Depression in primary care: part 2-management

Depression care trajectories and associations with subsequent depressive episode: a registry-based cohort study (The Norwegian GP-DEP study)

BACKGROUND

Depression often has a recurrent course, but knowledge about the impact of treatment trajectories is scarce. We aimed to estimate treatment trajectories for patients with recurrent depression, and to explore associations between the trajectories and subsequent depressive episodes.

METHODS

Cohort study based on linked registry data, comprising all Norwegian residents ≥ 18 years with an (index) depressive episode in 2012 following previous episode(s) in 2008-2011. We generated multi-trajectories based on treatment during index episode including GP follow-up consultation(s), long consultation(s) and/or talking therapy (with GP), antidepressants, and contact(s) with specialist care. Generalized linear models were used to analyse associations between different treatment trajectories and subsequent depression within one year.

RESULTS

The study population consisted of 9 027 patients, mean age 44.6 years, 63.9% women. Five treatment trajectory groups were identified: "GP 1 month" (45.2% of the patients), "GP 6 months" (31.9%), "GP 12 months" (9.3%), "Antidepressants 12 months" (9.0%), and"Specialist 12 months" (4.6%). In group"GP 1 month" (reference), 25.1% had subsequent depression. While trajectory group "Antidepressants 12 months", had similar likelihood of subsequent depression as the reference (Relative risk (RR) = 1.04, 95% confidence interval (CI) 0.91-1.18), the groups "GP 12 months" (RR = 1.43, CI 1.28-1.59), "Specialist 12 months" (RR = 1.26, CI 1.08-1.47) and "GP 6 months" (RR = 1.17, CI 1.07-1.26) had increased risk of subsequent depression.

CONCLUSIONS

Our findings suggest that long-term antidepressant treatment of patients with recurrent depressive episodes may prevent subsequent depression episodes. However, this finding needs to be confirmed through studies that take into account the severity of depression.

Development and validation of a Chinese general practitioners' ability to recognise and manage depression assessment scale: a cross-sectional study

OBJECTIVES

There is a shortage of reliable tools to evaluate general practitioners' (GPs) ability to recognise and manage depression. The main aim of this study was to develop and validate a reliable tool for assessing the GPs' ability to recognise and manage depression.

DESIGN

A cross-sectional survey incorporating the GPs' ability to recognise and manage the depression assessment scale, the work was administered between July 2023 and June 2024. GPs' ability to recognise and manage the depression assessment scale was developed in four phases: (1) item pool construction, (2) expert consultation, (3) exploratory factor analysis for further item reduction and to identify the factor structure of the revised scale and (4) confirmatory factor analyses to confirm the factors identified within the exploratory factor analysis.

SETTING

Primary healthcare in China.

PARTICIPANTS

A total of 421 GPs participated in the study across phases 3 and 4. Phase 3 included 172 GPs, and phase 4 involved 249 GPs. They had been working in primary healthcare, with 44.42% having more than 10 years of experience. Of the participants, 57% were female.

RESULTS

The GPs' ability to recognise and manage the depression assessment scale comprised two dimensions, with 24 items. Two factors explained 66.62% of the items' variance through exploratory factor analysis. Confirmatory factor analysis confirmed two dimensions of the scale and produced appropriate Goodness of Fit Indexes. Reliability was robust, with composite reliability coefficients exceeding 0.60, Cronbach's alpha at 0.96 and a Spearman-Brown coefficient of 0.86.

CONCLUSIONS

The newly developed scale is a reliable and valid tool for assessing GPs' abilities to recognise and manage depression. It is suitable for large-scale surveys, particularly in underdeveloped regions, and can help identify gaps in knowledge. The scale results highlight areas where GPs' skills are lacking, enabling the design of targeted continuing education programmes. It can also assess the effectiveness of depression training courses, providing a foundation for tailored interventions.

Role of primary care in depression relapse: a qualitative study

BACKGROUND

Relapse contributes to the clinical and societal burden associated with depression. It is not well understood how relapse risk and prevention are managed and discussed between patients and GPs in primary care.

AIM

To understand the extent to which relapse risk and prevention are discussed and managed in general practice.

DESIGN AND SETTING

A qualitative study undertaken in general practice in the UK.

METHOD

Participants were recruited through general practices. Data were generated using semi-structured interviews and analysed using thematic analysis. Patient and public involvement informed all aspects of the study.

RESULTS

Twenty-three people with lived experience of depression and 22 GPs were interviewed. The following three themes are presented in this paper: perceived determinants of depression course (participants viewed environmental, social, and personal factors as being most important); relapse risk and prevention (relapse was considered important but not consistently or routinely discussed in general practice consultations); and relationships and communication (participants discussed the key role of the GP-patient relationship). Conceptually, relapse was perceived as having limited meaning and usefulness in primary care, owing to the implication of an episodic, discrete course not recognised by many patients and an over-reliance on biomedical diagnosis. Longer-term follow-up and monitoring of depression could be improved in primary care.

CONCLUSION

We provide an evidence-informed framework to improve practice systems and GP consultations to enhance longer-term care and support for people with depression. Going forwards, acute depression management could be optimised to include discussions of relapse risk and prevention. Brief, scalable relapse prevention interventions are needed for use in primary care.

Modifiable protective factors for mental health resilience in the offspring of depressed parents: A high-risk longitudinal cohort spanning adolescence and adulthood

Background

Several protective factors have been identified for mental health (MH) resilience in adolescent offspring of depressed parents. However, it is unclear if these effects persist into adulthood.

Methods

Depressed parents and their offspring (N = 188) from the Early Prediction of Adolescent Depression study were assessed four times (mean offspring ages 12.39, 13.77, 14.82, and 23.41). Mental health resilience was examined using residual scores (better-than-expected mood-, behaviour-, or anxiety-related MH at mean age 23 given risk exposure), and categorically as sustained good MH across adolescence and young adulthood.

