Web-based cognitive rehabilitation for survivors of adult cancer: A randomised controlled trial

Systematic review and meta-analysis of standalone digital interventions for cognitive symptoms in people without dementia

Cognitive symptoms are prevalent across neuropsychiatric disorders, increase distress and impair quality of life. Self-guided digital interventions offer accessibility, scalability, and may overcome the research-to-practice treatment gap. Seventy-six trials with 5214 participants were identified. A random-effects meta-analysis investigated the effects of all digital self-guided interventions, compared to controls, at post-treatment. We found a small-to-moderate positive pooled effect on cognition (k = 71; g = -0.51, 95%CI -0.64 to -0.37; p < 0.00001) and mental health (k = 30; g = -0.41, 95%CI -0.60 to -0.22; p < 0.0001). Positive treatment effects on fatigue (k = 8; g = -0.27, 95%CI -0.53 to -0.02; p = 0.03) and quality of life (k = 22; g = -0.17, 95%CI -0.34 to -0.00; p = 0.04) were only marginally significant. No significant benefit was found for performance on activities of daily living. Results were independent of control groups, treatment duration, risk of bias and delivery format. Self-guided digital transdiagnostic interventions may benefit at least a subset of patients in the short run, yet their impact on non-cognitive outcomes remains uncertain.

Impact of Cognitive Rehabilitation on Cognitive and Functional Outcomes in Adult Cancer Survivors: A Systematic Review

OBJECTIVES

This systematic review (PROSPERO CRD42021275421) synthesized evidence on the efficacy of cognitive rehabilitation on cognitive and functional outcomes in adult cancer survivors.

METHODS

Articles were identified though PubMed/MEDLINE, EMBASE, PsycINFO, and Web of Science from inception through June 30, 2023. Studies included participants ≥18 years old, diagnosed with cancer. Primary outcomes were validated measures of subjective and objective cognition. Articles were dual reviewed for eligibility and data extraction. Risk of bias was assessed with the Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields.

RESULTS

The search yielded 3,811 articles; 65 full-text articles were reviewed; 53 articles (15 cognitive training, 14 strategy-based, 21 combinations, three inpatient rehabilitation), representing 52 unique studies, were included. Positive effects were observed in at least one objective cognitive measure in 93% of strategy training, 81% of cognitive training, 79% of combination rehabilitation interventions. Positive effects were observed in subjective cognition in 100% of strategy training, 55% of cognitive training, and 92% of combination interventions. Among studies with comparator groups, processing speed improved in 60% of cognitive training studies, while strategy training did not improve processing speed; otherwise, cognitive domain effects were similar between intervention types. Impact on functional outcomes was inconclusive.

CONCLUSIONS

Cognitive rehabilitation appear beneficial for cancer-related cognitive impairment (CRCI). Differential effects on specific cognitive domains (eg, processing speed) and subjective cognition may exist between intervention types.

IMPLICATIONS FOR NURSING PRACTICE

Nurses should increase patient and provider awareness of the benefits of cognitive rehabilitation for CRCI.

Online Group Cognitive Rehabilitation Program for Prostate Cancer Survivors: Development Using Codesign and the Theoretical Domains Framework

OBJECTIVES

This study aimed to describe the adaptation of a group cognitive rehabilitation program for prostate cancer survivors (PCS) via telehealth delivery using a codesign approach with PCS experiencing cancer-related cognitive impairment. The Theoretical Domains Framework (TDF) also informed the intervention development.

METHODS

Intervention development consisted of three steps: 1) Adapting an existing cancer-related cognitive rehabilitation program for PCS; 2) Conducting a codesign focus group workshop to gather feedback that was analyzed using a template approach; and 3) Incorporation of consumer feedback to refine the program for future piloting in PCS. Components of the finalized intervention were mapped onto the TDF domains.

RESULTS

Six PCS were involved in the codesign focus group workshop, providing feedback on program structure, the topics and its order, and rehabilitation activities. A manualized four-week online group cognitive rehabilitation program titled "Promoting Cognitive Wellbeing in Prostate Cancer Survivors (ProCog)" was developed. Four sessions of 2-hours' duration were designed exploring: cognitive/brain functions; the impact of cancer treatments and ageing; the relationship between thoughts, feelings and behaviors; values-based goal-setting; and skills/strategies to manage fatigue and improve attention, memory, aspects of executive functioning, and emotional functioning.

CONCLUSIONS

Consumer input and guidance from the TDF ensures a robust development process for the online ProCog intervention, designed for and with PCS experiencing cognitive difficulties. As an important initial step before piloting, this adaptation and development process ensures that ProCog addresses consumer needs and preferences and targets factors increasing behavior change.

IMPLICATIONS FOR NURSING PRACTICE

This research raises awareness of possible cancer-related cognitive impairments in prostate cancer survivors and strategies for rehabilitation. ProCog is an accessible online intervention that nurses can use to refer patients needing cognitive rehabilitation.

Effects of Mobile Application-Based Cognitive Behavioral Therapy on Psychological Outcomes in Women Treated for Breast Cancer: A Randomized Controlled Pilot Trial in Germany

OBJECTIVE

Breast cancer has a strong impact on the mental state of those affected. Cognitive behavioral therapy (CBT) is one effective approach to reduce disease burden. This randomized controlled pilot trial aimed to assess the effect of the digital CBT-based application Living Well on psychological outcomes in a German female breast cancer population.

