A community study of depression treatment and employment earnings

The effect of "failed" community mental health centers on non-white mortality

The Community Mental Health Act of 1963 established Community Mental Health Centers (CMHCs) across the country with the goal of providing continuous, comprehensive, community-oriented care to people suffering from mental illness. Despite this program being considered a failure by most contemporary accounts, the World Health Organization advocates for a transition from the institutionalization of the mentally ill to a system of community-centered care. In this paper, we construct a novel dataset documenting the rollout of CMHCs from 1971 to 1981 to identify the effect of establishing a CMHC on county level mortality rates, focusing on causes of death related to mental illness. Though we find little evidence that access to a CMHC impacted mortality rates in the white population, we find large and robust effects for the non-white population, with CMHCs reducing suicide and homicide rates by 8% and 14%, respectively. CMHCs also reduced deaths from alcohol in the female non-white population by 18%. These results suggest the historical narrative surrounding the failure of this program does not represent the non-white experience and that community care can be effective at reducing mental health related mortality in populations with the least access to alternative treatment options.

Sex and Gender and Allostatic Mechanisms of Cardiovascular Risk and Disease

Cardiovascular diseases are leading causes of mortality and morbidity in adults worldwide. Multiple studies suggest that there are clinically relevant sex differences in cardiovascular disease. Women and men differ substantially in terms of prevalence, presentation, management, and outcomes of cardiovascular disease. To date, however, little is known about why cardiovascular disease affects women and men differently. Because many studies do not differentiate the concept of sex and gender, it is sometimes difficult to discriminate sociocultural vs biological contributors that drive observed clinical differences. Female sex has some biological advantages in relation to cardiovascular disease, but many of these advantages seem to disappear as soon as women develop cardiovascular risk factors (eg, type 2 diabetes, hypertension, dyslipidemia). Furthermore, stress and allostatic load could play an important role in the relationship between sex/gender and cardiovascular diseases. In this narrative review, we argue that chronic stress and psychosocial factors might better encompass the patterns of allostatic load increases seen in women, while biological risk factors and unhealthy behaviours might be more important mechanisms that drive increased allostatic load in men. Indeed, men show allostatic load patterns that are more associated with impaired anthropometric, metabolic, and cardiovascular functioning and women have greater dysregulation in neuroendocrine and immune functioning. Thus gender-related factors might contribute to the pathogenesis of cardiovascular disease especially through stress mechanisms. It is important to continue to study the mechanisms by which gender influences chronic stress, because chronic stress could influence modifiable gendered factors to promote cardiovascular disease prevention.

The Roles of Socioeconomic Status, Occupational Health and Job Rank on the Epidemiology of Different Psychiatric Symptoms in a Sample of UK Workers

There is a considerable gap in epidemiological literature about community mental health showing how psychiatric symptoms are associated with job rank, socioeconomic status, and occupational health. We examine data from 4596 employees collected in the United Kingdom's Psychiatric Morbidity among Adults Living in Private Households Survey. There were 939 workers in managerial jobs, 739 in supervisory jobs and 2918 employees in lower ranking jobs. Of the 4596 workers, 2463 had depressive symptoms and 2133 no depressive symptoms. Job rank, household gross income, social class, personal gross income and socio-economic group were significantly associated with general health, occupational health and depressive and avoidant symptoms. Job rank, occupational and physical health also explained the variance in paranoid and avoidant symptoms among the employees. This study shows that severe psychopathology is related to workers' job rank.

Correlates of psychological distress among workers in the mining industry in remote Australia: Evidence from a multi-site cross-sectional survey

The purpose of this study was to assess the prevalence of psychological distress in employees in the metalliferous mining industry in Australia, and to examine associated demographic, health, and workplace characteristics. A cross sectional survey was conducted among 1,799 participants from four metalliferous mines. Psychological distress was measured by the Kessler Psychological Distress Scale (K10), alongside other measures of personal demographics, health history, health behaviour, and workplace characteristics. Univariate and multivariate statistical methods were used to examine associations between psychological distress and personal and workplace characteristics. Levels of moderate to very high psychological distress were significantly higher in this sample (44.4%) compared to the general population (27.2%). Moderate to very high psychological distress was significantly associated with younger age; individual health factors (a prior history of depression, anxiety, or drug/alcohol problems); health behaviours (using illicit drugs in the last month); and a range of workplace factors (concern about losing their job; lower satisfaction with work; working shifts of over 12 hours duration; working in mining for financial reasons and social factors (poorer social networks). The identification of a number of social, personal and workplace factors associated with high psychological distress present useful targets to inform the development of tailored workplace interventions to reduce distress in metalliferous mine employees.

Employment predictors and outcomes of U.S. state-federal vocational rehabilitation consumers with affective disorders: A CHAID analysis

BACKGROUND

This study examined the demographic and rehabilitation service variables affecting employment outcomes of people with affective disorders receiving services from U.S. state-federal vocational rehabilitation (VR) agencies.

METHODS

An ex post facto design, using data mining as a statistical analysis strategy, was used to analyze the Rehabilitation Services Administration Case Service Report (RSA-911) for the fiscal year 2011. The sample included 44,960 customers with affective disorders who were closed either as successfully employed (Status 26) or not employed (Status 28) by their VR agency. The dependent variable is employment outcome. The predictor variables include a set of personal characteristic variables and rehabilitation service variables.

RESULTS

The chi-squared automatic interaction detector (CHAID) data mining analysis results indicated that job placement services, on-the-job supports, and job search assistance services were significant predictors of successful employment outcomes for individuals with affective disorders.

LIMITATIONS

The study used data from the RSA-911 database. Causality cannot be inferred due to the use of archival data.

CONCLUSIONS

Employment should be viewed as a viable treatment outcome for individuals with affective disorders. Rehabilitation professionals should advocate for their clients to receive VR services, including job placement services, on-the-job supports, and job search assistance services in order to maximize their employment and mental health outcomes.

