Effectiveness of collaborative care for depression in Italy. A randomized controlled trial

The effects of collaborative care versus consultation liaison for anxiety disorders and depression in Denmark: two randomised controlled trials

BACKGROUND

Collaborative care (CC) and consultation liaison (CL) are two conceptual models aiming to improve mental healthcare in primary care. The effects of these models have not been compared in a Danish setting.

AIMS

To examine the effects of CC versus CL for persons with anxiety and depression in Danish general practices (trial registration: NCT03113175 and NCT03113201).

METHOD

Two randomised parallel superiority trials for anxiety disorders and depression were carried out in 2018-2019. In the CC-group, care managers collaborated with general practitioners (GPs) to provide evidence-based treatment according to structured treatment plans. They followed up and provided psychoeducation and/or cognitive-behavioural therapy. The GPs initiated pharmacological treatment if indicated, and a psychiatrist provided supervision. In the CL-group, the intervention consisted of the GP's usual treatment. However, the psychiatrist and care manager could be consulted. Primary outcomes were depression symptoms (Beck Depression Inventory-II, BDI-II) in the depression trial and anxiety symptoms (Beck Anxiety Inventory, BAI) in the anxiety trial at 6-month follow-up.

RESULTS

In total, 302 participants with anxiety disorders and 389 participants with depression were included. A significant difference in BDI-II score was found in the depression trial, with larger symptom reductions in the CC-group (CC: 12.7, 95% CI 11.4-14.0; CL: 17.5, 95% CI 16.2-18.9; Cohen's d = -0.50, P ≤ 0.001). There was a significant difference in BAI in the anxiety trial (CC: 14.9, 95% CI 13.5-16.3; CL: 17.9, 95% CI 16.5-19.3; Cohen's d = -0.34, P ≤ 0.001), with larger symptom reductions in the CC-group.

CONCLUSIONS

Collaborative care was an effective model to improve outcomes for persons with depression and anxiety disorders.

Examining the description of the concept "treatment as usual" for patients with depression, anxiety and stress-related mental disorders in primary health care research - A systematic review

BACKGROUND

In randomized controlled trials (RCTs) within medical research, applied interventions are compared to treatment-as-usual (TAU) as the control condition. The aim of the current study was to examine how the concept of TAU is described when used as control condition in RCTs evaluating treatments for depression, anxiety syndromes, and stress-related mental disorders in primary care.

METHOD

A systematic review of RCTs utilizing TAU as control group in the RCT in accordance with PRISMA standards was conducted. We used one multidisciplinary database (Scopus), one database focused on nursing (Cinahl), and one medical database (PubMed). The searches were conducted in November 2021 and May 2022.

RESULTS

The included 32 studies comprised of 7803 participants. The content of TAU was classified as follows: 1) Basic descriptions of TAU lacking a detailed account as well as reference to local or national guidelines, 2) Moderate description of TAU including reference to national or local guidelines or a detailed description 3) Advanced description of TAU including references to national guidelines and a detailed description containing five key concepts: early assessment, accessibility, psychological treatment, medication, somatic examination. 18 studies had basic, 11 moderate, and 3 advanced descriptions of TAU.

LIMITATIONS

The limitations were that only studies published in English were included.

CONCLUSIONS

The current study provides an assessment tool with three classification levels for TAU. The description of TAU is still insufficient in RCT studies conducted in primary care, which may affect the interpretation of results. In future research a detailed description of TAU is recommended.

Stepped care for the treatment of depression: a systematic review and meta-analysis

BACKGROUND

The Stepped Care Model (SCM) proposes a sequential approach in the treatment of depression, applying interventions of increasing intensity according to the level of severity of the individual.

METHODS

A systematic review was carried out until January 2020 in eight electronic databases. We included randomized (RCT) and non-randomized controlled trials comparing the SCM to usual non-sequential care.

RESULTS

Eighteen RCT with patients with confirmed or probable depression diagnosis were included. Meta-analyses yielded high heterogeneity, and subgroup analyses showed significant effects of the SCM only in studies with baseline moderately severe symptoms on average, compared to samples with mild/moderate depression. In the former subgroup, effects at 3-6 and 9-12 months were small for symptoms' reduction (g = -0.33, 95%CI: -0.55, -0.17 and -0.34, 95%CI: -0.53, -0.16) and moderate-to-strong in response and remission (Risk Ratios between 1.70-1.90). Overall, a significant benefit on quality of life was also observed (6 months: g = 0.31, 95%CI: 0.12, 0.49; 12 months: g = 0.18, 95%CI: 0.06, 0.31). More patients in the SCM groups were prescribed antidepressants at 6 months (RR = 1.31, 95%CI: 1.09, 1.57; I² = 87%).

LIMITATIONS

The search does not guarantee the identification of all the relevant literature. Most included studies show uncertain or high risk of bias.

CONCLUSIONS

The SCM seems to outperform usual care in populations with at least moderately severe symptoms on average. Results show high heterogeneity and future research should explore its sources.

