Strategies to improve anxiety and depression in patients with COPD: a mental health perspective

A tailored psychological intervention for anxiety and depression management in people with chronic obstructive pulmonary disease: TANDEM RCT and process evaluation

Background

People with chronic obstructive pulmonary disease have high levels of anxiety and depression, which is associated with increased morbidity and poor uptake of effective treatments, such as pulmonary rehabilitation. Cognitive-behavioural therapy improves mental health of people with long-term conditions and could potentially increase uptake of pulmonary rehabilitation, enabling synergies that could enhance the mental health of people with chronic obstructive pulmonary disease.

Aim

Our aim was to develop and evaluate the clinical effectiveness and cost effectiveness of a tailored cognitive-behavioural approach intervention, which links into, and optimises the benefits of, routine pulmonary rehabilitation.

Design

We carried out a pragmatic multicentre randomised controlled trial using a 1.25 : 1 ratio (intervention : control) with a parallel process evaluation, including assessment of fidelity.

Setting

Twelve NHS trusts and five Clinical Commissioning Groups in England were recruited into the study. The intervention was delivered in participant's own home or at a local NHS facility, and by telephone.

Participants

Between July 2017 and March 2020 we recruited adults with moderate/very severe chronic obstructive pulmonary disease and mild/moderate anxiety and/or depression, meeting eligibility criteria for assessment for pulmonary rehabilitation. Carers of participants were invited to participate.

Intervention

The cognitive-behavioural approach intervention (i.e. six to eight 40- to 60-minute sessions plus telephone support throughout pulmonary rehabilitation) was delivered by 31 trained respiratory healthcare professionals to participants prior to commencing pulmonary rehabilitation. Usual care included routine pulmonary rehabilitation referral.

Main outcome measures

Co-primary outcomes were Hospital Anxiety and Depression Scale - anxiety and Hospital Anxiety and Depression Scale - depression at 6 months post randomisation. Secondary outcomes at 6 and 12 months included health-related quality of life, smoking status, uptake of pulmonary rehabilitation and healthcare use.

Results

We analysed results from 423 randomised participants (intervention, n = 242; control, n = 181). Forty-three carers participated. Follow-up at 6 and 12 months was 93% and 82%, respectively. Despite good fidelity for intervention delivery, mean between-group differences in Hospital Anxiety and Depression Scale at 6 months ruled out clinically important effects (Hospital Anxiety and Depression Scale - anxiety mean difference -0.60, 95% confidence interval -1.40 to 0.21; Hospital Anxiety and Depression Scale - depression mean difference -0.66, 95% confidence interval -1.39 to 0.07), with similar results at 12 months. There were no between-group differences in any of the secondary outcomes. Sensitivity analyses did not alter these conclusions. More adverse events were reported for intervention participants than for control participants, but none related to the trial. The intervention did not generate quality-of-life improvements to justify the additional cost (adjusted mean difference £770.24, 95% confidence interval -£27.91 to £1568.39) to the NHS. The intervention was well received and many participants described positive affects on their quality of life. Facilitators highlighted the complexity of participants' lives and considered the intervention to be of potential valuable; however, the intervention would be difficult to integrate within routine clinical services. Our well-powered trial delivered a theoretically designed intervention with good fidelity. The respiratory-experienced facilitators were trained to deliver a low-intensity cognitive-behavioural approach intervention, but high-intensity cognitive-behavioural therapy might have been more effective. Our broad inclusion criteria specified objectively assessed anxiety and/or depression, but participants were likely to favour talking therapies. Randomisation was concealed and blinding of outcome assessment was breached in only 15 participants.

Conclusions

The tailored cognitive-behavioural approach intervention delivered with fidelity by trained respiratory healthcare professionals to people with chronic obstructive pulmonary disease was neither clinically effective nor cost-effective. Alternative approaches that are integrated with routine long-term condition care are needed to address the unmet, complex clinical and psychosocial needs of this group of patients.

Effectiveness of Paced Breathing Guided by Biofeedback on Clinical and Functional Outcomes Patients with Chronic Obstructive Pulmonary Disease: An Uncontrolled Pilot Study

To investigate the effectiveness of paced breathing guided by biofeedback on clinical and functional outcomes of patients with chronic obstructive pulmonary disease (COPD). An uncontrolled pilot study comprising a training with paced breathing guided by biofeedback (three sessions of 35 min per week) was conducted over four weeks (12 sessions). Assessments included respiratory muscle strength (using a manovacuometer), anxiety (Beck Anxiety Inventory), depression (Beck Depression Inventory), dyspnea (Baseline Dyspnea Index), functionality (Timed Up and Go Test), health status (COPD Assessment Test) and health-related quality of life (Saint George's Respiratory Questionnaire). The sample consisted of nine patients with a mean age of 68.2 ± 7.8 years. After intervention, patients significantly improved in health status and health-related quality of life, assessed using the COPD Assessment Test (p < 0.001) and Saint George's Respiratory Questionnaire (p < 0.001); anxiety (p < 0.001); and depression (p = 0.001). Patients also significantly improved in dyspnea (p = 0.008), TUG (p = 0.015), CC Score (p = 0.031), and maximum inspiratory (p = 0.004) and expiratory pressures (p < 0.001). An intervention with paced breathing guided by biofeedback promoted positive results on dyspnea, anxiety, depression, health status and perceived health-related quality of life in patients with COPD. Moreover, gains in respiratory muscle strength and functional performance were observed, affecting the performance of daily activities.

Tailored psychological intervention for anxiety or depression in COPD (TANDEM): a randomised controlled trial

BACKGROUND

The TANDEM multicentre, pragmatic, randomised controlled trial evaluated whether a tailored psychological intervention based on a cognitive behavioural approach for people with COPD and symptoms of anxiety and/or depression improved anxiety or depression compared with usual care (control).

METHODS

People with COPD and moderate to very severe airways obstruction and Hospital Anxiety and Depression Scale subscale scores indicating mild to moderate anxiety (HADS-A) and/or depression (HADS-D) were randomised 1.25:1 (242 intervention and 181 control). Respiratory health professionals delivered the intervention face-to-face over 6-8 weeks. Co-primary outcomes were HADS-A and HADS-D measured 6 months post-randomisation. Secondary outcomes at 6 and 12 months included: HADS-A and HADS-D (12 months), Beck Depression Inventory II, Beck Anxiety Inventory, St George's Respiratory Questionnaire, social engagement, the EuroQol instrument five-level version (EQ-5D-5L), smoking status, completion of pulmonary rehabilitation, and health and social care resource use.

RESULTS

The intervention did not improve anxiety (HADS-A mean difference -0.60, 95% CI -1.40-0.21) or depression (HADS-D mean difference -0.66, 95% CI -1.39-0.07) at 6 months. The intervention did not improve any secondary outcomes at either time-point, nor did it influence completion of pulmonary rehabilitation or healthcare resource use. Deaths in the intervention arm (13/242; 5%) exceeded those in the control arm (3/181; 2%), but none were associated with the intervention. Health economic analysis found the intervention highly unlikely to be cost-effective.

CONCLUSION

This trial has shown, beyond reasonable doubt, that this cognitive behavioural intervention delivered by trained and supervised respiratory health professionals does not improve psychological comorbidity in people with advanced COPD and depression or anxiety.

Associations of self-reported chronic obstructive pulmonary disease with indicators of economic instability and stress - 16 states, 2017

OBJECTIVES

To examine the association between chronic obstructive pulmonary disease status and indicators of economic instability and stress to better understand the magnitude of these issues in persons with chronic obstructive pulmonary disease.

METHODS

Analyzed 2017 Behavioral Risk Factor Surveillance System data from 16 states that administered the 'Social Determinants of Health' module, which included economic instability and stress measures (N = 101,461). Associations between self-reported doctor-diagnosed chronic obstructive pulmonary disease status and each measure were examined using multinomial logistic models.

RESULTS

Adults with chronic obstructive pulmonary disease were more likely (p < 0.001) than adults without to report not having enough money at month end (21.0% vs. 7.9%) or just enough money (44.9% vs. 37.2%); being unable to pay mortgage, rent, or utility bills (19.2% vs. 8.8%); and that often or sometimes food did not last or could not afford to eat balanced meals (37.9% vs. 20.6%), as well as stress all or most of the time (27.3% vs. 11.6%). Associations were attenuated although remained significant after adjustments for sociodemographic and health characteristics.

DISCUSSION

Financial, housing, and food insecurity and frequent stress were more prevalent in adults with chronic obstructive pulmonary disease than without. Findings highlight the importance of including strategies to address challenges related to economic instability and stress in chronic obstructive pulmonary disease management programs.

Anxiety and Depressive Symptoms in Patients with COPD: Modifiable Explanatory Factors

Anxiety and depressive symptoms affect up to 80% of people with chronic obstructive pulmonary disease (COPD). To reduce this symptom burden, clinicians should target modifiable explanatory factors while accounting for nonmodifiable explanatory factors of these symptoms. The purpose of this secondary data analysis was to examine which modifiable factors explain anxiety and depressive symptoms in COPD. This secondary data analysis of 1,760 COPD patients used multiple regression to explain anxiety and depressive symptoms from sets of modifiable patient characteristics and demographic controls. Clinically significant symptoms of anxiety or depression presented in 29.6% (n = 526) of participants, and 20.6% (n = 363) had both. Significant modifiable explanatory factors of both disorder symptoms were perceived functional status, functional capacity, psychosocial impact, symptom self-management, and significant symptoms for the other. Somatic symptom burden and dyspnea explained anxiety and depressive symptoms, respectively. Addressing these modifiable factors may reduce anxiety and depressive symptoms in patients with COPD.

