The effect of a primary care practice-based depression intervention on mortality in older adults: a randomized trial

Ambulatory Care Utilization Among Medicare Beneficiaries with Depression

The association between depression and ambulatory care utilization is unclear. The authors sought to determine the association between untreated depression and ambulatory care utilization, including the extent to which care is fragmented, or spread across providers. The authors conducted a longitudinal study using data from the nationwide REasons for Geographic and Racial Differences in Stroke study linked to Medicare fee-for-service claims (N = 1412). They categorized participants into three study groups, based on self-reported depressive symptoms (Center for Epidemiological Studies Depression Scale score ≥ 4) and a medication inventory for antidepressants: Symptomatic Untreated (SU), Symptomatic Treated (ST), and Asymptomatic Treated (AT). The authors used descriptive statistics to characterize ambulatory care patterns by study group. They determined the association between the study group and fragmentation score (with high fragmentation defined as a reversed Bice-Boxerman Index ≥ 0.85) using multivariable logistic regression. All groups had similar numbers of primary care visits, but the SU group had the fewest specialist visits. The SU group had the lowest proportion of participants who received care from a psychiatrist (3.4% vs. 10.7% for ST and 11.9% for AT, pairwise P-values < 0.001). The SU group was the least likely to have highly fragmented care (adjusted odds ratio 0.68; 95% confidence interval 0.48, 0.95, compared with the ST group). These results suggest that older adults with untreated depression are not engaged in excess care-seeking behaviors. Rather, the results suggest undertreatment of depression in primary care and underutilization of psychiatric care.

Protocol for a randomized controlled trial of brief behavioral activation among older adult cancer survivors

INTRODUCTION

As many as 35% of older adult cancer survivors (OACS; i.e., ≥65 years old) have clinically significant depression. OACS often experience fatigue, mild cognitive impairment, and increased medical comorbidities post-cancer that make them susceptible to depression. Behavioral activation (BA) is an empirically supported depression treatment in geriatric psychiatry that guides individuals to reengage in pleasurable and rewarding activities and has great potential for addressing the needs of OACS. This manuscript presents the protocol for a pilot randomized controlled trial (RCT) testing the efficacy of a brief BA intervention adapted to address the needs of OACS (BBA-OACS) by telephone and videoconference delivery.

MATERIALS AND METHODS

An RCT will be conducted at Memorial Sloan Kettering Cancer Center (MSK) in New York City. Participants will be randomized to either BA as a target intervention or supportive psychotherapy (SP) as a standard of care control intervention for outpatient oncology. The target intervention includes 10 weekly sessions of BA consisting of psychoeducation about depression and the rationale for BA, life areas and values assessment, compilation of a list of enjoyable and important activities across values, activity scheduling, and self-monitoring of satisfaction and mood. The standard of care control intervention includes 10 weekly sessions of SP consisting of reassurance, guidance, encouragement, and support for patients with cancer. OACS who have a history of cancer, report elevated depressive symptoms, are fluent in English, and can communicate via telephone or videoconference will be recruited from the MSK Survivorship Clinics across all disease types. Seventy participants will be recruited for the study (10 training cases, 30 in each RCT arm). The primary aim is to evaluate implementation outcomes (i.e., acceptability, feasibility, and fidelity) of BA, relative to SP, for cancer survivorship. The secondary aim is to determine the preliminary effects of BA on depressive symptoms (primary outcome), anxiety, coping, and increased activity level (secondary outcomes) compared to SP. Participants will be asked to complete a set of three surveys pre- and post-intervention.

DISCUSSION

If successful, BBA-OACS would provide frontline clinicians with an accessible, evidence-based treatment for OACS. Future research will evaluate the efficacy of BA in a larger trial and its impact on depression and other healthcare outcomes.

TRIAL REGISTRATION

This study is registered under ClinicalTrials.gov (ID NCT05574127).

One-Year All-Cause Mortality and Delivery of the Collaborative Chronic Care Model in General Mental Health Clinics

OBJECTIVE

This study aimed to determine whether the evidence-based collaborative chronic care model (CCM) is associated with reduced all-cause mortality among adult patients treated in general mental health clinics.

METHODS

Data came from a stepped-wedge, cluster-randomized CCM implementation trial across nine U.S. Department of Veterans Affairs medical centers. Survival analysis was used to estimate the relative effect of the treatment (N=5,570) compared with a control group (N=46,443) over 1 year.

RESULTS

After adjustment for site-level and individual-level acute care utilization factors, analyses indicated that patients treated with the CCM experienced a reduction in all-cause mortality relative to patients in the control cohort (hazard ratio=0.76, 95% CI=0.60-0.95).

CONCLUSIONS

This study is the first in which CCM has been shown to reduce all-cause mortality for patients treated in general mental health clinics. Care delivery models should be considered part of efforts to reduce the life expectancy gap between individuals with psychiatric conditions and those without such conditions.

Adapting psychotherapy in collaborative care for treating opioid use disorder and co-occurring psychiatric conditions in primary care

INTRODUCTION

Opioid use disorder (OUD) and psychiatric conditions commonly co-occur yet are infrequently treated with evidence-based therapeutic approaches, resulting in poor outcomes. These conditions, separately, present challenges to treatment initiation, retention, and success. These challenges are compounded when individuals have OUD and psychiatric conditions.

METHOD

Recognizing the complex needs of these individuals, gaps in care, and the potential for primary care to bridge these gaps, we developed a psychotherapy program that integrates brief, evidence-based psychotherapies for substance use, depression, and anxiety, building on traditional elements of the Collaborative Care Model (CoCM). In this article, we describe this psychotherapy program in a primary care setting as part of a compendium of collaborative services.

RESULTS

Patients receive up to 12 sessions of evidence-based psychotherapy and case management based on a structured treatment manual that guides treatment via Motivational Enhancement; Cognitive Behavioral Therapies for depression, anxiety, and/or substance use disorder; and/or Behavioral Activation components.

DISCUSSION

Novel, integrated treatments are needed to advance service delivery for individuals with OUD and psychiatric conditions and these programs must be rigorously evaluated. We describe our team's efforts to test our psychotherapy program in a large primary care network as part of an ongoing three-arm randomized controlled trial.

Depression and Suicide Risk Screening: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

Importance

Depression is common and associated with substantial burden. Suicide rates have increased over the past decade, and both suicide attempts and deaths have devastating effects on individuals and families.

Objective

To review the benefits and harms of screening and treatment for depression and suicide risk and the accuracy of instruments to detect these conditions among primary care patients.

Data Sources

MEDLINE, PsychINFO, Cochrane library through September 7, 2022; references of existing reviews; ongoing surveillance for relevant literature through November 25, 2022.

Study Selection

English-language studies of screening or treatment compared with control conditions, or test accuracy of screening instruments (for depression, instruments were selected a priori; for suicide risk, all were included). Existing systematic reviews were used for treatment and test accuracy for depression.

Data Extraction and Synthesis

One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Findings were synthesized qualitatively, including reporting of meta-analysis results from existing systematic reviews; meta-analyses were conducted on original research when evidence was sufficient.

Main Outcomes and Measures

Depression outcomes; suicidal ideation, attempts, and deaths; sensitivity and specificity of screening tools.

Results

For depression, 105 studies were included: 32 original studies (N=385 607) and 73 systematic reviews (including ≈2138 studies [N ≈ 9.8 million]). Depression screening interventions, many of which included additional components beyond screening, were associated with a lower prevalence of depression or clinically important depressive symptomatology after 6 to 12 months (pooled odds ratio, 0.60 [95% CI, 0.50-0.73]; reported in 8 randomized clinical trials [n=10 244]; I2 = 0%). Several instruments demonstrated adequate test accuracy (eg, for the 9-item Patient Health Questionnaire at a cutoff of 10 or greater, the pooled sensitivity was 0.85 [95% CI, 0.79-0.89] and specificity was 0.85 [95% CI, 0.82-0.88]; reported in 47 studies [n = 11 234]). A large body of evidence supported benefits of psychological and pharmacologic treatment of depression. A pooled estimate from trials used for US Food and Drug Administration approval suggested a very small increase in the absolute risk of a suicide attempt with second-generation antidepressants (odds ratio, 1.53 [95% CI, 1.09-2.15]; n = 40 857; 0.7% of antidepressant users had a suicide attempt vs 0.3% of placebo users; median follow-up, 8 weeks). Twenty-seven studies (n = 24 826) addressed suicide risk. One randomized clinical trial (n=443) of a suicide risk screening intervention found no difference in suicidal ideation after 2 weeks between primary care patients who were and were not screened for suicide risk. Three studies of suicide risk test accuracy were included; none included replication of any instrument. The included suicide prevention studies generally did not demonstrate an improvement over usual care, which typically included specialty mental health treatment.

