Quality of life and burden in carers for persons with Chronic Obstructive Pulmonary Disease receiving oxygen therapy

Construct validity and reliability of the Informal Caregiver Burden Assessment Questionnaire (QASCI) in caregivers of patients with COPD

INTRODUCTION

COPD often leads to loss of independence in daily activities which may increase the dependency on the informal caregiver, resulting in caregiving burden. Several instruments have been used to assess caregiving burden in COPD; however, their measurement properties have been poorly investigated in this population. This study assessed the construct validity and reliability of the Informal Caregiver Burden Assessment Questionnaire (QASCI) in informal caregivers of patients with COPD.

METHODS

Participants completed the QASCI (higher scores indicate higher burden) and the following questionnaires to assess construct validity: Zarit Burden Interview (ZBI), Hospital Anxiety and Depression Scale (HADS) and World Health Organization Quality of Life Instrument - Short Form (WHOQOL-Bref). QASCI was completed again one week later to assess test-retest reliability. Statistical analyses included: Pearson's (r) or Spearman's (ρ) correlations (construct validity); Cronbach's α (internal consistency); Intraclass Correlation Coefficient (ICC_2,1, test-retest reliability) and Standard Error of Measurement (SEM), Minimal Detectable Change (MDC₉₅) and Bland and Altman 95% Limits of Agreement (LoA).

RESULTS

Fifty caregivers (62.7 ± 9.8 years, 88% female; patients' FEV₁ = 45.2 ± 21.3%predicted) participated. QASCI mean score was 28.5 ± 19.8 (moderate burden). QASCI was positively correlated with ZBI (r = 0.908; p < 0.01), HADS anxiety (r = 0.613; p < 0.01) and depression (ρ = 0.634; <0.01) and negatively correlated with WHOQOL-Bref (-0.476 to -0.739) (all p < 0.01). Cronbach's α was 0.793 for the QASCI total score (subscales: 0.747-0.932). The ICC_2,1 was 0.924, SEM 2.8 and MDC₉₅ 7.8, and the LoA were -18.3 to 11.1.

CONCLUSIONS

The QASCI seems to be a promising measure to assess burden levels associated with informal caregiving in COPD.

Feasibility of telepsychology support for patients with advanced cardiorespiratory diseases and their caregivers

Objective

The aim of this study was to test the feasibility of telepsychology support for patients with severe cardiorespiratory disease and their caregivers. A secondary objective was to explore pre-post relationships between patients' and caregivers' clinical measures.

Methods

A telehealth program incorporating telepsychology support, i.e., an “on-demand” phone service with a psychologist, was provided to consecutive cardiorespiratory patients at discharge from inpatient rehabilitation and to their caregivers. At the start and end of the 1-year program, participants were interviewed “face-to-face,” and their anxiety/depression level, patients' quality of life (MRF-28, SF-36, and MQOL), and caregivers' (n = 18) family strain (FSQ) and needs (CNA) were assessed: we analyzed the correlations and evaluated customer satisfaction.

Results

Of 80 eligible individuals, 40 took part in this study: 22 patients (FVC = 39 ± 14%; EF = 39 ± 13%) and 18 caregivers. Eleven (28%, 6 patients and 5 caregivers) requested tele-psychological support, resulting in 51 consultations focused on anxiety, difficulty in patient management, worry about the patient's emotional state, and need for emotional support; 3 participants underwent a tailored psychotherapy program. All participants expressed high satisfaction with the service. At enrolment, anxiety was less evident in patients (73% men) than in caregivers, while depressive symptoms were more evident (6.5 ± 3.1), and correlated with MRF-28 and MQOL. Caregivers' (94% women) FSQ showed a “strongly recommended” need for support; at enrolment, high levels of anxiety/depression were correlated with high FSQ (for both, p < 0.05); depressive symptoms correlated negatively with age (p = 0.025) and positively with emotional needs (p = 0.025); anxiety was positively correlated with education level (p = 0.048). At follow-up, patients' perception of support (n = 13/22) tended to increase (p = 0.089), while caregivers' strain (n = 10/18) tended to decline (to within the “range of attention”). At enrolment, caregivers' anxiety/depression and strain correlated with patients' quality of life (for both; p < 0.05). At follow-up, caregivers' strain correlated with patients' quality of life (p = 0.028) and cognitive performance (p = 0.048).

Conclusion

Telepsychology support associated with a telehealth service is feasible and satisfying for both participants and psychological management. A suitable support program can benefit both patients and caregivers, particularly those at higher risk of depressive symptoms (younger caregivers) and anxiety (all caregivers).

Anticipatory Burden in Adult-Child Caregivers: A Concept Analysis

This study aims to analyze the concept of anticipatory burden in adult-child caregivers. A systematic literature review was performed using four databases, Pubmed, CINAHL, PsycINFO and Medline, with the keywords of “anticipatory burden” and “anticipated burden”. Simplified Wilson’s classic concept analysis modified by Walker and Avant was employed to identify the attributes, antecedents and consequences of anticipatory burden in the adult-child caregivers. Eighteen articles were analyzed. Attributes of anticipatory burden in adult-child caregivers were found to be: (1) subjective burden, (2) anticipation, (3) overestimation, (4) inability, and (5) family relationship. Antecedents were identified as: (1) potential care recipients, (2) caregiving willingness, and (3) a lack of resources. Consequences included: (1) prediction of caregiving willingness, (2) impacts on caregivers’ health, (3) intervention promotion, and (4) behavioral changes. As the adult-child caregiver is one of the main types of family caregivers for the fast-growing aging population, it is important to understand the attributes, antecedents, and consequences of their anticipatory burden. Based on the results of this study, resources such as intervention, policy, and counseling services are recommended to help adult-child caregivers lower their anticipatory burden and get better prepared for providing family care.

