Cancer-related fatigue: appraising evidence-based guidelines for screening, assessment and management

A systematic mapping review of clinical guidelines for the management of fatigue in long-term physical health conditions

PURPOSE

Despite a high prevalence of fatigue and its importance to patients, many people with long-term conditions do not receive fatigue management as part of their treatment. This review is aimed to identify clinical guidance for the management of fatigue in long-term physical health conditions.

METHODS

A systematic mapping review was conducted in accordance with Social Care Institute for Excellence systematic review guidance. Bibliographic databases and guideline repositories were searched for clinical guidelines for long-term conditions, published between January 2008 and July 2018, with a search for updates conducted in May 2023. Data were extracted on the recommendations made for managing fatigue and, where cited, the underlying research evidence used to support these recommendations was also extracted.

RESULTS

The review included 221 guidelines on 67 different long-term conditions. Only 30 (13.6%) of the guidelines contained recommendations for managing fatigue. These were categorised as clinical (e.g. conduct further investigations), pharmacological, behavioural (e.g. physical activity), psychological, nutritional, complementary, environmental, and multicomponent. The guidelines rated much of the evidence for fatigue management as fairly low quality, highlighting the need to develop and test fatigue-management strategies in high-quality trials.

CONCLUSION

This review highlights that management of fatigue is a very important neglected area in the clinical guidelines for managing long-term conditions.

Identifying strategies for implementing a clinical guideline for cancer-related fatigue: a qualitative study

BACKGROUND

Clinical practice guidelines assist health professionals' (HPs) decisions. Costly to develop, many guidelines are not implemented in clinical settings. This paper describes an evaluation of contextual factors to inform clinical guideline implementation strategies for the common and distressing problem of cancer-related fatigue (CRF) at an Australian cancer hospital.

METHODS

A qualitative inquiry involving interviews and focus groups with consumers and multidisciplinary HPs explored key Canadian CRF guideline recommendations. Four HP focus groups examined the feasibility of a specific recommendation, while a consumer focus group examined experiences and preferences for managing CRF. Audio recordings were analysed using a rapid method of content analysis designed to accelerate implementation research. Strategies for implementation were guided by the Consolidated Framework for Implementation Research.

RESULTS

Five consumers and 31 multidisciplinary HPs participated in eight interviews and five focus groups. Key HP barriers to fatigue management were insufficient knowledge and time; and lack of accessible screening and management tools or referral pathways. Consumer barriers included priority for cancer control during short health consultations, limited stamina for extended or extra visits addressing fatigue, and HP attitudes towards fatigue. Enablers of optimal fatigue management were alignment with existing healthcare practices, increased HP knowledge of CRF guidelines and tools, and improved referral pathways. Consumers valued their HPs addressing fatigue as part of treatment, with a personal fatigue prevention or management plan including self-monitoring. Consumers preferred fatigue management outside clinic appointments and use of telehealth consultations.

CONCLUSIONS

Strategies that reduce barriers and leverage enablers to guideline use should be trialled. Approaches should include (1) accessible knowledge and practice resources for busy HPs, (2) time efficient processes for patients and their HPs and (3) alignment of processes with existing practice. Funding for cancer care must enable best practice supportive care.

Psychosocial Interventions for the Treatment of Cancer-Related Fatigue: An Umbrella Review

Cancer-related fatigue is one of the most common symptoms of cancer and one of those referred by patients as the most disabling. However, we still do not have enough evidence to allow us to recommend effective and personalized approaches. Goal: To provide evidence on the efficacy of ASCO-recommended psychosocial interventions for reducing cancer-related fatigue. Methodology: A general quantitative systematic review for nonprimary clinical interventions that allows the collection, synthesis and analysis of already published reviews. Systematic reviews of RTCs were selected as these make up the body of knowledge that provides the most evidence in an umbrella format. The results do not provide clear or comparable evidence regarding the different interventions, with moderate evidence standing out for cognitive interventions and mindfulness. Conclusions: Research gaps, study biases and the need for further research to ask more precise questions and to make reliable recommendations to mitigate the impact of cancer-related fatigue are evident.