The effectiveness of enhanced evidence-based care for depressive disorders: a meta-analysis of randomized controlled trials

Several care models have been developed to improve treatment for depression, all of which provide "enhanced" evidence-based care (EEC). The essential component of these approaches is Measurement-Based Care (MBC). Specifically, Collaborative Care (CC), and Algorithm-guided Treatment (AGT), and Integrated Care (IC) all use varying forms of rigorous MBC assessment, care management, and/or treatment algorithms as key instruments to optimize treatment delivery and outcomes for depression. This meta-analysis systematically examined the effectiveness of EEC versus usual care for depressive disorders based on cluster-randomized studies or randomized controlled trials (RCTs). PubMed, the Cochrane Library, and PsycInfo, EMBASE, up to January 6th, 2020 were searched for this meta-analysis. The electronic search was supplemented by a manual search. Standardized mean difference (SMD), risk ratio (RR), and their 95% confidence intervals (CIs) were calculated and analyzed. A total of 29 studies with 15,255 participants were analyzed. EEC showed better effectiveness with the pooled RR for response of 1.30 (95%CI: 1.13-1.50, I² = 81.9%, P < 0.001, 18 studies), remission of 1.35 (95%CI: 1.11-1.64, I² = 85.5%, P < 0.001, 18 studies) and symptom reduction with a pooled SMD of -0.42 (95%CI: -0.61-(-0.23), I² = 94.3%, P < 0.001, 19 studies). All-cause discontinuations were similar between EEC and usual care with the pooled RR of 1.08 (95%CI: 0.94-1.23, I² = 68.0%, P = 0.303, 27 studies). This meta-analysis supported EEC as an evidence-based framework to improve the treatment outcome of depressive disorders.Review registration: PROSPERO: CRD42020163668.

Effectiveness of collaborative care in reducing suicidal ideation: An individual participant data meta-analysis

To assess whether CC is more effective at reducing suicidal ideation in people with depression compared with usual care, and whether study and patient factors moderate treatment effects.

METHOD

We searched Medline, Embase, PubMed, PsycINFO, CINAHL, CENTRAL from inception to March 2020 for Randomised Controlled Trials (RCTs) that compared the effectiveness of CC with usual care in depressed adults, and reported changes in suicidal ideation at 4 to 6 months post-randomisation. Mixed-effects models accounted for clustering of participants within trials and heterogeneity across trials. This study is registered with PROSPERO, CRD42020201747.

RESULTS

We extracted data from 28 RCTs (11,165 patients) of 83 eligible studies. We observed a small significant clinical improvement of CC on suicidal ideation, compared with usual care (SMD, -0.11 [95%CI, -0.15 to -0.08]; I², 0·47% [95%CI 0.04% to 4.90%]). CC interventions with a recognised psychological treatment were associated with small reductions in suicidal ideation (SMD, -0.15 [95%CI -0.19 to -0.11]). CC was more effective for reducing suicidal ideation among patients aged over 65 years (SMD, - 0.18 [95%CI -0.25 to -0.11]).

CONCLUSION

Primary care based CC with an embedded psychological intervention is the most effective CC framework for reducing suicidal ideation and older patients may benefit the most.

Validation of the German version of the work and social adjustment scale in a sample of depressed patients

BACKGROUND

Depression is one of the key factors contributing to difficulties in one's ability to work, and serves as one of the major reasons why employees apply for psychotherapy and receive insurance subsidization of treatments. Hence, an increasing and growing number of studies rely on workability assessment scales as their primary outcome measure. The Work and Social Assessment Scale (WSAS) has been documented as one of the most psychometrically reliable and valid tools especially developed to assess workability and social functioning in patients with mental health problems. Yet, the application of the WSAS in Germany has been limited due to the paucity of a valid questionnaire in the German language. The objective of the present study was to translate the WSAS, as a brief and easy administrable tool into German and test its psychometric properties in a sample of adults with depression.

METHODS

Two hundred seventy-seven patients (M = 48.3 years, SD = 11.1) with mild to moderately severe depression were recruited. A multistep translation from English into the German language was performed and the factorial validity, criterion validity, convergent validity, discriminant validity, internal consistency, and floor and ceiling effects were examined.

RESULTS

The confirmatory factor analysis results confirmed the one-factor structure of the WSAS. Significant correlations with the WHODAS 2-0 questionnaire, a measure of functionality, demonstrated good convergent validity. Significant correlations with depression and quality of life demonstrated good criterion validity. The WSAS also demonstrated strong internal consistency (α = .89), and the absence of floor and ceiling effects indicated good sensitivity of the instrument.

CONCLUSIONS

The results of the present study demonstrated that the German version of the WSAS has good psychometric properties comparable to other international versions of this scale. The findings recommend a global assessment of psychosocial functioning with the sum score of the WSAS.

Clinical efficacy of a Decision Support Tool (Link-me) to guide intensity of mental health care in primary practice: a pragmatic stratified randomised controlled trial

BACKGROUND

The volume and heterogeneity of mental health problems that primary care patients present with is a substantial challenge for health systems, and both undertreatment and overtreatment are common. We developed Link-me, a patient-completed Decision Support Tool, to predict severity of depression or anxiety, identify priorities, and recommend interventions. In this study, we aimed to examine if Link-me reduces psychological distress among individuals predicted to have minimal/mild or severe symptoms of anxiety or depression.

METHODS

In this pragmatic stratified randomised controlled trial, adults aged 18-75 years reporting depressive or anxiety symptoms or use of mental health medication were recruited from 23 general practices in Australia. Participants completed the Decision Support Tool and were classified into three prognostic groups (minimal/mild, moderate, severe), and those in the minimal/mild and severe groups were eligible for inclusion. Participants were individually and randomly assigned (1:1) by a computer-generated allocation sequence to receive either prognosis-matched care (intervention group) or usual care plus attention control (control group). Participants were not blinded but intervention providers were only notified of those allocated to the intervention group. Outcome assessment was blinded. The primary outcome was the difference in the change in scores between the intervention and control group, and within prognostic groups, on the 10-item Kessler Psychological Distress Scale at 6 months post randomisation. The trial was registered on the Australian and New Zealand Clinical Trials Registry, ACTRN12617001333303.