Mental disorders and employment status in the São Paulo Metropolitan Area, Brazil: gender differences and use of health services

Abstract: Mental disorders are associated with employment status as significant predictors and as consequences of unemployment and early retirement. This study describes the estimates and associations of 12-month DSM-IV prevalence rates of mental disorders and use of health services with employment status by gender in the São Paulo Metropolitan Area, Brazil. Data from the São Paulo Megacity Mental Health Survey was analyzed (n = 5,037). This is a population-based study assessing the prevalence and determinants of mental disorders among adults, using the Composite International Diagnostic Interview. The associations were estimated by odds ratios obtained through binomial and multinomial logistic regression. This study demonstrates that having mental disorders, especially mood disorders, is associated with being inactive or unemployed among men and inactive among women, but only having a substance use disorder is associated with being unemployed among women. Among those with mental disorders, seeking health care services is less frequent within unemployed.

The Impact of Cognitive, Social and Physical Limitations on Income in Community Dwelling Adults With Chronic Medical and Mental Disorders

Introduction:

As much as 45% of the US population has at least one chronic condition while 21% have multiple chronic diseases. The study examined the impact of cognitive, social and physical limitations on the personal income of U.S. adults with seven chronic diseases.

Methods:

A cross-sectional analysis of 19,357 US adults with seven chronic diseases (diabetes, hypertension, heart disease, stroke, depression, emphysema and joint disease) from the 2006 Medical Expenditure Panel Survey (MEPS) was performed. The effect of seven chronic diseases and their associated cognitive, social, and physical limitations on personal income was assessed using a two-stage Heckman model.

Results:

Depression emerged as the only chronic disease that was independently associated with a significant $1,914 decrease in personal income (95% CI -$2,938--$890). Social and cognitive limitations resulted in $1,944 (95% CI -$3,378--$511) and $3,039 (95% CI -$4,418-$1,659) decreases in personal incomes respectively while physical limitations did not result in a statistically significant reduction. Being Non-Hispanic Black, Hispanic, Other Race, female, never married, married, less than a bachelor’s degree, publicly insured, uninsured, or having a health status less than very good were also associated with significant reductions in personal income.

Conclusions:

The findings of this study suggest a need to determine the specific limitations associated with common chronic diseases and identify appropriate compensatory strategies to reduce their impact on income.

The societal cost of depression: evidence from 10,000 Swedish patients in psychiatric care

OBJECTIVE

Depression cost studies have mainly taken a primary care perspective and should be completed with cost estimates from psychiatric care. The objectives of this study were to estimate the societal per-patient cost of depression in specialized psychiatric care in Sweden, and to relate costs to disease severity, depressive episodes, hospitalization, and patient functioning.

METHODS

Retrospective resource use data in inpatient and outpatient care for 2006-2008, as well as ICD-10 diagnoses and Global Assessment of Functioning (GAF), were obtained from the Northern Stockholm psychiatric clinic (covering half of Stockholm's population aged 18 years and above). As a complement, data from national registers on pharmaceuticals and sick leave were used in order to estimate the societal cost of depression.

RESULTS

Based on 10,430 patients (63% women), the mean annual per-patient cost was €17,279 in 2008. The largest cost item was indirect costs due to productivity losses (88%), followed by outpatient care (6%). Patients with mild and severe depression had average costs of €14,200 and €21,500, respectively. Total costs were substantially higher during depressive episodes, among patients with co-morbid psychosis or anxiety, for hospitalized patients, and for patients with poor functioning.

LIMITATIONS

Primary care costs and costs for reduced productivity at work were not included.

CONCLUSIONS

The main cost item among depression patients in psychiatric care was indirect costs. Costs were higher than previously reported for primary care, and strongly related to hospitalization, depressive episodes, and low functioning. This suggests that effective treatment that avoids depressive episodes and hospitalization may reduce society's costs for depression.

The impact of psychiatric disorders on employment: results from a national survey (NESARC)

In this study we examine the longitudinal effects of psychiatric and substance use disorders on employment, in an employed population. The sample included respondents to the National epidemiologic survey on alcohol related conditions (NESARC) who were employed at Wave 1 (N=22,407). Bivariate and multivariable analyses were conducted examining the associations between 12-month and new onset 12-month psychiatric diagnoses at Wave 1 and employment status at Wave 2. Past year and new onset 12-month depression, 12-month bipolar, new onset 12-month drug abuse, and 12-month and new onset 12-month drug dependence were associated with a decreased odds of being employed at Wave 2. This study suggests that it would be beneficial for employers to support their employees in participating in mental health treatment. Additionally, understanding how psychiatric disorders influence employment over the life course might inform the development of preemptive interventions to treat mental health symptoms.

Targeted versus tailored multimedia patient engagement to enhance depression recognition and treatment in primary care: randomized controlled trial protocol for the AMEP2 study

BACKGROUND

Depression in primary care is common, yet this costly and disabling condition remains underdiagnosed and undertreated. Persisting gaps in the primary care of depression are due in part to patients' reluctance to bring depressive symptoms to the attention of their primary care clinician and, when depression is diagnosed, to accept initial treatment for the condition. Both targeted and tailored communication strategies offer promise for fomenting discussion and reducing barriers to appropriate initial treatment of depression.

METHODS/DESIGN

The Activating Messages to Enhance Primary Care Practice (AMEP2) Study is a stratified randomized controlled trial comparing two computerized multimedia patient interventions -- one targeted (to patient gender and income level) and one tailored (to level of depressive symptoms, visit agenda, treatment preferences, depression causal attributions, communication self-efficacy and stigma)-- and an attention control. AMEP2 consists of two linked sub-studies, one focusing on patients with significant depressive symptoms (Patient Health Questionnaire-9 [PHQ-9] scores ≥ 5), the other on patients with few or no depressive symptoms (PHQ-9 < 5). The first sub-study examined effectiveness of the interventions; key outcomes included delivery of components of initial depression care (antidepressant prescription or mental health referral). The second sub-study tracked potential hazards (clinical distraction and overtreatment). A telephone interview screening procedure assessed patients for eligibility and oversampled patients with significant depressive symptoms. Sampled, consenting patients used computers to answer survey questions, be randomized, and view assigned interventions just before scheduled primary care office visits. Patient surveys were also collected immediately post-visit and 12 weeks later. Physicians completed brief reporting forms after each patient's index visit. Additional data were obtained from medical record abstraction and visit audio recordings. Of 6,191 patients assessed, 867 were randomized and included in analysis, with 559 in the first sub-study and 308 in the second.