Cigarette smoke-induced pulmonary impairment is associated with social recognition memory impairments and alterations in microglial profiles within the suprachiasmatic nucleus of the hypothalamus

Chronic obstructive pulmonary disease (COPD) is a major, incurable respiratory condition that is primarily caused by cigarette smoking (CS). Neurocognitive disorders including cognitive dysfunction, anxiety and depression are highly prevalent in people with COPD. It is understood that increased lung inflammation and oxidative stress from CS exposure may 'spill over' into the systemic circulation to promote the onset of these extra-pulmonary comorbidities, and thus impacts the quality of life of people with COPD. The precise role of the 'spill-over' of inflammation and oxidative stress in the onset of COPD-related neurocognitive disorders are unclear. The present study investigated the impact of chronic CS exposure on anxiety-like behaviors and social recognition memory, with a particular focus on the role of the 'spill-over' of inflammation and oxidative stress from the lungs. Adult male BALB/c mice were exposed to either room air (sham) or CS (9 cigarettes per day, 5 days a week) for 24 weeks and were either daily co-administered with the NOX2 inhibitor, apocynin (5 mg/kg, in 0.01 % DMSO diluted in saline, i.p.) or vehicle (0.01 % DMSO in saline) one hour before the initial CS exposure of the day. After 23 weeks, mice underwent behavioral testing and physiological diurnal rhythms were assessed by monitoring diurnal regulation profiles. Lungs were collected and assessed for hallmark features of COPD. Consistent with its anti-inflammatory and oxidative stress properties, apocynin treatment partially lessened lung inflammation and lung function decline in CS mice. CS-exposed mice displayed marked anxiety-like behavior and impairments in social recognition memory compared to sham mice, which was prevented by apocynin treatment. Apocynin was unable to restore the decreased Bmal1-positive cells, key in cells in diurnal regulation, in the suprachiasmatic nucleus of the hypothalamus to that of sham levels. CS-exposed mice treated with apocynin was associated with a restoration of microglial area per cell and basal serum corticosterone. This data suggests that we were able to model the CS-induced social recognition memory impairments seen in humans with COPD. The preventative effects of apocynin on memory impairments may be via a microglial dependent mechanism.

Association Among Chronic Obstructive Pulmonary Disease Severity, Exacerbation Risk, and Anxiety and Depression Symptoms in the SPIROMICS Cohort

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is a common, progressive lung disease that often manifests with psychiatric symptoms. Despite this, patients with COPD are not routinely screened for anxiety and depression, which substantially contribute to COPD-related morbidity.

OBJECTIVE

To determine the relationship among COPD symptom severity, exacerbation risk, and clinically significant anxiety and depression symptoms in ever smokers with COPD.

METHODS

We used baseline data from the Subpopulations and Intermediate Outcome Measures In COPD Study (SPIROMICS) cohort to examine ever smokers with COPD across Global Initiative for Obstructive Lung Disease (GOLD) disease severity groups. Multivariable logistic regression models were used to calculate odds ratios for clinically significant anxiety and depression for each GOLD group, which was compared to the control group of ever smokers without COPD. Odds ratios were adjusted for subject demographics, medical comorbidities, and substance use covariates, and comparisons were completed using 2-tailed tests.

RESULTS

Of the 2664 subjects studied, 784 (29.4%) had clinically significant anxiety, and 497 (18.7%) had clinically significant depression. In the multivariable analysis, high pulmonary symptom groups, groups B and D, had increased adjusted odds of clinically significant anxiety (group B: adjusted odds ratios [AOR] 1.28, P = 0.03; group D: AOR 1.95, P < 0.0001) and depression (group B: AOR 2.09, P < 0.0001; group D: AOR 3.04, P < 0.0001). GOLD group D, the group with high pulmonary symptoms and high COPD exacerbation risk, had the greatest risk of both anxiety and depression among the GOLD groups.

CONCLUSIONS

High COPD symptom severity, even in the absence of elevated COPD exacerbation risk, is associated with clinically significant anxiety and depression. Our separate analyses of anxiety and depression symptoms in a large, multisite, national cohort are unique within the literature and have important treatment implications for COPD patients. Our findings also highlight the utility of screening patients with high COPD symptom severity for anxiety and depression.

A qualitative study of the sources of chronic obstructive pulmonary disease-related emotional distress

OBJECTIVE

The aim of this study is to identify the sources of illness-related emotional distress from the perspective of individuals living with mild to severe chronic obstructive pulmonary disease (COPD).

METHODS

A qualitative study design with purposive sampling was applied at a Swiss University Hospital. Eleven interviews were conducted with individuals who suffered from COPD. To analyze data, framework analysis was used, guided by the recently presented model of illness-related emotional distress.

RESULTS

Six main sources for COPD-related emotional distress were identified: physical symptoms, treatment, restricted mobility, restricted social participation, unpredictability of disease course and COPD as stigmatizing disease. Additionally, life events, multimorbidity and living situation were found to be sources of non-COPD-related distress. Negative emotions ranged from anger, sadness, and frustration to desperation giving rise to the desire to die. Although most patients experience emotional distress regardless of the severity of COPD, the sources of distress appear to have an individual manifestation.

DISCUSSION

There is a need for a careful assessment of emotional distress among patients with COPD at all stages of the disease to provide patient-tailored interventions.

Nortriptyline Modulates the Migration of Peripheral Blood Lymphocytes and Monocytes in Patients with Chronic Obstructive Pulmonary Disease

In the present study, the effect of nortriptyline (1 and 10 μM), budesonide (10 nM) and their combination on the migration of peripheral blood lymphocytes and monocytes from patients with chronic obstructive pulmonary disease (COPD) towards chemokines CCL5 and CXCL10 was evaluated by flow cytometry. Nortriptyline (10 μM), both alone and in combination with budesonide, inhibited the migration of T helper cells, cytotoxic T lymphocytes, NK cells and B lymphocytes towards CCL5 and CXCL10, as well as enhanced monocyte migration towards these chemokines. The combination of nortriptyline (1 μM) and budesonide suppressed the chemotaxis of lymphocyte subpopulations towards CXCL10, but not towards CCL5, more effectively than budesonide alone. The combination of nortriptyline (10 μM) and budesonide inhibited the migration of lymphocyte subpopulations towards CCL5 and CXCL10 and activated monocyte chemotaxis towards both chemokines more effectively than budesonide alone. The results of this study demonstrate the ability of nortriptyline alone to modulate the migration of peripheral blood lymphocytes and monocytes from patients with COPD and to potentiate the effects of budesonide.

Exploring the Necessity of Psychological Rounds and Psychological Interventions in General Hospitals in the Post-COVID-19 Period

Objective

To explore the necessity of psychological rounds and psychological intervention in the post-COVID-19 period in a general hospital.

Methods

Based on the current pandemic influence on Chinese people's psychology, the medical experience, and environment were analyzed, and the feasibility of psychological evaluation and intervention were appraised with the psychological changes that might be brought by the medical behaviors, especially for surgical operations.

Results

Nowadays, the pandemic is under full control in China, although the pandemic is rampant abroad. In China, the "Normalized pandemic prevention" phase has begun. In the post-COVID-19 period, the prolonged pandemic has made numerous people pessimistic, angry, and other negative emotions. Several general hospitals are facing huge influences: under the influence of anxiety, such as "higher hospital-acquired infection rate," the patient attendance rate is reduced, and the hospital income is sharply reduced. Doctor-patient conflicts are more likely to occur during the medical procedures, affecting the medical experience, and reducing the rate of re-visit and referral.

Conclusion

After analyzing a series of "endogenous" and "exogenous" factors of medical procedures in a general hospital in the post-pandemic period, it suggests that anxiety and depression caused by uncertainties in the medical procedures may be more obvious. Also, it is necessary to pay attention to the psychological status of patients and carry out psychological rounds and psychological interventions in general hospitals. The service quality can be improved, the medical experience can be ameliorated, and it can help general hospitals to turn "crisis" into "opportunity," which also brings better development.

Anxiety and Depression in Chronic Obstructive Pulmonary Disease: Perspectives on the Use of Hypnosis

Chronic Obstructive Pulmonary Disease (COPD) is a highly prevalent and debilitating respiratory condition, characterized by chronic airflow limitation, breathlessness, and other persistent respiratory symptoms. Critically, patients suffering from COPD often find themselves trapped in a vicious comorbidity cycle: while breathlessness and increased respiratory rate are known inducers of anxiety, the latter have been shown in turn to exacerbate breathlessness and chest discomfort. Hypnosis holds great potential for the simultaneous complementary management of anxiety and breathlessness in COPD. It is an inexpensive psychological intervention tailored to the patient's own experience, convenient in terms of logistics and implementation. In this short qualitative review, we present hypnosis' structural, cognitive, and neural fundamentals, and assess existing instances of hypnosis use in the treatment of anxiety, depression, and respiratory disease. We then discuss its potential as a tool for improving health-related quality of life and the self-management of COPD within (and beyond) pulmonary rehabilitation.