METHODS

Female breast cancer patients (n = 70) with ongoing or finished oncological treatment that is who were receiving or had received any type of oncological treatment were included in the study and randomized to an intervention group (IG, n = 32) receiving Living Well in addition to care as usual, and a control group (CG, n = 38) receiving care as usual only. Participants completed standardized questionnaires at baseline and after 2, 4, 8, and 12 weeks to assess anxiety and depression (HADS) as primary outcomes, distress (DT), health-related quality of life (HRQoL, AQoL-8D), and illness perception (B-IPQ) as secondary outcomes.

RESULTS

After 12 weeks, significant (p < 0.05) higher improvements in the IG could be observed in anxiety levels, HRQoL, and illness perception, when compared to the CG. Age and time since diagnosis were found to be relevant covariates for anxiety levels. In distress levels, the IG showed a clinically relevant and nearly significant reduction compared to the CG (p = 0.057). No effects could be observed in depression levels.

CONCLUSIONS

The results demonstrate the potential of Living Well to improve psychological outcomes of female breast cancer patients and encourage further studies evaluating the effectiveness of the digital application.

TRIAL REGISTRATION

The trial has been registered in the German Clinical Trials Register (DRKS00029918).

Computerized cognitive training improves cognitive function in primary breast cancer survivors

Cancer-related cognitive impairment has a significant impact on the quality of life and perceived cognitive ability of breast cancer patients and frequently affects attention, working memory, and executive function. Several interventional approaches to treat these deficits have been studied, including web-based cognitive training, but methods and timing in relation to cancer treatment are heterogeneous. Only few interventions start early after primary breast cancer treatment, a time when many patients report the greatest impairments in quality of life and cognition. In this randomized controlled pilot study, 31 breast cancer survivors with subjective cognitive deficits and a mean post-treatment duration of 6.6 months (SD = 9.3) were assigned to either 14 weeks of a web-based cognitive training program (training group, n = 16) or a control group (n = 15). All patients underwent detailed neuropsychological assessment, evaluation of patient-reported outcomes (PROMs), and neurological examination before (baseline, T1) and after (follow-up, T2) the intervention. Longitudinal (T1 vs. T2) and cross-sectional (T2) cognitive performance was assessed for both groups. Overall cognitive impairment significantly improved in the training group following training (56% vs 25%; p = 0.03, Phi = 0.51), but not in the control group (73% vs. 73%; p = 1) in the longitudinal analysis (T1 vs. T2). Specifically, the training group showed statistically significant improvement of executive functions (p = 0.004, Phi = 0.32). No effects of training on subjective cognitive deficits or PROMs were observed. Comparing cross-sectional cognitive performance at follow-up (T2), the training group showed a significantly lower rate of cognitive impairment overall (p = 0.007, Phi = 0.48) and a better cognitive performance for executive function (p = 0.04, Phi = 0.32) compared to the control group. In this prospective pilot study, web-based cognitive training was efficacious in improving overall cognitive performance and executive function. Importantly, this study investigated a web-based cognitive training for the immediate post-treatment phase, when up to 75% of breast cancer patients experience cognitive decline. These results indicate that cognitive training may improve neuropsychological outcomes for patients with breast cancer.

Comparative Effects of Exercise Interventions and Mindfulness-Based Interventions for Cognitive Impairment and Quality of Life in Breast Cancer Survivors During or After Cancer Treatment: A Systematic Review and Bayesian Network Meta-analysis

OBJECTIVE

The aim of this network meta-analysis was to compare the improvement effects of various exercise interventions and mindfulness-based interventions to determine the best interventions for the improvement of cognitive impairment.

DESIGN

Seven databases were searched to screen randomized controlled trials of exercise interventions and mindfulness-based interventions to improve cognitive impairment. The network meta-analysis was performed using Revman 5.3, R 4.2.1 and ADDIS 1.16.8 software.

RESULTS

Thirty-four randomized controlled trials involving 14 interventions were included in the study. In terms of cognitive function, except for mindfulness-based stress reduction, all interventions showed significantly greater improvement in cognitive function compared with conventional therapy. Physical activity and Qigong showed better effect in improving executive function. In terms of improving verbal memory, compensatory cognitive training, neurofeedback training, Qigong, and sham Qigong were more effective than other interventions. On performing surface under the cumulative ranking curve analysis, acceptance and commitment therapy, neurofeedback training, Qigong, and mediation had the best effects on cognitive function, quality of life, executive function, and processing speed, respectively.

CONCLUSIONS

Mindfulness-based interventions were found to be more effective than exercise interventions for alleviating cognitive impairment. More robust randomized controlled trials focusing on acceptance and commitment therapy for cognitive impairment are required to support the current evidence.

Web-based cognitive rehabilitation intervention for cancer-related cognitive impairment following chemotherapy for aggressive lymphoma: protocol for a randomised pilot trial

INTRODUCTION

Cancer-related cognitive impairment is common among people diagnosed with and treated for cancer. This can be a distressing and disabling side effect for impacted individuals. Interventions to mitigate cognitive dysfunction are available, but, to date, most have been trialled in samples that are largely or exclusively composed of people with solid tumours. Intervention strategies to support cognitive functioning are needed, but there is a paucity of research in this area. The main aim of this study is to test the feasibility and acceptability of methods and procedures intended for use in a definitive trial of a web-based cognitive rehabilitation programme, Responding to Cognitive Concerns (eReCog), in people who have received chemotherapy for aggressive lymphoma.

