Development and Evaluation of a Cancer Literacy Intervention to Promote Mammography Screening Among Navajo Women: A Pilot Study

Health literacy in medical imaging: a scoping review of current evidence and future directions

OBJECTIVE

The importance of health literacy in medical imaging is well recognized, yet the current landscape remains inadequately understood. This study aims to explore the extent of health literacy studies contextualized to medical imaging.

STUDY DESIGN

Scoping review.

METHODS

A scoping review was conducted using three online bibliographic databases namely, PubMed, ScienceDirect, and CINAHL. We have adopted the concept of health literacy, as a clinical risk and personal asset, to guide this review.

RESULTS

Of 311 unique articles, 39 met our selection criteria. Five themes (categories) were identified by the authors: appropriate communication with patients who receive medical imaging test results, appropriate usage of medical imaging, classes and characteristics of eHealth literacy, disease/deterioration prevention, and patient education. Additionally, 17 health literacy assessment tools were identified, including 11 original creations. Finally, 11 recommendations have emerged from this scoping review, offering valuable insights into methods, considerations, and strategies for promoting health literacy.

CONCLUSIONS

Health literacy studies in medical imaging cover both clinical and public health perspectives, benefiting diverse populations, regardless of underlying medical conditions. Notably, the majority of assessment tools used in these studies were author-generated, hindering cross-study comparisons. Given the innate capacity of medical images to convey intuitive information, those images do not solely benefit the patients who are given medical imaging examinations, but they also hold significant potential to enhance public health literacy. Health literacy and medical imaging are closely associated and mutually reinforce each other.

Shared decision-making for supporting women's decisions about breast cancer screening

BACKGROUND

In breast cancer screening programmes, women may have discussions with a healthcare provider to help them decide whether or not they wish to join the breast cancer screening programme. This process is called shared decision-making (SDM) and involves discussions and decisions based on the evidence and the person's values and preferences. SDM is becoming a recommended approach in clinical guidelines, extending beyond decision aids. However, the overall effect of SDM in women deciding to participate in breast cancer screening remains uncertain.

OBJECTIVES

To assess the effect of SDM on women's satisfaction, confidence, and knowledge when deciding whether to participate in breast cancer screening.

SEARCH METHODS

We searched the Cochrane Breast Cancer Group's Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform on 8 August 2023. We also screened abstracts from two relevant conferences from 2020 to 2023.

SELECTION CRITERIA

We included parallel randomised controlled trials (RCTs) and cluster-RCTs assessing interventions targeting various components of SDM. The focus was on supporting women aged 40 to 75 at average or above-average risk of breast cancer in their decision to participate in breast cancer screening.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and conducted data extraction, risk of bias assessment, and GRADE assessment of the certainty of the evidence. Review outcomes included satisfaction with the decision-making process, confidence in the decision made, knowledge of all options, adherence to the chosen option, women's involvement in SDM, woman-clinician communication, and mental health.

