Dementia caregiver burgen in a brasilian sample: Association to neuropsychiatric symptoms

Self-Assessment Instruments for Supporting Family Caregivers: An Integrative Review

Family caregivers take on a variety of tasks when caring for relatives in need of care. Depending on the situation and the intensity of care, they may experience multidimensional burdens, such as physical, psychological, social, or financial stress. The aim of the present study was to identify and appraise self-assessment instruments (SAIs) that capture the dimensions of family caregivers' burdens and that support family caregivers in easily identifying their caregiving role, activities, burden, and needs. We performed an integrative review with a broad-based strategy. A literature search was conducted on PubMed, Google Scholar, Google, and mobile app stores in March 2020. After screening the records based on the eligibility criteria, we appraised the tools we found for their usefulness for family care and nursing practice. From a total of 2654 hits, 45 suitable SAIs from 274 records were identified and analyzed in this way. Finally, nine SAIs were identified and analyzed in detail based on further criteria such as their psychometric properties, advantages, and disadvantages. They are presented in multi-page vignettes with additional information for healthcare professionals. These SAIs have proven useful in assessing the dimensions of caregiver burden and can be recommended for application in family care and nursing practice.

How patients with dementia influence caregiver burden using the Dementia Assessment Sheet for Community-based Integrated Care System-21 items (DASC-21) and Zarit Caregiver Burden Interview (ZBI)

BACKGROUND

Dementia is a disease that is frequently associated with significant caregiving burden. The present study was conducted on patients with dementia in order to investigate the causes of caregiver burden using the Dementia Assessment Sheet for Community-based Integrated Care System-21 items (DASC-21) and Zarit Caregiver Burden Interview (ZBI).

METHODS

The study subjects consisted of 206 elderly patients (mean age: 80.9 ± 5.9 years) with dementia in an outpatient clinic. Current age, gender, type of dementia, Mini-Mental State Examination, Hasegawa Dementia Scale-Revised, Clinical Dementia Rating (CDR), Geriatric Depression Scale (GDS) and the DASC-21 were investigated. Caregiver burden was assessed by using the ZBI. Behavioural and Psychological Symptom of Dementia (BPSD) were evaluated by using the Neuropsychiatric Inventory (NPI). Simple regression analysis for the ZBI was performed with respective risk factors as independent variables. Thereafter, multiple regression analysis was performed.

RESULTS

The mean ZBI score was 28.0 ± 18.1, whereas mean DASC-21 score was 44.4 ± 13.2. Simple regression analysis for the ZBI was performed with respective risk factors as independent variables. The DASC-21 (P < 0.001), CDR (P < 0.001), NPI (P < 0.001), and GDS (P = 0.034) were significantly associated with the ZBI. For each item of the DASC-21, Memory (P < 0.001), Orientation (P < 0.001), Solving issues/Common sense (P < 0.001), Instrumental activities of daily living (IADL) outside the home (P < 0.001), IADL inside the home (P < 0.001), Physical ADL① (P < 0.001) and Physical ADL② (P = 0.014) were also significantly associated with the ZBI. To find the independent association of the ZBI, multiple regression analysis was performed. The results showed that DASC-21 (P < 0.001) and NPI (P < 0.001) had significant correlation. For each item of the DASC-21, Memory (P = 0.014) and Solving issues/Common sense (P < 0.001) were also shown to have significant correlation.

CONCLUSIONS

Both BPSD, cognition and IADL have affected caregiver burden. The DASC-21 is useful for determining the causes of caregiver burden of dementia patients.

Caregiver burden in older adults with bipolar disorder: relationship to functionality and neuropsychiatric symptoms

BACKGROUND

There are few studies addressing caregivers of bipolar disorder (BD) patients, especially patients who are older adults with an increased need for care, often given by a relative. The aim of this study was to describe which factors increase caregiver burden among caregivers of elderly BD outpatients.

