Experiences and views of different key stakeholders on the feasibility of treating cancer-related fatigue

Abstract

Background

Although cancer-related fatigue (CRF) has gained increased attention in the past decade, therapy remains a challenge. Treatment programs are more likely to be effective if the needs and interests of the persons involved are well represented. This can be achieved by stakeholder engagement.

In this paper, different key stakeholders’ experiences and views on the feasibility of treating CRF in the context of supportive care in hospital environments are analyzed.

Method

In a qualitative study with the aim of developing an integrative treatment program for CRF, a total of 22 stakeholders (6 medical oncologists, 5 nurses, 9 patients, 1 patient family member, 1 representative of the Swiss Cancer League) were interviewed either in a face-to-face (n = 12) or focus group setting (n = 2). For data analyses, the method of qualitative content analysis was used.

Results

The stakeholders referred to different contextual factors when talking about the feasibility of treating CRF in the context of supportive care in hospital environments. These included: assessment, reporting and information; treatability; attitude; infrastructure, time-management, costs and affordability; and integrative approach.

Conclusions

Key factors of a feasible treatment approach to CRF are a coherent, cost effective integrative treatment program facilitated by an interdisciplinary team of health care providers. Furthermore, the treatment approach should be patient orientated, adopting an individualized approach. The major challenges of making the integrative treatment program feasible for CRF are resources and interprofessional collaboration.

Peer Review reports

Background

Cancer-related fatigue (CRF) is a prevalent and complex syndrome in cancer patients and cancer survivors regardless of tumor and treatment type, and it is still “underreported, underdiagnosed and undertreated” [1]. A commonly used definition is provided by the National Comprehensive Cancer Network (NCCN): “CRF is a distressing, persistent, subjective sense of physical, emotional and/or cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity and interferes with usual functioning” [1].

There is broad agreement that CRF is difficult to treat with only a single intervention or medication prescribed alone, because of its multiple possible causative factors and the variable patterns of clinical expression in individual patients [2, 3]. Concerning the decision for suitable interventions, it is useful to keep in mind that approximately 51% of cancer patients use complementary medicine (CM) interventions and wish to include them in their further therapies [4, 5].

Therefore, a multimodal CRF treatment program combining pharmacological and non-pharmacological conventional and CM interventions seems highly promising.

How patients experience CRF has been adequately addressed in qualitative health research in the past years [6]. A review of Scott et al. discusses 154 published papers of qualitative studies between 1996 and 2009 that have described the patients’ experiences of CRF and the consequences for those affected by CRF or involved with its care. The studies showed relatively homogenous descriptions of the experience of specific sensations, of the impact of CRF on everyday life and of coping strategies, all of which were based on the levels of cognition, emotions, and physical expression and impact [6]. There was much less emphasis on researching the experiences of other stakeholders involved with CRF, such as caregivers and health professionals. In addition, participatory approaches such as stakeholder engagement were rarely applied to develop and assess treatment programs for CRF.

We developed an integrative treatment program for CRF using stakeholder engagement [7]. The treatment program has three different levels. The first level includes mandatory nonpharmacological interventions: information, motivation and exercise. The second level includes nonpharmacological choice-based interventions, such as mind-body medicine techniques, acupuncture and acupressure. The third level includes pharmacological interventions for severe CRF [7].

The treatment of CRF is first and foremost executed in the field of supportive cancer care [1]. In addition to the question of effective treatment options, there are different important contextual factors related to the feasibility of treating CRF, such as human and financial resources, infrastructure, institutionalization, geographical reachability, symptom management, prevention and views on the effectiveness of specific treatments.

In this paper, we present the results from the stakeholder engagement process asking about the contextual factors related to the feasibility of treating CRF in the experiences and views of the stakeholders, i.e., the people affected by CRF or involved in the treatment of CRF [8, 9] in supportive care in hospital environments. This study was conducted concurrently to the treatment program development study [7].

