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

Utilization and barriers to mental health services among depressed medical interns: a prospective multisite study

BACKGROUND

Compared with graduate students and young adults in the general population, depression is more prevalent among training physicians, yet physicians are often reluctant to seek mental health treatment. The purpose of this study is to identify perceived barriers to mental health treatment among depressed training physicians.

METHODS

Subjects for this study were drawn from intern classes during the 2007-2008 and 2008-2009 academic years from 6 and 13 participating community and university hospitals, respectively. At 3-month intervals throughout the intern year, participants completed the Patient Health Questionnaire regarding current depressive symptoms and questions regarding current mental health treatment. We explored potential barriers to mental health treatment at the end of the intern year and determined the proportion of subjects screening positive for depression and seeking treatment through analysis of subject responses. Stepwise binary logistic regression was conducted to compare baseline characteristics among depressed interns who sought mental health treatment and those that did not.

RESULTS

Of the 42.5% (278 of 654) of interns who screened positive for depression, 22.7% (63 of 278) reported receiving treatment during the intern year. The most frequently cited barriers to seeking treatment were time (91.5%), preference to manage problems on their own (75.1%), lack of convenient access (61.8%), and concerns about confidentiality (57.3%). Interns who had previously sought treatment for depression were more likely to seek treatment during internship.

CONCLUSIONS

Despite high rates of depression, few interns appear to seek mental health treatment due to time constraints, lack of convenient access, concerns about confidentiality, and a preference to manage problems on their own. By identifying barriers to mental health treatment we can begin to remove obstacles to the delivery of evidence-based treatments and implement prevention, screening, and early detection programs to improve the mental health of physicians in training.

The Child Asthma Link Line: a coalition-initiated, telephone-based, care coordination intervention for childhood asthma

BACKGROUND

Childhood asthma is a complex chronic disease that poses significant challenges regarding management, and there is evidence of disparities in care. Many medical, psychosocial, and health system factors contribute to recognized poor control of this most prevalent illness among children, with resultant excessive use of emergency departments and hospitalizations for care. Recent national guidelines emphasize the need for community-based initiatives to address these critical issues. To address health system fragmentation and impact asthma outcomes, the Philadelphia Allies Against Asthma coalition developed and implemented the Child Asthma Link Line, a telephone-based care coordination and system integration program, which has been in operation since 2001. This study evaluates the effectiveness of the Child Asthma Link Line integration model to improve asthma management by measuring utilization markers of morbidity.

METHODS

Medicaid Managed Care Organization claims data for 59 children who received the Link Line intervention in 2003 are compared to a matched sample of 236 children who did not receive the Link Line intervention. Children in the two study groups are ages 3 through 12 years and matched on 2003 emergency department visits, age, gender, and race/ethnicity. Primary outcome variables analyzed in this study are emergency department visits, hospitalizations, and office visit claims from the follow-up year (2004).

RESULTS

Link Line intervention children were significantly less likely to have follow-up hospitalizations than matched sample children (p = .02). Children enrolled in the Link Line were also more likely to attend outpatient office visits in the follow-up year (p = .045). In addition, Link Line children with multiple emergency department visits in 2003 were significantly less likely to have an emergency department visit in 2004 (p = .046).

CONCLUSION

This coalition-developed, telephone-based, system-level intervention had a significant impact on childhood asthma morbidity as measured by utilization endpoints of follow-up hospitalizations and emergency department visits. Telephone-based care coordination and service integration may be a viable and economic way to impact childhood asthma and other chronic diseases.

Improving health and productivity of depressed workers: a pilot randomized controlled trial of telephone cognitive behavioral therapy delivery in workplace settings

OBJECTIVE

To examine the feasibility of telephone-delivered cognitive behavioral therapy (T-CBT) in an occupational context, with reference to participant recruitment, treatment adherence, follow-up and effect.

METHOD

Eligible participants comprised all employees of a large communications company with authorized work absence due to mild/moderate mental health difficulties over a 10-month period. Fifty-three consenting participants were centrally randomized to 12 weeks T-CBT or usual care, with minimization on age, gender and illness severity. Primary (symptom severity) and secondary outcomes (self-rated work performance and productivity) were measured at baseline and 3-months via postal questionnaires. Intention-to-treat analysis comprised multiple regression modeling with adjustment for missing response predictors, minimization variables and baseline values.

RESULTS

Twenty-three employees attended one or more T-CBT sessions. T-CBT was associated with medium-large effects sizes on clinical outcomes (0.63-0.77) and work productivity scores (0.75-0.88). Twenty-one patients failed to return 3-month primary outcome data. Non-respondents were more likely to be male and more severely ill.

CONCLUSION

Delivery of T-CBT in an occupational context is feasible with evidence of potential effect. Larger-scale trials are warranted. These studies demand assertive outreach or telephone-based assessment strategies in order to maximize participant recruitment and follow-up.

Can a ‘return-to-work’ agenda fit within the theory and practice of CBT for depression and anxiety disorders?

