Depression Treatment Non-adherence and its Psychosocial Predictors: Differences between Young and Older Adults?

Discrete Choice Experiments to Elicit Patient Preferences for the Treatment of Major Depressive Disorder: A Systematic Review

BACKGROUND

Individual preferences for treatment options for major depressive disorder can impact therapeutic decision making, adherence, and ultimately outcomes.

OBJECTIVES

This systematic review of discrete choice experiments (DCEs) on patient preferences for major depressive disorder treatment assessed the range of DCE applications in major depressive disorder to document patient stakeholder involvement in DCE development and to identify the relative importance of treatment attributes.

METHODS

We searched MEDLINE via Ovid (1946-present), EMBASE (Elsevier interface), Cochrane Central Register of Controlled Trials (Wiley interface), and PsycINFO (EBSCO interface) databases on 29 May, 2024. Covidence software facilitated the review, which four members completed independently. The review was conducted in two phases: title and abstract and then a full-text review. We used an established quality reporting tool to evaluate selected articles. The Covidence extraction tool was adapted for this study.

RESULTS

A total of 19 articles were included in this review. Most studies elicited preferences for depression treatment (63.2%) and care delivery (10.5%). Two assessed willingness to pay. Individuals prefer a combination of medicine and counseling over each treatment alone. Treatment efficacy, relapse prevention, and symptom relief were among the most important attributes. Individuals were willing to accept larger risks to achieve symptom improvement. Few studies examined preference heterogeneity with latent subgroups.

CONCLUSIONS

Discrete choice experiments for major depressive disorder treatment preferences enable an assessment of trade-offs for first-line therapeutic options. Patient stakeholders are infrequently involved as collaborators in the DCE development. Few examined preference heterogeneity among subgroups.

Cognitive Decline and Its Associated Factors in Patients with Major Depressive Disorder

Background: Major Depressive Disorder (MDD) is a significant and common mental health problem occurring worldwide. Cognitive decline is frequently observed during acute and residual phases of MDD, contributing significantly to functional impairment. The aim of this study was to determine the clinical profile and correlates of cognitive decline amongst adult outpatients with MDD. Methods: The survey was cross-sectional in design. A systematic random sampling method was used to recruit patients. Confirmation of MDD was achieved by using the Mini International Neuropsychiatric Interview (M.I.N.I 7.0). Cognitive decline was measured using the Montreal Cognitive Assessment (MoCA). Descriptive analysis was performed, followed by univariate and multiple logistic regression analyses. Results: Out of 245 patients, 32.7% (n = 80, 95% CI: 26.7, 38.6) had cognitive decline. Multiple logistic regression showed the existence of cognitive decline amongst MDD patients, which was significantly associated with those having secondary and lower levels of education (OR: 6.09; 95% CI: 2.82, 13.16; p < 0.001), five or more depressive episodes (OR: 8.93; 95% CI: 3.24, 24.67; p < 0.001), treatment non-compliance (OR: 3.48; 95% CI: 1.40, 6.59; p = 0.003), and medical comorbidity (OR: 2.74; 95% CI: 1.46, 5.18; p = 0.002). Conclusions: Cognitive decline is a prevalent condition among outpatients with MDD. Clinicians need to be cognizant about measures of cognition and related risk factors. Timely control of both depression and medical comorbidities would be a reasonable approach to improve functional outcomes in MDD patients.

Preferences for Treatments for Major Depressive Disorder: Formative Qualitative Research Using the Patient Experience

OBJECTIVES

The goals of this formative research are to elicit attributes of treatment and desired outcomes that are important to individuals with major depressive disorder (MDD), to develop a stated preference instrument, and to pre-test the instrument.

METHODS

A three-phase survey study design elicited the patient's journey with MDD to design and pre-test the discrete choice experiment (DCE) instrument. Participants were 20 adults aged ≥ 18 with MDD who did not also have bipolar disorder or post-partum depression. We engaged patient advocates and a multi-disciplinary stakeholder advisory group to select and refine attributes for inclusion in a DCE instrument. The DCE was incorporated into a survey that also collected depression treatment and management and sociodemographic characteristics. The DCE was pre-tested with ten adults with MDD.

RESULTS

Six attributes were included in the DCE: mode of treatment (medicine only, psychotherapy only, all modalities including brain stimulation), time to treatment effect (6, 9, 12 weeks), days of hopefulness (2, 4, 6 days/week), effect on productivity (40%, 60%, 90% increase), relations with others (strained, improved, no impact), and out-of-pocket costs ($30, $60, $90/month). The DCE test led to the refinement of mode of treatment (medicine, medicine and psychotherapy, and all modalities); time to treatment effect (4, 6, 9 weeks); monthly out-of-pocket costs ($30, $90, $270).

CONCLUSIONS

MDD treatment preferences revealed trade-offs among mode of treatment, time to treatment effect, functional outcomes, and cost. The findings demonstrate the potential for meaningfully incorporating the patient experience in preference measures.