MAIN RESULTS

We identified 19 studies with 64,215 randomised women, mostly with an average to moderate risk of breast cancer. Two studies covered all aspects of SDM; six examined shortened forms of SDM involving communication on risks and personal values; and 11 focused on enhanced communication of risk without other SDM aspects. SDM involving all components compared to control The two eligible studies did not assess satisfaction with the SDM process or confidence in the decision. Based on a single study, SDM showed uncertain effects on participant knowledge regarding the age to start screening (risk ratio (RR) 1.18, 95% confidence interval (CI) 0.61 to 2.28; 133 women; very low certainty evidence) and frequency of testing (RR 0.84, 95% CI 0.68 to 1.04; 133 women; very low certainty evidence). Other review outcomes were not measured. Abbreviated forms of SDM with clarification of values and preferences compared to control Of the six included studies, none evaluated satisfaction with the SDM process. These interventions may reduce conflict in the decision made, based on two measures, Decisional Conflict Scale scores (mean difference (MD) -1.60, 95% CI -4.21 to 0.87; conflict scale from 0 to 100; 4 studies; 1714 women; very low certainty evidence) and the proportion of women with residual conflict compared to control at one to three months' follow-up (rate of women with a conflicted decision, RR 0.75, 95% CI 0.56 to 0.99; 1 study; 1001 women, very low certainty evidence). Knowledge of all options was assessed through knowledge scores and informed choice. The effect of SDM may enhance knowledge (MDs ranged from 0.47 to 1.44 higher scores on a scale from 0 to 10; 5 studies; 2114 women; low certainty evidence) and may lead to higher rates of informed choice (RR 1.24, 95% CI 0.95 to 1.63; 4 studies; 2449 women; low certainty evidence) compared to control at one to three months' follow-up. These interventions may result in little to no difference in anxiety (MD 0.54, 95% -0.96 to 2.14; scale from 20 to 80; 2 studies; 749 women; low certainty evidence) and the number of women with worries about cancer compared to control at four to six weeks' follow-up (RR 0.88, 95% CI 0.73 to 1.06; 1 study, 639 women; low certainty evidence). Other review outcomes were not measured. Enhanced communication about risks without other SDM aspects compared to control Of 11 studies, three did not report relevant outcomes for this review, and none assessed satisfaction with the SDM process. Confidence in the decision made was measured by decisional conflict and anticipated regret of participating in screening or not. These interventions, without addressing values and preferences, may result in lower confidence in the decision compared to regular communication strategies at two weeks' follow-up (MD 2.89, 95% CI -2.35 to 8.14; Decisional Conflict Scale from 0 to 100; 2 studies; 1191 women; low certainty evidence). They may result in higher anticipated regret if participating in screening (MD 0.28, 95% CI 0.15 to 0.41) and lower anticipated regret if not participating in screening (MD -0.28, 95% CI -0.42 to -0.14). These interventions increase knowledge (MD 1.14, 95% CI 0.61 to 1.62; scale from 0 to 10; 4 studies; 2510 women; high certainty evidence), while it is unclear if there is a higher rate of informed choice compared to regular communication strategies at two to four weeks' follow-up (RR 1.27, 95% CI 0.83 to 1.92; 2 studies; 1805 women; low certainty evidence). These interventions result in little to no difference in anxiety (MD 0.33, 95% CI -1.55 to 0.99; scale from 20 to 80) and depression (MD 0.02, 95% CI -0.41 to 0.45; scale from 0 to 21; 2 studies; 1193 women; high certainty evidence) and lower cancer worry compared to control (MD -0.17, 95% CI -0.26 to -0.08; scale from 1 to 4; 1 study; 838 women; high certainty evidence). Other review outcomes were not measured.

AUTHORS' CONCLUSIONS

Studies using abbreviated forms of SDM and other forms of enhanced communications indicated improvements in knowledge and reduced decisional conflict. However, uncertainty remains about the effect of SDM on supporting women's decisions. Most studies did not evaluate outcomes considered important for this review topic, and those that did measured different concepts. High-quality randomised trials are needed to evaluate SDM in diverse cultural settings with a focus on outcomes such as women's satisfaction with choices aligned to their values.

American Indian and Alaska Native recruitment strategies for health-related randomized controlled trials: A scoping review

BACKGROUND

Significant health disparities exist among American Indian and Alaska Natives (AI/ANs), yet AI/ANs are substantially underrepresented within health-related research, including randomized controlled trials (RCTs). Although research has previously charted representation inequities, there is however a gap in the literature documenting best practice for recruitment techniques of AI/ANs into RCTs. Therefore, the aim of this review was to systematically gather and analyze the published literature to identify common strategies for AI/AN participant recruitment for RCTs in the US.

METHODS

A scoping review methodology was engaged with a systematic search operationalized within relevant databases to February 19, 2022, with an additional updated search being carried out up until January 1, 2023: PubMed, Embase, Web of Science, PsycINFO, CINAHL, and Google Scholar. A two-stage article review process was engaged with double reviewers using Covidence review software. Content analysis was then carried out within the included articles by two reviewers using NVivo software to identify common categories within the data on the topic area.

RESULTS

Our review identified forty-one relevant articles with the main categories of recruitment strategies being: 1) recruitment methods for AI/ANs into RCTs (passive advertising recruitment approaches, individual-level recruitment approaches, relational methods of recruitment); 2) recruitment personnel used within RCTs; and, 3) relevant recruitment setting. The majority of the included studies used a culturally relevant intervention, as well as a community-involved approach to operationalizing the research.

CONCLUSION

Increasing AI/AN representation in RCTs is essential for generating evidence-based interventions that effectively address health disparities and improve health outcomes. Researchers and funding agencies should prioritize the engagement, inclusion, and leadership of AI/AN communities throughout the RCT research process. This includes early community involvement in study design, implementation of culturally tailored recruitment strategies, and dissemination of research findings in formats accessible to AI/AN communities.