Results

Only 9.2% of young adults demonstrated sustained good MH. Parents of resilient individuals showed lower comorbidity (anxiety, antisocial behaviour and harmful drinking) and higher depression remission. Considering adolescent protective factors, weak evidence was observed of associations of mood-resilience with adolescent peer-relationship quality (β = -0.20, 95%CI:-0.36, -0.04); friendship quality (β = -0.14, 95%CI:-0.31, 0.02); risk adjustment (β = -0.16, 95%CI:-0.34, 0.03) and dysfunctional attitudes (β = 0.18, 95%CI:0.01, 0.35). There was weak evidence of behavioural-resilience association with parent positive expressed emotion (β = -0.15, 95%CI:-0.31, 0.02) and offspring exercise (β = -0.37, 95%CI:-0.77, 0.03). No adolescent protective factors showed an association with anxiety-resilience. For sustained good MH, there was weak evidence of an association with inhibitory control (OR = 0.39, 95%CI:0.14, 1.07). Strong evidence was observed for associations between young adult-reported peer relationship quality and mood-resilience (β = -0.35, 95%CI:-0.53, -0.17), behavioural-resilience (β = -0.33, 95%CI:-0.51, -0.14) and anxiety-resilience (β = -0.34, 95%CI:-0.53, -0.14), while weak evidence was observed of an association of social activities with anxiety-resilience (β = -0.51, 95%CI:-0.97, -0.06).

Conclusions

We found limited evidence for the long-lasting effects of adolescent protective factors on adult MH resilience. Social factors remained protective into young adulthood, while family factors did not. Early preventative intervention might not be sufficient to maintain good long-term MH, and young people will likely require more prolonged support.

Process of change for people with knee osteoarthritis undergoing cognitive functional therapy: a replicated single-case experimental design study

PURPOSE

To examine the applicability and process of change of Cognitive Functional Therapy (CFT) in the management of pain and disability in people with knee osteoarthritis who were offered knee replacement surgery and had risk factors for poor response to surgery.

METHODS

Single-case experimental design with a mixed-methods, repeated measures approach was used to investigate the process of change through CFT in four participants. Qualitative interviews investigated beliefs, behaviours and coping responses, and self-reported measures assessed pain, disability, psychological factors, and function at 25 timepoints. Study registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12619001491156).

RESULTS

Qualitative data indicate that CFT promoted helpful changes in all participants, with two responses observed. One reflected a clear shift to a biopsychosocial conceptualisation of osteoarthritis, behavioural re-engagement and the view that a knee replacement was no longer necessary. The other response reflected a mixed conceptualisation with dissonant beliefs about osteoarthritis and its management. Psychological and social factors were identified as potential treatment barriers. Overall, quantitative measures supported the qualitative findings.

CONCLUSION

The process of change varies between and within individuals over time. Psychological and social barriers to treatment have implications for future intervention studies for the management of knee osteoarthritis.IMPLICATIONS FOR REHABILITATIONCognitive Functional Therapy is applicable in the management of knee osteoarthritis.Reconceptualisation of osteoarthritis reflected a helpful change.Psychological and social factors emerged as barriers to recovery.

Telemental Health Use Is Associated With Lower Health Care Spending Among Medicare Beneficiaries With Major Depression

BACKGROUND

Some policymakers are concerned that expanding telehealth coverage may increase Medicare expenditures. However, there is limited evidence on the association of telehealth use with utilization and spending among Medicare beneficiaries with major depression.

OBJECTIVE

To examine the differences in spending and utilization among telemental health users and non-telemental health users with major depression.

METHODS

We examined 2014-2019 traditional Medicare claims data for beneficiaries aged ≥50 years with major depression in Texas. Multivariable generalized linear models were used to assess the relationships between telemental health use and Medicare spending and utilization while adjusting for patient demographics and programmatic and clinical factors.

RESULTS

In each of the years between 2014 and 2019, an average of 4.6% Medicare beneficiaries with major depression had at least 1 telemental health visit. Compared with beneficiaries without a telemental health visit, those who had a telemental health visit were significantly more likely to be enrolled in Medicaid, be Medicare eligible due to a disability, live in a lower income area or in a rural area, and have a higher comorbidity index. Beneficiaries utilizing telemental health services incurred higher unadjusted Medicare spending than those not receiving telemental health services. However, this difference appeared due to beneficiary and programmatic characteristics rather than telemental health use. Adjusting for model covariates, the telemental health group had lower overall per member per year predicted spending, inpatient admissions, and emergency department visits than non-telemental health users.

CONCLUSION

Our findings suggest that telemental health care use may improve access to mental health care without increasing Medicare spending among telemental health users in Texas.

Barriers and facilitators to depression care among Latino men in a primary care setting: a qualitative study

BACKGROUND

In the United States, Latinos face a wide array of cultural and structural barriers to accessing and utilizing mental health care. Latino men specifically are at high risk of receiving inadequate mental health care, possibly due to additional obstacles they experience that are related to masculinity. Among men more generally, greater adherence to emotional control and self-reliance is associated with higher depression severity and less depression help-seeking. Men experience more stigma toward depression and help-seeking and are less likely to be diagnosed with depression than women. However, Latino men's barriers and facilitators to depression care remain largely unexplored. The objective of this study was to examine barriers and facilitators to depression care that are related to masculinity among English- and Spanish-speaking Latino men in a primary care setting.

METHODS

We used convenience and purposive sampling to recruit primary care patients who self-identified as Latino men, spoke English or Spanish, and screened positive for depressive symptoms on the Patient Health Questionnaire-2 or had a history of depression. Semi-structured interviews were conducted between December 2020 and August 2021. The interview guide examined views and experiences of depression, masculinity, and barriers and facilitators to engaging in depression care. Utilizing consensual qualitative research and thematic analysis informed by modified grounded theory, barriers and facilitators to depression care were identified.

