Fatigue: a concept analysis

Fatigue is probably the most common symptom of illness affecting sufferers of both acute and chronic conditions. However, confusion surrounds the definition and use of the term fatigue. As with many other nursing concepts, it is a word that is commonly used in colloquial language. This concept analysis aims to identify the attributes that are essential to the concept of fatigue, and to distinguish between its colloquial and its nursing usage by following the strategy suggested by Walker and Avant (1995, Strategies for Theory Construction in Nursing, Appleton Lange, London). A review of the literature identifies nursing uses of the term fatigue which reflect and conflict with colloquial uses. Defining attributes, demonstration cases, antecedents, consequences and empirical referents are identified before a definition of fatigue is developed and proposed for nursing. This clarification of the phenomenon has particular relevance for clinical nursing, future research and the development of fatigue theories.

A Systematic Review and Meta-Analysis of the Pharmacological Treatment of Cancer-Related Fatigue

BACKGROUND Cancer-related fatigue is an important clinical problem. It is common, distressing, and often difficult to treat. There is a role for drug treatment of cancer-related fatigue, but no consensus has been reached on which drugs are useful. This systematic review and meta-analysis aims to review the available evidence and make recommendations for practice and research. METHODS We searched the Cochrane register of controlled trials (through the second quarter 2007), Medline (January 1, 1966, through August 1, 2007), and EMBASE (January 1, 1980, through August 1, 2007) by use of a predetermined list of search terms. Cochrane Collaboration meta-analysis review methodology was used for this study. The change in fatigue score on the instrument used in each study and other outcomes of interest (adverse events and withdrawal rates) were compared between treatment and control arms by use of the standardized mean difference (SMD) with 95% confidence intervals (CIs). All statistical tests were two-sided. RESULTS We identified 27 eligible trials of drug treatments for cancer-related fatigue (with a total of 6746 participants). The overall effect size for all drug classes was small. A meta-analysis of two studies (n = 264 patients) indicated that methylphenidate (a psychostimulant) was superior to placebo (standardized mean difference [SMD] in change in fatigue score = -0.30, 95% confidence interval [CI] = -0.54 to -0.05; P = .02) for treating cancer-related fatigue. A meta-analysis of 10 studies (n = 2226 patients) evaluating erythropoietin in anemic cancer patients who were undergoing chemotherapy indicated that erythropoietin was superior to placebo (SMD = -0.30, 95% CI = -0.46 to -0.29; P = .008). Among anemic patients (four studies with n = 964 patients), improvement in fatigue was associated with darbepoetin treatment compared with placebo treatment (SMD = -0.13, 95% CI = -0.27 to 0.00; P = .05). Progestational steroids and paroxetine were no better than placebo in the treatment of cancer-related fatigue. CONCLUSIONS There is some evidence that treatment of cancer-related fatigue with methylphenidate appears to be effective. More robust evidence indicates that treatment with hematopoietic agents appears to relieve cancer-related fatigue caused by chemotherapy-induced anemia. Further confirmatory trials are required for both observations.

Communication training for health professionals who care for patients with cancer: a systematic review of effectiveness

BackgroundEffective communication is increasingly recognised as a core clinical skill. However, there is evidence that health and social care professionals still lack basic communication skills.PurposeTo assess the effectiveness of different communication skills training courses for health professionals in cancer care.MethodsWe searched six computerised databases and augmented this with a follow-up of references and grey (unpublished) literature. We included all studies evaluating communication training and assessed methodological quality according to the standard grading system of the Clinical Outcomes Group. Data on author, year, setting, objectives, study design and results were extracted and compared in tabular format.ResultsA total of 47 studies potentially assessing communication training in the area of cancer care were identified. Sixteen papers were included describing 13 interventions. Four were randomised controlled trials (RCTs) (grade I), with samples ranging from 72 to 233 subjects. The others were all grade III. Eleven interventions trained health professionals, two trained medical students. The outcomes measured included communication skills as assessed on audio or video, professionals’ self-report and patient assessment. All the interventions demonstrated modest improvements (effect sizes ranged 0.15–2) and one found deterioration in the outcomes measured.ConclusionCommunication training improves basic communication skills. Positive attitudes and beliefs are needed to maintain skills over time in clinical practice and to effectively handle emotional situations.