DISCUSSION

Based on formative research, we developed two novel multimedia programs for encouraging patients to discuss depressive symptoms with their primary care clinicians. Our computer-based enrollment and randomization procedures ensured that randomization was fully concealed and data missingness minimized. Analyses will focus on the interventions' potential benefits among depressed persons, and the potential hazards among the non-depressed.

Mental disorders: employment and work productivity in Singapore

AIM

To examine the association between mental disorders and work disability in the adult resident population in Singapore.

METHOD

Data are from the Singapore Mental Health Study, which was a household survey of a nationally representative sample. The main instrument used was the Composite International Diagnostic Interview (CIDI). Employment-related information was collected using the modified employment module of the CIDI.

RESULTS

A total of 6,429 respondents were included in the analysis, 71 % (n = 4,594) were employed, 24.5 % (n = 1,522) were economically inactive and 4.5 % (n = 313) were unemployed. Among the employed, 2.3 % had a 12-month prevalence of at least one mental disorder, while 5.3 % of the unemployed had at least one mental disorder. The average number of work loss days (absenteeism) per capita among those with a mental disorder was 0.5 per month that is equivalent to an annualized national projection of approximately 0.3 million productivity days. The average work-cutback days (presenteeism) were 0.4 days among this group. Of the mentally ill in the workforce, a high proportion (86.5 %) did not ever seek help for problems related to mental health.

CONCLUSION

Our findings provide information on the significant consequences of mental disorders on the workforce in terms of lost work productivity, which could pave the way for a more rational allocation of scarce resources.

Prevalence of psychological distress, as measured by the Kessler 6 (K6), and related factors in Japanese employees

The aim of this study was to examine the prevalence of and related factors for psychological distress among employees. The employees in Akita prefecture, Japan, were invited to complete the Kessler 6 (K6). A value of 13 or higher on the K6 scale indicated high psychological distress. Furthermore, we identified the relationships among the prevalence of high psychological distress, socio-demographic status, and employment-related variables. The data of 1,709 employees indicated that 10.8% of the employees had high psychological distress; the proportion of psychological distress found in the present study was high compared to that found in previous studies. The identified socio-demographic and occupation-related factors included young age groups associated with a high risk and clerical or administrative tasks associated with a low risk of psychological distress. The data of this study can be used as K6 benchmark values, which enhance the significance of future corporate health risk appraisal surveys.

The prevalence and impact of major depressive disorder among Chinese, Malays and Indians in an Asian multi-racial population

BACKGROUND

Reports of rates of depression among different Asian ethnic groups within the same country using standardized assessments are rare in the extant literature.

METHODS

This was a household survey of 6616 adult residents of Singapore which constituted a national representative sample. Face to face interviews were conducted with the English, Chinese and Malay versions of the World Mental Health Composite International Diagnostic Interview. The response rate was 75.9%.

RESULTS

The lifetime and 12-month prevalence estimates for MDD were 5.8% and 2.2%, respectively. MDD was significantly higher among the females, Indians, those who were divorced/separated, or widowed. The median age of onset of MDD was 26 years with the highest risk of onset in those aged 18-34 years while the age group of 65 years and above had the lowest risk of onset. Chronic physical conditions were present in approximately half of the respondents with MDD. MDD was also associated with considerable disability in terms of days of role impairment. More than half (59.6%) of those with lifetime MDD had not ever sought professional help.

LIMITATIONS

This was a cross-sectional household survey that excluded those who were institutionalized. Responses were self-reported and therefore subjected to recall bias.

CONCLUSIONS

Our findings add to the body of knowledge on the differential rates of depression among different ethnic groups; the association with disability, comorbid physical conditions and the considerable proportion of untreated cases also have important clinical and policy implications.

Receiving treatment, labor force activity, and work performance among people with psychiatric disorders: results from a population survey

INTRODUCTION

Standard treatments for psychiatric disorders such as schizophrenia, depression and anxiety disorders are generally expected to benefit individuals, employers, and the wider community through improvements in work-functioning and productivity.

METHODS

We repeated a previous secondary investigation of receiving treatment, labor force activity and self-reported work performance among people with ICD-10 psychiatric disorders, in comparison to people with other types of health conditions. Data were collected by the Australian Bureau of Statistics in 2003 repeating a survey administered in 1998 using representative multistage sampling strategies. The 2003 household probability sample consisted of 36,241 working age individuals.

RESULTS

Consistent with the previous secondary investigation based on the 1998 survey administration, receiving treatment was consistently associated with non-participation in the labor force, and was negatively associated with work performance.

CONCLUSIONS

At a population level, receiving treatment was negatively associated with labor force activity and work performance. The stability of these results in two independent surveys highlights the need to investigate the longitudinal relationships between evidence-based treatments for psychiatric conditions as applied in real-world settings, and labor force participation and work performance outcomes.

Association between major depression, depressive symptoms and personal income in US adults with diabetes

OBJECTIVE

Although the association between diabetes and depression outcomes has been well studied, very little is known about the association between depression and personal income in adults with diabetes. We examined the association between major depression, number of depressive symptoms and personal income among individuals with diabetes.

METHODS

We used the two-stage Heckman procedure to estimate adjusted personal income by major depression status and number of depressive symptoms for 1818 adults with diabetes from the nationally representative 2006 Medical Expenditure Panel Survey. STATA V.10 was used for statistical analysis to account for the complex survey design.

