addition, a longitudinal analysis showed the importance of social factors for the use of psychiatric inpatient care. Therefore, a number of the frequent users' multiple admissions could also be caused by social problems.

CONCLUSIONS

The mental health system should, thus, provide well-directed community-based resources, which give frequent users support to solve their social problems.

The therapeutic alliance: the key to effective patient outcome? A descriptive review of the evidence in community mental health case management

OBJECTIVE

The aim of this review was to examine the level of evidence supporting the assumed link between a positive therapeutic alliance among patients and case managers and effective outcome for patients with a mental illness who are managed in community mental health services.

METHOD

MedLine, PsychINFO and Social Sciences Index search of articles from 1986 to 2001 returned 84 articles and two texts. Inclusion criteria were the use of validated measures and relevance to psychiatry and community case management.

RESULTS

A definite correlation exists in the psychotherapy literature between the therapeutic relationship and improved outcomes, with its potential as a prognostic indicator acknowledged. Attempts to apply the concept to patients outside the field of psychotherapy have been slow, although expansion of the concept to other forms of change-inducing therapy was a current trend. Issues of definition, quantification and measurement of the relationship caused rigorous debate in the literature. Case management research demonstrating the importance of the therapeutic relationship and 'goodness-of-fit' between patients and case managers was sparse with no published Australian studies.

CONCLUSIONS

The level of evidence supporting the link between the therapeutic alliance of patients with mental illness and improved outcomes although sparse is encouraging. It indicates the potential of the alliance as a predictor of outcome for patients engaged in case management services in community mental health. Research to determine the role and effectiveness of the alliance in the patient/case manager dyad is needed to define this potential. Effectiveness of clinical practice in the case management field could be enhanced if research findings confirmed the genesis and value of the alliance in case management. Focus on relationship strategies as a clinical tool gives the clinician and service provider a potential vehicle for promoting partnerships with the seriously mentally ill person in managing their illness and optimizing their strengths in the community.

Diagnostic cost groups (DCGs) and concurrent utilization among patients with substance abuse disorders

OBJECTIVE

To assess the performance of Diagnostic Cost Groups (DCGs) in explaining variation in concurrent utilization for a defined subgroup, patients with substance abuse (SA) disorders, within the Department of Veterans Affairs (VA).

DATA SOURCES

A 60 percent random sample of veterans who used health care services during Fiscal Year (FY) 1997 was obtained from VA administrative databases. Patients with SA disorders (13.3 percent) were identified from primary and secondary ICD-9-CM diagnosis codes.

STUDY DESIGN

Concurrent risk adjustment models were fitted and tested using the DCG/HCC model. Three outcome measures were defined: (1) "service days" (the sum of a patient's inpatient and outpatient visit days), (2) mental health/substance abuse (MH/SA) service days, and (3) ambulatory provider encounters. To improve model performance, we ran three DCG/HCC models with additional indicators for patients with SA disorders.

DATA COLLECTION

To create a single file of veterans who used health care services in FY 1997, we merged records from all VA inpatient and outpatient files.

PRINCIPAL FINDINGS

Adding indicators for patients with mild/moderate SA disorders did not appreciably improve the R-squares for any of the outcome measures. When indicators were added for patients with severe SA who were in the most costly category, the explanatory ability of the models was modestly improved for all three outcomes.

CONCLUSIONS

Modifying the DCG/HCC model with additional markers for SA modestly improved homogeneity and model prediction. Because considerable variation still remained after modeling, we conclude that health care systems should evaluate "off-the-shelf" risk adjustment systems before applying them to their own populations.

Costs and characteristics of heavy inpatient service users in outer London

"Heavy users" is a new term often used to describe those who occupy a disproportionate number of psychiatric beds. In this study we identified the heaviest 10% (193) inpatient service users in one London borough over a 6 year period and compared these with a control group of 400 ordinary inpatient users. A weighting index was used to combine frequency of admission with duration. Heavy users were diagnostically and demographically similar to ordinary inpatient service users and only differed by their extensive use of services, about 3 times more than ordinary users in terms of health care costs, during the measured year. Their heavy use mainly depended on occupying hospital beds, and their use of outpatient, day patient and community services was relatively light.

