Impact of Chronic Heart Failure on Elderly Persons' Daily Life: A Validation Study

The Relationship Between Resilience and Health-Related Quality of Life Among Heart Failure Patients in New York Heart Association Functional Classes II and III

BACKGROUND

Heart failure is an intense, unpredictable, and stressful chronic disease caused by the decline in cardiac pumping function. The influence of heart failure affects patients not only in terms of physical capabilities but also in terms of their emotional and social dimensions, with patients in different functional classes experiencing different levels of effect. Although resilience and health-related quality of life have been studied in populations with heart failure, the scholarly understanding of different functional classes is limited.

PURPOSE

This study was designed to investigate the relationship between resilience and health-related quality of life among patients with heart failure in different physical functional classes in Taiwan.

METHODS

A cross-sectional design was applied to study patients with heart failure in northern Taiwan. Two structured questionnaires, including the Resilience Scale for Adults and the 12-item Short Form Health Survey, were used to assess resilience and health-related quality of life. New York Heart Association functional class was used to determine physical function status, and canonical correlation analysis was used to determine the weight of each resilience and quality-of-life domain for the different functional classes.

RESULTS

The 100 participants had an average age of 65.52 years. Slightly over half (56%) were classified as Functional Class II. A group difference in health-related quality of life was observed. Personal strength (rs = .759) and social competence (rs = -.576) were found to influence the resilience and emotional role dimension of quality of life (rs = -.996) in the Functional Class II group. In addition, family cohesion (rs = -.922), dominant resilience, physical function (rs = .467), and bodily pain (rs = .465) were found to influence quality of life in the Functional Class III group.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The efficacy of measures taken to increase resilience to heart failure varied in patients in different functional classes. Functional Class II individuals were better able to manage the disease using their personal strength, whereas Functional Class III individuals relied more heavily on family support and assistance for this effort. Furthermore, participant feelings about quality of life also varied by functional class, with physical function and bodily pain taking on significantly more importance for Functional Class III individuals.

The Assessment of Post-COVID Fatigue and Its Relationship to the Severity and Duration of Acute COVID Illness

Emerging data suggests that COVID-19 is associated with fatigue well beyond the acute illness period. The present analysis aimed to: (1) characterize the prevalence and incidence of high fatigue at baseline and follow-up; (2) examine the impact of COVID-19 diagnosis on fatigue level following acute illness; and (3) examine the impact of acute COVID-19 symptom severity and duration on fatigue at follow-up. Subjects (n = 1417; 81.0% female; 83.3% White; X¯age = 43.6 years) completed the PROMIS-Fatigue during the initial wave of the pandemic at baseline (April-June 2020) and 9-month follow-up (January-March 2021). A generalized linear model (binomial distribution) was used to examine whether COVID-19 positivity, severity, and duration were associated with higher fatigue level at follow-up. Prevalence of high fatigue at baseline was 21.88% and 22.16% at follow-up, with 8.12% new cases at follow-up. Testing positive for COVID-19 was significantly associated with higher fatigue at follow-up. COVID-19 symptom duration and severity were significantly associated with increased fatigue at follow-up. COVID-19 symptom duration and severity during acute illness may precipitate longer-term fatigue, which could have implications for treatment planning and future research. Future studies should further evaluate the relationship between symptom severity, duration, and fatigue.

The relationship between six-minute walked distance and health-related quality of life in patients with chronic heart failure

Objectives. To assess the relationship between the six-minute walk test (6MWT) and health-related quality of life (HRQL) in patients with chronic heart failure. Methods. Forty-six patients (37 men and 9 women) with chronic heart failure, mean age 68 (SD 9), NYHA II-III and EF 29 (9) % were included. They performed 6MWT and assessed HRQL using two tools, a Swedish version of the 36-item Short Form (SF-36) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ). This was performed repeatedly during a study period of one year. Results. Patients with a walking distance lower than median experienced a lower HRQL than the higher performing half of the cohort, in four dimensions of the SF-36 and the summary of physical and mental components, but not in the dimensions of MLHFQ. Conclusion. Patients with heart failure with a short walking distance assessed their quality of life as inferior in half of the dimensions in the SF-36 but not in the dimensions measured with the MLHFQ. Thus, different aspects of the symptomatology are uncovered using the 6MWT and the different HRQL tools.