Conclusions and Relevance

Evidence supported depression screening in primary care settings, including during pregnancy and postpartum. There are numerous important gaps in the evidence for suicide risk screening in primary care settings.

Minimally Adequate Treatment for Depression and Anxiety Associated With Mortality in Primary Care Older Adults

OBJECTIVE

To assess the association between receipt of minimally adequate treatment (MAT) and mortality in a sample of community primary care older adults with depression and anxiety.

METHOD

The present study was conducted among a sample of 358 older adults ( ≥ 65 years old) with depression or an anxiety disorder recruited in primary care practices between 2011 and 2013. Participants agreed to link their health survey and administrative data for the 3 years preceding and following the baseline interview. Depression and anxiety disorders were based on self-reported symptoms aligned with DSM-5 criteria and physician diagnoses (International Classification of Diseases [ICD], 9^th and 10^th revisions). MAT was defined according to Canadian guidelines and include receipt of pharmacotherapy and ≥ 4 medical visits within 3 months or a number of psychotherapy sessions (individual, group, or family) over 12 months (depression: ≥8; anxiety disorders: ≥5 to 7). All-cause 3-year mortality was ascertained from the vital statistics death registry in Québec. Propensity score weighted regression analysis was conducted to assess the association between receipt of MAT and mortality adjusting for individual, clinical, and health system study factors.

RESULTS

Receipt of MAT was associated with a reduced risk of mortality (hazard ratio [HR]: 0.27; 95% confidence interval [95% CI], 0.12 to 0.62). Individual and clinical factors associated with increased mortality included older age, male sex, being single, low functional status, and increased physical disorders and cognitive functioning. Lifestyle factors associated with reduced and increased mortality included alcohol consumption and smoking, respectively. Health system factors such as perceived adequate number of visits to speak to the doctor about emotional problems and continuity of care were associated with reduced mortality.

CONCLUSION

The current study highlights the important role of primary care physicians in detecting and providing MAT for older adults with depression and anxiety, as this may have an effect on longevity.

Socioeconomic Factors Related to Prevalence, Severity, and Contact Coverage of Depression in Primary Health Care

Background

We determine factors related to the prevalence, severity, and contact coverage of depression using the Patient Health Questionnaire-9.

Methods

This cross-sectional study included 1059 individuals who applied to primary health care in Ankara before the onset of pandemic restrictions. Contact coverage was evaluated to include mental health care users.

Results

The prevalence of depression was 22.9%. Individuals who were unemployed (OR: 3.832; 95% CI: 2.053-7.151), women (OR: 1.646; 95% CI: 1.158-2.340), those without social support (OR: 1.933; 95% CI: 1.219-3.065), those who did not receive formal education (OR: 2.631; 95 % CI: 1.312-5.275), lower-income group (OR: 1.528; 95% CI: 1.071-2.180), and unmarried or divorced (OR: 2.644; 95% CI: 1.324-5.281) were found to be at risk of developing depression. Based on the linear regression model including patients diagnosed with depression, individuals who were unemployed (standardized β: 0.190), women (standardized β: 0.075), those without social support (standardized β: 0.096), and those who were unmarried or single (standardized β: 0.147) had the highest scale scores. Contact coverage for depression was 31.0%. Contact coverage was more likely in the upper-income group (OR: 2.239, 95% CI: 1.173-4.273).

Conclusion

Although depression is common among primary health care applicants, contact coverage is low. Developing screening programs for depression in primary health care may help improve community mental health. Socioeconomic factors that contribute to the emergence, severity, and contact coverage of depression indicate health inequalities. The development and severity of depression are mostly due to unemployment, which suggests the importance of employment-enhancing policies.

Community delivery of brief therapy for depressed older adults impacted by Hurricane Sandy

Older adults frequently under-report depressive symptoms and often fail to access services after a disaster. To address unmet mental health needs, we developed a service delivery program (SMART-MH) that combines outreach, assessment, and therapy and implemented it in New York City after Hurricane Sandy. This study aimed to examine the feasibility, effectiveness, and patients' engagement of our brief psychotherapy ("Engage"). We predicted that Engage would result in reductions of depression, and that the benefits would be comparable to those of a historical comparison group who received Engage in a controlled experimental setting. A total of 2,831 adults (age ≥ 60) impacted by Hurricane Sandy were screened for depression. Assessments and therapy were conducted in English, Spanish, Cantonese, and Russian. Depressed individuals (PHQ-9 ≥ 10) who were not in treatment were offered Engage therapy in their native language at local senior center/nutrition sites. Twelve percent of the participants reported depression (N = 333). Of these 333 participants, 201 (60%) were not receiving treatment and 143 agreed to receive Engage therapy. Linear mixed-effects model showed that depression severity decreased significantly over time. More than two thirds had a five-point reduction in PHQ-9 scores and post-treatment scores ≤9. Post-hoc comparison of standardized slopes of change found patterns of depression reductions equivalent to Engage provided in a controlled setting. Partnerships to integrate mental health care into community settings can increase detection of mental-health needs and access to services in patients' native language. Brief reward exposure-based psychotherapy delivered in the community can provide comparable benefits to those achieved in research settings.

The Relationship Between Maladaptive Personality and Social Role Impairment in Depressed Older Adults in Primary Care

Objective: Personality pathology is associated with impaired social functioning in adults, though further evidence is needed to examine the individual contributions of personality traits and processes to social functioning in depressed older adults. This study is a secondary analysis examining the relationship between maladaptive personality traits and processes and social role impairment in depressed older adults in primary care. Methods: Participants (N = 56) were 77% female and ranged in age between 55-89 (M = 66.82, SD = 8.75). Personality pathology was measured by maladaptive traits (NEO-FFI) and processes (Inventory of Interpersonal Problems; IIP-PD-15). Individual variable as well as combined predictive models of social role impairment were examined. Results: Higher neuroticism (β = 0.30, p < .05), lower agreeableness (β = -0.35 p < .001) and higher IIP-PD-15 (β = 0.28, p < .01) scores predicted greater impairment in social role functioning. A combined predictive model of neuroticism and IIP-PD-15 scores predicted unique variance in social role impairment (R² = .71). Conclusion: These results link select personality traits and interpersonal processes to social role impairment, suggesting that these are indicators of personality pathology in older adults. Clinical Implications: These findings lend preliminary support for clinical screening of personality pathology in depressed older adults utilizing both personality trait and process measures.

Treatment Adequacy and Adherence as Predictors of Depression Response in Primary Care

OBJECTIVE

Primary care is the de facto mental health system in the United States where physicians treat large numbers of depressed older adults with antidepressant medication. This study aimed to examine whether antidepressant dosage adequacy and patient adherence are associated with depression response among middle-aged and older adults prescribed with antidepressants by their primary care provider.

DESIGN

A secondary analysis was conducted on a sample drawn from a randomized controlled trial comparing Treatment as Usual to Treatment Initiation Program, an adherence intervention. Treatment Initiation Program improved adherence but not depression compared to Treatment as Usual (Sirey et al., 2017). For this analysis, we examined dosing adequacy and adherence at 6 and 12 weeks as predictors of depression response in both groups at 12 and 24 weeks.

SETTING

Primary care practices.

PARTICIPANTS

One hundred eighty-seven older adults with depression prescribed an antidepressant for depression by their primary care provider.

MEASUREMENTS

Depression response was defined as 50% reduction on the Hamilton Rating Scale for Depression. Adherence was defined as taking 80% of doses at follow-up interviews (6 and 12 weeks). Patient-reported dosage and duration of antidepressant therapy was collected using the Composite Antidepressant Score (adequacy score of >3) at follow-up.

