Fatigue in multiple sclerosis: guidelines for nursing care.

Fatigue is a common chronic symptom of multiple sclerosis (MS) that can have disabling effects on the patient's quality of life. The cause of this fatigue is unknown, and there is no specific treatment for it. This article presents the major problem areas and manifestations associated with fatigue and incorporates suggested guidelines for the rehabilitation nurse to use in helping patients with MS manage this symptom. Major symptom areas include (a) physiological problems, (b) affective/behavioral/cognitive problems, and (c) environmental problems. Comprehensive intervention is addressed and the concept of fatigue as a nursing diagnosis is presented.     

The meaning of fatigue for women with multiple sclerosis

AIM: This paper reports the findings of a study that aimed to elucidate the meaning of fatigue for women with multiple sclerosis (MS). BACKGROUND: Living with chronic illness can involve giving up usual activities. MS is a chronic autoimmune disease of the central nervous system. Fatigue is a common experience among people with MS; however, little is known about the meaning of fatigue experienced by women with this condition. METHOD: Ten women with MS were interviewed about their experience of fatigue. A phenomenological hermeneutic method influenced by Ricoeur was used to interpret the transcribed interviews. FINDINGS: The findings were presented in two major themes with five subthemes; experiencing the body as a barrier and experiencing a different absence. Fatigue seemed to give rise to an experience of being absent and divided into two parts. This also led to a feeling of not being able to participate in the surrounding world. The feeling of being an outsider and lacking the ability as a healthy person is interpreted as a form of suffering. Although the fatigue had a great impact on the women's daily life, the women still hoped for some relief. Fatigue seemed to imply that instead of working as an implement to manage in the world the body has become an enemy of survival. CONCLUSION: This study highlights the importance for nurses of understanding how women with MS experience fatigue, which is a prerequisite for communication based on a shared understanding. This awareness would enhance nurses' opportunities to alleviate suffering. More research is needed to investigate what kinds of interventions can help these women to manage their everyday lives and to maintain a sense of normality despite their fatigue and illness. Such interventions should be subject to empirical evaluation research.     

Measurement of fatigue in chronic obstructive pulmonary disease and in asthma

Despite recognition of a high prevalence of fatigue in individuals with chronic airflow obstruction conditions, including chronic obstructive pulmonary disease and asthma, and its importance from a quality of life perspective, no research was found in which fatigue was measured directly in these populations. This may be due to a seeming lack of appropriate instruments for measuring fatigue in these populations. The purpose of this study, therefore, was to pretest an instrument, the Piper Fatigue Scale, which was developed to measure chronic fatigue in clinical populations. The outpatient sample consisted of 17 persons with chronic obstructive pulmonary disease and 19 with asthma. Findings revealed that the visual analogue scale version of the Piper Fatigue Scale may not be appropriate for measuring fatigue in these populations. Instruments with validity and reliability for fatigue in chronic obstructive pulmonary disease and asthma need to be developed.     

Validation study of the Japanese version of the brief fatigue inventory

Fatigue has been recognized as one of the most distressing symptoms in cancer patients. Concise assessment is essential to managing this symptom. To that end, the Brief Fatigue Inventory (BFI), a 9-item questionnaire, was designed to assess fatigue in cancer patients. The purpose of this study was to examine the validity and reliability of the Japanese version of this scale (BFI-J), when compared with previously validated fatigue instruments. We randomly selected 252 cancer patients and presented them with the BFI-J, along with the Cancer Fatigue Scale; Profile of Mood States fatigue, vigor, and depression subscales; and European Organization for Research and Treatment of Cancer QLQ-C30. Specifically, the reliability and construct, criterion, convergent, and discriminant validity of each instrument were evaluated. Additionally, fatigue severity classification was explored using the BFI-J. The results indicated that the BFI-J is a brief, valid, and feasible measure of fatigue for use with Japanese cancer patients.     

Fatigue in chronic migraine patients

Fatigue is a common symptom frequently reported in many disorders including headaches, but little is known about its nature. The objective was to determine the prevalence of fatigue in chronic migraine (CM) patients, to define its subtypes and its relationship with other conditions comorbid with CM. Sixty-three CM patients were analysed. The Fatigue Severity Scale (FSS), the Chalder fatigue scale and the CDC diagnostic criteria for chronic fatigue syndrome (CFS) were used. Fifty-three (84.1%) patients had FSS scores greater than 27. Forty-two (66.7%) patients met the CDC criteria for CFS. Thirty-two patients (50.8%) met the modified CDC criteria (without headache). Beck depression scores correlated with FSS, mental and physical fatigue scores. Trait anxiety scores also correlated with fatigue scales. Women had higher FSS scores than men, P < 0.05. Physical fatigue was associated with fibromyalgia, P < 0.05. Fatigue as a symptom and CFS as a disorder are both common in CM patients. Therapeutic interventions include a graded aerobic exercise program, cognitive behavioural therapy and antidepressants. Identification of fatigue and its subtypes in headache disorders and recognition of headaches in CFS patients has implications for the pathophysiology, diagnosis and treatment of these disorders.     

