A qualitative study to explore the experience of fatigue in cancer patients

Fatigue experience in advanced cancer: a phenomenological approach

This study describes the experience of fatigue in patients with advanced cancer. A phenomenological approach was adopted to allow a fuller expression of the phenomenon of fatigue in the sample of six patients. Five major themes were identified. These were physical, psychological, social and spiritual consequences of fatigue, and helpful and unhelpful coping strategies. The themes demonstrate the complexity of fatigue, which had an all-encompassing effect on patients' lives. The themes were interconnected and cannot be viewed independently. For these patients with advanced cancer the meaning of fatigue was intertwined with the process of adjusting to living with a terminal illness and ultimately death. It was impossible for them to separate the two. Coping strategies that would normally be of use to fatigued individuals were shown to have little or no benefit. Sensitive communication about fatigue and its meaning to the patient may assist adjustment and generate hope.

An increasing number of qualitative research papers in oncology and palliative care: does it mean a thorough development of the methodology of research?

BACKGROUND

In the second half of the nineties, a scientific debate about the usefulness of qualitative research in medicine began in the main medical journals as well as the amount of "qualitative" papers published on peer reviewed journals has noticeably increased during these last years. Nevertheless the label of qualitative methodology has been assigned to an heterogeneous collection of studies. Some of them show a complete awareness of the specificity of this kind of research, while others are still largely influenced by the quantitative paradigm prevailing in the medical field. The concern with the rigour and credibility of qualitative methods has lead to the development of a number of checklist for assessing qualitative research. The purposes of this review were to describe the quality of the development of qualitative research in the medical field, focusing on oncology and palliative care, and to discuss the applicability of a descriptive checklist.

METHODS

A review was conducted on Medline and PsycINFO databases. On the basis of their abstract, papers found have been classified considering: publication year, kind of journal, paper type, data gathering method, sample size and declared methodological approach. A sub sample of the previous papers was than selected and their methodological characteristics were evaluated based on a descriptive checklist.

RESULTS

351 abstracts and 26 full papers were analysed. An increase over time in the number of qualitative studies is evident. While most of the papers before 1999 were published on nursing journals (43%), afterwards also medical journals were largely represented. Psychological journals increased from 7% to 12%. The 22% of studies used a sample size lower than 15 and the 15% did not specify the sample size in the abstract. The methodological approach was also often not specified and the percentage increased in the second time period (from 73% to 80%). Grounded theory was the most employed methodological approach while phenomenology shows a decrease. Interview remains the most used data gathering method in both periods, even if it shows a 10% reductions, while focus group and multiple methods application both increase to 12%. The use of the descriptive checklist on the full text of the 26 papers shows that all the items present a larger percentage of satisfaction after 1 January 1999 than it was for the paper published before 1999. There seems to be two different types of quality criteria: specific and unspecific. The first ones mainly refer to qualitative paradigm (such as the relationship with the subject of research or evidence about how subjects perceived the research) and they are often not satisfied. In contrast unspecific criteria (such as the connection to an existing body of knowledge or systematic data gathering) which are mainly shared with the quantitative paradigm are more frequently satisfied.

CONCLUSIONS

In oncology and palliative care the publication of qualitative studies increased during the nineties, reaching its peak in around 2000. The use of descriptive checklists even if it was not easy to apply, allows researchers to get a deeper insight into methodological facets that a global judgement may leave out.

The meaning of quality of life in patients being treated for advanced breast cancer: A qualitative study

The purpose of the present study was to investigate the meaning of advanced breast cancer patients' quality of life (QoL). A semi-structured interview was used, and the phenomenological research method chosen to analyse the data. The findings show that limitations in physical functioning translate into dependency on others, leading to decreased autonomy. Patients tended to ensure their autonomy by participating in easier activities or changing their internal standards. Changes in appearance and decreased condition affected patients' ability to carry out roles and responsibilities, which led to changes in lifestyle and also affected patients' social functioning, often resulting in isolation. The meaning of being able to sustain reciprocal relationships was emphasized. Patients maintained control of to what extent their illness was recognized in social relationships, which was crucial to their feelings of autonomy. Close families were a main source of social support, but also a major source of concern. Meaning of emotional functioning was often expressed in terms of the ability to enjoy life day-by-day and of commitment to treatment. Patients' cognitive functioning was largely intact while their difficulties in cognitive functioning were more characteristic of anxiety. Global QoL was often expressed in terms of a normal life. In addition there were 3 meta themes which emerged from the data: the patients' ability to control the illness experience, personal growth and hope.

Assessment and management of cancer-related fatigue in adults

Fatigue is one of the most prevalent and distressing symptoms of cancer, and is a common side-effect of many of the treatments available for the management of malignant disease. We critically assess the evidence for cancer-related fatigue and its treatment in adults. Little is known about the cause and mechanisms of fatigue, and research into methods of alleviating the condition has focused on treatment for anaemia and behavioural interventions, such as exercise, both of which are effective in reducing fatigue. Although research into the condition has increased considerably in the past decade, important gaps in knowledge remain.

