Depression and anxiety in patients with interstitial lung disease

A digital therapy targeting anxiety in pulmonary fibrosis: A decentralized randomized controlled trial

BACKGROUND AND OBJECTIVE

Pulmonary fibrosis, a manifestation of interstitial lung disease, is frequently associated with anxiety. The objective of this study, COMPANION, was to assess the anxiolytic efficacy of Almee, a digital cognitive behavioural therapy for patients with pulmonary fibrosis, compared to treatment as usual.

METHODS

COMPANION was a randomized, controlled, open-label and partly reader-blinded, decentralized, clinical trial conducted in the United States. Eligible patients had radiology-confirmed pulmonary fibrosis and a Generalized Anxiety Disorder 7-item (GAD-7) score of ≥5 (possible range 0-21). Participants were randomized 1:1 to Almee or no intervention for 9 weeks, with block stratification by anxiety severity. The primary endpoint was change in GAD-7 score from baseline to week 9. Between 20 December 2022 and 14 August 2023, 108 participants were randomized, 54 to Almee and 54 to treatment as usual.

RESULTS

In each arm, 46 participants completed the study; 108 cases were analysed as intention-to-treat. By week 9, average GAD-7 score had improved by 1.8 points (SEM = 2.1) in the Almee group (n = 54) and deteriorated by 0.9 points (SEM = 2.2) in the control group (n = 54), a 2.7-point difference (95% confidence interval: 1.2-4.2, p = 0.0006).

CONCLUSION

Treatment with Almee was well-tolerated and showed clinically meaningful improvement in pulmonary fibrosis-related anxiety. Almee shows promise as a personalized intervention for management of the psychological burden related to living with pulmonary fibrosis.

Understanding the Determinants and Outcomes of Education in Pulmonary Rehabilitation: Moving Toward Person-Centered Care

TOPIC IMPORTANCE

Education and psychosocial support are essential components of pulmonary rehabilitation (PR). However, the delivery of education often follows a one-size-fits-all approach, with individual factors that influence learning rarely considered. Moreover, education-related outcomes are frequently overlooked in PR assessments, and their inconsistent use has limited our understanding of education's impact on people with chronic respiratory diseases. There is a clear need for practical guidance to identify key learning determinants and to define targeted education outcomes, ultimately optmizing PR and establishing quality standards.

REVIEW FINDINGS

Cognitive function, health literacy, psychological status, and social connection can influence an individual's ability to learn. Without proper consideration and assessment, these factors can otherwise become barriers to education and effective self-management. Education in PR should aim to: (1) improve individuals' knowledge to foster informed and active participants; (2) develop their skills to enable autonomy and competence; and (3) enhance their confidence to apply this knowledge and skills in daily life.

SUMMARY

This review emphasizes the importance of person-centered education in PR, provides a framework for understanding which education-related outcomes to target, and highlights the need for future research to enhance this essential component.

Patient perspectives on educational needs in scleroderma-interstitial lung disease

Background

Systemic sclerosis is a chronic and rare connective tissue disease with multiorgan effects, including interstitial lung disease (ILD). Navigating systemic sclerosis-interstitial lung disease presents a challenge for patients due to the gaps in patient education, which can impact patient health and quality of life. This study utilized the nominal group technique to identify priority knowledge gaps among patients with systemic sclerosis-interstitial lung disease and inform future educational interventions and research.

Methods

We conducted four structured group sessions using the nominal group technique. Patients with systemic sclerosis-interstitial lung disease were presented with two questions that aimed to identify knowledge gaps. Following participant ranking, investigators performed a thematic analysis of the patients' responses to categorize the generated knowledge gaps.

Results

Twenty-one patients were interviewed and ranked the top three themes for the first question (What questions about your scleroderma-lung disease that you have keep you awake at night?), based on total points, as: (1) Understanding progression, its impacts on the body, and managing health changes (39.7%); (2) anticipating future symptoms and implementing strategies for management and coping (19.8%); and (3) employing and understanding non-pharmacological interventions and self-management strategies (17.5%). The top three themes for the second question (What information do you want about your scleroderma-lung disease that you cannot find?) ranked by total points were: (1) understanding progression, its impacts on the body, and managing health changes (41.3%); (2) navigating health system barriers (16.7%); and (3) research efforts toward treating scleroderma (10.3%).

Conclusions

Our study underscores the importance of understanding the educational needs of patients with systemic sclerosis-interstitial lung disease. Patient responses emphasize the need to comprehensively address concerns about disease management, coping with impacts on social life, and navigating the healthcare system. By addressing these multifaceted concerns, we can design and implement patient-centered education to empower patients through increased support.