Fatigue in chronic disease

Fatigue is an extremely common complaint among patients with chronic disease. However, because of the subjective nature of fatigue, and the lack of effective therapeutics with which to treat fatigue, this symptom is often ignored by clinicians, who instead focus on hard, objective disease end-points. Recently, the symptom of fatigue has received greater attention as part of overall health-related quality of life assessments in patients with chronic disease. Furthermore, new methods are being developed to help quantify fatigue, and are being utilized more frequently in the clinical setting. Moreover, studies in patients and using animal models of disease have provided some insight into changes within the brain which appear to be linked to the genesis of central fatigue. This review focuses on fatigue in chronic disease and outlines possible mechanisms which may give rise to central fatigue in chronic disease. Moreover, methods for measuring fatigue and an approach to the fatigued patient are discussed. Hopefully, a broader understanding of this distressing symptom will lead to the development of specific therapies for treating fatigue in these patients.     

Severity of fatigue is related to functional limitation and health in patients with chronic obstructive pulmonary disease

Fatigue is one of the most prevalent symptoms in patients with chronic obstructive pulmonary disease (COPD). In research as well as in clinical practise, fatigue and its influence on functioning and health has not been in focus. The aim of this study was to compare fatigue, functional limitations owing to fatigue and health between patients with COPD and individuals from the general population to assess the differences between patients experiencing no, moderate and severe fatigue. Patients with COPD (n = 151) and individuals from the general population (n = 95) answered questions about fatigue, the Fatigue Impact Scale and the Medical Outcomes Survey Short Form‐36. The patients with COPD reported a higher frequency, longer daily duration and more severity of fatigue compared with individuals from the general population as well as more functional limitations and worse health. The patients who reported severe fatigue had more functional limitations and worse health compared with patients reporting moderate fatigue. These results indicate that fatigue severity should be screened for during the nursing care process with purpose to reduce the symptom burden.     

Fatigue is a prevalent and severe symptom associated with uncertainty and sense of coherence in patients with chronic heart failure.

INTRODUCTION: Fatigue is a common symptom in patients with chronic heart failure (CHF) and has a major impact on their daily life activities. The purpose of this study was to examine the prevalence and severity of fatigue, conceptualized as a multiple dimensional symptom, and to determine the influence of sense of coherence and uncertainty on the fatigue experience in patients with CHF. METHODS: Ninety-three consecutive patients, hospitalized with a diagnosis of CHF, completed the Multidimensional Fatigue Inventory Scale (MFI-20), Cardiovascular Population Scale (CPS), and Sense of Coherence Scale (SOC) and were classified according to the New York Heart Association (NYHA) functional classification criteria. Associations between selected variables were explored with multiple regression analysis. RESULTS: The patients reported high prevalence and severity in the physical dimensions of fatigue. Uncertainty was associated positively with tiredness and reduced functional status. High age predicted reduced motivation and the ability to concentrate were affected by low SOC. CONCLUSION: Fatigue is a prevalent and distressing experience in patients with CHF, where a variety of factors influence different dimensions of the fatigue experience. Recognising this, symptom management must be directed towards comprehensive assessment and a broad approach in interventions aimed at alleviating fatigue.

What is Fatigue? Pathological and Nonpathological Fatigue

Aid in understanding issues surrounding the construct validity of fatigue including the distinction between pathological versus nonpathological fatigue. Fatigue is a universal symptom reported by individuals in the general population as well as by those suffering from different medical and psychological illnesses, including cancer, multiple sclerosis, chronic fatigue syndrome, depression, and anxiety. Chronic fatigue is a significant problem in many primary care settings, and the debilitating and prolonged nature of fatigue can pose significant economic consequences for society. Researchers have struggled to better assess and understand the etiology and classification of fatigue within different illness groups.     

The Measurement of Fatigue in Chronic Illness: A Systematic Review of Unidimensional and Multidimensional Fatigue Measures

Fatigue is a common symptom associated with a wide range of chronic diseases. A large number of instruments have been developed to measure fatigue. An assessment regarding the reliability, validity, and utility of fatigue measures is time-consuming for the clinician and researcher, and few reviews exist on which to draw such information. The aim of this article is to present a critical review of fatigue measures, the populations in which the scales have been used, and the extent to which the psychometric properties of each instrument have been evaluated to provide clinicians and researchers with information on which to base decisions. Seven databases were searched for all articles that measured fatigue and offered an insight into the psychometric properties of the scales used over the period 1980–2007. Criteria for judging the “ideal” measure were developed to encompass scale usability, clinical/research utility, and the robustness of psychometric properties. Twenty-two fatigue measures met the inclusion criteria and were evaluated. A further 17 measures met some of the criteria, but have not been tested beyond initial development, and are reviewed briefly at the end of the article. The review did not identify any instrument that met all the criteria of an ideal instrument. However, a small number of short instruments demonstrated good psychometric properties (Fatigue Severity Scale [FSS], Fatigue Impact Scale [FIS], and Brief Fatigue Inventory [BFI]), and three comprehensive instruments demonstrated the same (Fatigue Symptom Inventory [FSI], Multidimensional Assessment of Fatigue [MAF], and Multidimensional Fatigue Symptom Inventory [MFSI]). Only four measures (BFI, FSS, FSI, and MAF) demonstrated the ability to detect change over time. The clinician and researcher also should consider the populations in which the scale has been used previously to assess its validity with their own patient group, and assess the content of a scale to ensure that the key qualitative aspects of fatigue of the population of interest are covered.     