METHODS

Patients were older than 60 years and met the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, criteria for BD. They were evaluated for current mood, cognitive and other neuropsychiatric symptoms, functionality, medical comorbidities, quality of life, years since BD diagnosis, and number of psychiatric admissions. The caregiver who spent the greatest time with each patient was evaluated with the Zarit Caregiver Burden Interview. The caregivers' global health, mood symptoms, quality of life, and tasks performed for the patient were also assessed.

RESULTS

Thirty-six BD patients and their caregivers were assessed. The Zarit Caregiver Burden Interview was positively correlated with patients' neuropsychiatric symptoms (r = 0.508, P = 0.002) and functional impairment (r = 0.466, P = 0.004). The Zarit Caregiver Burden Interview was also correlated with caregivers' own depression (r = 0.576, P < 0.001), anxiety (r = 0.360, P = 0.031), quality of life (r = -0.406, P = 0.014), medical comorbidities (r = 0.387, P = 0.020), and number of tasks that they completed for the patient (r = 0.480, P = 0.003).

CONCLUSIONS

In this group of elderly BD patients, caregiver burden was more associated with symptoms frequently seen in others diseases as in dementia than with depressive, manic, or anxiety symptoms, which are often used as treatment outcomes measures goals in BD. Potential treatable and modifiable factors associated with caregiver burden could be caregivers' depression, anxiety, and medical comorbidities, as well as support for caregivers in terms of services and social relationships.

Neuropsychiatric symptoms of the elderly with Alzheimer's disease and the family caregivers' distress

OBJECTIVE

to analyze the relationship between the distress of the family caregiver and the presence of neuropsychiatric symptoms in elderly patients with Alzheimer's disease or mixed dementia.

METHOD

a descriptive, cross-sectional study conducted in the Geriatric and Dementias Clinic of a general tertiary hospital, with 96 elderly people with Alzheimer's disease or mixed dementia and their family caregivers. Questionnaires to characterize the elderly and caregivers, and the Neuropsychiatric Inventory were used. Descriptive statistics and Pearson correlation test were performed.

RESULTS

68.7% of the elderly were women, average age 80.8 years, 56.2% had Alzheimer's disease and 43.7%, mixed dementia. Among caregivers, 90.6% were women, average age 56, 70.8% took care of parents and 64.6% lived with the elderly. There was a strong (r = 0.82) and significant (p <0.01) correlation between the total score on the Neuropsychiatric Inventory and the total score on the Neuropsychiatric Inventory-Distress and strong (r = 0.80) and significant (p <0 01) correlation between the total score on the Neuropsychiatric Inventory Distress and the number of neuropsychiatric symptoms, i.e., the higher the number, frequency and severity of these symptoms in the elderly, the more intense is the caregiver distress.

CONCLUSION

the presence of neuropsychiatric symptoms in the elderly was related to increased distress in caregivers.

Measuring the impact of informal elderly caregiving: a systematic review of tools

PURPOSE

To classify and identify the main characteristics of the tools used in practice to assess the impact of elderly caregiving on the informal carers' life.

METHODS

A systematic review of literature was performed searching in Embase, MEDLINE, PsycINFO, CINAHL, IBECS, LILACS, SiiS, SSCI and Cochrane Library from 2009 to 2013 in English, Spanish, Portuguese and French, and in reference lists of included papers.

RESULTS

The review included 79 studies, among them several in languages other than English. Their inclusion increased the variety of identified tools to measure this impact (n = 93) and allowed a wider analysis of their geographical use. While confirming their overlapping nature, instruments were classified according to the degree of integration of dimensions they evaluated and their specificity to the caregiving process: caregiver burden (n = 20), quality of life and well-being (n = 11), management and coping (n = 21), emotional and mental health (n = 29), psychosocial impact (n = 10), physical health and healthy habits (n = 2), and other measures. A high use in practice of tools not validated yet and not caregiver-specific was identified.

CONCLUSIONS

The great variety and characteristics of instruments identified in this review confirm the complexity and multidimensionality of the effects of elderly caregiving on the informal carer's life and explain the difficulties to assess these effects in practice. According to the classification provided, caregiver burden and emotional and mental health are the most evaluated dimensions. However, further work is required to develop integrated and caregiving focused procedures that can appraise this complexity across different countries and cultures.