Frequency and Associated Factors of Suicidal Ideation in Patients with Chronic Obstructive Pulmonary Disease

We aimed to examine the prevalence of suicidal ideation in patients with chronic obstructive pulmonary disease (COPD) and the association between demographic and clinical variables and the occurrence of suicidal thoughts. This was a cross-sectional study. Sociodemographic and clinical data were recorded, and questionnaires were used to assess depressive symptoms (Beck Depression Inventory), comorbidities (Charlson Index), cognitive performance (Mini Mental State Examination), and quality of life (EuroQoL-5 dimensions and CAT). Specific questions about suicide-related behavior were included. Multivariate logistic regression analysis identified the significant factors associated with previous suicidal ideation and suicide attempts. The analysis included 1190 subjects. The prevalence of suicidal ideation and suicide attempts were 12.1% and 2.5%, respectively. Severely depressed patients had the highest prevalence of suicide-related behavior. The adjusted logistic model identified factors significantly associated with suicidal ideation: sex (odds ratio (OR) for women vs. men = 2.722 (95% confidence interval (CI) = 1.771–4.183)), depression score (OR = 1.163 (95% IC = 1.127–1.200)), and Charlson Index (OR 1.228 (95% IC 1.082–1.394)). Suicidal ideation is common in COPD patients, especially in women. While addressing suicidal ideation and suicide prevention, clinicians should first consider the management of depressive symptomatology and the improvement of coping strategies.

Benefit-Risk Assessment of Psychotropic Drugs in Older Patients with Chronic Obstructive Pulmonary Disease

Depression, anxiety, and other mental health disorders, including bipolar disorder and schizophrenia, occur commonly in older adults with chronic obstructive pulmonary disease (COPD), and they are often inadequately treated. We review the available evidence for benefits and risks of pharmacologic treatments (e.g. selective serotonin reuptake inhibitors [SSRIs], serotonin-noradrenaline reuptake inhibitors [SNRIs], tricyclic antidepressants [TCAs], antipsychotic drugs, and benzodiazepines) for common mental illnesses in older persons with COPD. Evidence to use both SSRIs/SNRIs and TCAs from randomized controlled trials is uncertain for treating major depression in patients with COPD. However, population-based findings indicate that they are widely used, and this valuable intervention (preferably SSRIs/SNRIs) should not be denied for selected patients after evaluating potential risks and benefits, especially patients presenting with major depression and suicidal ideation, when a collaborative-care approach is being used. Although there is some evidence for the short-term use of benzodiazepines for treating insomnia, breathlessness, and anxiety in patients with COPD, their long-term use should be closely monitored or avoided to reduce the increased rate of major adverse events. Currently, there are only limited data on the use of antipsychotic drugs for managing schizophrenia or bipolar disorder in older patients with COPD. Hence, clinicians should use extra caution when prescribing antipsychotic agents and be vigilant for symptoms of acute respiratory failure and other adverse effects. Psychotropic medications are clearly beneficial for younger, healthy persons with depression and anxiety; however, the risk-benefit calculation is not so clear for treating psychological problems, schizophrenia, and bipolar disorder in older adults with COPD, given older-adult sensitivity to medications and the mixed findings of relatively few controlled trials.

Nortriptyline overcomes corticosteroid resistance in NK and NKT-like cells from peripheral blood of patients with chronic obstructive pulmonary disease

Introduction: An antidepressant nortriptyline potentiates glucocorticoid (GC) action with synergistic suppression of inflammatory mediator release, but the precise molecular mechanism is unknown.

Materials and methods: Peripheral blood cells from patients with chronic obstructive pulmonary disease (COPD) (n = 21) were incubated with nortriptyline (1 µM or 10 µM), budesonide (10 nM), or their combinations, followed by stimulation with phorbol myristate acetate (PMA) and ionomycin. Cytokine production, glucocorticoid receptor β (GRβ), histone deacetylase 2 (HDAC2) and histone H4 acetylation of K8 (HAT) expression, p65 NF-kB and p38 mitogen-activated protein kinase (p38 MAPK) phosphorylation in NK (CD3-CD56+) and NKT-like (CD3+CD56+) cells were analyzed by flow cytometry.

Results: We observed that nortriptyline (10 µM) significantly attenuated the effects of PMA/ionomycin on the synthesis of interferon γ (IFNγ), interleukin 4 (IL-4), and IL-8, expression of GRβ and HAT, as well as p65 NF-kB and p38 MAPK phosphorylation in NK and NKT-like cells, whereas nortriptyline (1 µM) only inhibited IL-4 production by NK and NKT-like cells.

Discussion: The combination of nortriptyline (10 µM) and budesonide decreased IFNγ, tumor necrosis factor α, IL-4, IL-8, and GRβ expression, as well as phosphorylated p38 MAPK and p65 NF-κB levels by NK and NKT-like cells above that of budesonide alone. Furthermore, the same association of drugs enhanced HDAC2 expression in NK and NKT-like cells.

Conclusion: Collectively, our results show that nortriptyline might enhance GC function through modulation of HAT, HDAC2, GRβ, phospho-p38 MAPK expression. These data provide a strong rationale for combining nortriptyline with budesonide to treat COPD.

Anxiety and Depression in Patients With Idiopathic Subglottic Stenosis

OBJECTIVES

To characterize the presence and severity of anxiety and depression in patients with symptomatic idiopathic subglottic stenosis (ISGS). To determine the relationship between dyspnea severity and anxiety and depression symptom severity.

METHODS

Patients diagnosed with idiopathic subglottic stenosis and treated at Mayo Clinic Florida or Mayo Clinic Arizona retrospectively completed the PROMIS Depression, PROMIS Anxiety, PROMIS Dyspnea Functional Limitations, and Dyspnea Index questionnaires. Patients with dyspnea and without idiopathic subglottic stenosis were also asked to complete the questionnaires as a control group.

RESULTS

This explorative retrospective study includes 44 control patients and 46 ISGS patients. Unadjusted and adjusted group comparisons found no statistically significant difference in dyspnea index, depression, anxiety, nor dyspnea functional limitation scores. Relationships between dyspnea severity and anxiety and depression severity were significant and persistent in both groups. Anxiety and depression were positively correlated (r = 0.66). Dyspnea severity positively correlate with both anxiety and depression (anxiety r = 0.49, depression r = 0.32).

CONCLUSIONS

Patients with symptomatic idiopathic subglottic stenosis are not at an increased risk of having anxiety and depression when compared to other dyspneic patients. As dyspnea severity worsens, patients are more likely to experience anxiety and depression. These findings support the prior literature and suggest the presence of dyspnea may warrant appropriate psychological screening and treatment to optimize dyspneic patients' quality of life and symptom improvement.

Hypnosis for the Management of COPD-related anxiety and dyspnea in Pulmonary Rehabilitation - rationale and design for a cluster-randomised, active-control trial [HYPNOBPCO_2]

Complementary psychological care is recommended for COPD, as it significantly reduces anxiety and boosts the pulmonary rehabilitation efficacy. In a precedent trial (HYPNOBPCO_1, ISRCTN10029862), administering a single hypnosis session was linked to reduced anxiety and improved breathing mechanics in intermediate and advanced COPD patients. However, whether hypnosis could improve self-management of anxiety and dyspnoea in COPD during pulmonary rehabilitation is yet to be investigated.

This is the protocol for HYPNOBPCO_2, a 2-arm, cluster-randomised, statistician-blinded superiority monocentre trial (NCT04868357). Its aim is to assess the efficacy of hypnosis as a tool to manage anxiety and dyspnoea during a pulmonary rehabilitation programme (PRP). Clusters of COPD patients eligible for the conventional hospital-based PRP at the Centre Hospitalier de Bligny (CHB) will be randomised and evenly allocated into two parallel arms: “Hypnosis” (treatment) and “Relaxation” (active control). “Hypnosis” will consist of the CHB's conventional 4-week group PRP, supplemented by two educational sessions for teaching self-hypnosis. “Relaxation” will be identical, except standard relaxation exercises will be taught instead. Primary end-point will consist of assessing weekly changes in anxiety throughout the PRP, additional to total anxiety change after treatment completion. Anxiety will be determined by the six-item version of the State-Trait Anxiety Inventory (STAI-6). Secondary outcomes will include change in the 6-min walk test and the COPD assessment test (CAT). Further follow-up outcomes will include CAT and STAI-6 retests, re-hospitalisation rate, action plan use and persistence in self-hypnosis use, throughout the 12 weeks ensuing PRP completion.

Rationale for HYPNOBPCO_2 (NCT04868357), a trial investigating whether self-hypnosis (fast, low-cost, effortless) reliably improves breathlessness-related anxiety and breathing mechanics, during and after pulmonary rehabilitation in COPDhttps://bit.ly/3JF2vCW

Effects of expressive art therapy on health status of patients with chronic obstructive pulmonary disease: a community-based cluster randomized controlled trial

Background and objective:

This study was performed to investigate the effect of expressive art therapy (EAT) on the health status of patients with chronic obstructive pulmonary disease (COPD).