Nurses’ Beliefs and Barriers of Delivering Cardiopulmonary Rehabilitation for Heart Failure Patients in Saudi Arabia: A Cross-Sectional Study

Background: Patients with heart failure (HF) may benefit greatly from cardiopulmonary rehabilitation (CR), which is provided by a team of healthcare professionals that often includes nurses. There has been no research on how nurses perceive providing CR or the hurdles that may affect referrals. Methods: All registered nurses in Saudi Arabia’s Eastern Province were given access to a cross-sectional online survey consisting of nine multiple-choice questions that address attitudes, beliefs, and barriers to CR for HF patients in Saudi Arabia. Descriptive statistics were used to characterize the respondents. Results: Altogether, 439 registered nurses participated in the online survey, with men making up 194 (44%) and women 245 (56%). The mean and SD of years of clinical experience in caring for patients with HF were 6 ± 5 years. Out of 439 nurses, 107 (24%) strongly agree, and 255 (58%) agree that CR will enhance the physical fitness of patients. However, 94 (21.1%) strongly agree, and 248 (56.4%) agree that CR might alleviate dyspnea in HF patients. The vast majority of the nurses either strongly agree (90 (20.5%)) or agree (240 (55%)), that CR would help reduce palpitations and fatigue in HF patients. Indeed, 87 (19.81%) strongly agree, and 262 (59.68%) agree that CR would help improve HF patients’ ability to perform daily activities, while 51 (11.6%) strongly agree and 223 (51%) agree that CR would help in reducing hospital readmission. It was shown that 360 (82%) of the 439 nurses favored the delivery of CR programs in hospital-supervised programs, while 368 (83.8%) ranked information on HF disease as the most important aspect of the CR program, followed by information about medications at 305 (69.4%). The availability of CR facilities (36%), the cost of therapy (35%), and the absence of an established standardized referring strategy (34%) were identified as the most significant barriers affecting the referral of patients with HF for CR by nurses. Conclusion: Generally, nurses believed CR helped improve desired clinical outcomes in HF patients. Although a hospital-based program with close supervision is optimal for administering CR, few such options exist. Referrals of patients with HF were hampered by the lack of CR facilities, the cost of intervention, and the lack of a systematic approach to referrals.

Fatigue self-management led by occupational therapists and/or physiotherapists for chronic conditions: A systematic review and meta-analysis

OBJECTIVE

The aim of this study was to investigate the effectiveness of occupational therapist-/physiotherapist-guided fatigue self-management for individuals with chronic conditions.

METHODS

Eight databases, including MEDLINE and EMBASE, were searched until September 2019 to identify relevant studies. Randomised controlled trials and quasi-experimental studies of self-management interventions specifically developed or delivered by occupational therapists/physiotherapists to improve fatigue symptoms of individuals with chronic conditions were included. A narrative synthesis and meta-analysis were conducted to determine the effectiveness of fatigue self-management.

RESULTS

Thirty-eight studies were included, and fatigue self-management approaches led by occupational therapists/physiotherapists were divided into six categories based on the intervention focus: exercise, energy conservation, multimodal programmes, activity pacing, cognitive-behavioural therapy, and comprehensive fatigue management. While all exercise programmes reported significant improvement in fatigue, other categories showed both significant improvement and no improvement in fatigue. Meta-analysis yielded a standardised mean difference of the overall 13 studies: 0.42 (95% confidence interval:-0.62 to - 0.21); standardised mean difference of the seven exercise studies was -0.55 (95% confidence interval: -0.78 to -0.31).

DISCUSSION

Physical exercises inspired by the self-management principles may have positive impacts on fatigue symptoms, quality of life, and other functional abilities.

