The Impact of Frailty on Health Related Quality of Life in Heart Failure

Background/Aims: Most heart failure (HF) hospital discharges involve people \u3e 65 years, many frail. The purpose of this study was to determine if frailty explains variability in health related quality of life (HRQOL) in older adults with HF over and above known correlates. Methods: A frailty index score was developed by weighting age, number of comorbid conditions, and symptom severity. A multivariate hierarchical regression analysis of known predictors of HRQOLgender, income, ethnicity, health perception, NYHA class — were entered first and then the frailty index was entered and regressed on HRQOL in 2 unique samples. Results: When known predictors were tested on a sample they explained 11% (p 0.14) of the variance in HRQOL; when the frailty index score was added 24% (p 0.001) was explained. When the index was validated in a second sample, known predictors explained 15% (p 0.04) of the variance; with the frailty index score 40% (p 0.000) was explained. Conclusion: Frailty explains significant amounts of variance in HRQOL in HF. Treating comorbid conditions and controlling symptoms may improve HRQOL in HF patients. These findings support the need for further research into the impact of frailty on HRQOL in HF patients

Self-Care for the Prevention and Management of Cardiovascular Disease and Stroke: A Scientific Statement for Healthcare Professionals from the American Heart Association

Self‐care is defined as a naturalistic decision‐making process addressing both the prevention and management of chronic illness, with core elements of self‐care maintenance, self‐care monitoring, and self‐care management. In this scientific statement, we describe the importance of self‐care in the American Heart Association mission and vision of building healthier lives, free of cardiovascular diseases and stroke. The evidence supporting specific self‐care behaviors such as diet and exercise, barriers to self‐care, and the effectiveness of self‐care in improving outcomes is reviewed, as is the evidence supporting various individual, family‐based, and community‐based approaches to improving self‐care. Although there are many nuances to the relationships between self‐care and outcomes, there is strong evidence that self‐care is effective in achieving the goals of the treatment plan and cannot be ignored. As such, greater emphasis should be placed on self‐care in evidence‐based guidelines

The Conceptualization and Measurement of Comorbidity: A Review of the Interprofessional Discourse

Chronic medical conditions often occur in combination. Understanding underlying mechanisms causing diseases and their interactions may make it possible to address multiple complex conditions with single or consolidated treatment approaches and improve patients’ health outcomes while reducing costs. Objectives. We present a synthesis of the current interprofessional discourse on the issues surrounding comorbidities. Methods. A targeted review of the literature was conducted using published editorials, commentaries, and review articles. Results. Errors in conceptualization and measurement plague our current understanding of comorbidities. Two potential paths to generating knowledge involve the use of etiological or epidemiological approach. An etiological approach investigates the risk factors and underlying mechanisms potentially leading to consolidation of diagnosis and treatments. Because of the rudimentary stage of knowledge development in this area, this approach will require time and significant research investments. In contrast, the epidemiological approach relies on statistical identification of disease entities that cooccur beyond random chance; this approach carries an accompanying risk of diagnostic and treatment proliferation. Discussion. The concept of comorbidity, its nature, and measurement is in need of meaningful debate by the scientific and clinical communities. Recommendations in the domains of conceptualization, research, and measurement are discussed

The Geriatric Cancer Experience in End of Life: Model Adaptation and Testing

The National Institutes of Health recommends the development of conceptual models to increase rigor and improve evaluation in research. Validated models are essential to guide conceptualizations of phenomena, selection of variables and development of testable hypotheses. Structural equation modeling (SEM) is a methodology useful in model testing due to its ability to account for measurement error and test latent variables. The purpose of this study was to test a model of The Geriatric Cancer Experience in End of Life as adapted from Emanuel and Emanuel\u27s framework for a good death using SEM. It was hypothesized that the model was a five-factor structure composed of clinical status, physical, psychological, spiritual and quality of life domains and that quality of life is dependent on the other factors. The sample was comprised of 403 hospice homecare patients. Fifty six percent were male, 97% were white with a mean age of 77.7. Testing of the model used AMOS statistical software. The initial five-factor model was rejected when fit indices showed mis-specification. A three-factor model with quality of life as an outcome variable showed that 67% of the variability in quality of life is explained by the person\u27s symptom experience and spiritual experience. As the number of symptoms and the associated severity and distress increase, the person\u27s quality of life significantly decreases (ß -0.8). As the spiritual experience increases (the expressed need for inspiration, spiritual activities, and religion) the person\u27s quality of life significantly increases (ß 0.2). This is significant to nursing because the model provides a useful guide for understanding the relationships between symptoms, spiritual needs, and quality of life in end of life geriatric cancer patients and suggests variables and hypotheses for research. This study provides evidence for a strong need for symptom assessment and spiritual assessment, development of plans of care inclusive of symptom control and spiritual care, and implementation and evaluation of those plans utilizing quality of life as an indicator for the outcome of care provided by nurses

Spirituality: Concept Analysis and Model Development

The concept of spirituality has gained increasing attention over the last decade, as evidenced by the number of conceptual and empirical articles published. Many recommend that continued theory development is essential to understand spirituality and guide practice. The aim of this article is to review the nursing research on spirituality and conduct a concept analysis using Chinn and Kramer\u27s method of creating conceptual meaning. A definition of spirituality is presented, and a model constructed from a review of the literature and reflection. Spirituality is defined as: that most human of experiences that seeks to transcend self and find meaning and purpose through connection with others, nature, and/or a Supreme Being, which may or may not involve religious structures or traditions