Correlation between neuropsychiatric symptoms and caregiver burden in a population-based sample from São Paulo, Brazil: a preliminary report

Neuropsychiatric symptoms and caregiver burden are highly prevalent in older adults with Alzheimer's disease (AD).OBJECTIVE: To evaluate the correlation between neuropsychiatric symptoms and caregiver burden in a community-based sample from São Paulo, Brazil.

METHODS

A total of 1,563 randomly-selected subjects were assessed by the Mini-Mental State Examination, Fuld Object Memory Evaluation, Informant Questionnaire on Cognitive Decline in the Elderly and Bayer - Activities of Daily Living Scale. Subjects considered screen-positives were submitted to a dementia workup and diagnosis was determined according to ICD-10 criteria. The neuropsychiatric Inventory was applied to caregivers to evaluate neuropsychiatric symptoms and the Zarit Burden Interview was also applied to assess caregivers' burden.

RESULTS

Sixty-one AD patients, 25 Cognitively Impaired Non Demented (CIND) and 79 healthy elderly subjects were evaluated. Zarit mean scores for controls, CIND and AD were 2.32, 3.92 and 20.11, respectively. There was strong positive correlation between total NPI and Zarit scores.

CONCLUSION

In conclusion, neuropsychiatric symptoms showed a significant association with higher rates of caregiver stress.

Sobrecarga e desconforto emocional em cuidadores de idosos

A finalidade deste estudo foi descrever a sobrecarga e o desconforto emocional dos cuidadores de idosos. Estudo epidemiológico e transversal conduzido em 2009 com 124 cuidadores residentes na comunidade de Ribeirão Preto-SP, por meio dos instrumentos: Escala de Sobrecarga de Zarit e Self-Reporting Questionaire (SRQ-20) para o cuidador. A análise dos dados foi realizada no aplicativo SPSS, 15.0, de forma descritiva, univariada (tabelas de frequência) e bivariada (tabelas de contingência para variáveis qualitativas). Os cuidadores, 85,6% do sexo feminino, média de 56,5 anos, utilizaram, em média, 12,4 horas diárias para o cuidar e 57,6% dos cuidadores apresentaram de leve a moderada sobrecarga. Dependência funcional do idoso, sexo do cuidador e tempo em horas para o cuidado, foram preditores da sobrecarga (p<0,05). Encontrou-se, também, que a sobrecarga é fator de risco para desconforto emocional (p<0,05). Cabe aos enfermeiros utilizarem protocolos de avaliação, com base nos fatores de risco, para prevenir a sobrecarga.

Perfil de cuidadores de idosos com doença de Alzheimer associado à resiliência

Estudo exploratório-descritivo que objetivou descrever variáveis sociodemográficas e de saúde dos cuidadores de idosos com Alzheimer, associando os cuidados realizados à resiliência. Participaram do estudo 101 cuidadores, maiores de 18 anos, que acompanhavam os idosos em unidade básica e em hospital público, no ano 2009. Foram aplicados questionários para perfil, Inventário de Depressão de Beck e Escala de Resiliência. Realizada análise estatística dos dados. A maioria dos cuidadores eram mulheres, sem depressão, recebia ajuda de outras pessoas para cuidar e possuía alto grau de resiliência. Houve associação significativa da resiliência com as variáveis: grau de parentesco, tratamento médico, uso de medicamentos, cansaço, esgotamento, desânimo e saúde mental do cuidador. Saúde física foi associada, significativamente, à experiência no cuidado, sendo que 82 idosos tinham prejuízos cognitivos graves. O idoso no contexto familiar pode ser beneficiado quando o cuidador é mais resiliente.