RESULTS

We interviewed thirteen participants who varied in English proficiency, education, income, and country of origin. Barriers and facilitators were placed into three domains-Self-Recognition of Depression, Seeking Help for Depression, and Depression Diagnosis and Treatment. Participants described aspects of masculinity as barriers (emotional control and pressure to provide), facilitators (honesty, courage, collaboration, practicality, and responsibility), or both (self-reliance and autonomy).

CONCLUSIONS

Masculinity influences barriers and facilitators for depression care among Latino men at the levels of self-recognition, seeking help, and diagnosis and treatment. Clinicians may promote Latino men's engagement in depression care by understanding patients' values and framing depression care as affirming masculinity. Providing education to primary care physicians and other healthcare professionals on gender and depression and addressing structural barriers are essential to providing access to all who need depression care.

Antidepressant prescribing patterns and adverse events following introduction of a National Prescribing Indicator to monitor dosulepin usage in Wales

AIMS

Limiting use of the antidepressant dosulepin has been encouraged due to associated risks of toxicity. In April 2011, the All Wales Medicines Strategy Group introduced a National Prescribing Indicator (NPI) to monitor dosulepin usage. The aim of this study was to investigate antidepressant prescribing patterns, and selected adverse events in patients prescribed dosulepin following introduction of the NPI.

METHODS

An e-cohort study was conducted. Adult patients receiving regular dosulepin prescriptions between October 2010 and March 2011 were included. Characteristics of patients who were continued on dosulepin, were switched to an alternative antidepressant or whose dosulepin was discontinued following introduction of the NPI were compared.

RESULTS

In total, 4121 patients were included. Of these, 1947 (47%) continued dosulepin, 1487 (36%) were switched and 692 (17%) discontinued. Of the 692 who discontinued, 92% did not receive a prescription for another antidepressant during the follow-up period. Patients whose dosulepin was discontinued were older and were less commonly coprescribed benzodiazepines. During follow-up, recorded incidence of selected adverse events was low across all groups and no significant difference was observed.

CONCLUSION

Over half of patients had discontinued dosulepin at the end of the period when the NPI was in place. Further interventions may have been required to have a greater impact on prescribing. This study provides some reassurance that dosulepin discontinuation can be a successful strategy, and that the risk of the adverse events investigated was unlikely to have been greater in those who had dosulepin discontinued than in those in whom dosulepin had been continued.

Disease progression to bipolar disorder among adolescents and young adults with antidepressant-resistant and antidepressant-responsive depression: Does antidepressant class matter?

Studies have demonstrated a positive relationship between antidepressant resistance and the progression of bipolar disorder. However, the influence of antidepressant classes such as selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) in this context has yet to be investigated. A total of 5,285 adolescents and young adults with antidepressant-resistant depression and 21,140 with antidepressant-responsive depression were recruited in the present study. The antidepressant-resistant depression group was divided into two subgroups: only resistant to SSRIs (n = 2,242, 42.4%) and additionally resistant to non-SSRIs (n = 3,043, 57.6%) groups. The status of bipolar disorder progression was monitored from the date of depression diagnosis to the end of 2011. Patients with antidepressant-resistant depression were more likely to develop bipolar disorder during the follow-up (hazard ratio [HR]: 2.88, 95% confidence interval [CI]: 2.67-3.09) than those with antidepressant-responsive depression. Furthermore, the group that was additionally resistant to non-SSRIs were at the highest risk of bipolar disorder (HR: 3.02, 95% CI: 2.76-3.29), followed by the group that was only resistant to SSRIs (2.70, 2.44-2.98). Adolescents and young adults with antidepressant-resistant depression, especially those who responded poorly to both SSRIs and SNRIs, were at increased risk of subsequent bipolar disorder compared with those with antidepressant-responsive depression. Further studies are warranted to elucidate the molecular pathomechanisms underlying the resistance to SSRIs and SNRIs and subsequent bipolar disorder.

Lost in translation? A qualitative study of representations and management of chronic depression in general practice

BACKGROUND

GPs are on the front line for the identification and management of chronic depression but not much is known of their representations and management of chronic depression.

OBJECTIVES

To analyze GPs' representations of chronic depression and to explore how they manage it.

METHODS

Three focus groups were conducted with 22 French-speaking general practitioners in Switzerland. The focus groups were transcribed and coded with MaxQDA. A detailed content analysis was carried out and the results were synthesized into a conceptual map.

RESULTS

GPs form representations of chronic depression at the intersection of expert and lay knowledge. When talking about patients suffering from chronic depression, GPs mention middle-aged women with complex psychosocial situations and somatic complaints. GPs' management of chronic depression relies on the relationship with their patients, but also on taking care of them as a whole: psyche, body and social context. GPs often feel helpless and lonely when confronted with a patient with chronic depression. They insist on the importance of collaboration and supervision. As regards chronic depression management, GPs remain alone with patients suffering from complex biopsychosocial situations. In other situations, GPs seek the help of a psychiatrist, sometimes quickly, sometimes after a long approach. In each situation, GPs have to develop skills for translating patients' complaints.

CONCLUSION

GPs endorse a role of interpreter, making the physical presentation of their patient complaints move towards a psychological appreciation. Our results call for a renewed interest in GPs' role as interpreters and the means to achieve it.

Improving screening for major depressive disorder

BACKGROUND

Depression affects up to 20% of primary care patients and negatively affects patients' mental and physical health.

LOCAL PROBLEM

At a primary care clinic, a review of 291 patient records revealed that no patients were being screened for depression using a validated and reliable tool.

METHODS

The problem was addressed through the implementation of a depression screening and management protocol based on the U.S. Preventive Services Task Force guidelines. Processes used were recommended by the American College of Preventive Medicine and Institute for Clinical Systems Improvement.