RESULTS

In a fully adjusted model with major depression as a binary variable, major depression was associated with $2838 lower personal income. In a separate model with depressive symptoms as a continuous variable, each additional symptom was associated with $1235 lower personal income. Compared with being white/non-Hispanic, being black/non-Hispanic (-$4640) was associated with decreased personal income. Compared with excellent health status, fair health status (-$12,172) and poor health status (-$13,835) were associated with lower income. Relative to private insurance, public insurance only (-$8413) and being uninsured (-$9600) were associated with decreased income.

CONCLUSIONS

Among adults with diabetes, major depression and depressive symptoms are associated with lower personal income, after adjusting for relevant confounders. This finding suggests that aggressively diagnosing and treating depression as well as keeping people free of depressive symptoms can have huge human capital savings over the employment lifetime of individuals with diabetes and depression.

Using the interaction of mental health symptoms and treatment status to estimate lost employee productivity

OBJECTIVE

In Australia it has been estimated that mental health symptoms result in a loss of $ AU2.7 billion in employee productivity. To date, however, there has been only one study quantifying employee productivity decrements due to mental disorders when treatment-seeking behaviours are considered. The aim of the current paper was to estimate employee work productivity by mental health symptoms while considering different treatment-seeking behaviours.

METHOD

A total of 60 556 full-time employees responded to the World Health Organization Health and Work Performance Questionnaire. This questionnaire is designed to monitor the work productivity of employees for chronic and acute physical and mental health conditions. Contained within the questionnaire is the Kessler 6, a scale measuring psychological distress along with an evaluation of employee treatment-seeking behaviours for depression, anxiety and any other emotional problems. A univariate analysis of variance was performed for employee productivity using the interaction between Kessler 6 severity categories and treatment-seeking behaviours.

RESULTS

A total of 9.6% of employees have moderate psychological distress and a further 4.5% have high psychological distress. Increasing psychological distress from low to moderate then to high levels is associated with increasing productivity decrements (6.4%, 9.4% and 20.9% decrements, respectively) for employees in current treatment. Combining the prevalence of Kessler 6 categories with treatment-seeking behaviours, mean 2009 salaries and number of Australian employees in 2009, it is estimated that psychological distress produces an $ AU5.9 billion reduction in Australian employee productivity per annum.

CONCLUSIONS

The estimated loss of $ AU5.9 billion in employee productivity due to mental health problems is substantially higher than previous estimates. This finding is especially pertinent given the global economic crisis, when psychological distress among employees is likely to be increasing. Effective treatment for mental health problems yields substantial increases in employee productivity and would be a sound economic investment for employers.

Preparing the ethical future of deep brain stimulation

BACKGROUND

Deep brain stimulation is an approved and effective neurosurgical intervention for motor disorders such as PD and ET. Deep brain stimulation may also be effective in treating a number of psychiatric disorders, including treatment refractory depression and OCD. Although DBS is a widely accepted therapy in motor disorders, it remains an invasive and expensive procedure. The ethical and social challenges of DBS need further examination, and discussion and emerging applications of DBS in psychiatry may also complicate the ethical landscape of DBS.

METHODS

To identify and characterize current and emerging issues in the use of DBS, we reviewed the neurosurgical literature on DBS as well as the interdisciplinary medical ethics and relevant psychological and sociological literatures. We also consulted the USPTO database, FDA regulations and report decisions, and the business reports of key DBS manufacturers.

RESULTS

Important ethical and social challenges exist in the current and extending practice of DBS, notably in patient selection, informed consent, resource allocation, and in public understanding. These challenges are likely to be amplified if emerging uses of DBS in psychiatry are approved.

CONCLUSIONS

Our review of ethical and social issues related to DBS highlights that several significant challenges, although not insurmountable, need much closer attention. A combination of approaches previously used in neuroethics, such as expert consensus workshops to establish ethical guidelines and public engagement to improve public understanding, may be fruitful to explore.

The importance of functional impairment to mental health outcomes: a case for reassessing our goals in depression treatment research

Outcomes in depression treatment research include both changes in symptom severity and functional impairment. Symptom measures tend to be the standard outcome but we argue that there are benefits to considering functional outcomes. An exhaustive literature review shows that the relationship between symptoms and functioning remains unexpectedly weak and often bidirectional. Changes in functioning often lag symptom changes. As a result, functional outcomes might offer depression researchers more critical feedback and better guidance when studying depression treatment outcomes. The paper presents a case for the necessity of both functional and symptom outcomes in depression treatment research by addressing three aims-1) review the research relating symptoms and functioning, 2) provide a rationale for measuring both outcomes, and 3) discuss potential artifacts in measuring functional outcomes. The three aims are supported by an empirical review of the treatment outcome and epidemiological literatures.

Mental health and the workplace: issues for developing countries

The capacity to work productively is a key component of health and emotional well-being. Common Mental Disorders (CMDs) are associated with reduced workplace productivity. It is anticipated that this impact is greatest in developing countries. Furthermore, workplace stress is associated with a significant adverse impact on emotional wellbeing and is linked with an increased risk of CMDs. This review will elaborate on the relationship between workplace environment and psychiatric morbidity. The evidence for mental health promotion and intervention studies will be discussed. A case will be developed to advocate for workplace reform and research to improve mental health in workplaces in developing countries in order to improve the wellbeing of employees and workplace productivity.

Depression and retirement in late middle-aged U.S. workers

OBJECTIVE

To determine whether late middle-aged U.S. workers with depression are at an increased risk for retirement.

DATA SOURCE

Six biennial waves (1992-2002) of the Health and Retirement Study, a nationally representative panel survey of noninstitutionalized 51-61-year-olds and their spouses started in 1992.

STUDY DESIGN

Workers aged 53-58 years in 1994 were followed every 2 years thereafter, through 2002. Depression was coded as lagged time-dependent variables measuring active depression and severity of depression. The main outcome variable was a transition to retirement which was measured using two distinct definitions to capture different stages in the retirement process: (1) Retirement was defined as a transition out of the labor force in the sample of all labor force participants (N=2,853); (2) In addition a transition out of full time work was used as the retirement definition in the subset of labor force participants who were full time workers (N=2,288).