Screening and Assessment of Cancer-Related Fatigue: A Clinical Practice Guideline for Health Care Providers

Cancer-related fatigue (CRF) is the most common side effect of cancer treatment. Regular surveillance is recommended, but few clinical practice guidelines transparently assess study bias, quality, and clinical utility in deriving recommendations of screening and assessment methods. The purpose of this clinical practice guideline (CPG) is to provide recommendations for the screening and assessment of CRF for health care professions treating individuals with cancer. Following best practices for development of a CPG using the Appraisal of Guidelines for Research and Evaluation (AGREE) Statement and Emergency Care Research Institute (ECRI) Guidelines Trust Scorecard, this CPG included a systematic search of the literature, quality assessment of included evidence, and stakeholder input from diverse health care fields to derive the final CPG. Ten screening and 15 assessment tools supported by 114 articles were reviewed. One screen (European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire-30 Core Questionnaire) and 3 assessments (Piper Fatigue Scale-Revised, Functional Assessment of Chronic Illness Therapy-Fatigue, and Patient Reported Outcome Measurement Information System [PROMIS] Fatigue-SF) received an A recommendation ("should be used in clinical practice"), and 1 screen and 5 assessments received a B recommendation ("may be used in clinical practice"). Health care providers have choice in determining appropriate screening and assessment tools to be used across the survivorship care continuum. The large number of tools available to screen for or assess CRF may result in a lack of comprehensive research evidence, leaving gaps in the body of evidence for measurement tools. More research into the responsiveness of these tools is needed in order to adopt their use as outcome measures.

IMPACT

Health care providers should screen for and assess CRF using one of the tools recommended by this CPG.

Nurse-Led Consultation and Symptom Burden in Patients with Head and Neck Cancer: A Comparative Analysis of Routine Clinical Data

Background: Head and neck cancer (HNC) patients experience distressing symptoms that can significantly impact their health-related quality of life (HRQoL). We analyzed the implementation of a nurse-led consultation (NLC) and explored potential associations with symptom burden in HNC patients. Methods: We retrospectively analyzed routinely collected data to describe the implementation of the nurse-led interventions and the evolution of the M.D. Anderson Symptom Inventory scores as patient-reported outcome measures (PROMs). Patients who received routine care (n = 72) were compared with patients in the NLC group (n = 62) at a radiation oncology unit between 2017 and 2019. PROMs were measured at T0 (between simulation and the first week of radiotherapy), T1 (week 3−4), and T2 (week 5−6). Results: Screening for nutrition, smoking, oral cavity status, and capacity for swallowing/chewing, but not for pain, was applied in >80% of patients in the NLC group from T0 to T1. Education (16%) and care coordination (7%) were implemented to a lesser extent. Symptom burden increased over time with no significant differences between groups. Conclusions: The nurse-led consultation was not associated with symptom burden over time. A larger implementation study including a detailed process evaluation, larger sample size, and a focus on long-term effects is needed.

Persistent fatigue among long-term non-Hodgkin lymphoma survivors

This study describes the prevalence and persistence of fatigue among a cohort of long-term non-Hodgkin lymphoma (NHL) survivors. Mailed surveys assessed quality-of-life including fatigue (SF-36) at baseline and five years. Logistic regression was used to identify factors associated with prevalence of fatigue at baseline and persistence of fatigue across timepoints. More than one-quarter (27.7%) of the 555 NHL survivors reported clinically meaningful fatigue at baseline and 18.7% reported persistent fatigue at five years. One-third (34.4%) reported clinically meaningful worsening of fatigue over time. Independent associations with persistent fatigue included female gender, less education, past chemotherapy, increased comorbidities, and posttraumatic stress symptoms (P <.05). Our findings suggest that one in three NHL survivors experience clinically meaningful fatigue long after their diagnosis and initial treatment. Furthermore, we found that fatigue worsens or persists for many, highlighting the need for vigilance in assessing and treating fatigue in this population.