RESULTS

Greater adherence, but not receipt of adequate dosage, was associated with higher likelihood of treatment response at both 12 (Odds ratio (OR) = 2.63; 95% Confidence Interval (CI), 1.19-5.84) and 24 weeks (OR = 3.09; 95% CI, 1.46-6.55).

CONCLUSION

As physicians prescribe antidepressants to the diverse group of adults seen in primary care, special attention to patients' views and approach to adherence may improve depression outcomes.

Spontaneous Participation in Secondary Prevention Programs: The Role of Psychosocial Predictors

Disease prevention is a multifaceted construct that has been widely studied. Nevertheless, in spite of its importance, it is still not sufficiently considered by the general population. Since the reasons for this lack of consideration are not yet fully understood, we created an Online Prevention Survey (OPS) to investigate the role of both sociodemographic and psychological factors in predicting individuals’ spontaneous participation in secondary prevention programs. The results revealed that younger people, men, manual workers, unemployed people, and those who do not regularly practise physical activity were less likely to spontaneously participate in such programs. Furthermore, an analysis of the psychological determinants of the willingness to participate in secondary prevention programs showed that depressive symptoms negatively predict it, while an individual’s perception of receiving high social support acts as a positive predictor. Based on these results, we suggest the need for implementing new tailored approaches to promote prevention initiatives to those segments of the population which are more reluctant to spontaneously undertake prevention paths.

Depression in Rural Communities and Primary Care Clinics in Chiapas, Mexico

Depression is a leading cause of disability worldwide and can be diagnosed and treated in primary care clinics. No studies to date have demonstrated the prevalence of depression in rural, primary care settings in Mexico. The objective of this study is to describe the prevalence of visits for depression in primary care settings in one group of rural communities within Chiapas, Mexico. We performed a cross-sectional, retrospective study of depression prevalence in primary care clinics in the Sierra region of Chiapas, Mexico during the calendar year of 2014. We determined the average depression prevalence is 7.9% (6 community clinics, n = 4555). The prevalence of depression in rural Chiapas, Mexico is much higher than the Mexican national average of 4.0–4.5% found in a home-based survey. Further efforts to understand the causes, develop improved mental health services in primary care, and reduce the higher burden of depression in rural communities in Mexico are urgently needed.

Patient and public involvement in integrated psychosocial care

Purpose

Recent models of care incorporate service user involvement within the development and sustainability of a quality improvement project. The purpose of this paper is to demonstrate the significance of working with patients and members of the public for the integration of psychosocial care into long-term condition (LTC) management.

Design/methodology/approach

Research shows that mental health difficulties are more prevalent in people with LTC. The three Dimensions for Long-term Conditions (3DLC) is a patient-centred multidisciplinary service which integrates psychological and social care into the usual physical care. Thematic analysis was conducted on the discussions of the two patient and public involvement workshops that were facilitated by the service. The workshops included healthcare professionals, patients with LTC and their carers.

Findings

Several themes and subthemes emerged which highlighted the importance of discussing and treating mental health in a physical health setting, the challenges that both the patients and healthcare professionals encounter and the ways in which an integrated care service may address these barriers. The findings show that there was an emphasis on patient-centeredness, accessibility of services and the need for better communication.

Practical implications

People with LTC can be empowered to better self-manage their condition, whilst having access to all types of care, physical, social and psychological. By involving service users in the implementation process of the 3DLC service, the components of an effective integrated service are delineated.

Originality/value

The service users have identified barriers and facilitators of integrating a biopsychosocial model in care pathways. This has helped the 3DLC team to further develop the model to ensure improvements in condition-specific outcomes, quality of life and healthcare utilisation.

Assessing rates and contextual predictors of 5-year mortality among HIV-infected and HIV-uninfected individuals following HIV testing in Durban, South Africa

Background

Little is known about contextual factors that predict long-term mortality following HIV testing in resource-limited settings. We evaluated the impact of contextual factors on 5-year mortality among HIV-infected and HIV-uninfected individuals in Durban, South Africa.

Methods

We used data from the Sizanani trial (NCT01188941) in which adults (≥18y) were enrolled prior to HIV testing at 4 outpatient sites. We ascertained vital status via the South African National Population Register. We used random survival forests to identify the most influential predictors of time to death and incorporated these into a Cox model that included age, gender, HIV status, CD4 count, healthcare usage, health facility type, mental health, and self-identified barriers to care (i.e., service delivery, financial, logistical, structural and perceived health).

Results

Among 4816 participants, 39% were HIV-infected. Median age was 31y and 49% were female. 380 of 2508 with survival information (15%) died during median follow-up of 5.8y. For both HIV-infected and HIV-uninfected participants, each additional barrier domain increased the HR of dying by 11% (HR 1.11, 95% CI 1.05–1.18). Every 10-point increase in mental health score decreased the HR by 7% (HR 0.93, 95% CI 0.89–0.97). The hazard ratio (HR) for death of HIV-infected versus HIV-uninfected varied by age: HR of 6.59 (95% CI: 4.79–9.06) at age 20 dropping to a HR of 1.13 (95% CI: 0.86–1.48) at age 60.

Conclusions

Independent of serostatus, more self-identified barrier domains and poorer mental health increased mortality risk. Additionally, the impact of HIV on mortality was most pronounced in younger persons. These factors may be used to identify high-risk individuals requiring intensive follow up, regardless of serostatus.

The association of late-life depression with all-cause and cardiovascular mortality among community-dwelling older adults: systematic review and meta-analysis

BACKGROUND

Late-life depression has become an important public health problem. Available evidence suggests that late-life depression is associated with all-cause and cardiovascular mortality among older adults living in the community, although the associations have not been comprehensively reviewed and quantified.AimTo estimate the pooled association of late-life depression with all-cause and cardiovascular mortality among community-dwelling older adults.

METHOD

We conducted a systematic review and meta-analysis of prospective cohort studies that examine the associations of late-life depression with all-cause and cardiovascular mortality in community settings.

RESULTS

A total of 61 prospective cohort studies from 53 cohorts with 198 589 participants were included in the systematic review and meta-analysis. A total of 49 cohorts reported all-cause mortality and 15 cohorts reported cardiovascular mortality. Late-life depression was associated with increased risk of all-cause (risk ratio 1.34; 95% CI 1.27, 1.42) and cardiovascular mortality (risk ratio 1.31; 95% CI 1.20, 1.43). There was heterogeneity in results across studies and the magnitude of associations differed by age, gender, study location, follow-up duration and methods used to assess depression. The associations existed in different subgroups by age, gender, regions of studies, follow-up periods and assessment methods of late-life depression.

CONCLUSION

Late-life depression is associated with higher risk of both all-cause and cardiovascular mortality among community-dwelling elderly people. Future studies need to test the effectiveness of preventing depression among older adults as a way of reducing mortality in this population. Optimal treatment of late-life depression and its impact on mortality require further investigation.Declaration of interestNone.

Differences in Speed of Response of Depressive Symptom Dimensions in Older Persons During Electroconvulsive Therapy

INTRODUCTION

Electroconvulsive therapy (ECT) is an important and effective treatment for depression. However, research on course trajectories of depressive symptoms during ECT is limited. Insight into putative differences in speed of response of depressive symptom dimensions may enable clinicians to optimally inform patients and their relatives. Therefore, we aim to examine course trajectories of depressive symptom dimensions in depressed older persons during ECT.

METHODS

Data were derived from the Mood Disorders in Elderly treated with Electro Convulsive Therapy study, including 110 persons, aged 55 years or more, with a current diagnosis of major depressive disorder and referred for ECT. Exploratory factor analysis was used to identify symptom dimensions, using the 10 depression items of the Montgomery-Åsberg Depression Rating Scale (MADRS). Differences in course trajectories of symptom dimension during 2 weeks were examined by multilevel analyses.

RESULTS

Three symptom dimensions were identified: a "mood," "melancholic," and "suicidal" dimension. Mood showed a significantly greater severity decline as compared with melancholic and suicidal at the 1-week follow-up. At the 2-week follow-up, both mood and melancholic demonstrated a significantly greater decline as compared with suicidal. However, because scores on the suicidality item of the Montgomery-Asberg Depression Rating Scale were already lower at baseline compared with the other items, a floor effect cannot be ruled out.

