Adequacy of treatment for serious mental illness in the United States

Individualization and quality improvement: two new scales to complement measurement of program fidelity

Fidelity scales have been widely used to assess program adherence to the principles of an evidence-based practice, but they do not measure important aspects of quality of care. Pragmatic scales measuring clinical quality of services are needed to complement fidelity scales measuring structural aspects of program implementation. As part of the instrumentation developed for the National Implementing Evidence-Based Practices Project, we piloted a new instrument with two 5-item quality scales, Individualization (a client-level quality scale) and Quality Improvement (an organizational-level quality scale). Pairs of independent fidelity assessors conducted fidelity reviews in 49 sites in 8 states at baseline and at four subsequent 6-month intervals over a 2-year follow-up period. The assessors followed a standardized protocol to administer these quality scales during daylong site visits; during these same visits they assessed programs on fidelity to the evidence-based practice that the site was seeking to implement. Assessors achieved acceptable interrater reliability for both Individualization and Quality Improvement. Principal components factor analysis confirmed the 2-scale structure. The two scales were modestly correlated with each other and with the evidence-based practice fidelity scales. Over the first year, Individualization and Quality Improvement improved, but showed little or no improvement during the last year of follow-up. The two newly developed scales showed adequate psychometric properties in this preliminary study, but further research is needed to assess their validity and utility in routine clinical practice.

The State Health Authority Yardstick (SHAY)

State mental health authorities have a leadership role in implementing evidence-based practices (EBPs), but few instruments are available to assess the impact of this role. We describe the development of the State Mental Health Authority Yardstick (SHAY), a behaviorally anchored instrument designed to assess state-level facilitating conditions associated with successful implementation of EBPs in community mental health centers. The SHAY assesses the SMHA role in seven domains: Planning, Financing, Training, Leadership, Policies and Regulations, Quality Improvement, and Stakeholders. Preliminary evidence from the National Evidence-Based Practices Project partially supports the construct and criterion-oriented validity of this instrument for rating state-level activities supporting or blocking the implementation of evidence-based practices.

Accumulation of major depressive episodes over time in a prospective study indicates that retrospectively assessed lifetime prevalence estimates are too low

BACKGROUND

Most epidemiologic studies concerned with Major Depressive Disorder have employed cross-sectional study designs. Assessment of lifetime prevalence in such studies depends on recall of past depressive episodes. Such studies may underestimate lifetime prevalence because of incomplete recall of past episodes (recall bias). An opportunity to evaluate this issue arises with a prospective Canadian study called the National Population Health Survey (NPHS).

METHODS

The NPHS is a longitudinal study that has followed a community sample representative of household residents since 1994. Follow-up interviews have been completed every two years and have incorporated the Composite International Diagnostic Interview short form for major depression. Data are currently available for seven such interview cycles spanning the time frame 1994 to 2006. In this study, cumulative prevalence was calculated by determining the proportion of respondents who had one or more major depressive episodes during this follow-up interval.

RESULTS

The annual prevalence of MDD ranged between 4% and 5% of the population during each assessment, consistent with existing literature. However, 19.7% of the population had at least one major depressive episode during follow-up. This included 24.2% of women and 14.2% of men. These estimates are nearly twice as high as the lifetime prevalence of major depressive episodes reported by cross-sectional studies during same time interval.

CONCLUSION

In this study, prospectively observed cumulative prevalence over a relatively brief interval of time exceeded lifetime prevalence estimates by a considerable extent. This supports the idea that lifetime prevalence estimates are vulnerable to recall bias and that existing estimates are too low for this reason.

Guideline concordance of treatment for depressive disorders in Canada

BACKGROUND

Depression is one of the most prevalent mental health problems worldwide with considerable social and economic burdens. While practice guidelines exist, their adherence is inconsistent in clinical practice.

OBJECTIVE

To provide up-to-date national estimates of the adequacy of treatment received by Canadians having suffered a major depressive disorder (MDD) and examine factors associated with this adequacy. To evaluate the impact of different definitions of guideline-concordant treatment on the results.

SUBJECTS

Data were drawn from the Canadian Community Health Survey, cycle 1.2: Mental Health and Well-Being (CCHS 1.2), a nationally representative survey conducted in 2002 and targetting persons aged 15 years or older living in private dwellings. In order to calculate the prevalence of treatment adequacy, we used a sample of 1,563 individuals meeting the criteria for MDD in the 12 months preceding the survey. A subset of 831 subjects who reported having used health services for mental health purposes at least once during that time served to identify the factors associated with treatment adequacy.

MEASUREMENTS

Four definitions of minimally adequate treatment were considered and covariates were selected according to a well-known behavioral model. The analyses consisted of prevalence estimates and logistic regression models.

RESULTS

Among selected subjects, 55% received guideline-concordant treatment according to the Canadian guidelines. Inadequacy was more prevalent in rural settings, for less complex cases, and in the general medical sector. Depending on the definition, prevalence of guideline-concordant treatment ranged between 48 and 71%, and factors associated with guideline-concordant treatment were mainly need factors and sector of care.

CONCLUSIONS

A large proportion of people with a depressive disorder do not receive minimally adequate treatment. Improved access to and quality of treatment is required, especially in primary care settings.

Major depression as a risk factor for high blood pressure: epidemiologic evidence from a national longitudinal study

OBJECTIVE

To determine whether major depression (MD) leads to an increased risk of new-onset high blood pressure diagnoses.

METHODS

The data source was the Canadian National Population Health Survey (NPHS). The NPHS included a short-form version of the Composite International Diagnostic Interview (CIDI-SF) to assess MD and collected self-report data about professionally diagnosed high blood pressure and the use of antihypertensive medications. The analysis included 12,270 respondents who did not report high blood pressure or the use of antihypertensive medications at a baseline interview conducted in 1994. Proportional hazards models were used to compare the incidence of high blood pressure in respondents with and without MD during 10 years of subsequent follow-up.

