Reactions to caregiving in frailty research

Effectiveness of interventions for informal caregivers of community-dwelling frail older adults: A systematic review and meta-analysis

AIM

Systematic reviews on interventions for informal caregivers of community-dwelling frail older adults were published over a decade ago and they mistook frailty for other severe age-related conditions like disability and dementia. Therefore, this study aimed to systematically synthesize these interventions supporting these caregivers identified by an acknowledged frailty assessment instrument and to examine their effectiveness on caregiver-related outcomes.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Fourteen electronic databases, grey literature and reference lists were systematically searched for randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) from inception to November 3, 2023.

METHODS

Methodology quality and risk of bias were assessed. Data were meta-analysed using the Comprehensive Meta-Analysis, version 3.0. Studies and outcomes unsuitable for meta-analysis were summarized by narrative syntheses.

RESULTS

Four studies consisting of three RCTs and one NRCT were included involving 350 participants. Interventions for caregivers of frail older adults included multicomponent interventions (n = 3) and education intervention (n = 1). Interventions had a moderate effect on reducing depression and showed nonsignificant effects on caregiver burden, caregiving time or quality of life (QoL). The PEDro scores for RCTs ranged from 6 to 8, indicating good methodologic quality, but were all judged as high risk of bias. The NRCT reported all methodologic aspects and was at low risk of bias.

CONCLUSIONS

Few studies focus on interventions targeting caregivers of frail older adults, and their effectiveness may vary by outcomes. This review suggested the potential benefits of these interventions in reducing caregivers' depression.

IMPACT

The differential effectiveness by outcomes and high risk of bias of studies implicate that more rigorous studies are warranted.

Factors associated with health-related quality of life and burden on relatives of older people with multi-morbidity: a dyadic data study

BACKGROUND

This study aimed to identify factors associated with health-related quality of life (HRQoL) and the burden on the relatives of older people with multi-morbidity.

METHODS

A secondary analysis of baseline data from 296 dyads, including older patients with multimorbidity and their relatives, which were previously collected in a randomized study. The analysis was conducted to select correlated independent variables to enter a final linear regression analysis of two models with different endpoints: the relatives' HRQoL (EQ5D index) and burden (COPE index: Negative impact scale).

RESULTS

Sixteen variables correlated with the relatives' HRQoL, and 15 with the relatives' burden. Both the HRQoL and burden correlated with both patient and relative variables. A high HRQoL was associated with relatives' working/studying. A high burden was associated with caring for an older person with changed behaviour. A low burden was associated with the relatives' high scores on positive values of caring, quality of support and HRQoL.

CONCLUSION

Older persons and their relatives should be considered as a unit in the development of support of older people in order to increase the health and quality of life of both groups. To support and protect relatives from a high burden, potential measures could include improving the relative's HRQoL and strengthening their ability to find positive values in care and strengthening reliable and good support from others. The relatives' HRQoL explained the variation in the burden. However, the burden did not explain the variation in the HRQoL, which suggests that the relatives' HRQoL is not so readily affected by their burden, whereas the relatives' HRQoL can influence their burden. The variables used in the regression analyses where chosen to reflect important aspects of the relatives' and older persons' situations. The final models explained 38% of the variation in the relatives' burden but only 10% of the variation in their HRQoL. This could be important to consider when choosing outcome assessments in future studies.

Mental health and reactions to caregiving among next of kin of older people (65+) with multi-morbidity discharged home after hospitalization

BACKGROUND

Older people with multi-morbidity are major users of healthcare and are often discharged from hospital with ongoing care needs. This care is frequently provided by informal caregivers and the time immediately after discharge is challenging for caregivers with new and/or additional tasks, resulting in anxiety and stress.

AIM

This study aimed to describe mental health, with particular reference to anxiety and depression and reactions to caregiving, and to investigate any associations between the two, in next of kin of older people with multi-morbidity after hospitalisation. It also aimed to explore the association between the demographic characteristics of the study group and mental health and reactions to caregiving.