PRINCIPAL FINDINGS

In the sample of all labor force participants, the presence of active depression significantly increased the hazard of retirement in both late middle-aged men (adjusted OR: 1.37 [95 percent CI 1.05, 1.80]) and women (adjusted OR: 1.40 [95 percent CI 1.10, 1.78]). For women, subthreshold depression was also a significant predictor of retirement. In the sample of full time workers, the relationship between depression and retirement was considerably weaker for women yet remained strong for men.

CONCLUSIONS

Depression and depressive symptoms were significantly associated with retirement in late middle-aged U.S. workers. Policymakers must consider the potentially adverse impact of these labor market outcomes when estimating the cost of untreated depression and evaluating the value of interventions to improve the diagnosis and treatment of depression.

Depression and the workplace: a progress report

There has been considerable interest recently in the relationship between depression and the workplace. This interest is driven by the growing recognition that depressive disorders are highly prevalent in the workplace and have an enormously negative impact on performance, productivity, absenteeism, and disability costs. A variety of clinical research with occupational-related samples has helped to define those at risk for depression and has led to a better understanding of the overlap of the construct of clinical depression with more longstanding occupational health and organizational psychology models such as stress, burnout, and job satisfaction. From an employer perspective, depression's impact remains largely unmitigated due to stigma, uncertainty about treatment's cost effectiveness, and lack of effective interventions delivered in a workplace setting. Progress in these areas is reviewed with suggestions for future directions.

Receiving treatment and labor force activity in a community survey of people with anxiety and affective disorders

INTRODUCTION

Standard treatments for depression and anxiety disorders are generally expected to benefit individuals, employers, and the wider community through improvements in work-functioning and productivity. Although some evidence supports expectations of treatment benefits, these are rarely examined at a population level.

METHODS

We investigated receiving treatment, labor force activity, and self-reported work performance among people with ICD-10 affective and anxiety disorders. Data were collected by the Australian Bureau of Statistics using representative multistage sampling strategies. This large household probability sample consisted of 37,580 working age individuals. A secondary analysis was conducted using multiple binary logistic regression.

RESULTS

After statistically controlling for eight covariates: extent of employment restrictions; mental health status; age; sex; partner status; country of birth; age left school; and educational attainment; receiving treatment was consistently associated with non-participation in the labor force, and was negatively associated with work performance.

CONCLUSIONS

At a population level, receiving treatment for anxiety and depression was negatively associated with being employed or looking for work. This could be an unintended side effect of treatment, although other explanations are also possible. These results justify more specific longitudinal investigations into how different forms of mental health treatment influence labor force activity among working age community residents with anxiety and affective disorders.

Psychosocial and pharmacological interventions for depressed adults in primary care: a critical review

Primary care settings are the principal context for treating clinical depression, with researchers beginning to explore the efficacy of psychosocial and pharmacological treatments for depression within this infrastructure. Feasibility and process variables also are being assessed, including issues of cost-effectiveness, viability of collaborative care models, predictors of treatment outcome, and effectiveness of treatment providers without specialized mental health training. The Agency for Health Care Policy and Research and American Psychiatric Association initially released guidelines for the treatment of depression in primary care [American Psychiatric Association, 1993. Practice Guidelines for major depressive disorder in adults. American Journal of Psychiatry, 150, 1-26., American Psychiatric Association, 2000. Practice Guideline for the treatment of patients with major depressive disorder (revision). American Journal of Psychiatry, 157, 1-45], however, a vast literature has accumulated over the past several years, calling for a systematic re-evaluation of the status of depression treatment in primary care. The present study provides a contemporary review of outcome data for psychosocial and pharmacological interventions in primary care and extends beyond AHCPR guidelines insofar as focusing on feasibility and process variables, including the training and proficiency of primary care treatment providers, cost-effectiveness of primary care interventions, and predictors of treatment response and relapse. Based on current guidelines, problem-solving therapy (PST-PC), interpersonal psychotherapy, and pharmacotherapy would be considered efficacious interventions for major depression, with cognitive-behavioral and cognitive therapy considered possibly efficacious. Psychotherapy and pharmacotherapy generally are of comparable efficacy, and both modalities are superior to usual care in treating depression. Methodological limitations and directions for future research are discussed.

Reducing the societal burden of depression: a review of economic costs, quality of care and effects of treatment

Depression is a highly prevalent condition that results in substantial functional impairment. Advocates have attempted in recent years to make the 'business case' for investing in quality improvement efforts in depression care, particularly in primary care settings. The business case suggests that the costs of depression treatment may be offset by gains in worker productivity and/or reductions in other healthcare spending. In this paper, we review the evidence in support of this argument for improving the quality of depression treatment. We examined the impact of depression on two of the primary drivers of the societal burden of depression: healthcare utilisation and worker productivity. Depression leads to higher healthcare utilisation and spending, most of which is not the result of depression treatment costs. Depression is also a leading cause of absenteeism and reduced productivity at work. It is clear that the economic burden of depression is substantial; however, critical gaps in the literature remain and need to be addressed. For instance, we do not know the economic burden of untreated and/or inappropriately treated versus appropriately treated depression. There remain considerable problems with access to and quality of depression treatment. Progress has been made in terms of access to care, but quality of care is seldom consistent with national treatment guidelines. A wide range of effective treatments and care programmes for depression are available, yet rigorously tested clinical models to improve depression care have not been widely adopted by healthcare systems. Barriers to improving depression care exist at the patient, healthcare provider, practice, plan and purchaser levels, and may be both economic and non-economic. Studies evaluating interventions to improve the quality of depression treatment have found that the cost per QALY associated with improved depression care ranges from a low of 2519 US dollars to a high of 49,500 US dollars. We conclude from our review of the literature that effective treatment of depression is cost effective, but that evidence of a medical or productivity cost offset for depression treatment remains equivocal, and this points to the need for further research in this area.

Exploring and validating patient concerns: relation to prescribing for depression

PURPOSE

This study examined moderating effects of physician communication behaviors on relationships between patient requests for antidepressant medications and subsequent prescribing.