RESULTS

After adjustment for age, the risk of developing high blood pressure was elevated in those with MD. The hazard ratio was 1.6 (95% Confidence Interval = 1.2-2.1), p = .001, indicating a 60% increase in risk. Adjustment for additional covariates did not alter the association.

CONCLUSIONS

MD may be a risk factor for new-onset high blood pressure. Epidemiologic data cannot definitely confirm a causal role, and the association may be due to shared etiologic factors. However, the increased risk may warrant closer monitoring of blood pressure in people with depressive disorders.

The effect of major depression on participation in preventive health care activities

BACKGROUND

The objective of this study was to determine whether major depressive episodes (MDE) contribute to a lower rate of participation in three prevention activities: blood pressure checks, mammograms and Pap tests.

METHODS

The data source for this study was the Canadian National Population Health Survey (NPHS), a longitudinal study that started in 1994 and has subsequently re-interviewed its participants every two years. The NPHS included a short form version of the Composite International Diagnostic Interview (CIDI-SF) to assess past year MDE and also collected data on participation in preventive activities. Initially, we examined whether respondents with MDE in a particular year were less likely to participate in screening during that same year. In order to assess whether MDE negatively altered the pattern of participation, those successfully screened at the baseline interview in 1994 were identified and divided into cohorts depending on their MDE status. Proportional hazard models were used to quantify the effect of MDE on subsequent participation in screening.

RESULTS

No effect of MDE on participation in the three preventive activities was identified either in the cross-sectional or longitudinal analysis. Adjustment for a set of relevant covariates did not alter this result.

CONCLUSION

Whereas MDE might be expected to reduce the frequency of participation in screening activities, no evidence for this was found in the current analysis. Since people with MDE may contact the health system more frequently, this may offset any tendency of the illness itself to reduce participation in screening.

Differences in service utilization and barriers among Blacks, Hispanics, and Whites with drug use disorders

Background

Treatment for drug use disorders (DUD) can be effective, but only a small proportion of people with DUD seek or receive treatment. Research on racial and ethnic treatment differences and disparities remains unclear. Understanding racial and ethnic differences and disparities in drug treatment is necessary in order to develop a more effective referral system and to improve the accessibility of treatment. The purpose of the current study was to explore the role of race and ethnicity in service utilization.

Methods

Using data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), this study examined racial and ethnic differences in use of 14 types of treatment services for DUD and 27 different treatment barriers among persons who met lifetime criteria for a DUD. Multivariate logistic regression analyses were used to examine service utilization and barriers among the racial and ethnic groups, while adjusting for other sociodemographic and clinical variables.

Results and discussion

Among Blacks, Hispanics and Whites in the overall NESARC sample, approximately 10.5% met criteria for at least one lifetime drug use disorder. Approximately 16.2% of persons with a lifetime DUD received at least one type of service. Overall, this study indicated that Whites were less likely to report receiving help for drug-related problems than Blacks, Blacks used a greater number of different types of services, and no racial and ethnic differences were observed with respect to perceived barriers to drug treatment. However, by examining types of services separately, a complex picture of racial and ethnic differences emerges. Most notably, Whites were most likely to use professional services, whereas Blacks were most likely to use 12-step and clergy. The service use pattern of Hispanics most resembled that of Whites.

Conclusion

While structural barriers to accessing treatment were observed, broad-based educational programs and interventions that are appropriately targeted to racial and ethnic groups remains an important area for prevention and treatment.

Scales to evaluate quality of medication management: development and psychometric properties

This paper describes the psychometric properties of two fidelity scales created as part of the Substance Abuse and Mental Health Services Administration (SAMHSA) sponsored medication management toolkit and their metric properties when used in 26 public mental health clinics with 50 prescribers. A 23-item scale, based on chart reviews, was developed to assess whether prescribers are following good medication practices, in conjunction with a 17-item scale to assess organizational support for and evaluation of prescriber adherence to recommended medication-related practices. Fundamental gaps in routine practice, including poor documentation of medication history and infrequent monitoring of symptoms and side effects were found.

Community perceptions of mental health needs in an underserved minority neighborhood

Accurate information is needed to facilitate health equity in underserved communities. This community-based participatory study asked residents about the meaning of mental health, their perceptions of community mental health needs, barriers to accessing mental health care, and acceptability of mental health services that are integrated in primary health clinics. Forty-five primarily African-American residents from urban communities participated in focus groups. Findings revealed high prevalence of substance abuse, depression, crime, and stigma about mental illness, with multiple access barriers. Participants were receptive to mental health care integrated in primary care, if others did not know they were receiving mental health care.

Disparities in use of mental health and substance abuse services by persons with co-occurring disorders

OBJECTIVES

Individuals with co-occurring mental and substance use disorders require psychiatric and substance abuse treatments. A critical question is whether these individuals are treated for both disorders.

METHODS

This study prospectively examined 24-month service utilization patterns of 224 persons with co-occurring disorders who were recruited from crisis residential programs in the mental health treatment system (N=106) and from crisis residential detoxification programs in the substance abuse treatment system (N=118) in San Francisco. Utilization data were collected from the billing-information systems of both treatment systems. Demographic and clinical data were obtained in interviews with participants. Data were analyzed for group differences with chi square tests and logistic, linear, and zero-truncated negative binomial regression.

RESULTS

After the analyses controlled for demographic and clinical factors, participants recruited from the substance abuse treatment system were less likely than those from the mental health treatment system to obtain any mental health services, mental health day treatment, transitional residential care, case management, and other outpatient services (p<.001 for all comparisons). They were more likely to obtain crisis residential detoxification (p=.003), had more days of drug residential treatment (p=.028), but received fewer hours of outpatient services (p=.012).

CONCLUSIONS

There were disparities in patterns of service utilization, although there were no significant diagnostic differences between the two groups. These findings should be valuable in considering systems development and modification. Furthermore, they can contribute to research about factors that underlie results. Study replications should be conducted to assess the robustness of these findings in other locales.