Helping service users to return to work has emerged as a key therapeutic objective of the Improving Access to Psychological Therapies (IAPT) initiative. IAPT programmes implement National Institute for Health and Clinical Excellence (NICE) guidelines, especially cognitive behaviour therapy (CBT), for people suffering from anxiety and depression. However, relatively little research has been conducted to date into whether, or how, cognitive behavioural interventions can help individuals return to work. This paper reviews literature and research into CBT and occupational outcomes and considers whether a return-to-work agenda may jeopardize the therapeutic alliance which is suggested to be necessary for effective CBT. Moreover, through the use of clinical examples from our practice, we suggest ways in which employment issues might be integrated into CBT for depression and anxiety disorders. We conclude that a return-to-work agenda can be utilized during therapy while maintaining a collaborative and secure therapeutic relationship, especially, perhaps if work issues are embedded within the formulation. However, further research is needed, not only to determine whether CBT can help individuals return to work but also how CBT might best integrate a return-to-work agenda.

Work performance of employees with depression: the impact of work stressors

PURPOSE

Depressed employees are vulnerable to adverse work outcomes. We hypothesized that work performance is impaired by depression and is worsened by exposure to psychosocial work stressors.

DESIGN

Longitudinal cohort study with surveys administered at baseline, 6, 12, and 18 months.

SETTING

Recruitment in primary care offices.

SUBJECTS

A total of 14,268 were screened; 286 depressed, employed adults (18-62 years) and 193 controls were enrolled.

MEASURES

At-work limitations (presenteeism) and absenteeism were measured with the Work Limitations Questionnaire (WLQ) and WLQ Work Absence Module, respectively. Work stressors were assessed using a modified version of the Job Content Questionnaire.

ANALYSIS

Univariate and multivariate tests assessed the degree to which at-work limitations were related to depression and/or stressful work.

RESULTS

Presenteeism and absenteeism were significantly worse for the depression group at each time point (p < or = .001). In cross-sectional models, presenteeism was associated with more severe depression symptoms, poorer general physical health, psychologically demanding work, the interaction ofpsychologically demanding work with depression, and less job control (r2 range = .33-.54). Absences were explained by depression symptom severity and poorer general physical health but not work stressors (r2 = .19). Because of minimal change in the work stressors, their longitudinal effects on outcomes were mostly nonsignificant.

CONCLUSION

This study found that depression symptoms are related to work absences and impaired work performance, and results partly confirmed that work stressors add to this impact. Results suggest that workers with depression may benefit from care involving medical and vocational interventions.

Marketing depression care management to employers: design of a randomized controlled trial

Background

Randomized trials demonstrate that depression care management can improve clinical and work outcomes sufficiently for selected employers to realize a return on investment. Employers can now purchase depression products that provide depression care management, defined as employee screening, education, monitoring, and clinician feedback for all depressed employees. We developed an intervention to encourage employers to purchase a depression product that offers the type, intensity, and duration of care management shown to improve clinical and work outcomes.

Methods

In a randomized controlled trial conducted with 360 employers of 30 regional business coalitions, the research team proposes to compare the impact of a value-based marketing intervention to usual-care marketing on employer purchase of depression products. The study will also identify mediators and organizational-level moderators of intervention impact. Employers randomized to the value-based condition receive a presentation encouraging them to purchase depression products scientifically shown to benefit the employee and the employer. Employers randomized to the usual-care condition receive a presentation encouraging them to monitor and improve quality indicators for outpatient depression treatment. Because previous research demonstrates that the usual-care intervention will have little to no impact on employer purchasing, depression product purchasing rates in the usual-care condition capture vendor efforts to market depression products to employers in both conditions while the value-based intervention is being conducted. Employers in both conditions are also provided free technical assistance to undertake the actions each presentation encourages. The research team will use intent-to-treat models of all available data to evaluate intervention impact on the purchase of depression products using a cumulative incidence analysis of 12- and 24-month data.

Discussion

By addressing the 'value to whom?' question, the study advances knowledge about one of the most pivotal problems in the translation of evidence-based care to 'real world' settings: whether purchasers can be influenced to buy healthcare products on the basis of value and not exclusively on the basis of cost. If value-based marketing increases depression product purchase rates over usual care, this study will provide encouragement to market new healthcare products on the basis of the product's value to the purchaser as well as the recipient of care.

Exploring productivity outcomes from a brief intervention for at-risk drinking in an employee assistance program

Brief intervention (BI) research has traditionally examined alcohol and drug use outcomes; however it is unknown whether BIs can also impact on-the-job productivity. This exploratory study examines changes in workplace productivity and related costs for clients receiving a BI for at-risk drinking in the employee assistance program (EAP). Participants were 44 clients attending the EAP for behavioral health concerns, screened for at-risk drinking, assigned to BI+Usual Care (n=25) or UC alone (n=19), and who completed 3-month follow-up. Absenteeism, presenteeism, and productivity costs were derived as outcomes. At follow-up, participants in the BI+UC group had improved productivity when at work (presenteeism) compared to the UC group. The estimated cost savings from improved productivity for the BI+UC group was $1200 per client over the UC group. Groups did not differ by absenteeism (missed days of work). Preliminary evidence suggests the broad impact BIs may have. Implications for future BI research are discussed.

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.

Mental health problems and help-seeking behavior among college students

Mental disorders are as prevalent among college students as same-aged non-students, and these disorders appear to be increasing in number and severity. The purpose of this report is to review the research literature on college student mental health, while also drawing comparisons to the parallel literature on the broader adolescent and young adult populations.