Factors predicting fatigue in breast cancer patients

A prospective study was designed to investigate the factors predicting fatigue in breast cancer patients using the Cancer Fatigue Scale (CFS) in addition to the Hospital Anxiety and Depression Scale (HADS) and a questionnaire containing items on demographic and clinical data, and measures of patients' physical symptoms. The CFS measures total fatigue score ranging from 0 (lowest level) to 60 (highest level) and contains three subscales namely: physical, affective and cognitive fatigue. The questionnaires were administered to a consecutive sample of breast cancer patients attending the Iranian Center for Breast Cancer either for their treatment or follow-up examination. In all, 112 patients were studied. The mean age of the respondents was 45.7 years (SD11.0). Most had stage II breast cancer (67%) and had completed their initial treatment (45%). The mean total fatigue score of the patients was 18.7 (SD 13.5) and overall 49% reported experiencing fatigue to some degree (from quite a bit to very much). Severe anxiety and depression was reported by 16% and 32%, respectively. The regression analysis revealed that fatigue was predicted by depression ( P=0.003), pain ( P=0.005), current tamoxifen use ( P=0.001), undergoing mastectomy ( P=0.03) and anxiety ( P=0.04). The other variables studied did not emerge as significant predictors of fatigue in the regression analysis. The study findings suggest that in comparison to treatment factors, physical and psychological symptoms have a more important role in cancer-related fatigue and that fatigue should be recognized and managed even before commencing breast cancer treatment.

An e-learning caregiving program for prostate cancer patients and family members

e-health interventions have the potential to augment caregiving training for management of chronic disease. Instruction on caregiving functions often key to patients and families' well being is time consuming but not reimbursable in our current health care system. A theoretically defined interactive multimedia program is described which would assess patient and family member's level of preparedness for specific caregiving functions for prostate cancer and provide tailored skill building vignettes on caregiving techniques. Maximizing today's technology, this program is best designed for a hybrid delivery utilizing both web-based resources and a CD-ROM. Feedback from 45 prostate patients and family members from a Midwest cancer center on perceived needs for caregiving training underscores the potential value of a computer supported intervention for some patients and families. Implementation of the software, marketing, and distribution will be guided in part by recent e-health experiences that leave many health professionals appropriately skeptical about the utility of such products.

Assessment and management of fatigue in patients with advanced cancer: developing guidelines

Cancer-related fatigue is one of the most important untreated symptoms of cancer, with a prevalence between 60 and 100%, but there has been a reluctance to prioritize fatigue and develop effective management strategies. The development of standards and guidelines will encourage a more systematic approach and help to stimulate further research. The Mersey Palliative Care Audit Group has developed guidelines for the assessment and management of fatigue. These guidelines were produced following a regional survey, which looked at both the educational needs of nurses, and the impact of fatigue on patients with advanced cancer.

Fatigue in patients with breast cancer receiving adjuvant chemotherapy: a review of the literature

The aim of this literature review was to evaluate the prevalence and course of fatigue in patients with breast cancer undergoing adjuvant chemotherapy and to examine factors relating to fatigue. Fatigue is one of the most common side effects of chemotherapy. High and fluctuating prevalence rates of fatigue have been found not only during but also after adjuvant chemotherapy. The intensity of fatigue seems to be stable throughout the treatment cycles, despite the common perception that more chemotherapy treatments lead to greater fatigue. The first two days after a chemotherapy treatment seem to be the worst period. The influence of factors such as pain, impaired quality of sleep, and depression are be highly consistent across several studies, although it is often not clear whether it is the symptoms that cause the fatigue or vice versa. The outcomes of the studies indicate that several symptoms are interrelated in a network of symptoms. Factors such as changes in weight, menopausal symptoms, coping, social support, and biochemical changes have been mentioned in the literature as potentially contributing to fatigue. Results have been conflicting and need further study.

Self-care for fatigue in patients With HIV

PURPOSE/OBJECTIVES

To identify when fatigue is reported as a problem by people who are HIV positive, what the perception of fatigue is, and which self-care behaviors are used and with what efficacy.

DESIGN

Multisite descriptive study.

SETTING

University-based AIDS clinics, community-based organizations, and homecare agencies located in cities across the United States, in Norway, and through a university Web site.

SAMPLE

Convenience sample of 422 self-identified people who are HIV positive.

MAIN RESEARCH VARIABLES

Symptom description, symptom relief, symptom help, and self-care strategies.

FINDINGS

The sixth most reported symptom in this study, fatigue, was treated with a variety of self-designed strategies. In only three instances was consultation with a healthcare provider (i.e., physician) or an injection (medication not defined) mentioned. The most frequently used interventions were supplements, vitamins, and nutrition followed by sleep and rest; exercise; adjusting activities, approaches, and thoughts; distraction; and complementary and alternative therapies. In addition to self-designed strategies, the media and friends and family were sources of information.

CONCLUSIONS

Fatigue was reported less frequently in this study than in other HIV-, AIDS-, or cancer-related studies. This may be an artifact of the study design. The use of informal networks for assistance, let alone the prevalence of unrelieved fatigue, indicates the need for more attention to this problem among people with AIDS.

IMPLICATIONS FOR NURSING

Careful assessment of the pattern of fatigue and its onset, duration, intervention, and resolution is required if the varied types of fatigue are to be identified and treated successfully.

Making use of qualitative research

Many have discussed the importance of using research in practice. To understand this issue, we examined what authors of qualitative research in oncology said about the uses of their research findings. Analysis ofthe authors' implications sections was conducted with 42 articles published between 1995 and 2001 and indexed in either Medline or CINAHL The two categories from this analysis were implications for future research and communication. The categories and related subcategories are illustrated with selected quotes from some of the articles. Findings confirm the importance of language in health and illness.