INTERVENTIONS

This project implemented a protocol to screen, treat, and manage patients with depression at this primary care clinic. Analysis compared preimplementation and postimplementation metrics, including the number of patients screened for depression, newly diagnosed with depression, offered antidepressants, offered referral, and managed with follow-up.

RESULTS

Implementing a depression screening and management protocol in this clinic significantly increased depression screenings, the percent of patients newly diagnosed with depression, and the number of patients offered treatment.

CONCLUSION

This quality improvement (QI) project improved screening, diagnosis, and management of patients with depression in this primary care clinic. A future QI project for this clinic should focus on measures to track improvements in patients with depression at this primary care clinic.

Predictive potential of somatic symptoms for the identification of subthreshold depression and major depressive disorder in primary care settings

BACKGROUND

The presence of heterogenous somatic symptoms frequently obscures the recognition of depression in primary care. We aimed to explore the association between somatic symptoms and subthreshold depression (SD) and Major Depressive Disorder (MDD), as well as to determine the predictive potential of somatic symptoms in identifying SD and MDD in primary care.

METHODS

Data were derived from the Depression Cohort in China study (ChiCTR registry number: 1900022145). The Patient Health Questionnaire-9 (PHQ-9) was used to assess SD by trained general practitioners (GPs), and the Mini International Neuropsychiatric Interview depression module was used to diagnose MDD by professional psychiatrists. Somatic symptoms were assessed using the 28-item Somatic Symptoms Inventory (SSI).

RESULTS

In total of 4,139 participants aged 18-64 years recruited from 34 primary health care settings were included. The prevalence of all 28 somatic symptoms increased in a dose-dependent manner from non-depressed controls to SD, and to MDD (P for trend <0.001). Hierarchical clustering analysis grouped the 28 heterogeneous somatic symptoms into three clusters (Cluster 1: energy-related symptoms, Cluster 2: vegetative symptoms, and Cluster 3: muscle, joint, and central nervous symptoms). Following adjustment for potential confounders and the other two clusters of symptoms, per 1 increase of energy-related symptoms exhibited significant association with SD (OR = 1.24, 95% CI, 1.18-1.31) and MDD (OR = 1.50, 95% CI, 1.41-1.60) The predictive performance of energy-related symptoms in identifying individuals with SD (AUC = 0.715, 95% CI, 0.697-0.732) and MDD (AUC = 0.941, 95% CI, 0.926-0.963) was superior to the performance of total SSI and the other two clusters (P < 0.05).

CONCLUSIONS

Somatic symptoms were associated with the presence of SD and MDD. In addition, somatic symptoms, notably those related to energy, showed good predictive potential in identifying SD and MDD in primary care. The clinical implication of the present study is that GPs should consider the closely related somatic symptoms for early recognition for depression in practice.

Association of domain-specific physical activity with depressive symptoms: A population-based study

BACKGROUND

It remains unclear whether all physical activity (PA) domains (e.g., occupation-related PA [OPA], transportation-related PA [TPA], and leisure-time PA [LTPA]) have equivalent beneficial relationships. We aimed to investigate the associations of OPA, TPA, and LTPA with depressive symptoms in adults.

METHODS

We included and analyzed 31,221 participants (aged ≥18 years) from the cross-sectional 2007-2018 U.S. National Health and Nutrition Examination Survey (NHANES). The PA domains were assessed by a self-report questionnaire and categorized based on the PA guidelines. Depressive symptoms were measured by the nine-item Patient Health Questionnaire.

RESULTS

Participants achieving PA guidelines (≥150 min/week) were 26% (odds ratio [OR] 0.74, 95% confidence interval [CI] 0.68-0.80) and 43% (OR 0.57, 95% CI 0.51-0.62) less likely to have depressive symptoms depending on total PA and LTPA, respectively, while OPA or TPA did not demonstrate lower risks of depressive symptoms. LTPA at levels of 1-149, 150-299, and ≥300 min/week was associated with 31% (OR 0.69, 95% CI 0.60-0.78), 43% (OR 0.57, 95% CI 0.49-0.67), and 51% (OR 0.49, 95% CI 0.43-0.55) lower odds of depressive symptoms, respectively.

CONCLUSION

LTPA, but not OPA or TPA, was associated with a lower risk of depressive symptoms at any amount, suggesting that significant mental health would benefit from increased PA, even at levels below the recommendation.

Predictors and outcomes in primary depression care (POKAL) - a research training group develops an innovative approach to collaborative care

BACKGROUND

The interdisciplinary research training group (POKAL) aims to improve care for patients with depression and multimorbidity in primary care. POKAL includes nine projects within the framework of the Chronic Care Model (CCM). In addition, POKAL will train young (mental) health professionals in research competences within primary care settings. POKAL will address specific challenges in diagnosis (reliability of diagnosis, ignoring suicidal risks), in treatment (insufficient patient involvement, highly fragmented care and inappropriate long-time anti-depressive medication) and in implementation of innovations (insufficient guideline adherence, use of irrelevant patient outcomes, ignoring relevant context factors) in primary depression care.

METHODS

In 2021 POKAL started with a first group of 16 trainees in general practice (GPs), pharmacy, psychology, public health, informatics, etc. The program is scheduled for at least 6 years, so a second group of trainees starting in 2024 will also have three years of research-time. Experienced principal investigators (PIs) supervise all trainees in their specific projects. All projects refer to the CCM and focus on the diagnostic, therapeutic, and implementation challenges.

RESULTS

The first cohort of the POKAL research training group will develop and test new depression-specific diagnostics (hermeneutical strategies, predicting models, screening for suicidal ideation), treatment (primary-care based psycho-education, modulating factors in depression monitoring, strategies of de-prescribing) and implementation in primary care (guideline implementation, use of patient-assessed data, identification of relevant context factors). Based on those results the second cohort of trainees and their PIs will run two major trials to proof innovations in primary care-based a) diagnostics and b) treatment for depression.

