Improving depression outcomes in community primary care practice: a randomized trial of the quEST intervention. Quality Enhancement by Strategic Teaming

The prevalence of depression, determinants, and linkage with functional disability amongst postmenopausal women in India: Evidence from the Longitudinal Ageing Study in India

BACKGROUND

The study objective was estimating the prevalence and determinants of depression amongst postmenopausal women in India. Additionally, we used panel mediation analysis to model the extent to which multimorbidity was associated with depression after adjusting for the effects of functional disability in the participants.

METHODS

Data from 28,160 women aged 50 and above from the Longitudinal Aging Study in India (LASI) Wave 1 were analyzed. Depression was assessed using the Composite International Diagnostic Interview-Short Form (CIDI-SF), with multimorbidity and functional disability (ADL and IADL) considered as key predictor variables. Logistic regression and Karlson-Holm-Breen (KHB) mediation analysis were employed.

RESULTS

The weighted prevalence of depression among women aged ≥ 50 years was 21.76% (95% CI: 20.81, 22.73), significantly higher women aged < 50 years (17.60%, 95% CI: 16.33, 18.94). Factors independently associated with increased odds of depression included being unmarried, rural residence, and multimorbidity, while higher educational status was associated with lower odds of depression. The relationship between multimorbidity and depression was partially mediated by ADL and IADL disabilities. Notable regional (state) variations in the magnitude of depression were observed.

CONCLUSIONS

Nearly one in five postmenopausal women in India aged 50 years and older have clinical depression. Community screening for reaching the unreached with primary care mental health strengthening need enhanced policy focus.

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.

GPs' experiences of a collaborative care model for patients with common mental disorders who need sick leave certification: a qualitative study

BACKGROUND

GPs are an important part of collaboration around patients with common mental disorders (CMD) in primary care. The Co-Work-Care model was implemented to further improve collaboration, and emphasised working more closely with patients through active dialogues among care managers, rehabilitation coordinators, and GPs. This enhanced collaborative model also included a person-centred dialogue meeting with patients' employers.

AIM

The aim of this study was to explore GPs' experiences of the Co-Work-Care model, an organisation of collaborative care at the primary care centre (PCC) that includes a person-centred dialogue meeting in the care of patients with CMD who need sick leave certification.

DESIGN & SETTING

Qualitative individual and group interviews were conducted with Swedish GPs with experience of the Co-Work-Care trial where the PCC was an intervention PCC with the enhanced collaboration model.

METHOD

GPs were sampled purposefully from different Co-Work-Care intervention PCCs in Sweden. Focus group and individual, in-depth semi-structured interviews were conducted. All interviews were analysed by systematic text condensation (STC), according to Malterud.

RESULTS

The following three codes describing the GPs' experiences of working in the Co-Work-Care model were identified: (1) a structured work approach; (2) competency of the care manager and the rehabilitation coordinator; and (3) gaining control through close collaboration.

CONCLUSION

Overall, GPs' experience was that the enhanced collaboration reduced their workload and enabled them to focus on medical care. Patient care was perceived as safer and more effective. These advantages may result in higher quality in medical and rehabilitation decisions, as well as a more sustainable and less stressful work situation for GPs.

Nurse-led task-shifting strategies to substitute for mental health specialists in primary care: A systematic review

AIM

The study aimed to synthesize evidence comparing task-shifting interventions led by general practice nurses and mental health specialists in improving mental health outcomes of adults in primary care.

DESIGN

This study used a systematic review of randomized controlled trials.

DATA SOURCES

Articles from the databases CINAHL, MEDLINE, APA PsycInfo, PubMed, EMBASE, Cochrane EBM Reviews, Web of Science Core Collection, and ProQuest Dissertation and Thesis published between 2000 and 2020 were included.

REVIEW METHODS

The review was arranged based on the Cochrane Collaboration guidelines and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).

RESULTS

Twelve articles met the eligibility criteria. Eight studies revealed that nurse-led intervention was significantly superior to its comparator. The review identified three major themes: training and supervision, single and collaborative care and psychosocial treatments.

CONCLUSION

Nurses could be temporarily employed to provide mental health services in the absence of mental health specialists as long as appropriate training and supervision was provided. This finding should be interpreted with caution due to the high risk of bias in the studies reviewed and the limited generalisability of their findings.

Personalized care planning and shared decision making in collaborative care programs for depression and anxiety disorders: A systematic review

BACKGROUND

Collaborative care is an evidence-based approach to improving outcomes for common mental disorders in primary care. Efforts are underway to broadly implement the collaborative care model, yet the extent to which this model promotes person-centered mental health care has been little studied. The aim of this study was to describe practices related to two patient and family engagement strategies-personalized care planning and shared decision making-within collaborative care programs for depression and anxiety disorders in primary care.

METHODS

We conducted an update of a 2012 Cochrane review, which involved searches in Cochrane CCDAN and CINAHL databases, complemented by additional database, trial registry, and cluster searches. We included programs evaluated in a clinical trials targeting adults or youth diagnosed with depressive or anxiety disorders, as well as sibling reports related to these trials. Pairs of reviewers working independently selected the studies and data extraction for engagement strategies was guided by a codebook. We used narrative synthesis to report on findings.

RESULTS

In total, 150 collaborative care programs were analyzed. The synthesis showed that personalized care planning or shared decision making were practiced in fewer than half of programs. Practices related to personalized care planning, and to a lesser extent shared decision making, involved multiple members of the collaborative care team, with care managers playing a pivotal role in supporting patient and family engagement. Opportunities for quality improvement were identified, including fostering greater patient involvement in collaborative goal setting and integrating training and decision aids to promote shared decision making.

CONCLUSION

This review suggests that personalized care planning and shared decision making could be more fully integrated within collaborative care programs for depression and anxiety disorders. Their absence in some programs is a missed opportunity to spread person-centered mental health practices in primary care.

The care manager meeting the patients' unique needs using the care manager model-A qualitative study of experienced care managers

Background

Implementation of a care manager in a collaborative care team in Swedish primary care via a randomized controlled trial showed successful outcome. As four years have elapsed since the implementation of care managers, it is important to gain knowledge about the care managers’ long-term skills and experiences. The purpose was to examine how long-term experienced care managers perceived and experienced their role and how they related to and applied the care manager model.

Method

Qualitative study with a focus group and interviews with nine nurses who had worked for more than two years as care managers for common mental disorders. The analysis used Systematic Text Condensation.

Results

Four codes arose from the analysis: Person-centred; Acting outside the comfort zone; Successful, albeit some difficulties; Pride and satisfaction. The care manager model served as a handrail for the care manager, providing a trustful and safe environment. Difficulties sometimes arose in the collaboration with other professionals.

Conclusion

This study shows that long-term experience of working as a care manager contributed to an in-depth insight and understanding of the care manager model and enabled care managers to be flexible and act outside the comfort zone when providing care and support to the patient. A new concept emerged during the analytical process, i.e. the Anchored Care Manager, which described the special competencies gained through experience.

Implementation of a care manager organisation and its association with antidepressant medication patterns: a register-based study of primary care centres in Sweden

OBJECTIVE

To evaluate the implementation of a care manager organisation for common mental disorders and its association with antidepressant medication patterns on primary care centre (PCC) level, compared with PCCs without this organisation. Moreover, to determine whether a care manager organisation is associated with antidepressant medication patterns that is more in accordance with treatment guidelines.

DESIGN

Register-based study on PCC level.

SETTING

Primary care in Region Västra Götaland, Sweden.

PARTICIPANTS

All PCCs in the region. PCCs were analysed in three subgroups: PCCs with a care manager organisation during 2015 and 2016 (n=68), PCCs without the organisation (n=92) and PCCs that shifted to a care manager organisation during 2016 (n=42).

OUTCOME MEASURES

Proportion of inadequate medication users, defined as number of patients >18 years with a common mental disorder diagnosis receiving care at a PCC in the region during the study period and dispensed 1-179 defined daily doses (DDD) of antidepressants of total patients with at least 1 DDD. The outcome was analysed through generalised linear regression and a linear mixed-effects model.

RESULTS

Overall, all PCCs had about 30%-34% of inadequate medication users. PCCs with a care manager organisation had significantly lower proportion of inadequate medication users in 2016 compared with PCCs without (-6.4%, p=0.02). These differences were explained by higher proportions in privately run PCCs. PCCs that shifted to a care manager organisation had a significant decrease in inadequate medication users over time (p=0.01).

CONCLUSIONS

Public PCCs had a more consistent antidepressant medication pattern compared with private PCCs that gained more by introducing a care manager organisation. It was possible to document a significant decrease in inadequate medication users, notwithstanding that PCCs in the region followed the guidelines to a comparatively high extent regardless of present care manager organisation.

Resource allocation for depression management in general practice: A simple data-based filter model

Background

This study aimed to illustrate the potential utility of a simple filter model in understanding the patient outcome and cost-effectiveness implications for depression interventions in primary care.