Patient-centered care in pulmonary fibrosis: access, anticipate, and act

Comprehensive care integrates individual patient needs and is highly valued for patients with pulmonary fibrosis (PF). The importance of a patient-centered care approach is rooted in the unpredictable progressiveness of the disease course in PF. The respiratory impairment associated with PF has a major impact on the quality of life for both patients and their caregivers. We believe that prioritizing patient preferences could improve the shared decision making process and may ultimately lead to better health outcomes. Despite the growing emphasis for this approach, it remains challenging to adopt it in clinical practice. In this review, we propose the comprehensive Triple A Care Model, consisting of the domains Access, Anticipate, and Act, which emphasizes core elements of patient-centered care for patients with PF. We will provide an overview of the unmet needs in care for patients with PF and elaborate on the current methods for delivering patient-centered care. The latest insights into symptom management and supportive measures and several approaches to improving access to care are discussed, in line with the most recent guidelines.

Assessing health-related quality of life in patients with interstitial lung diseases

BACKGROUND

The R-Scale-PF was proposed to evaluate the health-related quality of life (HRQoL) in patients with idiopathic pulmonary fibrosis (IPF). We generated a German version of the R-Scale-PF (GR-Scale), representing the first translation of the questionnaire into another language and assessed HRQoL longitudinally in various interstitial lung diseases (ILDs) using the R-Scale-PF scoring system at a specialized ILD centre.

METHODS

We have translated the questionnaire in accordance with the WHO translation guidelines and applied it to 80 ILD patients of our department, with follow-ups after 3-6 months, assessing its internal consistency, floor and ceiling effects, concurrent validity, known-groups validity, and its responsiveness to changes over time.

RESULTS

At baseline, all 80 patients completed the GR-Scale. In 70 patients (87.5%), follow-up data could be obtained after 4.43 ± 1.2 months. The GR-Scale demonstrated acceptable internal consistency (Cronbach's α 0.749) and slight floor effects. Concurrent validity analysis showed weak but significant correlations with forced vital capacity (FVC; r=-0.282 p = 0.011) and diffusion capacity for carbon monoxide (DLco; r=-0.254 p = 0.025). In the follow-up analysis, moderate correlations were found with FVC (r=-0.41 p < 0.001) and DLco (r=-0.445 p < 0.001). No significant difference in the total score was found between patients with IPF (n = 10) and with non-IPF ILDs (n = 70). The GR-Scale successfully discriminated between groups of varying disease severity based on lung function parameters and the need for long-term oxygen therapy (LTOT). Furthermore, it was able to distinguish between patients showing improvement, stability or decline of lung function parameters.

CONCLUSION

Our prospective observational pilot study suggests that the GR-Scales is a simple and quick tool to measure HRQoL in patients with ILDs, thus providing an important additional information for the clinical assessment of ILD patients.

The prevalence of anxiety in respiratory and sleep diseases: A systematic review and meta-analysis

BACKGROUND

Anxiety is common in those with chronic physical health conditions and can have significant impacts on both quality of life and physical health outcomes. Despite this, there are limited studies comprehensively investigating the prevalence of anxiety in respiratory and sleep medicine settings. This systematic review and meta-analysis aims to provide insight into the global prevalence of anxiety symptoms/disorders in respiratory and sleep medicine outpatients.

METHODS

PubMed, Embase, Cochrane, PsycINFO and Google Scholar databases were searched from database inception to January 23, 2023 for studies assessing the prevalence of anxiety in adult (≥16 years) respiratory and sleep medicine outpatients. Data was screened and extracted independently by two investigators. Anxiety was measured using various self-report questionnaires, structured interviews, and/or patient records. Using CMA software for the meta-analysis, a random-effects model was used for pooled estimates, and subgroup analysis was conducted on relevant models using a mixed-effects model.

RESULTS

116 studies were included, featuring 36,340 participants across 40 countries. The pooled prevalence of anxiety was 30.3 % (95%CI 27.9-32.9 %, 10,679/36,340). Subgroup analysis found a significant difference across type of condition, with pulmonary tuberculosis the highest at 43.1 % and COVID-19 outpatients the lowest at 23.4 %. No significant difference was found across anxiety types, country or age. Female sex and the use of self-report measures was associated with significantly higher anxiety estimates.

CONCLUSIONS

Anxiety is a common experience amongst patients in respiratory and sleep medicine outpatient settings. Thus, it is crucial that anxiety identification and management is considered by physicians in the field.