Association between Chronic Disease Self-Management, Health Status, and Quality of Life in Older Taiwanese Adults with Chronic Illnesses

Aging is accompanied by many chronic comorbidities and disabilities, and entails medical expenses, which affects the quality of life among older adults. The purpose of this study was to investigate whether the health status of older adults with chronic diseases mediates chronic disease self-management to predict quality of life. Methods: This research adopted a cross-sectional correlation study design. Convenient sampling was performed in outpatient departments commonly visited by older adults in a medical center in Southern Taiwan. The following measures were collected: (1) Physiological measurement: left handgrip, right handgrip, and lower extremities’ muscle strength. (2) Questionnaires: cognitive function was measured by the Alzheimer’s disease (AD)-8 scale, possible frailty with the Kihon Checklist (KCL), functional status with the Barthel Index (BI) and the Lawton and Brody Instrumental Activities of Daily Living (IADL) scales, and self-management for chronic disease and quality of life with the (WHOQOL)-BREF, Taiwan version. Results: Chronic disease self-management is correlated with health status and is directly related to quality of life. Chronic disease self-management also indirectly affects quality of life through health status (cognitive status and risk of frailty), showing that health status partly mediates the correlation between chronic disease self-management and quality of life. Conclusions: A health status feedback system should be introduced in related chronic disease self-management measures for older adults so that they can be aware of their own health status and so that their quality of life is improved. Custom-made nursing interventions are necessary for the reduction in or delay of disability or risk of frailty in older adults, thereby enhancing their quality of life.

Gender differences? Factors related to quality of life among patients with Heart failure

Heart failure (HF) is a chronic, progressive disease that substantially decreases patients' quality of life. Few studies have compared quality of life and its related factors across genders in patients with HF. To explore gender differences in quality of life and related factors among adult patients with HF. A comparative study was conducted with 245 HF patients recruited from a medical center and a regional teaching hospital in Taiwan from February 2009 to February 2011. Descriptive and inferential statistics were used, including stepwise multiple regressions. The mean quality of life scores of males were significantly higher than those of females (87.78 ± 13.99 vs. 84.49 ± 11.85). The factors significantly related to quality of life for the male HF patients, in descending order of strength of association were depressive symptoms, physical symptoms, and monthly family income-less than USD 1,000; for the females, the significantly related factors were physical symptoms, depressive symptoms, and monthly family income-less than USD 1,000. The amount variance for which quality of life accounted for male and female HF patients was similar (60% vs. 64%). The results could be used for health professionals to provide more appropriate assessments and care according to gender in the future.

Thai version of the Minnesota Living with Heart Failure Questionnaire: psychometric testing using a longitudinal design

Background: The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is the most widely used diseasespecific instrument for heart failure (HF). However, a Thai version of the MLHFQ has not been available yet. Objective: Test the psychometric properties of the Thai version of the MLHFQ in terms of practicality, reliability, validity, and responsiveness, using a longitudinal design. Methods: One hundred eighty HF outpatients (mean age: 65±12 years; 58% male) were interviewed at Phramongkutklao Hospital, Bangkok between December 2008 and August 2009. Practicality was assessed with interview-times. Reliability was evaluated using Cronbach’s α and intraclass correlation coefficients (ICCs). Validity was tested with correlations between the MLHFQ scores and the SF-36 scores, confirmatory factor analysis, and known-groups validity. Responsiveness was observed with effect sizes (ES) and minimal clinically important differences (MCID). Results: The averaged interview-time was approximately five minutes. The Cronbach’s α and ICCs of the MLHFQ were 0.86-0.93 and 0.84-0.88, respectively. The MLHFQ scores were moderately correlated with the Short Form-36 Health Survey (SF-36) scores, and discriminated the patients with different classes by New York Heart Association. The average ES were medium, ranging from 0.2 to 0.5. The MCID ranged from 1.4 to 14.5 for improved patients and from -1.4 to -12.7 for worsened patients. Conclusion: The Thai version of the MLHFQ showed acceptable psychometric properties. It can be used as a disease-specific instrument to measure health-related quality of life of Thai patients with HF.

A mixed methods study of Tai Chi exercise for patients with chronic heart failure aged 70 years and older

Aims and objectives

This study aimed to evaluate Tai Chi group training among patients with chronic heart failure (CHF) aged 70 years and older.