Methods:

This community-based cluster randomized controlled trial involved patients with COPD from 16 communities in China. Participants received either EAT plus usual care (UC) or UC only. General practitioners were trained in EAT before the intervention. The primary outcomes were depression and anxiety symptoms, measured with the Hospital Anxiety and Depression Scale (HADS) and expressed as the HADS score for depression or anxiety (HADS-D or HADS-A, respectively). The secondary outcomes were the quality of life and dyspnoea, measured with the COPD assessment test (CAT). Dyspnoea was assessed using the modified Medical Research Council (mMRC) dyspnoea scale. Lung function was expressed as the forced expiratory volume in 1 s as a percentage of the predicted value [FEV₁ (% pred)]. Outcome data were collected from all participants at baseline, 2 and 6 months.

Results:

In total, 360 participants with COPD and comorbid depression were included in the analysis with the control group of 181 receiving UC only and the intervention group of 179 receiving EAT plus UC. The EAT group showed significantly greater improvement in the HADS-D and HADS-A scores than the UC group at 2 months (p < 0.0001 and p < 0.001, respectively) and 6 months (p < 0.001 for both). The CAT and mMRC scores were significantly lower in the EAT group than in the UC group at 2 and 6 months (p < 0.001 for all). The FEV₁ (% pred) was significantly higher in the EAT group than in the UC group at 6 months (p < 0.01).

Conclusion:

General practitioners can deliver EAT interventions. EAT can effectively reduce anxiety and depression symptoms and dyspnoea, improve quality of life and improve the pulmonary function of patients with COPD.

Substance Use and Misuse among Adults with Chronic Obstructive Pulmonary Disease in the United States, 2015-2019: Prevalence, Association, and Moderation

BACKGROUND

Despite the advancements in chronic obstructive pulmonary disease (COPD) treatment, complications related to COPD exacerbation remain challenging. One associated factor is substance use/misuse among adults with COPD. Fewer studies, however, examined the prevalence and association between COPD and substance use and misuse. In addition, limited knowledge existed about the moderation effects of serious psychological distress and gender among adults with COPD and substance use/misuse. We aimed, therefore, to measure such prevalence, association, and moderation from nationally representative samples in the United States.

METHOD

Data were drawn from the 2015-2019 National Survey on Drug Use and Health. Weighted logistic regressions were used to measure the associations of last-month tobacco (cigarettes, cigars, pipe, and smokeless tobacco products), other licit and illicit substance use (alcohol, marijuana, cocaine, crack, heroin, hallucinogens, and inhalants), and substance misuse (pain relievers, tranquilizers, stimulants, and sedatives) among adults with COPD. Serious psychological distress and gender were tested as moderators in the association between COPD and substance use/misuse.

RESULTS

The findings revealed that adults with COPD [Weighted N = 53,115,718) revealed greater odds of cigarettes [adjusted odds ratio (aOR) = 2.48 (95%CI = 1.80-3.42)) and smokeless tobacco (aOR = 3.65 (95%CI = 1.75-7.65)). However, they were less likely to use alcohol (aOR = 0.61 (95%CI = 0.45-0.84)). Adults with COPD who had serious psychological distress were more likely to use pipe tobacco and alcohol; however, they were less likely to use hallucinogens and inhalants. Finally, males compared to females with COPD were less likely to use smokeless tobacco.

CONCLUSION

Adults with COPD in the United States were more likely to use tobacco products and less likely to use alcohol. In addition, serious psychological distress and gender were moderators in associations between COPD and substance use but not in substance misuse. Future studies should longitudinally assess the factors that may contribute to the initiation and progression of substance use and misuse among adults with COPD.

Questionnaire Survey-Based Quantitative Assessment of the Impact of Transitional Care on Self-Management of Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease

Methods

Clinical information of 78 COPD patients treated with TC (intervention group) or routine care (control group) in Shanghai Pulmonary Hospital during March 2019 and August 2020 was gathered. Patients were followed up for 3 months after discharge. The intervention group (n = 39) was subjected to a TC plan for 3 months to help patients and their family caregivers for self-management of COPD. TC was provided by specially trained nurses, and patients were supported by standardized tools. Nursing measures in the control group (n = 79) included transitional support for 30 d after hospital discharge. In this way, patients were guaranteed to follow discharge plans and transit to outpatient nursing. Patient's anxiety and depression symptoms, sleep quality, survival quality, mobility, and life quality at admission and after 3 months of discharge were assessed by Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, Quality of Life Scale Abbreviated Version, Activity of Daily Life Scale, St. George's Respiratory Questionnaire, and COPD Assessment Test.

Results

Except for anxiety and depression, patient's sleep quality, survival quality, mobility, and life quality in two groups were significantly improved. Moreover, average change of total CAT score during 3 months of intervention was -5.44, while that in the control group was -1.74 (p = 0.011). Improvement of survival quality of patients in the intervention group (p = 0.001) was markedly greater than that in the control group (p = 0.016).

Conclusion

Altogether, TC based on quantification by questionnaire survey is beneficial to COPD patient's life quality and self-management.

Relationship between Depression and Anxiety, Health Status and Lung Function in Patients with Alpha-1 Antitrypsin Deficiency

Alpha-1 Antitrypsin deficiency (AATD) is a genetic condition that can lead to Chronic Obstructive Pulmonary Disease. The burden of psychological disease, its impact and contributing factors in patients with AATD are largely unknown. This study determined the prevalence of depression and anxiety in AATD and its clinical impact. All subjects with PiZZ/PiZnull (n = 635) and PiSZ (n = 111) genotypes within the AATD registry who had sufficient data to calculate pulmonary physiological and health status (HS) decline were grouped as those with or without a diagnosis of depression and/or anxiety. Univariate and multivariate analyses were performed on physiological, demographic and HS parameters. Depression and/or anxiety was present in 16.4% overall in both PiSZ and PiZZ/PiZnull cohorts and was associated with lower baseline pulmonary function and worse HS. In the multivariable analysis of the PiZZ/PiZnull cohort, a greater average decline in FEV₁% predicted was observed in those with depression and/or anxiety than those without (-1.53 SD ± 2.26 per year, -0.99 ± 1.79, respectively; p = 0.03) but there was no difference in HS decline (p = 0.33). No differences were seen in the PiSZ cohort. Dyspnoea (mMRC score) was generally worse in those with depression and/or anxiety than those without. Comorbidity burden did not differ between those with or without depression and/or anxiety. Disease severity and progression may be contributing to the prevalence of psychological factors in PiZZ/PiZnull patients. Patients who are declining rapidly should be actively monitored for psychological co-morbidity and treated by cognitive or pharmacological means.Supplemental data for this article is available online at https://doi.org/10.1080/15412555.2021.1991904 .

Racial Disparities in Health Risk Indicators Reported by Alabamians Diagnosed with COPD

Chronic Obstructive Pulmonary Disease (COPD) is a growing public health problem in the southern United States, particularly in Alabama. However, very little is known about specific health risk factors disproportionately impacting Alabamians with COPD. We conducted a latent class analysis of 2015–2019 Behavioral Risk Factor Surveillance System data from 4057 Alabamians with COPD (White = 2947, Black = 873, Other = 237). Eighteen risk indicators were examined across three health-related domains: (1) comorbidities, (2) limited healthcare access, and (3) substance use/abuse. Racial disparities between Black and white Alabamians with COPD were assessed using configural similarity analysis. Findings showed that almost one-third (31%) of Alabamians with COPD were in the high-risk class for eight comorbidities, and nearly one-half (48.88%) belonged to the high-risk class for limited healthcare access. Black Alabamians with COPD who did not have health insurance were much more likely to be at high risk for limited healthcare access (94.44%) when compared to their counterparts with insurance (5.56%), χ²(df = 2) = 1389.94, p < 0.0001. Furthermore, the proportion of high-risk, uninsured Black Alabamians with COPD (94.44%) substantially exceeded the percentage of high-risk, uninsured white Alabamians with COPD (59.70%). Most Alabamians with COPD (82.97%) were at low risk for substance use/abuse. Future research should explore new mechanisms for facilitating better healthcare access among high-risk Alabamians living with COPD and other prevalent comorbidities. Greater attention should be focused on Black Alabamians with COPD who cannot afford adequate health insurance.

Targeting exertional breathlessness to improve physical activity: the role of primary care

Primary care physicians (PCPs) play a crucial role in the diagnosis and management of chronic obstructive pulmonary disease (COPD). By working together with patients to target exertional breathlessness and increase physical activity, PCPs have an important role to play, early in the disease course, in improving patient outcomes in both the short and long term. In this article, we consider how physical activity affects disease progression from the PCP perspective. We discuss the role of pharmacological therapy, the importance of an holistic approach and the role of PCPs in assessing and promoting physical activity. The complexity and heterogeneity of COPD make it a challenging disease to treat. Patients' avoidance of activity, and subsequent decline in capacity to perform it, further impacts the management of the disease. Improving patient tolerance of physical activity, increasing participation in daily activities and helping patients to remain active are clear goals of COPD management. These may require an holistic approach to management, including pulmonary rehabilitation and psychological programmes in parallel with bronchodilation therapy, in order to address both physiological and behavioural factors. PCPs have an important role to optimise therapy, set goals and communicate the importance of maintaining physical activity to their patients. In addition, optimal treatment that addresses activity-related breathlessness can help prevent the downward spiral of inactivity and get patients moving again, to improve their overall health and long-term prognosis.