Methods

In this section, we report the methods applied to answer the research question about the contextual factors related to the feasibility of treating CRF. For details about the approach for developing the integrative treatment program for CRF see Canella et al. 2017 [7].

Stakeholder engagement

Key stakeholders were included to gather data about their experiences and views on the feasibility of treating CRF. They represented the following stakeholder groups: oncologists, radiation oncologists, psycho-oncologists, nurses, nurse experts (holding a Master’s degree or a PhD), representatives of a local Swiss Cancer League, patients, and patient’s family members.

To ensure that we integrated the key stakeholders in the study and that we obtained the relevant experiences with CRF as well as views on CRF [7], we recruited according to the principles of “theoretical sampling” [10]. This meant also to recruit participants from within and from outside the University Hospital Zurich.

From the group of the involved stakeholders, we formed a stakeholder advisory board. We aimed at involving one board member of every stakeholder group. We directly approached persons of whom we knew were very experienced with CRF to join the advisory board. We asked the different clinic directors of our oncology department as well as the nurse director and the representative of a local Swiss Cancer League. In addition, we asked one of our CRF patients to be part of the board. Due to availability issues, the patient family member unfortunately was not able to participate in the advisory board.

The seven board members all had experience with CRF and participated in the whole research process, which included face-to-face interviews, an advisory board meeting about the interpretation of the results and the further development of the integrative treatment program, and several written feedback rounds to reach consensus about the final treatment program.

Qualitative data collection and analysis

The qualitative, participatory study was ethnographic in its nature [11,12,13,14]. Data collection and analysis followed the principles and methods of qualitative content analysis [11]. Qualitative content analysis involves identifying key topics, ideas and their relationships. In addition, formal characteristics of the data and their context are analyzed [11,12,13,14]. We applied qualitative content analysis to focus on the whole spectrum of topics and viewpoints that the stakeholders brought up regarding their experiences with CRF and the feasibility of treating it.

The stakeholders were interviewed either in a semi-structured face-to-face interview or in a focus group setting, both of approximately 90 min in duration [13,14,15]. They could choose to be interviewed at our institute, at their workplace or at their home. The interviewees were asked open questions about their experiences and needs concerning CRF and their opinions of the feasibility of treating CRF.

All interviews were audio recorded, transcribed verbatim and analyzed using qualitative data analysis software MAXQDA, version 11.1.2. We performed investigator triangulation to enhance the reliability of the analysis and the results [16]. In an iterative research process, two researchers analyzed the interview data independently and then discussed and revised their findings until a consensus was reached. The analyses consisted of an audio-club [17] where the researchers listened to the original audio-data in real time and then discussed their perceptions and interpretations with each other. Subsequently, a thematic coding in units of meaning was executed [10, 18] to identify and describe the topics, contextual factors and stakeholder experiences with CRF and its treatment [7].

Results

Participants

Overall, 22 stakeholders were interviewed (see Table 1).

Table 1 Stakeholder characteristics

With the health care providers, we conducted nine face-to-face interviews and one focus group consisting of one nurse and two nurse experts. On average, the health care providers estimated that approximately 57% (range 10%˗100%) of their cancer patients experience CRF.

With the patients, we conducted two face-to-face interviews and one focus group with seven participants.

The patients experienced different types of cancer and were in different stages of treatment after their diagnosis. They all combined standard cancer therapy and CM treatments. Between the patients’ cancer diagnoses and their CRF diagnoses, the average timespan was 10 months. In addition, a numeric rating scale with two questions was used to confirm the CRF diagnosis of the participating patients at the beginning of the project [7, 19]. For further details about the patients cancer characteristics see Canella et al. [7].

The stakeholder advisory board was formed out of the 22 stakeholders. The seven individual board members were interviewed face-to-face as stakeholders independent of the advisory board meetings [7].

Contextual factors related to the feasibility of treating CRF in supportive care in hospital environments

The stakeholders referred to different main topics when talking about the feasibility of treating CRF: assessment, reporting and information; treatability; attitude; infrastructure, time-management, costs and affordability; and integrative approach.