Annual costs among patients with major depressive disorder and the impact of key clinical events

BACKGROUND: The economic burden of major depressive disorder (MDD) is substantial and increasing; however, the impact of key clinical events (eg, hospitalization, suicide attempt/ideation, and treatment changes) on health care resource use and costs are less established. OBJECTIVE: To evaluate the health care utilization and costs among patients with MDD, particularly for those with key clinical events. METHODS: In this retrospective analysis, administrative health care claims from the IBM MarketScan Commercial Claims and Encounters Database were used to identify adults with a new diagnosis of MDD (January 1, 2009, to December 31, 2017). Patients with 12 months or more of continuous health care coverage before and after the initial medical claim with an MDD diagnosis (index date) and 1 or more pharmacy claims for an antidepressant within 60 days of any qualifying medical claim were included. The effect of post-index date key clinical events (eg, treatment changes, moderate to severe MDD, MDD-related emergency department [ED] visits, MDD-related hospitalizations, suicide attempt/ideation, severe mental health disorder, use of brain stimulation therapies) on all-cause total costs was assessed. Actual allcause costs were summarized descriptively and reported per patient per year (PPPY). Multivariable analyses compared differences in all-cause costs during follow-up, depending on whether patients experienced a key clinical event. RESULTS: A total of 455,082 patients met eligibility criteria. The average age was 41 years and 64% of patients were female. Mean (SD) all-cause PPPY costs during the follow-up period were $10,074 ($25,694). The most common key clinical events were treatment changes, moderate to severe MDD diagnosis, and MDD-related ED visits. The majority of patients (90.1%) experienced at least 1 treatment change, which was most commonly treatment discontinuation. Generally, mean costs for up to 90 days following an event were higher than those preceding the event. In multivariable analyses, patients with any key clinical events had 51% higher PPPY allcause health care costs compared with those who did not have any key clinical events. Compared with patients without key clinical events, follow-up costs were more than 2 times higher among patients with severe mental health disorder, MDD-related hospitalization, and suicide attempt/ideation. The most impactful key clinical event was treatment with electroconvulsive therapy, vagal nerve stimulation, or transcranial magnetic stimulation, in which patients incurred 4.3 times higher follow-up costs than those who did not receive one of these treatments. CONCLUSIONS: Key clinical events exacerbate health care resource use and costs among patients with MDD. Effective therapeutic regimens initiated optimally in the course of treatment may mitigate costly clinical events associated with MDD.

Comparing cardiovascular disease incidence and prevalence between depressed and non-depressed older persons over time: Cohort differences in the Longitudinal Aging Study Amsterdam

OBJECTIVE

Previous studies suggest that prevention of cardiovascular disease (CVD) is more difficult in depressed persons. Although the prevalence and incidence of CVD decreased over the past decades, it is uncertain whether this is also true for depressed persons. This study examined whether changes in the prevalence and incidence of CVD differ between depressed and non-depressed older persons.

METHODS

Longitudinal data from three community-based representative birth cohorts aged 55-65 years of the Longitudinal Aging Study Amsterdam were used; N = 1070 born in 1926-1937, N = 995 born in 1938-1947, N = 1019 born in 1948-1957. The outcome included fatal and non-fatal CVD. Depression was defined as ≥16 points on the Center for Epidemiological Studies Depression Scale or a general practitioner's diagnosis of depression. Data were analysed with for age and sex adjusted logistic regression and cox regression models.

RESULTS

Comparing cohort 2 and 3 with cohort 1 in the complete sample, the prevalence of CVD decreased by 2% (OR = 0.98, 95%CI = 0.76-1.26) and 32% (OR = 0.68, 95%CI = 0.52-0.89), respectively, and the three-year incidence of CVD decreased by 6% (OR = 0.94, 95%CI = 0.63-1.41) and 26% (OR = 0.74, 95%CI = 0.48-1.15), respectively. The 13-year incidence of CVD decreased by 19% (HR = 0.81, 95%CI = 0.67-0.99) in cohort 2 compared to cohort 1. These decreases did not differ statistically significantly between depressed and non-depressed respondents (p-values of interaction terms: 0.35-0.98).

CONCLUSION

Substantial decreases in the prevalence and incidence of CVD were observed in depressed and non-depressed older persons. Although this is encouraging, cardiovascular risk remained higher in depressed persons over time, warranting tailored prevention programs for depressed older persons.