Estimates of use and costs of behavioural health care: a comparison of standard and finite mixture models

Estimates of health care demand are known to depend on the empirical specification used in the analysis. In this paper, an innovative specification, the finite mixture model (FMM), is employed to estimate the utilization of and expenditures on behavioural health care. Unlike standard specifications, the FMM has the ability to distinguish between distinct classes of users of behavioural health care (e.g. the 'worried well' and the severely mentally ill). This new model is tested against standard empirical specifications using data from the National Medical Expenditure Survey. Using common risk stratifiers, estimates of utilization and costs are generated with each specification. It is found that the FMM provides a much better fit of both expenditure and utilization data than standard specifications, particularly among high intensity users that standard models have been unable to represent adequately. Furthermore, the results provide preliminary evidence that there are (at least) two distinct groups of users of behavioural health care. The empirical advantages of the FMM translate into superior estimates of mean costs and utilization that have widespread application in rate-setting exercises.

Fiscal outcomes of the closing of Central State Hospital: an analysis of the costs to state government

This study reports estimates of the preclosure and postclosure costs of mental health services for patients directly affected by the closing of Central State Hospital. The data come from state budget documents and from the billing records of the community mental health centers serving the discharged clients. On average, it cost Indiana approximately $68,347 (in 1995 dollars) to provide 12 months of state hospital care for this client cohort in fiscal year 1993. In contrast, during the first year following the closure, the average per patient cost to the state was $55,417. When clients were served exclusively in community care settings, the average annual per patient cost was $40,618. The analyses suggest that the closing reduced the costs of caring for this cohort of patients by approximately 18.9%. A significant portion of the cost savings to the state mental health budget was achieved by shifting some of the direct patient care costs to Medicaid/Medicare.

[Patterns of care in community mental health services in Lombardy]

OBJECTIVE

The analysis aims to study patterns of care of patients in contact with 5 Psychiatric Services in Lombardy. Four patterns have been identified long term-high users, non long term-high users, long term-non high users, non long term-non high users.

DESIGN

Data were provided by the regional Psychiatric Information System. The cohort of patients have been composed by 5,670 patients included in 1994 one year prevalence.

SETTING

Five Psychiatric Services (Merate, Treviglio, Crema, Desio, Castano Primo) with a total population of 610,184 inhabitants aged over 14. MAIN UTILISED MEASURES: Some sociodemographic and clinical variables have been taken into consideration for a descriptive analysis; a multinomial logistic regression model was used to identify the characteristics of patients associated with different patterns.

RESULTS

Long term-high users were 5.3%, i.e. a mean rate of 4.9/10,000 residents over 14, and absorbed 60% of resources, the absence of a partner was associated in regression analysis with this pattern. Non long term-high users were 1.2%, i.e. a mean rate of 1.1/10,000 residents over 14, and absorbed 7.8% of resources; age below 45, unemployment, absence of a partner, severe mental illness and first contact with Psychiatric Services in the period 1985-1989 were predictive variables. Long term-non high users were 23.4%, i.e. a mean rate of 21.6/10,000 residents over 14, and absorbed 18.1% of resources; age below 45, unemployment, living alone, absence of a partner, severe mental illness and first contact with Psychiatric Services before 1990 were predictive variables. Non long term-non high users were 70.1%, i.e. a mean rate of 64.8/10,000 residents over 14 and, absorbed 18.1% of resources.

CONCLUSIONS

Data show that on the whole the activity of Psychiatric Services is addressed to most serious patients, though considerable differences between Psychiatric Services utilisation may be found. This study highlights the importance of a regional Psychiatric Information System, that allows the monitoring in time and in the regional territory of patterns of care.