Methods

Modelling of hypothetical intervention scenarios during different stages of the treatment pathway was conducted.

Results

Three scenarios were developed for depression related to increasing detection, treatment response and treatment uptake. The incremental costs, incremental number of successes (i.e., depression remission) and the incremental costs-effectiveness ratio (ICER) were calculated. In the modelled scenarios, increasing provider treatment response resulted in the greatest number of incremental successes above baseline, however, it was also associated with the greatest ICER. Increasing detection rates was associated with the second greatest increase to incremental successes above baseline and had the lowest ICER.

Conclusions

The authors recommend utility of the filter model to guide the identification of areas where policy stakeholders and/or researchers should invest their efforts in depression management.

The experiences of care managers and rehabilitation coordinators of a primary care intervention to promote return to work for patients with common mental disorders: a qualitative study

BACKGROUND

In an earlier study, PRIM-CARE RCT, a care manager implementation at the primary care centre showed improved return to work and reduced sick leave for patients with CMD. To further improve return to work, the project Co-Work-Care added a person-centered dialogue meeting between the patient, the employer and the rehabilitation coordinator, preceded by an increased collaboration between care manager, rehabilitation coordinator and GP. In this first qualitative study of the Co-Work-Care project, we explored how care managers and rehabilitation coordinators experienced the Co-Work-Care model. The purpose of this study was to explore care managers' and rehabilitation coordinators' perceptions and experiences of a close collaboration and the use of the person-centred dialogue meeting.

METHODS

From an ongoing RCT with 20 primary care centres, care managers (CMs) (n = 13) and rehabilitation coordinators (RCs) (n = 12) participated in a qualitative study with focus groups. The study was conducted in the primary health care in a Swedish region. The data was analysed with Systematic Text Condensation by Malterud.

RESULTS

Seven codes describing the participants' experiences of the Co-Work-Care model were identified: 1) The importance of collaboration at the primary care centre, 2) Collaboration and division of roles between the RC and the CM, 3) Collaboration with the General practitioner (GP), 4) The person-centred dialogue meeting, 5) Initiating the person-centred dialogue meeting, 6) The person-centred dialogue meeting to improve collaboration with the employer, and 7) The person-centred dialogue meeting to teach about the return to work process.

CONCLUSION

The increased collaboration within the Co-Work-Care model created a common picture and understanding of the patient's situation. The person-centred dialogue meeting in the rehabilitation process became a bridge between the employer and the patient.

Factors associated with non-initiation of mental healthcare after detection of poor mental health at a scheduled health check: a cohort study

INTRODUCTION

Poor mental health is an important public health concern, but mental health problems are often under-recognised. Providing feedback to general practitioners (GPs) on their patients' mental health status may improve the identification of cases in need of mental healthcare.

OBJECTIVES

To investigate the extent of initiation of mental healthcare after identification of poor mental health and to identify factors associated with non-initiation.

DESIGN

Prospective cohort study with 1-year follow-up.

SETTING

In a population-based health preventive programme, Check Your Health, we conducted a combined mental and physical health check in Randers Municipality, Denmark, in 2012-2015 in collaboration with local GPs.

PARTICIPANTS

Participants were 350 individuals aged 30-49 years old with screen-detected poor mental health who had not received mental healthcare within the past year. The cohort was derived from 14 167 randomly selected individuals of whom 52% (n=7348) participated. Mental health was assessed by the mental component summary score of the 12-item Short-Form Health Survey.

OUTCOME

The outcome was initiation of mental healthcare. Mental healthcare included psychometric testing by GP, talk therapy by GP, contact with a psychologist, contact with a psychiatrist and psychotropic medication.

RESULTS

Within 1 year, 22% (95% CI 18 to 27) of individuals with screen-detected poor mental health initiated mental healthcare. Among individuals who initiated mental healthcare within follow-up, one in six had visited their GP once or less in the preceding year. Male sex (OR: 0.49 (95% CI 0.28 to 0.86)) and less impaired mental health (OR: 0.93 (95% CI 0.89 to 0.98)) were associated with non-initiation of mental healthcare. We found no overall association between socioeconomic factors and initiating mental healthcare.

CONCLUSION

Systematic provision of mental health test results to GPs may improve the identification of cases in need of mental healthcare, but does not translate into initiation of mental healthcare. Further research should focus on methods to improve initiation of mental healthcare, especially among men.

The Effectiveness of Patient-Centred Medical Home-Based Models of Care versus Standard Primary Care in Chronic Disease Management: A Systematic Review and Meta-Analysis of Randomised and Non-Randomised Controlled Trials

Patient-centred care by a coordinated primary care team may be more effective than standard care in chronic disease management. We synthesised evidence to determine whether patient-centred medical home (PCMH)-based care models are more effective than standard general practitioner (GP) care in improving biomedical, hospital, and economic outcomes. MEDLINE, CINAHL, Embase, Cochrane Library, and Scopus were searched to identify randomised (RCTs) and non-randomised controlled trials that evaluated two or more principles of PCMH among primary care patients with chronic diseases. Study selection, data extraction, quality assessment using Joanna Briggs Institute (JBI) appraisal tools, and grading of evidence using Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach were conducted independently. A quantitative synthesis, where possible, was pooled using random effects models and the effect size estimates of standardised mean differences (SMDs) and odds ratios (ORs) with 95% confidence intervals were reported. Of the 13,820 citations, we identified 78 eligible RCTs and 7 quasi trials which included 60,617 patients. The findings suggested that PCMH-based care was associated with significant improvements in depression episodes (SMD -0.24; 95% CI -0.35, -0.14; I2 = 76%) and increased odds of remission (OR 1.79; 95% CI 1.46, 2.21; I2 = 0%). There were significant improvements in the health-related quality of life (SMD 0.10; 95% CI 0.04, 0.15; I2 = 51%), self-management outcomes (SMD 0.24; 95% CI 0.03, 0.44; I2 = 83%), and hospital admissions (OR 0.83; 95% CI 0.70, 0.98; I2 = 0%). In terms of biomedical outcomes, with exception to total cholesterol, PCMH-based care led to significant improvements in blood pressure, glycated haemoglobin, and low-density lipoprotein cholesterol outcomes. The incremental cost of PCMH care was identified to be small and significantly higher than standard care (SMD 0.17; 95% CI 0.08, 0.26; I2 = 82%). The quality of individual studies ranged from "fair" to "good" by meeting at least 60% of items on the quality appraisal checklist. Additionally, moderate to high heterogeneity across studies in outcomes resulted in downgrading the included studies as moderate or low grade of evidence. PCMH-based care has been found to be superior to standard GP care in chronic disease management. Results of the review have important implications that may inform patient, practice, and policy-level changes.

Transition Cliffs for Young Adults with Anxiety and Depression: Is Integrated Mental Health Care a Solution?

Young adulthood is a major transition period, particularly challenging for those with mental disorders. Though the prevalence of depressive and anxiety disorders is especially high, young adults are less likely to receive mental health treatment than younger and older individuals. Reasons for this mental health treatment gap are multifold and range from individual- to system-level factors that must be taken into consideration when addressing young adult mental health needs. Studies in adults and adolescents have shown that integrated care in primary care settings is an effective model of treatment of mental disorders. After providing an overview of the mental health treatment gap in this developmental period, the argument is made for research focused on integrated care models specifically tailored for young adults that takes into consideration the various needs and challenges that they face and addresses the mental health treatment gap in young adulthood.

Improving depression outcomes among Australian primary care patients: protocol for a cluster randomised controlled trial

INTRODUCTION

Depression is a common and debilitating condition. In Australia, general practitioners (GPs) are the key providers of depression care. However, available evidence suggests that case finding for depression in primary care is poor. This study will examine whether a systematic approach to screening for depression and assessing patient preferences for depression care improves depression outcomes among primary care patients.

METHODS AND ANALYSIS

A cluster randomised controlled design will be used with general practice clinics randomly assigned to either the intervention (n=12) or usual care group (n=12). Patients who are aged 18 and older, presenting for general practice care, will be eligible to participate. Eighty-three participants will be recruited at each clinic. Participants will be asked to complete a baseline survey administered on a touch screen computer at their GP clinic, and then a follow-up survey at 3, 6 and 12 months. Those attending usual care practices will receive standard care. GPs at intervention practices will complete an online Clinical e-Audit, and will be provided with provider and patient-directed resources for depression care. Patients recruited at intervention practices who score 10 or above on the Patient Health Questionnaire-9 will have feedback regarding their depression screening results and preferences for care provided to their GP. The primary analysis will compare the number of cases of depression between the intervention and control groups.

ETHICS AND DISSEMINATION

The study has been approved by the University of Newcastle Human Research Ethics Committee, and registered with Human Research Ethics Committees of the University of Wollongong, Monash University and University of New South Wales. Results will be disseminated through peer-reviewed journal publications and conference presentations.