DISCUSSION

All symptom dimensions of depression showed a rapid response to ECT. Our findings did not support the general assumption that suicidal symptoms may be the first to improve. However, a floor effect on the suicidality item cannot be ruled out.

Models of care for populations with chronic conditions and mental/behavioral health comorbidity

Recent decades have seen increased interest in the integration of mental and physical healthcare. Healthcare reform in the US has provided an opportunity for integration of evidence-based mental health programmes. Three quarters of patients with behavioural health disorders are seen in medical settings, where behavioural problems are largely unaddressed. The human and economic toll of unaddressed mental and behavioural health needs is enormous and often hidden from view, since the behavioural or mental health implications of medical conditions like heart disease and diabetes have only recently begun to be appreciated. This paper has three goals: (1) to review models of integrated services delivery, providing a framework for making sense of strategies for integration; (2) to consider some evidence for clinical outcomes when care is integrated; and (3) to highlight some factors that enhance or impede integration in practice. The review concludes with comments on where the field is going.

Integrated Care for Depression in Older Primary Care Patients

For decades, depression in older adults was overlooked and not treated. Most treatment was by primary care providers and typically poorly managed. Recent interventions that integrate mental health services into primary care have increased the number of patients who are treated for depression and the quality of that treatment. The most effective models involve systematic depression screening and monitoring, multidisciplinary teams that include primary care providers and mental health specialists, a depression care manager to work directly with patients over time and the use of guideline-based depression treatment. The article reviews the challenges and opportunities for providing high-quality depression treatment in primary care; describes the 3 major integrated care interventions, PRISM-E, IMPACT, and PROSPECT; reviews the evidence of their effectiveness, and adaptations of the model for other conditions and settings; and explores strategies to increase their scalability into real world practice.

Using postal questionnaires to identify carer depression prior to initial patient contact

Aims and Method

To assess whether postal questionnaires, used as a local initiative, were useful in identifying carer depression allowing early support for community-dwelling carers of older adults with mental health needs. the Geriatric Depression Scale and a questionnaire collecting information on the carer's circumstances were sent to carers of consecutive patients routinely referred to a community mental health team for older adults in south London. Rates of carer depression between postal questionnaire responders and non-responders were compared.

Results

The response rate to the postal questionnaires (33%) was similar to that observed in other postal studies; 42% of responders had depression compared with only 4.6% of non-responders.

Clinical Implications

Pre-contact postal questionnaires may present a simple method of enhancing early detection of carer depression for minimal economic outlay.

Cancer, the mind and the person: what we know about the causes of cancer

At a time when patients are challenged to cope adaptively with both the diagnosis and treatment of cancer, clinicians need to respond appropriately to the many inevitable questions about the causes of cancer and contributing factors, including ‘Is this my fault?’. The evidence guiding answers to such questions has been confounded by many methodological challenges, but personality, stress and life events are no longer considered causes of cancer. However, social isolation, untreated depression and social deprivation continue to influence quality of life and reduce cancer survival times. Psychiatry might play a role in promoting lifestyle changes that reduce the risk of cancer, but more importantly it can influence disease progression by optimising patients' adaptation to the many challenges that cancer brings.

Depressive subtypes in an elderly cohort identified using latent class analysis

BACKGROUND

Clinical findings indicate heterogeneity of depressive disorders, stressing the importance of subtyping depression for research and clinical care. Subtypes of the common late life depression are however seldom studied. Data-driven methods may help provide a more empirically-based classification of late-life depression.

METHODS

Data were used from the Netherlands Study of Depression in Older People (NESDO) derived from 359 persons, aged 60 years or older, with a current diagnosis of major depressive disorder. Latent class analysis (LCA) was used to identify subtypes of depression, using ten CIDI-based depression items. Classes were then characterized using various sociodemographic and clinical characteristics.

RESULTS

The most prevalent class, as identified by LCA, was a moderate-severe class (prevalence 46.5%), followed by a severe melancholic class (prevalence 38.4%), and a severe atypical class (prevalence 15.0%). The strongest distinguishing features between the three classes were appetite and weight and, to a lesser extent, psychomotor symptoms and loss of interest. Compared with the melancholic class, the severe atypical class had the highest prevalence of females, the lowest mean age, the highest BMI, and highest prevalence of both cardiovascular disease, and metabolic syndrome.

LIMITATIONS

The strongest distinguishing symptoms, appetite and weight, could be correlated. Further, only longitudinal studies could demonstrate whether the identified classes are stable on the long term.

DISCUSSION

In older persons with depressive disorders, three distinct subtypes were identified, similar to subtypes found in younger adults. The strongest distinguishing features were appetite and weight; moreover, classes differed strongly on prevalence of metabolic syndrome and cardiovascular disease. These findings suggest differences in the involvement of metabolic pathways across classes, which should be considered when investigating the pathogenesis and (eventually) treatment of depression in older persons.

Association of androgen deprivation therapy and depression in the treatment of prostate cancer: A systematic review and meta-analysis

BACKGROUND

There is increasing evidence that androgen deprivation therapy (ADT) may be associated with depression. Existing studies have shown conflicting results.

METHODS

PubMed, Web of Science, Embase, and PsycINFO were queried on April 5, 2017. Eligible studies were in English and reported depression among individuals with prostate cancer exposed to a course of ADT vs. a lesser-exposed group (e.g., any-ADT vs. no ADT and continuous ADT vs. intermittent ADT). We used the MOOSE statement guidelines and the Cochrane Review Group's data extraction template. Study quality was evaluated by Newcastle-Ottawa Scale criteria. We conducted a random-effects meta-analysis to calculate summary statistic risk ratios (RRs) and 95% CIs. Heterogeneity was quantified using the I² statistic and prespecified subgroup analysis. Small study effects were evaluated using Begg and Egger statistics.

RESULTS

A total of 1,128 studies were initially identified and evaluated. A meta-analysis of 18 studies among 168,756 individuals found that ADT use conferred a 41% increased risk of depression (RR = 1.41; 95% CI: 1.18-1.70; P<0.001). We found a consistent strong statistically significant association when limiting our analysis to studies in localized disease (RR = 1.85; 95% CI: 1.20-2.85; P = 0.005) and those using a clinical diagnosis of depression (RR = 1.19; 95% CI: 1.08-1.32; P = 0.001). We did not find an association for continuous ADT with depression risk compared to intermittent ADT (RR = 1.00; 95% CI: 0.50-1.99; P = 0.992). There was no statistically significant evidence of small study effects. Statistically significant heterogeneity in the full analysis (I² = 80%; 95% CI: 69-87; P<0.001) resolved when examining studies using a clinical diagnosis of depression (I² = 16%; 95% CI: 0-60; P = 0.310).

CONCLUSION

The currently available evidence suggests that ADT in the treatment of prostate cancer is associated with an increased risk of depression.

Integrating Depression Care Management into Medicare Home Health Reduces Risk of 30- and 60-Day Hospitalization: The Depression Care for Patients at Home Cluster-Randomized Trial

OBJECTIVES

To determine whether a depression care management intervention in Medicare home health recipients decreases risk of hospitalization.

DESIGN

Cluster-randomized trial. Nurse teams were randomized to intervention (12 teams) or enhanced usual care (EUC; 9 teams).

SETTING

Six home health agencies from distinct geographic regions. Home health recipients were interviewed at home and over the telephone.

PARTICIPANTS

Individuals aged 65 and older who screened positive for depression on nurse assessments (N = 755) and a subset who consented to interviews (n = 306).

INTERVENTION

The Depression CARE for PATients at Home (CAREPATH) guides nurses in managing depression during routine home visits. Clinical functions include weekly symptom assessment, medication management, care coordination, patient education, and goal setting. Researchers conducted telephone conferences with team supervisors every 2 weeks.

MEASUREMENTS

Hospitalization while receiving home health services was assessed using data from the home health record. Hospitalization within 30 days of starting home health, regardless of how long recipients received home health services, was assessed using data from the home care record and research assessments.

RESULTS

The relative hazard of being admitted to the hospital directly from home health was 35% lower within 30 days of starting home health care (hazard ratio (HR) = 0.65, P = .01) and 28% lower within 60 days (HR = 0.72, P = .03) for CAREPATH participants than for participants receiving EUC. In participants referred to home health directly from the hospital, the relative hazard of being rehospitalized was approximately 55% lower (HR = 0.45, P = .001) for CAREPATH participants.