CONCLUSION

The research and training programme POKAL aims to provide appropriate approaches for depression diagnosis and treatment in primary care.

Implementation of Group Interpersonal Psychotherapy in primary care

OBJECTIVE

To show the implementation process of IPT-G in primary care, including facilitating and obstructing factors, implementation strategies, and training and supervision of primary care professionals.

METHODS

Quantitative (cross-sectional and longitudinal) analysis of pre and post-knowledge tests; qualitative analyses of the training courses; patient recruitment; conduction of IPT-G sessions; supervision of IPT-G therapists; application of a semi-structured questionnaire to assess, investigate, and develop strategies against the identified barriers.

RESULTS

About 120 clinicians answered the pre-test; 84 completed the post-test. Pre- and post-test scores of IPT-G knowledge were significantly different. Twenty initially trained clinicians completed additional supervision in IPT-G. Qualitative analysis identified twelve barriers and six facilitators to IPT-G implementation in individual, organizational, and systemic contexts.

CONCLUSIONS

Implementation of IPT-G in primary care is a complex process with several steps. In the first step, health professionals were successfully trained in IPT-G. However, subsequent steps were more complex. Therefore, careful planning of IPT-G implementation is essential to maximize the success of this innovation.

Effects of decision aids for depression treatment in adults: systematic review

AIM AND METHOD

To determine the effect on decisional-related and clinical outcomes of decision aids for depression treatment in adults in randomised clinical trials. In January 2019, a systematic search was conducted in five databases. Study selection and data extraction were performed in duplicate. Meta-analyses were performed, and standardised and weighted mean differences were calculated, with corresponding 95% confidence intervals. The certainty of the evidence was evaluated with GRADE methodology.

RESULTS

Six randomised clinical trials were included. The pooled estimates showed that decision aids for depression treatment had a beneficial effect on patients' decisional conflict, patient knowledge and information exchange between patient and health professional. However, no statistically significant effect was found for doctor facilitation, treatment adherence or depressive symptoms. The certainty of the evidence was very low for all outcomes.

CLINICAL IMPLICATIONS

Using decision aids to choose treatment in patients with depression may have a a beneficial effect on decisional-related outcomes, but it may not translate into an improvement in clinical outcomes.

Advances in ameliorating inflammatory diseases and cancers by andrographolide: Pharmacokinetics, pharmacodynamics, and perspective

Andrographolide, a well-known natural lactone having a range of pharmacological actions in traditional Chinese medicine. It has long been used to cure a variety of ailments. In this review, we cover the pharmacokinetics and pharmacological activity of andrographolide which supports its further clinical application in cancers and inflammatory diseases. Growing evidence shows a good therapeutic effect in inflammatory diseases, including liver diseases, joint diseases, respiratory system diseases, nervous system diseases, heart diseases, inflammatory bowel diseases, and inflammatory skin diseases. As a result, the effects of andrographolide on immune cells and the processes that underpin them are discussed. The preclinical use of andrographolide to different organs in response to malignancies such as colorectal, liver, gastric, breast, prostate, lung, and oral cancers has also been reviewed. In addition, several clinical trials of andrographolide in inflammatory diseases and cancers have been summarized. This review highlights recent advances in ameliorating inflammatory diseases as well as cancers by andrographolide and its analogs, providing a new perspective for subsequent research of this traditional natural product.

Primary care and mental health: Where do we go from here?

Primary care has been dubbed the “de facto” mental health system of the United States since the 1970s. Since then, various forms of mental health delivery models for primary care have proven effective in improving patient outcomes and satisfaction and reducing costs. Despite increases in collaborative care implementation and reimbursement, prevalence rates of major depression in the United States remain unchanged while anxiety and suicide rates continue to climb. Meanwhile, primary care task forces in countries like the United Kingdom and Canada are recommending against depression screening in primary care altogether, citing lack of trials demonstrating improved outcomes in screened vs unscreened patients when the same treatment is available, high false-positive results, and small treatment effects. In this perspective, a primary care physician and two psychiatrists address the question of why we are not making headway in treating common mental health conditions in primary care. In addition, we propose systemic changes to improve the dissemination of mental health treatment in primary care.

Trends in treatment for patients with depression in general practice in Norway, 2009-2015: nationwide registry-based cohort study (The Norwegian GP-DEP Study)

Background

Depression is highly prevalent, but knowledge is scarce as to whether increased public awareness and strengthened government focus on mental health have changed how general practitioners (GPs) help their depressed patients. This study aimed to examine national time trends in GP depression care and whether trends varied regarding patient gender, age, and comorbidity.

Methods

Nationwide registry-based cohort study, Norway. The study population comprised all residents aged 20 years or older with new depression diagnoses recorded in general practice, 2009–2015. We linked reimbursement claims data from all consultations in general practice for depression with information on demographics and antidepressant medication. The outcome was type(s) of GP depression care during 12 months from the date of diagnosis: (long) consultation, talking therapy, antidepressant drug treatment, sickness absence certification, and referral to secondary mental health care. Covariates were patient gender, age, and comorbidity. The data are presented as frequencies and tested with generalized linear models.

Results

We included 365,947 new depression diagnoses. Mean patient age was 44 years (SD = 16), 61.9 % were women, 41.2 % had comorbidity. From 2009 to 2015, proportions of patients receiving talking therapy (42.3–63.4 %), long consultations (56.4–71.8 %), and referral to secondary care (16.6–21.6 %) increased, while those receiving drug treatment (31.3–25.9 %) and sick-listing (58.1–50 %) decreased. The trends were different for gender (women had a greater increase in talking therapy and a smaller decrease in sick-listing, compared to men), age (working-aged patients had a smaller increase in talking therapy, a greater increase in long consultations, and a smaller decrease in antidepressant drug use, compared to older patients) and comorbidity (patients with mental comorbidity had a smaller increase in talking therapy and a greater increase in long consultations, compared to those with no comorbidity and somatic comorbidity).