Newly educated care managers' experiences of providing care for persons with stress-related mental disorders in the clinical primary care context

Objective

Our aim was to explore how the care managers put the complex care manager task into practice and how they perceived their task, which was to facilitate effective, person-centred treatment for stress-related disorder concordant with evidence-based guidelines in primary care.

Design

This was a qualitative study using examination reports from the course for care managers. Systematic text condensation according to Malterud was used for the analysis.

Setting

Primary health care centres

Subject

Twenty-eight newly educated care managers in primary health care participated in the study. The median age was 50 (31–68) years. Twenty-seven were women and one was a man. Twenty-one were employed as nurses and seven as counsellors.

Results

The informants perceived the role as care manager as meaningful but at times complicated. To participate in teams and to work closely with the general practitioner was experienced as important. The co-ordinating function was emphasised as especially important, as well as the increased continuity in care. The dual role as care manager and counsellor was sometimes experienced as problematic.

Conclusion

The informants took advantage of the knowledge they had attained during the course. They perceived themselves as being a bridge between patients and other professionals. The result of having dual roles at the primary health care centre unexpectedly revealed difficulties for some professionals. The nurses seemed more familiar with the new way of working.

Care managers can be useful for patients with depression but their role must be clear: a qualitative study of GPs' experiences

Objective: Explore general practitioners' (GPs') views on and experiences of working with care managers for patients treated for depression in primary care settings. Care managers are specially trained health care professionals, often specialist nurses, who coordinate care for patients with chronic diseases. Design: Qualitative content analysis of five focus-group discussions. Setting: Primary health care centers in the Region of Västra Götaland and Dalarna County, Sweden. Subjects: 29 GPs. Main outcome measures: GPs' views and experiences of care managers for patients with depression. Results: GPs expressed a broad variety of views and experiences. Care managers could ensure care quality while freeing GPs from case management by providing support for patients and security and relief for GPs and by coordinating patient care. GPs could also express concern about role overlap; specifically, that GPs are already care managers, that too many caregivers disrupt patient contact, and that the roles of care managers and psychotherapists seem to compete. GPs thought care managers should be assigned to patients who need them the most (e.g. patients with life difficulties or severe mental health problems). They also found that transition to a chronic care model required change, including alterations in the way GPs worked and changes that made depression treatment more like treatment for other chronic diseases. Conclusion: GPs have varied experiences of care managers. As a complementary part of the primary health care team, care managers can be useful for patients with depression, but team members' roles must be clear. KEY POINTS A growing number of primary health care centers are introducing care managers for patients with depression, but knowledge about GPs' experiences of this kind of collaborative care is limited. GPs find that care managers provide support for patients and security and relief for GPs. GPs are concerned about potential role overlap and desire greater latitude in deciding which patients can be assigned a care manager. GPs think depression can be treated using a chronic care model that includes care managers but that adjusting to the new way of working will take time.

Process evaluation of a cluster randomised intervention in Swedish primary care: using care managers in collaborative care to improve care quality for patients with depression

Background

The collaborative care model with a care manager has previously generated beneficial results for patients with depression in terms of decreased burden of depression symptoms. A care manager function has been tested in Sweden in the PRIM-CARE RCT with successful results. The aim of the present study was to evaluate the process of implementing care managers in collaborative care for patients with depression in Swedish primary health care in the PRIM-CARE RCT.

Methods

The study followed UK Medical Research Council guidance for process evaluation.

Field notes from the implementation of the PRIM - CARE RCT were used, as well as data collected from five focus group discussions with General Practitioners (n = 29) and three focus group discussions with care managers (n = 11). Data were analysed with content analysis.

Results

Training sessions, careful preparation and extensive initial support to the care manager and staff at the Primary Care Centres were important ingredients in the implementation. The close access to facilitators, the recurrent peer support meetings, and the weekly newsletter strengthened the care manager function.

Conclusions

A complex intervention adapted to the Swedish primary care context focusing on a care manager function for patients with depression could be performed through a stepwise implementation process. Financial support from the health care regions included in the study helped to reduce the impact of identified barriers. This process evaluation has revealed new and important knowledge for primary care development concerning infrastructure and organization building, knowledge sharing, and facilitating factors and barriers.

Sex Differences In Psychoeducation For Patients With Depression: A Comparison Of Frequency And Efficacy Of Psychoeducation

BACKGROUND

We aimed to reveal sex differences in depression comprehension by reanalyzing data from a previous study of patients who were administered antidepressants.

METHODS

A total of 424 outpatients were enrolled in the study. Participants were provided an original self-administered questionnaire that comprised eight items: depressive symptoms, course of depression, cause of depression, treatment plan, duration of antidepressant use, how to discontinue antidepressants, side effects of antidepressants, and psychotherapy. Each item consisted of the following two questions: "Have you received an explanation from the doctor in charge?" and "How much do you understand about your treatment?" The level of patients' comprehension of these questions was rated on a scale of 0-10 (11 anchor points). Symptoms were evaluated using the Quick Inventory for Depressive Symptomatology, Japanese version, and other scales. Patients were divided on the basis of sex, regardless of whether they were in remission.

RESULTS

Compared with male patients, female patients with depression exhibited lower levels of depression and did not receive adequate psychoeducation from their physicians. While depression comprehension of female patients might not necessarily be associated with remission, male patients in remission received more explanations about depression and understood more compared with female patients.

CONCLUSION

Depression comprehension of male patients might be associated with remission, and psychoeducation should be sex-oriented to improve treatment responses.

Cost-effectiveness of a care manager collaborative care programme for patients with depression in primary care: economic evaluation of a pragmatic randomised controlled study

OBJECTIVE

To evaluate the cost-effectiveness of a care manager (CM) programme compared with care as usual (CAU) for treatment of depression at primary care centres (PCCs) from a healthcare as well as societal perspective.

DESIGN

Cost-effectiveness analysis.

SETTING

23 PCCs in two Swedish regions.

PARTICIPANTS

Patients with depression (n=342).

MAIN OUTCOME MEASURES

A cost-effectiveness analysis was applied on a cluster randomised trial at PCC level where patients with depression had 3 months of contact with a CM (11 intervention PCCs, n=163) or CAU (12 control PCCs, n=179), with follow-up 3 and 6 months. Effectiveness measures were based on the number of depression-free days (DFDs) calculated from the Montgomery-Åsberg Depression Rating Scale-Self and quality-adjusted life years (QALYs). Results were expressed as the incremental cost-effectiveness ratio: ∆Cost/∆QALY and ∆Cost/∆DFD. Sampling uncertainty was assessed based on non-parametric bootstrapping.

RESULTS

Health benefits were higher in intervention group compared with CAU group: QALYs (0.357 vs 0.333, p<0.001) and DFD reduction of depressive symptom score (79.43 vs 60.14, p<0.001). The mean costs per patient for the 6-month period were €368 (healthcare perspective) and €6217 (societal perspective) for the intervention patients and €246 (healthcare perspective) and €7371 (societal perspective) for the control patients (n.s.). The cost per QALY gained was €6773 (healthcare perspective) and from a societal perspective the CM programme was dominant.

DISCUSSION

The CM programme was associated with a gain in QALYs as well as in DFD, while also being cost saving compared with CAU from a societal perspective. This result is of high relevance for decision-makers on a national level, but it must be observed that a CM programme for depression implies increased costs at the primary care level.

Interventions to Increase Depression Treatment Initiation in Primary Care Patients: a Systematic Review

INTRODUCTION

Nearly 50% of depressed primary care patients referred to mental health services do not initiate mental health treatment. The most promising interventions for increasing depression treatment initiation in primary care settings remain unclear.

METHODS

We performed a systematic search of publicly available databases from inception through August 2017 to identify interventions designed to increase depression treatment initiation. Two authors independently selected, extracted data, and rated risk of bias from included studies. Eligible studies used a randomized or pre-post design and assessed depression treatment initiation (i.e., ≥ 1 mental health visit or antidepressant fill) among adults, the majority of whom met criteria for depression. Interventions were classified as simple or complex and sub-classified into intervention strategies that were graded for strength of evidence.

RESULTS

Of 9516 articles identified, we included 14 unique studies representing 16 (4 simple and 12 complex) interventions and 8 treatment initiation strategies. We found low to moderate strength of evidence for collaborative/integrated care (3 studies), treatment preference matching (2 studies), and case management (2 studies) strategies. However, there was insufficient evidence to determine the benefit of cultural tailoring (2 studies), motivation (alone, with reminders or with cultural tailoring (5 studies)), education (1 study), and shared decision-making strategies (1 study). Overall, we found moderate strength of evidence for complex interventions (8 of 12 complex interventions demonstrated statistically significant effects on treatment initiation).

DISCUSSION

Collaborative/integrated care, preference treatment matching, and case management strategies had the best evidence for improving depression treatment initiation, but none of the strategies had high strength of evidence. While primary care settings can consider using some of these strategies when referring depressed patients to treatment, our review highlights the need for further rigorous research in this area.