CONCLUSION

Integrating CAREPATH depression care management into routine nursing practice reduces hospitalization and rehospitalization risk in older adults receiving Medicare home health nursing services.

Antidepressant Medication Treatment and Risk of Death

OBJECTIVE

Although previous studies have assessed whether depression is a mortality risk factor, few have examined whether antidepressant medications (ADMs) influence mortality risk.

METHODS

We estimated hazards of 1-year all-cause mortality associated with ADMs, with use occurring within 90 days of depression diagnosis among 720 821 patients who received treatment in a Veterans Health Administration facility during fiscal year 2006. We addressed treatment selection biases using conventional Cox regression, propensity-stratified Cox regression (propensity score), and 2 forms of marginal structural models. Models accounted for multiple potential clinical and demographic confounders, and sensitivity analyses compared findings by antidepressant class.

RESULTS

Antidepressant medication use compared with no use was associated with significantly lower hazards of 1-year mortality risk in Cox (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.90-0.97) and propensity score estimates (HR, 0.94; 95% CI, 0.91-0.98), whereas marginal structural model-based estimates showed no difference in mortality risk when the exposure was specified as "as-treated" in every 90-day intervals of the 1-year follow-up (HR, 0.91; 95% CI, 0.66-1.26) but showed increased risk when specified as "intent-to-treat" (HR, 1.07; 95% CI, 1.02-1.13).

CONCLUSIONS

Among patients treated with ADMs belonging to a single class in the first 90 days, there were no significant differences in 1-year all-cause mortality risks. When accounting for clinical and demographic characteristics and treatment selection bias, ADM use was associated with no excess harm.

Evaluation of clinical pharmacy services within the primary care-mental health integration model at the Tuscaloosa Veterans Affairs Medical Center

Introduction

The purpose of this review is to evaluate the direct delivery of health care to veterans before and after incorporating clinical pharmacy services within primary care mental health integration (PCMHI) at the Tuscaloosa Veterans Affairs Medical Center. Prior to establishing the role of the clinical pharmacy specialist (CPS) within PCMHI, the primary care providers deferred all mental health assessments to specialty mental health. As the demands of the service grew exponentially, assistance from clinical pharmacy was critical.

Methods

A randomized, computer-generated list of 114 patients selected for the retrospective chart review was used to evaluate clinical outcomes in patients enrolled in the PCMHI clinic 1 year preincorporation and postincorporation of CPS. Outcome measures included the number of patients discharged from the PCMHI clinic upon achieving therapeutic goals or discharged to specialty mental health due to therapeutic failure or adverse drug events with first- and second-line psychotropic agents.

Results

When contrasting the end points, there was a 60% increase in the number of patients who achieved therapeutic goal and a 32% decrease in the number of patients discharged to specialty mental health clinic postincorporation of CPS into PCMHI as compared to preincorporation of CPS (P = .024).

Discussion

The results support the significance of CPS in the PCMHI in providing pharmacotherapy, patient education, and medication monitoring for managing psychiatric conditions, such as depression, anxiety, and insomnia. In addition, patients had greater accessibility to medication and frequent monitoring and follow-up, ultimately improving patient outcomes.

[Depression, anxiety, stress, and mortality]

The analytical paper summarizes the main results of recent investigations of the relationships of depression, anxiety, and stress with overall and cardiovascular mortality. It shows that depression and stress are associated with an increased risk of death mainly from cardiovascular diseases, and depression treatment and stress control can increase life expectancy.

Adherence to antidepressant therapy and mortality rates in ischaemic heart disease: cohort study

BACKGROUND

The use of antidepressant drugs in patients with ischaemic heart disease (IHD) has been debated owing to scarcity of data and conflicting results regarding the effect of these drugs on mortality.

AIMS

To evaluate the association between adherence to antidepressant therapy and all-cause mortality in a population-based cohort of patients with IHD.

METHOD

A total of 63 437 patients with IHD who purchased antidepressants at least once during the years 2008-2011 were retrospectively followed for all-cause mortality over 4 years. Adherence was measured as a ratio between claimed and prescribed durations of medication and modelled as non-adherence (<20%), poor (20-50%), moderate (50-80%) and good (>80%). We used multivariable survival analyses adjusted for demographic and clinical variables that may affect mortality.

RESULTS

The moderate and good adherence groups had significantly reduced adjusted mortality hazard ratios of 0.83 (95% CI 0.78-0.88) and 0.86 (95% CI 0.82-0.90) respectively, compared with the non-adherence group.

CONCLUSIONS

Adherence to antidepressant pharmacotherapy is associated with reduced all-cause mortality in a population-based large sample cohort of patients with IHD. Physicians and health policy decision-makers should step up their efforts to sustain and enhance these patients' adherence to their antidepressant regimen.

Interaction of depressive and anxiety symptoms on the mortality of patients with COPD: a preliminary study

BACKGROUND

Depressive and anxiety symptoms increase the risk of death in patients with Chronic Obstructive Pulmonary Disease (COPD), but the combined effects of the two factors are unknown.

PURPOSE

To assess the possible interactive effects of depressive and anxiety symptoms on the death of patients with COPD.

METHODS

Prospective data for 7787 Chinese patients with COPD was analyzed and the deaths were recorded. Depressive and anxiety symptoms were evaluated using the Hospital Anxiety and Depression Scale. A product of depressive and anxiety symptoms was added to the logistic regression model to evaluate the multiplicative interaction, and relative excess risk of interaction (RERI), attributable proportion (AP) of interaction, and synergy index (S) were applied to evaluate the additive interaction of the two factors. Bootstrap was used to calculate 95% confidence intervals (CIs) of RERI, AP and S. RERI > 0, AP > 0, or S > 1 indicated biological interaction.

RESULTS

After 4 years' follow-up, the cumulative mortality was 20.0%, and the percentages of deaths in patients with depressive and anxiety symptoms were 28.5% and 30.9%, respectively. When adjusting for variables such as age, sex, disease duration, marital status, income, education level, co-morbidity, smoke status, biomass smoke, 6MWD, MRC, BMI and FEV1. the RERI, AP, and S (with 95% CIs) resulted in depression and anxiety scores of 6.54 (1.23-13.79), 0.54 (0.18-0.83), and 2.64 (1.33-4.75) respectively.

CONCLUSION

Interaction effects were found between depressive and anxiety symptoms on the death of patients with COPD. Patients with both depressive and anxiety symptoms have an increased risk of death from COPD.

Weighing projections of physical decline in lung cancer surgery decisions

BACKGROUND

Patients with early-stage lung cancer often have comorbid illnesses and fear debility and death when contemplating surgery. However, data that compare physical function of patients who receive surgery with similar patients who do not are sparse. The authors report 1-year outcome results for surgical and nonsurgical patients in a prospective lung cancer cohort to address this gap.

METHODS

The authors enrolled 386 patients with early-stage lung cancer. A 106-item survey was completed at the time of enrollment including the Short-Form 12 (SF-12) Health Survey to assess functional status. Patients were followed for a year. Chart abstractions were obtained to determine comorbid illnesses and surgical status. Death was ascertained through vital records. The SF-12 was repeated 1 year after the enrollment. Regression models were constructed to identify predictors of 1-year mortality and decline in physical function.

RESULTS

Fifty-nine patients (15.3%) died before 1-year follow-up. Mortality in the surgical group was 10.8% compared with 22.8% in the nonsurgical group (P < 0.001). In regression analysis controlling for age and comorbidities, surgical treatment was associated with a reduction in 1-year mortality (odds ratio: 0.5 and 95% confidence interval: 0.3-1.0) but did not worsen physical function relative to the untreated group (average decrease in physical component score of SF-12 = 1.9 for surgery group and 2.5 for no surgery group, P = 0.66).

CONCLUSIONS

Functional decline between surgically treated and untreated patients did not differ. This result casts doubt on its value as a treatment determinant. Cancer mortality seems to be a more essential issue in treatment decisions.