METHODS AND ANALYSIS

The proposed study is a single-site, parallel-group, pilot randomised controlled trial, with one baseline and one follow-up (or postintervention) assessment. 38 people from the target population with low perceived cognitive function based on the Cognitive Change Screen will be recruited from a specialist cancer centre between July 2023 and June 2024. After baseline assessment, participants will be randomised one-to-one to receive usual care only (a factsheet about changes in memory and thinking for people with cancer) or eReCog plus usual care. The 4-week eReCog intervention consists of four online modules offering psychoeducation on cognitive impairment associated with cancer and its treatment, skills training for improving memory, and attention and relaxation training. Study outcomes will include the feasibility of recruitment and retention at follow-up assessment (primary outcomes), as well as adherence to, usability of and intrinsic motivation to engage with eReCog, and compliance with study measures. The potential efficacy of eReCog will also be evaluated.

ETHICS AND DISSEMINATION

Ethical approval was granted by the Peter MacCallum Cancer Centre Human Research Ethics Committee in Victoria, Australia (HREC/97384/PMCC). Study findings will be disseminated via peer-reviewed publications and conference presentations.

Psychosocial Factors Associated with Cognitive Function in Prostate Cancer Survivors on Hormonal Treatments: A Systematic Review

Hormonal treatments (HT) for prostate cancer (e.g., androgen deprivation therapy) yield clinical and survival benefits, yet adverse cognitive changes may be a side effect. Since psychosocial factors are largely modifiable, interventions targeting these factors may help mitigate these adverse cognitive effects. This systematic review aimed to identify a range of psychosocial factors associated with cognitive function in individuals with prostate cancer undergoing HT and to determine whether these factors mitigate or exacerbate this effect. Applying PRISMA guidelines, a comprehensive search of relevant databases conducted in September 2023 using terms related to prostate cancer, hormone therapy, and cognitive outcomes was undertaken. The search yielded 694 unique abstracts, with 11 studies included for analysis examining the relationship between cognitive function and the following psychosocial factors: psychological distress, fatigue, insomnia, and coping processes. Findings were mixed with only two studies reporting significant associations between cognitive performance with fatigue and depression. Three studies that included measures of perceived cognitive function identified associations with depression, anxiety, fatigue, insomnia, illness threat appraisals, and coping styles. However, no studies found evidence for an association between self-reported and objective measures of cognitive functioning. Evidence regarding the association of interpersonal factors is lacking. Moreover, whether these factors mitigate or exacerbate the effect of HT on cognitive function still needs to be determined. Overall, the research exploring the association between psychosocial factors and cognitive function in prostate cancer survivors undergoing HT is still in its infancy. Further research is required to optimize the implementation of neuropsychological interventions for prostate cancer survivors.

Cancer-Related Cognitive Dysfunction: A Narrative Review for Clinical Practice

BACKGROUND

Cancer-related cognitive dysfunction (CRCD) is a major functional disorder in patients with cancer. This central nervous dysfunction is found in up to 60% of patients after tumour therapy, often significantly limits the quality of life, and significantly impedes participation in working life. For this reason, diagnosis and treatment of CRCD are of central importance. This narrative review is intended to provide an overview and support for practical clinical care with regard to diagnostics and therapeutic options.

SUMMARY

In Germany, CRCD has received insufficient attention in clinical practice due to the lack of guidelines for diagnosis and therapy. The pathophysiology is complex and cannot be explained by chemotherapeutic treatment alone. In addition to the tumour disease as such and the tumour therapy, psychological factors such as anxiety and depression as well as sleep disorders also play a significant role. Today, it is known that in addition to age, molecular genetic changes also have an effect on cognitive function. Morphologically, CRCD can be located in the frontal cortex and hippocampus. In addition to easy-to-use screening instruments such as the visual analogue scale, validated questionnaires such as the Questionnaire of Subjectively Experienced Deficits in Attention (FEDA) developed in Germany are also available. These allow the suspected diagnosis to be substantiated and the patient to be referred to further neurological, neuropsychological, or psycho-oncological diagnostics. Within the framework of further neuropsychological diagnostics, the International Cognition and Cancer Task Force (ICCTF) recommends testing learning, memory, processing speed, and executive functions. From the authors' point of view, a step-by-step diagnosis is recommended in order to avoid overdiagnosis. In clinical practice, graduation according to the "Common Terminology Criteria for Adversity Events" (CTCAE Version 5.0) is suitable for assessing the degree of severity. Cognitive training should be behaviourally oriented and include regular practice of cognitive skills to restore attention, psychomotor speed, memory, and executive functions. The best evidence is currently found for web-based training programmes that can be used by the patient at home. There is also evidence for mindfulness training and physical exercises. In particular, the combination of these three therapeutic elements currently seems to be the optimal treatment strategy for CRCD.

KEY MESSAGES

Cognitive dysfunction should be given much more attention in the clinical care of cancer patients. Diagnostic tools for this purpose and evidence-based therapeutic interventions are available. In the future, networks should be created that allow for better care of patients with CRCD.

