Giving Voice to People - Experiences During Mild to Moderate Acute Exacerbations of COPD

Symptom Network and Subgroup Analysis in Patients with Exacerbation of Chronic Obstructive Pulmonary Disease: A Cross-Sectional Study

Purpose

This study aims to construct a contemporaneous symptom network of inpatients with Exacerbation of Chronic Obstructive Pulmonary Disease (ECOPD) based on the symptom cluster, identify core and bridge symptoms, and patient subgroups with different symptom clusters based on individual differences in the intensity of patient symptom experiences.

Patients and Methods

This study used convenience sampling to collect demographic, symptom, auxiliary examination, and prognosis information of 208 inpatients with ECOPD from April 2022 to October 2023. The data underwent exploratory factor analysis (EFA), symptom network analysis, latent class analysis (LCA), Spearman correlation analysis, Wilcoxon signed-rank test, single-factor regression and multiple-factor stepwise regression.

Results

In hospitalized patients with ECOPD, symptom network analysis revealed that loss of appetite was the core symptom, while chest distress was the bridge symptom. Through LCA analysis, two symptom subgroups were identified: a high-symptom group (53.8%) and a low-symptom group (46.2%). This suggests that there is significant heterogeneity in symptom experience among ECOPD individuals. Patients in the high-symptom group had a higher probability of experiencing symptom clusters related to nutrition-sleep.

Conclusion

The combination of symptom network analysis and LCA comprehensively captures the symptom/symptom cluster characteristics and accounts for the heterogeneity of ECOPD patients from both individual and group perspectives. This study identifies core symptoms, bridge symptoms, and symptom subgroups, offering valuable insights for precision symptom management in ECOPD.

Understanding the Gaps in the Reporting of COPD Exacerbations by Patients: A Review

Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with loss of lung function, poor quality of life, loss of exercise capacity, risk of serious cardiovascular events, hospitalization, and death. However, patients underreport exacerbations, and evidence suggests that unreported exacerbations have similar negative health implications for patients as those that are reported. Whilst there is guidance for physicians to identify patients who are at risk of exacerbations, they do not help patients recognise and report them. Newly developed tools, such as the COPD Exacerbation Recognition Tool (CERT) have been designed to achieve this objective. This review focuses on the underreporting of COPD exacerbations by patients, the factors associated with this, the consequences of underreporting, and potential solutions.

Pulmonary rehabilitation and family/friend caregivers: the hidden reciprocal relationship improving outcomes in chronic respiratory diseases

INTRODUCTION

The experiences and needs of living with chronic respiratory diseases (CRD) can be overwhelming. Individuals often rely on informal care for daily assistance and having a family/friend caregiver has been associated with better health outcomes. Nevertheless, family/friend caregivers frequently feel alone and unsupported. Pulmonary rehabilitation (PR) leads to multidimensional benefits across CRD and individuals have suggested improvements for PR. Family/friend caregivers highly support PR in practical and psychosocial ways and have identified this intervention as an opportunity to be supported. This reciprocal relationship between PR and the family/friend caregivers has been scarcely explored and its importance for the management of CRD is poorly understood.

AREAS COVERED

This perspective synthesizes the experiences and needs of living with CRD from the perspective of people with CRD and their family/friend caregivers; and proposes a vision of a reciprocal/symbiotic relationship, through PR, for optimizing care for people with CRD and their caregivers.

EXPERT OPINION

A deeper understanding/recognition of the extensiveness and somewhat overlap of the experiences and unmet needs of individuals with CRD and their family/friend caregivers; and of the reciprocal/symbiotic relationship between PR and the family/friend caregivers might be important to optimizing management and, ultimately, individuals and caregivers' outcomes in CRD.

Development and feasibility of an exercise training program in primary care for patients with COPD experiencing an acute exacerbation

BACKGROUND

Starting rehabilitation soon after an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is crucial to diminish the detrimental effects of this acute event on muscle function. However, uptake in outpatient pulmonary rehabilitation is low.

OBJECTIVES

To design and test a feasible, acceptable and accessible exercise training program (ETP) in primary care for patients experiencing an AECOPD.

DESIGN

(1) A literature review and qualitative study to develop an ETP and (2) A feasibility study of the ETP implemented in primary care.

METHODS

(1) The development of the ETP proceeded in several phases with input from different stakeholders through focus group discussions. (2) Patients experiencing a moderate or severe AECOPD were included and followed the ETP for two weeks with a physiotherapist in primary care. Interviews with the participants took place and patients were given the choice to complete the eight-week program.

