Unmet needs and research challenges for late-life mood disorders

Effectiveness of the Program to Encourage Active, Rewarding Lives (PEARLS) to reduce depression: a multi-state evaluation

Introduction

An estimated 15% of community-dwelling older adults have depressive symptoms in the U.S. The Program to Encourage Active, Rewarding Lives (PEARLS) is an evidence-based program for managing late-life depression. PEARLS is a home/community-based collaborative care model delivered by community-based organizations to improve access to quality depression care. Trained staff actively screen for depression to improve recognition, teach problem-solving and activity planning skills for self-management, and connect participants to other supports and services as needed.

Methods

This study examined 2015-2021 data from 1,155 PEARLS participants across four states to assess PEARLS effectiveness to reduce depressive symptoms. The clinical outcomes were measured by the self-reported PHQ-9 instrument to assess changes in depressive symptoms scored as depression-related severity, clinical remission, and clinical response. A generalized estimating equation (GEE) model was fitted to examine changes in composite PHQ-9 scores from baseline to the final session. The model adjusted for participants' age, gender, race/ethnicity, education level, income level, marital status, number of chronic conditions, and number of PEARLS sessions attended. Cox proportional hazards regression models were conducted to estimate the hazard ratio for improvement of depressive symptoms (i.e., remission or response), while adjusting for the covariates.

Results

PHQ-9 scale scores significantly improved from baseline to their final sessions (mean difference = -5.67, SEM = 0.16, p < 0.001). About 35% of participants achieved remission with PHQ-9 score < 5. Compared to participants with mild depression, patients with moderate depression (HR = 0.43, 95%CI = 0.35-0.55), moderately severe depression (HR = 0.28, 95%CI = 0.21-0.38), and severe depression (HR = 0.22 95%CI = 0.14-0.34) were less likely to experience clinical remission with PHQ-9 score < 5, while adjusting for the covariates. About 73% achieved remission based on no longer having one or both cardinal symptoms. Compared to participants with mild depression, patients with moderate depression (HR = 0.66, 95%CI = 0.56-0.78), moderately severe depression (HR = 0.46, 95%CI = 0.38-0.56), and severe depression (HR = 0.38, 95%CI = 0.29-0.51) were less likely to experience clinical remission, while adjusting for the covariates. Nearly 49% of participants had a clinical response or a ≥ 50% decrease in PHQ-9 scores over time. There were no differences between the severity of depression groups based on the time to clinical response.

Discussion

Findings confirm that PEARLS is an effective program to improve depressive symptoms among older adults in diverse real-world community settings and can be a more accessible option for depressive older adults who are traditionally underserved by clinical care.

Guided Self-Help Behavioral Activation Intervention for Geriatric Depression: Protocol for Pilot Randomized Controlled Trial

Background

Aging is a social concern. The increased incidence of depression in older populations in China poses a challenge to the health care system. Older adults who are depressed often suffer from a lack of motivation. Behavioral activation treatment, an evidence-based guided self-help treatment, is effective in reducing anhedonia and amotivation in depression; however, the efficacy of guided self-help behavioral activation in older adults with depression is not yet known.

Objective

The aim of this study is to pilot a self-help guided intervention for the treatment of depression in older adults.

Methods

This study has been designed as a pilot randomized controlled trial with inpatients (n=60; to be randomly allocated 1:1) between the ages of 60 and 70 and who have major depressive disorder. Patients attending clinical psychological clinics at the Mental Health Center of Chongqing will be randomized to either receive guided self-help behavioral activation (intervention) or to be on a 6-week waiting list (control). Participants in the treatment group will receive 6 sessions of guided self-help behavioral activation delivered over the telephone. The waiting list control group will receive the intervention after a period of 6 weeks. Exclusion criteria will be individuals who are at significant risk of harming themselves or others, who have a primary mental health disorder other than depression, or who have an intellectual disability that would hamper their ability to participate in the intervention. Effects of the treatment will be observed using outcomes in 3 domains: (1) clinical outcomes (symptom severity, recovery rate), (2) process variables (patient satisfaction, attendance, dropout), and (3) economic outcomes (cost and resource use). We will also examine mediators of outcomes in terms of patient variables (behavioral activation or inhibition motivation). We hypothesize that guided self-help behavioral activation will have a beneficial effect.

Results

The study was approved by the research ethics committee of the Mental Health Center of Chongqing in November 2019. As of July 2020, recruitment had not yet begun. Data collection is expected to be completed by December 2020. Data analysis is expected to be completed by June 2021. Results will then be disseminated to patients, to the public, to clinicians, and to researchers through publications in journals and presentations at conferences.

