Healthcare professionals' response to cachexia in advanced cancer: a qualitative study

PURPOSE/OBJECTIVES

To explore healthcare professionals' experience, understanding, and perception of the needs of patients with cachexia in advanced cancer.

RESEARCH APPROACH

A qualitative approach based on symbolic interactionism.

SETTING

A regional cancer center in a large teaching hospital in the United Kingdom.

PARTICIPANTS

34 healthcare professionals who had experience providing care to patients with cachexia in advanced cancer.

METHODOLOGIC APPROACH

Data collection consisted of two phases: focus group and semistructured interviews. Interviews were digitally recorded and transcribed verbatim for analysis. This article reports on findings from the second phase of data collection.

FINDINGS

Analysis revealed that professional approaches to cachexia were influenced by three overarching and interthinking themes: knowledge, culture, and resources. Healthcare professionals commonly recognized the impact of the syndrome; however, for nonpalliative healthcare professionals, a culture of avoidance and an overreliance on the biomedical model of care had considerable influence on the management of cachexia in patients with advanced cancer.

CONCLUSIONS

Cachexia management in patients with advanced cancer can be difficult and is directed by a variable combination of the influence of knowledge, culture of the clinical area, and available resources. Distinct differences exist in the management of cachexia among palliative and nonpalliative care professionals.

INTERPRETATION

This study presented a multiprofessional perspective on the management of cachexia in patients with advanced cancer and revealed that cachexia is a complex and challenging syndrome that needs to be addressed from a holistic model of care.

KNOWLEDGE TRANSLATION

Cachexia management in patients with advanced cancer is complex and challenging and is directed by a combination of variables. An overreliance on the biomedical model of health and illness occurs in the management of cachexia in patients with advanced cancer. Cachexia needs to be addressed from a holistic model of care to reflect the multidimensional needs of patients and their families.

A literature review of end-stage renal disease and cachexia: understanding experience to inform evidence-based healthcare

INTRODUCTION

Cachexia is a major cause of morbidity and mortality in people who have end-stage renal disease (ESRD). The majority of research into cachexia in ESRD has focused on the biological aspects of the syndrome and potential treatment modalities. While this research is necessary, it predominately focuses on the physical impact of cachexia in ESRD. The multi-dimensional psychosocial ramifications of this syndrome have been highlighted in other end-stage illness trajectories, but have not been systematically explored in persons who have ESRD.

AIM

This paper discusses why this research is necessary, alongside further studies to help define the pathophysiology of this syndrome.

CONCLUSION

The rich insightful data gained from understanding the patients' illness experience will positively contribute to the limited knowledge base available and inform future holistic patient-centred care delivery which recognises and responds to not only the biological but also the psychosocial impact of cachexia.

Cancer cachexia care: the contribution of qualitative research to evidence-based practice

BACKGROUND

Despite its prevalence and prognostic impact, primary cachexia is not well understood. Its potential to cause considerable psychological stress indicates the need for qualitative research to help understand the perspectives of those affected.

OBJECTIVE

The aims of this study were to describe the perspectives of patients with primary cachexia, of their relatives, and of the healthcare professionals involved in their care and to demonstrate how this evidence can be applied in practice at 4 different levels of application ranging from empathy to coaching.

METHODS

A review of the qualitative literature and empirical qualitative investigation was used to understand the experiences of patients and relatives and the perspectives of professionals.

RESULTS

The main worries expressed by patients and relatives concerned appetite loss, changing appearance, prognosis, and social interaction. We also describe their coping responses and their views of professionals' responses. The main concerns of professionals related to poor communication, lack of clinical guidance, and lack of professional education.

CONCLUSIONS

Understanding patients', families', and professionals' perspectives, and mapping that understanding onto what we know about the trajectory and prognosis of the condition, provides the evidence base for good practice. Qualitative research has a central role to play in providing the knowledge base for the nursing care of patients with cachexia.