Utilizing Digital Storytelling to Develop a Public Health Professions Pathway for Native American High School Students

Digital storytelling is a decentering methodology in health promotion that positions the storyteller as an expert to create a narrative of their lived experiences. This article describes using a two-phase digital storytelling process within the Diné (Navajo) Educational Philosophy framework to guide the development of a culturally grounded curriculum plan that actively engages Diné youth in exploring health professions pathways in their community. The first phase consisted of developing a high school digital storytelling team by training three Diné youth attending high school on the Navajo Nation located in southwest United States, in digital storytelling. In the second phase, the high school digital storytelling team worked collaboratively with seven Diné students enrolled at the local tribal college to develop digital stories about navigating from high school to college. Data from seven completed digital stories were analyzed with assistance from a community advisory board to identify asset-based themes that contributed to positively transitioning from high school to a tribal college. The results revealed several strategies for successful transitions from high school to a public health college major. The culturally relevant strategies and stories were incorporated into a school-based health professions pathway curriculum plan for Diné youth.

Social determinants of health and US cancer screening interventions: A systematic review

There remains a need to synthesize linkages between social determinants of health (SDOH) and cancer screening to reduce persistent inequities contributing to the US cancer burden. The authors conducted a systematic review of US-based breast, cervical, colorectal, and lung cancer screening intervention studies to summarize how SDOH have been considered in interventions and relationships between SDOH and screening. Five databases were searched for peer-reviewed research articles published in English between 2010 and 2021. The Covidence software platform was used to screen articles and extract data using a standardized template. Data items included study and intervention characteristics, SDOH intervention components and measures, and screening outcomes. The findings were summarized using descriptive statistics and narratives. The review included 144 studies among diverse population groups. SDOH interventions increased screening rates overall by a median of 8.4 percentage points (interquartile interval, 1.8-18.8 percentage points). The objective of most interventions was to increase community demand (90.3%) and access (84.0%) to screening. SDOH interventions related to health care access and quality were most prevalent (227 unique intervention components). Other SDOH, including educational, social/community, environmental, and economic factors, were less common (90, 52, 21, and zero intervention components, respectively). Studies that included analyses of health policy, access to care, and lower costs yielded the largest proportions of favorable associations with screening outcomes. SDOH were predominantly measured at the individual level. This review describes how SDOH have been considered in the design and evaluation of cancer screening interventions and effect sizes for SDOH interventions. Findings may guide future intervention and implementation research aiming to reduce US screening inequities.

Urbanicity, Income, and Mammography-Use Disparities Among American Indian Women

INTRODUCTION

Reported breast cancer screening among American Indian women is consistently below that of White women. The last claims-based trends were from 1991 to 2001. This study updates mammography trends for American Indian women and examines the impact of race, urbanicity, and income on long-term mammography use.

METHODS

This was a multi-year (2005-2019), retrospective study of women aged 40-89 years using a 5% sample of Medicare fee-for-service beneficiaries residing in Arizona, California, New Mexico, Oklahoma, and Washington. This study used multivariable logistic regression to examine the impact of urbanicity and income on receiving mammography for American Indian women compared with that for White women. Analyses were conducted in 2022.

RESULTS

Overall, annual age-adjusted mammography use declined from 205 per 1,000 in 2005 to 165 per 1,000 in 2019. The slope of these declines was significantly steeper (difference = -2.41, p<0.001) for White women (-3.06) than for American Indian women (-0.65). Mammography-use odds across all urbanicity categories were less for American Indian women than for White women compared with those of their respective metropolitan counterparts (e.g., rural: 0.96, 95% CI=0.77, 1.20 for American Indian women and 1.47, 99% CI=1.39, 1.57 for White women). Although residing in higher-income communities was not associated with mammography use for American Indian women, it was 31% higher for White women (OR=1.31, 99% CI=1.28, 1.34).

CONCLUSIONS

The disparity in annual age-adjusted mammography use between American Indian and White women narrowed between 2005 and 2019. However, the association of urbanicity and community income on mammography use differs substantially between American Indian and White women. Policies to reduce disparities need to consider these differences.