Conclusions

The observed time trends in GP depression care towards increased provision of psychological treatment and less drug treatment and sick-listing were in the desired direction according to Norwegian health care policy. However, the large and persistent differences in treatment rates between working-aged and older patients needs further investigation.

Psychologic Treatment of Depression Compared With Pharmacotherapy and Combined Treatment in Primary Care: A Network Meta-Analysis

PURPOSE

Most patients with depression are treated by general practitioners, and most of those patients prefer psychotherapy over pharmacotherapy. No network meta-analyses have examined the effects of psychotherapy compared with pharmacotherapy, combined treatment, care as usual, and other control conditions among patients in primary care.

METHODS

We conducted systematic searches of bibliographic databases to identify randomized trials comparing psychotherapy with pharmacotherapy, combined treatment, care as usual, waitlist, and pill placebo. The main outcome was treatment response (50% improvement of depressive symptoms from baseline to end point).

RESULTS

A total of 58 studies with 9,301 patients were included. Both psychotherapy and pharmacotherapy were significantly more effective than care as usual (relative risk [RR] for response = 1.60; 95% CI, 1.40-1.83 and RR = 1.65; 95% CI, 1.35-2.03, respectively) and waitlist (RR = 2.35; 95% CI, 1.57-3.51 and RR = 2.43; 95% CI, 1.57-3.74, respectively) control groups. We found no significant differences between psychotherapy and pharmacotherapy (RR = 1.03; 95% CI, 0.88-1.22). The effects were significantly greater for combined treatment compared with psychotherapy alone (RR = 1.35; 95% CI, 1.00-1.81). The difference between combined treatment and pharmacotherapy became significant when limited to studies with low risk of bias and studies limited to cognitive behavior therapy.

CONCLUSIONS

Psychotherapy is likely effective for the treatment of depression when compared with care as usual or waitlist, with effects comparable to those of pharmacotherapy. Combined treatment might be better than either psychotherapy or pharmacotherapy alone.

Primary Care Physician Recognition and Documentation of Depressive Symptoms Among Chinese and Latinx Patients During Routine Visits: A Cross-Sectional Study

Purpose: Asian and Latinx individuals have a high burden of untreated depression. Under-recognition of depressive symptoms may contribute to existing disparities in depression treatment. The objective of this cross-sectional study was to determine whether physicians recognize and treat depressive symptoms for Chinese and Latinx patients during routine primary care visits. Methods: We analyzed data from 1171 Chinese and Latinx patients who were interviewed within 1 week after a primary care visit in a large academic practice, which had not yet implemented universal depression screening. We included participants with depressive symptoms (defined as a Patient Health Questionaire-2 score ≥3) and no prior history of depression (N=118). We investigated whether patients perceived having a mental health need in the prior year and conducted chart reviews to assess provider recognition of depressive symptoms, defined as documentation of symptoms, antidepressant initiation, or mental health referral within 30 days of the visit. We further examined differences by race/ethnicity and language preference. Results: Among the 118 patients with depressive symptoms and no prior depression diagnosis (mean age 68), 71 (61%) reported a mental health need in the prior 12 months; however, providers recognized depressive symptoms in only 8/118 patients (7%). The number of patients with recognized symptoms was small across race/ethnicity and language preference groups and we found no significant differences. Conclusion: Physicians recognized and documented depressive symptoms for 1 in 10 Chinese and Latinx patients during routine primary care visits. Targeted efforts are needed to address under-recognition of symptoms and improve depression care for these populations.

Treating depressive symptoms among veterans in primary care: A multi-site RCT of brief behavioral activation

BACKGROUND

Behavioral activation is ideal for embedded behavioral health providers (BHPs) working in primary care settings treating patients reporting a range of depressive symptoms. The current study tested whether a brief version of Behavioral Activation (two 30-minute appointments, 2 boosters) designed for primary care (BA-PC) was more effective than primary care behavioral health treatment-as-usual (TAU) in reducing depressive symptoms and improving quality of life and functioning.

METHODS

Parallel-arm, multi-site randomized controlled trial. 140 Veterans were randomized to BA-PC or TAU and completed assessments at baseline, 6 weeks, 12 weeks, and 24 weeks.

RESULTS

Reductions in depressive symptoms were observed in both groups between baseline and 3-weeks prior to any treatment, with continued reductions among those in the BA-PC condition through 12-weeks. However, there was no significant condition X time interaction at 12-weeks. Quality of life and mental health functioning were significantly improved for those in the BA-PC condition, compared to TAU, at 12 weeks.

LIMITATIONS

Generalizability to a broader population may be limited as this sample consisted of veterans. Although engagement in TAU matched other prior work, it was lower than engagement in BA-PC, which also may compromise results.

CONCLUSIONS

Although this study found that both TAU and BA-PC participants showed a decline in depressive symptoms, improvements in functioning and quality of life within those assigned to BA-PC, strong treatment retention and feasibility of BA-PC, and significant reductions in depressive symptoms among those with more severe baseline depressive symptoms are encouraging and support continued research on BA-PC. This trial was registered in clinicaltrials.gov as Improving Mood in Veterans in Primary Care (NCT02276807).

GPs' drug treatment for depression by patients' educational level: registry-based study

Background

Antidepressant drugs are often prescribed in general practice. Evidence is conflicting on how patient education influences antidepressant treatment.

Aim

To investigate the association between educational attainment and drug treatment in adult patients with a new depression diagnosis, and to what extent sex and age influence the association.