Web-based psychoeducational interventions for managing cognitive impairment-a systematic review

Objective

Web-based rehabilitation, a branch of telerehabilitation, is carried out over the internet, unrestricted by time or place. Even though web-based interventions have been reported as feasible and effective in cases of mood disorders, for example, such evidence on the effectiveness of web-based cognitive rehabilitation remains unclear. This systematic review summarizes current knowledge on web-based psychoeducational programs aiming to manage cognitive deficits in patients with diseases that affect cognition.

Methods

Using the Ovid database and the Web of Science, we systematically searched the Cochrane Database of Systematic Reviews, Medline, and PsycINFO to identify eligible studies. The review protocol (CRD42021257315) was pre-registered with the PROSPERO International Prospective Register of Systematic Reviews. The search was performed 10/13/2022. Two reviewers independently screened titles, abstracts, and full-texts, and extracted data for the selected studies. Two independent reviewers assessed the methodological quality.

Results

The search retrieved 6,487 articles. Four studies with different patient groups (stroke, traumatic brain injury, brain tumor, and cancer) met the inclusion criteria of this systematic review. The studies examined systematic cognition-focused psychoeducational rehabilitation programs in which the patient worked independently. Three studies found positive effects on subjective cognitive functions, executive functions, and self-reported memory. No effects were found on objective cognitive functions. However, the studies had methodological weaknesses (non-randomized designs, small sample sizes, vaguely described interventions). Overall, adherence and patient satisfaction were good/excellent.

Conclusion

Web-based cognitive intervention programs are a new approach to rehabilitation and patient education. The evidence, although scarce, shows that web-based interventions are feasible and support subjective cognitive functioning. However, the literature to date is extremely limited and the quality of the studies is weak. More research with high-quality study designs is needed.

Digital Health Interventions for Adult Patients With Cancer Evaluated in Randomized Controlled Trials: Scoping Review

BACKGROUND

Digital care has become an essential component of health care. Interventions for patients with cancer need to be effective and safe, and digital health interventions must adhere to the same requirements.

OBJECTIVE

The purpose of this study was to identify currently available digital health interventions developed and evaluated in randomized controlled trials (RCTs) targeting adult patients with cancer.

METHODS

A scoping review using the JBI methodology was conducted. The participants were adult patients with cancer, and the concept was digital health interventions. The context was open, and sources were limited to RCT effectiveness studies. The PubMed, CINAHL, Embase, Cochrane Library, Research Information Sharing Service, and KoreaMed databases were searched. Data were extracted and analyzed to achieve summarized results about the participants, types, functions, and outcomes of digital health interventions.

RESULTS

A total of 231 studies were reviewed. Digital health interventions were used mostly at home (187/231, 81%), and the web-based intervention was the most frequently used intervention modality (116/231, 50.2%). Interventions consisting of multiple functional components were most frequently identified (69/231, 29.9%), followed by those with the self-manage function (67/231, 29%). Web-based interventions targeting symptoms with the self-manage and multiple functions and web-based interventions to treat cognitive function and fear of cancer recurrence consistently achieved positive outcomes. More studies supported the positive effects of web-based interventions to inform decision-making and knowledge. The effectiveness of digital health interventions targeting anxiety, depression, distress, fatigue, health-related quality of life or quality of life, pain, physical activity, and sleep was subject to their type and function. A relatively small number of digital health interventions specifically targeted older adults (6/231, 2.6%) or patients with advanced or metastatic cancer (22/231, 9.5%).

CONCLUSIONS

This scoping review summarized digital health interventions developed and evaluated in RCTs involving adult patients with cancer. Systematic reviews of the identified digital interventions are strongly recommended to integrate digital health interventions into clinical practice. The identified gaps in digital health interventions for cancer care need to be reflected in future digital health research.

Systematic Review of Functional Outcomes in Cancer Rehabilitation

OBJECTIVE

To systematically review the evidence regarding rehabilitation interventions targeting optimal physical or cognitive function in adults with a history of cancer and describe the breadth of evidence as well as strengths and limitations across a range of functional domains.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Plus, Scopus, Web of Science, and Embase. The time scope was January 2008 to April 2019.

STUDY SELECTION

Prospective, controlled trials including single- and multiarm cohorts investigating rehabilitative interventions for cancer survivors at any point in the continuum of care were included, if studies included a primary functional outcome measure. Secondary data analyses and pilot/feasibility studies were excluded. Full-text review identified 362 studies for inclusion.

DATA EXTRACTION

Extraction was performed by coauthor teams and quality and bias assessed using the American Academy of Neurology (AAN) Classification of Evidence Scheme (class I-IV).

DATA SYNTHESIS

Studies for which the functional primary endpoint achieved significance were categorized into 9 functional areas foundational to cancer rehabilitation: (1) quality of life (109 studies), (2) activities of daily living (61 studies), (3) fatigue (59 studies), (4) functional mobility (55 studies), (5) exercise behavior (37 studies), (6) cognition (20 studies), (7) communication (10 studies), (8) sexual function (6 studies), and (9) return to work (5 studies). Most studies were categorized as class III in quality/bias. Averaging results found within each of the functional domains, 71% of studies reported statistically significant results after cancer rehabilitation intervention(s) for at least 1 functional outcome.

CONCLUSIONS

These findings provide evidence supporting the efficacy of rehabilitative interventions for individuals with a cancer history. The findings should be balanced with the understanding that many studies had moderate risk of bias and/or limitations in study quality by AAN criteria. These results may provide a foundation for future work to establish clinical practice guidelines for rehabilitative interventions across cancer disease types.