OUTCOMES

Between Nov 21, 2017, and Oct 31, 2018, 24 616 patients were invited to complete the eligibility screening survey. 1671 of these patients were included and randomly assigned to either the intervention group (n=834) or the control group (n=837). Prognosis-matched care was associated with greater reductions in psychological distress than usual care plus attention control at 6 months (p=0·03), with a standardised mean difference (SMD) of -0·09 (95% CI -0·17 to -0·01). This reduction was also seen in the severe prognostic group (p=0·003), with a SMD of -0·26 (-0·43 to -0·09), but not in the minimal/mild group (p=0·73), with a SMD of 0·04 (-0·17 to 0·24). In the complier average causal effect analysis in the severe prognostic group, differences were larger among those who received some or all aspects of the intervention (SMD range -0·58 to -1·15). No serious adverse effects were recorded.

INTERPRETATION

Prognosis-based matching of interventions reduces psychological distress in patients with anxiety or depressive symptoms, particularly in those with severe symptoms, and is associated with better outcomes when patients access the recommended treatment. Optimisation of the Link-me approach and implementation into routine practice could help reduce the burden of disease associated with common mental health conditions such as anxiety and depression.

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.

Association between subthreshold depression and self-care behaviours in adults with type 2 diabetes: A protocol for a cross-sectional study

AIMS AND OBJECTIVES

To examine the association between subthreshold depression and self-care behaviours in adults with type 2 diabetes (T2D) attending a tertiary healthcare service.

BACKGROUND

Diabetes is a global public health problem. Self-care behaviours are a fundamental element in managing diabetes as adherence to self-care activities is associated with improved glycaemic control. Depression in T2D is associated with decreased adherence to self-care behaviours. Adults with subthreshold depression in diabetes may have difficulties in achieving metabolic control. Further, people with subthreshold depression have an increased risk of developing major depression. Few studies have examined the association between subthreshold depression and self-care behaviours.

DESIGN

A cross-sectional study.

METHODS

The study will be conducted among 384 adults diagnosed with T2D for at least a year attending their routine outpatient appointment at Tribhuvan University Teaching Hospital in Nepal. Convenience sampling will be used to recruit study participants. Data will be collected via face-to-face interviews and a medical record review. Self-care behaviours will be assessed using the Summary of Diabetes Self-care activities and subthreshold depression will be determined using the Patient Health Questionnaire- 9. Covariates in the study include sociodemographic and clinical factors, diabetes knowledge, perceived social support and self-efficacy. This paper complies with the STROBE reporting guideline for cross-sectional studies.

RESULTS

We will use multiple linear regression to examine the association between subthreshold depression and each self-care behaviours (i.e. diet, physical activity, foot care, blood glucose testing and medication) and total self-care behaviour.

CONCLUSIONS

Effective management of diabetes requires adherence to self-care behaviours. The findings of the study will help in identifying an effective way to improve diabetes self-care.

RELEVANCE TO CLINICAL PRACTICE

Our observations will inform nursing research and practice by providing evidence about how subthreshold depression may influence self-care behaviours.

The role of relapse prevention for depression in collaborative care: A systematic review

BACKGROUND

Relapse (the re-emergence of depression symptoms before full recovery) is common in depression and relapse prevention strategies are not well researched in primary care settings. Collaborative care is effective for treating acute phase depression but little is known about the use of relapse prevention strategies in collaborative care. We undertook a systematic review to identify and characterise relapse prevention strategies in the context of collaborative care.

METHODS

We searched for Randomised Controlled Trials (RCTs) of collaborative care for depression. In addition to published material, we obtained provider and patient manuals from authors to provide more detail on intervention content. We reported the extent to which collaborative care interventions addressed four relapse prevention components.

RESULTS

93 RCTs were identified. 31 included a formal relapse prevention plan; 42 had proactive monitoring and follow-up after the acute phase; 39 reported strategies for optimising sustained medication adherence; and 20 of the trials reported psychological or psycho-educational treatments persisting beyond the acute phase or focussing on long-term health/relapse prevention. 30 (32.3%) did not report relapse prevention approaches.

LIMITATIONS

We did not receive trial materials for approximately half of the trials, which limited our ability to identify relevant features of intervention content.

CONCLUSION

Relapse is a significant risk amongst people treated for depression and interventions are needed that specifically address and minimise this risk. Given the advantages of collaborative care as a delivery system for depression care, there is scope for more consistency and increased effort to implement and evaluate relapse prevention strategies.

Prevalence and Determinants of Long-Term Utilization of Antidepressant Drugs: A Retrospective Cohort Study

PURPOSE

Antidepressant consumption has risen in recent years, driven by longer treatment duration. The objective of this study was to measure the prevalence of antidepressant long-term and chronic use in the Bologna area, Italy, and to identify their main determinants.

MATERIALS AND METHODS

We conducted a retrospective claims-based cohort study by using the Bologna Local Health Authority data. A cohort of 18,307 incident users of antidepressant drugs in 2013 was selected, and subjects were followed for three years. A long-term utilization was defined as having at least one prescription claimed during each year of follow-up, while chronic utilization was defined as claiming at least 180 defined daily doses per year. Factors associated with chronic and long-term use were identified by univariate and multivariate logistic regressions.