Design & setting

A nationwide registry-based cohort study was undertaken in Norway from 2014–2016.

Method

The study comprised all residents of Norway born before 1996 and alive in 2015. Information was obtained on all new depression diagnoses in general practice in 2015 (primary care database) and data on all dispensed depression medication (Norwegian Prescription Database [NorPD]) 12 months after the date of diagnosis. Independent variables were education, sex, and age. Associations with drug treatment were estimated using a Cox proportional hazard model and performed separately for sex.

Results

Out of 49 967 patients with new depression (61.6% women), 15 678 were dispensed drugs (30.4% women, 33.0% men). Highly educated women were less likely to receive medication (hazard ratio [HR] = 0.93; 95% confidence interval [CI] = 0.88 to 0.98) than women with low education. No such differences appeared among men. Women aged 20–29 years were more likely to be treated with drugs than those aged 30–59 years, and women aged ≥70 years were more likely to receive drugs (HR = 1.65; 95% CI = 1.54 to 1.77) than those aged 20–29 years. The pattern was similar but less pronounced for men.

Conclusion

Educational differences in antidepressant therapy among women may reflect different treatment approaches that clinicians should be aware of to avoid unintended variation. Reasons for this variation and consequences for quality of treatment should be explored.

The efficacy of cognitive behavioral therapy for the treatment of antenatal depression: A systematic review

BACKGROUND

Antenatal depression affects 7-20% of pregnant women globally yet less than a fifth of such women receive adequate treatment. Cognitive behavioral therapy (CBT) is known to be effective in the treatment of depression. However, the research is more limited with regard to the antenatal period suggesting a need for clearer evidence within this field.

OBJECTIVE

To determine if CBT is effective in the treatment of antenatal depression.

METHODS

Medline, Embase, PsychINFO, CINAHL and CENTRAL were searched for studies that quantified the effectiveness of CBT in women with a confirmed diagnosis of antenatal depression. Randomised controlled trials that measured the effectiveness of CBT delivered during the antenatal period, compared to another intervention or usual care, measured using a validated depression score pre and post intervention were included.

RESULTS

Five RCTs were eligible for inclusion, all of which found a significant decrease in depression scores following CBT interventions, greater than that observed in control groups. Improvements in depressive scores were maintained long-term for participants who received CBT. Participant satisfaction with the interventions received was high.

LIMITATIONS

Studies included displayed major performance biases, and language bias is present due to exclusion of an Iranian paper.

CONCLUSION

CBT, tailored to pregnant women, is effective in the treatment of antenatal depression, with little difference in efficacy between CBT sub-types. Further large-scale RCTs are needed to confirm these hypotheses and determine the most cost-effective way of delivering CBT to pregnant women. There is also need for a specific, validated tool for assessing antenatal depression.

Polygenic risk scores: from research tools to clinical instruments

Genome-wide association studies have shown unequivocally that common complex disorders have a polygenic genetic architecture and have enabled researchers to identify genetic variants associated with diseases. These variants can be combined into a polygenic risk score that captures part of an individual's susceptibility to diseases. Polygenic risk scores have been widely applied in research studies, confirming the association between the scores and disease status, but their clinical utility has yet to be established. Polygenic risk scores may be used to estimate an individual's lifetime genetic risk of disease, but the current discriminative ability is low in the general population. Clinical implementation of polygenic risk score (PRS) may be useful in cohorts where there is a higher prior probability of disease, for example, in early stages of diseases to assist in diagnosis or to inform treatment choices. Important considerations are the weaker evidence base in application to non-European ancestry and the challenges in translating an individual's PRS from a percentile of a normal distribution to a lifetime disease risk. In this review, we consider how PRS may be informative at different points in the disease trajectory giving examples of progress in the field and discussing obstacles that need to be addressed before clinical implementation.

Clinical judgement, case complexity and symptom scores as predictors of outcome in depression: an exploratory analysis

BACKGROUND

Clinical guidelines for depression in adults recommend the use of outcome measures and stepped care models in routine care. Such measures are based on symptom severity, but response to treatment is likely to also be influenced by personal and contextual factors. This observational study of a routine clinical sample sought to examine the extent to which "symptom severity measures" and "complexity measures" assess different aspects of patient experience, and how they might relate to clinical outcomes, including disengagement from treatment.

METHODS

Subjects with symptoms of depression (with or without comorbid anxiety) were recruited from people referred to an established Primary Care Mental Health Team using a stepped care model. Each participant completed three baseline symptom measures (the Personal Health Questionnaire (PHQ), Generalised Anxiety Disorder questionnaire (GAD) and Clinical Outcomes in Routine Evaluation (CORE-10)), and two assessments of "case complexity" (the Minnesota-Edinburgh Complexity Assessment Measure (MECAM) and a local complexity assessment). Clinician perception of likely completion of treatment and patient recovery was also assessed. Outcome measures were drop out and clinical improvement on the PHQ.

RESULTS

298 subjects were recruited to the study, of whom 258 had a sufficient dataset available for analysis. Data showed that the three measures of symptom severity used in this study (PHQ, GAD and CORE-10) seemed to be measuring distinct characteristics from those associated with the measures of case complexity (MECAM, previous and current problem count). Higher symptom severity scores were correlated with improved outcomes at the end of treatment, but there was no association between outcome and complexity measures. Clinicians could predict participant drop-out from care with some accuracy, but had no ability to predict outcome from treatment.

CONCLUSIONS

These results highlight the extent to which drop-out complicates recovery from depression with or without anxiety in real-world settings, and the need to consider other factors beyond symptom severity in planning care. The findings are discussed in relation to a growing body of literature investigating prognostic indicators in the context of models of collaborative care for depression.

