Peer Support as an Ideal Solution for Racial/Ethnic Disparities in Colorectal Cancer Screening: Evidence from a Systematic Review and Meta-analysis

A peer support intervention in patients with hematologic malignancies undergoing hematopoietic stem cell transplantation (HSCT): The STEPP randomized pilot trial design and methods

BACKGROUND

Despite the association between peer support interventions and improved patient-reported outcomes (PROs) across cancer populations, there is a lack of structured peer support interventions for patients with hematologic malignancies undergoing hematopoietic stem cell transplantation (HSCT).

OBJECTIVE

To test the feasibility, acceptability, and preliminary efficacy of a novel five-session, phone-delivered peer support intervention (STEPP: Supporting Transplant Experiences with Peer Program) for improving quality of life (QOL) and reducing psychological distress in patients undergoing HSCT.

METHODS

This single-center pilot randomized clinical trial (RCT) will compare the STEPP intervention to usual transplant care among 90 patients hospitalized for HSCT. Eligible participants include adults (age ≥ 18 years) with hematologic malignancies hospitalized for autologous or allogeneic HSCT. The STEPP intervention provides informational, emotional, and practical support. To test the primary aim of intervention feasibility, we have established a priori benchmarks of 60 % enrollment of eligible patients and 60 % completion of at least 3 out of 5 intervention sessions among those randomized to STEPP. Acceptability will be assessed using the Client Satisfaction Questionnaire, with scores ≥3.0/4.0 indicating greater intervention acceptability. To test the secondary aim of preliminary efficacy, we will examine changes in PROs (e.g., anxiety symptoms and QOL) from pre- to post-intervention.

DISCUSSION

This pilot RCT of a structured, phone-delivered peer support intervention tailored to the needs of patients preparing to undergo HSCT will elucidate the feasibility, acceptability, and preliminary efficacy of the STEPP intervention. We will then be poised to conduct a future, full-scale RCT to establish the efficacy of STEPP on patient outcomes.

Transitional care programs to improve the post-discharge experience of patients with multiple chronic conditions and co-occurring serious mental illness: A scoping review

The transition from hospital to home can be especially challenging for those with multiple chronic conditions and co-occurring serious mental illness (SMI). This population tends to be Medicaid-insured and disproportionately experiences health-related social needs. The aim of this scoping review was to identify the elements and outcomes of hospital-to-home transitional care programs for people diagnosed with SMI. A scoping review was conducted using Arksey and O'Malley's methodology. Three databases were searched; ten articles describing eight transitional care programs published from 2013 to 2024 met eligibility criteria. Five programs focused on patients being discharged from a psychiatric admission. Five of the interventions were delivered in the home. Intervention components included coaching services, medication management, psychiatric providers, and counseling. Program lengths ranged from one month to 90 days post-hospitalization. These programs evaluated quality of life, psychiatric symptoms, medication adherence, readmissions, and emergency department utilization. Notably, few programs appeared to directly address the unmet social needs of participants. While the focus and components of each transitional care program varied, there were overall positive improvements for participants in terms of improved quality of life, increased share decision making, and connections to primary and specialty care providers.

Preferences for Peer Support Amongst Families Engaged in Paediatric Screening Programmes: The Perspectives of Parents Involved in Screening for Type 1 Diabetes in Children Aged 3-13

INTRODUCTION

This work describes a secondary analysis of a qualitative data set originally used to understand parent participants' preferences for the design and implementation of a screening programme for paediatric Type 1 diabetes (T1D). From this, their spontaneous preferences for peer support emerged, described here in the context of existing peer support programmes for the newly diagnosed alongside suggestions for their incorporation into screening programmes for T1D and a range of other conditions.

METHODS

Data were collected from semi-structured interviews conducted with parents of children aged 3-13 years to explore their expectations, perceptions and preferences of a T1D paediatric screening programme. A secondary analysis of interviews from participants who spontaneously raised preferences for peer support was used to populate a novel framework informed by NHS England's key principles for the same, namely, Shared experiences and reciprocated support, Accessibility and inclusivity and Person-centred and integrated peer support.

RESULTS

Parents in 29 of 33 interviews spontaneously described the potential value of peer support if receiving a result indicating a positive (presymptomatic T1D result) from a screening programme. Specifically, the value of 'Shared experiences and reciprocated support' in terms of emotional support and reassurance, and access to more directly interpretable and relevant information related to the condition; 'Accessibility and inclusivity' relating to access to a community of similar individuals, whether in person or online; 'Person-centred and integrated peer-support' and the need for support reflecting the changing need of the child and the integration of peer support with clinical care.