Background

Physical activity is recommended for CHF treatment. Tai Chi is found to be beneficial to different patient groups, although few studies focus on older patients with CHF.

Design

A mixed methods study. Participants were randomly assigned to Tai Chi training twice a week for 16 weeks (N = 25) or control (N = 20). Quantitative data were collected at baseline, at the end of the training period and 6 months after training, assessing self‐rated fatigue and quality of life, natriuretic peptides and physical performance. Individual qualitative interviews were conducted with participants (N = 10) in the Tai Chi training group.

Results

No statistical differences between the Tai Chi training group and the control group in quality of life or natriuretic peptides was found. After 16 weeks, the training group tended to rate more reduced activity and the control group rated more mental fatigue. Participants in the training group rated increased general fatigue at follow‐up compared with baseline. Qualitative interviews showed that Tai Chi training was experienced as a new, feasible and meaningful activity. The importance of the leader and the group was emphasized. Improvements in balance were mentioned and there was no physical discomfort.

Conclusion

Tai Chi was experienced as a feasible and meaningful form of physical exercise for patients with CHF aged over 70 years despite lack of achieved health improvement. Further investigations, using feasibility and meaningfulness as outcome variables seems to be useful.

Psychometric Evaluation of the Patient-Reported Outcomes Measurement Information System Fatigue-Short Form Across Diverse Populations

BACKGROUND

The need for reliable, valid tools to measure patient-reported outcomes (PROs) is critical both for research and for evaluating treatment effects in practice. The Patient-Reported Outcomes Measurement Information System Fatigue-Short Form v1.0-Fatigue 7a (PROMIS F-SF) has had limited psychometric evaluation in various populations.

OBJECTIVES

The aim of the study is to examine psychometric properties of PROMIS F-SF item responses across various populations.

METHODS

Data from five studies with common data elements were used in this secondary analysis. Samples from patients with fibromyalgia, sickle cell disease, cardiometabolic risk, pregnancy, and healthy controls were used. Reliability was estimated using Cronbach's alpha. Dimensionality was evaluated with confirmatory factor analysis. Concurrent validity was evaluated by examining Pearson's correlations between scores from the PROMIS F-SF, the Multidimensional Fatigue Symptom Inventory-Short Form, and the Brief Fatigue Inventory. Discriminant validity was evaluated by examining Pearson's correlations between scores on the PROMIS F-SF and measures of stress and depressive symptoms. Known groups validity was assessed by comparing PROMIS F-SF scores in the clinical samples to healthy controls.

RESULTS

Reliability of PROMIS F-SF scores was adequate across samples, ranging from .72 in the pregnancy sample to .88 in healthy controls. Unidimensionality was supported in each sample. Concurrent validity was strong; across the groups, correlations with scores on the Multidimensional Fatigue Symptom Inventory-Short Form and Brief Fatigue Inventory ranged from .60 to .85. Correlations of the PROMIS F-SF with measures of stress and depressive mood were moderate to strong, ranging from .37 to .64. PROMIS F-SF scores were significantly higher in clinical samples compared to healthy controls.

DISCUSSION

Reliability and validity of the PROMIS F-SF were acceptable. The PROMIS F-SF is a suitable measure of fatigue across the four diverse clinical populations included in the analysis.

Predictors for Health Related Quality of Life in Persons 65 Years or Older with Chronic Heart Failure

BACKGROUND

A main goal in nursing care of persons with chronic heart failure (HF) is to strengthen their health related quality of life (HRQoL). This presupposes knowledge about the relation between heart failure and HRQoL. Existing studies have shown incongruent results about whether HRQoL is affected differently depending on age or sex of elderly persons with chronic HF.

AIM

This study aimed to investigate if age, sex, disease severity, comorbidity and living conditions predict health related quality of life among persons 65 years or older with chronic HF.

METHODS

The study included a sample of 357 persons. HRQoL was measured by the Minnesota Living with Heart Failure Questionnaire and the Short Form-12 Health Survey Questionnaire. Multiple regression analyses were performed to analyse the relation between the predictors and HRQoL.