Effectiveness and Acceptability of Low-intensity Psychological Interventions on the Well-being of Older Adults: A Systematic Review

Objectives: Growth in the older adult population and healthcare inequities mean there is a global need to increase access to early intervention in mental healthcare for older adults. This systematic review synthesized the evidence for the efficacy and acceptability of low-intensity psychological interventions (self-help, psychoeducation, bibliotherapy, internet cognitive-behavioral therapy: iCBT) for older adults with mild-to-moderate mental health problems.Methods: Ovid, EBSCOhost and ProQuest were searched for articles describing low-intensity psychological interventions. Pre and post outcome measures and a mean age of at least 50 (age range ≥40) were required for inclusion.Results: 26 articles (23 studies) described various interventions. Most studies were good quality and reported improvements in participant's mental health scores post intervention. Participants were more likely to be female, aged 60-70 and to be highly educated. Eight studies reported obtaining participant satisfaction ratings. Three studies included participants from rural areas.Conclusions: Low-intensity psychological interventions can be effective for older adults with mild-to-moderate mental health problems, but generalizability is constrained.Clinical Implications: Guided iCBT and bibliotherapy may be beneficial for adults in their 60s and 70s experiencing mild-to-moderate levels of depression. CBT may also be beneficial for reducing symptoms of mild-to-moderate anxiety. Providing the option of low-intensity psychological intervention, particularly iCBT, may help increase engagement with treatment.

Satisfaction With Patient Engagement and Self-Reported Depression Among Hospitalized Patients: A Propensity-Score Matching Analysis

BACKGROUND

Depression is common among hospitalized patients and poses a significant threat to their quality of life. Patient engagement (PE) in healthcare has been shown to be associated with positive health outcomes. However, the relationship between PE and depression among hospitalized patients, with and without chronic conditions, has not yet been explored. This study aimed to investigate the association between patients' satisfaction with PE and self-reported depression in Chinese public hospitals.

METHOD

A multi-centered, cross-sectional survey was conducted in seven tertiary-level public hospitals in Guangdong province, China. Twelve items from a patient-centered care questionnaire and the Patient Health Questionnaire 2-item version were used were used to assess patients' satisfaction with PE and self-reported depression, respectively. Propensity score matching (PSM) approach was used to reduce selection bias and potential baseline differences between patients with and without chronic conditions. The relationship between satisfaction with PE and depression was assessed, using univariate and multivariate logistic regression analyses, respectively.

RESULTS

A total of 1,974 hospitalized patients participated in the survey. After the PSM procedure, 604 patients were assigned to the chronic condition group, and another 604 patients were successfully matched in the comparison group with no differences in sex, age, educational level, and PE-related characteristics. Univariate logistic regression analysis indicated that high satisfaction with PE-related approaches significantly decreased the probability of developing depressive status. Multivariate logistic regression analysis further indicated that, after adjusting all PE-related approaches, "patient education" and "involvement in discharge planning" could significantly decrease the probability of patients developing depression.

CONCLUSIONS

Our results indicate that encouraging PE and improving patients' satisfaction with PE interventions in clinical practice led to improved mental health outcomes among hospitalized patients in China.

Acceptability and fidelity of a psychosocial intervention (PROACTIVE) for older adults with depression in a basic health unit in São Paulo, Brazil: a qualitative study

Background

Depression is a common condition in older adults, being often detected and treated initially in primary care. Collaborative care models including, for example, task-shifting and stepped-care approaches have been investigated to overcome the current scarcity of strategies and trained mental health professionals to treat depression. The PROACTIVE study developed a psychosocial intervention, which makes extensive use of technology in an intervention delivered mainly by non-specialists to treat older adults with depression. The aim of this qualitative study is to assess: 1. Health workers’ fidelity to the intervention protocol; 2. Acceptability of the psychosocial intervention from the viewpoint of older adult participants; and 3. Perceptions of the psychosocial intervention by the health workers.

Methods

Qualitative methods were used to achieve our aims. The sample included participants (N = 31) receiving the intervention in the pilot trial and health workers (N = 11) working in a Basic Health Unit in the northern area of São Paulo, Brazil. Focus group, non-participant observation and structured interviews were used. Data were analysed using a thematic analysis approach.

Results

1. Health workers’ fidelity to the intervention protocol: training, supervision and the structured intervention were crucial and guaranteed health workers’ fidelity to the protocol. 2. Acceptability of the psychosocial intervention from the viewpoint of older adult participants: Collaborative care, task-shifting, and stepped-care approaches were well accepted. The structured protocol of the intervention including different activities and videos was important to adherence of older adult participants 3. Perceptions of the psychosocial intervention by the health workers: It was feasible to have the home psychosocial sessions conducted by health workers, who are non-mental health specialists and received 3-day training. Training and supervision were perceived as crucial to support health workers before and during the intervention. Technology served as a tool to structure the sessions, obtain and store patient data, present multi-media content, guarantee fidelity to the protocol and facilitate communication among members of the team. However, extra burden was mentioned by the health workers indicating the need of adjustments in their daily duties.

Conclusions

The PROACTIVE intervention was demonstrated to be feasible and accepted by both health workers and older adult participants. The qualitative assessments suggested improvements in training and supervision to ensure fidelity to protocol. To assess effectiveness a randomised controlled trial of the intervention will be conducted with the addition of improvements suggested by this qualitative study.