Sensitivity, Specificity, and Usefulness of the Dutch Fatigue Scale

Purpose. To test the sensitivity, specificity, and usefulness of the Dutch Fatigue Scale (DUFS), which is based on NANDAs defining characteristics of fatigue.
Methods. A cross-sectional design was used among domiciliary patients (N = 213) with chronic heart failure (n = 138) and with breastfeeding postpartum women (n = 75).
Findings. Calculations of the sensitivity and specificity of the DUFS, comparisons of the average DUFS sumscores between both nonfatigued and fatigued subjects, as well as between patients with chronic heart failure and postpartum women, and correlation coefficients performed with sociodemographic factors (age, gender, education) demonstrate acceptable psychometric properties.
Conclusions. The DUFS is a reliable and valid measurement tool for the assessment of fatigue.
Practice Implications. Accurate recognition of the existence and extent of fatigue must precede interventions. Easy to use, reliable tools for the bedside nurse are invaluable assets to practice.

Fatigue after stroke: relationship to mobility, fitness, ambulatory activity, social support, and falls efficacy.

Fatigue is common and persistent in stroke survivors, yet it is not known how mobility deficits, fitness, or other factors, such as social support, relate to fatigue severity, or whether subjective fatigue contributes to reduced ambulatory activity. The severity of fatigue in a sample of 53 community-dwelling subjects with chronic hemiparetic stroke was examined, and relationships among fatigue and mobility deficit severity, cardiovascular-metabolic fitness, ambulatory activity, social support, and self-efficacy for falls were identified. Measures included the Fatigue Severity Scale, timed 10-meter walks, the Berg Balance Scale, submaximal and peak VO2, total daily step activity derived from microprocessor-linked Step Activity Monitors, the Medical Outcomes Study Social Support Survey, and the Falls Efficacy Scale. Forty-six percent of the sample had severe fatigue. Fatigue showed no relationship to ambulatory activity. Fatigue severity was associated with the Berg Balance Scale (p < .01) and falls efficacy (p < .01), but not with cardiovascular fitness variables. Patients with elevated fatigue severity scores had lower social support (p < .05) and poorer falls efficacy scores (p < .05) than patients reporting less fatigue. Only falls efficacy was predictive of fatigue severity (r2 = 0.216, p < .01). Further studies are needed to evaluate whether rehabilitation strategies that include not only fitness and mobility interventions, but also social/behavioral and self-efficacy components, are associated with reduced fatigue and increased ambulation.     

Perceived Short- and Long-Term Effects of Bereavement Support Group Participation at the Hospice of Petaluma

Fatigue is a symptom that is frequently found in chronic pain patients with low back pain and/or neck pain. At the present time, no specific psychopharmacological treatment for this problem has been identified. Modafinil is a wakefulness-promoting agent that the FDA has approved for the treatment of excessive daytime sleepiness associated with narcolepsy. There have been reports on the use of modafinil for the treatment of fatigue in various neurological syndromes. This literature is reviewed. As such, modafinil treatment was initiated for a patient with severe fatigue associated with chronic low back pain and neck pain. There was dramatic improvement in fatigue and associated function. This case is described. It is the first such case report in the literature. The significance of this finding to the treatment of pain-associated fatigue is discussed.

Fatigue and rheumatoid arthritis.

Fatigue is a common complaint among patients with rheumatoid arthritis (RA) and is regarded as an extra-articular symptom of the disease. Little attention has been paid by health professional teams to the multidimensional nature of RA-related fatigue and its wide-ranging consequences for quality of life. Unlike normal tiredness, fatigue is chronic, typically not related to overexertion and poorly relieved by rest. The prevalence is high and several RA-related components have been reported as predictors of fatigue. RA-related fatigue appeared to be strongly associated with psychosocial factors. Fatigue assessment and management are complex because psychological and physiological factors may be involved. Several instruments that have been used in RA to assess fatigue. They have involved a self-reporting format. Some are brief, quantitative and symptom-focused questionnaires. Others provide a multidimensional assessment. DMARD therapy, especially anti-TNF decreased disease activity and alleviates fatigue. An additional direct effect is hypothetical. The non-pharmacological management includes behavioral therapy or self-management courses and physical exercise. Finally, the importance and relevance of fatigue as an outcome measure is becoming highlighted by research groups and should lead to improved management of fatigue in usual medical practice.