RESULTS

The main finding was that self-rated disease severity was strongly associated with HRQoL, but also age, sex, diabetes and respiratory diseases was associated with some of the dimensions of HRQoL.

CONCLUSIONS

Interventions aimed at delaying the progress of the disease, assist persons' to cope with the disease and maintain the domains of HRQoL that are still feasible could be important to improve HRQoL in elderly persons with chronic HF.

Health-related quality of life in elderly patients hospitalized with chronic heart failure

Background

Chronic heart failure is a very common condition in the elderly, characterized not only by high mortality rates, but also by a strong impact on health-related quality of life (HRQOL). Previous studies of HRQOL in elderly heart failure subjects have included mostly outpatients, and little is known about determinants of HRQOL in hospitalized elderly population, especially in Serbia. In this study, we tried to identify factors that influence HRQOL in elderly patients hospitalized with chronic heart failure in Serbia.

Methods

The study population consisted of 136 patients aged 65 years or older hospitalized for chronic heart failure. HRQOL was assessed using the Minnesota Living with Heart Failure questionnaire. Predictors of HRQOL were identified by multiple linear regression analysis.

Results

Univariate analysis showed that patients with lower income, a longer history of chronic heart failure, and longer length of hospital stay, as well as those receiving aldosterone antagonists and digoxin, taking multiple medications, in a higher NYHA class, and showing signs of depression and cognitive impairment had significantly worse HRQOL. Presence of depressive symptoms (P<0.001), higher NYHA class (P=0.021), lower income (P=0.029), and longer duration of heart failure (P=0.049) were independent predictors of poor HRQOL.

Conclusion

Depressive symptoms, higher NYHA class, lower income, and longer duration of chronic heart failure are independent predictors of poor HRQOL in elderly patients hospitalized with chronic heart failure in Serbia. Further, there is an association between multiple medication usage and poor HRQOL, as well as a negative impact of cognitive impairment on HRQOL. Hence, measures should be implemented to identify such patients, especially those with depressive symptoms, and appropriate interventions undertaken in order to improve their HRQOL.

Evidence on the global measurement model of the Minnesota Living with Heart Failure Questionnaire

PURPOSE

The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is the most widely used health-related quality of life measure in both clinical and research settings. Nevertheless, its measurement model has never been confirmed. This study aims to fill that gap with a large international sample.

METHODS

Data from eight studies (3,847 patients with heart failure) from 21 countries were merged and analysed. Common variables included MLHFQ scores, functional capacity, cardiovascular risk factors and the socio-demographic characteristics of the patient. The measurement model of the MLHFQ was assessed by means of exploratory and confirmatory factor analyses (EFA-CFA). The reliability of MLHFQ scores was evaluated using Cronbach's alpha coefficient and the MLHFQ's ability to differentiate among known groups was assessed through severity levels.

RESULTS

Findings from the EFA and CFA suggest that the MLHFQ total and domain-specific scores fall within a bifactor model. The physical and emotional scores were supported within the sample, as was the original total score. Furthermore, a third factor was revealed regarding social environment. The reliability coefficient reached 0.9 for almost all physical and total scores. All the MLHFQ mean scores showed the ability to differentiate among functional capacity groups, with most of the effect size coefficients reaching 0.8.

CONCLUSIONS

Beyond the suitable degree of reliability and validity displayed by the MLHFQ scores in the different country-specific versions, our results confirmed for the first time the unidimensionality of the most commonly used score in HF patients: the total MLHFQ score. Moreover, the social environment domain identified in this study can now be considered when assessing these patients' HRQL, especially as a relevant outcome with regard to disease management.

Does depression impact cognitive impairment in patients with heart failure?

Prevalence studies have noted the cooccurrence of cognitive decline and depression in persons with heart failure. Cognitive impairment is associated with significant mortality and deteriorated quality of life, likely due to impairments in memory and executive function, which impact a patient's ability to understand and comply with prescribed treatment plans. This is especially true in complex diseases such as heart failure. Evidence from literature supports the possibility of a pathophysiological relationship between cognitive impairment, depression, and heart failure. Yet, very few studies have sought to investigate this relationship. This paper reviews current literature on the association between depression and cognitive impairment in persons with heart failure and explores possible mechanisms explaining this complex triad.