RESULTS

In our cohort, 5448 (29.8%) and 1817 (9.9%) subjects were dispensed antidepressants for a long-term course and in a chronically way, respectively. Older age, antidepressant polytherapy, polypharmacy, and being prescribed the first antidepressant by a hospital physician were all factors independently associated with chronic and long-term prescriptions of antidepressant drugs. Results were reported separately for men and women.

CONCLUSION

Antidepressant long-term and chronic prescriptions are common in the Bologna area. Because longer treatment should be clinically motivated, these results strongly prompt the need to evaluate the actual relevance, as they may indicate potentially inappropriate prescription patterns.

Cost-effectiveness analysis of a randomized study of depression treatment options in primary care suggests stepped-care treatment may have economic benefits

BACKGROUND

The stepped-care pathway (SCP) model has previously been found to be clinically effective for depressive disorder in some studies, but not all. Several groups have suggested that a stepped-care approach is the most appropriate in primary care. There is relatively little information, however, regarding which specific stepped-care pathway may be best. This analysis aimed to determine cost-effectiveness of a stepped-care pathway for depression in adults in primary care versus standard care (SC), treatment-as-usual (TAU), and online cognitive behavioural therapy (CBT).

METHODS

We conducted a randomized trial with 1400 participants and 12-week follow-up to assess the impact of the four treatment options on health-related quality of life and depression severity. Costs for the groups were calculated on the basis of physician, outpatient, and inpatient services using administrative data. We then calculated the incremental cost-effectiveness ratios using this information. Cost-effectiveness acceptability curves and incremental cost-effectiveness scatterplots were created using Monte Carlo simulation with 10,000 replications. A subgroup analysis was conducted for participants who screened as depressed at baseline.

RESULTS

For all participants, TAU was the most expensive followed by CBT, SC, and SCP. QALYs were highest in SCP, followed by SC, CBT, and TAU. In the depressed subgroup, TAU was still the most expensive, followed by SC, SCP, and CBT, while QALYs were still highest in SCP, followed by SC, CBT, and TAU. The cost-effectiveness acceptability curves suggested that SCP had a higher probability for cost-effectiveness than the other three alternatives in all participants. In the depressed subgroup, CBT was associated with the highest probability of cost-effectiveness for a willingness-to-pay cut-off of less than approximately $50,000, while SCP was the highest at a cut-off higher than $50,000. There is considerable uncertainty around the cost-effectiveness estimates.

CONCLUSIONS

Our analysis showed that even where there are no clinically significant differences in health outcomes between treatment approaches, there may be economic benefit from implementing the stepped-care model. While more work is required to identify the most clinically effective versions of a stepped-care pathway, our findings suggest that the care pathway may have potential to improve health care system value.

Management of comorbid mental and somatic disorders in stepped care approaches in primary care: a systematic review

BACKGROUND

Stepped care models comprise a graded treatment intensity and a systematic monitoring. For an effective implementation, stepped care models have to account for the high rates of mental and somatic comorbidity in primary care.

OBJECTIVES

The aim of the systematic review was to take stock of whether present stepped care models take comorbidities into consideration. A further aim was to give an overview on treatment components and involved health care professionals.

METHODS

A systematic literature search was performed using the databases PubMed, PsycINFO, Cochrane Library and Web of Science. Selection criteria were a randomized controlled trial of a primary-care-based stepped care intervention, adult samples, publication between 2000 and 2017 and English or German language.

RESULTS

Of 1009 search results, 39 studies were eligible. One-third of the trials were conceived for depressive disorders only, one-third for depression and further somatic and/or mental comorbidity and one-third for conditions other than depression. In 39% of the studies comorbidities were explicitly integrated in treatment, mainly via transdiagnostic self-management support, interprofessional collaboration and digital approaches for treatment, monitoring and communication. Most care teams were composed of a primary care physician, a care manager and a psychiatrist and/or psychologist. Due to the heterogeneity of the addressed disorders, no meta-analysis was performed.

CONCLUSIONS

Several stepped care models in primary care already account for comorbidities, with depression being the predominant target disorder. To determine their efficacy, the identified strategies to account for comorbidities should be investigated within stepped care models for a broader range of disorders.

Collaborative care for the detection and management of depression among adults with hypertension in South Africa: study protocol for the PRIME-SA randomised controlled trial

Background

The high co-morbidity of mental disorders, particularly depression, with non-communicable diseases (NCDs) such as cardiovascular disease (CVD), is concerning given the rising burden of NCDs globally, and the role depression plays in confounding prevention and treatment of NCDs. The objective of this randomised control trial (RCT) is to determine the real-world effectiveness of strengthened depression identification and management on depression outcomes in hypertensive patients attending primary health care (PHC) facilities in South Africa (SA).

Methods/design

The study design is a pragmatic, two-arm, parallel-cluster RCT, the unit of randomisation being the clinics, with outcomes being measured for individual participants. The 20 largest eligible clinics from one district in the North West Province are enrolled in the trial. Equal numbers of hypertensive patients (n = 50) identified as having depression using the Patient Health Questionnaire (PHQ-9) are enrolled from each clinic, making up a total of 1000 participants with 500 in each arm. The nurse clinicians in the control facilities receive the standard training in Primary Care 101 (PC101), a clinical decision support tool for integrated chronic care that includes guidelines for hypertension and depression care. Referral pathways available include referrals to PHC physicians, clinical or counselling psychologists and outpatient psychiatric and psychological services. In the intervention clinics, this training is supplemented with strengthened training in the depression components of PC101 as well as training in clinical communication skills for nurse-led chronic care. Referral pathways are strengthened through the introduction of a facility-based behavioural health counsellor, trained to provide structured manualised counselling for depression and adherence counselling for all chronic conditions. The primary outcome is defined as at least 50% reduction in PHQ-9 score measured at 6 months.