Knowledge, attitude, and practice toward interstitial lung disease among patients: a cross-sectional study

Objective

To explore the knowledge, attitude, and practice (KAP) toward interstitial lung disease (ILD) among patients and analyze the factors affecting KAP.

Methods

This cross-sectional study enrolled patients with ILD treated at the Respiratory Department of Shanghai Pulmonary Hospital between January 2023 and June 2023. A self-administered questionnaire was developed to evaluate their KAP toward ILD through convenient sampling. Multivariate regression analysis and structural equation model (SEM) were used to analyze the factors influencing KAP and their interactions.

Results

A total of 397 patients were enrolled, with 61.71% male. The mean KAP scores were 4.60 ± 3.10 (possible range: 0-12), 16.97 ± 2.16 (possible range: 5-25), and 32.60 ± 7.16 (possible range: 9-45), respectively. Multivariate logistic regression analysis showed that junior high school [OR = 2.003, 95%CI: 1.056-3.798, p = 0.033], high school and above [OR = 2.629, 95%CI: 1.315-5.258, p = 0.006], and duration of disease ≥5 years [OR = 1.857, 95%CI: 1.132-3.046, p = 0.014] were independently associated with adequate knowledge. The knowledge [OR = 1.108, 95%CI: 1.032-1.189, p = 0.005] and duration of disease ≥5 years [OR = 0.525, 95%CI: 0.317-0.869, p = 0.012] were independently associated with a positive attitude. The knowledge [OR = 1.116, 95%CI: 1.036-1.202, p = 0.004], attitude [OR = 1.180, 95%CI: 1.061-1.312, p = 0.002], and the age of >70 years [OR = 0.447, 95%CI: 0.245-0.817, p = 0.009] were independently associated with the proactive practice. SEM showed that patients' knowledge of ILD directly affected their attitude (β = 0.842, p < 0.001) and practice (β = 0.363, p < 0.001), and their attitude also affected their practice (β = 0.347, p = 0.014).

Conclusion

Patients with ILD in China had poor knowledge, intermediate attitude, and proactive practice toward ILD, which suggests that the health education of patients should be further strengthened.

Nurse and Social Worker Palliative Telecare Team and Quality of Life in Patients With COPD, Heart Failure, or Interstitial Lung Disease: The ADAPT Randomized Clinical Trial

Importance

Many patients with chronic obstructive pulmonary disease (COPD), heart failure (HF), and interstitial lung disease (ILD) endure poor quality of life despite conventional therapy. Palliative care approaches may benefit this population prior to end of life.

Objective

Determine the effect of a nurse and social worker palliative telecare team on quality of life in outpatients with COPD, HF, or ILD compared with usual care.

Design, Setting, and Participants

Single-blind, 2-group, multisite randomized clinical trial with accrual between October 27, 2016, and April 2, 2020, in 2 Veterans Administration health care systems (Colorado and Washington), and including community-based outpatient clinics. Outpatients with COPD, HF, or ILD at high risk of hospitalization or death who reported poor quality of life participated.

Intervention

The intervention involved 6 phone calls with a nurse to help with symptom management and 6 phone calls with a social worker to provide psychosocial care. The nurse and social worker met weekly with a study primary care and palliative care physician and as needed, a pulmonologist, and cardiologist. Usual care included an educational handout developed for the study that outlined self-care for COPD, ILD, or HF. Patients in both groups received care at the discretion of their clinicians, which could include care from nurses and social workers, and specialists in cardiology, pulmonology, palliative care, and mental health.

Main Outcomes and Measures

The primary outcome was difference in change in quality of life from baseline to 6 months between the intervention and usual care groups (FACT-G score range, 0-100, with higher scores indicating better quality of life, clinically meaningful change ≥4 points). Secondary quality-of-life outcomes at 6 months included disease-specific health status (Clinical COPD Questionnaire; Kansas City Cardiomyopathy Questionnaire-12), depression (Patient Health Questionnaire-8) and anxiety (Generalized Anxiety Disorder-7) symptoms.