Improving generalist end of life care: national consultation with practitioners, commissioners, academics, and service user groups

Objective To identify major concerns of national and local importance in the provision, commissioning, research, and use of generalist end of life care. Design A national consultation and prioritising exercise using a modified form of the nominal group technique. Participants Healthcare practitioners, commissioners, academics, and representatives of user and voluntary groups. Setting Primary and secondary care, specialist palliative care, and academic and voluntary sectors in England and Scotland. Results 74% of those invited (210/285) participated. The stage of life to which “end of life care” referred was not understood in a uniform way. Perceptions ranged from a period of more than a year to the last few days of life. Prominent concerns included difficulties in prognosis and the availability of adequate support for patients with advanced non-malignant disease. Generalists in both primary and secondary care were usually caring for only a few patients approaching the end of life at any one time at a point in time. It was therefore challenging to maintain skills and expertise particularly as educational opportunities were often limited. End of life care took place among many other competing and incentivised activities for general practitioners in the community. More needs to be known about models of end of life care and how these can be integrated in a generalist’s workload. A greater evidence base is needed about the effectiveness and application of current tools such as the gold standards framework and Liverpool care pathway and about models of palliation in patients with diseases other than cancer. Conclusions Definitions of end of life care need clarification and standardisation. A greater evidence base is needed to define models of good practice together with a commitment to provide education and training and adequate resources for service provision. More needs to be known about the context of provision and the influence of competing priorities and incentives.

Fatigue in patients with cancer and chronic obstructive airways disease: a phenomenological enquiry

Fatigue is frequently experienced by patients with chronic illnesses, and especially by patients with cancer and chronic obstructive airways disease. However, there is a paucity of qualitative research into the experiences of fatigued individuals and, consequently, definitions of fatigue have, to date, been based solely on observation and conjecture. The purpose of this study was to capture a detailed description of the fatigue experienced by individuals with cancer and chronic obstructive airways disease. A phenomenological research design was adopted. The findings presented in this paper depict fatigue as a complex phenomenon. The paper describes the physical and mental sensations embodied in fatigue, the impact of fatigue on everyday functioning, the emotional feelings evoked by fatigue and the impact of fatigue on perceived control. These findings have relevance for clinical nursing and future research.

Rethinking the patient: Using Burden of Treatment Theory to understand the changing dynamics of illness

BackgroundIn this article we outline Burden of Treatment Theory, a new model of the relationship between sick people, their social networks, and healthcare services. Health services face the challenge of growing populations with long-term and life-limiting conditions, they have responded to this by delegating to sick people and their networks routine work aimed at managing symptoms, and at retarding – and sometimes preventing – disease progression. This is the new proactive work of patient-hood for which patients are increasingly accountable: founded on ideas about self-care, self-empowerment, and self-actualization, and on new technologies and treatment modalities which can be shifted from the clinic into the community. These place new demands on sick people, which they may experience as burdens of treatment.DiscussionAs the burdens accumulate some patients are overwhelmed, and the consequences are likely to be poor healthcare outcomes for individual patients, increasing strain on caregivers, and rising demand and costs of healthcare services. In the face of these challenges we need to better understand the resources that patients draw upon as they respond to the demands of both burdens of illness and burdens of treatment, and the ways that resources interact with healthcare utilization.SummaryBurden of Treatment Theory is oriented to understanding how capacity for action interacts with the work that stems from healthcare. Burden of Treatment Theory is a structural model that focuses on the work that patients and their networks do. It thus helps us understand variations in healthcare utilization and adherence in different healthcare settings and clinical contexts.

Communication training for health professionals who care for patients with cancer: a systematic review of training methods

BackgroundEffective communication is increasingly recognised as a core clinical skill. Many health and social care professionals, however, do not feel adequately trained in communicating and in handling interpersonal issues that arise in the care of patients with cancer.AimThe aim of this paper was to assess the effectiveness of different training methods used in communication training courses for health professionals.MethodWe searched six computerised databases and augmented this with follow-up of references and grey (unpublished) literature. We included all studies evaluating communication training and assessed methodological quality according to the standard grading system of the Clinical Outcomes Group. Data on author, year, setting, objectives, study design and training methods were extracted and compared in tabular format.ResultsA total of 47 studies potentially assessing communication training were identified. Sixteen papers were included evaluating 13 interventions. Four were randomised controlled trials (RCTs) (grade a); the others were grade III. Eleven interventions trained health professionals; two trained medical students. Interventions for training in communication skills were characterised by the variety of communication approaches used and a diversity of methods. They were applied to health professionals with very different roles, served different purposes and evaluated a variety of outcome measures: behavioural assessments, patient outcomes and professionals’ self-report.ConclusionsThe best results are to be expected from a training programme that is carried out over a longer period of time. Learner-centred programmes using several methods combining a didactic component focusing on theoretical knowledge with practical rehearsal and constructive feedback from peers and skilled facilitators proved to be very effective. Small groups encouraged more intensive participation. Training in communication for both medical or nursing students and senior health professionals is advisable.