The Pediatric Obsessive-Compulsive Disorder Treatment Study II: rationale, design and methods

This paper presents the rationale, design, and methods of the Pediatric Obsessive-Compulsive Disorder Treatment Study II (POTS II), which investigates two different cognitive-behavior therapy (CBT) augmentation approaches in children and adolescents who have experienced a partial response to pharmacotherapy with a serotonin reuptake inhibitor for OCD. The two CBT approaches test a "single doctor" versus "dual doctor" model of service delivery. A specific goal was to develop and test an easily disseminated protocol whereby child psychiatrists would provide instructions in core CBT procedures recommended for pediatric OCD (e.g., hierarchy development, in vivo exposure homework) during routine medical management of OCD (I-CBT). The conventional "dual doctor" CBT protocol consists of 14 visits over 12 weeks involving: (1) psychoeducation, (2), cognitive training, (3) mapping OCD, and (4) exposure with response prevention (EX/RP). I-CBT is a 7-session version of CBT that does not include imaginal exposure or therapist-assisted EX/RP. In this study, we compared 12 weeks of medication management (MM) provided by a study psychiatrist (MM only) with two types of CBT augmentation: (1) the dual doctor model (MM+CBT); and (2) the single doctor model (MM+I-CBT). The design balanced elements of an efficacy study (e.g., random assignment, independent ratings) with effectiveness research aims (e.g., differences in specific SRI medications, dosages, treatment providers). The study is wrapping up recruitment of 140 youth ages 7-17 with a primary diagnosis of OCD. Independent evaluators (IEs) rated participants at weeks 0,4,8, and 12 during acute treatment and at 3,6, and 12 month follow-up visits.

Allergies and major depression: a longitudinal community study

Background

Cross-sectional studies have reported associations between allergies and major depression but in the absence of longitudinal data, the implications of this association remain unclear. Our goal was to examine this association from a longitudinal perspective.

Methods

The data source was the Canadian National Population Health Survey (NPHS). This study included a short form version of the Composite International Diagnostic Interview (CIDI-SF) to assess major depression and also included self report items for professionally diagnosed allergies of two types: non-food allergies and food allergies. A longitudinal cohort was followed between 1994 and 2002. Proportional hazards models for grouped time data were used to estimate unadjusted and adjusted hazard ratios.

Results

A slightly increased incidence of non-food allergies in respondents with major depression was observed: adjusted hazard ratio 1.2 (95% 1.0 – 1.5, p = 0.046). Some evidence for an increased incidence of major depression in association with non-food allergies was found in unadjusted analyses, but the association did not persist after multivariate adjustment. Food allergies were not associated with major depression incidence, nor was major depression associated with an increased incidence of food allergies.

Conclusion

Findings from the present study support the idea that major depression is associated with an increased risk of developing non-food allergies. An effect in the opposite direction could not be confirmed. The observed effect may be due to shared genetic factors, epigenetic factors, or immunological changes that occur during depression.

Bridging bench and practice: translational research for schizophrenia and other psychotic disorders

Translational research is urgently needed to turn basic scientific discoveries into widespread health gains and nowhere are these needs greater than in conditions such as schizophrenia and other psychotic disorders. In this article, we discuss one type of translational research--called T1--which is needed to take advantage of developments in the basic neurosciences and translate them into more efficacious diagnostic, preventive, and therapeutic interventions. However, ensuring that interventions from T1 research actually benefit patients will require a second form of translational research--called T2--to turn innovations into everyday clinical practice and health decision-making. Recent examples of T1 and T2 research in schizophrenia and other psychotic disorders as well as strategies for better linking T1 and T2 research agendas are covered.

Shared decision making in antipsychotic management

The similar efficacies of currently available antipsychotic medications (other than clozapine) make them appropriate for preference-sensitive care; therefore, prescribing these medications is amenable to shared decision-making. In this conceptual article, we describe the current state of antipsychotic prescribing based on a review of the literature from recent landmark studies and updated prescribing guidelines. Recent literature and guidelines on schizophrenia treatment in the United States do not reveal strong endorsement of the idea of shared decision-making. We suggest methods for incorporating shared decision-making into antipsychotic prescribing in the future, with an emphasis on the use of information technology.

National Practice Guidelines for Mental Health Care

Mental disorders are the leading cause of disability worldwide, according to the World Health Organization (WHO, 1996). In a report on health indicators of premature death and disability, the World Bank concluded that mental health problems account for 8.1% of the global burden of disease (GBD). Industrialized nations have taken different approaches in applying innovations to mental health care and mental health care policy. This paper uses the K. McInnis-Dittrich model of policy analysis (Ginsberg, 1994) to analyze the approaches of the United Kingdom (U.K.) and the United States (U.S.) to mental health treatment, specifically examining the effects of the U.K.'s national practice guidelines and the U.S.'s lack of similar guidelines. Recommendations for changes in current U.S. mental health policy are presented.

Integrated specialty mental health care among older minorities improves access but not outcomes: results of the PRISMe study

OBJECTIVE

In this secondary data analysis of Primary Care Research in Substance Abuse and Mental Health for the Elderly (PRIMSe) study, we hypothesized that older minorities who receive mental health services integrated in primary care settings would have greater service use and better mental health outcomes than older minorities referred to community services.

METHOD

We identified 2,022 (48% minorities) primary care patients 65 years and older, who met study inclusion criteria and had either alcohol misuse, depression, and/or anxiety. They were randomized to receive treatment for these disorders in the primary care clinic or to a brokerage case management model that linked patients to community-based services. Service use and clinical outcomes were collected at baseline, three months and six months post randomization on all participants.

RESULTS

Access to and participation in mental health /substance abuse services was greater in the integrated model than in referral; there were no treatment by ethnicity effects. There were no treatment effects for any of the clinical outcomes; Whites and older minorities in both integrated and referral groups failed to show clinically significant improvement in symptoms and physical functioning at 6 months.

CONCLUSIONS

While providing services in primary care results in better access to and use of these services, accessing these services is not enough for assuring adequate clinical outcomes.

