Abstract
This article is the second part of a systematic review of evidence for the effectiveness of cancer rehabilitation interventions within the scope of occupational therapy that address the activity and participation needs of adult cancer survivors. This article focuses on the use of multidisciplinary rehabilitation and interventions that address psychosocial outcomes, sexuality, and return to work. Strong evidence indicates that multidisciplinary rehabilitation benefits cancer survivors and that psychosocial strategies can reduce anxiety and depression. Moderate evidence indicates that interventions can support survivors in returning to the level of sexuality desired and help with return to work. Part 1 of the review also appears in this issue.
Advances in treatment have improved survival rates in patients with cancer, including those who emerge from cancer treatment needing rehabilitation. Consequently, patients are living longer with the physical impairments that result from their disease and its treatment in addition to comorbidities they acquire as they age (American Cancer Society, 2015; Ries et al., 2002). As of January 2014, the United States had nearly 14.5 million cancer survivors (American Cancer Society, 2015). The number of survivors is projected to grow to 18 million by 2022 (Howlader et al., 2009). Cancer can now be categorized as a chronic condition for many people, resulting in a stronger focus on return to function, participation, and quality of life (Howlader et al., 2009).
The potential for cancer to result in disability can increase the cost and burden for cancer survivors, highlighting the importance of long-term health outcomes (Cohen, 2010; Extermann, 2007). Research has shown that functional measures are strong predictors of survival for older adults living in the community (Keeler, Guralnik, Tian, Wallace, & Reuben, 2010). Functional decline increases significantly among people with cancer age ≥65 yr, and older cancer survivors experience more functional decline than older adults without cancer (Lunney, Lynn, Foley, Lipson, & Guralnik, 2003; Sweeney et al., 2006). Cancer and its treatment can cause interruptions to daily routines, self-care, work, and leisure and social activities (Longpre & Newman, 2011).
Objective of the Systematic Review
The objective of this review was to systematically search for and assess the evidence supporting interventions within the scope of occupational therapy to improve occupational engagement. The focused question guiding selection of research studies for review was “What is the effectiveness of cancer rehabilitation interventions within the scope of occupational therapy practice to address the activity and participation needs of adult cancer survivors in activities of daily living (ADLs), instrumental activities of daily living, work, leisure, social participation, and rest and sleep?”
This systematic review was supported by the American Occupational Therapy Association (AOTA) as part of the Evidence-Based Practice (EBP) Project (Lieberman & Scheer, 2002). Because of the breadth of the systematic review, the results were divided into two parts. This article presents Part 2 of the systematic review, which is focused on the benefits of multidisciplinary rehabilitation and interventions that address psychosocial outcomes, sexuality, and return to work.
Method
Process
Search terms for the reviews were developed by the methodology consultant to the AOTA EBP Project and AOTA staff, along with the review authors and the advisory group. The search terms were related to population (adult cancer survivors), types of intervention, outcomes, sequelae, and types of study design to be included in the systematic review. Databases and sites searched included Medline, PsycINFO, CINAHL, and OTseeker. In addition, consolidated information sources, such as the Cochrane Database of Systematic Reviews, were included in the search.
Eligibility Criteria
Included in the review were peer-reviewed scientific articles on adults with cancer published in English between 1995 and 2014 and within the scope of practice of occupational therapy. The review excluded data from presentations, conference proceedings, non–peer-reviewed research literature, dissertations, and theses. The review also excluded studies focusing on caregivers, family members, or friends rather than cancer survivors; studies of childhood cancer; and interventions that required an academic degree other than occupational therapy (e.g., music therapy). AOTA uses standards of evidence modeled on those developed in evidence-based medicine (Sackett, Rosenberg, Gray, Haynes, & Richardson, 1996):
Level I: Systematic reviews, meta-analyses, randomized controlled trials (RCTs)
Level II: Two-group, nonrandomized studies (e.g., cohort, case control)
Level III: One-group, nonrandomized studies (e.g., pretest and posttest)
Level IV: Descriptive studies that include analysis of outcomes (e.g., single-subject design, case series)
Level V: Case reports and expert opinion that include narrative literature reviews and consensus statements.
Studies included in the review provide Level I, II, and III evidence. Level IV evidence was included only when higher level evidence on a given topic was not found; no Level V evidence was included in this part of the review.
Data Extraction
A team of three reviewers (Hunter, Gibson, and D’Amico) worked together to evaluate all articles at all stages of the review. The synthesis entailed a detailed reading of the studies and the completion of the evidence table describing each study specifically. Figure 1 in Part 1 of the review depicts the flow of abstracts and articles through the process (Hunter, Gibson, Arbesman, & D’Amico, 2017; see https://doi.org/10.5014/ajot.2017.023564). The evidence table for Part 2 is provided in Supplemental Table 1 (available online at http://otjournal.net; navigate to this article, and click on “Supplemental”). The articles were grouped into themes and analyzed and reported by theme.