CONCLUSIONS

The needs of peer support described by parents involved in T1D paediatric screening appear to be shared with those of families with children diagnosed with a range of life-altering conditions. Although the needs of peer support for paediatric screening may differ across conditions, our findings are a valuable starting point for its design both in T1D and other examples of similar population screening programmes.

Prevalence and predictors of colorectal cancer screening in the United States: evidence from the HINTS database 2018 to 2020

BACKGROUND

The incidence of colorectal cancer (CRC) and CRC-related mortality among young adults (< 50 years) has been on the rise. The American Cancer Society (ACS) reduced the CRC screening age to 45 in 2018. Few studies have examined the barriers to CRC screening among young adults.

METHODS

Analyses were conducted using data from 7,505 adults aged 45-75 years who completed the 2018 to 2020 Health Information National Trends Survey. We examined the sociodemographic characteristics associated with CRC screening overall and by age group using separate multivariable logistic regression models.

RESULTS

76% of eligible adults had received screening for CRC. Increasing age, Black racial group [OR 1.45; 95% CI (1.07, 1.97)], having some college experience, a college degree or higher [OR 1.69; 95% CI (1.24, 2.29)], health insurance coverage [OR 4.48; 95% CI (2.96, 6.76)], primary care provider access [OR 2.48; 95% CI (1.91, 3.22)] and presence of a comorbid illness [OR 1.39; 95% CI (1.12, 1.73)] were independent predictors of CRC screening. Current smokers were less likely to undergo CRC screening [OR 0.59; 95% CI (0.40, 0.87)]. Among adults aged 50-64 years, being of Hispanic origin [OR 0.60; 95% CI (0.39, 0.92)] was associated with a lower likelihood of CRC screening.

CONCLUSION

CRC screening rates among adults 45-49 years are low but are increasing steadily. Odds of CRC screening among Blacks is high which is encouraging while the odds among current smokers is low and concerning given their increased risk of developing CRC.

Influence of social support and stressful life events on adherence to colorectal cancer screening using faecal occult blood test in Spanish medium risk population

INTRODUCTION

Colorectal cancer (CRC) is the second cause of cancer-related deaths worldwide. Five-year survival rate in Spain is 57%. The most important prognostic factor is the stage of the tumor at the diagnosis. CRC can be early diagnosed, but the adherence to screening programs is low (<50%). This study aims to ascertain the influence of social support and stressful life events on the adherence to the population screening of CRC with fecal occult blood test in Spanish average risk population.

METHODS

Multicenter case-control study. We conducted a simple random sampling among individuals invited to participate in the colorectal cancer screening program. We analyzed epidemiological and social variables associated with lifestyle and behavioral factors. We performed a descriptive and a bivariant analyses and a logistic regression analysis.

RESULTS

Four hundred and eight patients (237 cases and 171 controls) were included. Multivariant analyses showed independent association between higher adherence to the screening program and older age (OR: 1.06; 95% CI: 1.01-1.10), stable partner (OR: 1.77, 95% CI: 1.08-2.89) and wide social network (OR: 1.68; 95% CI: 1.07-2.66). Otherwise, lower adherence was associated to perceiving barriers to participate in the program (OR: 0.92; 95% CI: 0.88-0.96). We find a statistically significant association between lower adherence and high impact stressful life events in the bivariant analyses, and the tendency was maintained (OR: 0.63, 95% CI: 0.37-1.08) in the multivariant.

CONCLUSION

Social variables decisively influence the adherence to colorectal cancer screening. The implementation of social interventions that improve social support, reduce impact of stressful life events and the design of screening programs that decrease the perceived barriers, will contribute to increase the participation on these programs. Secondary, the colorectal cancer diagnosis will be made in early-stages with the consequent mortality reduction.