Sustainability of collaborative care management for depression in primary care settings with academic affiliations across New York State

Background

In a large statewide initiative, New York State implemented collaborative care (CC) from 2012 to 2014 in 32 primary care settings where residents were trained and supported its sustainability through payment reforms implemented in 2015. Twenty-six clinics entered the sustainability phase and six opted out, providing an opportunity to examine factors predicting continued CC participation and fidelity.

Methods

We used descriptive statistics to assess implementation metrics in sustaining vs. opt-out clinics and trends in implementation fidelity 1 and 2 years into the sustainability phase among sustaining clinics. To characterize barriers and facilitators, we conducted 31 semi-structured interviews with psychiatrists, clinic administrators, primary care physicians, and depression care managers (24 at sustaining, 7 at opt-out clinics).

Results

At the end of the implementation phase, clinics opting to continue the program had significantly higher care manager full-time equivalents (FTEs) and achieved greater clinical improvement rates (46% vs. 7.5%, p = 0.004) than opt-out clinics. At 1 and 2 years into sustainability, the 26 sustaining clinics had steady rates of depression screening, staffing FTEs and treatment titration rates, significantly higher contacts/patient and improvement rates and fewer enrolled patients/FTE.

During the sustainability phase, opt-out sites reported lower patient caseloads/FTE, psychiatry and care manager FTEs, and physician/psychiatrist CC involvement compared to sustaining clinics. Key barriers to sustainability noted by respondents included time/resources/personnel (71% of respondents from sustaining clinics vs. 86% from opt-out), patient engagement (67% vs. 43%), and staff/provider engagement (50% vs. 43%). Fewer respondents mentioned early implementation barriers such as leadership support, training, finance, and screening/referral logistics. Facilitators included engaging patients (e.g., warm handoffs) (79% vs. 86%) and staff/providers (71% vs. 100%), and hiring personnel (75% vs. 57%), particularly paraprofessionals for administrative tasks (67% vs. 0%).

Conclusions

Clinics that saw early clinical improvement and who invested in staffing FTEs were more likely to elect to enter the sustainability phase. Structural rules (e.g., payment reform) both encouraged participation in the sustainability phase and boosted long-term outcomes. While limited to settings with academic affiliations, these results demonstrate that patient and provider engagement and care manager resources are critical factors to ensuring sustainability.

The Association Between the Severity and Level of Understanding of Depression Among Patients Treated With Antidepressants: A Survey of 424 Outpatients in Japan

OBJECTIVES

The present study investigated the association between the severity and knowledge of depression and attempted to reveal the specific aspects of understanding associated with severity.

METHODS

A total of 424 outpatients were enrolled in this study. We used an original self-administered questionnaire: (a) the symptoms of depression, (b) the course of depression, (c) the cause of depression, (d) the treatment plan, (e) the duration of antidepressant use, (f) how to discontinue antidepressant use, (g) the adverse effects of antidepressants, and (h) psychotherapy. Each category consisted of the following questions: "How much do you understand about your treatment?" The level of understanding was rated on an 11-point scale ranging from 0 to 10. The following scales were administered: the Quick Inventory of Depressive Symptomatology, Japanese version (QIDS-J); the Global Assessment of Functioning; and the Clinical Global Impression, Severity scale. Subjects were divided in 5 groups according to severity of QIDS-J. Clinical characteristics were also investigated.

RESULTS

Based on an analysis of variance, significant differences were found among the 5 groups with regard to age at onset, duration of disease, and duration of antidepressant use. A multiple regression analysis revealed that item B significantly and negatively predicted the QIDS-J scores, whereas item C significantly and positively predicted these scores. Some multiple logistic regression models seeking to distinguish severity found that all but items E to H were significantly associated with severity.

CONCLUSIONS

Items B and C were significantly negatively and positively associated with depression severity, respectively. Sufficient and suitable psychoeducation in and knowledge of depression might improve the treatment responses in patients with depression.

Elusive search for effective provider interventions: a systematic review of provider interventions to increase adherence to evidence-based treatment for depression

Background

Depression is a common mental health disorder for which clinical practice guidelines have been developed. Prior systematic reviews have identified complex organizational interventions, such as collaborative care, as effective for guideline implementation; yet, many healthcare delivery organizations are interested in less resource-intensive methods to increase provider adherence to guidelines and guideline-concordant practices. The objective of this systematic review was to assess the effectiveness of healthcare provider interventions that aim to increase adherence to evidence-based treatment of depression in routine clinical practice.

Methods

We searched five databases through August 2017 using a comprehensive search strategy to identify English-language randomized controlled trials (RCTs) in the quality improvement, implementation science, and behavior change literature that evaluated outpatient provider interventions, in the absence of practice redesign efforts, to increase adherence to treatment guidelines or guideline-concordant practices for depression. We used meta-analysis to summarize odds ratios, standardized mean differences, and incidence rate ratios, and assessed quality of evidence (QoE) using the GRADE approach.

Results

Twenty-two RCTs promoting adherence to clinical practice guidelines or guideline-concordant practices met inclusion criteria. Studies evaluated diverse provider interventions, including distributing guidelines to providers, education/training such as academic detailing, and combinations of education with other components such as targeting implementation barriers. Results were heterogeneous and analyses comparing provider interventions with usual clinical practice did not indicate a statistically significant difference in guideline adherence across studies. There was some evidence that provider interventions improved individual outcomes such as medication prescribing and indirect comparisons indicated more complex provider interventions may be associated with more favorable outcomes. We did not identify types of provider interventions that were consistently associated with improvements across indicators of adherence and across studies. Effects on patients’ health in these RCTs were inconsistent across studies and outcomes.

Conclusions

Existing RCTs describe a range of provider interventions to increase adherence to depression guidelines. Low QoE and lack of replication of specific intervention strategies across studies limited conclusions that can be drawn from the existing research. Continued efforts are needed to identify successful strategies to maximize the impact of provider interventions on increasing adherence to evidence-based treatment for depression.

The characteristics of understanding of depression among older patients treated with antidepressants: a comparison between older and younger patients

BACKGROUND

To reveal characteristics of understanding of depression among older patients, we reanalyzed the data from a previous study of patients who were administered antidepressants.

METHODS

A total of 424 outpatients were enrolled in this study. We used an original self-administered questionnaire consisting of eight items: depressive symptoms, the course of depression, the cause of depression, the treatment plan, the duration of antidepressant use, how to discontinue antidepressants, the side effects of antidepressants, and psychotherapy. Each item consisted of the following two questions: "Have you received an explanation from the doctor in charge?" and "How much do you understand about your treatment?". The level of understanding was rated on a scale of 0-10 (11 anchor points). Subjects were divided into two groups: younger patients who were <65 years of age and older patients who were ≥65 years of age.

RESULTS

Older patients with depression showed lower levels of understanding of depression and did not receive sufficient psychoeducation from their physicians, but their understanding of depression might not be associated with their remission. In the younger group, the scores of understanding of the course of depression, the treatment plan, how to discontinue antidepressants, and psychotherapy items, and the total understanding score of remitters, were significantly higher than those of non-remitters. In contrast, there were no significant differences in the items score or total score between remitters and non-remitters in the older group.

CONCLUSION

Older patients showed lower levels of understanding of depression and did not appear to receive sufficient psychoeducation, but their understanding of depression might not be associated with their remission.

Implementation of depression and anxiety screening in patients undergoing radiotherapy

Anxiety and depression are disabling, underdiagnosed issues that affect the management of oncology patients. Until recently, there has been no standard protocol for screening and treating these ailments at our cancer centre. The purpose of this institutional review board-approved study was to analyse the implementation of a screening tool in our clinical workflow with the aim of screening over 90% of patients and increasing referrals to mental health services by 50%.

Clinical effectiveness of care managers in collaborative care for patients with depression in Swedish primary health care: a pragmatic cluster randomized controlled trial

Background

Depression is one of the leading causes of disability and affects 10-15% of the population. The majority of people with depressive symptoms seek care and are treated in primary care. Evidence internationally for high quality care supports collaborative care with a care manager. Our aim was to study clinical effectiveness of a care manager intervention in management of primary care patients with depression in Sweden.

Methods

In a pragmatic cluster randomized controlled trial 23 primary care centers (PCCs), urban and rural, included patients aged ≥ 18 years with a new (< 1 month) depression diagnosis. Intervention consisted of Care management including continuous contact between care manager and patient, a structured management plan, and behavioral activation, altogether around 6-7 contacts over 12 weeks. Control condition was care as usual (CAU). Outcome measures: Depression symptoms (measured by Mongomery-Asberg depression score-self (MADRS-S) and BDI-II), quality of life (QoL) (EQ-5D), return to work and sick leave, service satisfaction, and antidepressant medication. Data were analyzed with the intention-to-treat principle.