Effects of traditional Chinese medicine exercise therapy on cancer-related fatigue, anxiety and sleep quality in cancer patients: A protocol for systematic review and network meta-analysis

BACKGROUND

Cancer-related fatigue (CRF) is one of the most common adverse events of anticancer therapies, with an incidence of up to 90%, which seriously affects the quality of life in cancer patients. Complementary and alternative therapies for CRF include acupuncture, Chinese herbal medicine, Tai Chi, Qigong, and massage therapy. Several studies have shown that traditional Chinese medicine (TCM) exercise therapies, such as Tai Chi, Ba Duan Jin, the classics of tendon changing, Six Healing Sounds, and Wu Qin Xi, can improve CRF, anxiety symptoms, and sleep quality in cancer patients. However, their specific efficacy and which TCM exercise therapy is the best remain controversial. In this study, we assess and compare the effects of different TCM exercise therapies on CRF, anxiety, and sleep quality in cancer patients by network meta-analysis (NMA).

METHODS

Randomized controlled trials reporting TCM exercise therapies for CRF, anxiety and sleep quality in cancer patients published before October 2021 will be searched in the PubMed, Web of Science, Scopus, Cochrane Library, Embase, China Scientific Journal Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, and Wanfang Data. Two researchers will be independently responsible for literature screening, data extraction and assessment of their quality. Standard pair-wise and NMA will be performed to compare the efficacy of different TCM exercise therapies on CRF, anxiety and sleep quality in cancer patients using Stata 14.0 software.

RESULTS

The results of this meta-analysis will be submitted to a peer-reviewed journal for publication.

CONCLUSIONS

This NMA will contribute to identify the optimal TCM exercise therapy for CRF and provide evidence-based bias for clinical decision-making.

ETHICS AND DISSEMINATION

Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms.

Building a biopsychosocial model of cancer-related fatigue: the BIOCARE FActory cohort study protocol

Background

Cancer-related fatigue (CRF) is the most common side effect of cancer and cancer treatment. CRF prevalence is up to 50% in breast cancer patients and can continue several years after cancer remission. This persistent subjective sense of exhaustion is multifactorial. Numerous parameters have been evidenced to be related to CRF across biological, physical, psychological, social and/or behavioral dimensions. Although CRF has been studied for many years, the majority of previous studies focused on only one dimension, i.e., physical function. Moreover, few studies investigated CRF longitudinally with repeated measures. These are the two main obstacles that limit the understanding of CRF mechanisms. The purpose of this study is to create a biopsychosocial model of CRF with simultaneous and longitudinal anthropometric, clinical, biological, physical, psychological and sociological parameters.

Methods

BIOCARE FActory is a multicentric prospective study that will consist of an 18-month follow-up of 200 women diagnosed with breast cancer. Four visits will be scheduled at diagnosis, after treatments, and 12 and 18 months after diagnosis. The same procedure will be followed for each visit. Each session will be composed of anthropometric data collection, a semi-structured interview, cognitive tests, postural control tests, neuromuscular fatigability tests and a cardiorespiratory fitness test. Clinical and biological data will be collected during medical follow-ups. Participants will also complete questionnaires to assess psychological aspects and quality of life and wear an actigraphy device. Using a structural equation modeling analysis (SEM), collected data will build a biopsychosocial model of CRF, including the physiological, biological, psychological, behavioral and social dimensions of CRF.

Discussion

This study aims to highlight the dynamics of CRF and its correlates from diagnosis to post treatment. SEM analysis could examine some relations between potential mechanisms and CRF. Thus, the biopsychosocial model will contribute to a better understanding of CRF and its underlying mechanisms from diagnosis to the aftermaths of cancer and its treatments.

Trial registration

This study is registered at ClinicalTrials.gov (NCT04391543), May 2020.