Social support and its association with health-related quality of life among older patients with chronic heart failure

BACKGROUND

Social support is generally known to influence health-related quality of life (HRQoL), but this association is not well explored among older patients with chronic heart failure.

AIMS

(1) To describe social support in older patients with chronic heart failure in relation to gender. (2) To investigate if age, gender, cohabitation, perceived financial situation, and disease severity are associated with social support. (3) To investigate if social support is associated with HRQoL after controlling for age, gender, and disease severity.

METHODS

Data were collected in a sample of 349 patients (≥ 65 years) with chronic heart failure. Patients' HRQoL was measured with the Minnesota Living with Heart Failure Questionnaire and the Short Form-12 Health Survey Questionnaire. The Interview Schedule for Social Interaction measured social support. Data were analysed with descriptive statistics, repeated-measure ANOVA, and multiple linear regression analyses with robust standard errors.

RESULTS

Social support was generally rated high, although being a man, living alone, perceiving a problematic financial situation, and high disease severity (NYHA) were associated with lower levels of social support. Age was not associated with social support. Social support was generally associated with HRQoL, in particular the emotional dimensions.

CONCLUSION

Taking social support into account when caring for older patients with heart failure can be of importance for improving or maintaining HRQoL.

Is there benefit in optimising heart failure treatment in over-80 year-old patients? (HF-80 study): study protocol for a randomized controlled trial

BACKGROUND

An aging population and better management of various heart diseases explain the exponential growth in incidence and prevalence of chronic heart failure, with poor prognosis and heavy health costs. Medical management is codified in international guidelines. The management of heart failure in over-80 year-old patients follows these guidelines, but no clinical trials have been able to confirm benefit. Moreover, registries show down-prescription of heart failure treatments in the elderly and over-80s.

METHODS/DESIGN

We present the design of the HF-80 ("Is there benefit in optimising heart failure treatment in over-80 year-old patients?") study, which is a prospective randomised open-label clinical trial with blinded end-points, designed to evaluate the effect of optimising management by adhering to guidelines in over-80 year-old heart failure patients. Patients over 80 years of age admitted with acute heart failure will be included. The primary endpoint is to assess quality of life at 6 months on the Minnesota questionnaire. The secondary endpoints are to assess the effect of optimised management on quality of life, mortality, readmission for acute heart failure, cardiac fibrosis and economic data at 12 months. 80 patients will be included, divided into 2 groups: group A, with usual heart failure management by general practitioners; and group B, with optimised management based on international guidelines.

DISCUSSION

It is necessary to assess the benefit of guidelines in over-80 year-old heart failure patients because of the fragility of this population and the elevated risk of iatrogenic complications.

Exercise in elderly patients with chronic heart failure in primary care: effects on physical capacity and health-related quality of life

INTRODUCTION

Chronic heart failure (CHF) limits exercise capacity which influences physical fitness and health-related quality of life (HRQoL).

AIM

The aim was to determine the effects on physical capacity and HRQoL of an exercise programme in elderly patients with CHF in primary care.

METHODS

An exercise intervention was conducted as a prospective, longitudinal and controlled clinical study in primary care in elderly patients with CHF. Endurance exercise and resistance training were conducted as group-training at the primary care centre and as home training. Follow-up on physical capacity and HRQoL was done at 3, 6 and 12months.

RESULTS

Exercise significantly improved muscle endurance in the intervention group (n=29, mean age 76.2years) compared to the control group (n=31, mean age 74.4years) at all follow-ups except for shoulder flexion right at 12months (shoulder abduction p=0.006, p=0.048, p=0.029; shoulder flexion right p=0.002, p=0.032, p=0.585; shoulder flexion left p=0.000, p=0.046, p=0.004). Six minute walk test improved in the intervention group at 3months (p=0.013) compared to the control group. HRQoL measured by EQ5D-VAS significantly improved in the intervention group at 3 and 12months (p=0.016 and p=0.034) and SF-36, general health (p=0.048) and physical component scale (p=0.026) significantly improved at 3months compared to the control group.