Current understanding of the neurobiology and longitudinal course of geriatric depression

Late life depression is a complex disease associated with a number of contributing neurobiological factors, including cerebrovascular disease, neurodegeneration, and inflammation, which also contribute to its longitudinal prognosis and course. These factors create a context in which the brain is more vulnerable to the impact of stress, and thus, to depression. At the same time, some individuals are protected from late life depression and its consequences, even in the face of neurobiological vulnerability, through benefitting from one or more attributes associated with resilience, including social support, engagement in physical and cognitive activities, and brain reserve. Enhanced understanding of how neurobiological and environmental factors interact in predicting vulnerability and resilience is needed to predict onset and course of depression in late life and develop more effective interventions.

Thoughts of self-harm and depression as prognostic factors in palliative care patients

BACKGROUND

This study explored whether scores indicating depression on Patient Health Questionnaire 9 and patient reports of thoughts of self-harm were prognostic factors for survival in advanced cancer.

METHOD

Patients with advanced cancer were recruited into the study from palliative care day units and invited to complete measures for depression which included Patient Health Questionnaire 9, and Edinburgh Depression Scale at recruitment, and at 8, 16 and 24 weeks.

RESULTS

629 patients were recruited into the study; 139 (22%) died during 6 months follow up and 235 patients (37.4%) died during the study period. The age range of patients recruited was 21-94 years-mean age 66 years and 67% of patients recruited were female. The overall median survival of patients recruited was 37.1 weeks (95% CI 36.0, 39.9 weeks) (range 0-116 weeks). The estimated median survival time of patients whose baseline PHQ9≥9 was 36 weeks with 95% confidence interval of (31, 39) and for patients whose baseline PHQ9<9 was 39 weeks (95% CI 37, 45)-baseline PHQ9 alone was predictive of death. The median survival times were 37.9 weeks for patients who did not indicate thoughts of self-harm and 34.7 weeks for patients who reported thoughts of self-harm at baseline suggesting that risk of death was 1.4 times higher among patients who reported thoughts of self-harm.

LIMITATIONS

Patients were recruited only from within palliative day care units and assessments were made only by validated tools and not by clinical interviews.

CONCLUSIONS

In this large longitudinal study, moderate to severe depression as measured by PHQ9 and patient reports of thoughts of self-harm were associated with earlier mortality. This paper supports the need for supporting patients psychologically at the end of life and specifically in treating depression in this patient group.

Choosing treatment for depression in older adults and evaluating response

An update is provided on the current information regarding late life depression with regard to assessment, clinical implications, and treatment recommendations. Several treatments are considered evidence-based, but when deployed into field trials, the efficacy of these treatments falls short. It is thought that the lower impact in community trials is due in large part to patient, clinical, environmental, socio-economic, and cognitive correlates that influence treatment response. The aim is to assist providers in making decisions about what type of treatment to recommend based on a sound assessment of these clinical correlates.

The interface of physical and mental health

PURPOSE

The interaction between physical and mental health is complex. In this paper we aim to provide an overview of the main components of this relationship and to identify how care could be improved for people with co-morbidities.

METHODS

We performed a literature search of MedLine, Ovid and Psycinfo and identified studies that examined the association between mental illness and physical illness. We also examined the key policy documents and guidelines in this area.

RESULTS

People with mental health conditions are at higher risk of developing physical illness, have those conditions diagnosed later and have much higher mortality rates. Conversely, people with a diagnosis of physical illness, especially cardiovascular disease, diabetes and cancer have a greater chance of developing a mental health problem. When both mental and physical illnesses conditions are present together, there are higher overall rates of morbidity, healthcare utilisation, and poorer quality of life.

CONCLUSIONS

Physicians and psychiatrists need to be aware of the co-occurrence of mental and physical health problems and the challenges posed for both general and mental health services. There is a need to screen appropriately in both settings to ensure timely diagnosis and treatment. Liaison psychiatry provides psychological assessment and treatment for people with physical illness, but there is a gap in the provision of physical healthcare for people with severe mental illness. There is a need for public policy to drive this forward to overcome the institutional barriers to equitable access to healthcare and for educators to reverse the tendency to teach mind and body as separate systems.

Effect of collaborative care for depression on risk of cardiovascular events: data from the IMPACT randomized controlled trial

OBJECTIVE

Although depression is a risk and prognostic factor for cardiovascular disease (CVD), depression trials involving cardiac patients have not observed the anticipated cardiovascular benefits. To test our hypothesis that depression treatment delivered before clinical CVD onset reduces risk of CVD events, we conducted an 8-year follow-up study of the Indiana sites of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) randomized controlled trial.

METHODS

Participants were 235 primary care patients 60 years or older with major depression or dysthymia who were randomized to a 12-month collaborative care program involving antidepressants and psychotherapy (85 without and 35 with baseline CVD) or usual care (83 without and 32 with baseline CVD). Hard CVD events (fatal/nonfatal) were identified using electronic medical record and Medicare/Medicaid data.

RESULTS

A total of 119 patients (51%) had a hard CVD event. As hypothesized, the treatment × baseline CVD interaction was significant (p = .021). IMPACT patients without baseline CVD had a 48% lower risk of an event than did usual care patients (28% versus 47%, hazard ratio = 0.52, 95% confidence interval = 0.31-0.86). The number needed to treat to prevent one event for 5 years was 6.1. The likelihood of an event did not differ between IMPACT and usual care patients with baseline CVD (86% versus 81%, hazard ratio = 1.19, 95% confidence interval, 0.70-2.03).

CONCLUSIONS

Collaborative depression care delivered before CVD onset halved the excess risk of hard CVD events among older, depressed patients. Our findings raise the possibility that the IMPACT intervention could be used as a CVD primary prevention strategy.

The economic, public health, and caregiver burden of late-life depression

This article reviews the burden of late-life depression (LLD) from several perspectives, including costs of depression treatment and treatment of other comorbid psychiatric and medical conditions; the impact of LLD on job functioning, disability, and retirement; and how LLD influences others, such as family members and caregivers.

Racial differences in adherence to antidepressant treatment in later life

OBJECTIVE

Although antidepressants are an effective treatment for later-life depression, older patients often choose not to initiate or to discontinue medication treatment prematurely. Although racial differences in depression treatment preferences have been reported, little is known about racial differences in antidepressant medication adherence among older patients.

DESIGN

Prospective, observational study comparing antidepressant adherence for older African American and white primary care patients.

PARTICIPANTS

A total of 188 subjects age 60 and older, diagnosed with clinically significant depression with a new recommendation for antidepressant treatment by their primary care physician.

MEASUREMENT

Study participants were assessed at study entry and at the 4-month follow-up (encompassing the acute treatment phase). Depression medication adherence was based on a well-validated self-report measure.

RESULTS

At the 4-month follow-up, 61.2% of subjects reported that they were adherent to their antidepressant medication. In unadjusted and two of the three adjusted analyses, African American subjects (n = 82) had significantly lower rates of 4-month antidepressant adherence than white subjects (n = 106). African American women had the lowest adherence rates (44.4%) followed by African American men (56.8%), white men (65.3%), and white women (73.7%). In logistic regression models controlling for demographic, illness, and functional status variables, significant differences persisted between African American women and white women in reported 4-month antidepressant adherence (OR: 3.58, 95% CI: 1.27-10.07, Wald χ(2) = 2.42, df = 1, p <0.02).

CONCLUSIONS

The results demonstrate racial and gender differences in antidepressant adherence in older adults. Depression treatment interventions for older adults should take into account the potential impact of race and gender on adherence to prescribed medications.

Treatment receipt and outcomes among lung cancer patients with depression

AIMS

Among lung cancer patients, depression has been associated with increased mortality, although the mechanisms are unknown. We evaluated the association of depression with mortality and receipt of cancer therapies among depressed veterans with lung cancer.

MATERIALS AND METHODS

A retrospective, cohort study of lung cancer patients in the Veterans Affairs-Northwest Health Network from 1995 to 2010. Depression was defined by ICD-9 coding within 24 months before lung cancer diagnosis. Multivariable Cox proportional analysis and logistic regression were used.