METHODS

This was a cross-sectional questionnaire study using the Hospital Anxiety and Depression Scale and the Caregiver Reaction Assessment. The study group consisted of 345 next of kin of older people (65+) with multi-morbidity discharged home from 13 medical wards in Sweden. Data were analysed using descriptive and analytical statistics. To identify whether reactions to caregiving and next of kin characteristics were associated with anxiety and depression, a univariate logistic regression analysis was performed.

RESULTS

More than one quarter of respondents showed severe anxiety and nearly one in 10 had severe depressive symptoms. The frequencies of anxiety and depression increased significantly with increased negative reactions to caregiving and decreased significantly with positive reactions to caregiving. Regarding caregiving reactions, the scores were highest for the positive domain Caregiver esteem, followed by the negative domain Impact on health. Women scored significantly higher than men on Impact on health and spouses scored highest for Impact on schedule and Caregiver esteem.

CONCLUSIONS

Nurses and other healthcare professionals may need to provide additional support to informal caregivers before and after discharging older people with significant care needs from hospital. This might include person-centred information, education and training.

Frailty differences in older adults' use of informal and formal care

OBJECTIVES

This study examines different combinations of informal and formal care use of older adults and investigates whether these combinations differ in terms of need for care (physical and psychological frailty) and enabling factors for informal and formal care use (social and environmental frailty).

METHODS

Using cross-sectional data from the Belgian Ageing Studies (survey, N = 38,066 community-dwelling older adults), Latent Class Analysis (LCA) is used to identify combinations of informal and formal care use. Bivariate analyses are used to explore the relationship between the different combinations of care use and frailty.

RESULTS

Latent Class Analysis (LCA) identified 8 different types of care use, which vary in combinations of informal and formal caregivers. Older adults who are more likely to combine care from family and care from all types of formal caregivers are more physically, psychologically and environmentally frail than expected. Older adults who are more likely to receive care only from nuclear family, or only from formal caregivers are more socially frail than expected.

CONCLUSIONS

Older adults with a higher need for care are more likely to receive care from different types of informal and formal caregivers. High environmental frailty and low social frailty are related with the use of care from different types of informal and formal caregivers. This study confirms that informal care can act as substitute for formal care. However, this substitute relationship becomes a complementary relationship in frail older adults. Policymakers should take into account that frailty in older adults affects the use of informal and formal care.

Relationship between family caregiver burden and physical frailty in older adults without dementia: a systematic review

BACKGROUND

Physical frailty is a prevalent syndrome in older adults that increases vulnerability for a range of adverse outcomes including increased dependency and death. Caregivers of older adults experience significant physical, emotional, and financial burden, which is associated with poor physical and mental health. While it is known that care recipients' dementia is associated with burden, the literature regarding the impact of physical frailty on burden has yet to be synthesized. We conducted a systematic review to assess the state of the evidence regarding the relationship between these two prominent concepts in the geriatric literature.

METHOD

We used a structured search of databases to identify original English-language articles. Two researchers screened the titles and abstracts of all 1202 retrieved studies and then full-text versions of 265 retained studies. Screening was based on a priori inclusion criteria, which included discussion of physical frailty, caregiver burden, and a population of community-dwelling older adults without dementia. Nine included papers underwent data abstraction and critical appraisal using the Cochrane Risk of Bias Tool or the Newcastle-Ottawa Scale (for randomized controlled trials or cross-sectional studies, respectively). Heterogeneity of the included studies precluded meta-analysis.

RESULTS

Five publications had the same author and drew from the same population; these were treated as a single study. Three of our studies were of limited value since they did not include a validated measure of frailty. While caregivers of frail older adults experience burden, the scarce available evidence and lack of studies comparing this population with normative values does not allow conclusions to be drawn about the strength or nature of the relationship. Judging from excluded studies, the term "frailty" is often used without reference to a clear definition or is treated as synonymous with functional impairment or advanced age.

CONCLUSIONS

Our review suggests that caregivers of frail older adults experience burden and that the degree of burden may differ from that of other caregiver populations. The limited evidence does not allow conclusions to be drawn or to inform clinical practice. Further research is needed, given the salience of physical frailty and burden.