CONCLUSION

This study shows that exercise conducted in groups in primary care and in the patients' homes could be used in elderly patients with CHF. The combination of endurance exercise and resistance training has positive effects on physical capacity. However, the minor effects in HRQoL need further verification in a study with a larger study population.

[Development and reliability evaluation of an instrument to measure health-related quality of life in independent elderly]

This study presents an instrument, the health-related quality of life (HRQOL) profile for independent elderly, to measure the health-related quality of life of the functionally independent elderly assisted in the outpatient setting, based on the adaptation of four validated scales: Short-Form Health Survey (SF-36), Duke-UNC Health Profile (DUHP), Sickness Impact Profile (SIP), and Nottingham Health Profile (NHP). The study also evaluates the instrument's reliability based on its use by two different observers with a 15-day interval. The instrument includes five dimensions (health perception, symptoms, physical function, psychological function, and social function) and 45 items. Reliability evaluation of the QUASI instrument was based on interviews with 142 elderly outpatients in the city of Rio de Janeiro, Brazil. Prevalence-adjusted kappa statistic was used to assess all 45 items. Correlation was also calculated between overall scores and scores on individual dimensions. In the reliability evaluation, 39 of the 45 items showed prevalence-adjusted kappa greater than 0.60.

Qualidade de vida relacionada à Saúde em Idosos com Insuficiência cardíaca: avaliação com instrumento específico

OBJETIVO: Avaliar a qualidade de vida relacionada à Saúde em idosos com insuficiência cardíaca. MÉTODOS: Estudo transversal realizado em dois hospitais universitários. Foram entrevistados 170 idosos com insuficiência cardíaca em seguimento ambulatorial. Para avaliar a qualidade de vida, foi utilizado o instrumento Minnesota Living With Heart Failure Questionnaire. RESULTADOS: Os resultados do estudo apontaram menor influência da doença sobre a dimensão emocional da qualidade de vida. Entretanto, as questões vinculadas à dimensão física, que avaliam fadiga e dispneia, apresentaram maior impacto na qualidade de vida dos idosos. A consistência interna do instrumento específico de qualidade de vida foi alta, indicando confiabilidade satisfatória (α >0,80). CONCLUSÃO: Este estudo possibilitou a avaliação da qualidade de vida dos idosos com insuficiência cardíaca e mostrou a dimensão física, como o aspecto mais comprometido. É essencial a implementação de estratégias que melhorem a função física desses pacientes.

Health-related quality of life among the elderly with heart failure: a generic measurement

CONTEXT AND OBJECTIVE

Health-related quality-of-life (HRQoL) instruments have been greatly used among patients with heart failure (HF), although few of them are specific for elderly people. Among the generic instruments, the Medical Study 36-item Short-Form Health Survey (SF-36) is widely used. The aim here was to evaluate HRQoL among elderly individuals with HF through this generic instrument.

DESIGN AND SETTING

Cross-sectional study at two university hospitals in São Paulo, Brazil.

METHODS

170 elderly people with HF who were being followed up as outpatients were interviewed. To evaluate HRQoL, SF-36 was used.

RESULTS

The sample was composed of subjects with a mean age of 67.5 (± 6.2) years, with a diagnosis of HF for 65.9 (± 42.4) months, in functional class I (38.8%; 66) or II (42.9%; 73) and with reduced left ventricular ejection fraction (LVEF) (51.2%). The mental and social HRQoL domains did not seem to be compromised, since they presented high scores. Patients with HF typically had impaired physical capacity, which may explain the lower scores in the physical domain. Cronbach's alpha coefficients were greater than 0.77 for all dimensions, except for general health status.

CONCLUSION

The HRQoL measurements using SF-36 presented a high level of reliability when applied to Brazilian elderly individuals with HF. This population presented lower scores for the functional capacity and physical dimensions. This provides support for intervention studies aiming towards optimization of HRQoL in this group.