Integrating health and social care in community mental health teams in the UK: a study of assessments and eligibility criteria in England

The purpose of this cross-sectional survey was to examine the relationship between assessments and eligibility decisions made by health and social care staff in multidisciplinary community teams in England. The data were collected between December 2004 and August 2005. The study was a replication of a study that took place in the same eight locations in England before the modernization of health and social care by the present government. Four hundred and thirteen care coordinators responded from 71 teams to produce a total of 1481 clients. Sixty per cent (n = 884) of the sample of clients were categorised as having a psychotic illness compared to 63% in 1997 to 1998. Fair Access to Care Services (FACS) criteria determine access to social care services, and the Care Programme Approach (CPA) determines the level of mental health services provided. There was a close but an incomplete association between FACS and CPA judgements (kappa = 0.37; 95% confidence interval 0.31-0.43). Compared to the standardised Matching Resources to Care version 2 indication of complex needs, social workers' judgements were the most closely aligned to FACS judgements (F = 5.80; d.f. = 2 and 1203; P < 0.01). This raises the question of the need for training for health professionals in order to make decisions about social assessment and eligibility determination.

Predictors of competitive employment among patients with schizophrenia

PURPOSE OF REVIEW

Recently published studies examining predictors of competitive employment for patients with schizophrenia are reviewed.

RECENT FINDINGS

Researchers continue to examine predictors of employment among three types of variables: patient characteristics, environmental factors, and interventions. Provision of supported employment is the strongest predictor of competitive employment in this population, while patient predictors continue to show modest associations with outcomes. Environmental factors, including societal and cultural influence, local economy, labor laws, disability policies, and governmental regulations, are presumed to have major influences on employment, but these factors have been little studied.

SUMMARY

Given the strong and consistent evidence base for the effectiveness of supported employment in helping individuals with schizophrenia achieve competitive employment, mental health planners should make access to this practice a high priority. Barriers to implementation of supported employment, including finance, organization, integration, training, and supervision, need to be systematically addressed. The field currently lacks an adequate understanding of the role of societal, cultural, and regulatory factors in facilitating and hindering employment outcomes; such research is much needed.

Cost of medical detoxification among drug and alcohol users in a private Texas hospital

Purpose

The purpose of this paper is to estimate the costs of medical detoxification among patients with alcohol and substance abuse disorders.

Design/methodology/approach

The study data was drawn from a medical detoxification program in a community hospital in Texas. Secondary data analysis of 1337 cases from three years was reviewed. Age, gender, race, alcohol, cocaine, cannabis, amphetamines, sedatives, opioids, financial classification, cost, length of stay (LOS) and cost by LOS were analyzed using Kruskal‐Wallis test and Mann‐Whitney U‐test.

Findings

The sample comprised of 42.8 percent women and 57.2 percent males. The mean cost and cost by LOS was highest for cocaine ($2560.1 and $1,044, P<0.01), while opioid and cannabis ($815.5, p<0.01; $823.7, p<0.01) had significantly higher values than the rest. In each individual drug detoxification class, except for amphetamines, the mean and median LOS has been reported to be less among the uninsured category compared to privately insured subjects. In addition, the cost by LOS was also found to be higher in the uninsured group compared to those with private insurance. Subjects who were uninsured and abused alcohol had higher median costs of detoxification (P<0.01) by LOS.

Research limitations/implications

Further in‐depth analysis for confounding and interactions between variables is warranted.

Originality/value

This research provides an estimation of LOS of a medical detoxification program by financial class in the USA and illustrates that early discharge of uninsured and Medicaid patients can be attributable to aggressive case management practices, interrupting the normal course of care.

The impact of psychoticism on perceived hassles, depression, hostility, and hopelessness in non-psychiatric African Americans

Psychotic symptoms are distributed along a continuum that extends from normality to diagnosable psychotic disorders and the presence of psychoticism among individuals in the general population may lead to morbidity and social impairment. This study examined a model in which psychoticism leads to several important psychological consequences. The analysis included 134 African Americans with no psychiatric history who were being seen in medical walk-in clinics for non-emergency medical problems. Psychoticism, perceived hassles, depression, hostility, and hopelessness were measured. The Linear Structural Relations Program (LISREL) was used to test the fit of the data to the proposed model, a trimmed hierarchical version, and two alternative models. The data supported a model in which psychoticism has substantial effects on several important characteristics: perceived daily hassles, depression, and hostility. Depression mediated the association between psychoticism and hopelessness. Goodness-of-fit indices for a final trimmed model that eliminated one path from the initial postulated model revealed good fit to the data, and the two alternative models were found not to fit the data. Like psychosis itself, psychoticism appears to cause meaningful dysfunction even among non-psychiatric individuals from the general population. Additional research is needed to further characterize the detrimental effects of psychoticism or self-reported psychotic symptoms in the general, non-psychiatric population.

Quality improvement in psychiatry: why measures matter

Increasing attention has been directed in healthcare today to the importance of performance measurement, (i.e., the implementation of measurable methods to demonstrate that practitioners are engaged in high-quality, evidence-based medicine). Many medical specialties, as well as many state medical licensing boards, now require that candidates submit performance measurement data, to be eligible for maintenance of board certification or medical licensure. National organizations such as the National Quality Forum and the Physicians Consortium for Performance Improvement of the American Medical Association are active collaborators with federal, state, and medical specialty initiatives to improve healthcare. These developing efforts are summarized here, with a specific focus on the status of these efforts in the field of psychiatry.

Cognitive-Behavioral Treatment for Panic Disorder With Agoraphobia

A randomized, controlled trial was conducted to examine the cost-effectiveness of cognitive-behavioral treatment (CBT) for panic disorder with agoraphobia. A total of 100 participants were randomly assigned to standard ( n = 33), group ( n = 35), and brief ( n = 32) treatment conditions. Results show significant clinical and statistical improvement on standard symptom measures and quality of life from baseline to posttreatment and 3-month follow-up, with no significant differences between treatment conditions. Compared with standard CBT, brief and group CBT incurred lower treatment costs and had a superior cost-effectiveness ratio, suggesting the potential of these alternative treatment conditions in increasing access to effective treatment.