METHODS

We conducted a secondary analysis of a randomized trial. Primary care physicians (N = 152) each had 1 or 2 unannounced visits from standardized patients portraying the role of major depression or adjustment disorder. Each standardized patient made brand-specific, general, or no requests for antidepressants. We coded covert visit audio recordings for physicians' exploration and validation of patient concerns (EVC). Effects of communication on prescribing (the main outcome) were evaluated using logistic regression analysis, accounting for clustering and for site, physician, and visit characteristics, and stratified by request type and standardized patient role.

RESULTS

In the absence of requests, high-EVC visits were associated with higher rates of prescribing of antidepressants for major depression. In low-EVC visits, prescribing was driven by patient requests (adjusted odds ratio [AOR] for request vs no request = 43.54, 95% confidence interval [CI], 1.69-1,120.87; P < or = .005), not clinical indications (AOR for depression vs adjustment disorder = 1.82; 95% CI, 0.33-9.89; P = NS). In contrast, in high-EVC visits, prescribing was driven equally by requests (AOR = 4.02; 95% CI, 1.67-9.68; P < or = .005) and clinical indications (AOR = 4.70; 95% CI, 2.18-10.16; P < or = .005). More thorough history taking of depression symptoms did not mediate these results.

CONCLUSIONS

Quality of care for depression is improved when patients participate more actively in the encounter and when physicians explore and validate patient concerns. Communication interventions to improve quality of care should target both physician and patient communication behaviors. Cognitive mechanisms that link patient requests and EVC to quality of care warrant further study.

Work performance among Australians with depression and anxiety disorders: a population level second order analysis

At a population level, little is known about how anxiety and depression impact on work performance. We investigated the first and second order correlates of work accomplishment and care taken at work among people with International Statistical Classification of Diseases and Related Health Problems, 10th Revision, affective and anxiety disorders in comparison to healthy community residents. Australian Bureau of Statistics multistage sampling strategies obtained a household sample of 37,580 working age individuals. A secondary analysis was conducted using multiple binary logistic regression. The first order correlates of work performance were the extent of employment restrictions, mental health status, age, sex, and whether or not treatment was received. At the second order level, the effects of mental health status on work performance depended on age, sex, and receiving treatment. The effect of employment restrictions on work performance depended on age and sex only.

Job performance deficits due to depression

OBJECTIVE

This study assessed the relationship between depression severity and job performance among employed primary care patients.

METHOD

In a 2001-2004 longitudinal observational study of depression's affect on work productivity, 286 patients with DSM-IV major depressive disorder and/or dysthymia were compared to 93 individuals with rheumatoid arthritis, a condition associated with work disability, and 193 depression-free healthy control subjects. Participants were employed at least 15 hours per week, did not plan to stop working, and had no major medical comorbidities. Measures at baseline, six, 12, and 18 months included the Work Limitations Questionnaire for work outcomes, and the Patient Health Questionnaire-9 for depression.

RESULTS

At baseline and each follow-up, the depression group had significantly greater deficits in managing mental-interpersonal, time, and output tasks, as measured by the Work Limitations Questionnaire: The rheumatoid arthritis group's deficits in managing physical job demands surpassed those of either the depression or comparison groups. Improvements in job performance were predicted by symptom severity. However, the job performance of even the "clinically improved" subset of depressed patients remained consistently worse than the control groups.

CONCLUSIONS

Multiple dimensions of job performance are impaired by depression. This impact persisted after symptoms have improved. Efforts to reduce work-impairment secondary to depression are needed.

Mental illness and employment discrimination

PURPOSE OF REVIEW

Work is a major determinant of mental health and a socially integrating force. To be excluded from the workforce creates material deprivation, erodes self-confidence, creates a sense of isolation and marginalization and is a key risk factor for mental disability. This review summarizes recent evidence pertaining to employment-related stigma and discrimination experienced by people with mental disabilities. A broad understanding of the stigmatization process is adopted, which includes cognitive, attitudinal, behavioural and structural disadvantages.

RECENT FINDINGS

Stigma is both a proximate and a distal cause of employment inequity for people with a mental disability who experience direct discrimination because of prejudicial attitudes from employers and workmates and indirect discrimination owing to historical patterns of disadvantage, structural disincentives against competitive employment and generalized policy neglect. Against this background, modern mental health rehabilitation models and legislative philosophies, which focus on citizenship rights and full social participation, are to be welcomed. Yet, recent findings demonstrate that the legislation remains vulnerable to the very prejudicial attitudes they are intended to abate.

SUMMARY

Research conducted during the past year continues to highlight multiple attitudinal and structural barriers that prevent people with mental disabilities from becoming active participants in the competitive labour market.

Common mental disorders in the workforce: recent findings from descriptive and social epidemiology

OBJECTIVE

To review the recent descriptive and social epidemiology of common mental disorders in the workplace, including prevalence, participation, work disability, and impact of quality of work, as well as to discuss the implications for identifying targets for clinical and preventive interventions.

METHOD

We conducted a structured review of epidemiologic studies in community settings (that is, in the general population or in workplaces). Evidence was restricted to the peer-reviewed, published, English-language literature up to the end of June 2005. We further restricted evidence to studies that used recent classification systems; then, if evidence was insufficient, we reviewed studies that used standardized psychiatric screening scales. To distinguish this article from recent reviews of health and work quality, we focused on new areas of investigation and new evidence for established areas of investigation: underemployment, organizational justice, job control and demand, effort-reward imbalance, and atypical (nonpermanent) employment.

RESULTS

Depression and simple phobia were found to be the most prevalent disorders in the working population. The limited data on rates of participation suggested higher participation among people with depression, simple phobia, social phobia, and generalized anxiety disorder. Depression and anxiety were more consistently associated with "presenteeism" (that is, lost productivity while at work) than with absenteeism, whether this was measured by cutback days or by direct questionnaires. Seven longitudinal studies, with an average sample size of 6264, showed a strong association between aspects of low job quality and incident depression and anxiety. There was some evidence that atypical work was associated with poorer mental health, although the findings for fixed-term work were mixed.