Characteristics of COPD Patients Prescribed ICS Managed in General Practice vs. Secondary Care

Inhaled corticosteroids (ICS) for COPD have been much debated. Our aim was to investigate characteristics of ICS prescribed COPD patients managed only in general practice compared to those also managed in secondary care. Participating general practitioners recruited patients with COPD (ICPC 2nd ed. code R95) currently prescribed ICS (ACT code R03AK and R03BA). Data on demographics, comorbidities, smoking habits, spirometry, dyspnea score and exacerbation history were retrieved from medical records. Logistic regression analysis was applied to detect predictors associated with management in secondary care. 2,279 COPD patients (45% males and mean age 71 years) were recruited in primary care. Compared to patients managed in primary care only (n = 1,179), patients also managed in secondary care (n = 560) were younger (p = 0.013), had lower BMI, more life-time tobacco exposure (p = 0.03), more exacerbations (p < 0.001) and hospitalizations (p < 0.001) and lower FEV₁/FVC-ratio (0.59 versus 0.52, respectively). Compared to patients managed in only primary care, logistic regression analysis revealed that management also in secondary care was associated to MRC-score ≥3 (OR 2.70; 95% CI 1.50-4.86; p = 0.001), FEV₁%pred (OR 0.98; 95% CI 0.95 to 0.99; p = 0.036), and systemic corticosteroids for COPD exacerbation (OR 1.44; 95% CI 1.10-1.89; p = 0.008). In COPD patients prescribed ICS recruited in primary care, patients also managed in secondary care had more respiratory symptoms, lower lung function and exacerbations treated with systemic corticosteroids indicating that the most severe COPD patients, in general, are referred for specialist care.

Impact of Frailty on Hippocampal Volume in Patients with Chronic Obstructive Pulmonary Disease

Brain frailty may be related to the pathophysiology of poor clinical outcomes in chronic obstructive pulmonary disease (COPD). This study examines the relationship between hippocampal subfield volumes and frailty and depressive symptoms, and their combined association with quality of life (QOL) in patients with COPD. The study involved 40 patients with COPD. Frailty, depressive symptoms and QOL were assessed using Kihon Checklist (KCL), Hospital Anxiety and Depression Scale (HADS), and World Health Organization Quality of Life Assessment (WHO/QOL-26). Anatomical MRI data were acquired, and volumes of the hippocampal subfields were obtained using FreeSurfer (version 6.0). Statistically, HADS score had significant association with WHO/QOL-26 and KCL scores. KCL scores were significantly associated with volumes of left and right whole hippocampi, presubiculum and subiculum, but HADS score had no significant association with whole hippocampi or hippocampal subfield volumes. Meanwhile, WHO/QOL-26 score was significantly associated with volume of the left CA1. There was a significant association between frailty, depression, and QOL. Hippocampal pathology was related to frailty and, to some extent, with QOL in patients with COPD. Our results suggest the impact of frailty on hippocampal volume and their combined associations with poor QOL in COPD.

Discharge Plan to Promote Patient Safety and Shared Decision Making by a Multidisciplinary Team of Healthcare Professionals in a Respiratory Unit

Patients with chronic obstructive pulmonary disease (COPD) often require frequent hospitalization due to worsening symptoms. Preventing prolonged hospital stays and readmission becomes a challenge for healthcare professionals treating patients with COPD. Although the integration of health and social care supports greater collaboration and enhanced patient care, organizational structure and poor leadership may hinder the implementation of patient-oriented goals. This paper presents a case of a 64-year-old chronic smoker with severe COPD who was to be discharged on long-term oxygen therapy (LTOT). It also highlights the healthcare decisions made to ensure the patient's safety at home and further provides a long-lasting solution to the existing medical and social needs. The goal was accomplished through a discharge plan that reflects multidisciplinary working, efficient leadership, and change management using Havelock's theory. While COPD is characterized by frequent exacerbation and hospital readmission, it was emphasized that most failed discharges could be attributed to bureaucratic organizational workflow which might not be in the patient's best interest. It was further demonstrated that healthcare professionals are likely to miss the window of opportunity to apply innovative and long-lasting solutions to the patient's health condition in an attempt to remedy the immediate symptoms of COPD.

The TANDEM trial: protocol for the process evaluation of a randomised trial of a complex intervention for anxiety and/or depression in people living with chronic obstructive pulmonary disease (COPD)

BACKGROUND

TANDEM is a randomised controlled trial of a complex healthcare intervention to improve the psychological and physical health of people living with chronic obstructive pulmonary disease (COPD) and anxiety and/or depression. Based on health psychology theory set out in a logic model, respiratory health professionals were recruited and trained to deliver a cognitive behavioural approach intervention (The TANDEM intervention) under the supervision of senior cognitive behavioural practitioners. Here, we describe the protocol for the process evaluation commissioned alongside the trial. A realist approach that includes attention to describing contexts and mechanisms has been adopted.

METHODS

We set up a multi-disciplinary team to develop and deliver the process evaluation. The mixed-methods design incorporates quantitative process data; monitoring of intervention fidelity; qualitative interviews with patients, carers, health professionals (facilitators) and clinical supervisors about their perspectives on acceptability of the intervention; and exploration with all stakeholders (including management/policy-makers) on future implementation. Normalisation process theory (NPT) will inform data collection and interpretation with a focus on implementation. Quantitative process data will be analysed descriptively. Qualitative interview data will be analysed before the trial outcomes are known using analytic induction and constant comparison to develop themes. Findings from the different elements will be reported separately and then integrated.

CONCLUSION

Detailed description and analysis of study processes in a research trial such as TANDEM enables research teams to describe study contexts and mechanisms and to examine the relationship with outcomes. In this way, learning from the trial goes beyond the randomised control trial (RCT) model where effectiveness is prioritised and makes it possible to explore issues arising for post-trial study implementation.

The complexity of mental health care for people with COPD: a qualitative study of clinicians' perspectives

Anxiety and depression are common mental health illnesses in people with chronic obstructive pulmonary disease (COPD). However, patients often decline formal mental health care with barriers identified at the patient, health provider and health system levels. Currently clinicians’ perspectives on this issue are not well understood. A qualitative study using semi-structured interviews was undertaken to explore clinician perceived barriers and facilitators to acceptance of psychological care amongst people with COPD. Twenty-four Australian respiratory health professionals participated. Interview transcripts were analysed thematically. An overarching theme of ‘complexity’ was identified, which was evident across five domains: (1) physical and mental health illnesses; (2) psychosocial circumstances; (3) community views and stigma; (4) educational needs and knowledge gaps; (5) navigating the health system. Targeted patient education around psychological interventions and integration of mental health clinicians within multidisciplinary outpatient respiratory services are needed to address the current challenges.

Funcionalidade da família dos pacientes com doença pulmonar obstrutiva crônica

RESUMO A doença pulmonar obstrutiva crônica (DPOC) é altamente limitante, tanto nos aspectos físicos, quanto socioemocionais, causando dificuldades significativas no cotidiano dos pacientes. Além de afetar os pacientes, a DPOC também influência na vida dos familiares e amigos próximos, pois deles vem a rede de apoio de que os pacientes necessitam. O objetivo deste artigo é avaliar a funcionalidade da família no cotidiano de pacientes acometidos por DPOC. É um estudo transversal que avaliou a funcionalidade de família de pacientes com DPOC em diferentes estágios da doença e que realizam Programa Reabilitação Cardiorrespiratória (PRC). Utilizou-se o instrumento APGAR de Família, sendo este, um acrônimo caracterizado por A = (Adaptation/Adaptação), P = (Partnership/Companheirismo), G = (Grow/Desenvolvimento), A = (Affection/Afetividade), R = (Resolve/Capacidade resolutiva), composto por 5 questões avaliadas em “sempre”, “algumas vezes” e “nunca”, o que somados resultam em “elevada disfunção familiar”, moderada disfunção familiar” e “boa funcionalidade familiar”. Foram avaliados 21 pacientes DPOC [sexo masculino (n=11; 52,3%); idade média 66,3±10 anos], com estadiamento entre moderado a muito severo. Através do APGAR da Família identificamos 2 pacientes com elevada disfunção familiar; 2 pacientes com moderada disfunção familiar; 17 pacientes com boa funcionalidade familiar. Dos que relataram elevada e moderada disfunção familiar, os acrômios mais comprometidos foram “companheirismo”, “afetividade” e “desenvolvimentos”. O grau de obstrução das vias áreas associou-se moderada e positivamente com a funcionalidade da família (r = 0,697; p = 0,004). Pacientes com DPOC participantes do PRC apresentaram boa funcionalidade familiar no seu cotidiano e a gravidade da doença esteve associada a esta funcionalidade. Pacientes que apresentaram maior disfunção familiar relataram falta de “companheirismo”, “afetividade” e “desenvolvimentos”.