A new clinical rating scale for work absence and productivity: validation in patients with major depressive disorder

BACKGROUND

The prevalence of major depressive disorder (MDD) is highest in working age people and depression causes significant impairment in occupational functioning. Work productivity and work absence should be incorporated into clinical assessments but currently available scales may not be optimized for clinical use. This study seeks to validate the Lam Employment Absence and Productivity Scale (LEAPS), a 10-item self-report questionnaire that takes 3-5 minutes to complete.

METHODS

The study sample consisted of consecutive patients attending a Mood Disorders outpatient clinic who were in full- or part-time paid work. All patients met DSM-IV criteria for MDD and completed during their intake assessment the LEAPS, the self-rated version of the Quick Inventory for Depressive Symptomatology (QIDS-SR), the Sheehan Disability Scale (SDS) and the Health and Work Performance Questionnaire (HPQ). Standard psychometric analyses for validation were conducted.

RESULTS

A total of 234 patients with MDD completed the assessments. The LEAPS displayed excellent internal consistency as assessed by Cronbach's alpha of 0.89. External validity was assessed by comparing the LEAPS to the other clinical and work functioning scales. The LEAPS total score was significantly correlated with the SDS work disability score (r = 0.63, p < 0.01) and the Global Work Performance rating from the HPQ (r = -0.79, p < 0.01). The LEAPS total score also increased with greater depression severity.

CONCLUSION

The LEAPS displays good internal and external validity in a population of patients with MDD attending an outpatient clinic, which suggests that it may be a clinically useful tool to assess and monitor work functioning and productivity in depressed patients.

Comprehensive self-management for irritable bowel syndrome: randomized trial of in-person vs. combined in-person and telephone sessions

OBJECTIVES

Psychological and behavioral therapies are being increasingly used for symptom management in patients with irritable bowel syndrome (IBS). The aims of this study were to compare two delivery modes for a comprehensive self-management (CSM) intervention, primarily by telephone vs. entirely in person, and to compare each with usual care (UC).

METHODS

Adults with IBS were recruited through community advertisement. Subjects (N=188) were randomly assigned to three groups: one in which all nine weekly CSM sessions were delivered in person, one in which six of the nine sessions were conducted over telephone, and one in which subjects received UC. Primary outcome measures were a gastrointestinal (GI) symptom score based on six symptoms from a daily diary and disease-specific quality of life (QOL). These and other outcomes were assessed at baseline and at 3, 6, and 12 months after randomization. Mixed model analyses tested for differences between the three groups in each outcome variable at the three follow-up occasions, controlling for the baseline level of each outcome.

RESULTS

Both GI symptom score and QOL showed significantly greater improvement in the two CSM groups than in the UC group (P<0.001), with the magnitude of this difference being quite similar for the three follow-up time points. The two CSM groups experienced a very similar degree of improvement, and there were no statistically significant differences between the two.

CONCLUSIONS

A CSM program is efficacious whether delivered primarily by telephone or totally in person, and there is no evidence that replacing six of the in-person sessions by telephone sessions reduces the efficacy of the intervention.

Content comparison of worker productivity questionnaires in arthritis and musculoskeletal conditions using the International Classification of Functioning, Disability, and Health framework

BACKGROUND

Worker productivity outcome is essential in examining the rehabilitation of workers with arthritis and other musculoskeletal conditions. There is great variation in the contents of worker productivity questionnaires. The International Classification of Functioning Disability and Health (ICF) offers the possibility to serve as a reference to describe and compare the contents of these questionnaires.

METHODS

A literature review identified published self-report worker productivity questionnaires. All meaningful concepts were identified and linked to the corresponding ICF category according to established rules.

RESULTS

Eighteen questionnaires were identified which contained a total of 519 meaningful concepts and which were linked to 64 unique 2nd level ICF categories. All questionnaires addressed Activities and Participation, thirteen (72%) addressed Body Functions, seven (39%) addressed Environmental Factors, seven (39%) addressed Personal Factors and only one questionnaire (6%) for Body Structures component. Overall, Work Role Functioning (WRF) questionnaire addressed the most number of different categories while Quantity and Quality method contained only one ICF category. The Rheumatoid Arthritis-Work Instability Scale had the highest number of categories for Body Functions, the Work Activity Limitations Scale and WRF had the most number of categories for Activities and Participation. The Health and Labour Questionnaire had the highest number of categories referring to unpaid work participation. The Health and Work Questionnaire was the only that included contextualization of both Environmental and Personal Factors.

CONCLUSION

Self-report worker productivity questionnaires differed largely in their contents. This content analysis study could guide us in selecting an appropriate questionnaire for a specific study question.

Wishing upon a STAR*D: the promise of ideal depression care by primary care providers

The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial found that after initial treatment, depressed patients treated in primary care settings had the same or slightly better outcomes than those treated in specialty care settings. The authors describe challenges to using the STAR*D approach and protocols in usual primary care settings. These include inadequate availability of appointments, insufficient resources for care management and treatment monitoring, and lack of payment to primary care providers for providing mental health care. Substantial reengineering of payment and delivery systems is needed in order for the STAR*D approach to be viable in primary care clinics.

Packages of care for depression in low- and middle-income countries

In the first in a series of six articles on packages of care for mental disorders in low- and middle-income countries, Neerja Chowdary and colleagues discuss the treatment of depression.

Factors Associated with Incidental Sickness Absence among Employees in One Health Care System

Purpose.