Results

One hundred ninety two patients with depression at PCCs with care managers were allocated to the intervention group, and 184 patients at control PCCs were allocated to the control group. Mean depression score measured by MADRS-S was 2.17 lower in the intervention vs. the control group (95% CI [0.56; 3.79], p = 0.009) at 3 months and 2.27 lower (95% CI [0.59; 3.95], p = 0.008) at 6 months; corresponding BDI-II scores were 1.96 lower (95% CI [− 0.19; 4.11], p = 0.07) in the intervention vs. control group at 6 months. Remission was significantly higher in the intervention group at 6 months (61% vs. 47%, p = 0.006). QoL showed a steeper increase in the intervention group at 3 months (p = 0.01). During the first 3 months, return to work was significantly higher in the intervention vs. the control group. Patients in the intervention group were more consistently on antidepressant medication than patients in the control group.

Conclusions

Care managers for depression treatment have positive effects on depression course, return to work, remission frequency, antidepressant frequency, and quality of life compared to usual care and is valued by the patients.

Timing of psychoeducation for patients with depression who were treated with antidepressants: when should patients receive psychoeducation

BACKGROUND

We analyzed data on the understanding of depression among patients who were prescribed antidepressants to determine when psychoeducation should be provided.

PATIENTS AND METHODS

A total of 424 outpatients were enrolled in this study. We used an original self-administered questionnaire consisting of eight categories: (A) depressive symptoms, (B) the course of depression, (C) causes of depression, (D) the treatment plan, (E) the duration of antidepressant use, (F) discontinuation of antidepressants, (G) the side effects of antidepressants, and (H) psychotherapy. Each category was assessed with the following two questions: "Have you received an explanation of this topic from the doctor in charge?" and "How much do you understand about your treatment?" The level of understanding of patients was rated on a scale from 0 to 10 (no understanding to full understanding; 11 anchor points). Symptoms were evaluated using the Quick Inventory for Depressive Symptomatology, Japanese version (QIDS-J) and other scales. Participants were divided into two groups: patients receiving psychoeducation at their first visit vs patients receiving psychoeducation after their first visit.

RESULTS

Of the patients who had received an explanation of each psychoeducation item, a greater proportion were in the first visit group than in the after first visit group for nearly all items. Compared with the after first visit group, the first visit group showed a better understanding of each psychoeducation item and significantly lower QIDS scores for those receiving explanations of Items A and C. There was no significant difference between the two groups in remittance rates.

CONCLUSION

Psychoeducation on depression, especially regarding the symptoms and causes of depression, should be provided at patients' first visit.

A Randomized Trial of Off-Site Collaborative Care for Depression in Chronic Hepatitis C Virus

OBJECTIVE

To test the effectiveness of a collaborative depression care model in improving depression and hepatitis C virus (HCV) care.

DATA SOURCES/STUDY SETTING

Hepatitis C virus clinic patients who screened positive for depression at four Veterans Affairs Hospitals.

STUDY DESIGN

We compared off-site depression collaborative care (delivered by depression care manager, pharmacist, and psychiatrist) with usual care in a randomized trial. Primary depression outcomes were treatment response (≥50 percent decrease in 20-item Hopkins Symptoms Checklist [SCL-20] score), remission (mean SCL-20 score, <0.5), and depression-free days (DFDs). Primary HCV outcome was receipt of HCV treatment.

DATA COLLECTION

Patient data were collected by self-report telephone surveys at baseline and 12 months, and from electronic medical records.

PRINCIPAL FINDINGS

Baseline screening identified 292 HCV-infected patients with depression, and 242 patients completed 12-month follow-up (82.9 percent). Intervention participants were more likely to report depression treatment response, remission, and more DFDs than usual care participants. Intervention participants were more likely to receive antiviral treatment; however, the difference was not statistically significant.

CONCLUSION

Off-site depression collaborative care improved depression outcomes in HCV patients and may serve as a model for collaboration between mental health and specialty physical health providers in other high co-occurring conditions.

Examination of a Nurse-led Community-based Education and Coaching Intervention for Coronary Heart Disease High-risk Individuals in China

PURPOSE

Early detection and management of coronary heart disease (CHD) are embedded into many community health service and primary care practices in western countries. The Framingham CHD risk score has been used to predict CHD and mortality for nearly 20 years, and it has predicted CHD event risk accurately in multiethnic populations. The aim of this study was to access the effect of a 6-month community-based intervention on CHD risk in individuals at high risk.

METHODS

A randomized controlled trial of individuals with a high 10-year CHD risk were recruited from two communities in China. Individuals in the intervention group (n = 53) received a 3-month group education and a 3-month coaching session. Physical examination and self-report questionnaires were used to collect both pre- and postintervention data on blood pressure, glucose, cholesterol, body mass index, smoking, depression, and health-related quality of life (HRQoL).

RESULTS

A total of 102 participants (85.0%) completed the 6-month study. Compared with the usual care group, the intervention group had a 5 mmHg greater reduction in systolic blood pressure (t = 2.01, p = .047), larger declines in glucose (t = -2.49, p = .015), cholesterol (t = -2.44, p = .017), body mass index (t = -2.58, p = .011), and depression (t = -2.05, p = .043), and better reports of HRQoL (t = 3.36, p = .001). No significant group differences in smoking behaviors were reported.

CONCLUSION

A 6-month community-based intervention in a CHD high-risk population improved disease-related risk factors, depression, and HRQoL. Results provide preliminary evidence for primary prevention of cardiovascular disease risk in a community high-risk population.

Consistency and sources of divergence in recommendations on screening with questionnaires for presently experienced health problems or symptoms: a comparison of recommendations from the Canadian Task Force on Preventive Health Care, UK National Screening Committee, and US Preventive Services Task Force

BACKGROUND

Recently, health screening recommendations have gone beyond screening for early-stage, asymptomatic disease to include "screening" for presently experienced health problems and symptoms using self-report questionnaires. We examined recommendations from three major national guideline organizations to determine the consistency of recommendations, identify sources of divergent recommendations, and determine if guideline organizations have identified any direct randomized controlled trial (RCT) evidence for the effectiveness of questionnaire-based screening.

METHODS

We reviewed recommendation statements listed by the Canadian Task Force on Preventive Health Care (CTFPHC), the United Kingdom National Screening Committee (UKNSC), and the United States Preventive Services Task Force (USPSTF) as of 5 September 2016. Eligible recommendations focused on using self-report questionnaires to identify patients with presently experienced health problems or symptoms. Within each recommendation and accompanying evidence review we identified screening RCTs.

RESULTS

We identified 22 separate recommendations on questionnaire-based screening, including three CTFPHC recommendations against screening, eight UKNSC recommendations against screening, four USPSTF recommendations in favor of screening (alcohol misuse, adolescent depression, adult depression, intimate partner violence), and seven USPSTF recommendations that did not recommend for or against screening. In the four cases where the USPSTF recommended screening, either the CTFPHC, the UKNSC, or both recommended against. When recommendations diverged, the USPSTF expressed confidence in benefits based on indirect evidence, evaluated potential harms as minimal, and did not consider cost or resource use. CTFPHC and UKNSC recommendations against screening, on the other hand, focused on the lack of direct evidence of benefit and raised concerns about harms to patients and resource use. Of six RCTs that directly evaluated screening interventions, five did not report any statistically significant primary or secondary health outcomes in favor of screening, and one trial reported equivocal results.

CONCLUSIONS

Only the USPSTF has made any recommendations for screening with questionnaires for presently experienced problems or symptoms. The CTFPHC and UKNSC recommended against screening in all of their recommendations. Differences in recommendations appear to reflect differences in willingness to assume benefit from indirect evidence and different approaches to assessing possible harms and resource consumption. There were no examples in any recommendations of RCTs with direct evidence of improved health outcomes.

Improving Services for Women with Depression in Primary Care Settings

Women have a higher prevalence of depressive disorders compared to men. The current system of care for women with depressive disorders provides significant financial barriers for patients with lower incomes to access mental health services. Primary care systems are used extensively by women and have the potential to diagnose patients at early stages of mental illness and to provide evidence-based treatments, but this potential is largely unfulfilled because of significant system-level barriers inherent in primary care. Recent effectiveness research provides an excellent framework for cost-effectively improving care of depression using stepped care principles and strategies effective for improving care of other chronic conditions. Psychologists have the potential to help implement stepped care models by providing training, consultation and ongoing quality assurance, as well as by delivering collaborative care models of acute-phase treatment and relapse prevention interventions.

Healthcare team training programs aimed at improving depression management in primary care: A systematic review

BACKGROUND

Although evidence from Latin America and the Caribbean suggests that depression can be effectively treated in primary care settings, depression management remains unevenly performed. This systematic review evaluates all the international evidence on healthcare team training programs aimed at improving the outcomes of patients with depression.