Effective non-pharmacological interventions for cancer related cognitive impairment in adults (excluding central nervous system or head and neck cancer): systematic review and meta-analysis

INTRODUCTION

Cancer-related cognitive impairment (CRCI) is prevalent in cancer survivors, and impairments affect daily living tasks and overall wellbeing. This review aimed to identify and evaluate published randomized controlled trials (RCTs) of interventions to manage CRCI in adult populations, to analyze their effectiveness and to investigate the quality of the studies.

EVIDENCE ACQUISITION

Seven databases were searched (Medline, Scopus, CINAHL, AMED, PsychINFO, OTseeker, and the Cochrane Database of Systematic Reviews), including years 2005-2020, for randomized controlled trials (RCTs) investigating interventions to address cognition for adults with cancer. The final search was conducted in February 2021. The quality of studies was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for RCTs. Meta-analysis used comprehensive meta-analysis software. The study protocol was registered with PROSPERO (registration N. CRD42017076868).

EVIDENCE SYNTHESIS

A total of 45 studies involving 4727 participants examined interventions for CRCI and met selection criteria. Categories of interventions included cognitive training-based intervention (N.=15), cognitive behavior therapy (CBT) (N.=4), physical activity (N.=16) and other supportive therapies (N.=10). Meta-analysis indicated beneficial overall effects for all categories of interventions: cognitive training (standardized mean difference [SMD]=0.41, 95% CI: 0.28-0.53, I2=88.87%); CBT (SMD=0.30, 95% CI: 0.14-0.46, I2=44.86%); physical activity (SMD=0.27, 95% CI: 0.20-0.35, I2=37.67%); and supportive therapies (SMD=0.27, 95% CI: 0.16-0.39, I2=64.94%). Studies used self-report cognitive outcome measures and neurocognitive testing, or a mixture.

CONCLUSIONS

Findings suggest that effective intervention for CRCI exist, and cognitive training is consistently supported as an effective intervention; however, a high level of heterogeneity was found. CRCI research is currently dominated by breast cancer survivors, and quality research is also needed to address the broader population of cancer survivors who experience CRCI.

Management of Cancer-Related Cognitive Impairment: A Systematic Review of Computerized Cognitive Stimulation and Computerized Physical Activity

Cancer-related cognitive impairment (CRCI) occurs frequently in patients living with cancer, with consequences on quality of life. Recently, research on the management of these difficulties has focused on computerized cognitive stimulation and computerized physical activity programs. This systematic review presents the state of knowledge about interventions based on computerized-cognitive stimulation and/or physical activity to reduce CRCI. The review followed the PRISMA guidelines. A search was conducted in PUBMED and Web of Science databases. Risk of bias analysis was conducted using the Rob2 tool and the quality of evidence was conducted following the GRADE approach. A total of 3776 articles were initially identified and 20 of them met the inclusion criteria. Among them, sixteen investigated computerized-cognitive stimulation and four computerized-physical activity. Most of the studies were randomized controlled trials and assessed the efficacy of a home-based intervention on objective cognition in adults with cancer. Overall, cognitive improvement was found in 11/16 computerized-cognitive stimulation studies and 2/4 computerized-physical activity studies. Cognitive stimulation or physical activity improved especially cognitive complaints, memory, and attention. These results suggest the efficacy of both computerized-cognitive stimulation and physical activity. However, we report a high risk of bias for the majority of studies and a low level of quality of evidence. Therefore, further investigations are needed to confirm the efficacy of these interventions and to investigate the possible added benefit on cognition of a combined computerized-cognitive/physical intervention.

Barriers and facilitators to the availability of efficacious self-directed digital health tools for adults living with cancer and their caregivers: A systematic literature review and author survey study

OBJECTIVE

This study aimed to examine barriers and facilitators to the dissemination of efficacious self-directed digital health tools for adults affected by cancer, and quantify funding used to develop and evaluate these digital health tools.

METHODS

We conducted: (1) a systematic literature review to identify efficacious self-directed digital health tools for adults affected by cancer, published between 2009 and 2019 and (2) an author survey to identify barriers and facilitators to dissemination of those tools, grant funding and the user centredness of their design (UCD) process.

RESULTS

Of 1314 screened articles, 29 articles describing 26 tools met the inclusion criteria. From 26 surveys sent, 12 were completed, 6 of which described disseminated tools. Whilst researchers' motivation and infrastructure support facilitate tool dissemination, limited funds, lack of infrastructure and limited research timelines are the most common barriers. A median of AUD$250,000 was spent on tools not disseminated to end-users.

CONCLUSION

Although incorporating UCD processes in the development of digital health tools is important, it is imperative to integrate implementation processes into the planning stages of tool development to ensure dissemination.

PRACTICE IMPLICATIONS

Researchers, academic institutions, funding agencies and government and non-government organisations all have roles to play to support long-term implementation.

The effects of neuroplasticity-based auditory information processing remediation in adults with chronic traumatic brain injury

BACKGROUND

Adults with chronic traumatic brain injury (TBI) may experience long-term deficits in multiple cognitive domains. Higher-order functions, such as verbal memory, are impacted by deficits in the ability to acquire verbal information.

OBJECTIVE

This study investigated the effects of a neuroplasticity-based computerized cognitive remediation program for auditory information processing in adults with a chronic TBI.