Assess the association of taking incidental sickness absence with health risks and health status.

Design.

Observational.

Setting.

One Midwest health care system.

Subjects.

Individuals who were employed for 2 years (2006–2007) and had completed at least one health risk appraisal (HRA) in 2007 (N = 3790).

Measures.

Outcomes were any incidental sickness absence and absence duration in 2007 measured by an absence tracking system. Health risks and health status were estimated by HRAs. Program participation was captured using 7-year HRA data and 5-year wellness data.

Analysis.

Multivariate, binary logistic regression for the probability of taking any absence day among the overall population as well as four demographic subgroups; proportional odds model for the probability of taking more absence days.

Results.

Different patterns were observed in association with taking incidental sickness absence among age and gender subgroups. Among the overall population, three health risks (smoking overweight, and use of medication for relaxation) were positively associated with taking absence (at least p <. 05 for all three health risks). Participation in a wellness program for more years was also associated with a less likelihood of taking absence (odds ratio, .72; p = .002). Results from the proportional odds model were consistent with results from the binary logistic regression.

Conclusion.

Sickness absence is an important productivity concern of employers. Employers may implement early interventions to focus on preventable causes. Special interventions may target absence-causing risks such as smoking behavior and excess body weight. Study limitation includes a lack of measures for psychosocial work environment.

When is pharmacogenetic testing for antidepressant response ready for the clinic? A cost-effectiveness analysis based on data from the STAR*D study

The potential of personalized medicine to transform the treatment of mood disorders has been widely touted in psychiatry, but has not been quantified. We estimated the costs and benefits of a putative pharmacogenetic test for antidepressant response in the treatment of major depressive disorder (MDD) from the societal perspective. Specifically, we performed cost-effectiveness analyses using state-transition probability models incorporating probabilities from the multicenter STAR*D effectiveness study of MDD. Costs and quality-adjusted life years (QALYs) were compared for sequential antidepressant trials, with or without guidance from a pharmacogenetic test for differential response to selective serotonin reuptake inhibitors (SSRIs). Likely SSRI responders received an SSRI, whereas likely nonresponders received the norepinephrine/dopamine reuptake inhibitor bupropion. For a 40-year old with MDD, applying the pharmacogenetic test and using the non-SSRI bupropion for those at higher risk for nonresponse cost $93,520 per additional QALY compared with treating all patients with an SSRI first and switching sequentially in the case of nonremission. Cost per QALY dropped below $50,000 for tests with remission rate ratios as low as 1.5, corresponding to odds ratios approximately 1.8-2.0. Tests for differential antidepressant response could thus become cost effective under certain circumstances. These circumstances, particularly availability of alternative treatment strategies and test effect sizes, can be estimated and should be considered before these tests are broadly applied in clinical settings.

Effectiveness of a depression disease management program in improving depression and work function--a pilot study

OBJECTIVE

We examined whether there were differences in depression and work function outcomes among primary care and specialty mental health patients treated by the Michigan Depression Outreach and Collaborative Care (M-DOCC), a depression care management program, developed by the University of Michigan Depression Center. In addition, we examined the relationship between depressive symptoms and workplace functioning among M-DOCC enrollees over time.

METHOD

We used mixed model and logistic regression analyses.

RESULTS

Despite baseline differences in patient characteristics between primary care and specialty care patients, the location of treatment setting was not a significant predictor of depression or work function outcomes over time among patients enrolled in a depression care management program. Patients in both treatment settings showed significant decreases in depressive and functional impairment over time, with improvements in these symptoms occurring concurrently. Patients with greater case severity were less likely to demonstrate depression and work function improvements over time, and more severe side effects were associated with fewer depression symptom improvements over time.

CONCLUSIONS

Both depression and work function outcomes improved over time among patients enrolled in a depression care management program, and this improvement did not differ based on whether a patient was treated in a primary or specialty care setting.

Improving mental health treatments through comparative effectiveness research

There is a pressing need for comparative effectiveness research to improve mental health treatments. Although U.S. mental health spending has increased dramatically, mainly because of the rapid adoption of newer psychotropic medications, fewer than a quarter of people with serious mental illnesses receive appropriate care. Because of a general lack of information on the relative effectiveness of different treatments, payers are uncertain about the value of current spending, which in turn may deter new investments to reduce unmet need. We use several recent comparative effectiveness trials to illustrate the potential value of such research for improving practice and policy.

Psychosocial work environment and depressive symptoms among US workers: comparing working poor and working non-poor

BACKGROUND

The psychosocial work environment has been associated with mental health outcomes; however, little research has examined this relationship for low-wage workers. The purpose of this study was to investigate the relationship between psychosocial job characteristics and depressive symptoms for US workers using an expanded model of job quality.

METHODS

Data were from the 2002 National Study of the Changing Workforce, a nationally representative study of wage and salaried workers in the US. Working poor was defined as households earning <250% of the federal poverty threshold.

RESULTS

Multivariate logistic regression models show for working poor employees, job insecurity was the single significant correlate of depressive symptoms after controlling for other demographic and work environment variables. For working non-poor employees, high psychological demands and low supervisor and coworker support were associated with depressive symptoms.

CONCLUSIONS

Findings suggest all jobs do not equally affect employees' depressive symptoms. Implications for research that may improve the mental health of the working poor in the US are presented.