CONCLUSIONS

Mental health risk reduction in the workplace is an important complement to clinical interventions for reducing the current and future burden of depression and anxiety in the workplace.

The relationship of depression treatment quality indicators to employee absenteeism

Although employers commonly review administrative database indicators to assess depression treatment quality, they do not know whether these indicators predict relevant outcomes like absenteeism. In 230 employed patients in five health plans, we tested how administrative database-derived indicators for antidepressant medication and psychotherapy provided during the first 6 months of a new depression treatment episode predicted patient-reported absenteeism change over 12 months. The medication indicator was not significantly associated with absenteeism change over 12 months (p = .64); however, the psychotherapy indicator was significantly associated with an average 26.1% improvement in absenteeism over 12 months (p < .05). If subsequent studies confirm the results we report, quality monitoring initiatives interested in employer-relevant indicators of depression treatment quality should examine administrative database indicators of psychotherapy.

Do antidepressants reduce the burden imposed by depression on employers?

The ability to perform paid or unpaid work is integral to an individual's quality of life. Therefore, we performed a systematic literature review to examine the impact of depression and its treatment on occupational outcomes. This review found absenteeism from work to be markedly higher among depressed employees and productivity to be dramatically undermined by some symptoms of depression. Gaps in the published literature point to the need for future economic and clinical analyses to include work-related outcomes. Published studies showed that antidepressants can enhance work-related outcomes by alleviating affective symptoms. However, the pharmacological properties of antidepressants may produce differential effects that influence work-related outcomes in other ways. For example, TCAs, but not SSRIs, produce sedation and impair cognitive function in ways that could undermine work-related outcomes. Formal analyses are required to quantify whether the improved social functioning, motivation and vigilance that may be associated with some newer antidepressants translate into improved work-related outcomes. Although few published studies have directly quantified the cost benefit of managing depression and associated lost productivity, existing studies that directly assessed work-related outcomes have suggested that treating depression is cost effective. Gaps in the published literature imply that the impact of depression and antidepressants on occupational outcomes has been understudied. This reflects, in part, the fact that antidepressant studies lasting 4 or 6 weeks are unlikely to capture the impact of treatment on work-related measures. In addition, the current evidence base is fraught with other methodological limitations. The effect of depression on non-paid employment also requires further assessment. In conclusion, the efficacy of antidepressants on work-related outcomes should be measured in clinical trials that have an adequate design and a suitable follow-up period, and included in health technology assessments. Until such studies are available, the evidence base supporting the use of antidepressants will remain incomplete.

The community initiative on depression: report from a multiphase work site depression intervention

OBJECTIVE

We sought to further understand depression, a common, disabling condition with considerable ramifications for the workplace, including higher costs, absenteeism, and reduced work performance.

METHODS

A multidisciplinary health care coalition recently implemented a multiphase workplace depression initiative in Kansas City. We report results from its first phase, a 22-item, self-administered survey of depression knowledge and attitudes among employees of 13 large, local work sites.

RESULTS

There were 6,399/38,945 respondents (16% response rate). Most respondents (>90%) appropriately recognized the signs and symptoms of depression. A minority (29%) would feel comfortable discussing depression with their supervisor. Sixty-two percent knew how to access company resources for depression care.

CONCLUSIONS

Employees were knowledgeable about depression but were less aware of employee-assistance programs for depression care. These findings support increased attempts to raise the awareness of depression and promote of help-seeking behavior in the workplace.

CLINICAL SIGNIFICANCE

Depression is a prevalent illness with risk for many deleterious outcomes if under-recognized or undertreated. Depression is a leading cause of work-related disability worldwide. Most people with depression are employed (an estimated 68%). Recognizing and initiating depression care in the workplace will facilitate depression treatment in clinical settings.

Unemployment, job retention, and productivity loss among employees with depression

OBJECTIVE

This study comprehensively assessed the work outcomes of employees with depression.

METHODS

We collected baseline and six-month follow-up survey data from 229 employees with depression and two employee comparison groups: a group of healthy patients for the control group (N=173) and a group with rheumatoid arthritis (N=87), a frequent source of work disability. Outcomes included new unemployment and, within the employed subgroup, job retention (versus job turnover), presenteeism (that is, diminished on-the-job performance and productivity), and absenteeism.

RESULTS

At the six-month follow-up, persons with depression had more new unemployment--14 percent for persons in the dysthymia group, 12 percent for persons in the major depression group, and 15 percent for persons in the group with both dysthymia and major depression, compared with 2 percent for persons in the control group and 3 percent for persons in the rheumatoid arthritis group. Among participants who were still employed, those with depression had significantly more job turnover, presenteeism, and absenteeism.

CONCLUSIONS

In addition to helping employees with depression obtain high-quality depression treatment, new interventions may be needed to help them to overcome the substantial job upheaval that this population experiences.

Reducing the burden of affective disorders: is evidence-based health care affordable?

BACKGROUND

Affective disorders remain the leading cause of disability burden despite the availability of efficacious treatment. A wider dissemination of evidence-based health care is likely to impact this burden, however the affordability of such a strategy at the population level is unknown. This study calculated the cost-effectiveness of evidence-based health care for depression, dysthymia and bipolar disorder in the Australian population, and determined whether it was affordable, based on current mental health-related expenditure and outcomes for these disorders.

METHODS

Cost-effectiveness was expressed in costs per years lived with disability (YLDs) averted, a population health summary measure of disability burden. Data from the Australian National Survey of Mental Health and Wellbeing, in conjunction with published randomized trials and direct cost estimates, were used to estimate the 1-year costs and YLDs averted by current health care services, and costs and outcomes for an optimal strategy of evidence-based health care.

RESULTS

Current direct mental health-related health care costs for affective disorders in Australia were 615 million dollars (1997-98 Australian dollars). This treatment averted just under 30,000 YLDs giving a cost-effectiveness ratio of 20,633 dollars per YLD. Outcome could be increased by nearly 50% at similar cost with implementation of an evidence-based package of optimal treatment, halving the cost-effectiveness ratio to 10,737 dollars per YLD.