Nursing management of fatigue in cancer patients and suggestions for clinical practice: a mixed methods study

Background

Fatigue is a complex and frequent symptom in cancer patients, influencing their quality of life, but it is still underestimated and undertreated in clinical practice. The aims of this study were to detect the presence of fatigue in cancer patients, describe how patients and nurses perceived it and how nurses managed fatigue.

Methods

This is a mixed methods study. Data were collected in two oncological wards using the Brief Fatigue Inventory (BFI), an ad hoc questionnaire, patient interviews, focus groups with nurses and the review of nursing records. Interviews and focus groups were analysed through thematic analysis. We used SPSS 22.0 for quantitative data and Nvivo 10 for qualitative data analysis.

Results

A total of 71 questionnaires were analysed (39 males, mean age 65.7 years). Fatigue was reported 5 times (7%) in nursing records, while in 17 cases (23.9%) problems associated to it were reported. Twelve patients were interviewed. Five themes were identified: feeling powerless and aggressive, my strategies or what helps me, feeling reassured by the presence of family members, feeling reassured by nurses’ gestures, and being informed. Three themes were identified through the focus groups: objectivity and subjectivity in the assessment of fatigue, nurses’ contribution to the multidisciplinary management of fatigue, and difficulty in evaluating outcomes.

Conclusions

The approach to the management of fatigue was unstructured. Patients were satisfied with the care they received but needed more information and specific interventions. Useful aspects were identified that could be used to change health professionals’ approach towards the management of fatigue.

[An updated synthesis of the international recommendations about the use of non-pharmacological interventions in the treatment of fatigue]

INTRODUCTION

Fatigue is a frequent and disturbing symptom in oncology but remains undertreated. Given the absence of effective drug treatment, non-pharmacological interventions have a prominent place in the treatment of fatigue. However, they are relatively unknown by professionals who lack of clear points of reference to refer patients with confidence. This article aims to improve the knowledge about this therapeutic field through an updated synthesis of the levels of recommendations and available evidence.

METHODS

A three-step approach was conducted, including (1) a synthesis of international guidelines on non-pharmacological interventions in the treatment of fatigue among adults in oncology, (2) a systematic review of recent data in the literature, (3) a comparison between the synthesis of guidelines and the systematic review with the aim of updating the levels of evidence.

RESULTS

Five guidelines were synthesized; 111 systematic reviews were analyzed. Their comparison mainly showed: (1) a convergence in favor of the use of physical activity, educational interventions and cognitive-behavioral therapies, with levels of evidence ranging from moderate to high; (2) a consolidation of short-term efficacy evidence to support the use of mindfulness-based approaches and yoga; 3) the persistence of a lack of sufficiently reliable data to establish the efficacy of other types of intervention.

DISCUSSION

Supported by international guidelines and recent data, the use of non-pharmacological interventions in the treatment of fatigue is critical and has to become better known.

Neuromuscular, Psychological, and Sleep Predictors of Cancer-Related Fatigue in Cancer Patients

BACKGROUND

Cancer-related fatigue (CRF) is the most reported side effect of cancer and its treatments. This distressing sense of exhaustion critically impairs quality of life and can persist for years after treatment completion. Mechanisms of CRF are multidimensional (eg, physical, psychological, or behavioral), suggesting the need for a complex assessment. Nevertheless, CRF remains assessed mainly with 1-dimensional questionnaires. The purpose of this study was to test whether neuromuscular parameters enhance a model including well-known predictors of CRF.

PATIENTS AND METHODS

Forty-five participants with cancer history completed self-assessment questionnaires about quality of life, CRF, sleep disturbances, and emotional symptoms. They also completed a 5-minute handgrip fatiguing test composed of 60 maximal voluntary contractions to assess neuromuscular fatigability. Hierarchical linear regression analyses were performed to determine whether the neuromuscular fatigability threshold improved the FA12 score prediction beyond that provided by anxiety/depression and sleep disturbances.