Assessment, reporting and information

The medical doctors, nurses and nurse experts stressed the challenge of assessing CRF and asking their patients about CRF-related symptoms periodically. The health care providers usually did not use a standard diagnostic tool for assessing CRF. “Everyone had more or less an individual approach” (medical oncologist) to ask their patients about symptoms of CRF. It was a challenge for the health care providers to keep track of CRF in their patients because CRF can have multiple causes, can appear in very different stages of cancer and can differ in its clinical expression in the individual patients. The psycho-oncologist added that it is often difficult to differentiate between CRF and other psychological conditions, such as depression or anxiety. A nurse expert linked the topic of assessment and reporting with the observation that medical doctors are often too overburdened with the standard cancer therapy consultation to execute a systematic CRF assessment. She suggested that a systematic implementation of a standard diagnostic tool for CRF might be more feasible if an advanced nursing practitioner could take over that task from the medical doctors.

Some health care providers reported that their patients rarely addressed problems or symptoms of fatigue during the consultation because they were focused on surviving and on the more acute side effects of active cancer therapies.

Patients felt that they were not informed specifically enough about how to treat CRF. They felt like they had to search for treatment options on their own what was challenging while experiencing simultaneously CRF. They wished they could have been monitored for CRF throughout the active cancer therapy but especially after active treatment. The advisory board discussed when would be a good point in time to inform the patients about CRF. They agreed that cancer patients should be informed early after their diagnoses and reflected on the possibility of creating an online information tool for the patients.

Treatability

The health care providers often did not see good results when trying to treat CRF. They also mentioned that there was no specific treatment for CRF in their hospital at the time of the interview. It was a problem for the health care providers that CRF could not be treated with a single, simple and effective intervention, so they opted for interdisciplinary collaboration and an integrative treatment program when approaching the treatment of CRF. A nurse expert expressed the need for approaches at different levels, including the physical, emotional, mental and spiritual levels.

Many stakeholders also reflected on the goal of CRF treatment, which they saw as increasing the energy level of the patients, improving their quality of life and helping them adopt coping strategies. A nurse expert differentiated between patients in curative and palliative situations. To her, the goal in palliative patients should be “coping” (nurse expert) and “managing their own energy levels” (nurse expert) throughout the day, whereas in a curative setting, the patients should aim to regain their energy mainly by exercising. Most stakeholders stressed that one of the most important goals is to provide patients with options that help them regain trust in their own bodies and in their abilities, as many cancer patients lose faith in their own bodies. For the stakeholders, this was also strongly linked with the topic of regaining self-efficacy. The stakeholders thought that this could be best achieved by exercising and by psychoeducation. However, it is a major challenge for people with CRF to become active on a regular basis because being active and experiencing CRF are contradictory in their nature. The stakeholders differed in their views on how to approach this challenge. Whereas some patients would have preferred personal coaching with an individual workout program, a few health care providers opted for group trainings tailored for CRF patients, with the focus not only on the financial and infrastructural feasibility but also on the possible benefits of the group setting, such as sharing similar diagnoses, exchanging experiences and motivating each other.

Attitude

The stakeholders agreed on the attitudes of the patients and health care providers needed for a successful integrative CRF treatment program. The treatment approach should be patient-oriented, should focus on self-care options and should create possibilities for self-management for the patients. According to the stakeholders, a patient-oriented approach is also needed to strengthen patients’ self-efficacy and to overcome feelings of helplessness that often go along with experiencing a life-threatening disease such as cancer.

The nurses and nurse experts stressed that an individualized approach is needed. This would consider patients’ cultural and social backgrounds as well as their individual experiences with their cancer and with CRF, recognizing the importance of connecting with the patients’ resources and interests.