Common Mental Disorders, Functional Limitation and Diet Quality Trends and Related Factors among COPD Patients in Spain, 2006-2017: Evidence from Spanish National Health Surveys

Certain conditions such as common mental disorders (CMDs), functional limitation (FL) and poor diet quality may affect the lives of individuals who suffer from chronic obstructive pulmonary disease (COPD). This study sought to examine time trends in the prevalence of CMDs, FL and diet quality among male and female COPD patients living in Spain from 2006 to 2017 and to identify which factors were related to CMDs, FL and a poor/improvable diet quality in these patients. We performed a cross-sectional study among COPD patients aged ≥ 40 years old using data from the Spanish National Health Surveys conducted in 2006, 2011 and 2017, identifying a total of 2572 COPD patients. Binary logistic regressions were performed to determine the characteristics related to CMDs, FL and poor/improvable diet quality. Over the years of the study, the prevalence of FL among female COPD patients increased (p for trend <0.001). In addition, CMDs were associated to body mass index (BMI), educational level, physical activity, smoking status, occupation, chronic conditions and alcohol consumption; FL was related to age, living with a partner, educational level, physical activity and chronic conditions; and poor/improvable diet quality was associated to age, smoking status, BMI and physical activity.

Macro and meso level influences on distributed integrated COPD care delivery: a social network perspective

Background

Care guidelines for people with chronic obstructive pulmonary disease (COPD) recommend an integrated approach for holistic, flexible, and tailored interventions. Continuity of care is also emphasised. However, many patients with COPD experience fragmented care. Discontinuities in healthcare and related social services are likely to result in disjointed rather than integrated care which can negatively affect patient health outcomes. The purpose of this qualitative study was to improve our understanding of, and how, contextual features pertaining to structures and processes of COPD integrated care influence delivery of care within patients’ healthcare networks.

Methods

We conducted individual interviews with 28 participants (9 patients, 16 healthcare professionals, and 3 spousal caregivers). Participants were recruited through the lung clinic at a city hospital in western Canada. We employed a social network paradigm to analyse and interpret the data.

Results

The analysis revealed an overarching theme of fragmented COPD care with two sub-themes: (1) Funding shortfalls and availability of resources, and (2) Dis(mis)connected communication pathways. The overarching theme depicts variations, delays, and discontinuities in patient care. The sub-themes describe how macro level influences and meso level shortfalls were perceived to influence the availability of respiratory care resources that contributed to fragmented COPD care.

Conclusions

Employing a social network lens drew particular attention to family physicians’ pivotal role in delivering community-based COPD care. While an integrated approach to care is recommended by care guidelines, institutional and organizational structures and processes, such as financial and communication structures, may inhibit delivery of integrated care. Thus, macro and meso level structures and processes have the potential to shape patient care by constraining family physicians’ purposive and communication actions necessary for facilitating an integrated distributed approach to care. We propose a context of care which fosters a context for family physicians’ delivery of patient-centered care. Integrated care delivery may improve patients’ wellbeing and alleviate financial constraints on the healthcare system.

[COPD, anxiety-depression and cognitive disorders: Does inflammation play a major role?]

COPD is a chronic respiratory disease, often associated with extrapulmonary manifestations. Co-morbidities, including anxiety, depression and cognitive impairment, worsen its progression and quality of life. The prevalence of these disorders is high, yet they are often poorly understood and inadequately managed. In the development of psychological disorders, there is accumulated evidence highlighting the major role of systemic inflammation, as well as chronic disease, genetics, the consequences of smoking, hypoxaemia, oxidative stress, and the gut microbiome In addition to traditional treatments such as bronchodilatator medications, respiratory rehabilitation and smoking cessation, systemic inflammation is an interesting therapeutic target, with the use of anti-inflammatory drugs, anti-cytokines, and nutritional interventions.

Evaluation of the Efficacy of Immersive Virtual Reality Therapy as a Method Supporting Pulmonary Rehabilitation: A Randomized Controlled Trial

Anxiety has been estimated to occur in 21–96% and depression in 27–79% of patients with chronic obstructive pulmonary disorder (COPD). We found a scarcity of literature providing evidence on how virtual reality (VR) therapy affects the intensity of depressive and anxiety symptoms and stress levels in COPD patients undergoing in-hospital pulmonary rehabilitation (PR). This study enrolled 50 COPD patients with symptoms of stress, depression, and anxiety, randomly assigned to one of two groups. The two groups participated in the traditional PR programme additionally: the VR-group performed 10 sessions of immersive VR-therapy and the control group performed 10 sessions of Schultz autogenic training. Comparison of the changes in stress levels and depressive and anxiety symptoms was the primary outcome. Analysis of the results showed a reduction in stress levels only in the VR-group (p < 0.0069), with a medium effect size (d = 0.353). The symptoms of depression (p < 0.001, d = 0.836) and anxiety (p < 0.0009, d = 0.631) were statistically significantly reduced only in the VR-group, with a strong effect size. The enrichment of pulmonary rehabilitation with immersive VR therapy brings benefits in terms of mood improvement and reduction in anxiety and stress in patients with COPD.

Effects of the Health Belief Model-Based Intervention on Anxiety, Depression, and Quality of Life in Chronic Obstructive Pulmonary Disease

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is a chronic respiratory condition. COPD causes a heavy burden on the patients through negative impacts on the quality of life and psychological health. The health belief model (HBM) is proposed and modified by several social psychologists and is confirmed to have benefits in the recovery of various diseases. This research aimed to explore the effects of the HBM-based intervention on anxiety, depression, and quality of life in COPD patients entering pulmonary rehabilitation (PR).

METHODS

This research was conducted at the Tianjin Rehabilitation Recuperate Center of Chinese PLA in 2019. A total of 136 COPD patients were randomized into the intervention group and the control group. In the control group, patients received the PR program. In the intervention group, patients received both PR program and the HBM-based intervention. Quality of life was measured by the COPD assessment test. The outcomes of anxiety and depression were measured by the Hospital Anxiety and Depression Scale.

RESULTS

The HBM-based intervention decreased both anxiety and depression scores among COPD patients. The COPD assessment test score was declined by the HBM-based intervention, which also decreased the serum levels of interleukin-6 and C-reactive protein in COPD patients entering PR.

CONCLUSION

The HBM-based intervention alleviates anxiety and depression, enhances quality of life, and inhibits inflammation in COPD patients entering PR.

Utilizing an Artificial Neural Network to Predict Self-Management in Patients With Chronic Obstructive Pulmonary Disease: An Exploratory Analysis

PURPOSE

The main objective of this study was to utilize an artificial neural network in an exploratory fashion to predict self-management behaviors based on reported symptoms in a sample of stable patients with chronic obstructive pulmonary disease (COPD).

DESIGN AND METHODS

Patient symptom data were collected over 21 consecutive days. Symptoms included distress due to cough, chest tightness, distress due to mucus, dyspnea with activity, dyspnea at rest, and fatigue. Self-management abilities were measured and recorded periodically throughout the study period and were the dependent variable for these analyses. Self-management ability scores were broken into three equal tertiles to signify low, medium, and high self-management abilities. Data were entered into a simple artificial neural network using a three-layer model. Accuracy of the neural network model was calculated in a series of three models that respectively used 7, 14, and 21 days of symptom data as input (independent variables). Symptom data were used to determine if the model could accurately classify participants into their respective self-management ability tertiles (low, medium, or high scores). Through analysis of synaptic weights, or the strength or amplitude of a connection between variables and parts of the neural network, the most important variables in classifying self-management abilities could be illuminated and served as another outcome in this study.

FINDINGS

The artificial neural network was able to predict self-management ability with 93.8% accuracy if 21 days of symptom data were included. The neural network performed best when predicting the low and high self-management abilities but struggled in predicting those with medium scores. By analyzing the synaptic weights, the most important variables determining self-management abilities were gender, followed by chest tightness, age, cough, breathlessness during activity, fatigue, breathlessness at rest, and phlegm.

CONCLUSIONS

The results of this study suggest that self-management abilities could potentially be predicted through understanding and reporting of patient's symptoms and use of an artificial neural network. Future research is clearly needed to expand on these findings.

CLINICAL RELEVANCE

Symptom presentation in chronically ill patients directly impacts self-management behaviors. Patients with COPD experience a number of symptoms that have the potential to impact their ability to manage their chronic disease, and artificial neural networks may help clinicians identify patients at risk for poor self-management abilities.

Heavy shackles: The experience of symptom distress and coping behaviors of Chinese patients with chronic obstructive pulmonary disease

People with chronic obstructive pulmonary disease exhibit various symptoms, some of which can negatively affect their daily lives. Thus, they may adopt coping behaviors to improve their condition. This qualitative descriptive study investigated symptom distress and coping behaviors among 19 Chinese patients with chronic obstructive pulmonary disease using individual, semi-structured, face-to-face interviews. We identified the following three themes for the patients' symptom distress: distressing symptoms, inescapable imprisonment, and no choice other than being a burden to the family. The various coping behaviors of the patients were categorized into the following three themes: struggle during the medical treatment process, careful maintenance of daily life, and coping with negative emotions. Although all patients experienced physical and psychological distress, they displayed a strong desire to improve their lives and health. By recognizing the patients' symptom distress and coping behaviors, tailored interventions could be developed to improve the quality of their lives.