METHODS

Three databases were searched for articles in English or Spanish indexed up to November 20, 2014. Studies were included if they fulfilled the following conditions: clinical trials, meta-analyses, or systematic reviews; and if they evaluated a training or educational program intended to improve the management of depression by primary healthcare teams, and assessed change in depressive symptoms, diagnosis or response rates, referral rates, patients' satisfaction and/or quality of life, and the effectiveness of treatments.

RESULTS

Nine studies were included in this systematic review. Five trials tested the effectiveness of multi-component interventions (training included), and the remaining studies evaluated the effectiveness of specific training programs for depression management. All the studies that implemented multi-component interventions were efficacious, and half of the training trials were shown to be effective.

LIMITATIONS

Contribution of training programs alone to the effectiveness of multi-component interventions is yet to be established. The lack of specificity regarding health providers' characteristics might be a confounding factor.

CONCLUSIONS

The review conducted suggests that stand-alone training programs are less effective than multi-component interventions. In applying the evidence gathered from developed countries to Latin America and the Caribbean, these training programs must consider and address local conditions of mental health systems, and therefore multi-component interventions may be warranted.

A randomised controlled trial of the effectiveness of a program for early detection and treatment of depression in primary care

OBJECTIVE

There is considerable uncertainty about whether depression screening programs in primary care may improve outcomes and what specific features of such programs may contribute to success. We tested the effectiveness of a program involving substantial commitment from local mental health services.

METHODS

Prospective, randomised, patient- and evaluator-masked, parallel-group, controlled study. Participants were recruited in several urban primary care practices where they completed the PC-SAD screener and WHOQOL-Bref. Those who screened positive and did not report suicidal ideation (N=115) were randomised to an intervention group (communication of the result and offer of psychiatric evaluation and treatment free of charge; N=56) or a control group (no feedback on test result for 3 months; N=59). After 3 months, 100 patients agreed to a follow-up telephone interview including the administration of the PC-SAD5 and WHOQOL-Bref.

RESULTS

Depression severity and quality of life improved significantly in both groups. Intent-to-treat analysis showed no effect of the intervention. As only 37% of patients randomised to the intervention group actually contacted the study outpatient clinic, we performed a per-protocol analysis to determine whether the intervention, if delivered as planned, had been effective. This analysis revealed a significant positive effect of the intervention on severity of depressive symptoms, and on response and remission rate. Complier average causal effect analysis yielded similar results.

CONCLUSION

Due to the relatively small sample size, our findings should be regarded as preliminary and have limited generalizability. They suggest that there are considerable barriers on the part of many patients to the implementation of depression screening programs in primary care. While such programs can be effective, they should be designed based on the understanding of patients' perspectives.

Depression and Oropharynx Cancer Outcome

BACKGROUND

Studies have shown a modest relationship between depression and mortality in patients with cancer. Our study addressed methodological weaknesses in the literature by restricting the sample to patients with one cancer type, adjusting for factors known to affect outcome, and following up patients for a sufficient period.

METHODS

We prospectively followed patients newly diagnosed with squamous cell oropharyngeal cancer from the start of radiation therapy until death or until date of last clinical visit. All patients were optimally treated with radiation and sometimes chemotherapy. After adjusting for tumor stage, treatment, comorbidities, smoking, excessive alcohol use, and demographic factors, we assessed the effects of baseline self-reported depression on overall survival and recurrence.

RESULTS

One hundred thirty participants were followed for a median of 5 years. The average age was 56 years, and 83% were male. Eighteen participants died during the study and 15 experienced disease recurrence. Self-reported depression was associated with decreased overall survival duration (hazard ratio = 3.6, 95% confidence interval = 1.2-10.8) and disease recurrence (hazard ratio = 3.8, 95% confidence interval = 1.2-12.2) in multivariate analysis. In addition, smoking was associated with disease recurrence.

CONCLUSIONS

Patients with oropharyngeal cancer may benefit from depression screening and evidence-based treatments, if appropriate. Future studies are needed to determine whether depression is an independent prognostic factor of outcome and to elucidate biobehavioral mechanisms involved in patients with oropharyngeal cancer.

Cost-Effectiveness of Collaborative Care for Depression in HIV Clinics

OBJECTIVE

To examine the cost-effectiveness of the HIV Translating Initiatives for Depression Into Effective Solutions (HITIDES) intervention.

DESIGN

Randomized controlled effectiveness and implementation trial comparing depression collaborative care with enhanced usual care.

SETTING

Three Veterans Health Administration HIV clinics in the Southern United States.

SUBJECTS

Two hundred forty-nine HIV-infected patients completed the baseline interview; 123 were randomized to the intervention and 126 to usual care.

INTERVENTION

HITIDES consisted of an offsite HIV depression care team that delivered up to 12 months of collaborative care. The intervention used a stepped-care model for depression treatment, and specific recommendations were based on the Texas Medication Algorithm Project and the VA/Department of Defense Depression Treatment Guidelines.

MAIN OUTCOME MEASURES

Quality-adjusted life years (QALYs) were calculated using the 12-Item Short Form Health Survey, the Quality of Well Being Scale, and by converting depression-free days to QALYs. The base case analysis used outpatient, pharmacy, patient, and intervention costs. Cost-effectiveness was calculated using incremental cost-effectiveness ratios (ICERs) and net health benefit. ICER distributions were generated using nonparametric bootstrap with replacement sampling.

RESULTS

The HITIDES intervention was more effective and cost saving compared with usual care in 78% of bootstrapped samples. The intervention net health benefit was positive and therefore deemed cost-effective using an ICER threshold of $50,000/QALY.

CONCLUSIONS

In HIV clinic settings, this intervention was more effective and cost saving compared with usual care. Implementation of offsite depression collaborative care programs in specialty care settings may be a strategy that not only improves outcomes for patients but also maximizes the efficient use of limited health care resources.

Reduction of patient-reported antidepressant side effects, by type of collaborative care

OBJECTIVE

Antidepressants are effective for treating depression, and collaborative care increases initiation of and adherence to antidepressants. Side effects of antidepressants are common and can adversely affect quality of life. Care managers address antidepressant side effects directly, but the impact of collaborative care on adverse effects is unknown. This secondary data analysis tested the hypothesis that patient-reported antidepressant side effects were lower for depressed patients receiving high-intensity, telemedicine-based collaborative care (TBCC) than for patients receiving low-intensity, practice-based collaborative care (PBCC).

METHODS

This analysis used data from 190 patients enrolled in a pragmatic, multisite, comparative-effectiveness trial from 2007 to 2009 and followed for 18 months. Most patients were female (83%) and Caucasian (80%). The mean age was 50. Patients randomly assigned to PBCC received 12 months of evidence-based care from an on-site primary care provider and nurse care manager. Patients in TBCC received evidence-based care from an on-site primary care provider supported by a nurse care manager available off site by telephone, as well as by a telepharmacist, telepsychologist, and telepsychiatrist. Telephone interviews completed at baseline, six, 12, and 18 months included assessments of sociodemographic characteristics, beliefs about antidepressant treatment, depression severity, psychiatric comorbidity, medications, adherence, and side effects.

RESULTS

With controls for baseline case mix and time-variant medication characteristics, the TBCC group reported significantly fewer side effects at six and 12 months (p=.008 and .002, respectively). The number of antidepressants prescribed increased risk of side effects (p=.02).

CONCLUSIONS

Patients in the TBCC group reported fewer antidepressant-related side effects, which may have contributed to improved quality of life.

The low level of understanding of depression among patients treated with antidepressants: a survey of 424 outpatients in Japan

BACKGROUND

We used self-administered questionnaires to investigate the level of understanding of depression among outpatients who were administered antidepressants.

METHODS

A total of 424 outpatients were enrolled in this study. We used an original self-administered questionnaire that consisted of eight categories: (A) depressive symptoms, (B) the course of depression, (C) the cause of depression, (D) the treatment plan, (E) the duration of taking antidepressants, (F) how to discontinue antidepressants, (G) the side effects of the antidepressants, and (H) psychotherapy. Each category consisted of the following two questions: "Have you received an explanation from the doctor in charge?" and "How much do you understand about it?" The level of understanding was rated on a scale of 0-10 (11 anchor points). The Quick Inventory of Depressive Symptomatology Japanese version, Global Assessment of Functioning, and Clinical Global Impression - Severity scale were administered, and clinical characteristics were investigated.

RESULTS

The percentages of participants who received explanations were as follows: 61.8% for (A), 49.2% for (B), 50.8% for (C), 57.2% for (D), 46.3% for (E), 28.5% for (F), 50.6% for (G), and 36.1% for (H). The level of understanding in participants who received explanations from their physicians was significantly higher compared with patients who did not receive explanations for all evaluated categories. Patient age, age at disease onset, and Global Assessment of Functioning scores were significantly associated with more items compared with the other variables.

CONCLUSION

Psychoeducation is not sufficiently performed. According to the study results, it is possible for patients to receive better psychoeducation and improve their clinical outcomes.