Organizational change to transfer knowledge and improve quality and outcomes of care for patients with severe mental illness: a systematic overview of reviews

OBJECTIVE

To provide a comprehensive overview of the research on organizational changes aimed at improving health care for patients with severe mental illness and to learn lessons for mental health practice from the results.

METHOD

We searched for systematic literature reviews published in English during 2000 to 2007 in PubMed, PsycINFO, CINAHL, EMBASE, and the Cochrane Central Register of Systematic Reviews. Three reviewers independently selected and assessed the studies' quality. Studies involving changes of who delivers health care, how care is organized, or where care is delivered were included. We categorized the studies using an existing taxonomy of 6 broad categories of strategies for organizational change.

RESULTS

A total of 21 reviews were included. Among these, 17 had reasonably good methodological quality, Almost all reviews included or intended to include randomized controlled trials (RCTs), 6 reviews did not identify studies that met eligibility criteria. Multidisciplinary teams and integrated care models had been reviewed most frequently (a total of 15 reviews). In most studies, these types of changes showed better outcomes in terms of symptom severity, functioning, employment, and housing, compared with conventional services. Different results were found on cost savings. Other types of organizational changes, such as changing professional roles or introducing quality management or knowledge management, were much less frequently reviewed. Very few reviews looked at effects of organizational changes on professional performance.

CONCLUSIONS

There is a fairly large body of evidence of the positive impact of multidisciplinary teams and integrated care changes on symptom severity, functioning, employment, and housing of people with severe mental illness, compared with conventional services. Other strategies, such as changes in professional roles, quality or knowledge management, have either not been the subject of systematic reviews or have not been evaluated in RCTs. There is still a lack of insight in the so-called black box of change processes and the impact of change on professional performance.

Use of health services for major depressive and anxiety disorders in Finland

Factors associated with people suffering from major depressive disorder (MDD) or anxiety disorders seeking or receiving treatment are not well known. In the Health 2000 Study, a representative sample (n=6005) of Finland's general adult (> or =30 years) population was interviewed with the M-CIDI for mental disorders and health service use for mental problems during the last 12 months. Predictors for service use among those with DSM-IV MDD (n=298) or anxiety disorders (n=242) were assessed. Of subjects with MDD, anxiety disorders, or both, 34%, 36%, and 59% used health services, respectively. Greater severity and perceived disability, psychiatric comorbidity, and living alone predicted health care use for MDD subjects, and greater perceived disability, psychiatric comorbidity, younger age, and parent's psychiatric problems for anxiety disorder subjects. The use of specialist-level mental health services was predicted by psychiatric comorbidity, but not characteristics of the disorders per se. Perceived disability and comorbidity are factors influencing the use of mental health services by both anxiety disorder and MDD subjects. However, still only approximately one-half of those suffering from even severe and comorbid disorders use health services for them.

The prevalence and correlates of workplace depression in the national comorbidity survey replication

OBJECTIVE

To review evidence on the workplace prevalence and correlates of major depressive episodes, with a particular focus on the National Comorbidity Survey Replication, the most recent national survey to focus on these issues.

METHOD

Nationally representative survey of Diagnostic and Statistical Manual, 4th Revision Mental Disorders.

RESULTS

A total of 6.4% of employed National Comorbidity Survey Replication respondents had 12-month major depressive disorder. An additional 1.1% had major depressive episodes due to bipolar disorder or mania-hypomania. Only about half of depressed workers received treatment. Fewer than half of treated workers received care consistent with published treatment guidelines.

CONCLUSIONS

Depression disease management programs can have a positive return-on-investment from the employer perspective, but only when they are based on best practices. Given the generally low depression treatment quality documented here, treatment quality guarantees are needed before expanding workplace depression screening, outreach, and treatment programs.

The descriptive epidemiology of commonly occurring mental disorders in the United States

Data are reviewed on the descriptive epidemiology of commonly occurring DSM-IV mental disorders in the United States. These disorders are highly prevalent: Roughly half the population meets criteria for one or more such disorders in their lifetimes, and roughly one fourth of the population meets criteria in any given year. Most people with a history of mental disorder had first onsets in childhood or adolescence. Later onsets typically involve comorbid disorders. Some anxiety disorders (phobias, separation anxiety disorder) and impulse-control disorders have the earliest age of onset distributions. Other anxiety disorders (panic disorder, generalized anxiety disorder, post-traumatic stress disorder), mood disorders, and substance disorders typically have later ages of onset. Given that most seriously impairing and persistent adult mental disorders are associated with child-adolescent onsets and high comorbidity, increased efforts are needed to study the public health implications of early detection and treatment of initially mild and currently largely untreated child-adolescent disorders.

Financing mental health and substance use disorder care within physical health: a look to the future

After sharing several case examples of health care for patients who have mental health/substance use disorders (MH/SUDs) in the current health care environment, this article describes the advantages that would occur if assessment and treatment of MH/SUDs became a clinical, administrative, and financial part of physical health with common provider networks, the ability to combine service locations (integrated clinics and inpatient units), similar coding and billing procedures, and a single funding pool. Because transition to such a system is complicated, the article then describes several process changes that would be required for integrated service delivery to take place.

Evaluation and characterization of generalized anxiety and depression in patients with primary brain tumors

To determine clinical and sociodemographic factors that are associated with major neuropsychiatric illnesses among brain tumor patients, we administered a modified version of the Brief Patient Health Questionnaire and a demographic data form to 363 adult neuro-oncology patients. Responses were analyzed to assess for associations between demographic variables, clinical variables, and symptoms consistent with diagnoses of generalized anxiety disorder and/or depression. Multivariate logistic regression analyses showed that female gender was associated with the presence of symptoms of anxiety, depression, and combined anxiety and depression. Lower WHO tumor grade classifications, lower education level, and a history of psychiatric illness also emerged as important predictors of symptoms consistent with anxiety and/or depression. Marital status and presence of past/current medical illness trended toward being significantly associated with depression alone. Patient use of psychiatric medication was not associated with any study variables. Results of the present study suggest several hypotheses to test with neuro-oncology patients in further longitudinal analyses, which would benefit from the inclusion of a wider range of neuropsychiatric symptoms in conjunction with neurocognitive and functional impairment variables.