Predictors of Successful Oxygen Weaning in Older Patients Undergoing Pulmonary Rehabilitation

OBJECTIVES

To identify clinical and/or functional variables predictive of successful oxygen-weaning among older patients affected by respiratory insufficiency undergoing pulmonary rehabilitation.

DESIGN

Retrospective study.

SETTING AND PARTICIPANTS

Data are from 154 patients aged 65 years and older (mean age = 78.1 years; female 50.6%) admitted to a pulmonary rehabilitation unit to follow an in-patient program. Patients must require oxygen therapy at admission.

METHODS

All patients performed the 6-Minute Walking Test at admission and before discharge as well as a spirometry at a steady state. Multivariate logistic regressions were performed to identify positive and negative predictors of successful oxygen weaning.

RESULTS

Successful oxygen weaning was obtained in 47 participants (30.5%). The restrictive pattern was associated with a 4-fold likelihood of successful oxygen weaning at the end of the rehabilitation program compared with the obstructive one. A positive association was also found for arterial oxygenation index (PaO₂/FiO₂ ratio) at baseline. A decreased likelihood of successful oxygen weaning was reported for the subjective dyspnea perception score at exertion evaluated with a modified Borg scale.

CONCLUSIONS AND IMPLICATIONS

The restrictive pattern, PaO₂/FiO₂ ratio, and modified Borg dyspnea scale score under exertion were significantly associated with successful oxygen-weaning. The identified predictors may support clinicians at precociously identifying patients who may not require oxygen therapy after discharge. Therefore, these findings would make it possible for clinicians to better tailor the rehabilitation program.

Association of physical and psychological health status between chronic obstructive pulmonary disease patients and their family caregivers

We performed this cross-sectional study with 72 chronic obstructive pulmonary disease (COPD) patients and their family caregivers to analyze relationship of physical and psychological health status between COPD patients and caregivers. Most caregivers were female (100%). Caregiver depression and burden were significantly associated with caregiving hours. In path analysis, the higher the patient's social support, the higher the patient's self-efficacy. The higher the patient's self-efficacy, the lower the care burden of the caregiver. Based on our results, there was a significant correlation of physical and psychological factors between patients and family caregivers.

Caregivers' Perspectives on the Use of Long-Term Oxygen Therapy for the Treatment of Refractory Breathlessness: A Qualitative Study

CONTEXT

Despite limited clinical evidence, long-term oxygen therapy (LTOT) is used for the management of refractory breathlessness in people with life-limiting illnesses who are not necessarily hypoxemic.

OBJECTIVES

The aim of this study was to understand caregiver factors associated with caring for someone with LTOT from the perspectives and experiences of caregivers themselves.

METHODS

The qualitative study used semistructured interviews. The study was conducted in two states in Australia. Participants (n = 20) were self-nominated caregivers of people receiving LTOT for refractory breathlessness in the palliative setting.

RESULTS

Data analyses established one overarching theme titled: "Oxygen giveth (something to help caregivers relieve breathlessness) and oxygen taketh away (from patients who lose some autonomy)." The theme captured caregivers' feelings of extreme distress in response to witnessing refractory breathlessness, and oxygen fulfilling several critical and beneficial roles in this context. In parallel, caregivers also explicitly and implicitly articulated several downsides to the use of LTOT.

CONCLUSION

Caregivers find caring for someone with refractory breathlessness extremely distressing. The benefits of LTOT are often overestimated, whereas its potential harms are underestimated. As significant stakeholders of people receiving LTOT, caregivers should be provided with opportunities to collaborate with clinicians in evidence-based decision making, efforts should be made to provide them with information and education about the most effective pharmacological and nonpharmacological strategies to manage refractory breathlessness in a palliative care setting including the appropriate use of LTOT to enable them to do so.

Acidente vascular encefálico: características do paciente e qualidade de vida de cuidadores

RESUMO Objetivo: investigar a associação entre os domínios da qualidade de vida relacionada à saúde dos cuidadores familiares e as características sociodemográficas dos indivíduos com sequelas de AVE. Método: pesquisa descritiva, transversal, quantitativa, realizada com 136 cuidadores familiares de indivíduos com sequelas de AVE, mediante entrevistas domiciliárias de abril a junho de 2013. Resultados: verificou-se que os cuidadores de indivíduos com idade inferior a 65 anos, casados, com dez a 12 anos de escolaridade, apresentaram maiores escores, respectivamente nos domínios 'Aspectos sociais', 'Aspectos emocionais' e 'Saúde mental'. Entretanto, os cuidadores de pacientes com maior grau de incapacidade obtiveram menor escore no domínio 'Saúde mental'. Conclusão: os resultados permitem refletir acerca da necessidade de inserir os cuidadores familiares de indivíduos com sequelas de AVE no planejamento de cuidados prestados pelos profissionais de saúde.