Examining the Effectiveness of Gamification in Mental Health Apps for Depression: Systematic Review and Meta-analysis

BACKGROUND

Previous research showed that computerized cognitive behavioral therapy can effectively reduce depressive symptoms. Some mental health apps incorporate gamification into their app design, yet it is unclear whether features differ in their effectiveness to reduce depressive symptoms over and above mental health apps without gamification.

OBJECTIVE

The aim of this study was to determine whether mental health apps with gamification elements differ in their effectiveness to reduce depressive symptoms when compared to those that lack these elements.

METHODS

A meta-analysis of studies that examined the effect of app-based therapy, including cognitive behavioral therapy, acceptance and commitment therapy, and mindfulness, on depressive symptoms was performed. A total of 5597 articles were identified via five databases. After screening, 38 studies (n=8110 participants) remained for data extraction. From these studies, 50 total comparisons between postintervention mental health app intervention groups and control groups were included in the meta-analysis.

RESULTS

A random effects model was performed to examine the effect of mental health apps on depressive symptoms compared to controls. The number of gamification elements within the apps was included as a moderator. Results indicated a small to moderate effect size across all mental health apps in which the mental health app intervention effectively reduced depressive symptoms compared to controls (Hedges g=-0.27, 95% CI -0.36 to -0.17; P<.001). The gamification moderator was not a significant predictor of depressive symptoms (β=-0.03, SE=0.03; P=.38), demonstrating no significant difference in effectiveness between mental health apps with and without gamification features. A separate meta-regression also did not show an effect of gamification elements on intervention adherence (β=-1.93, SE=2.28; P=.40).

CONCLUSIONS

The results show that both mental health apps with and without gamification elements were effective in reducing depressive symptoms. There was no significant difference in the effectiveness of mental health apps with gamification elements on depressive symptoms or adherence. This research has important clinical implications for understanding how gamification elements influence the effectiveness of mental health apps on depressive symptoms.

Depression and Associated Factors in Chinese Patients With Chronic Kidney Disease Without Dialysis: A Cross-Sectional Study

Background: Chronic kidney disease (CKD) has been a globally public health problem over the past decades. The maintenance of physical and mental health is of importance for patients nowadays. Notably, depression is prevalent and associated with various adverse events in CKD patients without dialysis. Prior studies have reported that pain, negative illness perception, pain, and low self-esteem are potential risk factors of depression, while few studies have comprehensively investigated the mechanisms among these factors and depression among this population.

Purpose: This study aims to investigate the prevalence of depression and further explore the factors associated with depression among CKD patients without dialysis in China.

Design and Methods: We conducted a cross-sectional study in patients with diagnosed CKD to investigate the prevalence of depression was by the Beck Depression Inventory-II (BDI-II). The data on pain interference, illness perception, and self-esteem were also collected via self-administered questionnaires. A structural equation model (SEM) was used to examine the factors associated with depression.

Main Findings: From June to October 2019, we successfully interviewed 334 CKD patients at the outpatient clinics. Their mean age was 45.6 years (ranging from 19 to 74 years), and 48.5% were male. Most respondents were at early CKD stages (77.5% stage 1–3) and the prevalence of depression was 22.2%. We found a moderate association between illness perception and depression, which was modified by self-esteem. Similar but weaker association was found between pain interference and depression.

Conclusion and Recommendations: Negative illness perception, low self-esteem and severe pain interference were associated with depression among Chinese CKD patients without dialysis. Future studies are warranted to investigate the underlying mechanism and formulate the intervention strategies for this high-risk population.

Factors associated with loss to follow-up of outpatients with depression in general hospitals

Objective

We aimed to understand the reasons behind outpatient loss to follow-up and the views of Chinese patients with depression regarding disease diagnosis and antidepressant therapy.

Methods

Consecutive outpatients with newly diagnosed depressive disorder between September 2012 and August 2013 at the Shanghai First People’s Hospital (a tertiary hospital) were categorized into follow-up and lost-to-follow-up groups. We collected information on demographics, the Hamilton depression (HAMD) scale, Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale, and Symptom Checklist-90. Patients were routinely followed at 2, 4, 8, and 12 weeks. Any missed appointment was considered lost to follow-up.

Results

After 12 weeks of treatment, only 42.2% (70/166) of patients were continuing follow-up. Patients lost to follow-up were significantly younger (median, 42.5 vs. 56.5 years), had different marital status, higher education level, higher SDS score (43.8 ± 10.8 vs. 40.2 ± 10.9), and higher HAMD score (median, 21 vs. 19). Age (odds ratio (OR) = 0.97, 95% confidence interval (CI): 0.95–0.997), and HAMD score (OR = 1.14, 95% CI: 1.01–1.29) were independently associated with loss to follow-up.