Patient navigation across the cancer care continuum: An overview of systematic reviews and emerging literature

Patient navigation is a strategy for overcoming barriers to reduce disparities and to improve access and outcomes. The aim of this umbrella review was to identify, critically appraise, synthesize, and present the best available evidence to inform policy and planning regarding patient navigation across the cancer continuum. Systematic reviews examining navigation in cancer care were identified in the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, Cumulative Index of Nursing and Allied Health (CINAHL), Epistemonikos, and Prospective Register of Systematic Reviews (PROSPERO) databases and in the gray literature from January 1, 2012, to April 19, 2022. Data were screened, extracted, and appraised independently by two authors. The JBI Critical Appraisal Checklist for Systematic Review and Research Syntheses was used for quality appraisal. Emerging literature up to May 25, 2022, was also explored to capture primary research published beyond the coverage of included systematic reviews. Of the 2062 unique records identified, 61 systematic reviews were included. Fifty-four reviews were quantitative or mixed-methods reviews, reporting on the effectiveness of cancer patient navigation, including 12 reviews reporting costs or cost-effectiveness outcomes. Seven qualitative reviews explored navigation needs, barriers, and experiences. In addition, 53 primary studies published since 2021 were included. Patient navigation is effective in improving participation in cancer screening and reducing the time from screening to diagnosis and from diagnosis to treatment initiation. Emerging evidence suggests that patient navigation improves quality of life and patient satisfaction with care in the survivorship phase and reduces hospital readmission in the active treatment and survivorship care phases. Palliative care data were extremely limited. Economic evaluations from the United States suggest the potential cost-effectiveness of navigation in screening programs.

The impact of social media on guideline-concordant cervical cancer-screening: insights from a national survey

OBJECTIVES

Cervical cancer is one of the leading causes of cancer mortality in women, yet routine screenings lead to early detection and sometimes even prevention. Screening is an effective way to prevent cervical cancer, and it has been implemented in many countries and regions worldwide, especially in developed countries. However, the incidence of cervical cancer remains a public health problem due to screening disparities in the population. Social media engagement and overloading of online health information may be the cause of this disparity.

STUDY DESIGN

Cross-sectional study.

METHODS

Data from the Health Information National Trends Survey (a national survey conducted by the National Cancer Institute) was used to characterise cervical cancer screening into two dimensions; namely, high-frequency screening and guideline-concordant screening. The differences between these two screening frequency behaviours were compared by applying ordered logistic regression and binary logistic regression, and the mechanisms of guideline-concordant screening were explored.

RESULTS

The factors influencing high-frequency screening and guideline-concordant screening were different. Only self-efficacy (odds ratio [OR] = 1.16; 95% confidence interval [CI] = 0.98, 1.37) had a significant positive association with the high-frequency screening behaviour. Social media engagement (OR = 0.57; 95% CI = 0.33, 0.96) was shown to have a significant negative impact on guideline-concordant screening. A theory-based mechanism of screening behaviour found that traditional health perception factors no longer influence guideline-concordant screening behaviour, whereas environmental factors (e.g., social media) significantly reduce guideline-concordant screening behaviour.

CONCLUSIONS

The results from this study indicate that while the internet has become the main channel through which women acquire health resources, and social media has become a main platform for people to obtain health information, online information cannot guide people to engage in appropriate healthy behaviours. Overloading of online health information and the digital divide may lead to excessive screening. Consequently, it is important to address the screening disparity caused by health behaviours as a result of environmental factors and the digital divide.

Towards evidence-based and inclusive models of peer support for long covid: A hermeneutic systematic review

Since the first wave of COVID-19 in March 2020 the number of people living with post-COVID syndrome has risen rapidly at global pace, however, questions still remain as to whether there is a hidden cohort of sufferers not accessing mainstream clinics. This group are likely to be constituted by already marginalised people at the sharp end of existing health inequalities and not accessing formal clinics. The challenge of supporting such patients includes the question of how best to organise and facilitate different forms of support. As such, we aim to examine whether peer support is a potential option for hidden or hardly reached populations of long COVID sufferers with a specific focus on the UK, though not exclusively. Through a systematic hermeneutic literature review of peer support in other conditions (57 papers), we evaluate the global potential of peer support for the ongoing needs of people living with long COVID. Through our analysis, we highlight three key peer support perspectives in healthcare reflecting particular theoretical perspectives, goals, and understandings of what is 'good health', we call these: biomedical (disease control/management), relational (intersubjective mutual support) and socio-political (advocacy, campaigning & social context). Additionally, we identify three broad models for delivering peer support: service-led, community-based and social media. Attention to power relations, social and cultural capital, and a co-design approach are key when developing peer support services for disadvantaged and underserved groups. Models from other long-term conditions suggest that peer support for long COVID can and should go beyond biomedical goals and harness the power of relational support and collective advocacy. This may be particularly important when seeking to reduce health inequalities and improve access for a potentially hidden cohort of sufferers.