Usefulness of the Patient Health Questionnaire-9 for Korean medical students

OBJECTIVE

Depression may be highly prevalent among medical students, lowering their functioning and quality of life. Using appropriate extant depression scales to screen for depression and determining factors associated with depression can be helpful in managing it. This study examines the validity and reliability of the Patient Health Questionnaire-9 (PHQ-9) for medical students and the relationship between their scores and sociodemographic variables.

METHODS

This study surveyed 174 medical students using demographic questionnaires, the PHQ-9, the Beck Depression Inventory (BDI), the Patient Heath Questionnaire-15 (PHQ-15), the Beck Anxiety Inventory (BAI), and the Perceived Stress Scale (PSS). It calculated the Cronbach's α for internal consistency and Pearson's correlation coefficients for test-retest reliability and convergent validity of the PHQ-9. In order to examine the relationship between depression and demographic variables, this study performed independent t tests, one-way analysis of variance, chi-square, and binary logistic regressions.

RESULTS

The PHQ-9 was reliable (Cronbach's α = 0.837, test-retest reliability, r = 0.650) and valid (r = 0.509-0.807) when employed with medical students. Total scores on the PHQ-9 were significantly higher among low-perceived academic achievers than among high-perceived academic achievers (p < 0.01). Depression was more prevalent in poor-perceived academic achievers than in high-perceived academic achievers. Similarly, poor-perceived academic achievers were at greater risk of depression than were high-perceived academic achievers (odds ratio [95 % confidence interval] 3.686 [1.092-12.439], p < 0.05).

CONCLUSIONS

The PHQ-9 has satisfactory reliability and validity in medical students in South Korea. Depression is related to poor-perceived academic achievement when measured with the PHQ-9. Early screening for depression with the PHQ-9 in medical students and providing prompt management to high scorers may not only be beneficial to students' mental health but also improve their academic performance.

Can team-based care improve patient satisfaction? A systematic review of randomized controlled trials

Background

Team-based approaches to patient care are a relatively recent innovation in health care delivery. The effectiveness of these approaches on patient outcomes has not been well documented. This paper reports a systematic review of the relationship between team-based care and patient satisfaction.

Methods

We searched MEDLINE, EMBASE, Cochrane Library, CINAHL, and PSYCHOINFO for eligible studies dating from inception to October 8, 2012. Eligible studies reported (1) a randomized controlled trial, (2) interventions including both team-based care and non-team-based care (or usual care), and (3) outcomes including an assessment of patient satisfaction. Articles with different settings between intervention and control were excluded, as were trial protocols. The reference lists of retrieved papers were also evaluated for inclusion.

Results

The literature search yielded 319 citations, of which 77 were screened for further full-text evaluation. Of these, 27 articles were included in the systematic review. The 26 trials with a total of 15,526 participants were included in this systematic review. The pooling result of dichotomous data (number of studies: 10) showed that team-based care had a positive effect on patient satisfaction compared with usual care (odds ratio, 2.09; 95% confidence interval, 1.54 to 2.84); however, combined continuous data (number of studies: 7) demonstrated that there was no significant difference in patient satisfaction between team-based care and usual care (standardized mean difference, −0.02; 95% confidence interval, −0.40 to 0.36).

Conclusions

Some evidence showed that team-based care is better than usual care in improving patient satisfaction. However, considering the pooling result of continuous data, along with the suboptimal quality of included trials, further large-scale and high-quality randomized controlled trials comparing team-based care and usual care are needed.

An interprofessional nurse-led mental health promotion intervention for older home care clients with depressive symptoms

Background

Depressive symptoms in older home care clients are common but poorly recognized and treated, resulting in adverse health outcomes, premature institutionalization, and costly use of health services. The objectives of this study were to examine the feasibility and acceptability of a new six-month interprofessional (IP) nurse-led mental health promotion intervention, and to explore its effects on reducing depressive symptoms in older home care clients (≥ 70 years) using personal support services.

Methods

A prospective one-group pre-test/post-test study design was used. The intervention was a six-month evidence-based depression care management strategy led by a registered nurse that used an IP approach. Of 142 eligible consenting participants, 98 (69%) completed the six-month and 87 (61%) completed the one-year follow-up. Outcomes included depressive symptoms, anxiety, health-related quality of life (HRQoL), and the costs of use of all types of health services at baseline and six-month and one-year follow-up. An interpretive descriptive design was used to explore clients’, nurses’, and personal support workers’ perceptions about the intervention’s appropriateness, benefits, and barriers and facilitators to implementation.

Results

Of the 142 participants, 56% had clinically significant depressive symptoms, with 38% having moderate to severe symptoms. The intervention was feasible and acceptable to older home care clients with depressive symptoms. It was effective in reducing depressive symptoms and improving HRQoL at six-month follow-up, with small additional improvements six months after the intervention. The intervention also reduced anxiety at one year follow-up. Significant reductions were observed in the use of hospitalization, ambulance services, and emergency room visits over the study period.

Conclusions

Our findings provide initial evidence for the feasibility, acceptability, and sustained effects of the nurse-led mental health promotion intervention in improving client outcomes, reducing use of expensive health services, and improving clinical practice behaviours of home care providers. Future research should evaluate its efficacy using a randomized clinical trial design, in different settings, with an adequate sample of older home care recipients with depressive symptoms.

There are no randomized controlled trials that support the United States Preventive Services Task Force Guideline on screening for depression in primary care: a systematic review

BACKGROUND

The United States Preventive Services Task Force (USPSTF) recommends screening adults for depression in primary care settings when staff-assisted depression management programs are available. This recommendation, however, is based on evidence from depression management programs conducted with patients already identified as depressed, even though screening is intended to identify depressed patients not already recognized or treated. The objective of this systematic review was to evaluate whether there is evidence from randomized controlled trials (RCTs) that depression screening benefits patients in primary care, using an explicit definition of screening.

METHODS

We re-evaluated RCTs included in the 2009 USPSTF evidence review on depression screening, including only trials that compared depression outcomes between screened and non-screened patients and met the following three criteria: determined patient eligibility and randomized prior to screening; excluded patients already diagnosed with a recent episode of depression or already being treated for depression; and provided the same level of depression treatment services to patients identified as depressed in the screening and non-screening trial arms. We also reviewed studies included in a recent Cochrane systematic review, but not the USPSTF review; conducted a focused search to update the USPSTF review; and reviewed trial registries.

RESULTS

Of the nine RCTs included in the USPSTF review, four fulfilled none of three criteria for a test of depression screening, four fulfilled one of three criteria, and one fulfilled two of three criteria. There were two additional RCTs included only in the Cochrane review, and each fulfilled one of three criteria. No eligible RCTs were found via the updated review.

CONCLUSIONS

The USPSTF recommendation to screen adults for depression in primary care settings when staff-assisted depression management programs are available is not supported by evidence from any RCTs that are directly relevant to the recommendation. The USPSTF should re-evaluate this recommendation. Please see related article: http://www.biomedcentral.com/1741-7015/12/14 REGISTRATION: PROSPERO (#CRD42013004276).

Primary care clinicians' recognition and management of depression: a model of depression care in real-world primary care practice

BACKGROUND

Depression is prevalent in primary care (PC) practices and poses a considerable public health burden in the United States. Despite nearly four decades of efforts to improve depression care quality in PC practices, a gap remains between desired treatment outcomes and the reality of how depression care is delivered.

OBJECTIVE

This article presents a real-world PC practice model of depression care, elucidating the processes and their influencing conditions.

DESIGN

Grounded theory methodology was used for the data collection and analysis to develop a depression care model. Data were collected from 70 individual interviews (60 to 70 min each), three focus group interviews (n = 24, 2 h each), two surveys per clinician, and investigators' field notes on practice environments. Interviews were audiotaped and transcribed for analysis. Surveys and field notes complemented interview data.

PARTICIPANTS

Seventy primary care clinicians from 52 PC offices in the Midwest: 28 general internists, 28 family physicians, and 14 nurse practitioners.

KEY RESULTS

A depression care model was developed that illustrates how real-world conditions infuse complexity into each step of the depression care process. Depression care in PC settings is mediated through clinicians' interactions with patients, practice, and the local community. A clinician's interactional familiarity ("familiarity capital") was a powerful facilitator for depression care. For the recognition of depression, three previously reported processes and three conditions were confirmed. For the management of depression, 13 processes and 11 conditions were identified. Empowering the patient was a parallel process to the management of depression.

CONCLUSIONS

The clinician's ability to develop and utilize interactional relationships and resources needed to recognize and treat a person with depression is key to depression care in primary care settings. The interactional context of depression care makes empowering the patient central to depression care delivery.

Collaborative chronic care models for mental health conditions: cumulative meta-analysis and metaregression to guide future research and implementation

OBJECTIVE

Prior meta-analysis indicates that collaborative chronic care models (CCMs) improve mental and physical health outcomes for individuals with mental disorders. This study aimed to investigate the stability of evidence over time and identify patient and intervention factors associated with CCM effects to facilitate implementation and sustainability of CCMs in clinical practice.