RESULTS

The hierarchical linear regression analysis evidenced that a model including anxiety/depression, sleep disturbances, and neuromuscular fatigability explained 56% of CRF variance. In addition, the results suggest that the mechanisms leading to CRF may be different from one person to another.

CONCLUSION

Results revealed that sleep disturbances, emotional symptoms, and neuromuscular fatigability were the most important CRF predictors in cancer patients. This information could be useful for healthcare professionals offering tailored, individual support to patients with CRF.

A perfect storm and patient-provider breakdown in communication: two mechanisms underlying practice gaps in cancer-related fatigue guidelines implementation

PURPOSE

Cancer-related fatigue (CRF) is a debilitating symptom experienced by many cancer patients. Although guidelines provide evidence-based recommendations for screening, assessing, and managing CRF, there is limited evidence of their implementation in practice. This study aimed to explore patients', healthcare providers' (HCPs), community support providers' (CSPs) experiences and opinions on CRF guidelines and the underlying causes of CRF treatment gaps following the Knowledge-to-Action model.

METHODS

A total of 62 participants were recruited-16 patients, 32 HCPs, and 14 CSPs-for a total of 9 focus groups and 4 individual interviews. Sessions were recorded and transcribed verbatim. Transcripts were analyzed using thematic analysis.

RESULTS

There were gaps in the application of CRF guidelines and patient dissatisfaction with care. Two underlying mechanisms may contribute to these gaps. First, professionals' lack of knowledge and resources paired with systemic obstacles created difficult conditions to adequately address CRF-A Perfect Storm. Further, patient-provider communication gaps lead to patients feeling discouraged to report issues to their healthcare teams and turning to community services for help-A Breakdown in Communication.

CONCLUSIONS

There is little indication that CRF guidelines are routinely implemented in clinical practice. This study provides insights from various perspectives to aid understanding of the critical issues that require consideration to increase implementation of CRF guidelines by HCPs. As patients are currently dissatisfied with CRF-related care, implementation of CRF guidelines is needed.

Post-exertional Malaise in People With Chronic Cancer-Related Fatigue

CONTEXT

Cancer-related fatigue (CRF) is a distressing and persistent sense of tiredness or exhaustion that interferes with usual functioning. Chronic CRF continues for months after curative cancer treatment is complete. Post-exertional malaise (PEM) is a worsening of symptoms after physical or mental activity, with limited investigations in people with chronic CRF.

OBJECTIVES

The purpose of this study was to identify and describe self-reported incidences of PEM in people with chronic CRF.

METHODS

Participants (n = 18) were eligible if they scored ≤34 on the Functional Assessment of Chronic Illness Therapy-Fatigue scale and had a cancer-related onset of fatigue. Participants completed a brief questionnaire to assess PEM during a six-month time frame (the DePaul Symptom Questionnaire-PEM). In addition, a maximal exercise test was used to investigate self-reported symptom exacerbation (via an open-ended questionnaire) after strenuous physical exertion.

RESULTS

On the DePaul Symptom Questionnaire-PEM, three participants met previously defined scoring criteria, which included experiencing moderate to very severe symptoms at least half of the time, worsening of fatigue after minimal effort, plus a recovery duration of >24 hours. Content analysis of responses to open-ended questionnaires identified five people who experienced a delayed recovery and symptoms of PEM after maximal exercise.

CONCLUSION

A subset of people with chronic CRF (up to 33% in this sample) may experience PEM. Exercise specialists and health care professionals working with people with chronic CRF must be aware that PEM may be an issue. Symptom exacerbation after exercise should be monitored, and exercise should be tailored and adapted to limit the potential for harm.

[Fatigue after head and neck cancer-results of a survey using the Multidimensional Fatigue Inventory (MFI-20)]

BACKGROUND

Fatigue resulting from cancer and its treatment can lead to a reduction in quality of life. The frequency and intensity of fatigue syndrome after cancer therapy in the ENT field are largely unknown. Therefore, during follow-up consultations, the authors conducted a random survey with the help of the Multidimensional Fatigue Inventory (MFI 20).

