Sociodemographic and Clinical Variables Related to the Overburden of the Informal Caregivers of Patients Hospitalized for Chronic Obstructive Pulmonary Disease Exacerbations

BreathCarer: Informal carers of patients with chronic breathlessness: a mixed-methods systematic review of burden, needs, coping, and support interventions

BACKGROUND

Breathlessness is a common symptom in chronic and advanced diseases, and it poses a significant burden to patients and to their informal carers. They play a crucial role in sustainable care for patients living with breathlessness, but their challenges and needs are often neglected.

OBJECTIVE

To provide a systematic overview of the literature on the burden, needs, coping and use of healthcare and social services by carers of patients suffering from chronic breathlessness due to any life-limiting disease.

DESIGN

A mixed-methods systematic review (PROSPERO CRD42022312989).

DATA SOURCES

Medline, CENTRAL, PsycINFO, and CINAHL were searched and complemented with forward and backward searches and expert consultation.

REVIEW METHODS

The mixed-methods review included any study on burden, needs and coping among carers of patients with breathlessness published from the inception of the databases until July 2023. A narrative analysis of the quantitative results and a pragmatic meta-aggregation of the qualitative findings were performed, followed by a mixed-methods convergent segregated approach.

FINDINGS

A total of 53 studies with 4,849 carers were included. Breathlessness is highly burdensome for carers who live with and care for patients or for those who do not live with the patients and care for them. Breathlessness is a significant risk factor for high carers' burden, contributing to deteriorating physical and mental health among carers and creating an urgent need for external support. A major challenge is the sense of being trapped in a state of constant alertness and anxiety, centred around managing the patient's breathlessness. Carers bear substantial emotional burden due to uncertainty, sleep disturbances, and social isolation, which leads to severe psychological distress. Their unmet needs for professional guidance, self-management strategies, and social interaction are high. While supportive interventions, such as specialized services and multidisciplinary approaches, can alleviate some of the burden, there remains a lack of targeted interventions specifically designed for carers.

CONCLUSIONS

This review highlights the substantial burden associated with caring for patients with chronic breathlessness, the unmet needs of carers and the lack of supportive care structures, leaving them with little option but to accept the situation.

Burden, coping and resilience among caregivers for patients with chronic obstructive pulmonary disease: An integrative review

AIM

This study aims to synthesise quantitative and qualitative evidence to comprehensively examine the burden of family caregivers of chronic obstructive pulmonary disease patients and to understand their coping strategies and related resilience factors.

BACKGROUND

Long-term chronic obstructive pulmonary disease care causes heavy psychological and physical burden to caregivers, which is related to the coping strategies used. Resilience is a protective factor originating within the individual and has become a concept related to illness, health and care.

DESIGN

An integrative review.

METHODS

Relevant literature was comprehensively searched from China Biology Medicine, China National Knowledge Infrastructure, Wan Fang, PubMed, Embase, Web of Science and Ovid databases from the establishment of the database till January 2023, and the quality of the selected articles was evaluated. Reporting was done according to a PRISMA checklist.

FINDINGS

The burden of family caregivers with chronic obstructive pulmonary disease includes poor health, worry and fear, anticipatory loss and uncertainty, relationship tensions and disagreements, loss of identity and social isolation, lack of supportive knowledge and financial burden. Family caregivers used problem-centred coping, emotion-centred coping, avoidance coping, social support and dyadic coping with their patients to manage their burdens. The factors chronic obstructive pulmonary disease associated with a caregiver's resilience included a higher level of knowledge, social and familial support, a close relationship with patients, a caregiver's sense of responsibility, the patient's high self-efficacy, etc. CONCLUSIONS: The findings show that caregivers of chronic obstructive pulmonary disease patients face multiple burdens, adapt through different coping styles and have different psychological consequences, while coping style and mental health status also affect the magnitude of burden.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

The findings informed health professionals about personalised chronic obstructive pulmonary disease home care interventions to reduce caregiver burden, effectively manage illness and maintain family intimacy.

NO PATIENT OR PUBLIC CONTRIBUTION

No patients, families, service providers or members of the public were involved in this study.