Issues in the dissemination of cognitive-behavior therapy

In the past 40 years, cognitive-behavior therapy (CBT) has emerged as the initial treatment of choice for patients with mild to moderate depression, anxiety disorders and other problems. In this paper, we discuss issues related to the dissemination and implementation of CBT in various practice settings as well as the use of manuals, computers, the telephone, and the Internet to aid dissemination and implementation. We review key aspects of CBT dissemination, such as the reach of CBT, models of dissemination, and obstacles and barriers to dissemination including patient interest, therapist training and research priorities. The effectiveness of manualized programs is considered, as well as the increasing sophistication of computer-assisted therapy. Stepped-care approaches are discussed as a viable solution to some of these barriers. We provide two examples of successful CBT dissemination, the Staying Free program, a smoking cessation program for inpatients, and the Improving Access to Psychological Therapies program in Britain, which aims to improve access to psychological therapy. We argue that two critical factors will determine the success of implementation of CBT in this century: 1) mandated outcomes and 2) leadership.

Causes of schizophrenia reported by urban African American lay community members

Although mental health professionals' "etiologic beliefs" concerning schizophrenia have evolved in accordance with diathesis-stress and neurodevelopmental models, little is known about etiologic attributions in nonclinical general population samples in the United States. Yet, course and outcome for people with the illness may be indirectly influenced by beliefs about causes in the larger community. Because of very limited research in this area, especially among African Americans in particular, this descriptive study investigated the causes of schizophrenia reported by 127 urban African Americans from the general population. The aim of this study was to assess the most commonly reported causes of schizophrenia, as well as the frequency of endorsing items from a list of 30 factors, some of which are congruent with current psychiatric conceptualizations of schizophrenia, whereas others are not. Results of this report complement previously reported findings from the same setting involving family members of patients with schizophrenia [Esterberg ML, Compton MT. Causes of schizophrenia reported by family members of urban African American hospitalized patients with schizophrenia. Compr Psychiatry 2006;47:221-226]. The 5 most commonly reported causes were disturbance of brain biochemistry (49.6%), drug/alcohol abuse (42.5%), hereditary factors (40.9%), brain injury (40.2%), and avoidance of problems in life (37.8%). The mean number of likely or very likely causes endorsed by participants was 7.5 +/- 5.7. Some 47.9% reported one or more esoteric factors as a cause. Of the 6 esoteric factors, possession by evil spirits (28.3%), radiation (20.2%), and punishment by God (19.7%) were most common. Esoteric causes were more commonly chosen by male participants, those with 12 years of education or less, and participants who reported never having known someone with schizophrenia. Future research should seek to better understand how esoteric beliefs about causation affect attitudes toward people with mental illnesses and acceptance of mental health treatment by those individuals. Beliefs about debunked personality, societal, family, and esoteric causes in this nonclinical sample indicate the need for improved psychoeducation of the community at large.

Frequency and adequacy of depression treatment in a Canadian population sample

OBJECTIVE

Population-based data about depression treatment are largely restricted to estimates of the frequency of antidepressant (AD) use. Such frequencies are difficult to interpret in the absence of information about dosages, reasons for taking the medications, and participation in nonpharmacologic treatment. The objective of this study was to describe the pattern of treatment for major depression (MD) in Alberta.

METHOD

Telephone survey methods were employed. Random digit dialing was used to select a sample of 3345 household residents aged 18 to 64 years in Alberta. A computer-assisted telephone interview that included the Mini Neuropsychiatric Diagnostic Interview and questions about pharmacotherapy and psychotherapy was administered. Estimates were weighted for design features and population demographics.

RESULTS

The point prevalence of MD was 4.4% (95% confidence interval [CI], 3.4% to 5.5%), and the overall prevalence of current AD use was 7.4% (95% CI, 6.2% to 8.6%). The ADs taken most commonly, serotonin-specific reuptake inhibitors, were taken at therapeutic dosages 87.4% of the time. Most (80.7%) of those taking ADs reported taking them for more than 1 year. The frequency of receiving counselling, psychotherapy, or talk therapy was 3.9% overall and 14.3% in respondents with MD. However, most of these subjects were unable to name the type of counselling they were receiving.

CONCLUSIONS

When compared with previous estimates, these results suggest continued progress in the delivery of evidence-based care to the population. There is room for additional improvement, especially in the provision of nonpharmacologic treatment.

Understanding mental health treatment in persons without mental diagnoses: results from the National Comorbidity Survey Replication

CONTEXT

Epidemiologic surveys have consistently found that approximately half of respondents who obtained treatment for mental or substance use disorders in the year before interview did not meet the criteria for any of the disorders assessed in the survey. Concerns have been raised that this pattern might represent evidence of misallocation of treatment resources.

OBJECTIVE

To examine patterns and correlates of 12-month treatment of mental health or substance use problems among people who do not have a 12-month DSM-IV disorder.

DESIGN AND SETTING

Data are from the National Comorbidity Survey Replication, a nationally representative face-to-face US household survey performed between February 5, 2001, and April 7, 2003, that assessed DSM-IV disorders using a fully structured diagnostic interview, the World Health Organization Composite International Diagnostic Interview (CIDI).

PARTICIPANTS

A total of 5692 English-speaking respondents 18 years and older.

MAIN OUTCOME MEASURES

Patterns of 12-month service use among respondents without any 12-month DSM-IV CIDI disorders.

RESULTS

Of respondents who used 12-month services, 61.2% had a 12-month DSM-IV CIDI diagnosis, 21.1% had a lifetime but not a 12-month diagnosis, and 9.7% had some other indicator of possible need for treatment (subthreshold 12-month disorder, serious 12-month stressor, or lifetime hospitalization). The remaining 8.0% of service users accounted for only 5.6% of all services and even lower proportions of specialty (1.9%-2.4%) and general medical (3.7%) visits compared with higher proportions of human services (18.9%) and complementary and alternative medicine (7.6%) visits. Only 26.5% of the services provided to the 8.0% of presumably low-need patients were delivered in the mental health specialty or general medical sectors.