METHODS

During aftercare consultations, 66 patients were interviewed (average age 63 years, 21 women). All patients had received radiotherapy an average of 2 years previously (range 1-4 years). All respondents were in full remission at the time of the survey. According to recommendations, evaluation of the MFI-20 was carried out in 5 subgroups: general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue. For comparison with standard values, respondents were grouped by age into under and over 60 years and were also evaluated by gender.

RESULTS

Regardless of gender, our patients reported clearly elevated scores in all subgroups. Particularly participants aged under 60 years reported very high scores. The clarity of the results surprised the authors.

CONCLUSION

Fatigue represents a very profound and prolonged impairment for the patients of our study. Since fatigue can still be present a long time after completion of treatment, patients should be asked about it specifically using a standardized inventory during follow-up. In order to cope with fatigue syndrome, specific therapeutic recommendations aimed at activation, such as regular physical activity, nutritional advice, and complementary measures, can be made.

Translating guidelines to practice: a training session about cancer-related fatigue

Background

Cancer-related fatigue (crf) is the highest unmet need in cancer survivors. The Canadian Association of Psychosocial Oncology (capo) has developed guidelines for screening, assessment, and intervention in crf; however, those guidelines are not consistently applied in practice because of patient, health care provider (hcp), and systemic barriers. Notably, previous studies have identified a lack of knowledge of crf guidelines as an impediment to implementation.

Methods

In this pilot study, we tested the preliminary outcomes, acceptability, and feasibility of a training session and a knowledge translation (kt) tool designed to increase knowledge of the capo crf guidelines among hcps and community support providers (csps). A one-time in-person training session was offered to a diverse sample of hcps and csps (n = 18). Outcomes (that is, knowledge of the capo crf guidelines, and intentions and self-efficacy to apply guidelines in practice) were assessed before and after training. Acceptability and feasibility were also assessed after training to guide future testing and implementation of the training.

Results

After training, participants reported increased knowledge of the capo crf guidelines and greater self-efficacy and intent to apply guidelines in practice. Participant satisfaction with the training session and the kt tool was high, and recruitment time, participation, and retention rates indicated that the training was acceptable and feasible.

Conclusions

The provided training is both acceptable to hcps and csps and feasible. It could increase knowledge of the capo crf guidelines and participant intentions and self-efficacy to implement evidence-based recommendations. Future studies should investigate actual changes in practice and how to optimize follow-up assessments. To promote practice uptake, kt strategies should be paired with guideline development.

Healthcare professionals knowledge on cancer-related fatigue: A cross-sectional survey in Oman

Cancer-related fatigue is a common and distressing cancer symptom that negatively affects quality of life. The main objective of this study was to determine health professionals' knowledge relating to cancer patients' fatigue in Oman and identify current management practices of cancer-related fatigue. A cross-sectional survey design using Qualtrics® software was performed. The survey had five sections and comprised 32 items. A total of 138 healthcare professionals working in Oman participated in the study (response rate 63.9%). Nearly three quarters of the participants were nurses (74.6%, n = 103). The mean level of knowledge of cancer-related fatigue was 16.6/23, with 50% of participants having the expected level of knowledge above 12. The result indicated that professional discipline and work experience each were significantly associated with overall level of knowledge. Participants identified the need for guidelines, assessment tools, and training for the oncology staff to help improve the quality of life of patients with cancer-related fatigue.

Fatigue, a major still underestimated issue

PURPOSE OF REVIEW

Cancer-related fatigue (CRF) is a frequent and distressing symptom present at any stage of the disease. However, it is still underreported, rarely properly assessed and undertreated.

RECENT FINDINGS

There are international guidelines available, but also several barriers to their implementation into clinical practice.

SUMMARY

According to guidelines, all patients should be clinically screened for CRF on regular basis, at the initial cancer visit and at intervals during every clinic visit, also at posttreatment follow-up visits. Generally, any treatable contributing factors should be identified and possibly treated. After the concomitant factors have been improved or removed, pharmacological and or nonpharmacological treatments of CRF can be considered.Further research is needed to better understand the causes, the better treatments, the easier assessment tool for CRF for clinical practice and to identify barriers and facilitators to implementing CRF guidelines.