Caregiver Burden in Pulmonary Patients

Caregiving has become an increasingly important medical and social issue in recent decades. We performed a cross-sectional study on pulmonary patients and accompanying informal caregivers who were hospitalized in the chest disease ward of a tertiary center in Turkey between January 2020 and April 2021. Informal caregivers were asked to complete the Zarit Caregiver Burden Interview. A total of 141 inpatients (39% female, mean age: 76.8 ± 10.2 years) and their informal caregivers (77% female, mean age: 54 ± 11.9 years) were evaluated. The caregivers were classified as light to medium burden (group 1, burden score ≤40) and medium to heavy burden (group 2, burden score >40). The mean burden score was 35.7 ± 13.3 points. The number of female caregivers was higher in group 2 (p = 0.025). There was a positive correlation between the burden score and female gender (p = 0.002) and the number of chronic diseases of caregivers (p = 0.020). Statistical analysis revealed a negative correlation between the burden score and the level of education (r = > -0.174, p = 0.040). Caregiver burden is related to the characteristics of the caregiver rather than those of the patient being cared for. Female caregivers with lower education and more than one chronic disease perceive a higher caregiver burden.

Nonpharmacological management of psychological distress in people with COPD

Psychological distress is prevalent in people with COPD and relates to a worse course of disease. It often remains unrecognised and untreated, intensifying the burden on patients, carers and healthcare systems. Nonpharmacological management strategies have been suggested as important elements to manage psychological distress in COPD. Therefore, this review presents instruments for detecting psychological distress in COPD and provides an overview of available nonpharmacological management strategies together with available scientific evidence for their presumed benefits in COPD. Several instruments are available for detecting psychological distress in COPD, including simple questions, questionnaires and clinical diagnostic interviews, but their implementation in clinical practice is limited and heterogeneous. Moreover, various nonpharmacological management options are available for COPD, ranging from specific cognitive behavioural therapy (CBT) to multi-component pulmonary rehabilitation (PR) programmes. These interventions vary substantially in their specific content, intensity and duration across studies. Similarly, available evidence regarding their efficacy varies significantly, with the strongest evidence currently for CBT or PR. Further randomised controlled trials are needed with larger, culturally diverse samples and long-term follow-ups. Moreover, effective nonpharmacological interventions should be implemented more in the clinical routine. Respective barriers for patients, caregivers, clinicians, healthcare systems and research need to be overcome.

Outcomes associated with comorbid anxiety and depression among patients with stable COPD: A patient registry study in China

BACKGROUND

Anxiety and depression are common among patients with chronic obstructive pulmonary disease (COPD), but the associations between psychiatric symptoms and specific COPD outcomes are uncertain.

METHODS

Associations of psychiatric symptoms (anxiety and depression) and COPD outcomes (COPD Assessment Test (CAT), modified Medical Research Council dyspnea scale (mMRC), number of acute exacerbations and percentage predicted forced expiratory volume in 1 second (FEV₁% predicted)) sets were performed by canonical correlation analysis in 876 patients with COPD.

RESULTS

In primary analysis, we discovered a statistically significant relationship between symptoms of anxiety/depression and COPD outcomes sets (1 - Λ = 0.11; P < .001). Symptoms of anxiety/depression and four COPD outcomes sets shared 11 % of variance. CAT was the main driver of the relationship (r_s = -0.930; r_s² = 0.8649) followed by mMRC (r_s = -0.632; r_s² = 0.3994) and exacerbation history (r_s = -0.478; r_s² = 0.2285); FEV₁% predicted did't make a significant contribution to the relationship (r_s = 0.134; r_s² = 0.018). In secondary analysis, women were associated with a stronger correlation based on the shared variance between psychiatric symptoms and COPD outcomes sets (17.4 %) than men (9.8 %).

LIMITATIONS

Some confounding factors such as education level, income, didn't be included. There were considerably fewer women enrolled in this study than men.

CONCLUSION

Psychiatric symptoms were associated with COPD subjective outcomes, and more related to COPD outcomes in women.