Patients’ needs assessment in cancer care: a review of assessment tools

BackgroundThe assessment of patients’ needs for care is a critical step in achieving patient-centred cancer care. Tools can be used to assess needs and inform care planning. This review discusses the importance of systematic assessment of needs in routine care and the contribution tools can make to this process.MethodA rapid appraisal was undertaken to identify currently available tools for patient assessment in cancer care through searches conducted with Medline and CINHAL databases. It focused on tools for the systematic assessment of individual patients’ needs for help, care or support, to be used for clinical purposes—not for research or other purposes. Tools that focused on a single domain of care such as psychosocial needs were excluded, as were studies of patient satisfaction. A wide list of search terms was used, with references stored and managed using bibliographic software.ResultsIn all, 1,803 papers were identified from the initial search, with 91 papers found to be relevant; although 36 tools were identified, only 15 tools were found to fit our criteria. These were appraised for their validity, reliability, responsiveness to change and feasibility, including acceptability to patients. The process of their development and psychometric properties were reasonably well documented, but data on how feasible they were to use in practice was scarce. Each tool met some but not all the widely accepted criteria for validity, reliability, responsiveness and burden. None were found to be complete for all dimensions of needs assessment. Most have not been sufficiently well tested for use in routine care.ConclusionThere is a need to continue to develop and test tools that have the attributes necessary for effective practice and to research their effects on the quality of supportive cancer care.

Psychostimulants for the management of cancer-related fatigue: a systematic review and meta-analysis.

CONTEXT Cancer-related fatigue (CRF) is a common and distressing symptom affecting patients with cancer. There is an increasing number of drug trials examining potential treatments for CRF. Methylphenidate represents one of the most researched drugs in this area, and an up-to-date assessment of the evidence for its use is needed. OBJECTIVES To assess and summarize the increasing evidence for the use of psychostimulants, particularly methylphenidate, in the treatment of CRF. METHODS A systematic review of electronic databases was conducted from inception to the start of October 2009, together with cross-referencing of cited abstracts and hand searching of relevant cancer journals. RESULTS A meta-analysis was conducted on five psychostimulant trials (n=426 participants). The overall standardized mean difference was -0.28 (95% confidence interval [CI] -0.48, -0.09; P=0.005), although several trials failed to find any benefit over placebo. There were no differences in the frequency of adverse events between methylphenidate and placebo: combined odds ratio 1.24 (95% CI 0.42, 3.62). CONCLUSION There is preliminary evidence for the use of psychostimulants to treat CRF. The absolute numbers still remain small, and further confirmation is needed before firm recommendations on their usage and safety can be made in the treatment of CRF.

Hypnosis for nausea and vomiting in cancer chemotherapy: a systematic review of the research evidence

To systematically review the research evidence on the effectiveness of hypnosis for cancer chemotherapy-induced nausea and vomiting (CINV). A compre-hensive search of major biomedical databases including MEDLINE, EMBASE, ClNAHL, PsycINFO and the Cochrane Library was conducted. Specialist complementary and alternative medicine databases were searched and efforts were made to identify unpublished and ongoing research. Citations were included from the databases’ inception to March 2005. Randomized controlled trials (RCTs) were appraised and meta-analysis undertaken. Clinical commentaries were obtained. Six RCTs evaluating the effectiveness of hypnosis in CINV were found. In five of these studies the participants were children. Studies report positive results including statistically significant reductions in anticipatory and CINV. Meta-analysis revealed a large effect size of hypnotic treatment when compared with treatment as usual, and the effect was at least as large as that of cognitive–behavioural therapy. Meta-analysis has demonstrated that hypnosis could be a clinically valuable intervention for anticipatory and CINV in children with cancer. Further research into the effectiveness, acceptance and feasibility of hypnosis in CINV, particularly in adults, is suggested. Future studies should assess suggestibility and provide full details of the hypnotic intervention.