Discussion

This trial should provide evidence of the real world effectiveness of strengtheneddepression identification and collaborative management on health outcomes of hypertensive patients withcomorbid depression attending PHC facilities in South Africa.

Collaborative care for the detection and management of depression among adults receiving antiretroviral therapy in South Africa: study protocol for the CobALT randomised controlled trial

Background

The scale-up of antiretroviral treatment (ART) programmes has seen HIV/AIDS transition to a chronic condition characterised by high rates of comorbidity with tuberculosis, non-communicable diseases (NCDs) and mental health disorders. Depression is one such disorder that is associated with higher rates of non-adherence, progression to AIDS and greater mortality. Detection and treatment of comorbid depression is critical to achieve viral load suppression in more than 90% of those on ART and is in line with the recent 90-90-90 Joint United Nations Programme on HIV/AIDS (UNAIDS) targets. The CobALT trial aims to provide evidence on the effectiveness and cost-effectiveness of scalable interventions to reduce the treatment gap posed by the growing burden of depression among adults on lifelong ART.

Methods

The study design is a pragmatic, parallel group, stratified, cluster randomised trial in 40 clinics across two rural districts of the North West Province of South Africa. The unit of randomisation is the clinic, with outcomes measured among 2000 patients on ART who screen positive for depression using the Patient Health Questionnaire (PHQ-9). Control group clinics are implementing the South African Department of Health’s Integrated Clinical Services Management model, which aims to reduce fragmentation of care in the context of rising multimorbidity, and which includes training in the Primary Care 101 (PC101) guide covering communicable diseases, NCDs, women’s health and mental disorders. In intervention clinics, we supplemented this with training specifically in the mental health components of PC101 and clinical communications skills training to support nurse-led chronic care. We strengthened the referral pathways through the introduction of a clinic-based behavioural health counsellor equipped to provide manualised depression counselling (eight sessions, individual or group), as well as adherence counselling sessions (one session, individual). The co-primary patient outcomes are a reduction in PHQ-9 scores of at least 50% from baseline and viral load suppression rates measured at 6 and 12 months, respectively.

Discussion

The trial will provide real-world effectiveness of case detection and collaborative care for depression including facility-based counselling on the mental and physical outcomes for people on lifelong ART in resource-constrained settings.

Task shifting interpersonal counseling for depression: a pragmatic randomized controlled trial in primary care

BACKGROUND

Task shifting approaches (rational redistribution of tasks among health workforce teams) to train lay professionals to assist with integrating mental health treatment in primary care has been recommended to close the mental health treatment gap for depression in low- and middle-income countries. This study aims to examine the a new model for depression care in a low-resource environment compared to enhanced treatment at usual (E-TAU).

METHODS

We trained non-specialist community health workers (local lay employees of the public health system) to provide Interpersonal Counseling (IPC) to treat depressive symptoms in the Brazilian, São Paulo city, family health strategy (FHS). We conducted a randomized controlled trial involving 86 patients with a current major depressive disorder or dysthymia (based on DSM-IV) recruited from an FHS clinic. Participants were randomized to IPC intervention (n = 43) or E-TAU (n = 43). Participants allocated to IPC received 3-4 sessions provided by community health workers; research psychologists followed the E-TAU participants to facilitate their referral to specialized mental health care within the public system. Reduction of depressive symptoms was assessed using the Hamilton Rating Scale (HDRS-17) and the Patient Health Questionnaire (PHQ-9); minor psychiatric symptomatology (including depression, anxiety and somatoform symptoms) were measured using the Self Reporting Questionnaire (SRQ); and functioning was measured by the Clinical Global Impression Scale over a 2-month period.

RESULTS

Intention-to-treat analysis showed significant improvement on symptoms for both groups over 2 months, without significant differences between them. Per-protocol analysis showed significant better HDRS-17 outcomes for the IPC group.

CONCLUSIONS

Training non-specialist community health workers in low- and middle-income countries to provide IPC could be a successful strategy in reducing the burden of depression and also potentially a low-cost and effective alternative to specialist-led services that might not be possible in low income settings.

Shared care across the interface between primary and specialty care in management of long term conditions

BACKGROUND

Shared care has been used in the management of many chronic conditions with the assumption that it delivers better care than primary or specialty care alone; however, little is known about the effectiveness of shared care.

OBJECTIVES

To determine the effectiveness of shared care health service interventions designed to improve the management of chronic disease across the primary/specialty care interface. This is an update of a previously published review.Secondary questions include the following:1. Which shared care interventions or portions of shared care interventions are most effective?2. What do the most effective systems have in common?

We searched MEDLINE, Embase and the Cochrane Library to 12 October 2015.

SELECTION CRITERIA

One review author performed the initial abstract screen; then two review authors independently screened and selected studies for inclusion. We considered randomised controlled trials (RCTs), non-randomised controlled trials (NRCTs), controlled before-after studies (CBAs) and interrupted time series analyses (ITS) evaluating the effectiveness of shared care interventions for people with chronic conditions in primary care and community settings. The intervention was compared with usual care in that setting.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data from the included studies, evaluated study quality and judged the certainty of the evidence using the GRADE approach. We conducted a meta-analysis of results when possible and carried out a narrative synthesis of the remainder of the results. We presented the results in a 'Summary of findings' table, using a tabular format to show effect sizes for all outcome types.