Conclusion

Young age, higher HAMD score, and poor knowledge of depression and treatment were the main factors associated with loss to follow-up during depression management among our Chinese patients.

The Relationship between Terminology Preferences, Empowerment and Internalised Stigma in Mental Health

People with a mental illness may be exposed to stigma which, when internalised, negatively influences self-esteem, personal goal attainment and quality of life. However, people who are empowered may actively challenge stigma by engaging in meaningful opportunities, furthering their self-worth as they achieve control within their lives. People who are empowered through active treatment participation are more likely to reach recovery goals and experience the benefits of evidence-based practices. Hence, empowerment can be viewed as essential to the recovery and well-being of people with a mental illness. Participants in this quantitative study (N = 173) were diagnosed with a mental illness and were recruited via convenience sampling from mental health support groups in Australia. Internalised stigma was less common and empowerment more prevalent in this study than was found in previous studies. However high internalised stigma and low empowerment were present. The terms 'individual' and 'person with lived experience' which have been identified as the preferred terms in a previous study were highlighted as both empowering and recovery focussed.

Prevalence, Barriers, and Interventions Related to Medication Adherence Among Patients With Major Depressive Disorder: A Scoping Review

The current scoping review aimed to identify the prevalence, contributing factors, methods of measurement, and interventions related to medication adherence among patients with major depressive disorder (MDD). A total of 37 articles met inclusion criteria. The prevalence of medication adherence among patients with MDD ranged from 10.6% to 85.4%. Approximately 67% of studies used self-report data collection. Illness-related factors (e.g., onset of illness, duration of illness, symptoms, illness severity), medication-related factors (e.g., adverse reactions, duration of treatment, cost of treatment), and patient-related factors (e.g., beliefs, attitudes, knowledge, self-stigma) were the most reported factors associated with medication adherence. In addition, multi-faceted interventions were recommended over single-element interventions to enhance medication adherence. There is a need to integrate appropriate and effective assessment measures of medication adherence that lead to better health care outcomes, lower risk factors, and improved interventions related to medication adherence.

Psychopathology and HIV diagnosis among older adults in the United States: disparities by age, sex, and race/ethnicity

In 2016, 17% of new HIV infections in the US were among adults aged 50 and older. Differences by age, sex, and race/ethnicity exist among older people living with HIV. Co-morbid mental health and substance use disorders (SUD) are also major challenges for this population. This study examined the association between generalized anxiety disorder (GAD), posttraumatic stress disorder (PTSD), SUD, depression, and HIV diagnosis among adults aged 50 and older, and the disparities by age, sex, and race/ethnicity. Data were obtained from Cerner Corporation's Health Facts® database. Multivariable logistic regression models were used to determine the associations between GAD, PTSD, SUD, and depression, and HIV diagnosis. Results were also stratified by age group, sex, and race/ethnicity. Overall, there were positive associations between SUD, depression, GAD, PTSD and HIV; and differences by age, sex and race/ethnicity existed in these associations. For example, after adjusting for age, race/ethnicity and marital status, men who were diagnosed with GAD were 10 times more likely (adjusted OR: 10.3; 95% CI: 8.75 - 12.1) to have an HIV diagnosis compared to men who were not diagnosed with GAD. Women who were diagnosed with GAD were five times more likely (adjusted OR: 5.01; 95% CI: 3.81 - 6.58) to have an HIV diagnosis compared to women who were not diagnosed with GAD. HIV prevention and intervention programs for older adults should address GAD, PTSD, SUD and depression and consider the age, sex and racial/ethnic disparities in the association between psychopathology and HIV.

The Safety, Efficacy, and Tolerability of Microbial Ecosystem Therapeutic-2 in People With Major Depression and/or Generalized Anxiety Disorder: Protocol for a Phase 1, Open-Label Study

BACKGROUND

The bidirectional signaling between the gut microbiota and the brain, known as the gut-brain axis, is being heavily explored in current neuropsychiatric research. Analyses of the human gut microbiota have shown considerable individual variability in bacterial content, which is hypothesized to influence brain function, and potentially mood and anxiety symptoms, through gut-brain axis communication. Preclinical and clinical research examining these effects suggests that fecal microbiota transplant (FMT) may aid in improving the severity of depression and anxiety symptoms by recolonizing the gastrointestinal (GI) tract with healthy bacteria. The microbial ecosystem therapeutic (ie, microbial ecosystem therapeutic-2 [MET-2]) used in this study is an alternative treatment to FMT, which comprises 40 different strains of gut bacteria from a healthy donor.

OBJECTIVE

The primary objective of this study is to assess subjective changes in mood and anxiety symptoms before, during, and after administration of MET-2. The secondary objectives of this study are to assess the changes in metabolic functioning and the level of repopulation of healthy gut bacteria, the safety and tolerability of MET-2, and the effects of early stress on biomarkers of depression/anxiety and the response to treatment.