Care recipients' physical frailty is independently associated with subjective burden in informal caregivers in the community setting: a cross-sectional study

BACKGROUND

Physical frailty is associated with significant morbidity and mortality in community-dwelling older adults. Burden in informal caregivers of older adults causes significant physical and psychological distress. However, the relationship between these two clinical phenomena has not been extensively studied. This cross-sectional study evaluated the relationship between physical frailty of community-dwelling older adults attending an outpatient geriatric clinic and the subjective burden reported by their informal caregivers.

METHODS

We measured the following characteristics of 45 patient-caregiver dyads attending an outpatient geriatric assessment clinic: Physical frailty using the Fried Frail Scale (FFS); self-reported independence in activities of daily living (ADL) using the Katz Index; clinical diagnosis of dementia; and subjective caregiver burden using the short 12-item version of the Zarit Burden Interview (ZBI). Multivariable linear regression was performed with FFS, Katz Index score, gender, age, and diagnosis of dementia as independent variables, and ZBI score as the dependent variable.

RESULTS

Only physical frailty significantly predicted caregiver burden (β = 8.98 95% confidence interval [CI]: 2.15, 15.82).

CONCLUSIONS

Physical frailty is independently associated with caregiver burden in a population of community-dwelling older adults. Despite limitations related to sample size and lack of data about caregiver characteristics, this study suggests that the relationship between physical frailty and caregiver burden merits further study.

Cardiac autonomic modulation in non-frail, pre-frail and frail elderly women: a pilot study

Frailty has been defined as a geriatric syndrome that results in high vulnerability to health adverse outcomes. This increased vulnerability state results from dysregulation of multiple physiological systems and its complex interactions. Thus, assessment of physiological systems integrity and of its dynamic interactions seems to be useful in the context of frailty management. Heart rate variability (HRV) analysis provides information about autonomic nervous system (ANS) function, which is responsible to control several physiologic functions. This study investigated the cardiac autonomic modulation by HRV analysis in community-dwelling elderly women classified as non-frail, pre-frail and frail. Twenty-three elderly women were assigned to the following groups: non-frail (n = 8), pre-frail (n = 8) and frail (n = 7). HRV assessment was performed through linear and non-linear analysis of cardiac interval variability. It was observed a higher sympathetic and lower parasympathetic modulation in frail when compared with non-frail and pre-frail groups (p < 0.05) as indicated by frequency domain indices. Additionally, frail group had a decreased 2LV % pattern (that reflects parasympathetic modulation) in the symbolic analysis in comparison with non-frail group. These findings suggest that frail elderly women present an autonomic imbalance characterized by a shift towards sympathetic predominance. Thus, monitoring ANS function in the context of frailty management may be an important strategy to prevention, diagnosis and treatment of this syndrome and its consequences.

Using computers to enable self-management of aphasia therapy exercises for word finding: the patient and carer perspective

BACKGROUND

Speech and language therapy (SLT) for aphasia can be difficult to access in the later stages of stroke recovery, despite evidence of continued improvement with sufficient therapeutic intensity. Computerized aphasia therapy has been reported to be useful for independent language practice, providing new opportunities for continued rehabilitation. The success of this option depends on its acceptability to patients and carers.

AIMS

To investigate factors that affect the acceptability of independent home computerized aphasia therapy practice.

METHODS & PROCEDURES

An acceptability study of computerized therapy was carried out alongside a pilot randomized controlled trial of computer aphasia therapy versus usual care for people more than 6 months post-stroke. Following language assessment and computer exercise prescription by a speech and language therapist, participants practised three times a week for 5 months at home with monthly volunteer support. Semi-structured interviews were conducted with 14 participants who received the intervention and ten carers (n = 24). Questions from a topic guide were presented and answered using picture, gesture and written support. Interviews were audio recorded, transcribed verbatim and analysed thematically. Three research SLTs identified and cross-checked themes and subthemes emerging from the data.