RESULTS

In total, 3869 lung cancer patients were evaluated; 14% had a diagnosis of depression. A diagnosis of depression was associated with increased mortality among all stage lung cancer patients (hazard ratio = 1.14, 95% confidence interval: 1.03-1.27, P = 0.01). Among early-stage (I and II) non-small cell lung cancer (NSCLC) patients, the hazard ratio was 1.37 (95% confidence interval: 1.12-1.68, P = 0.003). There was no association of depression diagnosis with surgery (odds ratio = 0.83, 95% confidence interval: 0.56-1.22, P = 0.34) among early-stage NSCLC patients. A depression diagnosis was not associated with mortality (hazard ratio = 1.02, 95% confidence interval: 0.89-1.16, P = 0.78) or chemotherapy (odds ratio = 1.07, 95% confidence interval: 0.83-1.39, P = 0.59) or radiation (odds ratio = 1.04, 95% confidence interval: 0.81-1.34, P = 0.75) receipt among advanced-stage (III and IV) NSCLC patients. Increased utilisation of health services for depression was associated with increased mortality among depressed patients.

CONCLUSIONS

Depression is associated with increased mortality in lung cancer patients and this association is higher among those with increased measures of depression care utilisation. Differences in lung cancer treatment receipt are probably not responsible for the observed mortality differences between depressed and non-depressed patients. Clinicians should recognise the significant effect of depression on lung cancer survival.

Negative affect and sleep disturbance may be associated with response to epidural steroid injections for spine-related pain

OBJECTIVE

To describe whether negative affect and sleep impairment are associated with the clinical effect of epidural steroid injections (ESIs) for low back pain.

DESIGN

Observational study; patients were evaluated before ESI and 1 and 3 months after ESI.

SETTING

Spine center and related treatment sites.

PARTICIPANTS

Participants (N=158) seeking treatment for low back pain with or without radiculopathy.

INTERVENTION

ESI for low back pain with or without radiculopathy.

MAIN OUTCOME MEASURES

We assessed the dependent (global pain severity for back and leg pain, pain behavior, pain interference) and independent variables (depression, sleep disturbance, and covariates of back pain response) with the Patient-Reported Outcome Measurement Information System (PROMIS) and legacy measures. Outcome was assessed cross-sectionally using multiple regression and longitudinally with path analysis.

RESULTS

After 1 month, sleep disturbance was the only predictor for the global ratings of improvement in back pain (R(2)=16.8%) and leg pain (R(2)=11.4%). The proportions of variance explained by sleep disturbance and negative affect for all dependent variables were greater at 3 months than 1 month. Mediation analysis was significant for negative affect for the 3-month outcomes on PROMIS pain behavior (β=.87, P<.01) and pain interference (β=.37, P<.01). There was no evidence of mediation by sleep disturbance for any outcome.

CONCLUSIONS

Negative affect and sleep disturbance are associated with worse outcomes after ESI. Further research is needed to determine if treatment of negative affect and sleep disturbance prior to or concurrently with ESI will improve outcomes.

A home-based intervention to reduce depressive symptoms and improve quality of life in older African Americans: a randomized trial

BACKGROUND

Effective care models for treating older African Americans with depressive symptoms are needed.

OBJECTIVE

To determine whether a home-based intervention alleviates depressive symptoms and improves quality of life in older African Americans.

DESIGN

Parallel, randomized trial stratified by recruitment site. Interviewers assessing outcomes were blinded to treatment assignment. (ClinicalTrials.gov: NCT00511680).

SETTING

A senior center and participants' homes from 2008 to 2010.

PATIENTS

African Americans aged 55 years or older with depressive symptoms.

INTERVENTION

A multicomponent, home-based intervention delivered by social workers or a wait-list control group that received the intervention at 4 months.

MEASUREMENTS

Self-reported depression severity at 4 months (primary outcome) and depression knowledge, quality of life, behavioral activation, anxiety, function, and remission at 4 and 8 months.

RESULTS

Of 208 participants (106 and 102 in the intervention and wait-list groups, respectively), 182 (89 and 93, respectively) completed 4 months and 160 (79 and 81, respectively) completed 8 months. At 4 months, participants in the intervention group showed reduced depression severity (difference in mean change in Patient Health Questionnaire-9 score from baseline, -2.9 [95% CI, -4.6 to -1.2]; difference in mean change in Center for Epidemiologic Studies Depression Scale score from baseline, -3.7 [CI, -5.4 to -2.1]); improved depression knowledge, quality of life, behavioral activation, and anxiety (P < 0.001); and improved function (P = 0.014) compared with wait-list participants. More intervention than wait-list participants entered remission at 4 months (43.8% vs. 26.9%). After treatment, control participants showed benefits similar in magnitude to those of participants in the initial intervention group. Those in the initial intervention group maintained benefits at 8 months.

LIMITATION

The study had a small sample, short duration, and differential withdrawal rate.

CONCLUSION

A home-based intervention delivered by social workers could reduce depressive symptoms and enhance quality of life in most older African Americans.

Research priorities in geriatric palliative care: nonpain symptoms

Research addressing the burden, assessment, and management of nonpain symptoms associated with advanced illness in older adults is limited. While nonpain symptoms such as fatigue, sleep, dyspnea, anxiety, depression, cognitive impairment, nausea, and anorexia-cachexia are commonly noted by patients and clinicians, research quantifying their effects on quality of life, function, and other outcomes are lacking and there is scant evidence regarding management. Most available studies have focused on relatively narrow conditions (e.g., chemotherapy-induced nausea) and there are almost no data relevant to patients with multiple morbidities or multiple concurrent symptoms. Assessment and treatment of nonpain symptoms in older adults with serious illness and multiple comorbidities is compromised by the lack of data relevant to their care. Recommended research priorities address the documented high prevalence of distressing symptoms in older adults with serious illness, the unique needs of this population due to coexistence of multiple chronic conditions along with physiologic changes related to aging, the lack of evidence for effective pharmacologic and nonpharmacologic interventions, and the need for validated measures that are relevant across multiple care settings.

Long term effect of depression care management on mortality in older adults: follow-up of cluster randomized clinical trial in primary care

OBJECTIVE

To investigate whether an intervention to improve treatment of depression in older adults in primary care modified the increased risk of death associated with depression.

DESIGN

Long term follow-up of multi-site practice randomized controlled trial (PROSPECT-Prevention of Suicide in Primary Care Elderly: Collaborative Trial).

SETTING

20 primary care practices in New York City, Philadelphia, and Pittsburgh, USA, randomized to intervention or usual care.

PARTICIPANTS

1226 participants identified between May 1999 and August 2001 through a two stage, age stratified (60-74; ≥ 75 years) depression screening of randomly sampled patients; enrollment included patients who screened positive and a random sample of patients who screened negative.

INTERVENTION

For two years, a depression care manager worked with primary care physicians in intervention practices to provide algorithm based care for depression, offering psychotherapy, increasing antidepressant dose if indicated, and monitoring symptoms, adverse effects of drugs, and adherence to treatment. This paper reports the long term follow-up.

MAIN OUTCOME MEASURE

Mortality risk based on a median follow-up of 98 (range 0.8-116.4) months through 2008.

RESULTS

In baseline clinical interviews, 396 people were classified as having major depression, 203 had clinically significant minor depression, and 627 did not meet criteria for depression. At follow-up, 405 patients had died. Patients with major depression in usual care were more likely to die than were those without depression (hazard ratio 1.90, 95% confidence interval 1.57 to 2.31). In contrast, patients with major depression in intervention practices were at no greater risk than were people without depression (hazard ratio 1.09, 0.83 to 1.44). Patients with major depression in intervention practices, relative to usual care, were 24% less likely to have died (hazard ratio 0.76, 0.57 to 1.00; P=0.05). Preliminary data on cause of death are provided. No significant effect on mortality was found for minor depression.

CONCLUSIONS

Older adults with major depression in practices provided with additional resources to intensively manage depression had a mortality risk lower than that observed in usual care and similar to older adults without depression.

Economic inequalities in the effectiveness of a primary care intervention for depression and suicidal ideation

BACKGROUND

Economic disadvantage is associated with depression and suicide. We sought to determine whether economic disadvantage reduces the effectiveness of depression treatments received in primary care.

METHODS

We conducted differential-effects analyses of the Prevention of Suicide in Primary Care Elderly: Collaborative Trial, a primary-care-based randomized, controlled trial for late-life depression and suicidal ideation conducted between 1999 and 2001, which included 514 patients with major depression or clinically significant minor depression.