CONCLUSIONS

Most services provided for emotional or substance use problems in the United States go to people with a 12-month diagnosis or other indicators of need. Patients who lack these indicators of need receive care largely outside the formal health care system.

Telephone screening, outreach, and care management for depressed workers and impact on clinical and work productivity outcomes: a randomized controlled trial

CONTEXT

Although guideline-concordant depression treatment is clearly effective, treatment often falls short of evidence-based recommendations. Organized depression care programs significantly improve treatment quality, but employer purchasers have been slow to adopt these programs based on lack of evidence for cost-effectiveness from their perspective.

OBJECTIVE

To evaluate the effects of a depression outreach-treatment program on workplace outcomes, a concern to employers.

DESIGN, SETTING, AND PARTICIPANTS

A randomized controlled trial involving 604 employees covered by a managed behavioral health plan were identified in a 2-stage screening process as having significant depression. Patient treatment allocation was concealed and assessment of depression severity and work performance at months 6 and 12 was blinded. Employees with lifetime bipolar disorder, substance disorder, recent mental health specialty care, or suicidality were excluded.

INTERVENTION

A telephonic outreach and care management program encouraged workers to enter outpatient treatment (psychotherapy and/or antidepressant medication), monitored treatment quality continuity, and attempted to improve treatment by giving recommendations to providers. Participants reluctant to enter treatment were offered a structured telephone cognitive behavioral psychotherapy.

MAIN OUTCOME MEASURES

Depression severity (Quick Inventory of Depressive Symptomatology, QIDS) and work performance (World Health Organization Health and Productivity Questionnaire [HPQ], a validated self-report instrument assessing job retention, time missed from work, work performance, and critical workplace incidents).

RESULTS

Combining data across 6- and 12-month assessments, the intervention group had significantly lower QIDS self-report scores (relative odds of recovery, 1.4; 95% confidence interval, 1.1-2.0; P = .009), significantly higher job retention (relative odds, 1.7; 95% confidence interval, 1.1-3.3; P = .02), and significantly more hours worked among the intervention (beta=2.0; P=.02; equivalent to an annualized effect of 2 weeks of work) than the usual care groups that were employed.

CONCLUSIONS

A systematic program to identify depression and promote effective treatment significantly improves not only clinical outcomes but also workplace outcomes. The financial value of the latter to employers in terms of recovered hiring, training, and salary costs suggests that many employers would experience a positive return on investment from outreach and enhanced treatment of depressed workers.

Prevalence, comorbidity, and service utilization for mood disorders in the United States at the beginning of the twenty-first century

The results of recent community epidemiological research are reviewed, documenting that major depressive disorder (MDD) is a highly prevalent, persistent, and often seriously impairing disorder, and that bipolar disorder (BPD) is less prevalent but more persistent and more impairing than MDD. The higher persistence and severity of BPD results in a substantial proportion of all seriously impairing depressive episodes being due to threshold or subthreshold BPD rather than to MDD. Although the percentage of people with mood disorders in treatment has increased substantially since the early 1990s, a majority of cases remain either untreated or undertreated. An especially serious concern is the misdiagnosis of depressive episodes due to BPD as due to MDD because the majority of depression treatment involves medication provided by primary care doctors in the absence of psychotherapy. The article closes with a discussion of future directions for research.

Recent developments in psychosocial treatments for schizophrenic patients

Pessimistic views regarding the course and outcome of schizophrenia have been replaced by an emphasis on recovery. The concept of recovery emphasizes the need to provide access to treatments and services that are effective in both decreasing manifestations of the disorder and in assisting individuals to lead maximally productive and personally meaningful lives. To this end, the schizophrenia Patient Outcomes Research Team (PORT) published an updated consensus list of evidence-based practices that includes 14 recommendations, six of which describe psychosocial treatments (family interventions, supported employment, assertive community treatment, skills training, cognitive therapy and token economy programs). This paper reviews the schizophrenia PORT committee recommendations for psychosocial evidence-based practices, and discusses future needs and potential confounds that can have an impact on the effectiveness of these approaches. Among these potential confounds, the heterogeneity of individuals diagnosed with schizophrenia, variations in quality and integrity of implementation and the degree to which services listed are truly accessible and available as needed are paramount. The PORT psychosocial recommendations are an excellent foundation in the process of identifying evidence-based practices that can foster social recovery; they are not a comprehensive list. More innovation and research on psychosocial therapies remains to be accomplished in order to improve the chances for social recovery of patients diagnosed with schizophrenia.

Discontinuation of antidepressant medication among Latinos in the USA

Despite recent growth in the variety of antidepressant medications available, many patients discontinue medication prematurely for reasons such as nonresponse, side effects, stigma, and miscommunication. Some analysts have suggested that Latinos may have higher antidepressant discontinuation rates than other US residents. This paper examines Latino antidepressant discontinuation, using data from a national probability survey of Latinos in the USA. In this sample, 8% of Latinos had taken an antidepressant in the preceding 12 months. Among those users, 33.3% had discontinued taking antidepressants at the time of interview, and 18.9% had done so without prior input from their physician. Even controlling for clinical and other variables, patients who reported good or excellent English proficiency were less likely to stop at all. Patients were also less likely to stop if they were older, married, had public or private insurance, or had made eight or more visits to a nonmedical therapist.

Knocking at the wrong door: insured workers' inadequate psychiatric care and workers' compensation claims

OBJECTIVE

To describe the prevalence of inadequately evaluated and treated psychopathology among insured workers making workers' compensation claims for psychiatric disability whose cases were reviewed by one forensic psychiatrist. To assess the relationship of inadequate evaluation and treatment to the outcomes of these workers' compensation claims.