What is the volume, diversity and nature of recent, robust evidence for the use of peer support in health and social care? An evidence and gap map

Background

Peer support interventions involve people drawing on shared personal experience to help one another improve their physical or mental health, or reduce social isolation. If effective, they may also lessen the demand on health and social care services, reducing costs. However, the design and delivery of peer support varies greatly, from the targeted problem or need, the setting and mode of delivery, to the number and content of sessions. Robust evidence is essential for policymakers commissioning peer support and practitioners delivering services in health care and community settings. This map draws together evidence on different types of peer support to support the design and delivery of interventions.

Objectives

The aim of this map was to provide an overview of the volume, diversity and nature of recent, high quality evidence on the effectiveness and cost-effectiveness of the use of peer support in health and social care.

Search Methods

We searched MEDLINE, seven further bibliographic databases, and Epistemonikos for systematic reviews (in October 2020), randomised controlled trials (in March 2021) and economic evaluations (in May 2021) on the effectiveness of peer support interventions in health and social care. We also conducted searches of Google Scholar, two trial registers, PROSPERO, and completed citation chasing on included studies.

Selection Criteria

Systematic reviews, randomised controlled trials and economic evaluations were included in the map. Included studies focused on adult populations with a defined health or social care need, were conducted in high-income countries, and published since 2015. Any measure of effectiveness was included, as was any form of peer support providing the peer had shared experience with the participant and a formalised role.

Data Collection and Analysis

Data were extracted on the type of peer support intervention and outcomes assessed in included studies. Standardised tools were used to assess study quality for all studies: assessing the methodological quality of systematic reviews 2 for systematic reviews; Cochrane risk of bias tool for randomised controlled trials; and consensus health economic criteria list for economic evaluations.

Main Results

We included 91 studies: 32 systematic reviews; 52 randomised controlled trials; and 7 economic evaluations. Whilst most included systematic reviews and economic evaluations were assessed to be of low or medium quality, the majority of randomised controlled trials were of higher quality. There were concentrations of evidence relating to different types of peer support, including education, psychological support, self-care/self-management and social support. Populations with long-term health conditions were most commonly studied. The majority of studies measured health-related indicators as outcomes; few studies assessed cost-effectiveness. Studies were unevenly distributed geographically, with most being conducted in the USA. Several gaps were evident regarding the delivery of peer support, particularly the integration of peers and professionals in delivering support and interventions of longer duration.

Authors' Conclusions

Although there is evidence available to inform the commissioning and delivery of peer support in health and social care, there are also clear gaps that need to be addressed to further support provision, particularly regarding cost-effectiveness. The effectiveness of peer support in different countries, with varying health and social care systems, is a priority for future research, as is the integration of peers with professionals in delivering peer support.

Peer Education and Peer Counselling for Health and Well-Being: A Review of Reviews

Peer education and peer counselling for health and wellbeing have been recognized as complementary approaches to professional intervention for over 50 years, but it is relatively recently that research into effects has become adequate. Potentially, they have advantages in reaching where professionals cannot, but it has not been clear if that potential is fulfilled, although the measurement of effects is difficult. The present paper examines 58 narrative and systematic reviews and meta-analyses on the topic. In peer education, there were many reviews of sexual health and of HIV/AIDS interventions, followed by reviews of various medical conditions and in the context of prisons. More general reviews covered a wider field. In peer counselling, there were several reviews of breast-feeding and mental health. Many early reviews complained of the lack of evaluation; then, later reviews found knowledge gains but not behavior gains; then, still later reviews found both knowledge and behavior gains. Thus, peer education and counselling appear effective but only if organizational factors are well managed and the cultural context of the country respected. The implications for future practice, policy and research were outlined.

Empowerment in cancer patients: Does peer support make a difference? A systematic review

OBJECTIVE

Empowerment is critical for cancer patients to make informed choices, to manage medication, and to navigate through the oncological care system. Cancer peer support provides patients with information, emotional relief and may promote empowerment. This paper provides a systematic review of the literature examining the impact of cancer peer support interventions on psychological empowerment.

METHODS

PubMed, Web of Science, CINAHL, Cochrane Library, PsycINFO and PSYNDEX databases were systematically searched from inception until December 2020. We included quantitative studies, published in English or German, which examined peer-led cancer support interventions and their impact on the three components of psychological empowerment (intrapersonal, interactional and behavioural) among participating cancer patients.

RESULTS

Database searches and screening of relevant reference lists identified 2336 potentially relevant articles. A total of 29 studies were included in the review. Active coping, self-efficacy and knowledge were the most prominent dimensions of empowerment in these studies. The majority of studies revealed that peer support led to a small to medium, significant increase in psychological empowerment, and was associated with further patient-reported benefits.