The patients unanimously agreed with the patient orientation, but also wished to be simultaneously informed, monitored and accompanied by health care providers because they felt unable to act completely autonomously while experiencing deep exhaustion and fatigue. They often felt they were being left alone with their CRF, especially after active cancer treatment.

Some health care providers pointed out that an integrative approach and a focus on self-care often require a change in health behavior in the patient and that this is a serious challenge while experiencing cancer and CRF.

Infrastructure, time-management, costs and affordability

The health care providers identified a need for a multimodal approach to treat CRF and talked about the consequences that come along with such an approach. First, hospitals are always short of manpower, infrastructure and time to meet all the different needs of individual patients. In addition, it is a challenge to coordinate the treatment between different departments and ensure the flow of information between all involved parties. Some stakeholders imagined a “shopping-center” (medical oncologist) or “drop-in-center” (medical oncologist) where the different treatments would be coordinated, monitored and located in the same building.

Normally, cancer patients have many appointments that can result in an overload of consultations and therapies. Consequently, most stakeholders opted for a prioritization of treatments – also based on the severity of CRF in the individual patient – and a focus on options that could be executed at home, such as exercising or acupressure. According to the stakeholders, prioritizing is even more important for CRF patients because they experienced these patients to be very restricted on all levels. Too many appointments limit the processing of information and interventions in CRF patients. Therefore, a good organization of the appointments is needed as well as locating therapies within a comfortable geographical distance from where the patients live. In addition, some stakeholders pointed to the challenge of coordinating work with an extensive treatment program, as is often the case in cancer patients.

The stakeholders agreed that the integrative treatment program would be most feasible if it would be fully covered by public health insurance. Admission into public health insurance usually requires standard diagnostic tools and evidence from good quality randomized controlled clinical trials for the interventions; both would be currently available. However, there were also some opinions from health care providers that patients should pay privately to increase their adherence to the treatment program. Simultaneously, they opted for establishing a “social welfare fund for cases of hardship” (medical oncologist). The nurse experts pointed out that cancer survivors usually struggle financially because they have lost their jobs or cannot work anymore because of their cancer.

Integrative approach

All patients wished to have an integrative approach to their therapies. They asked their medical doctors or nurses about what complementary medicine (CM) interventions they could add to their therapy.

In general, the health care providers considered CM approaches as especially supportive for their patients, contributing actively to their recoveries. They noticed a growing awareness in medical doctors and hospital environments of the possibility of adopting an integrative approach and referring patients to the respective institutions. However, patients complained about a lack of interdisciplinary collaboration between the different health care providers.

The health care providers did not have the impression that their patients followed a coordinated integrative treatment program at the time of the interviews. Instead, they experienced isolated applications of single CM interventions in their patients, such as yoga, diets or phytomedicine, which had been recommended to the patients by their private environments or were found on the internet.

The health care providers themselves only recommended CM interventions for which they personally had a clear idea of the benefits. Some of them adopted a stance of not believing in certain interventions but thinking “even if it is not effective, it does not harm” (nurse expert). Some health care providers were critical about the effectiveness of CM interventions and opted for strict “academic, scientific, evidence-based complementary medicine” (radiation-oncologist).

First experiences with the implementation of the integrative CRF treatment program in our clinic point to the program being feasible if patients come into the clinic with CRF as their main complaint. However, more often, CRF is one of many complaints that cancer patients report when coming to our clinic. Our medical doctors then prioritize the interventions with the patients. Exercising and mind-body medicine techniques are discussed with every CRF patient. Then, usually one other intervention from the program for CRF is selected, often acupuncture or acupressure. In addition, procedures or remedies which cover both CRF and the patients’ other symptoms are selected, such as mistletoe extract or other herbal drugs.

Discussion

Table 3 provides a summary of barriers and facilitators regarding the feasibility of treating CRF in supportive care in hospital environments in the views of the stakeholders.