METHODS

Forty-eight adults with TBI were randomly assigned to an intervention or control group. Both groups underwent a neuropsychological assessment at baseline and post-training. The Intervention group received 40 one-hour cognitive training sessions with the Brain Fitness Program.

RESULTS

The intervention group improved in performance on measures of the Woodcock-Johnson-III Understanding Directions subtest and Trail Making Test Part-A. They also reported improvement on the cognitive domain of the Cognitive Self-Report Questionnaire.

CONCLUSIONS

The present study demonstrated that a neuroplasticity-based computerized cognitive remediation program may improve objective and subjective cognitive function in adults with TBI several years post-injury.

Cognitive changes after breast cancer: a scoping review to identify problems encountered by women when returning to work

PURPOSE

A scoping review of international literature was conducted to identify the various problems encountered by women with breast cancer associated with cognitive deficits, and the relationship to work roles and tasks.

METHOD

This scoping review was conducted using the structure recommended by Arksey & O'Malley in consideration of the PRISMA extension for Scoping Reviews checklist and reviewed for quality, inclusion criteria and key findings related to cognitive changes after breast and impact on work. Searches were conducted in five databases from January 2000 to December 2020.

RESULTS

A total of 34 studies met the inclusion criteria. There were 20 quantitative studies, 11 qualitative studies, one mixed method and two case study reports. Findings related to the type of cognitive changes that impact work performance and participation, how these are measured in a work context and the types of interventions directed towards improving cognitive function at work after breast cancer. An absence of ecologically valid assessments and interventions with a coherent approach to early identification and management of cognitive changes after breast cancer was apparent.

CONCLUSION

Breast cancer survivors can experience challenges in their employment due to cognitive deficits, which may lead to the loss of their employment. Health professionals need to explore breast cancer survivors work role and consider appropriate referrals to ensure women receive the necessary support and rehabilitation to address cognitive problems impacting work performance. Further research is needed to develop workplace-based cognitive assessments and interventions to improve the work performance and participation of women with breast cancer experiencing cognitive deficits.Implications for RehabilitationWork participation can be negatively impacted by unacknowledged cognitive changes that are not assessed and managed throughout the cancer survivorship journey.Health professionals in health care systems, particularly occupational therapists need to consider appropriate referrals to workplace rehabilitation providers to ensure necessary support and rehabilitation to address cognitive problems impacting on work performance.Occupational therapists performing workplace assessments for women with breast cancer, should assesses cognitive function in accordance with the cognitive demands of the job and work environment, and involve the employer and client in workplace based cognitive interventions.

Measuring Self-Reported Cancer-Related Cognitive Impairment: Recommendations From the Cancer Neuroscience Initiative Working Group

Cancer and its treatments are associated with increased risk for cancer-related cognitive impairment (CRCI). Methods and measures used to study and assess self-reported CRCI (sr-CRCI), however, remain diverse, resulting in heterogeneity across studies. The Patient-Reported Outcomes Working Group has been formed to promote homogeneity in the methods used to study sr-CRCI. In this report, using a psychometric taxonomy, we inventory and appraise instruments used in research to measure sr-CRCI, and we consider advances in patient-reported outcome methodology. Given its psychometric properties, we recommend the Patient-Reported Outcome Measurement Information System Cognitive Function Short Form 8a for measurement of sr-CRCI in cancer patients and survivors, at a minimum, to increase scientific rigor and progress in addressing CRCI.

Online couple interventions in cancer

PURPOSE OF REVIEW

Cancer diagnosis and treatment can have long-lasting psychological and physical consequences that affect both patients and their intimate partners. Improved understanding of extant dyadic interventions in the context of cancer, and how access to these may be enhanced through web-based technologies, introduce new directions for how cancer-related psychological distress for couples may be ameliorated.

RECENT FINDINGS

Couples are negatively impacted by cancer, both individually, and as a dyad. Bolstering techniques to support effective communication about common cancer-related concerns and support for adjusting to new roles and responsibilities may help to strengthen the couple's relationship so partners are better able to cope with cancer. Although there are various intervention options available for couples dealing with cancer, many pose barriers to participation because of constraints on time and/or distance. However, online interventions have been shown to be effective, both in easing psychological distress and reducing participant burden.

SUMMARY

Couples dealing with cancer experience psychological distress and must learn to navigate changing roles and responsibilities in the face of the disease. Online interventions offer flexible and innovative platforms and programs that help to address couples' educational needs while strengthening dyadic coping.

Online interventions aimed at reducing psychological distress in cancer patients: evidence update and suggestions for future directions

PURPOSE OF REVIEW

A great proportion of people affected by cancer experience psychological distress. To reduce pressure on limited health-management resources available, evidence-based eHealth or online interventions can fill an important gap by making psychosocial care more easily accessible. However, evidence of their effectiveness is mixed. This present review provides an update on the effectiveness of online interventions in reducing psychological distress in patients with cancer by including studies published from January 2018 to September 2019.

RECENT FINDINGS

Thirty-three publications describing online interventions were included in the review, including web-based, blended care, telehealth, mHealth, and other online interventions. There was great heterogeneity across studies. The evidence of online interventions' effectiveness in reducing distress was mixed; there was partial support for reduction in psychological distress and depression, but limited evidence for reducing anxiety. Some important limitations should be taken into account when interpreting the results.

SUMMARY

Online interventions for people affected by cancer, in general, are well received and seem to be a necessary component of comprehensive cancer care. However, these interventions should be more rigorously tested to provide more conclusive evidence about their effectiveness.