Assessment of caregiver burden with elderly having cognitive deficit

To characterize the elderly with cognitive déficit, and family caregivers who live in the urban communit,y and to identify the caregiver burden. METHODS: An observational, cross-sectional study, conducted between January and July 2009. Seventy elderly (aged 65 and older) were assessed for cognitive deficit using the Mini Mental State Examination (MMSE); their 70 caregivers were evaluated by the Zarit Burden Scale (ZBS) and the Self Reporting Questionnaire (SRQ). The data were entered and validated by double entry in the MS Excel Program, and were analyzed using SPSS software, version 15.0. RESULTS: Of the caregivers, 47.1% were children. We obtained a mean for the ZBS of 30.3 (± 17.3) and 6.2 (± 3.2) for the SRQ, p <0.05, correlating lower scores of the MMSE with high scores on ZBS and SRQ. CONCLUSIONS: Cognitive deficit of the elderly was a predictive factor for burden and emotional distress of caregivers. Knowing the reduction of cognitive capacity related to caregiver burden is essential for preserving caregiver health.

Neuropsychiatric symptoms as the main determinant of caregiver burden in Alzheimer's disease

Caregiver burden is common in Alzheimer’s disease (AD), decreasing the quality of life among caregivers and patients. Projections of aging and aging-related diseases such as AD in developing countries justify additional data about this issue because people living in these countries have shown similarly high levels of caregiver strain as in the developed world.

Attenuation of neuropsychiatric symptoms and caregiver burden in Alzheimer's disease by motor intervention: a controlled trial

OBJECTIVE

To analyze the effects of motor intervention on the neuropsychiatric symptoms of Alzheimer's disease and on the caregivers' burden.

DESIGN

This is a controlled trial evaluating the effects of a motor intervention program on the neuropsychiatric symptoms.

SETTING

The intervention was performed on community patients from two university centers specializing in physical exercise for the elderly.

SUBJECTS

Patients with Alzheimer's disease were divided into two groups: sixteen received the motor intervention and sixteen controls (five controls were excluded because of clinical intercurrences).

INTERVENTIONS

Aerobic exercises (flexibility, strength, and agility) and functional balance exercises were conducted over six months for 60 minutes three times per week.

MAIN MEASURES

Psychopathological features of patients were evaluated with the Neuropsychiatric Inventory and Cornell Scale for Depression in Dementia. Caregivers were evaluated using the Neuropsychiatric Inventory-Distress and Burden Interview. A two-way analysis of variance (ANOVA) was applied to observe interactions (pre- vs. post-intervention; participants vs. controls).

RESULTS

Patients from the intervention presented a significant reduction in neuropsychiatric conditions when compared to controls (Neuropsychiatric Inventory: F: 11.12; p = 0.01; Cornell Depression scale: F: 11.97; p = 0.01). The burden and stress of caregivers responsible for patients who participated in the intervention significantly decreased when compared to caregivers responsible for controls (Neuropsychiatric Inventory-Distress: F: 9.37; p = 0.01; Burden Interview: F: 11.28; p = 0.01).

CONCLUSIONS

Aerobic exercise was associated with a reduction in the neuropsychiatric symptoms and contributed to attenuate the caregivers' burden. However, the researchers were not blinded to the patient's intervention status, which constitutes an important limitation of this study.

Sociodemographic profile and level of burden of dementia patients' caregivers who participate in a support group

The Brazilian Alzheimer's Association recommend the dementia patient's caregiver to attend group meetings which aim to give information and enable them to express and share feelings with individuals who are facing similar difficulties.

Objectives

To identify the sociodemographic profile of the individuals who attend the Support Group for Family Members of Individuals with Alzheimer's disease at Hospital de Clínicas de Porto Alegre, and to verify the degree of burden associated to the care given to this kind of patient.

Methods

Forty-eight participants were sub-divided into two groups: 23 non-caregivers and 25 caregivers. All participants answered a sociodemographic questionnaire, and the caregivers also answered the Zarit Burden Interview (ZBI). Student's t test was used for comparison of parametric data, and Chi-square test for categorical data between caregivers and non-caregivers. Spearman's rho correlation analysis was performed for the ZBI and the studied variables.

Results

Participants were predominantly women. Only age differentiated one subgroup from the other. The mean score on the ZBI was 35.1 (14.7), and most of the caregivers presented up to moderate burden.

Conclusions

Women attended the Support Group either as caregiver or non-caregiver. The level of burden among caregivers of high educational attainment was relatively high besides the short time as caregiver (up to a year).