Table 3 Summary of barriers and facilitators regarding the feasibility of treating CRF in supportive care in hospital environments in the views of the stakeholders

Although all the discussed topics are linked to different challenges of making the suggested integrative treatment program feasible for CRF, we identified two major challenges out of the interviews with the stakeholders: first, staff and financial resources, and second, the coordination of such a multimodal, interprofessional approach in terms of infrastructure, flow of information and manageable organization. To date, supportive cancer therapies are still heavily competing with antineoplastic therapies for limited health care funding [20]. As the financial burden of cancer care increases in the future [21,22,23], health care funding remains a major challenge for supportive cancer therapies. Increasing reimbursement for supportive therapies would require a considerable shift in the rating of the importance of supportive care compared to antineoplastic therapies by governments, health care policy makers and investors [20, 24]. However, as cancer survivors are a rapidly growing population, awareness of the need for supportive cancer therapies increases simultaneously. Not only the financial burden of cancer disease in patients has to be considered, but also the cognitive, physical, emotional and spiritual burdens and their impacts on productivity, citizenship and contribution to society [20, 25]. Apparently, there is no global solution either for solving infrastructural problems or for the coordination of a multimodal treatment approach and interprofessional collaboration. There is a broad consensus that interprofessional collaboration in supportive cancer care ideally must entail a united team effort of “medical, nursing, psycho-social and spiritual support into a global and anticipated team approach to the patients and their social environment” ([26], p.10). However, practical solutions must be found and implemented locally, ensuring the transfer of knowledge and professional expertise [25, 27]. To overcome the gap between research and implementation into practice, key stakeholders – including scientists, health care policy makers, funders, health professionals, advocacy groups, patients and caregivers – have to collaborate on the basis of “trust, mutual respect and shared responsibility” ([25] , p.580).

Potential approaches

In our clinic, we address these challenges in various ways. As we are part of the University Hospital Zurich all our supportive cancer care interventions are covered by the public health insurance. This enables almost all patients to have access to our treatment options. We handle the challenge of the coordination of such a multimodal, interprofessional approach in different ways. We built an interdisciplinary team of medical doctors with different integrative medicine expertise, psychotherapists, nurses and a nutritionist in our clinic. The whole clinical team regularly meets for case conferences where the treatment of single patients is discussed and coordinated.

A promising attempt to approach the challenge of a globally standardized treatment of CRF is the implementation of evidence-based guidelines for CRF management, such as the NCCN guideline [1] or the CAPO guideline [28]. Assessments of the guidelines showed that they face similar problems concerning their feasibility: availability of the guidelines and diagnostic tools, education of health professionals and patients, coordination of an interprofessional team, integration with existing practices and patient-orientation (e.g. [29]).

Strengths and limitations

The study has strengths and limitations. We gathered the experiences and views of CRF patients and included other key stakeholders, such as health care providers or patient family members, to obtain a broader perspective towards an integrative treatment approach to CRF, especially considering the contextual factors that influence the feasibility of treating CRF. In addition, we adopted a participatory approach by working with a stakeholder advisory board. A limitation of the study is that not all stakeholders were equally included, and some were even missing completely, such as allied health practitioners, hospital administrators or health insurance representatives. Other stakeholders might have provided a broader perspective. Another limitation is that we conducted the study in a hospital environment that might not be applicable to other health care environments.

Future research should include the scientific evaluation of the integrative treatment program for CRF, addressing especially the relevant contextual factors, infrastructure, resources, cost-effectiveness and interprofessional collaboration.

Conclusion

Key factors of a feasible treatment approach to CRF are a coherent, cost effective integrative treatment program facilitated by an interdisciplinary team of health care providers. Ideally, such a program should entail a coordinated monitoring of the treatment of the patients. Furthermore, the treatment approach should be patient orientated. Adopting an individualized approach, health care providers should aim at self-efficacy of the patients.

Despite the numerous barriers, a clinic of integrative medicine embedded in a hospital environment and with a focus on supportive cancer care has the potential of realizing such a feasible integrative treatment program for CRF.