METHODS

Adults experiencing depressive or anxiety symptoms will be recruited from the Kingston area. These participants will orally consume an encapsulated MET-2 once daily-containing 40 strains of purified and laboratory-grown bacteria from a single healthy donor-for 8 weeks, followed by a 2-week treatment-free follow-up period. Participants will undergo a series of clinical assessments measuring mood, anxiety, and GI symptoms using validated clinical scales and questionnaires. Molecular data will be collected from blood and fecal samples to assess metabolic changes, neurotransmitter levels, inflammatory markers, and the level of engraftment of the fecal samples that may predict outcomes in depression or anxiety.

RESULTS

Given the association between the gut bacteria and the risk factors of depression, we expect to observe an improvement in the severity of depressive and anxiety symptoms following treatment, and we expect that this improvement is mediated by the recolonization of the GI tract with healthy bacteria. The recruitment for this study has been completed, and the data obtained are currently being analyzed.

CONCLUSIONS

This is the first time MET-2 is being tested in psychiatric indications, specifically depression and anxiety. As such, this may be the first study to show the potential effects of microbial therapy in alleviating psychiatric symptoms as well as its safety and tolerability.

Comparative effectiveness of three exercise types to treat clinical depression in older adults: A systematic review and network meta-analysis of randomised controlled trials

BACKGROUND

Few studies have directly compared the effects of different exercise therapies on clinical depression in older adults. Thus, we conducted a systematic review and network meta-analysis of current evidence from randomised controlled trials (RCTs) to compare the effectiveness of three major exercise types (aerobic, resistance, and mind-body exercise) in clinically depressed older adults.

METHODS

We followed PRISMA-NMA guidelines and searched databases for eligible RCTs (inception - September 12^th, 2019). RCTs were eligible if they included clinically depressed adults aged >65 years, implemented one or more exercise therapy arms using aerobic, resistance, or mind-body exercise, and assessed depressive symptoms at baseline and follow-up using a validated clinical questionnaire.

RESULTS

A network meta-analysis was performed on 15 eligible RCTs comprising 596 participants (321 treatment and 275 controls), including aerobic (n = 6), resistance (n = 5), and mind-body (n = 4) exercise trials. Compared with controls, mind-body exercise showed the largest improvement on depressive symptoms (g = -0.87 to -1.38), followed by aerobic exercise (g = -0.51 to -1.02), and resistance exercise (g = -0.41 to -0.92). Notably, there were no statistically significant differences between exercise types: aerobic versus resistance (g = -0.10, PrI = -2.23, 2.03), mind-body versus aerobic (g = -0.36, PrI = -2.69, 1.97), or mind-body versus resistance (g = -0.46, PrI = -2.75, 1.83).

CONCLUSIONS

These findings should guide optimal exercise prescription for allied health professionals and stakeholders in clinical geriatrics. Notably, clinically depressed older adults may be encouraged to self-select their preferred exercise type in order to achieve therapeutic benefit on symptoms of depression. In coalition with high levels of compliance, these data provide encouraging evidence for the antidepressant effect of either aerobic, resistance, or mind-body exercise as effective treatment adjucts for older adults presenting with clinical depression.

Placebo-To be or not to be? Are there really alternatives to placebo-controlled trials?

Recent success of established treatment has driven concerns about the ethics of using placebo-controlled trials in psychiatry. Active-controlled (superiority or non-inferiority) trials do not include a placebo-arm and thus avoid the associated ethical concerns but show disadvantages in other respects. The aim of this paper is to review the available literature and critically discuss the evidence regarding the use of placebo-controlled- versus active-controlled trials. A MEDLINE/PubMed and Google Scholar search was performed. Studies included focused on the deliberation on placebo-controlled- versus active-controlled trials. Twenty-six studies were included. The most cited benefits of placebo-controlled trials were greater scientific reliability of the results and no average impact on patients' health. Disadvantages were mainly related to withholding effective treatment and limited generalizability. The most frequent argument in favor of active-controlled trials is the lower chance of receiving ineffective medication during the trial. Downsides include larger sample sizes, higher costs and lower scientific reliability of results. Most authors agree that all trial designs are relevant to psychiatric research depending on study goals. Whatsoever, data does not support forgoing placebo-controlled trials. Expert consensus is warranted to permit drawing conclusions on the debate on the relevance of placebo-controlled trials.

Attitude and perceptions of patients towards long acting depot injections (LAIs)

BACKGROUND

Despite the well-established efficacy of the long acting depot injectable (LAIs) antipsychotics, these are significantly underused and underutilized by the mental health professionals, with a belief that patients will not accept the same.

AIMS & OBJECTIVES

To explore the acceptability and perception of patients towards various psychiatric treatments, with specific focus on LAIs. Additionally the study aimed to compare the acceptability of various types of treatments including LAIs between patients with severe mental disorders (Psychotic disorders and Bipolar disorder) and those with Common mental disorders (Anxiety, neurotic and depressive disorders).