IMPLICATIONS FOR PRACTICE

The evidence provided can improve nurses' insight and assist them in assessment of status, the provision of guidance, and coaching. There is a need for the development of a holistic, information-based integrated care pathway for those with cancer cachexia and their families.

Outcomes of a nurse-delivered psychosocial intervention for weight- and eating-related distress in family carers of patients with advanced cancer

BACKGROUND

International expert consensus is that psychosocial intervention is likely to help advanced cancer patients and their family carers affected by weight loss and poor appetite.

PURPOSE

To investigate the potential for a psychosocial intervention, the Macmillan Approach to Weight and Eating (MAWE), to mitigate weight- and eating-related distress in carers of patients with advanced cancer.

METHOD

A controlled before and after study was conducted with carers of advanced cancer patients living in the community in the South of England in 2006-7. It used mixed methods to compare carers exposed to MAWE (n=12) with a control group (n=14).

RESULTS

Weight- and eating-related distress improved in carers exposed to MAWE. Qualitative analysis found that MAWE may help carers by providing information, reassurance, and support for self-management.

CONCLUSION

This preliminary study of MAWE suggests that it provides benefits as a supportive intervention. Further testing is warranted using a more robust experimental design.

Non-steroidal anti-inflammatory drugs for the treatment of cancer cachexia: a systematic review

BACKGROUND

Cancer cachexia is a devastating syndrome of advanced malignancy which negatively impacts on patients' morbidity, mortality and quality of life. Chronic inflammation is a key characteristic of cancer cachexia. Therefore, non-steroidal anti-inflammatory drugs (NSAIDs) may be able to break the cycle of cachexia.

AIM

To systematically review the literature on the use of NSAIDs for the treatment of cachexia in advanced cancer patients.

DESIGN

All titles retrieved through searching were downloaded to a reference management database, duplicates were removed and the remaining citations were checked for eligibility. Full copies of all eligible articles were obtained and reviewed.

DATA SOURCES

Electronic searches (from inception up to 09/2011) included CINAHL, MEDLINE, EMBASE, and Web of Science. Reference lists from reviewed articles, trial registers and abstracts from relevant conferences were searched. Eligibility criteria were (a) Randomised Controlled Trial; (b) participants were adults with cancer with weight loss or a clinical diagnosis of cachexia; (c) administration of oral NSAIDs.

RESULTS

Four studies were included. These studies provided some evidence of positive therapeutic effect on quality of life, performance status, inflammatory markers, weight gain and survival, but there was insufficient evidence demonstrated for their widespread use in practice.

CONCLUSIONS

Insufficient studies have been performed to allow a conclusion to be formed with regard to the effectiveness of NSAIDs in the treatment of cachexia in advanced cancer. Major challenges in this patient cohort include the lack of uniformity of inclusion criteria across studies and the frailty of the patients recruited.

Refractory cachexia and truth-telling about terminal prognosis: a qualitative study

The purpose of this paper is to examine the consequences that medical practitioners' decisions about whether or not to be candid about terminal prognosis have for those suffering from refractory cachexia and their families. It presents the findings of a qualitative study that used focus groups and semi-structured interviews of a volunteer sample of doctors, nurses and dieticians in a cancer centre of a large teaching hospital in Northern Ireland. Respondents reported that some physicians tended to avoid discussing terminal prognosis in a direct manner with their patients. Nurses and dieticians tended to be reluctant to engage in conversations about weight loss with patients with cachexia. One of the reasons they reported for their lack of acknowledgement of weight loss concerned the close association between refractory cachexia and terminal prognosis. Because they viewed the telling of bad news as an exclusive prerogative of medical practitioners, they did not feel in a position to discuss cachexia because they were concerned that this had the potential to raise end-of-life issues that lay outside the boundaries of their professional role. This meant patients and their families were provided with little information about how to cope with the distressing consequences of cachexia.