Propriedades psicométricas da Dutch Fatigue Scale e Dutch Exertion Fatigue Scale: versão brasileira

Fadiga é uma resposta humana em diversas situações agudas e crônicas e também na população geral. Este artigo relata estudo realizado para estimar confiabilidade e validade da Dutch Fatigue Scale (DUFS) e da Dutch Exertion Fatigue Scale (DEFS) adaptadas para o Brasil. Trezentos pacientes ambulatoriais com insuficiência cardíaca e 64 voluntários responderam a DUFS e a DEFS vertidas para o português. Análise fatorial sobre o conjunto de itens das duas escalas produziu solução com um fator para cada escala (variância explicada = 53,9%) e boas estimativas de confiabilidade pelo alfa de Chronbach (DUFS=0,85 e DEFS=0,92) foram obtidas. Na amostra de pacientes, os escores nas escalas foram positivamente associados com a classe funcional da insuficiência cardíaca (DUFS e DEFS p=0,000), com os escores de depressão (DUFS r s=0,63; p=0,00 e DEFS r s=0,55; p=0,00) e com distúrbio de sono (DUFS e DEFS p=0,000). As versões brasileiras mostraram propriedades semelhantes as das escalas originais.

Characteristics of fatigue in heart failure patients: a literature review

This is a literature review report to describe characteristics (frequency, intensity and correlates) of fatigue in cases of heart failure. MedLine and LILACS were the examined databases. Out of 89 articles identified, 27 were selected for data extraction. Fatigue frequency ranged from 69% to 88% and fatigue intensities are incomparable due to differences in measurement scales. Quality of life, illness progression, physical activity, social and demographic variables, comorbidity, treatment and who assessed the fatigue were variables studied in relation to fatigue. The diversity of fatigue assessment methods causes difficulties to integrate results on fatigue frequency, characteristics and related factors. No study was found on fatigue characteristics in samples of Brazilian heart failure patients.

The Experience of Fatigue among Elderly Women with Chronic Heart Failure

Background: Fatigue is a common and distressing symptom in chronic heart failure (CHF). Most of the current methods for evaluating patients' symptoms fail to consider the meaning or importance that these symptoms have for the patient.

Aim: To illuminate the lived experience of fatigue among elderly women with CHF.

Method: Narrative interviews were conducted with 10 women with CHF, aged 73–89 years. Interviews were analysed with qualitative content analysis.

Results: The findings are presented in two themes and five subthemes. The first theme, ‘living with the loss of physical energy’, was based on three subthemes describing the experience of fatigue: ‘experiencing a substantial presence of feebleness and unfamiliar bodily sensations’, ‘experiencing unpredictable variations in physical ability’, and ‘needing help from others in daily life’. The second theme, ‘striving for independence while being aware of deteriorating health’, describes how the women managed their life situation; it was based on two subthemes: ‘acknowledging one's remaining abilities’, and ‘being forced to adjust and struggle for independence’.

Conclusions: Fatigue was experienced as loss of physical energy, leading to discrepancies between intention and capacity. The will to reduce dependency on others involved a daily struggle against fatigue.

Feeling hindered by health problems and functional capacity at 60 years and above

It is common to use activities of daily living (ADL) rating scales to identify the impact of health problems such as diseases, impaired eyesight or hearing on daily life. However, for various reasons people with health problems might feel hindered in daily life before limitations in ability to perform ADL have occurred. In addition, there is sparse knowledge of what makes people feel hindered by health problems in relation to their ADL capacity. The aim was to investigate feeling hindered by health problems among 1297 people aged 60-89 living at home in relation to ADL capacity, health problems, life satisfaction, self-esteem, and social and financial resources, using a self-reported questionnaire, including questions from Older Americans' Resources and Services schedule (OARS), Rosenberg's self-esteem and Life Satisfaction Index Z (LSIZ). People feeling greatly hindered by health problems rarely had anyone who could help when they needed support, had lower life satisfaction and self-esteem than those not feeling hindered. Feeling hindered by health problems appeared to take on a different meaning depending on ADL capacity, knowledge that seems essential to include when accomplishing health promotion and rehabilitation interventions, especially at the early stages of reduced ADL capacity.