METHODS

We reviewed 53 CCM trials that analyzed depression, mental quality of life (QOL), or physical QOL outcomes. Cumulative meta-analysis and metaregression were supplemented by descriptive investigations across and within trials.

RESULTS

Most trials targeted depression in the primary care setting, and cumulative meta-analysis indicated that effect sizes favoring CCM quickly achieved significance for depression outcomes, and more recently achieved significance for mental and physical QOL. Four of 6 CCM elements (patient self-management support, clinical information systems, system redesign, and provider decision support) were common among reviewed trials, whereas 2 elements (health care organization support and linkages to community resources) were rare. No single CCM element was statistically associated with the success of the model. Similarly, metaregression did not identify specific factors associated with CCM effectiveness. Nonetheless, results within individual trials suggest that increased illness severity predicts CCM outcomes.

CONCLUSIONS

Significant CCM trials have been derived primarily from 4 original CCM elements. Nonetheless, implementing and sustaining this established model will require health care organization support. Although CCMs have typically been tested as population-based interventions, evidence supports stepped care application to more severely ill individuals. Future priorities include developing implementation strategies to support adoption and sustainability of the model in clinical settings while maximizing fit of this multicomponent framework to local contextual factors.

A pilot randomized controlled trial of cognitive behavioral therapy for perinatal depression adapted for women with low incomes

BACKGROUND

Perinatal women with identified depression in prenatal care settings have low rates of engagement and adherence with depression-specific psychotherapy. We report the feasibility and symptom outcomes of Cognitive Behavioral Therapy (CBT) modified (mCBT) to address the needs of perinatal, low-income women with Major Depressive Disorder (MDD).

METHODS

Pregnant women (n = 1421) were screened for depressive symptoms in obstetrics clinics in conjunction with prenatal care visits. A total of 59 women met diagnostic criteria for MDD; 55 women were randomly assigned to mCBT or Treatment as Usual (TAU). The mCBT intervention included an initial engagement session, outreach, specific perinatal content and interpersonal components. Measures were gathered at pre-treatment, 16 week post-randomization, and 3-month follow-up.

RESULTS

Most participants attended at least one CBT session and met study criteria for treatment adherence. Active research staff outreach promoted engagement and retention in the trial. Treatment satisfaction was rated as very good. In both observed and multiple imputation results, women who received mCBT demonstrated greater improvement in depressed mood than those in TAU at 16-week post-randomization and 3-month follow-up, Cohen's d = -0.71 (95% CI -4.93, -5.70).

CONCLUSIONS

Modified CBT offers promise as a feasible and acceptable treatment for perinatal women with low-incomes in prenatal care settings. Targeted delivery and content modifications are needed to engage populations tailored to setting and psychosocial challenges specific to the perinatal period.

Cost-effectiveness of depression case management in small practices

BACKGROUND

Case management undertaken by healthcare assistants in small primary care practices is effective in improving depression symptoms and adherence in patients with major depression.

AIMS

To evaluate the cost-effectiveness of depression case management by healthcare assistants in small primary care practices.

METHOD

Cost-effectiveness analysis on the basis of a pragmatic randomised controlled trial (2005-2008): practice-based healthcare assistants in 74 practices provided case management to 562 patients with major depression over 1 year. Our primary outcome was the incremental cost-effectiveness ratio (ICER) calculated as the ratio of differences in mean costs and mean number of quality-adjusted life-years (QALYs). Our secondary outcome was the mean depression-free days (DFDs) between the intervention and control group at 24-month follow-up. The study was registered at the International Standard Randomised Controlled Trial Number Registry: ISRCTN66386086.

RESULTS

Intervention v. control group: no significant difference in QALYs; significantly more DFDs (mean: 373 v. 311, P<0.01); no significant difference in mean direct healthcare costs (€4495 v. €3506, P = 0.16); considerably lower mean indirect costs (€5228 v. €7539, P = 0.06), resulting in lower total costs (€9723 v. €11 045, P = 0.41). The point estimate for the cost-utility ratio was €38 429 per QALY gained if only direct costs were considered, and 'dominance' of the intervention if total costs were considered. Yet, regardless of decision makers' willingness to pay per QALY, the probability of the intervention being cost-effective was never above 90%.

CONCLUSIONS

In small primary care practices, 1 year of case management did not increase the number of QALYs but it did increase the number of DFDs. The intervention was likely to be cost-effective.

Practice-based versus telemedicine-based collaborative care for depression in rural federally qualified health centers: a pragmatic randomized comparative effectiveness trial

OBJECTIVE

Practice-based collaborative care is a complex evidence-based practice that is difficult to implement in smaller primary care practices that lack on-site mental health staff. Telemedicine-based collaborative care virtually co-locates and integrates mental health providers into primary care settings. The objective of this multisite randomized pragmatic comparative effectiveness trial was to compare the outcomes of patients assigned to practice-based and telemedicine-based collaborative care.

METHOD

From 2007 to 2009, patients at federally qualified health centers serving medically underserved populations were screened for depression, and 364 patients who screened positive were enrolled and followed for 18 months. Those assigned to practice-based collaborative care received evidence-based care from an on-site primary care provider and a nurse care manager. Those assigned to telemedicine-based collaborative care received evidence-based care from an on-site primary care provider and an off-site team: a nurse care manager and a pharmacist by telephone, and a psychologist and a psychiatrist via videoconferencing. The primary clinical outcome measures were treatment response, remission, and change in depression severity.

RESULTS

Significant group main effects were observed for both response (odds ratio=7.74, 95% CI=3.94-15.20) and remission (odds ratio=12.69, 95% CI=4.81-33.46), and a significant overall group-by-time interaction effect was observed for depression severity on the Hopkins Symptom Checklist, with greater reductions in severity over time for patients in the telemedicine-based group. Improvements in outcomes appeared to be attributable to higher fidelity to the collaborative care evidence base in the telemedicine-based group.

CONCLUSIONS

Contracting with an off-site telemedicine-based collaborative care team can yield better outcomes than implementing practice-based collaborative care with locally available staff.

[Integral Care Guide for Early Detection and Diagnosis of Depressive Episodes and Recurrent Depressive Disorder in Adults. Integral Attention of Adults with a Diagnosis of Depressive Episodes and Recurrent Depressive Disorder: Part I: Risk Factors, Screening, Suicide Risk Diagnosis and Assessment in Patients with a Depression Diagnosis]

INTRODUCTION

Depression is an important cause of morbidity and disability in the world; however, it is under-diagnosed at all care levels.

OBJECTIVE

The purpose here is to present recommendations based on the evidence gathered to answer a series of clinical questions concerning risk factors, screening, suicide risk diagnosis and evaluation in patients undergoing a depressive episode and recurrent depressive disorder. Emphasis has been made upon the approach used at the primary care level so as to grant adult diagnosed patients the health care guidelines based on the best and more updated evidence available thus achieving minimum quality standards.

METHODOLOGY

A practical clinical guide was elaborated according to standards of the Methodological Guide of the Ministry of Social Protection. Recommendation from guides NICE90 and CANMAT were adopted and updated so as to answer the questions posed while de novo questions were developed.

RESULTS

Recommendations 1-22 corresponding to screening, suicide risk and depression diagnosis were presented. The corresponding degree of recommendation is included.

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.

Somatic symptoms in cancer patients trajectory over 12 months and impact on functional status and disability

PURPOSE

Cross-sectional studies have established the prevalence and functional impairment of somatic symptoms in cancer patients. The purpose of this study was to determine the trajectory and adverse consequences of such symptoms over time.

METHODS

Secondary analysis of longitudinal data from 405 cancer patients enrolled in a telecare management trial for pain and/or depression. Somatic symptom burden was measured with a 22-item scale at baseline, 1, 3, 6, and 12 months. Outcomes included the SF-12 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores, the Sheehan Disability Scale (SDS) score, and self-reported total disability days. Mixed methods repeated measures analyses were conducted to determine whether antecedent change in somatic symptom burden predicted functional status and disability.

RESULTS

Symptoms were highly prevalent at baseline, with 15 of the 22 symptoms endorsed by more than half of the patients. A rather constant cross-sectional prevalence over 12 months at the group level belied a quite different trajectory at the patient level where the median persistence, resolution, and incidence rates for 14 of the most common symptoms were 39%, 37%, and 24%, respectively. A clinically significant (i.e., five points) reduction in somatic symptom burden predicted improvement in PCS, MCS, and SDS (all P < 0.001), as well as a lower likelihood of ≥14 disability days in the past 4 weeks (odds ratio, 0.84; 95% CI, 0.74 to 0.95).

CONCLUSIONS

Somatic symptoms remain burdensome in cancer patients over 12 months and symptom improvement predicts significantly better functional status and less disability.