RESULTS

The intervention effect, defined as change in depressive symptoms from baseline, was stronger among persons reporting financial strain at baseline (differential effect size = -4.5 Hamilton Depression Rating Scale points across the study period [95% confidence interval = -8.6 to -0.3]). We found similar evidence for effect modification by neighborhood poverty, although the intervention effect weakened after the initial 4 months of the trial for participants residing in poor neighborhoods. There was no evidence of substantial differences in the effectiveness of the intervention on suicidal ideation and depression remission by economic disadvantage.

CONCLUSIONS

Economic conditions moderated the effectiveness of primary-care-based treatment for late-life depression. Financially strained individuals benefited more from the intervention; we speculate this was because of the enhanced treatment management protocol, which led to a greater improvement in the care received by these persons. People living in poor neighborhoods experienced only temporary benefit from the intervention. Thus, multiple aspects of economic disadvantage affect depression treatment outcomes; additional work is needed to understand the underlying mechanisms.

Sleep disturbance, inflammation and depression risk in cancer survivors

Over two-thirds of the 11.4 million cancer survivors in the United States can expect long-term survival, with many others living with cancer as a chronic disease controlled by ongoing therapy. However, behavioral co-morbidities often arise during treatment and persist long-term to complicate survival and reduce quality of life. In this review, the inter-relationships between cancer, depression, and sleep disturbance are described, with a focus on the role of sleep disturbance as a risk factor for depression. Increasing evidence also links alterations in inflammatory biology dynamics to these long-term effects of cancer diagnosis and treatment, and the hypothesis that sleep disturbance drives inflammation, which together contribute to depression, is discussed. Better understanding of the associations between inflammation and behavioral co-morbidities has the potential to refine prediction of risk and development of strategies for the prevention and treatment of sleep disturbance and depression in cancer survivors.

Depressive symptoms, antidepressants and disability and future coronary heart disease and stroke events in older adults: the Three City Study

To investigate the association between baseline depressive symptoms and first fatal and non fatal coronary heart disease (CHD) and stroke in older adults, taking antidepressants and disability into account. In the Three City Study, a community-based prospective multicentric observational study cohort, 7,308 non-institutionalized men and women aged ≥65 years with no reported history of CHD, stroke or dementia, completed the 20-item Center for Epidemiologic Studies depression scale (CESD) questionnaire. First CHD and stroke events during follow-up were adjudicated by an independent expert committee. Hazard ratios (HRs) were estimated by Cox proportional hazard model. After a median follow-up of 5.3 years, 338 subjects had suffered a first non-fatal CHD or stroke event, and 82 had died from a CHD or stroke. After adjustment for study center, baseline socio-demographic characteristics, and conventional risk factors, depressive symptoms (CESD ≥ 16) were associated with fatal events only: fatal CHD plus stroke (HR = 2.50; 95% CI 1.57-3.97), fatal CHD alone (n = 57; HR = 2.21 ; 95%CI 1.27-3.87), and fatal stroke alone (n = 25; HR = 3.27; 95% CI 1.42-7.52). These associations were even stronger in depressed subjects receiving antidepressants (HR = 4.17; 95% CI 1.84-9.46) and in depressed subjects with impaired Instrumental Activities of Daily Living (HR = 8.93; 95% CI 4.60-17.34). By contrast, there was no significant association with non fatal events (HR for non-fatal CHD or stroke = 0.94; 95% CI 0.66-1.33). In non-institutionalized elderly subjects without overt CHD, stroke or dementia, depressive symptoms were selectively and robustly associated with first fatal CHD or stroke events.

Collaborative care for depression and anxiety problems

BACKGROUND

Common mental health problems, such as depression and anxiety, are estimated to affect up to 15% of the UK population at any one time, and health care systems worldwide need to implement interventions to reduce the impact and burden of these conditions. Collaborative care is a complex intervention based on chronic disease management models that may be effective in the management of these common mental health problems.

OBJECTIVES

To assess the effectiveness of collaborative care for patients with depression or anxiety.

SEARCH METHODS

We searched the following databases to February 2012: The Cochrane Collaboration Depression, Anxiety and Neurosis Group (CCDAN) trials registers (CCDANCTR-References and CCDANCTR-Studies) which include relevant randomised controlled trials (RCTs) from MEDLINE (1950 to present), EMBASE (1974 to present), PsycINFO (1967 to present) and the Cochrane Central Register of Controlled Trials (CENTRAL, all years); the World Health Organization (WHO) trials portal (ICTRP); ClinicalTrials.gov; and CINAHL (to November 2010 only). We screened the reference lists of reports of all included studies and published systematic reviews for reports of additional studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of collaborative care for participants of all ages with depression or anxiety.

DATA COLLECTION AND ANALYSIS

Two independent researchers extracted data using a standardised data extraction sheet. Two independent researchers made 'Risk of bias' assessments using criteria from The Cochrane Collaboration. We combined continuous measures of outcome using standardised mean differences (SMDs) with 95% confidence intervals (CIs). We combined dichotomous measures using risk ratios (RRs) with 95% CIs. Sensitivity analyses tested the robustness of the results.

MAIN RESULTS

We included seventy-nine RCTs (including 90 relevant comparisons) involving 24,308 participants in the review. Studies varied in terms of risk of bias.The results of primary analyses demonstrated significantly greater improvement in depression outcomes for adults with depression treated with the collaborative care model in the short-term (SMD -0.34, 95% CI -0.41 to -0.27; RR 1.32, 95% CI 1.22 to 1.43), medium-term (SMD -0.28, 95% CI -0.41 to -0.15; RR 1.31, 95% CI 1.17 to 1.48), and long-term (SMD -0.35, 95% CI -0.46 to -0.24; RR 1.29, 95% CI 1.18 to 1.41). However, these significant benefits were not demonstrated into the very long-term (RR 1.12, 95% CI 0.98 to 1.27).The results also demonstrated significantly greater improvement in anxiety outcomes for adults with anxiety treated with the collaborative care model in the short-term (SMD -0.30, 95% CI -0.44 to -0.17; RR 1.50, 95% CI 1.21 to 1.87), medium-term (SMD -0.33, 95% CI -0.47 to -0.19; RR 1.41, 95% CI 1.18 to 1.69), and long-term (SMD -0.20, 95% CI -0.34 to -0.06; RR 1.26, 95% CI 1.11 to 1.42). No comparisons examined the effects of the intervention on anxiety outcomes in the very long-term.There was evidence of benefit in secondary outcomes including medication use, mental health quality of life, and patient satisfaction, although there was less evidence of benefit in physical quality of life.

AUTHORS' CONCLUSIONS

Collaborative care is associated with significant improvement in depression and anxiety outcomes compared with usual care, and represents a useful addition to clinical pathways for adult patients with depression and anxiety.

Course of depression and mortality among older primary care patients

CONTEXT

: Depression is a treatable illness that disproportionately places older adults at increased risk for mortality.

OBJECTIVE

: We sought to examine whether there are patterns of course of depression severity among older primary care patients that are associated with increased risk for mortality.

DESIGN AND SETTING

: Our study was a secondary analysis of data from a practice-based randomized controlled trial within 20 primary care practices located in greater New York City, Philadelphia, and Pittsburgh.

PARTICIPANTS

: The study sample consisted of 599 adults aged 60 years and older recruited from primary care settings. Participants were identified though a two-stage, age-stratified (60-74 years; older than 75 years) depression screening of randomly sampled patients. Severity of depression was assessed using the 24-item Hamilton Depression Rating Scale (HDRS).

MEASUREMENTS

: Longitudinal analysis via growth curve mixture modeling was carried out to classify patterns of course of depression severity across 12 months. Vital status at 5 years was ascertained via the National Death Index Plus.

RESULTS

: Three patterns of change in course of depression severity over 12 months were identified: 1) persistent depressive symptoms, 2) high but declining depressive symptoms, 3) low and declining depressive symptoms. After a median follow-up of 52.0 months, 114 patients had died. Patients with persistent depressive symptoms were more likely to have died compared with patients with a course of high but declining depressive symptoms (adjusted hazard ratio 2.32, 95% confidence interval [1.15-4.69]).

CONCLUSIONS

: Persistent depressive symptoms signaled increased risk of dying in older primary care patients, even after adjustment for potentially influential characteristics such as age, smoking status, and medical comorbidity.