Promoting mental health recovery after hurricanes Katrina and Rita: what can be done at what cost

CONTEXT

Concerns about mental health recovery persist after the 2005 Gulf storms. We propose a recovery model and estimate costs and outcomes.

OBJECTIVE

To estimate the costs and outcomes of enhanced mental health response to large-scale disasters using the 2005 Gulf storms as a case study.

DESIGN

Decision analysis using state-transition Markov models for 6-month periods from 7 to 30 months after disasters. Simulated movements between health states were based on probabilities drawn from the clinical literature and expert input.

SETTING

A total of 117 counties/parishes across Louisiana, Mississippi, Alabama, and Texas that the Federal Emergency Management Agency designated as eligible for individual relief following hurricanes Katrina and Rita.

PARTICIPANTS

Hypothetical cohort, based on the size and characteristics of the population affected by the Gulf storms. Intervention Enhanced mental health care consisting of evidence-based screening, assessment, treatment, and care coordination.

MAIN OUTCOME MEASURES

Morbidity in 6-month episodes of mild/moderate or severe mental health problems through 30 months after the disasters; units of service (eg, office visits, prescriptions, hospital nights); intervention costs; and use of human resources.

RESULTS

Full implementation would cost $1133 per capita, or more than $12.5 billion for the affected population, and yield 94.8% to 96.1% recovered by 30 months, but exceed available provider capacity. Partial implementation would lower costs and recovery proportionately.

CONCLUSIONS

Evidence-based mental health response is feasible, but requires targeted resources, increased provider capacity, and advanced planning.

Guideline-based care of common mental disorders by occupational physicians (CO-OP study): a randomized controlled trial

OBJECTIVE

To evaluate the effectiveness of guideline-based care (GBC) of workers with mental health problems, which promotes counseling by the occupational physician (OP) facilitating return to work (RTW).

METHODS

In a randomized controlled trial with police workers on sick leave due to mental health problems (n = 240), trained OPs delivered GBC in the intervention group. Time to RTW and recurrences during 1-year follow-up, analyzed using Cox proportional hazards models, were compared with usual care (UC) with easy access to a psychologist.

RESULTS

GBC by OPs did not result in earlier RTW than UC. Subgroup analysis showed a small effect in favor of GBC for workers with administrative functions and/or "minor" stress-related symptoms.

CONCLUSIONS

GBC did not differ in RTW compared with UC, but may be beneficial for the majority of workers with minor stress-related disorders.

Policy implications of the 2007 Australian National Survey of Mental Health and Wellbeing

OBJECTIVES

To describe some of the policy implications of the Australian National Survey of Mental Health and Wellbeing.

METHODS

A review of the initial findings from the Survey published by the Australian Bureau of Statistics and the five papers in this issue of the Journal, was done.

RESULTS

Mental disorders are highly prevalent with the prevalence essentially unchanged since Australia's 1997 mental health survey. Mental disorders are often comorbid with each other and with physical disorders. Despite the disability they cause, most people with disorders do not seek treatment. This is largely because they do not perceive a need for treatment.

CONCLUSIONS

National epidemiological surveys are important for service planning. They are especially important in gaining an understanding of the population not accessing services. Innovative strategies, including action on mental health literacy, will be necessary to increase the treatment rates for common mental disorders.

Optimized antidepressant therapy and pain self-management in primary care patients with depression and musculoskeletal pain: a randomized controlled trial

CONTEXT

Pain and depression are the most common physical and psychological symptoms in primary care, respectively. Moreover, they co-occur 30% to 50% of the time and have adverse effects on quality of life, disability, and health care costs.

OBJECTIVE

To determine if a combined pharmacological and behavioral intervention improves both depression and pain in primary care patients with musculoskeletal pain and comorbid depression.

DESIGN, SETTING, AND PATIENTS

Randomized controlled trial (Stepped Care for Affective Disorders and Musculoskeletal Pain [SCAMP]) conducted at 6 community-based clinics and 5 Veterans Affairs general medicine clinics in Indianapolis, Indiana. Recruitment occurred from January 2005 to June 2007 and follow-up concluded in June 2008. The 250 patients had low back, hip, or knee pain for 3 months or longer and at least moderate depression severity (Patient Health Questionnaire 9 score > or = 10).

INTERVENTION

Patients were randomly assigned to the intervention (n = 123) or to usual care (n = 127). The intervention consisted of 12 weeks of optimized antidepressant therapy (step 1) followed by 6 sessions of a pain self-management program over 12 weeks (step 2), and a continuation phase of therapy for 6 months (step 3).

MAIN OUTCOME MEASURES

Depression (20-item Hopkins Symptom Checklist), pain severity and interference (Brief Pain Inventory), and global improvement in pain at 12 months.

RESULTS

At 12 months, 46 of the 123 intervention patients (37.4%) had a 50% or greater reduction in depression severity from baseline compared with 21 of 127 usual care patients (16.5%) (relative risk [RR], 2.3; 95% confidence interval [CI], 1.5-3.2), corresponding to a much lower number of patients with major depression (50 [40.7%] vs 87 [68.5%], respectively; RR, 0.6 [95% CI, 0.4-0.8]). Also, a clinically significant (> or = 30%) reduction in pain was much more likely in intervention patients (51 intervention patients [41.5%] vs 22 usual care patients [17.3%]; RR, 2.4 [95% CI, 1.6-3.2]), as was global improvement in pain (58 [47.2%] vs 16 [12.6%], respectively; RR, 3.7 [95% CI, 2.3-6.1]). More intervention patients also experienced benefits in terms of the primary outcome, which was a combined improvement in both depression and pain (32 intervention patients [26.0%] vs 10 usual care patients [7.9%]; RR, 3.3 [95% CI, 1.8-5.4]).