Cognitive rehabilitation program to improve cognition of cancer patients treated with chemotherapy: A 3-arm randomized trial

Background

There is no treatment for cancer‐related cognitive impairment, an important adverse effect that negatively impacts quality of life (QOL). We conducted a 3‐arm randomized controlled trial to evaluate the impact of computer‐assisted cognitive rehabilitation (CR) on cognition, QOL, anxiety, and depression among cancer patients treated with chemotherapy.

Methods

Patients who reported cognitive complaints during or after completing chemotherapy were randomly assigned to 1 of 3 12‐week CR programs: computer‐assisted CR with a neuropsychologist (experimental group A), home cognitive self‐exercises (active control group B), or phone follow‐up (active control group C). Subjective cognition was assessed by the Functional Assessment of Cancer Therapy–Cognitive Function (FACT‐Cog), objective cognition was assessed by neuropsychological tests, QOL was assessed by the FACT‐General, and depression and anxiety were assessed by psychological tests. The primary endpoint was the proportion of patients with a 7‐point improvement in the FACT‐Cog perceived cognitive impairment (PCI) score.

Results

Among the 167 enrolled patients (median age, 51 years), group A had the highest proportion of patients with a 7‐point PCI improvement (75%), followed by groups B (59%) and C (57%), but the difference was not statistically significant (P = .13). Compared with groups B and C, the mean difference in PCI score was significantly higher in group A (P = .02), with better perceived cognitive abilities (P < .01) and a significant improvement in working memory (P = .03). Group A reported higher QOL related to cognition (FACT‐Cog QOL) (P = .01) and improvement in depression symptoms (P = .03).

Conclusions

These results suggest a benefit of a computer‐based CR program in the management of cancer‐related cognitive impairment and complaints.

In this 3‐arm randomized clinical trial of 167 patients, computer‐assisted cognitive rehabilitation improved cognitive complaints, with significant improvement in working memory, quality of life related to cognition, and depression symptoms. Computer‐assisted cognitive rehabilitation is a compelling approach toward the management of cancer‐related cognitive impairment and complaints.

Internet-based cognitive rehabilitation for WORking Cancer survivors (i-WORC): study protocol of a randomized controlled trial

Background

Cognitive problems are common in non-central nervous system cancer survivors. These problems are perceived as an important contributor to decline in work performance and work ability. Various interventions for cognitive problems have been proposed, but effectiveness regarding work-related outcomes has not yet been established. Effective treatment options to alleviate the adverse influence of cognitive problems on work performance are needed for working cancer survivors. In this paper, we will describe the design of a randomized, controlled, multicenter trial that evaluates the (cost-)effectiveness of an Internet-based cognitive rehabilitation program for occupationally active cancer survivors confronted with cognitive problems.

Methods/ design

A three-armed randomized controlled trial will be conducted, including two intervention groups (i.e., basic and extensive cognitive rehabilitation program) and one waitlist control group. In total, 261 cancer survivors (18–65 years) who have returned to work and who experience cognitive problems will be recruited. Patients with and without cognitive impairment as established in a neuropsychological assessment will be eligible; stratification will take place based on the presence of this cognitive impairment. The extensive intervention arm will contain a comprehensive training program (including psycho-education, fatigue management, and cognitive strategy training) with individual guidance (blended intervention). The basic intervention arm will contain a brief cognitive training program (including psycho-education and fatigue management) without individual guidance. The primary outcome will be accomplishment of an individually defined work-related treatment goal. Secondary outcomes include, among others, subjective cognitive functioning, work functioning, and quality of life. Primary and secondary outcomes will be measured at baseline (T0) and at 12 weeks (T1) and 26 weeks (T2) post-randomization.

Discussion

About 40–50% of the cancer patients worldwide are of working age at time of diagnosis. Many of the occupationally active cancer survivors experience cognitive problems. Both from an individual and a societal perspective, it is important to sustain cancer survivors’ employability. An effective treatment to alleviate the impact of cognitive decline and to improve work ability might help cancer survivors to sustain employability.

Online psychosocial interventions for posttreatment cancer survivors: an international evidence review and update

PURPOSE OF REVIEW

The present review describes recent research on online psychosocial interventions for posttreatment cancer survivors from January 2018 to June 2019.

RECENT FINDINGS

Twenty-three studies were included in the review (the majority included were feasibility studies and only five randomized controlled trials had large samples). Websites were the most common platforms for intervention delivery (9/23) and cognitive behavioral therapy was the most frequently used therapeutic approach (11/23). Three interventions based on this framework and delivered via websites or combined website-telehealth platforms showed to be effective in improving psychosocial issues (fear of cancer recurrence, insomnia, sleep quality, and prospective memory failures) in posttreatment cancer survivors. Web-based self-compassion writing was also found to be effective in addressing body image distress and body appreciation in breast cancer survivors. Feasibility studies mostly showed online interventions to be plausible and acceptable to cancer survivors. A good representation of online interventions for young adult cancer survivors (30%) was found.

SUMMARY

Online interventions show promise in addressing the psychosocial needs of cancer survivors. Despite new online interventions being found to be feasible and acceptable and some showing promise in addressing important psychosocial issues in cancer survivors posttreatment, more rigorous studies are required to inform supportive care for this population.