Cancer related fatigue: implementing guidelines for optimal management

Background

Cancer-related fatigue (CRF) is a key concern for people living with cancer and can impair physical functioning and activities of daily living. Evidence-based guidelines for CRF are available, yet inconsistently implemented globally. This study aimed to identify barriers and enablers to applying a cancer fatigue guideline and to derive implementation strategies.

Methods

A mixed-method study explored the feasibility of implementing the CRF guideline developed by the Canadian Association for Psychosocial Oncology (CAPO). Health professionals, managers and consumers from different practice settings participated in a modified Delphi study with two survey rounds. A reference group informed the design of the study including the surveys. The first round focused on guideline characteristics, compatibility with current practice and experience, and behaviour change. The second survey built upon and triangulated the first round.

Results

Forty-five health practitioners and managers, and 68 cancer survivors completed the surveys. More than 75% of participants endorsed the CAPO cancer related fatigue guidelines. Some respondents perceived a lack of resources for accessible and expert fatigue management services. Further barriers to guideline implementation included complexity, limited practical details for some elements, and lack of clinical tools such as assessment tools or patient education materials. Recommendations to enhance guideline applicability centred around four main themes: (1) balancing the level of detail in the CAPO guideline with ease of use, (2) defining roles of different professional disciplines in CRF management, (3) how best to integrate CRF management into policy and practice, (4) how best to ensure a consumer-focused approach to CRF management.

Conclusions

Translating current knowledge on optimal management of CRF into clinical practice can be enhanced by the adoption of valid guidelines. This study indicates that it is feasible to adopt the CAPO guidelines. Clinical application may be further enhanced with guideline adaptation, professional education and integration with existing practices.

Exploration of the methodological quality and clinical usefulness of a cross-sectional sample of published guidance about exercise training and physical activity for the secondary prevention of coronary heart disease

BACKGROUND

Clinicians are encouraged to use guidelines to assist in providing evidence-based secondary prevention to patients with coronary heart disease. However, the expanding number of publications providing guidance about exercise training may confuse cardiac rehabilitation clinicians. We therefore sought to explore the number, scope, publication characteristics, methodological quality, and clinical usefulness of published exercise-based cardiac rehabilitation guidance.

METHODS

We included publications recommending physical activity, exercise or cardiac rehabilitation for patients with coronary heart disease. These included systematically developed clinical practice guidelines, as well as other publications intended to support clinician decision making, such as position papers or consensus statements. Publications were obtained via electronic searches of preventive cardiology societies, guideline databases and PubMed, to November 2016. Publication characteristics were extracted, and two independent assessors evaluated quality using the 23-item Appraisal of Guidelines Research and Evaluation II (AGREE) tool.

RESULTS

Fifty-four international publications from 1994 to 2016 were identified. Most were found on preventive cardiology association websites (n = 35; 65%) and were freely accessible (n = 50; 93%). Thirty (56%) publications contained only broad recommendations for physical activity and cardiac rehabilitation referral, while 24 (44%) contained the necessary detailed exercise training recommendations. Many were labelled as "guidelines", however publications with other titles (e.g. scientific statements) were common (n = 24; 44%). This latter group of publications contained a significantly greater proportion of detailed exercise training recommendations than clinical guidelines (p = 0.017). Wide variation in quality also existed, with 'applicability' the worst scoring AGREE II domain for clinical guidelines (mean score 53%) and 'rigour of development' rated lowest for other guidance types (mean score 33%).

CONCLUSIONS

While a large number of guidance documents provide recommendations for exercise-based cardiac rehabilitation, most have limitations in either methodological quality or clinical usefulness. The lack of rigorously developed guidelines which also contain necessary detail about exercise training remains a substantial problem for clinicians.