METHODOLOGY

A self-designed semi-structured questionnaire was used to evaluate the preferred treatment options of all the new patients attending the psychiatry outpatient clinic of a tertiary care hospital. Depending on the response, they were further probed for the reasons for accepting or rejecting the LAIs.

RESULTS

2659 patients were interviewed who were divided into two groups (Group I - 321 subjects with psychotic disorders and 120 subjects with bipolar affective disorder (BPAD) and Group II - 2218 subjects with neurotic, stress-related and unipolar depressive disorders). More than three-fourth (78.8%) of the participants in the whole study sample opted for tablets only as their first preferred choice and injectables were opted by about 5% of the participants only, with no significant difference between the 2 groups. After being explained about LAIs, one fourth of the participants (24.9%) reported that they may consider LAIs, without any significant difference between the 2 groups. Among those who refused to take LAIs even after explanation, the commonly reported reasons were difficulty in visiting hospital frequently for the injectables (41.69%), injectables being painful (19.41%), fear of injections (13.96%), no need to take LAIs (12.45%) and preference to take some other types of medicines (8.52%).

CONCLUSIONS

Considering the fact that LAIs are highly underused in patients with severe mental disorders and there is lack of awareness about LAIs among patients with severe mental disorders, the present study findings suggest that there is reasonable level of acceptance of LAIs among patients with severe mental disorders when explained about the same.

Socioeconomic determinants affecting the access and utilization of depression care services in immigrants: A population-based study

BACKGROUND

It is imperative to address the health problems faced by immigrants in their destination countries in light of the current magnitude of migration processes worldwide. We aimed to evaluate the socioeconomic determinants of healthcare utilization in immigrants with depression.

METHOD

A population-based cohort comprising all immigrants who were eligible for National Health Insurance coverage (permanent residents, marriage immigrants, and naturalized citizens) using the National Health Insurance Claims Database in 2011-2013 was established. Cases were defined as immigrants with new-onset depression. Controls were new-onset Korean patients with depression matched by age, sex, and Charlson comorbidity index in a 1:2 ratio. Appropriateness of care (AOC) was defined as visiting a clinic for depression management at least 3 times in the first 12 weeks and 4 times thereafter until 12 months post-cohort entry.

RESULTS

A total of 2,378 immigrants and 4,756 matched Korean patients were identified. Of the immigrants, 30.0% achieved AOC, in contrast to 38.7% of Koreans (p < .0001). Adjusting for possible covariates, AOC was less likely for immigrants (adjusted OR (aOR), 0.760; 95% CI: 0.670-0.863). Medical Aid (aOR, 2.309; 95% CI, 1.479-3.610), rural residence (aOR, 1.536; 95% CI, 1.054-2.237), the presence of a psychiatric comorbidity (aOR, 1.912; 95% CI, 1.484-2.463), and visiting a psychiatrist (aOR, 2.387; 95% CI, 1.821-3.125) were associated with an increased likelihood of AOC in immigrants.

CONCLUSION

Socioeconomic determinants included insurance type (Medical Aid and National Health Insurance), place of residence, psychiatric comorbid status, doctor specialty, easy access to medical services (clinic-based), and a SSRI-based treatment regimen. Those predictors should be taken into account when developing healthcare strategies for immigrants.

Technological Interventions for Medication Adherence in Adult Mental Health and Substance Use Disorders: A Systematic Review

BACKGROUND

Medication adherence is critical to the effectiveness of psychopharmacologic therapy. Psychiatric disorders present special adherence considerations, notably an altered capacity for decision making and the increased street value of controlled substances. A wide range of interventions designed to improve adherence in mental health and substance use disorders have been studied; recently, many have incorporated information technology (eg, mobile phone apps, electronic pill dispensers, and telehealth). Many intervention components have been studied across different disorders. Furthermore, many interventions incorporate multiple components, making it difficult to evaluate the effect of individual components in isolation.

OBJECTIVE

The aim of this study was to conduct a systematic scoping review to develop a literature-driven, transdiagnostic taxonomic framework of technology-based medication adherence intervention and measurement components used in mental health and substance use disorders.

METHODS

This review was conducted based on a published protocol (PROSPERO: CRD42018067902) in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses systematic review guidelines. We searched 7 electronic databases: MEDLINE, EMBASE, PsycINFO, the Cochrane Central Register of Controlled Trials, Web of Science, Engineering Village, and ClinicalTrials.gov from January 2000 to September 2018. Overall, 2 reviewers independently conducted title and abstract screens, full-text screens, and data extraction. We included all studies that evaluate populations or individuals with a mental health or substance use disorder and contain at least 1 technology-delivered component (eg, website, mobile phone app, biosensor, or algorithm) designed to improve medication adherence or the measurement thereof. Given the wide variety of studied interventions, populations, and outcomes, we did not conduct a risk of bias assessment or quantitative meta-analysis. We developed a taxonomic framework for intervention classification and applied it to multicomponent interventions across mental health disorders.