The effect of back massage on physiological parameters, dyspnoea, and anxiety in patients with chronic obstructive pulmonary disease in the intensive care unit: A randomised clinical trial

OBJECTIVE

This study aimed to examine the effect of back massage on physiological parameters, dyspnoea and anxiety in patients with chronic obstructive pulmonary disease receiving noninvasive mechanical ventilation in the intensive care unit.

DESIGN AND METHODS

This study was a randomised controlled trial. Patients in the intervention group received back massage (15 minutes) between 16.00 and 20.00 every day for four days in the intensive care unit. The control group received no intervention. The data was collected using a personal information form, Baseline Dyspnoea Index, State-Trait Anxiety Inventory and Physiological Parameters Chart.

RESULTS

We found no statistically significant change between systolic-diastolic blood pressures, heart rates and respiratory rate, oxygen saturation and dyspnoea level of the intervention and control groups (p > .05), while there was a significant reduction in the anxiety scores of patients in the intervention group (p < .05).

CONCLUSION

This study found that back massage applied in patients with chronic obstructive pulmonary disease receiving noninvasive mechanical ventilation was effective in decreasing anxiety. Back massage is a low-cost intervention with benefits for patients, and it may be a useful intervention in the anxiety management of intensive care patients.

Hypnosis for the Management of Anxiety and Dyspnea in COPD: A Randomized, Sham-Controlled Crossover Trial

Background

Patients with chronic obstructive pulmonary disease (COPD) are prone to dyspnea, increased respiratory rate and other anxiety-inducing symptoms. Hypnosis constitutes a complementary procedure capable of improving subjective feelings of anxiety.

Objective

Assessing the efficacy of a 15-minute hypnosis intervention for immediate improvement of anxiety in severe COPD patients.

Methods

Twenty-one participants, COPD patients (mean FEV1 < 32.3%), were randomly assigned to two individual sessions in crossover (sham and hypnosis, 24-h washout period, arms: hypnosis-sham [n=11]/sham-hypnosis [n=10]). We tracked pre- and post-intervention anxiety (STAI-6 score) as primary endpoint.

Results

Nineteen (90.5%) participants completed the study. Anxiety diminished significantly after hypnosis (STAI-6 scores −23.8% [SD = 18.4%] hypnosis vs −3.1% [32.8%] sham; χ²=8, P<0.01, Bayes Factor 5.5). Respiratory rate also decreased after hypnosis. Improvements in SpO2 and Borg exertion scores were registered after both conditions.

Conclusion

A 15-minute hypnosis session improved participants’ anxiety and lowered respiratory rate (as opposed to sham). Improvements in anxiety were correlated with an alleviation in respiratory strain. Results imply that hypnosis can contribute to the improvement of anxiety levels and breathing mechanics in severe COPD patients.

Depression in Chronically ill Patients of Railway General Hospital, Pakistan

According to the World Health Organization (WHO), chronic diseases are the leading cause of death and disability worldwide and estimated to contribute to 73% of all deaths by 2020. In addition to the difficulty in effectively managing chronic diseases, they are often complicated further by the co-morbid depression stemming from the original disease. Depression has the highest burden of disease affecting more than 264 million people worldwide and worsens the burden of co-existing chronic medical diseases as well. A bidirectional relation exists between depression and chronic medical diseases. Statistical mapping of chronically ill patients of Pakistan suggests that 50% of its population suffers from some form of chronic disease. Little data exists for the prevalence of depression in chronically ill patients from most of Pakistan. Our objectives were to observe the patterns of depression in chronically ill patients and outline the need for intervention (if any) on a population of Railway General Hospital (RGH - a tertiary healthcare hospital in Rawalpindi, Pakistan). We also aimed at finding out the relation (if any) of age, gender, number of hospital admissions, education and effectiveness of medical disease management with depression. A cross sectional study was conducted on patients admitted due to their chronic medical diseases out of a population of 11,000 presenting at the medical OPD of RGH over a period of three months using Patient Health Questionnaire-9 (PHQ -9) Urdu version. About 50% of the patients suffered from moderate to severe forms of depression. A significant positive correlation was found between age and past psychiatric history of illnesses other than depression with depression while no significance was found with number of hospital admissions, gender or education level; 35% had suicidal ideation. Depression is quite often dismissed, underdiagnosed and leads to a poor quality of life and decrease in cost effectiveness in our population. Pakistan needs to use more resources on managing depression and medical professionals need to change their attitudes in holistically managing the patients. Treating depression is just as important as managing other symptoms of chronic medical diseases.

Latent Health Risk Classes Associated with Poor Physical and Mental Outcomes in Workers with COPD from Central Appalachian U.S. States

Adults who work in the Central Appalachian region of the United States (U.S.) are disproportionately affected by Chronic Obstructive Pulmonary Disease (COPD). While there is a socio-demographic profile of adults with COPD who are at increased risk for physical and mental distress, the risk factors that uniquely affect the health-related quality of life (HRQoL) of Central Appalachian workers with COPD are unknown. Therefore, we conducted a latent class analysis of 2016 and 2017 Behavioral Risk Factor Surveillance System data from 1326 currently employed adults with COPD living in four U.S. states (KY, NC, TN, and WV) within the Central Appalachian Region. Drawing from the social ecological model, we identified associations between theoretically informed risk indicators-comorbid health conditions, substance use and abuse, and limited access to healthcare-on three HRQoL variables, including infrequent (0-13 days) or frequent (≥14 days) physical distress, mental distress, and limited activity due to poor health over the past 30 days. Workers at high risk for comorbid conditions reported more frequent physical distress, mental distress, and activity limitations as compared to those at low risk. Workers reporting difficulty accessing healthcare were no more likely to report physical or mental distress when compared to workers with adequate access to healthcare; however, those with limited healthcare access did report more frequent activity limitation due to poor health. Interestingly, workers with COPD at high risk for substance use and abuse were no more likely to report poor HRQoL outcomes compared to those at low risk. Our findings have important implications for addressing indicators of poor health among Central Appalachian workers with COPD, especially those living with multiple comorbidities.

Single-Inhaler Triple Therapy and Health-Related Quality of Life in COPD: The IMPACT Study

Introduction

The phase 3 InforMing the PAthway of COPD (chronic obstructive pulmonary disease) Treatment (IMPACT) trial, single-inhaler therapy with fluticasone furoate (FF) 100 μg, umeclidinium (UMEC) 62.5 μg, and vilanterol (VI) 25 μg demonstrated a reduction in the rate of moderate or severe exacerbations compared with FF/VI or UMEC/VI in patients with symptomatic COPD at risk of exacerbations. This article reports additional evidence of improvements in symptoms and health-related quality of life (HRQoL) with FF/UMEC/VI compared with either FF/VI or UMEC/VI from the IMPACT study.

Methods

Patient-reported HRQoL assessments and symptom measures included as pre-specified IMPACT end points were the St George's Respiratory Questionnaire (SGRQ), COPD Assessment Test (CAT), and Baseline Dyspnea Index (BDI) as the anchor for the Transitional Dyspnea Index (TDI) focal score (BDI/TDI) in a subset of patients enrolled at study sites in North America and Europe. Change from baseline was assessed at weeks 4, 28, and 52.

Results

The intent-to-treat population included 10,355 patients (TDI population: 5058 patients). Clinically meaningful improvements in SGRQ total score between baseline and week 52 favored FF/UMEC/VI over FF/VI (− 1.8 units, p < 0.001) and UMEC/VI (− 1.8 units, p < 0.001). Similar improvements in the CAT and TDI focal score were also observed with FF/UMEC/VI versus FF/VI or UMEC/VI.

Conclusions

This study demonstrates that in patients with symptomatic COPD at risk of exacerbations, once-daily FF/UMEC/VI, compared with FF/VI or UMEC/VI, improves patient-perceived HRQoL and symptoms.

Singing Improves Oxygen Saturation in Simulated High-Altitude Environment

At high altitude, low oxygen partial pressure predisposes human body to hypobaric hypoxia that may lead to high-altitude illness. Currently, singing had been used for rehabilitation of patients with lung diseases but its role in high-altitude low oxygen environment is still scarce. This study aims to examine the effect of singing in improving oxygen saturation at different levels of high altitudes in a hypobaric chamber. Eight healthy volunteers were assigned to three interventions at three simulated altitudes (sea level, 3000 m and 5000 m). The oxygen saturation (SpO₂) was measured via pulse oximetry under three conditions: no singing (NS), singing aloud (SA), and singing silently (SS). The "birthday song" was used as the standard song for 4 minutes. At sea level, mean NS SpO₂ was 97.75% ± 1.04%. With SS, the level increased to 98.25% ± 1.04%. Mean SA SpO₂ increased to 98.38% ± 0.92% (P < 0.05). At 3000 m, mean NS SpO₂ was 92.75% ± 3.73% and rose to 94.50% ± 2.51% and 94.63% ± 2.00% respectively with SA and SS (P < 0.05). At 5000 m, NS level of 79.88P ± 3.60% increased to 82.13 ± 5.87 and 82.88% ± 7.12% with SA and SS respectively (P < 0.05). The repeated measure ANOVA showed significant difference for altitude (P < 0.001) and intervention (P = 0.05). In conclusion, singing both either "aloud" or "silently" significantly increased the level of SpO₂ in simulated high altitude at 3000 m and above. The study suggests that singing as a potential intervention to improve oxygen saturation at high altitudes. Study with larger sample in hypobaric chamber as well as in real environment is recommended.