Analysis
Analysis of study design, outcomes, and risk of bias determined which studies were assessed as strong or moderate evidence. Strong evidence typically includes two or more well-designed RCTs. Moderate evidence includes one RCT, two or more studies providing lower level evidence, or inconsistent findings from well-designed projects. Only selected articles from the systematic review are mentioned in this article.
Results
The review team identified a total of 138 articles for inclusion in the final qualitative synthesis; 52 articles are described in this article (Part 2). Forty-five articles provide Level I evidence, 3 provide Level II evidence, 3 provide Level III evidence, and 1 provides Level IV evidence. Articles were organized into four broad intervention areas: multidisciplinary rehabilitation (18 articles), psychosocial outcomes (29 articles), sexuality (2 articles), and return to work (3 articles).
Risk of Bias
Risk of bias was assessed using the Cochrane risk-of-bias guidelines described by Higgins, Altman, and Sterne (2011; see Supplemental Table 2, online). The method for assessing the risk of bias of systematic reviews was based on the Assessment of Multiple Systematic Reviews system developed by Shea et al. (2007; see Supplemental Table 3, online).
Outcome Measures
Although many studies discussed ADLs, function, return to work, participation, and sleep as a goal, few if any measured these constructs. Instead, the measurement tools used addressed quality of life (e.g., SF–12, SF–36) and symptom control, which many authors indicated would allow return to previous activities. Other studies discussed these constructs generically in their findings as wellness, health, and quality of life. Most studies discussed the interventions provided, even occupation-based interventions, in terms of addressing mental or emotional health, physical activity, symptom management, and well-being. Only a few studies discussed occupation-based outcomes or outcome measures.
Interventions in Multidisciplinary Rehabilitation Programs
Multidisciplinary rehabilitation programs use a team approach that includes occupational therapy, physical therapy, and other allied health professions. Eighteen articles related to the use of multidisciplinary rehabilitation programs met the criteria and were included in the review; 2 were Level I systematic reviews, 12 were Level I RCTs, 2 were Level II studies, 1 was a Level III study, and 1 article provided Level IV evidence.
Strong Evidence.
Strong evidence indicates that rehabilitation programs benefit survivors with many types of cancer. Multidisciplinary rehabilitation programs resulted in improved function and participation regardless of type of cancer, stage of cancer, or age of survivor (Level I: Cinar et al., 2008; Khan, Amatya, Pallant, Rajapaksa, & Brand, 2012; Lapid et al., 2007; Scott et al., 2013; Level II: Gordon, Battistutta, Scuffham, Tweeddale, & Newman, 2005; Level III: Hanssens et al., 2011).
Moderate Evidence.
Moderate evidence indicates that rehabilitation can be beneficial both before and after treatment (Level I: Benzo et al., 2011). Cognitive rehabilitation improved attention and overall quality of life (Level I: Cherrier et al., 2013). Aquatic therapy and exercise were beneficial for breast cancer survivors (Level I: Cuesta-Vargas, Buchan, & Arroyo-Morales, 2014). Rehabilitation in advanced, progressive, recurrent cancer was found to be cost-effective and to increase quality of life (Level I: Jones, Fitzgerald, et al., 2013).
Psychosocial Interventions
Twenty-nine articles related to psychosocial interventions met the criteria for the review: 6 Level I systematic reviews, 21 Level I RCTs, 1 Level II, and 1 Level III studies. Such interventions included life review, stress management, expressive or disclosure groups, problem-solving therapy, mindfulness-based therapy, and cognitive–behavioral therapy.
Strong Evidence.
Strong evidence indicates that psychosocial strategies, including cognitive–behavioral and educational interventions (e.g., problem solving, knowledge of illness and side effects), reduce anxiety >3 mo posttreatment and depression 1–3 mo posttreatment (Level I: Chien, Liu, Chien, & Liu, 2014).
Moderate Evidence.
Moderate evidence supports a variety of psychosocial interventions. A systematic review found that psychosocial interventions increased quality of life for people with advanced-stage cancer (Level I: Uitterhoeve et al., 2004). Short-term life review increased spiritual well-being for people with terminal cancer (Level I: Ando, Morita, Akechi, & Okamoto, 2010), and stress management groups increased psychosocial adjustment among breast cancer survivors (Level I: Antoni et al., 2006).
Problem-solving therapy using home-based care training by phone helped women with breast cancer reduce stress (Level I: Allen et al., 2002), and cognitive–behavioral therapy decreased symptom limitations for people undergoing chemotherapy and those with advanced-stage cancer (Level I: Doorenbos et al., 2005; Sherwood et al., 2005). Self-management training was beneficial in both group and individual interventions for improving quality of life (Level I: Korstjens et al., 2008). Expressive writing about one’s breast cancer experience significantly improved quality of life outcomes for early-stage breast cancer survivors (Level I: Craft, Davis, & Paulson, 2013).
Interventions for Sexuality
Two articles related to sexuality and sexual function met the criteria for the review, 1 Level I systematic review and 1 Level I RCT.