MAIN RESULTS

We identified 42 studies of shared care interventions for chronic disease management (N = 18,859), 39 of which were RCTs, two CBAs and one an NRCT. Of these 42 studies, 41 examined complex multi-faceted interventions and lasted from six to 24 months. Overall, our confidence in results regarding the effectiveness of interventions ranged from moderate to high certainty. Results showed probably few or no differences in clinical outcomes overall with a tendency towards improved blood pressure management in the small number of studies on shared care for hypertension, chronic kidney disease and stroke (mean difference (MD) 3.47, 95% confidence interval (CI) 1.68 to 5.25)(based on moderate-certainty evidence). Mental health outcomes improved, particularly in response to depression treatment (risk ratio (RR) 1.40, 95% confidence interval (CI) 1.22 to 1.62; six studies, N = 1708) and recovery from depression (RR 2.59, 95% CI 1.57 to 4.26; 10 studies, N = 4482) in studies examining the 'stepped care' design of shared care interventions (based on high-certainty evidence). Investigators noted modest effects on mean depression scores (standardised mean difference (SMD) -0.29, 95% CI -0.37 to -0.20; six studies, N = 3250). Differences in patient-reported outcome measures (PROMs), processes of care and participation and default rates in shared care services were probably limited (based on moderate-certainty evidence). Studies probably showed little or no difference in hospital admissions, service utilisation and patient health behaviours (with evidence of moderate certainty).

AUTHORS' CONCLUSIONS

This review suggests that shared care improves depression outcomes and probably has mixed or limited effects on other outcomes. Methodological shortcomings, particularly inadequate length of follow-up, may account in part for these limited effects. Review findings support the growing evidence base for shared care in the management of depression, particularly stepped care models of shared care. Shared care interventions for other conditions should be developed within research settings, with account taken of the complexity of such interventions and awareness of the need to carry out longer studies to test effectiveness and sustainability over time.

Dignity and Psychosocial-Related Variables in Advanced and Nonadvanced Cancer Patients by Using the Patient Dignity Inventory-Italian Version

CONTEXT

The Patient Dignity Inventory (PDI) is a valid and reliable instrument to measure dignity, as a state of physical, mental, social, and spiritual well-being in palliative care patients and an essential dimension for a comprehensive patient-centered approach.

OBJECTIVES

We examined the factor structure and correlation of the Italian version of the PDI (PDI-IT) with psychosocial variables among advanced and nonadvanced cancer outpatients in two Italian centers.

METHODS

In a sample of 194 patients, principal component analysis, reliability analysis (Cronbach's coefficient alpha), and correlation analysis of the PDI-IT were performed. Concurrent validity was evaluated with respect to the Italian versions of Patient Health Questionnaire-9 (PHQ-9), as a measure of depression, the Mini-Mental Adjustment to Cancer-Hopelessness Scale, as a measure of dysfunctional coping, and the Demoralization Scale (DS-IT), as a measure of demoralization.

RESULTS

Three factors were extracted by exploratory factor analysis, which accounted for 64.38% of the variance, namely existential distress (Cronbach's α = 0.95), psychological distress (Cronbach's α = 0.88), and physical distress (Cronbach's α = 0.81), with a Cronbach's α coefficient for the PDI-IT total score of 0.96. PDI-IT factors were significantly intercorrelated and shared between 42% and 53% of the variance. Higher scores on all the PDI-IT factors and PDI-IT total were found among patients who were clinically depressed (PHQ-9) and among those who were demoralized on the DS-IT. Significant correlations were also found between all PDI-IT and the DS-IT, PHQ-9, and the Mini-Mental Adjustment to Cancer-Hopelessness Scale.

CONCLUSIONS

The study confirmed that the PDI-IT is a valid instrument to be applied in oncology and measuring three factors, namely existential, psychological, and physical distress, as core dimensions of dignity, to be monitored and treated in clinical settings.

Depression Outcomes in Adults Attending Family Practice Were Not Improved by Screening, Stepped-Care, or Online CBT during a 12-Week Study when Compared to Controls in a Randomized Trial

There is uncertainty regarding possible benefits of screening for depression in family practice, as well as the most effective treatment approach when depression is identified. Here, we examined whether screening patients for depression in primary care, and then treating them with different modalities, was better than treatment-as-usual (TAU) alone. Screening was carried out for depression using the 9-item Patient Health Questionnaire (PHQ-9), with a score of ≥10 indicating significant depressive symptoms. PHQ-9 scores were given to family physicians prior to patients being seen (except for the Control group). Patients (n = 1,489) were randomized to one of four groups. Group #1 were controls (n = 432) in which PHQ-9 was administered, but results were not shared. Group #2 was screening followed by TAU (n = 426). Group #3 was screening followed by both TAU and the opportunity to use an online cognitive behavioral therapy (CBT) treatment program (n = 440). Group #4 utilized an evidence-based Stepped-care pathway for depression (n = 191, note that this was not available at all clinics). Of the study sample 889 (60%) completed a second PHQ-9 rating at 12 weeks. There were no statistically significant differences in baseline PHQ-9 scores between these groups. Compared to baseline, mean PHQ-9 scores decreased significantly in the depressed patients over 12 weeks, but there were no statistically significant differences between any groups at 12 weeks. Thus, for those who were depressed at baseline Control group (Group #1) scores decreased from 15.3 ± 4.2 to 4.0 ± 2.6 (p < 0.001), Screening group (Group #2) scores decreased from 15.5 ± 3.9 to 4.6 ± 3.0 (p < 0.001), Online CBT group (Group #3) scores decreased from 15.4 ± 3.8 to 3.4 ± 2.7 (p < 0.01), and the Stepped-care pathway group (Group #4) scores decreased from 15.3 ± 3.6 to 5.4 ± 2.8 (p < 0.05). In conclusion, these findings from this controlled randomized study do not suggest that using depression screening tools in family practice improves outcomes. They also suggest that much of the depression seen in primary care spontaneously resolves and do not support suggestions that more complex treatment programs or pathways improve depression outcomes in primary care. Replication studies are required due to study limitations.