CONCLUSION

Optimized antidepressant therapy followed by a pain self-management program resulted in substantial improvement in depression as well as moderate reductions in pain severity and disability.

The impact of mental health symptoms on heavy goods vehicle drivers' performance

High levels of psychological distress in fulltime employees are prevalent (4.5% per month). Symptoms of impaired mental health include difficulties with attention, concentration, motivation, decision-making, visuo-motor control, and psychomotor reaction times. There is limited research on the impact these symptoms have on heavy goods vehicle (HGV) drivers' performance. In this study 1324 HGV drivers were surveyed using the Depression, Anxiety, Stress Scale (DASS) and the Health and Performance at Work Questionnaire (HPQ). Depression, anxiety and stress had little effect on driver absenteeism rates or self-rated driving performance. However, severe (1.5% of drivers) and very severe (1.8% of drivers) depression was associated with an increased odds ratio (OR=4.5 and 5.0, respectively) for being involved in an accident or near miss in the past 28 days. This odd ratio is akin to driving with a blood alcohol content of about 0.08%. Given the number of HGV vehicles and the prevalence of depression this equates to 10,950 HGV drivers with an increased statistical risk of an accident or near miss. As the impact of HGV accidents is potentially large, including loss of life, it would be sensible to extend the research findings here into an action plan.

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.

A blueprint for pharmacy benefit managers to increase value

Pharmacy benefit managers (PBMs) have a unique opportunity to promote health and generate value in the healthcare system. Today, PBMs are largely evaluated on their ability to control costs rather than improve health. Pharmacy benefit managers should be evaluated along 3 dimensions in which they can increase value: (1) use of cost-effective medications, (2) timely initiation of appropriate medication therapy, and (3) adherence to that therapy. Value creation requires the development of integrated data systems, stronger partnerships with patients and physicians, and improved measurement and reporting of results. Incentives for PBMs to promote value should drive innovation and improve health outcomes.

Disability from depression: the public health challenge to primary care

Epidemiologists have identified that depression will soon be the leading cause of disability throughout the world. To inform public health campaigns to reduce this problem, this paper summarizes current scientific knowledge about optimizing the potential of primary care settings to reduce disability by providing effective treatment for depression. To meet this challenge, primary care practices need to be re-engineered: 1) to conduct systematic screening programs to identify depressed patients, 2) to provide depressed patients initial evidence-based treatment, and 3) to monitor treatment adherence and symptom response in treated patients over 2 years. While additional research is needed in developing countries, preliminary evidence indicates that primary care practices re-engineered to improve depression management can make a substantial contribution to reducing depression-associated disability.

The cost and impact of health conditions on presenteeism to employers: a review of the literature

Employers are becoming concerned with the costs of presenteeism in addition to the healthcare and absenteeism costs that have traditionally been explored. But what is the true impact of health conditions in terms of on-the-job productivity? This article examines the literature to assess the magnitude of presenteeism costs relative to total costs of a variety of health conditions. Searches of MEDLINE, CINAHL and PubMed were conducted in July 2008, with no starting date limitation, using 'presenteeism' or 'work limitations' as keywords. Publications on a variety of health conditions were located and included if they assessed the total healthcare and productivity cost of one or more health conditions. Literature on presenteeism has investigated its link with a large number of health conditions ranging from allergies to irritable bowel syndrome. The cost of presenteeism relative to the total cost varies by condition. In some cases (such as allergies or migraine headaches), the cost of presenteeism is much larger than the direct healthcare cost, while in other cases (such as hypertension or cancer), healthcare is the larger component. Many more studies have examined the impact of pharmaceutical treatment on certain medical conditions and the resulting improvement in on-the-job productivity. Based on the research reviewed here, health conditions are associated with on-the-job productivity losses and presenteeism is a major component of the total employer cost of those conditions, although the exact dollar amount cannot be determined at this time. Interventions, including the appropriate use of pharmaceutical agents, may be helpful in improving the productivity of employees with certain conditions.

The prevalence and workplace costs of adult attention deficit hyperactivity disorder in a large manufacturing firm

BACKGROUND

Little is known about the effects of adult attention deficit hyperactivity disorder (ADHD) on work performance or accidents-injuries.MethodA survey was administered in 2005 and 2006 to employees of a large manufacturing firm to assess the prevalence and correlates of adult ADHD. Respondents (4,140 in 2005, 4,423 in 2006, including 2,656 in both surveys) represented 35-38% of the workforce. ADHD was assessed with the World Health Organization (WHO) Adult ADHD Self-Report Scale (ASRS), a validated screening scale for DSM-IV adult ADHD. Sickness absence, work performance and workplace accidents-injuries were assessed with the WHO Health and Work Performance Questionnaire (HPQ).