Depression Screening and Measurement-Based Care in Primary Care

The health issue addressed is the unmet need to universally screen and treat depression, which is one of the most common mental health disorders among adults in the United States. The US Preventive Services Task Force recommends screening adults for depression in primary care and using evidence-based protocols. This quality improvement project implemented VitalSign6, a measurement-based care program, to improve depression screening and treatment of adults in primary care at an academic medical center. A pre-post design was used to determine effectiveness of changes in screening, outcomes, and satisfaction. Of 1200 unique adult patients, 95.4% received initial screening. Providers diagnosed and administered measurement-based care to 236 patients. After 14 weeks, 27.5% returned for at least 1 follow-up. Results showed a statistically significant decrease in self-reported depression scores from baseline to follow-up. VitalSign6 was effective in improving identification and management of depression in primary care.

'I mean what is depression?' A qualitative exploration of UK general practitioners' perceptions of distinctions between emotional distress and depressive disorder

OBJECTIVE

Detection of depression is a key part of primary mental healthcare. However, determining whether depressive disorder is or is not present in primary care patients is complex. The aim of this qualitative study was to explore general practitioners' (GPs) perceptions of distinctions between emotional distress and depressive disorder.

DESIGN

Qualitative interview study.

SETTING

Face-to-face and telephone interviews with GPs from the South of England.

PARTICIPANTS

GPs working in UK primary care practices (n=21).

METHOD

Interviews followed a semi-structured interview guide, were audio recorded and transcribed. Data were analysed thematically.

RESULTS

Views were divergent when directly considering whether emotional distress could be distinguished from depressive disorder. Some GPs suggested a distinction was not possible as symptoms lay on a continuum, with severity as a proxy for disorder. Others focused on the difficulty of the distinction and were uncertain. Some GPs perceived a distinction and referred to emotional distress as more likely in the presence of a stressor with the absence of biological symptoms. It was also common for GPs to refer to endogenous and reactive depression when considering possible distinctions between distress and depressive disorder.

CONCLUSIONS

GPs' perceptions of when emotional symptoms reflect disorder varied greatly, with a broad range of views presented. Further research is needed to develop more consistent frameworks for understanding emotional symptoms in primary care.

Management of depressive symptoms in peri- and postmenopausal women: EMAS position statement

INTRODUCTION

Globally, the total number of people with depression exceeds 300 million, and the incidence rate is 70 % greater in women. The perimenopause is considered to be a time of increased risk for the development of depressive symptoms and major depressive episodes.

AIM

The aim of this position statement is to provide a comprehensive model of care for the management of depressive symptoms in perimenopausal and early menopausal women, including diagnosis, treatment and follow-up. The model integrates the care provided by all those involved in the management of mild or moderate depression in midlife women.

MATERIALS AND METHODS

Literature review and consensus of expert opinion.

SUMMARY RECOMMENDATIONS

Awareness of depressive symptoms, early detection, standardized diagnostic procedures, personalized treatment and a suitable follow-up schedule need to be integrated into healthcare systems worldwide. Recommended treatment comprises antidepressants, psychosocial therapies and lifestyle changes. Alternative and complementary therapies, although widely used, may help with depression, but a stronger evidence base is needed. Although not approved for this indication, menopausal hormone therapy may improve depressive symptoms in peri- but not in postmenopausal women, especially in those with vasomotor symptoms.

Rationale, design, and baseline data for a multicenter randomized clinical trial comparing depression screening strategies after acute coronary syndrome: The comparison of depression identification after acute Coronary Syndromes-Quality of Life and Cost Outcomes (CODIACS-QOL) trial

BACKGROUND

Elevated depressive symptoms among survivors of acute coronary syndromes (ACS) confer recurrent cardiovascular events and mortality, worse quality of life, and higher healthcare costs. While multiple scientific groups advise routine depression screening for ACS survivors, no randomized trials exist to inform this screening recommendation. We aimed to assess the effect of screening for depression on change in quality of life over 18 months among ACS patients.

METHODS

The Comparison of Depression Identification after Acute Coronary Syndrome on Quality of Life and Cost Outcomes (CODIACS-QoL) trial is a pragmatic, 3-arm trial that randomized ACS patients to 1) systematic depression screening using the 8-item Patient Health Questionnaire (PHQ-8) and if positive screen (PHQ-8 ≥ 10), notification of primary care providers (PCPs) and invitation to participate in centralized, patient-preference, stepped depression care (Screen, Notify, and Treat, N = 499); 2) systematic depression screening and PCP notification only (Screen and Notify, N = 501); and 3) usual care (No Screen, N = 500). Adults hospitalized for ACS in the previous 2-12 months without prior history of depression were eligible for participation. Key outcomes will be quality-adjusted life years (primary), cost of health care utilization, and depression-free days across 18 months.

RESULTS

A total of 1500 patients were randomized in the CODIACS-QOL trial (28.3% women; 16.3% Hispanic; mean age 65.9 (11.5) years). Only 7% of ACS survivors had elevated depressive symptoms.

CONCLUSIONS

Using a novel randomization schema and pragmatic design principles, the CODIACS-QoL trial achieved its enrollment target. Eventual results of this trial will inform future depression screening recommendations in cardiac patients.

Depression in primary care: part 1-screening and diagnosis

Depression is a common and heterogeneous condition with a chronic and recurrent natural course that is frequently seen in the primary care setting. Primary care providers play a central role in managing depression and concurrent physical comorbidities, and they face challenges in diagnosing and treating the condition. In this two part series, we review the evidence available to help to guide primary care providers and practices to recognize and manage depression. In this first of two reviews, we outline an approach to screening and diagnosing depression in primary care that evaluates current evidence based guidelines and applies the recommendations to clinical practice. The second review presents an evidence based approach to the treatment of depression in primary care, detailing the recommended lifestyle, drug, and psychological interventions at the individual level. It also highlights strategies that are being adopted at an organizational level to manage depression more effectively in primary care.