Collaborative care regarding major depressed patients: A review of guidelines and current practices

Major Depressive Disorder (MDD) is a severe and common mental disorder. A growing body of evidence suggests that stepped and/or collaborative care treatment models have several advantages for severely depressed patients and caretakers. However, despite the availability of these treatment strategies and guidance initiatives, many depressive patients are solely treated by the general practitioner (GP), and collaborative care is not common. In this paper, we review a selected set of international guidelines to inventory the best strategies for GPs and secondary mental health care providers to collaborate when treating depressed patients. Additionally, we systematically searched the literature, listing potential ways of cooperation, and potentially supporting tools. We conclude that the prevailing guidelines only include few and rather vague directions regarding the cooperation between GPs and specialised mental health practitioners. Inspiring recent studies, however, suggest that relatively little efforts may result in effective collaborative care and a broader implementation of the guidelines in general.

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.

Consultation liaison in primary care for people with mental disorders

BACKGROUND

Approximately 25% of people will be affected by a mental disorder at some stage in their life. Despite the prevalence and negative impacts of mental disorders, many people are not diagnosed or do not receive adequate treatment. Therefore primary health care has been identified as essential to improving the delivery of mental health care. Consultation liaison is a model of mental health care where the primary care provider maintains the central role in the delivery of mental health care with a mental health specialist providing consultative support. Consultation liaison has the potential to enhance the delivery of mental health care in the primary care setting and in turn improve outcomes for people with a mental disorder.

OBJECTIVES

To identify whether consultation liaison can have beneficial effects for people with a mental disorder by improving the ability of primary care providers to provide mental health care.

SEARCH METHODS

We searched the EPOC Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), and bibliographic databases: MEDLINE, EMBASE, CINAHL and PsycINFO, in March 2014. We also searched reference lists of relevant studies and reviews to identify any potentially relevant studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) which compared consultation liaison to standard care or other service models of mental health care in the primary setting. Included participants were people attending primary care practices who required mental health care or had a mental disorder, and primary care providers who had direct contact with people in need of mental health care.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the titles and abstracts of identified studies against the inclusion criteria and extracted details including the study design, participants and setting, intervention, outcomes and any risk of bias. We resolved any disagreements by discussion or referral to a third author. We contacted trial authors to obtain any missing information.We collected and analysed data for all follow-up periods: up to and including three months following the start of treatment; between three and 12 months; and more than 12 months following the start of therapy.We used a random-effects model to calculate the risk difference (RD) for binary data and number needed to treat for an additional beneficial outcome (NNTB), if differences between groups were significant. The mean difference (MD) or standardised mean difference (SMD) was calculated for continuous data.

MAIN RESULTS

There were 8203 citations identified from database searches and reference lists. We included 12 trials with 2605 consumer participants and more than 905 primary care practitioner participants. Eleven trials compared consultation liaison to standard care and one compared consultation liaison to collaborative care, with a case manager co-ordinating mental health care. People with depression were included in eight trials; and one trial each included people with a variety of disorders: depression, anxiety and somatoform disorders; medically unexplained symptoms; and drinking problems. None of the included trials reported separate data for children or older people.There was some evidence that consultation liaison improved mental health up to three months following the start of treatment (two trials, n = 445, NNTB 8, 95% CI 5 to 25) but there was no evidence of its effectiveness between three and 12 months. Consultation liaison also appeared to improve consumer satisfaction (up to three months: one trial, n = 228, NNTB 3, 95% CI 3 to 5; 3 to 12 months: two trials, n = 445, NNTB 8, 95% CI 5 to 17) and adherence (3 to 12 months: seven trials, n = 1251, NNTB 6, 95% CI 4 to 13) up to 12 months. There was also an improvement in the primary care provider outcomes of providing adequate treatment between three to 12 months (three trials, n = 797, NNTB 7, 95% CI 4 to 17) and prescribing pharmacological treatment up to 12 months (four trials, n = 796, NNTB 13, 95% CI 7 to 50). There was also some evidence that consultation liaison may not be as effective as collaborative care in regards to symptoms of mental disorder, disability, general health status, and provision of treatment.The quality of these findings were low for all outcomes however, apart from consumer adherence from three to 12 months, which was of moderate quality. Eight trials were rated a high risk of performance bias because consumer participants were likely to have known whether or not they were allocated to the intervention group and most outcomes were self reported. Bias due to attrition was rated high in eight trials and reporting bias was rated high in six.