Results

Among 306 randomized patients (mean [SD] age, 68.9 [7.7] years; 276 male [90.2%], 30 female [9.8%]; 245 White [80.1%]), 177 (57.8%) had COPD, 67 (21.9%) HF, 49 (16%) both COPD and HF, and 13 (4.2%) ILD. Baseline FACT-G scores were similar (intervention, 52.9; usual care, 52.7). FACT-G completion was 76% (intervention, 117 of 154; usual care, 116 of 152) at 6 months for both groups. Mean (SD) length of intervention was 115.1 (33.4) days and included a mean of 10.4 (3.3) intervention calls per patient. In the intervention group, 112 of 154 (73%) patients received the intervention as randomized. At 6 months, mean FACT-G score improved 6.0 points in the intervention group and 1.4 points in the usual care group (difference, 4.6 points [95% CI, 1.8-7.4]; P = .001; standardized mean difference, 0.41). The intervention also improved COPD health status (standardized mean difference, 0.44; P = .04), HF health status (standardized mean difference, 0.41; P = .01), depression (standardized mean difference, -0.50; P < .001), and anxiety (standardized mean difference, -0.51; P < .001) at 6 months.

Conclusions and Relevance

For adults with COPD, HF, or ILD who were at high risk of death and had poor quality of life, a nurse and social worker palliative telecare team produced clinically meaningful improvements in quality of life at 6 months compared with usual care.

Development and initial validation of the ILD-Anxiety-Questionnaire (IAQ): A new instrument for assessing disease specific fears in interstitial lung disease

INTRODUCTION

Multiple studies focusing on chronic lung diseases (i.e. COPD), have indicated that the quality of life (QoL) can be impacted by disease-related fears. In the context of Interstitial Lung Diseases (ILD), however, these have never been systematically examined. Therefore, the aim of the present study was to develop and evaluate an appropriate measuring tool, and to investigate the influence of disease-related anxieties on QoL in ILD.

METHOD

N = 166 ILD patients participated in the study and completed an itempool on disease-related fears, based on the COPD-Anxiety-Questionnaire (CAF-R) and expert assessments. Further, demographic and psychological variables were assessed (anxiety: GAD-7, QoL: K-BILD; Beliefs about Health: KKG). Psychometric properties were analyzed (factor structure, reliability, validity). Regression analyses were used to calculate the differential predictive power of disease-related anxieties on QoL.

RESULTS

The factor structure was confirmed (Scales: Fear-of-Dependence-and-Progression, Fear-of-Social-Exclusion-and-Isolation, Fear-of-Physical-Activity, Fear-of-Dyspnea, and Sleep-related- Complaints). The Scales showed satisfying reliabilities (α = 0.68 to 0.89) and good validity. Disease-related anxieties proved to be differential predictors for different scales of the K-BILD (ß = -0.15 to ß = -0.58, all ps < .01).

CONCLUSIONS

The ILD-Anxiety-Questionnaire (IAQ) is an easy-to-use, valid measurement tool for assessing disease-related anxieties. These vary in their impact on different aspects of QoL. Therefore, it might aid in specifying the indication for potential psychological supplementary interventions. Additional long-term studies are required to investigate how specific anxieties affect both overall and condition-specific QoL in diverse situations.

Influence of pulmonary rehabilitation on symptoms of anxiety and depression in interstitial lung disease: A systematic review of randomized controlled trials

BACKGROUND

Interstitial lung diseases (ILDs) cause fibrosis of lung parenchyma, leading to impaired quality of life, dyspnea, and functional decline. Individuals with ILD experience a high prevalence of anxiety and depression. Recent research has demonstrated pulmonary rehabilitation (PR) alleviates symptoms of anxiety and depression in those with COPD.

RESEARCH QUESTION

What is the influence of PR on symptoms of anxiety and depression in individuals with ILD?

STUDY DESIGN

We conducted a PRISMA-2020-compliant systematic review of randomized controlled trials (RCTs) investigating PR's effect on anxiety and depression in patients with ILD. We searched MEDLINE, EMBASE, Cochrane, and PsycINFO from inception until April 3, 2023. A narrative synthesis was conducted where a quantitative approach was not feasible.

RESULTS

Five RCTs (n = 281) were included. Idiopathic pulmonary fibrosis (IPF) was the most common type of ILD (k = 3). One study reported clinically-significant improvements in symptoms of anxiety among patients with IPF, and two studies for symptoms of depression among patients with sarcoidosis. Dropout rates were similar between intervention and control groups. All studies were at a high risk of bias.

INTERPRETATION

Pulmonary rehabilitation is not detrimental to anxiety or depression for patients with ILD, and may improve symptoms of anxiety in IPF and depression in sarcoidosis. However, no conclusion can be drawn from available evidence, which is limited by heterogeneous populations/interventions, sample sizes and unexpectedly low prevalences of clinically-significant anxiety or depression. Further adequately powered RCTs that focus on anxiety and depressive symptoms as primary outcomes are needed.