LIMITATIONS

The method to estimate YLDs averted from the literature requires replication. The costs of implementing evidence-based health care have not been estimated.

CONCLUSIONS

Evidence-based health care for affective disorders should be encouraged on both efficacy and efficiency grounds.

Relationship between depression and work outcomes following liver transplantation: the nursing perspective

About 15% of Americans will experience a major depressive disorder during their lives (Stuart, 1994). Depression is defined by the daily persistence of depressed mood throughout the day, or the marked and regular loss of interest in regular daily activities (Stuart). Research indicates persons with chronic illnesses have higher rates of depression than the general public. Recent evidence indicates individuals who have undergone liver transplantation often have significant psychiatric morbidity, including depression (Merz, 1998). A consequence of depression is often the inability to work or attend school. The effect depression has on posttransplant return to work, however, is not fully understood.The purpose of this study was to describe the relationship between depression and work outcomes among adult liver transplant recipients. Laffrey's (1986) conception of health was the theoretical framework used to guide the study. The study was part of a larger cross-sectional survey that examined return to work following liver transplant (Newton, 1997). The findings indicated that depression following liver transplant seriously impacts recipient return to work. Nursing implications related to depression and work outcomes posttransplant are also addressed.

Pharmacoeconomic studies of antidepressants: focus on venlafaxine

Newer antidepressants are more expensive in terms of acquisition costs than older drugs. However, cost effectiveness simulations and retrospective analyses of administrative databases of newer antidepressants, including venlafaxine, suggest that the higher acquisition costs may be offset or more than offset by savings of other treatment costs. Because simulations and retrospective studies are vulnerable to multiple methodologic uncertainties, large scale randomized "real-world" cost effectiveness experiments are needed. If venlafaxine in actual practice is more effective or has a more rapid onset of action than SSRIs as suggested by efficacy studies and existing meta-analyses, these effects could translate into pharmacoeconomic advantages.

Analysis of a managed psychiatric disability program

The cost of mental illness to employers has been well documented; however, efforts to effectively reduce the costs of psychiatric disability are adversely affected by the fragmentation of health care services. This report is a case study of a program in which a managed behavioral health care organization managed the psychiatric disability of a telecommunications company. Compared with a non-random cohort of claimants not managed under the pilot, the duration of disability was reduced by 23% (17.1 days). Patient and provider satisfaction with the program was high. This study illustrates the potential for effectively reducing the cost of psychiatric disability and the challenges in coordinating health care.

Lost productivity among full-time workers with mental disorders

BACKGROUND: Few studies have systematically compared the relationship between lost work productivity (work impairment) and mental disorders using population surveys. AIMS: (1) To identify the importance of individual mental disorders and disorder co-occurrences (comorbidity) as predictors of two measures of work impairment over the past month - work loss (number of days unable to perform usual activities) and work cutback (number of days where usual activities were restricted); (2) to examine whether different types of disorder have a greater impact on work impairment in some occupations than others; (3) to determine whether work impairment in those with a disorder is related to treatment seeking. METHOD: Data were based on full-time workers identified by the Australian National Survey of Mental Health and Well-Being, a household survey of mental disorders modeled on the US National Comorbidity Survey. Diagnoses were of one-month DSM-IV affective, anxiety and substance-related disorders. Screening instruments generated likely cases of ICD-10 personality disorders. The association of disorder types and their co-occurrences with work impairment was examined using multivariate linear regression. Odds ratios determined the significance of mental disorder prevalence across occupations, and planned contrasts were used to test for differences in work impairment across occupations within disorder types. The relationship between work impairment and treatment seeking was determined for each broad diagnostic group with t-tests. RESULTS: Depression, generalized anxiety disorder and personality disorders were predictive of work impairment after controlling for impairment due to physical disorders. Among pure and comorbid disorders, affective and comorbid anxiety-affective disorders respectively were associated with the greatest amount of work impairment. For all disorders, stronger associations were obtained for work cutback than for work loss. No relationship was found between type of occupation and the impact of different types of disorder on work impairment. Only 15% of people with any mental disorder had sought help in the past month. For any mental disorder, significantly greater work loss and work cutback was associated with treatment seeking, but comparisons within specific disorder types were not significant. DISCUSSION: A substantial amount of lost productivity due to mental disorders comes from within the full-time working population. The greater impact of mental disorders on work cutback compared to work loss suggests that work cutback provides a more sensitive measure of work impairment in those with mental disorders. Work impairment was based on self-report only. While there is evidence for the reliability of self-assessed work loss days, no reliability or validity studies have been conducted for work cutback days. The low rates of treatment seeking are a major health issue for the workforce, particularly for affective and anxiety disorders, which are important predictors of lost productivity. IMPLICATIONS FOR HEALTH POLICIES AND FURTHER RESEARCH: Future research should investigate the validity of work cutback, given its importance as a measure of lost productivity in people with mental disorders. Employers need to be aware of the extent to which mental disorders affect their employees so that effective work place interventions can take place. Treatment should be targeted at people with affective and anxiety disorders, particularly where they co-occur.

Large employers' selection criteria in purchasing behavioral health benefits

To determine the criteria other than cost large employers use in selecting and monitoring behavioral health benefits, this study interviewed 31 of 44 (70.4%) randomly selected corporations employing at least 5,000 workers. While more than 60% of employers considered administrative efficiency and provider access to be very influential in their selection of behavioral health benefits, only 12.9% (95% confidence interval 0.7%-25.1%) considered clinical outcomes. Employers who considered clinical outcomes in their purchasing decision reported significantly greater satisfaction with the quality and cost of their behavioral health benefits. Following selection, 38.7% of corporations used employee complaints to monitor quality problems in their behavioral health benefits; 3.2% used clinical outcomes. If society expects employers to purchase behavioral health care on the basis of quality as well as cost, more employers need better indicators of quality.