Long-Term Fatigue and Cognitive Disorders in Breast Cancer Survivors

Survivors of early-stage breast cancer may report treatment-related side effects that persist for several years after the end of primary treatment. Among these, fatigue and cognitive disorders are frequent complaints and can negatively impact quality of life. Cancer-related fatigue is a very prevalent and distressing long-term side effect among breast cancer survivors that typically improves after completion of treatment, although many patients report severe fatigue several years post-treatment. Cognitive disorders are also common among survivors of breast cancer, especially if treated with chemotherapy. These symptoms are usually mild-to-moderate and often transient. Cognitive recovery is frequently observed within months or a few years after completion of chemotherapy or endocrine therapy. However, some breast cancer survivors may have persistent cognitive difficulties. Several types of interventions have proved to be beneficial in reducing cancer-related fatigue and cognitive difficulties. Most of these interventions for cancer-related fatigue are thought to be effective by reducing inflammation or disrupting pro-inflammatory circuits. Further studies are needed on cognitive management that has showed promising results. This narrative review summarizes the state of the art regarding long-term fatigue and cognitive disorders in patients with early breast cancer, describing prevalence, impact, pathophysiology, and risk factors, and focusing on available interventions.

Computerized programs for cancer survivors with cognitive problems: a systematic review

PURPOSE

This study aimed to review and identify characteristics and lessons learned from studies on computerized cognitive interventions for cancer survivors (CSs) with cognitive dysfunction, exploring the content and results of interventions.

METHODS

Studies were collected from the CINAHL, Web of Science, PubMed, and PsycINFO databases.

RESULTS

Seven articles that met the inclusion criteria were included. Reviewed studies measured objective cognitive function, subjective cognitive function, and psychological aspects. Computerized interventions for CSs with cognitive decline were effective for executive function, memory, working memory, and speed of thought in the domain of objective cognitive function. Some subjective cognitive functions also showed significant improvement.

CONCLUSIONS

Computerized cognitive interventions have a positive impact on objective, subjective, and psychological aspects of cognitive problems. Further research needs to include more men as well as different cancer types. Programs also should include more than one target domain. Future researchers need to develop mobile applications that can effectively use computerized cognitive interventions.

IMPLICATIONS FOR CANCER SURVIVORS

Results of this study should help provide optimal approaches to develop and apply effective computerized-cognitive-intervention programs. Health care providers need to be involved in these types of interventions and methods to encourage CSs to proactively practice cognitive-function training need to be developed.

Adaptations to cognitive problems reported by breast cancer survivors seeking cognitive rehabilitation: A qualitative study

OBJECTIVE

Qualitative studies have elucidated cancer survivors' experiences of cognitive changes associated with cancer and cancer treatment. This study specifically explored experiences of women treated for breast cancer who were seeking cognitive rehabilitation. The objective was to characterise the frequency and nature of cognitive changes and adaptations to cognitive change reported by these participants to better understand treatment needs of this group.

METHOD

Australian women who had completed primary treatments for breast cancer (surgery, chemotherapy, and/or radiotherapy) and volunteered to participate in one of two cognitive rehabilitation intervention studies were interviewed via telephone. Interview responses regarding cognitive changes and adaptations to cognitive change were transcribed by the interviewers, then coded and analysed by two researchers using content analysis.

RESULTS

Among the 95 participants (age M=54.3 years, SD=9.6), the most commonly reported cognitive change was memory (79% of participants) and 61% reported more than one type of cognitive change. Adaptations to change were reported by 87% of participants, with written or electronic cues the most common (51%). Most often, participants reported using a single type of adaptation (48%) with only 39% reporting multiple types of adaptations.

CONCLUSIONS

Women treated for breast cancer, who were seeking cognitive rehabilitation, most commonly reported memory changes, which were mainly managed through a single type of adaptation. These results suggest that there is considerable scope for increasing the range of cognitive adaptations to improve the quality of life of cancer survivors who experience adverse cognitive changes.

The implementation of web-based cognitive rehabilitation in adult cancer survivors: examining participant engagement, attrition and treatment fidelity

PURPOSE

Low engagement and high attrition are common challenges in web-based interventions. Typical measures of engagement reported in the literature are not meaningful for describing participant activity within the intervention and can be misleading. This research aimed to develop a more meaningful method of measuring engagement in an online cognitive rehabilitation program whilst monitoring treatment fidelity.

METHODS

A pilot study and randomised controlled trial (RCT) were conducted. Data from 60 participants were analysed from three intervention groups: pilot cancer group, pilot non-cancer group and RCT cancer group. Groups completed the 4-week eReCog program comprised of four online modules. Engagement scores were calculated based on activities completed in each module. Attrition, interaction with the program facilitator and correlations with outcome measures were analysed.

RESULTS

Overall engagement in the intervention was high. The non-cancer group participated significantly less than the cancer groups (p = < 0.001), whereby the percentage of activity items completed was 92, 87 and 78% in the pilot cancer, RCT cancer and pilot non-cancer groups, respectively. Attrition was higher in the pilot non-cancer group (24%) compared to the pilot cancer group (8%) and the RCT cancer group (16%). Total engagement was correlated with fewer prospective memory problems on instrumental activities of daily living (p = 0.018).

CONCLUSIONS

Measuring completed activities in online interventions appears a more meaningful measure of engagement than other conventional methods described in the literature and has the potential to increase treatment fidelity in web-based research.