OUTCOMES & RESULTS

The key themes that emerged were benefits and disadvantages of computerized aphasia therapy, need for help and support, and comparisons with face-to-face therapy. The independence, flexibility and repetition afforded by the computer was viewed as beneficial and the personalized exercises motivated participants to practise. Participants and carers perceived improvements in word-finding and confidence-talking. Computer practice could cause fatigue and interference with other commitments. Support from carers or volunteers for motivation and technical assistance was seen as important. Although some participants preferred face-to-face therapy, using a computer for independent language practice was perceived to be an acceptable alternative.

CONCLUSIONS & IMPLICATIONS

Independent computerized aphasia therapy is acceptable to stroke survivors. Acceptability can be maximized by tailoring exercises to personal interests of the individual, ensuring access to support and giving consideration to fatigue and life style when recommending practice schedules.

Research on a community-based platform for promoting health and physical fitness in the elderly community

This study aims to assess the acceptability of a fitness testing platform (iFit) for installation in an assisted living community with the aim of promoting fitness and slowing the onset of frailty. The iFit platform develops a means of testing Bureau of Health Promotion mandated health assessment items for the elderly (including flexibility tests, grip strength tests, balance tests, and reaction time tests) and integrates wireless remote sensors in a game-like environment to capture and store subject response data, thus providing individuals in elderly care contexts with a greater awareness of their own physical condition. In this study, we specifically evaluated the users’ intention of using the iFit using a technology acceptance model (TAM). A total of 101 elderly subjects (27 males and 74 females) were recruited. A survey was conducted to measure technology acceptance, to verify that the platform could be used as intended to promote fitness among the elderly. Results indicate that perceived usefulness, perceived ease of use and usage attitude positively impact behavioral intention to use the platform. The iFit platform can offer user-friendly solutions for a community-based fitness care and monitoring of elderly subjects. In summary, iFit was determined by three key drivers and discussed as follows: risk factors among the frail elderly, mechanism for slowing the advance frailty, and technology acceptance and support for promoting physical fitness.

Reactions to caregiving during an intervention targeting frailty in community living older people

Background

The demands and consequences of caregiving are considerable. However, such outcomes are not commonly investigated in the evaluation of interventions targeting frailty. This study aims to explore family carers’ reactions to caregiving during an intervention targeting frailty in community living older people.

Method

A study of carers (n=119) embedded in a 12 month randomised controlled intervention targeting frailty in people 70 years or older, compared to usual care. Reactions to caregiving were measured in the domains of health, finance, self-esteem, family support and daily schedule. Anxiety and depression levels were also evaluated. Carer outcomes were measured at baseline, 6 months and 12 months and at 3 months post frailty intervention.

Results

Carers of frail older people in the intervention group showed a sustained improvement in health scores during the intervention targeting frailty, while health scores for carers of the frail older people in the control group, decreased and therefore their health worsened (F=2.956, p=0.034). The carers of the frail older people in the intervention group reported overall better health (F=5.303, p=0.023) and self-esteem (F=4.158, p=0.044), and co-resident carers reported higher self-esteem (F=4.088, p=0.046). Anxiety levels increased for carers in both intervention and control groups (F=2.819, p=0.04).

Conclusion

The inclusion of carers in trials targeting frail older people may assist in the identification of at-risk carers and facilitate the provision of information and support that will assist them to continue providing care. Further research that explores the features of frailty interventions that impact on the caregiving experience is recommended.

Residential respite care is associated with family carers experiencing financial strain

AIM

Care services for older people are provided with the expectation of supporting carers in their caregiving role. The aim of the study is to investigate the association between the utilisation of care services by older people and the caregiving experience.

METHODS

Cross-sectional design, involving a cohort of family carers (n = 119) of frail older people (≥70 years) enrolled in a clinical trial of frailty treatment in metropolitan Sydney from 2008 to 2011. The caregiving experience was measured in five domains: health, daily schedule, finance, family support and self-esteem (Caregiver Reaction Assessment tool).

RESULTS

Multivariate regression analysis demonstrated an association between the utilisation of residential respite care and financial strain (β = -0.613, P = 0.049), after controlling for functional ability, co-residence and age.

CONCLUSION

There is a need to consider carers' financial barriers and concerns in regards to the utilisation of respite care services.