Holistic management of patients with progressive pulmonary fibrosis

Progressive pulmonary fibrosis (PF) is a complex interstitial lung disease that impacts substantially on patients' daily lives, requiring personalised and integrated care. We summarise the main needs of patients with PF and their caregivers, and suggest a supportive care approach. Individualised care, education, emotional and psychological support, specialised treatments, and better access to information and resources are necessary. Management should start at diagnosis, be tailored to the patient's needs, and consider end-of-life care. Pharmacological and non-pharmacological interventions should be individualised, including oxygen therapy and pulmonary rehabilitation, with digital healthcare utilised as appropriate. Further research is needed to address technical issues related to oxygen delivery and digital healthcare.

Educational aims

To identify the main needs of patients with PF and their caregivers.To describe the components of a comprehensive approach to a supportive care programme for patients with PF.To identify further areas of research to address technical issues related to the management of patients with PF.

Treatable traits: a comprehensive precision medicine approach in interstitial lung disease

Interstitial lung disease (ILD) is a diverse group of inflammatory and fibrotic lung conditions causing significant morbidity and mortality. A multitude of factors beyond the lungs influence symptoms, health-related quality of life, disease progression and survival in patients with ILD. Despite an increasing emphasis on multidisciplinary management in ILD, the absence of a framework for assessment and delivery of comprehensive patient care poses challenges in clinical practice. The treatable traits approach is a precision medicine care model that operates on the premise of individualised multidimensional assessment for distinct traits that can be targeted by specific interventions. The potential utility of this approach has been described in airway diseases, but has not been adequately considered in ILD. Given the similar disease heterogeneity and complexity between ILD and airway diseases, we explore the concept and potential application of the treatable traits approach in ILD. A framework of aetiological, pulmonary, extrapulmonary and behavioural and lifestyle treatable traits relevant to clinical care and outcomes for patients with ILD is proposed. We further describe key research directions to evaluate the application of the treatable traits approach towards advancing patient care and health outcomes in ILD.

Experiences of UK-based adult transition services for interstitial lung disease in childhood: "There's a lot less cushioning"

Interstitial lung disease in childhood (chILD) is rare and no longer purely a childhood issue as many survive into adulthood, and so have to transition from pediatric to adult healthcare services. Transition is a significant life event that has the potential to impact on physical and mental health outcomes. The European Respiratory Society (ERS) statement on chILD transition highlighted the lack of standardised transition services for chILD transition resulting in a haphazard process. This qualitative study explores how young people and parents in the United Kingdom experienced transition from paediatric to adult healthcare services for chILD. Participants (n = 7) were recruited from chILD patient organisations and online communities. We focused on the experience of transition exploring if there were any information packs or support provided for the transition. Such support may be generic, such as "Ready Steady Go" which provides a systematic approach to transition and disease-specific literature. These latter have not been developed for ILD. Data were analysed by constructivist grounded theory. We present a lived experience of transition with themes of lack of transition preparation and planning, challenges of adapting to adult services, and a changing healthcare scene. Due to the complexity of chILD, parents discussed their need to remain, in part, as an advocate for the young person. Respondents provided recommendations for how transition could be improved along with tips for young people who are new to the transition process, which include educating oneself about the condition, learning medical terminology, and reaching out for support.

Psychiatric and general health effects of COVID-19 pandemic on children with chronic lung disease and parents' coping styles

BACKGROUND

We aim to assess the anxiety and depressive symptoms related to the COVID-19 pandemic in children with chronic lung disease and their parents and also to evaluate parents' coping strategies.

METHODS

Parents of children aged 4-18 years, with chronic lung disease (study group n = 113) and healthy control (n = 108) were enrolled in the study. General Health Questionnaire-12, specific COVID-19 related anxiety questions, The Coping Orientation to Problems Experienced inventory, coronavirus-related psychiatric symptom scale in children-parental form were used to analyze the psychiatric effects of COVID-19. Parents were also asked about how online education affected their family life and children. All data were compared between children/parents in the study and control groups. Risk factors related with anxiety scores of children were also analyzed.

RESULTS

Talking about the pandemic, concern about coronavirus transmission, taking precaution to prevent coronavirus transmission, making pressure to protect from COVID-19 were significantly higher in parents within the study group (p < .05). Parents in the study group used more problem-focused coping than parents in the control group (p = .003). Anxiety symptoms score was higher in children of the study group (p = .007). Parents in the study group found online education more useful than parents in the control group.

CONCLUSION

Children with chronic lung diseases and their parents have more anxiety due to COVID-19 pandemic and these parents use more mature coping strategies to manage the stress of the pandemic. Longitudinal and larger studies should be done in all aspects of online education in children with chronic lung diseases.