RESULTS

The estimated current prevalence (standard error) of DSM-IV ADHD was 1.9% (0.4). ADHD was associated with a 4-5% reduction in work performance (chi12=9.1, p=0.001), a 2.1 relative-odds of sickness absence (chi12=6.2, p=0.013), and a 2.0 relative-odds of workplace accidents-injuries (chi12=5.1, p=0.024). The human capital value (standard error) of the lost work performance associated with ADHD totaled USD 4,336 (676) per worker with ADHD in the year before interview. No data were available to monetize other workplace costs of accidents-injuries (e.g. destruction of equipment). Only a small minority of workers with ADHD were in treatment.

CONCLUSIONS

Adult ADHD is a significantly impairing condition among workers. Given the low rate of treatment and high human capital costs, in conjunction with evidence from controlled trials that treatment can reduce ADHD-related impairments, ADHD would seem to be a good candidate for workplace trials that evaluate treatment cost-effectiveness from the employer's perspective.

Employee absenteeism measures reflecting current work practices may be instrumental in a re-evaluation of the relationship between psychological distress/mental health and absenteeism

Absenteeism rates are the cornerstone metrics guiding corporate policy for health care investment in employees. However, traditional absenteeism measures do not reflect the contemporary workplace milieu. It is accepted practice that employees work evenings or weekends to makeup time. Using a hours-based absenteeism measure, that accounts for time made-up as well as time lost, this paper evaluates the impact of psychological distress on employee absenteeism.Psychological distress and absenteeism data were collected from 54,264 full-time employees. Consistent with traditional approaches, employees indicated how many days they were absent. Hours based absenteeism was formulated from the ratio of how many hours the employees worked and how many hours were they expected to work in the past seven-days.Concordant with previous concinnous evidence, traditional absenteeism computation indicated that elevated psychological distress is associated with increasing absenteeism. Using the hours-based method psychological distress did not significantly influence absenteeism.Traditional calculations of absenteeism do not reflect the current work practices of the majority of employees. Employees with psychological distress may take time off work but it appears that they make up for lost time possibly to stay up to speed with task driven occupations and avoid performance review.

The WHO World Mental Health (WMH) Surveys

The paper presents an overview of the WHO World Mental Health (WMH) Survey Initiative and summarizes recent WMH results regarding the prevalence and societal costs of mental disorders. The WMH surveys are representative community surveys that were carried out in 28 countries throughout the world aimed at providing information to mental health policy makers about the prevalence, burden, and unmet need for treatment of common mental disorders. Results show that mental disorders are commonly occurring in all participating countries. The inter-quartile range (IQR: 25(th)-75(th) percentiles) of lifetime DSM-IV disorder prevalence estimates (combining anxiety, mood, disruptive behavior, and substance disorders) is 18.1-36.1%. The IQR of 12-month prevalence estimates is 9.8-19.1%. Analysis of age-of-onset reports shows that many mental disorders begin in childhood-adolescence and have significant adverse effects on subsequent role transitions. Adult mental disorders are found in the WMH data to be associated with high levels of role impairment. Despite this burden, the majority of mental disorders go untreated. Although these results suggest that expansion of treatment could be cost-effective from both the employer perspective and the societal perspective, treatment effectiveness trials are needed to confirm this suspicion. The WMH results regarding impairments are being used to target several such interventions.

The global burden of mental disorders: an update from the WHO World Mental Health (WMH) surveys

AIMS

The paper reviews recent findings from the WHO World Mental Health (WMH) surveys on the global burden of mental disorders.

METHODS

The WMH surveys are representative community surveys in 28 countries throughout the world aimed at providing information to mental health policy makers about the prevalence, distribution, burden, and unmet need for treatment of common mental disorders.

RESULTS

The first 17 WMH surveys show that mental disorders are commonly occurring in all participating countries. The inter-quartile range (IQR: 25th-75th percentiles) of lifetime DSM-IV disorder prevalence estimates (combining anxiety, mood, externalizing, and substance use disorders) is 18.1-36.1%. The IQR of 12-month prevalence estimates is 9.8-19.1%. Prevalence estimates of 12-month Serious Mental Illness (SMI) are 4-6.8% in half the countries, 2.3-3.6% in one-fourth, and 0.8-1.9% in one-fourth. Many mental disorders begin in childhood-adolescence and have significant adverse effects on subsequent role transitions in the WMH data. Adult mental disorders are found to be associated with such high role impairment in the WMH data that available clinical interventions could have positive cost-effectiveness ratios.

CONCLUSIONS

Mental disorders are commonly occurring and often seriously impairing in many countries throughout the world. Expansion of treatment could be cost-effective from both employer and societal perspectives.

Health plans' disease management programs: extending across the medical and behavioral health spectrum?

Although the disease management industry has expanded rapidly, there is little nationally representative data regarding medical and behavioral health disease management programs at the health plan level. National estimates from a survey of private health plans indicate that 90% of health plan products offered disease management for general medical conditions such as diabetes but only 37% had depression programs. The frequency of specific depression disease management activities varied widely. Program adoption was significantly related to product type and behavioral health contracting. In health plans, disease management has penetrated more slowly into behavioral health and depression program characteristics are highly variable.

Making the business case for enhanced depression care: the National Institute of Mental Health-harvard Work Outcomes Research and Cost-effectiveness Study

OBJECTIVE

Explore the business case for enhanced depression care and establish a return on investment rationale for increased organizational involvement by employer-purchasers.