Moderate Evidence.
Moderate evidence supports exercise as beneficial for prostate cancer patients reporting an interest in sex (Cormie et al., 2013). The systematic review pointed to three types of intervention used for return to sexual function: exercise, medical, and psychoeducational.
Limited Evidence.
Limited evidence supports the effectiveness of couple-based and psychoeducational interventions (Taylor, Harley, Ziegler, Brown, & Velikova, 2011).
Interventions for Return to Work
Three articles related to intervention for return to work met the criteria for the review: 1 Level I systematic review, 1 Level I RCT, and 1 Level III study. Moderate evidence indicates that high-intensity exercise (strength, interval, and home based) helped patients minimize the decrease in work ability after cancer and treatment (Thijs et al., 2012) and that multidisciplinary interventions that include physical and psychological aspects in addition to vocational support provided return-to-work benefits (de Boer et al., 2011). Finally, a Level III study provided limited evidence related to an occupational therapy intervention to help cancer patients return to work (Désiron, 2010).
Discussion
This systematic review examined the evidence for the effectiveness of interventions within the scope of occupational therapy practice to improve the activity and participation needs of adult cancer survivors in all areas of occupation. Part 2 is focused on the effects of multidisciplinary rehabilitation and interventions for psychosocial outcomes, sexuality, and return to work.
Strong evidence indicates that multidisciplinary rehabilitation programs are helpful for cancer survivors regardless of cancer type or stage of cancer. Such programs may be beneficial before treatment of some types of cancer and are beneficial during and after treatment. Moderate to strong evidence indicates that addressing the psychosocial components of cancer survivorship is beneficial for survivors regardless of age or type or stage of cancer and can improve anxiety, depression, and quality of life.
Limited research has been conducted on interventions related to sexuality. This area of rehabilitation is relevant for occupational therapists, and more high-quality studies should be conducted in this area in the future. Moderate evidence supports interventions to address sexuality in cancer patients and survivors. The strongest evidence related to sexuality supports physical exercise for survivors, an important area to address for numerous types of cancer. Return to prediagnosis sexual ability and activity is a goal for many cancer survivors.
Moderate evidence supports rehabilitation interventions addressing return to work for cancer patients and survivors. Return to work is an important part of recovery and rehabilitation for many adults with cancer, but limited research has addressed this component of return to participation. Return to the valued and needed role of worker is important for occupational therapy practitioners to facilitate.
Implications for Occupational Therapy Practice
Cancer rehabilitation interventions benefit patients and survivors with a wide variety of cancers. The evidence demonstrates that this impact takes place at all stages of cancer and at all points on the cancer survivorship continuum. Consequently, occupational therapy practitioners should be involved in all stages of cancer rehabilitation.
The types of services occupational therapy practitioners might provide are broad. Interventions such as problem solving and stress reduction address survivorship issues such as depression, anxiety, and cancer-related fatigue. Return to work is an up-and-coming area in cancer survivorship interventions; current evidence regarding effective strategies for return to work is limited. Research describing the negative effects of not returning to work highlights how important it is to address this area of participation. Finally, occupational therapy providers can work with multidisciplinary teams to address the variety of issues related to psychosocial issues associated with cancer, return to work, and sexuality among cancer survivors.
Implications for Research
In general, more rigorous, well-designed research is needed to understand which people need what type of intervention at what point in their cancer care and survivorship. Specifically, increased research is needed addressing occupational therapy interests such as participation and occupation-based outcomes and interventions. All of the research projects evaluated in this review were within the purview of occupational therapy; however, very few addressed return to participation or included occupation-based interventions.
Rehabilitation services can potentially be incorporated before, during, and after medical treatment. However, little research evidence is available to support clinical decisions such as when to assess survivors, at what point in the cancer continuum services would be optimal, and which survivors are in greatest need of rehabilitation. Sexuality and return to work are two specific areas that are open to opportunities for new research.
Finally, very few of the studies reviewed used specific assessments of function other than health-related quality of life. The majority of studies did not include assessments or outcome measures specifically addressing return to meaningful activity and participation. Future research needs to specifically include participation and return to meaningful activities rather than simply global quality of life.
Limitations
Limitations of the systematic review include the design and methodology of the individual studies, such as small sample sizes, short intervention periods, limited use of standardized assessments, and short follow-up periods. Many of the studies included multiple interventions, so pinpointing the effects of each individual intervention was not always possible. Finally, although comprehensive literature search strategies were used, it is possible that eligible studies were missed and that publication selection bias may have resulted.
Conclusion
Occupational therapy practitioners working with cancer survivors of all types, stages, and points on the survivorship trajectory (diagnosis through long-term survivorship) have some evidence to support practice. The interventions presented in this review are part of an emerging body of research; more research is needed to support occupation-based interventions for this growing population. Occupational therapy practitioners are well suited to investigate occupational performance, occupation-based strategies, quality of life, and participation status to support client-centered interventions before, during, and after treatment of clients with cancer diagnoses.