METHODS

Records of a series of 185 workers' compensation cases reviewed in 1998 and 1999 by a California forensic psychiatrist were abstracted. Patient factors (gender, Axis II pathology, psychosocial circumstances, substance abuse), case factors (psychiatric injury secondary to physical injury, or secondary to psychological stresses), type of provider (mental health, or other), adequacy of evaluation and treatment, forensic psychiatrist's recommendation, and claim outcome were categorized. The relationships between case characteristics, adequacy of care, and claim outcome were described.

RESULTS

22% of cases had adequate evaluation, 48% superficial, and 30% had no evaluation. 11% had adequate treatment, 67% superficial, and 22% had no treatment. Compared to claims for psychiatric disability related to a physical injury, claims related to psychosocial stresses more often had superficial diagnostic evaluations and treatments. Those with superficial treatment were less likely to have their claim granted (19.3%) than those with no treatment (47.5%) or those with adequate treatment (36.8%). Success of claim was not related to provider type.

CONCLUSIONS

The majority of the studied workers with employer-provided health insurance who sought workers' compensation for disability due to mental illness did so inappropriately, in that the workplace did not cause the psychopathology. Their seeking workers' compensation was plausibly due to the observed inadequate evaluation and treatment available through their employer-provided health insurance. The adequacy of their care influenced the likelihood their claim would be granted. The relations observed here merit further research to establish their generality and to determine their causes.

Disparities in access to healthcare: the case of a drug and alcohol abuse detoxification treatment program among minority groups in a Texas hospital

The authors analyzed ethnic/racial disparities in healthcare access and length of stay from a defined population of individuals seeking medical detoxification services at a hospital in Texas. Results indicated Blacks were more likely to be insured compared with Whites, mostly by public insurance, but this did not hold for Hispanics, who were about three times more likely to be uninsured compared with Blacks. In addition, the authors observed lower median of length of stay in the Medicaid category among Hispanics. These results can be explained by aggressive case management, sociocultural barriers, or discriminatory practices, both intentional and unintentional.

Population level of unmet need for mental healthcare in Europe

BACKGROUND

The high prevalence of mental disorders has fuelled controversy about the need for mental health services.

AIMS

To estimate unmet need for mental healthcare at the population level in Europe.

METHOD

As part of the European Study of Epidemiology of Mental Disorders (ESEMeD) project, a cross-sectional survey was conducted of representative samples of the adult general population of Belgium, France, Germany, Italy, The Netherlands and Spain (n=8796). Mental disorders were assessed with the Composite International Diagnostic Interview 3.0. Individuals with a 12-month mental disorder that was disabling or that had led to use of services in the previous 12 months were considered in need of care.

RESULTS

About six per cent of the sample was defined as being in need of mental healthcare. Nearly half (48%) of these participants reported no formal healthcare use. In contrast, only 8% of the people with diabetes had reported no use of services for their physical condition. In total, 3.1% of the adult population had an unmet need for mental healthcare. About 13% of visits to formal health services were made by individuals without any mental morbidity.

CONCLUSIONS

There is a high unmet need for mental care in Europe, which may not be eliminated simply by reallocating existing healthcare resources.

Treatment adequacy of anxiety and depressive disorders: primary versus specialised care in Spain

BACKGROUND

Literature suggests that a high proportion of the population with mental disorders remains either untreated or poorly treated. This study aimed to describe the adequacy of treatment for Anxiety and Depressive disorders in Spain, how this differs between providers (primary versus specialised care) and which factors are associated with appropriate care.

METHOD

Data were derived from the Spanish sample (N=5473) of the European Study of the Epidemiology of Mental Disorders (ESEMeD), a cross sectional study in a representative sample of adults. The subsample analyzed was composed by the 133 subjects with a mental disorder in the year prior to the interview who received treatment. Treatment adequacy was evaluated in two different ways: (1) considering definitions of minimally adequate treatment evidence based guidelines and criteria used in other epidemiological studies; (2) considering experts rating of treatment appropriateness based on the information contained in the case vignettes created from the CIDI answers. Generalised Estimating Equation (GEE) models and simple logistic regression were conducted to assess the correlates of adequate treatment.

RESULTS

Similar proportions of patients in specialty and general medical treatment received a minimally adequate treatment (31.8% and 30.5%, respectively). Associated factors to appropriateness were living in a large city, having a high educational level, and having a good self rated health state.

LIMITATIONS

Treatment adequacy was based on simple information and criteria.

CONCLUSIONS

Only one third of the mental health treatment in Spain met minimal adequacy criteria. More research is needed in order to find out reasons for these low rates.

Detection of co-occurring mental illness among adult patients in the New Jersey substance abuse treatment system

OBJECTIVES

We assessed the detection of mental illness in an adult population of substance abuse patients and the rate of referral for mental health treatment.

METHODS

We obtained combined administrative records from 1994 to 1997 provided by the New Jersey substance abuse and mental health systems and estimated detection and referral rates of patients with co-occurring disorders (n = 47,379). Mental illness was considered detected if a diagnosis was in the record and considered undetected if a diagnosis was not in the record but the patient was seen in both treatment systems within the same 12-month period. Predictors of detection and referral were identified.

RESULTS

The detection rate of co-occurring mental illness was 21.9% (n=10364); 57.9% (n=6001) of these individuals were referred for mental health treatment. Methadone maintenance clinics had the lowest detection rate but the highest referral rate. Male, Hispanic, and African American patients, as well as those who used heroin or were in the criminal justice system, had a higher risk of mental illness not being detected. Once detected, African American patients, heroin users, and patients in the criminal justice system were less likely to be referred for treatment.

CONCLUSIONS

There is a need to improve the detection of mental illness among substance abuse patients and to provide integrated treatment.

Enhancing validity in co-occurring disorders treatment research

Despite the high prevalence of co-occurring mental health and substance-use disorders, there has been a relative lack of treatment research with this population, and the existing research often has limited validity. This article explores some of the barriers to the conduct of research on promising interventions for substance-abuse treatment for people with co-occurring disorders, using the concepts of external and ecological validity to make recommendations for future investigation. The central recommendation is to move rapidly from efficacy studies to more credible and valid effectiveness studies, in order to facilitate the adoption of evidence-based interventions in routine practice settings.