Conclusions

This will be the first study in China to investigate guided self-help interventions for patients who are older adults and who are depressed, a group which is currently underrepresented in mental health research. The intervention is modular and adapted from an empirically supported behavioral activation treatment for depression. The generalizability and broad inclusion criteria are strengths.

Unmet need for social care among older people

Understanding the nature and extent of unmet need for social care among older people is a critical policy priority in the United Kingdom and beyond, as national governments juggle the provision of adequate social care for a growing older population with competing funding priorities. Several factors can heighten the experience of unmet need among older people, for instance their family environment, and their health and socio-economic status. This paper contributes empirical evidence on the patterns of unmet need for social care among older people in England today, focusing on the individual characteristics associated with experiencing unmet need in relation to mobility tasks, activities of daily living (ADLs) and instrumental activities of daily living (IADLs). The results show that about 55 per cent of older individuals with an ADL difficulty had unmet need, compared to 24 per cent of those with an IADL difficulty and 80 per cent of those with a mobility difficulty. Characteristics reflecting greater vulnerability were more strongly associated with the risk of experiencing unmet need for ADLs, and such vulnerability was greater for particular ADLs (e.g. bathing), and for a higher number of ADLs. The findings reaffirm the complexity of conceptualising and empirically investigating unmet need in later life, and add to our understanding of the challenges of providing adequate and appropriate social care to older people.

The impact of depressive symptoms on utilization of home care by the elderly: Longitudinal results from the AgeMooDe study

BACKGROUND

Depression is the most common psychiatric disease in older people, often accompanied by co-morbidities and functional limitations. In cross-sectional studies, depression is associated with an increased use of health care resources, including informal care and home care. Longitudinal data are needed to better understand the causal links between depression, functional impairments, and health care utilization.

METHODS

Data were obtained at baseline and follow-up of the multicenter, prospective cohort study "Late life depression in primary care: needs, health care utilization and costs" (AgeMooDe). A sample of 955 primary care patients aged 75 years and older was interviewed twice. The primary outcomes were the average respective amounts of time spent utilizing home care, professional nursing care, domestic help and informal care. These outcomes were analyzed with Generalized Linear Mixed Models (GLMM).

RESULTS

GLMM analysis revealed that the amount of time utilizing home care over the study period was positively associated with depression, higher age, and functional and cognitive impairments, but negatively associated with living alone. In-depth analyses revealed that these associations were particularly obvious for the utilization of informal care.

LIMITATIONS

The generalizability of our findings may be limited due to use of a dimensional instrument to determine depressive symptoms.

CONCLUSIONS

Over the study period, the average amount of time receiving home care and especially informal care increased in the group of patients with depression only. People with depressive symptoms experience a growing number of functional limitations over time, increasing their dependency on others. Functional limitations, depression and dependency appear to form a vicious cycle.

Asthma, COPD and comorbidities in elderly people

Co-morbidities are a significant problem in the elderly population but are rarely presented and analyzed for interdependencies among the various coexisting chronic diseases.

OBJECTIVE

The aim of this study was to present a profile of comorbidities in elderly patients with and without asthma and COPD.

METHODS

Respondents were recruited at 20 sites in Poland. Stratified random sampling from patient databases resulted in 15,973 patients older than 60 years of age. A retrospective analysis of medical history and ICD-10 codes was performed. In addition, patients underwent a spirometry test with a bronchial reversibility test and were administered questionnaires on the prevalence of chronic diseases by doctors.

RESULTS

The study population consisted of 1023 asthmatic patients, 1084 patients with COPD and 1076 control subjects without any signs of bronchoconstriction and with correct spirometry. Patients with asthma exhibited a similar distribution of cardiovascular and metabolic co-morbidities as the control group. However, asthmatic patients had a higher prevalence of arterial hypertension and depression with an odds ratio (OR) = 1.48 (95% CI: 1.38-1.62) and OR = 1.52 (95% CI: 1.44-1.68), respectively. Coronary disease (OR = 2.12; 95% CI: 1.97-2.33), cor pulmonale (OR = 3.1; 95% CI: 2.87-3.22) and heart failure (OR = 2.71; 95% CI: 2.64-3.11) were predominantly observed in patients with COPD. Patients with severe asthma exhibited a greater predisposition to cardiovascular and neuropsychiatric diseases.

CONCLUSION

Asthma coexisted frequently with arterial hypertension and depression in elderly patients. Patients with COPD have a more exaggerated profile of coexisting diseases, specifically cardiovascular problems.