AUTHORS' CONCLUSIONS

There is evidence that consultation liaison improves mental health for up to three months; and satisfaction and adherence for up to 12 months in people with mental disorders, particularly those who are depressed. Primary care providers were also more likely to provide adequate treatment and prescribe pharmacological therapy for up to 12 months. There was also some evidence that consultation liaison may not be as effective as collaborative care in terms of mental disorder symptoms, disability, general health status, and provision of treatment. However, the overall quality of trials was low particularly in regards to performance and attrition bias and may have resulted in an overestimation of effectiveness. More evidence is needed to determine the effectiveness of consultation liaison for people with mental disorders particularly for those with mental disorders other than depression.

The effectiveness of toolkits as knowledge translation strategies for integrating evidence into clinical care: a systematic review

OBJECTIVES

The aim of this systematic review was to evaluate the effectiveness of toolkits as a knowledge translation (KT) strategy for facilitating the implementation of evidence into clinical care. Toolkits include multiple resources for educating and/or facilitating behaviour change.

DESIGN

Systematic review of the literature on toolkits.

METHODS

A search was conducted on MEDLINE, EMBASE, PsycINFO and CINAHL. Studies were included if they evaluated the effectiveness of a toolkit to support the integration of evidence into clinical care, and if the KT goal(s) of the study were to inform, share knowledge, build awareness, change practice, change behaviour, and/or clinical outcomes in healthcare settings, inform policy, or to commercialise an innovation. Screening of studies, assessment of methodological quality and data extraction for the included studies were conducted by at least two reviewers.

RESULTS

39 relevant studies were included for full review; 8 were rated as moderate to strong methodologically with clinical outcomes that could be somewhat attributed to the toolkit. Three of the eight studies evaluated the toolkit as a single KT intervention, while five embedded the toolkit into a multistrategy intervention. Six of the eight toolkits were partially or mostly effective in changing clinical outcomes and six studies reported on implementation outcomes. The types of resources embedded within toolkits varied but included predominantly educational materials.

CONCLUSIONS

Future toolkits should be informed by high-quality evidence and theory, and should be evaluated using rigorous study designs to explain the factors underlying their effectiveness and successful implementation.

Managing depression in people with multimorbidity: a qualitative evaluation of an integrated collaborative care model

BACKGROUND

Patients with comorbid depression and physical health problems have poorer outcomes compared with those with single long term conditions (LTCs), or multiple LTCs without depression. Primary care has traditionally struggled to provide integrated care for this group. Collaborative care can reduce depression in people with LTCs but evidence is largely based on trials conducted in the United States that adopted separate treat to target protocols for physical and mental health. Little is known about whether collaborative care that integrates depression care within the management of LTCs is implementable in UK primary care, and acceptable to patients and health care professionals.

METHODS

Nested interview study within the COINCIDE trial of collaborative care for patients with depression and diabetes/CHD (ISRCTN80309252). The study was conducted in primary care practices in North West England. Professionals delivering the interventions (nurses, GPs and psychological well-being practitioners) and patients in the intervention arm were invited to participate in semi-structured qualitative interviews.

RESULTS

Based on combined thematic analysis of 59 transcripts, we identified two major themes: 1) Integration: patients and professionals valued collaborative ways of working because it enhanced co-ordination of mental and physical health care and provided a sense that patients' health was being more holistically managed. 2) Division: patients and professionals articulated a preference for therapeutic and spatial separation between mental and physical health. Patients especially valued a separate space outside of their LTC clinic to discuss their emotional health problems.

CONCLUSION

The COINCIDE care model, that sought to integrate depression care within the context of LTC management, achieved service level integration but not therapeutic integration. Patients preferred a protected space to discuss mental health issues, and professionals maintained barriers around physical and mental health expertise. Findings therefore suggest that in the context of mental-physical multimorbidity, collaborative care can facilitate access to depression care in ways that overcome stigma and enhance the confidence of multidisciplinary health teams to work together. However, such care models need to be flexible and patient centred to accommodate the needs of patients for whom their depression may be independent of their LTC.

Collaborative care for depression in European countries: a systematic review and meta-analysis

OBJECTIVES

This is a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating the effectiveness of collaborative care compared to Primary Care Physician's (PCP's) usual care in the treatment of depression, focusing on European countries.

METHODS

A systematic review of English and non-English articles, from inception to March 2014, was performed using database PubMed, British Nursing Index and Archive, Ovid Medline (R), PsychINFO, Books@Ovid, PsycARTICLES Full Text, EMBASE Classic+Embase, DARE (Database of Abstract of Reviews of Effectiveness) and the Cochrane Library electronic database. Search term included depression, collaborative care, physician family and allied health professional. RCTs comparing collaborative care to usual care for depression in primary care were included. Titles and abstracts were independently examined by two reviewers, who extracted from the included trials information on participants' characteristics, type of intervention, features of collaborative care and type of outcome measure.

RESULTS

The 17 papers included, regarding 15 RCTs, involved 3240 participants. Primary analyses showed that collaborative care models were associated with greater improvement in depression outcomes in the short term, within 3 months (standardized mean difference (SMD) -0.19, 95% CI=-0.33; -0.05; p=0.006), medium term, between 4 and 11 months (SMD -0.24, 95% CI=-0.39; -0.09; p=0.001) and medium-long term, from 12 months and over (SMD -0.21, 95% CI=-0.37; -0.04; p=0.01), compared to usual care.

CONCLUSIONS

The present review, specifically focusing on European countries, shows that collaborative care is more effective than treatment as usual in improving depression outcomes.