RESULTS

(1) Six discussion sessions took place. The ETP contained a flexible set of progressively more difficult exercises applicable in a primary care practice. (2) Eight patients experiencing a moderate (n = 1) or severe (n = 7) AECOPD were included. Patients started the first physiotherapy session 5 (2-6) days after the start of their symptoms or hospital discharge. Seven patients wanted to complete the ETP.

CONCLUSIONS

An ETP in primary care is feasible, acceptable and accessible for patients experiencing a moderate or severe AECOPD, and for physiotherapists. The effectiveness of this ETP on muscle function and physical activity is currently under investigation in a RCT. CONTRIBUTION OF THE PAPER.

Integrating palliative care education in pulmonary rehabilitation: a randomized controlled study protocol

BACKGROUND

Palliative care addresses multiple unmet needs of people with chronic obstructive pulmonary disease (COPD) or interstitial lung diseases (ILD) and their family and/or friend caregivers, but it remains highly underused. Pulmonary rehabilitation (PR) may provide a key opportunity to introduce palliative care. We aim to explore the effects of palliative care education as part of PR on knowledge about this field in people with COPD or ILD and their family and/or friend caregivers.

METHODS

A randomized controlled study will compare PR with palliative care education (experimental) with traditional PR (control) in people with COPD or ILD and their family and/or friend caregivers. Family and/or friend caregivers will be invited to take part in education and psychosocial support sessions. In addition to the usual educational content, the experimental group will have a session on palliative care, a "Peer-to-peer session", two "Get-apart sessions" and online sessions. The "Peer-to-peer session" and the "Get-apart sessions" will be discussions about topics suggested by participants. The "Get-apart sessions" will be dedicated to people with COPD or ILD apart from their family and/or friend caregivers and vice versa. The online sessions will be zoom meetings to discuss any health-related issues raised by participants, at a flexible time. A mixed-methods approach will be used to evaluate the outcomes. The primary outcome will be knowledge about palliative care. Secondary outcomes will include attitude towards palliative care referral, symptoms, disease impact, health-related quality of life, needs, knowledge about the disease, burden of providing care, adherence, adverse events and referral to a specialist palliative care team. Quantitative and qualitative data will be collected at baseline and end of PR. At 6-months post-PR, only patient-reported outcomes will be collected. For the primary outcome, time*group interaction will be analyzed with mixed analysis of variance.

DISCUSSION

This study aims to demonstrate the impact of integrating palliative care into the PR education program.

Re-exacerbation within 30 days of discharge is associated with poor prognosis in the following year among patients hospitalised with exacerbation of chronic obstructive pulmonary disease: a clinical cohort study

BACKGROUND

Exacerbation of chronic obstructive pulmonary disease (ECOPD) is a complex phenomenon, with marked heterogeneity in the aetiology, pathophysiology and clinical manifestations. This study aimed to evaluate the clinical characteristics and long-term outcomes of patients with 30-day exacerbation among those hospitalised with ECOPD in China.

METHODS

Data from the Acute Exacerbations of Chronic Obstructive Pulmonary Disease Inpatient Registry were used in this study. The patients were divided into re-event and non-event groups based on the incidence of re-exacerbation within 30 days of discharge. Exacerbation, severe exacerbation and all-cause readmissions in the following 12 months were the outcomes of interest. The cumulative incidence rates and incidence densities were calculated. Multivariate hazard function models were used to determine the association between 30-day re-exacerbation and the long-term outcomes after accounting for the competing risk of death.

RESULTS

Re-exacerbation within 30 days of discharge was observed in 4.9% (n=242) of the patients (n=4963). The cumulative incidence rates and incidence densities of exacerbation, severe exacerbation and all-cause readmissions in the event group were significantly higher than those in the non-event group. After adjustment, re-exacerbation within 30 days of discharge was associated with increased risks of exacerbation, severe exacerbation and all-cause readmissions in the following 12 months (adjusted HR: 3.85 (95% CI: 3.09 to 4.80), 3.46 (2.66 to 4.50) and 3.28 (2.52 to 4.25) accordingly).

CONCLUSION

Re-exacerbation of COPD within 30 days of discharge is a significant predictor of long-term prognosis. In clinical practice, short-term re-exacerbation is a significant clinical phenotype of ECOPD that requires careful management at the earliest.