METHOD

Literature review, focused on the National Institute of Mental Health-sponsored Work Outcomes Research and Cost-effectiveness Study.

RESULTS

This randomized controlled trial compared telephone outreach, care management, and optional psychotherapy to usual care among depressed workers in large national corporations. By 12 months, the intervention significantly improved depression outcomes, work retention, and hours worked among the employed.

CONCLUSION

Results of the Work Outcomes Research and Cost-effectiveness Study trial and other studies suggest that enhanced depression care programs represent a human capital investment opportunity for employers.

Challenges and opportunities for preventing depression in the workplace: a review of the evidence supporting workplace factors and interventions

OBJECTIVE

To explore the literature regarding prevention of depression in the workplace.

METHOD

Literature review of what the author believes are seminal articles highlighting workplace factors and interventions in preventing depression in the workplace.

RESULTS

Employees can help prevent depression by building protective factors such as better coping and stress management skills. Employees may be candidates for depression screening if they have certain risk factors such as performance concerns. Organizational interventions such as improving mental health literacy and focusing on work-life balance may help prevent depression in the workplace but deserve further study.

CONCLUSION

A strategy to prevent depression in the workplace can include developing individual resilience, screening high-risk individuals and reducing that risk, improving organizational literacy, and integrating workplace and health care systems to allow access to proactive quality interventions.

The effects of quality improvement for depression in primary care at nine years: results from a randomized, controlled group-level trial

OBJECTIVE

To examine 9-year outcomes of implementation of short-term quality improvement (QI) programs for depression in primary care.

DATA SOURCES

Depressed primary care patients from six U.S. health care organizations.

STUDY DESIGN

Group-level, randomized controlled trial.

DATA COLLECTION

Patients were randomly assigned to short-term QI programs supporting education and resources for medication management (QI-Meds) or access to evidence-based psychotherapy (QI-Therapy); and usual care (UC). Of 1,088 eligible patients, 805 (74 percent) completed 9-year follow-up; results were extrapolated to 1,269 initially enrolled and living. Outcomes were psychological well-being (Mental Health Inventory, five-item version [MHI5]), unmet need, services use, and intermediate outcomes.

PRINCIPAL FINDINGS

At 9 years, there were no overall intervention status effects on MHI5 or unmet need (largest F (2,41)=2.34, p=.11), but relative to UC, QI-Meds worsened MHI5, reduced effectiveness of coping and among whites lowered tangible social support (smallest t(42)=2.02, p=.05). The interventions reduced outpatient visits and increased perceived barriers to care among whites, but reduced attitudinal barriers due to racial discrimination and other factors among minorities (smallest F (2,41)=3.89, p=.03).

CONCLUSIONS

Main intervention effects were over but the results suggest some unintended negative consequences at 9 years particularly for the medication-resource intervention and shifts to greater perceived barriers among whites yet reduced attitudinal barriers among minorities.

Individual and societal effects of mental disorders on earnings in the United States: results from the national comorbidity survey replication

OBJECTIVE

The purpose of this report was to update previous estimates of the association between mental disorders and earnings. Current estimates for 2002 are based on data from the National Comorbidity Survey Replication (NCS-R).

METHOD

The NCS-R is a nationally representative survey of the U.S. household population that was administered from 2001 to 2003. Following the same basic approach as prior studies, with some modifications to improve model fitting, the authors predicted personal earnings in the 12 months before interview from information about 12-month and lifetime DSM-IV mental disorders among respondents ages 18-64, controlling for sociodemographic variables and substance use disorders. The authors used conventional demographic rate standardization methods to distinguish predictive effects of mental disorders on amount earned by persons with earnings from predictive effects on probability of having any earnings.

RESULTS

A DSM-IV serious mental illness in the preceding 12 months significantly predicted reduced earnings. Other 12-month and lifetime DSM-IV/CIDI mental disorders did not. Respondents with serious mental illness had 12-month earnings averaging $16,306 less than other respondents with the same values for control variables ($26,435 among men, $9,302 among women), for a societal-level total of $193.2 billion. Of this total, 75.4% was due to reduced earnings among mentally ill persons with any earnings (79.6% men, 69.6% women). The remaining 24.6% was due to reduced probability of having any earnings.

CONCLUSIONS

These results add to a growing body of evidence that mental disorders are associated with substantial societal-level impairments that should be taken into consideration when making decisions about the allocation of treatment and research resources.

Collaborative mental health and primary care for bipolar disorder

This article discusses the use of integrated care models, in particular, collaborative care, in the treatment of bipolar disorder. Dr. Williams first discusses how care delivered via a collaboration between primary care and psychiatric providers has the potential to improve both mental health and general medical outcomes for patients with bipolar disorder. He describes promising findings from studies of the use of collaborative care in the treatment of depression, an area where this model has received the most study. Dr. Williams then discusses how such collaborative care models might best be implemented in the treatment of bipolar disorder. In the second half of the article, Dr. Manning focuses on five key issues that are an especially appropriate focus for collaborative care for bipolar disorder and for which the STAndards for BipoLar Excellence (STABLE) Project developed quality improvement performance measures: assessment for risk of suicide, assessment for substance use/abuse, monitoring for extrapyramidal symptoms, monitoring of metabolic parameters (e.g., monitoring for weight gain, hyperglycemia, hyperlipidemia), and provision of bipolar-specific psychoeducation.