Incorporating Comprehensive Assessment Parameters to Better Characterize and Plan Rehabilitation for Persons with Chronic Obstructive Pulmonary Disease

OBJECTIVES

The current management of chronic obstructive pulmonary disease (COPD) largely ignores its heterogeneous pulmonary and extrapulmonary manifestations in the individual patient. This study aimed to identify clusters of patients with COPD based on a thorough traits assessment.

DESIGN

An observational, prospective, single-center study.

SETTING AND PARTICIPANTS

Patients with COPD referred by chest physicians for a comprehensive pulmonary rehabilitation program to CIRO (Horn, the Netherlands) were eligible to participate. CIRO is a specialized pulmonary rehabilitation center in the southern part of the Netherlands for patients with complex underlying respiratory diseases.

METHODS

Clinically stable patients with COPD underwent a comprehensive assessment, including pulmonary traits (airflow limitation, static hyperinflation, gas transfer, respiratory pressures, and arterial blood gases), extrapulmonary functional traits, and health status (quadriceps muscle strength, physical functioning, body composition, comorbidities, symptoms perception, and social and emotional functioning). Clusters were generated using the SOM-Ward Cluster algorithm, a hybrid algorithm that applies the classical hierarchical method of Ward on top of the self-organizing map topology.

RESULTS

Based on the abovementioned attributes of 518 patients with mild to very severe COPD (44% women, age 64.1 ± 9.1 years, forced expiratory volume in the first second 48.6% ± 20.0% of predicted), 7 clusters were identified. Clusters had unique patterns differing in demographics, pulmonary, extrapulmonary functional, and behavioral traits and/or health status.

CONCLUSION AND IMPLICATIONS

The tremendous heterogeneity in pulmonary, extrapulmonary functional and behavioral traits, and health status in patients with COPD supports the need for an individual comprehensive assessment and a goal-directed personalized management strategy.

Involvement of the gabaergic, serotonergic and glucocorticoid mechanism in the anxiolytic-like effect of mastoparan-L

Mastoparan-L (mast-L) is a cell-penetrating tetradecapeptide and stimulator of monoamine exocytosis. In the present study, we evaluated the anxiolytic-like effect of mast-L. Preliminary pharmacological tests were conducted to determine the most appropriate route of administration, extrapolate dose and detect potential toxic effects of this peptide. Oral and intracerebroventricular administration of mast-L (0.1, 0.3 or 0.9 mg.kg^-1), diazepam (1 or 5 mg.kg^-1), buspirone (10 mg.kg^-1) or vehicle 10 mL.kg^-1 was carried out prior to the exposure of mice to the anxiety models: open field, light-dark box and elevated plus-maze. To characterize the mechanism underlying the antianxiety-like effect of mast-L, pharmacological antagonism, blood plasma analysis, molecular docking, and receptor binding assays were performed. The absence of a neurotoxic sign, animal's death as well as lack of significant changes in the relative organ weight, hematological and biochemical parameters suggest that mast-L is relatively safe. The anxiolytic-like effect of mast-L was attenuated by flumazenil (antagonist of benzodiazepine binding site) and WAY100635 (selective antagonist of 5-HT_1A receptors) pretreatments. Mast-L reduced plasma corticosterone and lowered the scoring function at GABA_A -18.48 kcal/mol (Ki = 155 nM), 5-HT_1A -22.39 kcal/mol (Ki = 130 nM), corticotropin-releasing factor receptor subtype 1 (CRF1) -11.95 kcal/mol (Ki = 299 nM) and glucocorticoid receptors (GR) -14.69 kcal/mol (Ki = 3552 nM). These data fit the binding affinity (Ki) and demonstrate the involvement of gabaergic, serotonergic and glucocorticoid mechanisms in the anxiolytic-like property of mast-L.

The positive association between employment and self-reported mental health in the USA: a robust application of marginalized zero-inflated negative binomial regression (MZINB)

BACKGROUND

Few studies have assessed the impact of employment on mental health among chronically ill patients. This study investigated the association between employment and self-reported mental unhealthy days among US adults.

METHODS

For this cross-sectional cohort study, we pooled 2011-2017 Behavioral Risk Factor Surveillance System (BRFSS) survey data. We examined the association between employment and mental health in nine self-reported chronic conditions using marginalized zero-inflated negative binomial regression (MZINB). All analyses were conducted using SAS statistical software 9.4.

RESULTS

Respondents (weighted n = 245 319 917) were mostly white (77.16%), aged 18-64 (78.31%) and employed (57.08%). Approximately 10% of respondents reported one chronic condition. Expected relative risk of mental unhealthy days was highest for employed respondents living with arthritis (RR = 1.70, 95% CI = [1.66, 1.74]), COPD (RR = 1.45, 95% CI = [1.41, 1.49]) and stroke (RR = 1.31, 95% CI = [1.25, 1.36]) compared to unemployed respondents. Employed males had 25% lower risk of self-reported mental unhealthy days compared to females.

CONCLUSIONS

Results show the interactive effects of employment on self-reported mental health. Employment may significantly impact on self-reported mental health among patients suffering from chronic conditions than those without chronic conditions.

Management of the COPD Patient with Comorbidities: An Experts Recommendation Document

Background

Chronic obstructive pulmonary disease (COPD) is associated with multiple comorbidities, which impact negatively on patients and are often underdiagnosed, thus lacking a proper management due to the absence of clear guidelines.

Purpose

To elaborate expert recommendations aimed to help healthcare professionals to provide the right care for treating COPD patients with comorbidities.

Methods

A modified RAND-UCLA appropriateness method consisting of nominal groups to draw up consensus recommendations (6 Spanish experts) and 2-Delphi rounds to validate them (23 Spanish experts) was performed.

Results

A panel of Spanish internal medicine experts reached consensus on 73 recommendations and 81 conclusions on the clinical consequences of the presence of comorbidities. In general, the experts reached consensus on the issues raised with regard to cardiovascular comorbidity and metabolic disorders. Consensus was reached on the use of selective serotonin reuptake inhibitors in cases of depression and the usefulness of referring patients with anxiety to respiratory rehabilitation programmes. The results also showed consensus on the usefulness of investigating the quality of sleep, the treatment of pain with opioids and the evaluation of osteoporosis by lateral chest radiography.

Conclusion

This study provides conclusions and recommendations that are intended to improve the management of the complexity of patients with COPD and important comorbidities, usually excluded from clinical trials.

Care Transitions in the Psychiatric Hospital: Focus on Older Adults

Patients undergoing a care transition are vulnerable to duplication of services, conflicting care recommendations, and errors in medication reconciliation. Older adults may be more vulnerable to care transitions given their relatively higher medical burden, cognitive impairment, and frequent polypharmacy. In this Treatment in Geriatric Mental Health: Research in Action article, we first present the results of a quality improvement study examining the frequency of care transitions to and from the medical hospital among patients admitted to a university-affiliated psychiatric hospital. Among a sample of 50 geriatric adults and 50 nongeriatric adults admitted to the psychiatric hospital, we tallied the number of care transitions to and from the medical hospital. We found that the geriatric cohort was significantly more likely to experience this type of care transition (p = 0.012, Fisher's exact test) compared to the nongeriatric cohort. In the second part of this article, we use a clinical vignette to illustrate the types of medical errors that can occur as a vulnerable and frail older adult moves between acute psychiatric and medical settings. Finally, we list provider-level and systems-level evidence-based recommendations for how care of the patient in the vignette could be improved. The quality improvement study and clinical vignette demonstrate how older adults are at greater risk for care transitions to and from the acute medical setting during psychiatric hospitalization, and that creative solutions are required to improve outcomes.

Understanding the impact of chronic obstructive pulmonary disease exacerbations on patient health and quality of life

Exacerbations of chronic obstructive pulmonary disease (COPD) represent a significant clinical problem, and are associated with decreased lung function, worsening quality of life and decreased physical activity levels, with even a single exacerbation having detrimental effects. The occurrence of COPD exacerbations can also have a considerable impact on healthcare costs and mortality rates, with over one-fifth of patients hospitalized for a COPD exacerbation for the first time dying within one year of discharge. This highlights the need for COPD exacerbations to be a major focus in clinical practice. Furthermore, the substantial effect that COPD exacerbations can have on patient mental health should not be underestimated. Despite their clinical importance, COPD exacerbations are poorly recognized and reported by patients, and improving patient understanding and reporting of exacerbations to ensure prompt treatment may minimize their deleterious effects. Renewed focus on improving current clinical practice with support from evidence-based guidelines is required. This also raises a challenge to payors, healthcare systems and government policies to do more to tackle the considerable outstanding burden of COPD exacerbations.