RESULTS

The initial search identified 21,749 results; after screening, 127 included studies remained (Cohen kappa: 0.8, 95% CI 0.72-0.87). Major intervention component categories include reminders, support messages, social support engagement, care team contact capabilities, data feedback, psychoeducation, adherence-based psychotherapy, remote care delivery, secure medication storage, and contingency management. Adherence measurement components include self-reports, remote direct visualization, fully automated computer vision algorithms, biosensors, smart pill bottles, ingestible sensors, pill counts, and utilization measures. Intervention modalities include short messaging service, mobile phone apps, websites, and interactive voice response. We provide graphical representations of intervention component categories and an element-wise breakdown of multicomponent interventions.

CONCLUSIONS

Many technology-based medication adherence and monitoring interventions have been studied across psychiatric disease contexts. Interventions that are useful in one psychiatric disorder may be useful in other disorders, and further research is necessary to elucidate the specific effects of individual intervention components. Our framework is directly developed from the substance use disorder and mental health treatment literature and allows for transdiagnostic comparisons and an organized conceptual mapping of interventions.

Associations Among Depressive Symptoms, Wellness, Patient Involvement, Provider Cultural Competency, and Treatment Nonadherence: A Pilot Study Among Community Patients Seen at a University Medical Center

Treatment nonadherence is a pernicious problem associated with increasing rates of chronic diseases, escalating healthcare costs, and rising mortality in some patients. Although researchers have suggested numerous factors related to treatment nonadherence, several understudied aspects warrant attention, such as primary-care settings, provider cultural competence, and patient involvement. Adding to the research base, the present pilot study examined 88 primarily Black American and White American community patients from a large university medical center in the southern part of the United States. The study explored two research questions: (a) To what extent are there associations among depressive symptoms, wellness, patient involvement, cultural competency, and treatment nonadherence in a racially diverse community patient population? And (b) to what extent do the study exploratory variables and background characteristics predict treatment nonadherence, both separately and jointly? Depressive symptoms, the patient's perception of a provider's cultural competence, and marital/partnered status were found to be statistically significantly associated with treatment nonadherence, but not entirely in the directions expected.

The Reduction of Public and Internalized Stigma in Late-Life Depression: A Pilot Study

Innovative strategies are needed to reduce the impact of stigma as a barrier to mental health services for older adults living with a mental illness. The purpose of this brief report was to examine the impact of a 3-month peer educator (PE) intervention on stigma reduction in a sample of depressed older adults. PEs are individuals of similar age, and racial and socioeconomic backgrounds who have been previously treated for depression, and are trained to provide support and education to depressed individuals within their community. Participants (N = 21) aged 60 and older completed a demographic questionnaire, public stigma, and internalized stigma measures pre- and post-PE intervention. The results of paired samples t tests indicated that the use of PEs significantly reduced both public and internalized stigma among depressed older adults. PEs may be an effective strategy toward alleviating stigma and increasing mental health service utilization among older adults with depression.

Prevalence and predictors of sub-optimal medication adherence among patients with severe mental illnesses in a tertiary psychiatric facility in Maiduguri, North-eastern Nigeria

Introduction

Sub-optimal adherence constitutes a significant impediment to the management of severe mental illnesses (SMIs) as it negatively impacts on the course of the illness and the treatment outcome. In this study, the levels of adherence, prevalence and the predictors of sub-optimal adherence were assessed in a sub-Saharan African setting.

Methods

Three hundred and seventy (370) respondents with diagnoses of schizophrenia, bipolar disorder or severe depression were randomly enrolled and interviewed at the out-patient department of the Federal Neuropsychiatric Hospital, Maiduguri in northeastern Nigeria. An anonymous sociodemographic questionnaire and a clinical proforma designed by the authors, Oslo social support scale and the 8-item Morisky Medication Adherence Scale (MMAS-8) were used for data collection.

Results

The prevalence of sub-optimal adherence was 55.7%. The independent predictors of sub-optimal adherence were; seeking for traditional/ spiritual treatment (Odds Ratio (O.R.) = 6.523, 95% C.I. = 3.773 - 11.279, P = < 0.001), male gender (O.R. = 3.307, 95% C.I. = 1.907 - 5.737, P = < 0.001), low levels of insight (O.R. = 1.753, 95 C.I. = 1.220 - 2.519, P = 0.002), and low social support levels (O.R. = 1.528, 95% C.I. = 1.097 - 2.129, P = 0.012).

Conclusion

Based on the outcome of the study, we recommend the development of psycho-educational programmes on adherence and the active involvement of the relations and significant others in the management of patients with SMIs in sub-Saharan Africa.