CONCLUSIONS

The existing evidence suggests a weak to moderate, positive association between cancer peer support and the three components of psychological empowerment among cancer patients. Peer support groups should be seen as an important element in cancer care and clinical practice and, thus, be more systematically involved in cancer care.

Improving our model of cascade testing for hereditary cancer risk by leveraging patient peer support: a concept report

Consensus and evidence suggest that cascade testing is critical to achieve the promise of cancer genetic testing. However, barriers to cascade testing include effective family communication of genetic risk information and family members' ability to cope with genetic risk. These barriers are further complicated by the developmental needs of unaffected family members during critical windows for family communication and adaptation. Peer support could address these barriers. We provide two illustrative examples of ongoing BRCA1/2-related clinical trials that apply a peer support model to improve family communication and functioning. Peer support can augment currently available genetic services to facilitate adjustment to and effective use of cancer genetic risk information. Importantly, this scalable approach can address the presence of cancer risk within families across multiple developmental stages. This applies a family-centered perspective that accommodates all potentially at-risk relatives. This peer support model can be further applied to emerging topics in clinical genetics to expand reach and impact.

The SWIM study: Ethnic minority women's ideas and preferences for a tailored intervention to promote national cancer screening programmes-A qualitative interview study

BACKGROUND

Ethnic minority women from non-Western countries are less likely than the native women to participate in screening programmes for cervical cancer, breast cancer and colorectal cancer. This social inequality can result in loss of possibility for prevention, delayed diagnosis and treatment and, ultimately, lower chance of survival. Developing a tailored intervention might be the solution to reduce social inequalities in cancer screening, and a key feature in intervention research is to consult the target group.

OBJECTIVE

To explore ethnic minority women's own ideas and preferences for a cancer screening intervention and identify their attitudes to different strategies.

METHODS

An interview study with five focus group interviews, two group interviews with an interpreter and three individual interviews. Thirty-seven women from 10 non-Western countries contributed to the study. The interviews were audio-recorded and transcribed verbatim followed by a thematic analysis.

RESULTS

According to the women, a tailored intervention should focus on knowledge in the form of face-to-face teaching. The women further suggested information material in their own language with a simple, positive and concrete communication strategy. They would like to be involved in an awareness strategy and share the knowledge with their network.

CONCLUSION

Ethnic minority women were interested in a tailored intervention, and they were keen to contribute with ideas and preferences. The findings emphasized the potential of a tailored intervention with specific suggestions to the content when attempting to reduce inequality in cancer screening participation.

PATIENT OR PUBLIC CONTRIBUTION

Minority women were involved in the interview study.

Factors associated with breast cancer screening intention in Kathmandu Valley, Nepal

Background

Breast cancer burden is increasing in low-income countries (LICs). Increasing incidence and delayed presentation of breast cancer are mainly responsible for this burden. Many women do not participate in breast cancer screening despite its effectiveness. Moreover, studies are limited on the barriers associated with low utilization of breast cancer screening in LICs. This study identified breast cancer screening behavior and factors associated with breast cancer screening intention among women in Kathmandu Valley, Nepal.

Methods

A cross-sectional study was conducted among 500 women living in five municipalities of Kathmandu Valley, Nepal. Data were collected from July to September 2018, using a structured questionnaire. Interviews were conducted among women selected through proportionate random household sampling. This study was conceptualized using the theory of planned behavior, fatalism, perceived susceptibility, and perceived severity. The outcome variables included: the intention to have mammography (MMG) biennially, the intention to have clinical breast examination (CBE) annually, and the intention to perform breast self-examination (BSE) monthly. Analysis was conducted separately for each outcome variable using partial proportional odds model.

Results

Out of 500 women, 3.4% had undergone MMG biennially, 7.2% CBE annually, and 14.4% BSE monthly. Women with a positive attitude, high subjective norms, and high perceived behavioral control were more likely to have the intention to undergo all three screening methods. Similarly, women were more likely to have intention to undergo CBE and MMG when they perceived themselves susceptible to breast cancer. Conversely, women were less likely to have intention to undergo CBE when they had high fatalistic beliefs towards breast cancer.

Conclusion

Women in this study had poor screening behavior. The practice of breast self-examination was comparatively higher than clinical breast examination and mammography. Multidimensional culturally sensitive interventions are needed to enhance screening intentions. Efforts should be directed to improve attitude, family support, and fatalistic belief towards cancer. Furthermore, the proper availability of screening methods should be ensured while encouraging women to screen before the appearance of symptoms.