An Adapted Cancer Screening Education Program for Native American Women With Intellectual and Developmental Disabilities and Their Caregivers: Protocol for Feasibility and Acceptability Testing

BACKGROUND

Women with intellectual and developmental disabilities (IDD) do not undergo breast and cervical cancer screening at the same rate as women without IDD. IDDs are diagnosed in childhood, are lifelong, and involve difficulties in adaptive behaviors and intellectual functioning. Native American women also experience disparities in breast and cervical cancer screenings. Despite known disparities, women with IDD are often not included in health promotion programs, and there is a need for evidence-based programming for those with intersectional identities, such as Native American women with IDD.

OBJECTIVE

This study aims to assess the feasibility and acceptability of My Health My Choice (MHMC), an adaptation of the Women Be Healthy 2 program. There are 2 parts to the study: adaptation of the Women Be Healthy 2 program and feasibility and acceptability testing of MHMC.

METHODS

Individuals aged over 18 years who identify as Native American females with IDD and their caregivers (N=30 women-caregiver dyads) are eligible for the study. Participants, who are affiliated with 2 partnering sites in Arizona (1 rural and 1 urban), complete pre- and postsurveys assessing knowledge, self-efficacy, and screening expectations before and immediately after completing the program. In addition, all participants complete brief satisfaction surveys after each of the 6 educational sessions. A subsample of Native American women with an IDD (n=12), caregivers (n=12), and community health educators (n=2) who participate in the MHMC program will provide semistructured qualitative input regarding the content, delivery, and cultural relevance of the program.

RESULTS

The adaptation of the culturally responsive MHMC program was completed in August 2021. In November 2021, the project team began recruitment for feasibility and acceptability studies. Feasibility will be examined using participation metrics, and acceptability will be measured using satisfaction measures. Pre- and postmeasures in cancer screening knowledge, self-efficacy, and screening expectations will examine improvements among participants.

CONCLUSIONS

The results of feasibility and acceptability testing of MHMC will guide future implementation studies of the program.

Breast Cancer Screening and Outcomes Disparities Persist for Native American Women

Over the past three decades, mortality rates from breast cancer have decreased for multiple racial groups but have remained constant for American Indian and Alaskan Native (AI/AN) women. Additionally, AI/AN women are less likely to receive timely breast cancer screening and are more likely to be diagnosed with advanced stage breast cancer at younger ages than their White counterparts. These disparities can be explained, in part, by the unique barriers to accessing care faced by AI/AN women. The Indian Health Service provides care to many AI/AN patients; however, their scope of practice is limited, and the service is chronically underfunded, leaving many women without appropriate and timely care. Additionally, geographic access to care is limited because of the sparsity of clinics and limited transportation resources. American Indian and Alaskan Native patients also harbor a history of mistrust in health care systems, and there is a paucity of culturally sensitive education regarding the importance of screening. There have been some grassroots efforts to address these barriers; however, large-scale coordinated efforts are lacking. In order to provide equitable breast health care, more awareness and widescale initiatives are needed and can be championed by breast radiologists.

Comparison of Study Quality as Determined by Standard Research and Community Engagement Metrics: A Pilot Study on Breast Cancer Research in Urban, Rural, and Remote Indigenous Communities

The purpose of this review is to compare research evaluation tools to determine whether the tools typically used for assessing the quality of research adequately address issues of Indigenous health and culture, particularly when the studies are intended to benefit Indigenous peoples in urban, regional, rural, and remote settings. Our previously published systematic review evaluated studies about breast cancer using a modified Indigenous community engagement tool (CET). In this study, we evaluated the same studies using two commonly used tools: the Critical Appraisal Skills Programme (CASP) for qualitative research; and the Effective Public Health Practice Project (EPHPP) for quantitative research. The results were then compared to ascertain whether there was alignment between performances in terms of engagement and the CASP/EPHPP metrics. Of the 15 papers, 3 papers scored weakly on both metrics, and are therefore the least likely to offer reliable findings, while 2 papers scored strongly on both metrics, and are therefore the most likely to offer reliable findings. Beyond this summation, it was clear that the results did not align and, therefore, could not be used interchangeably when applied to research findings intended to benefit Indigenous peoples. There does not appear to be a pattern in the relationship between the reliability of the studies and the study settings. In order to address disparities in health outcomes, we must assess research through a typical research quality and cultural engagement and settings lens, ensuring that there is rigour in all aspects of the studies.

The Relationship Between e-Health Literacy and Breast Cancer Literacy Among Saudi Women

Breast cancer is the most common cancer in women and represents a significant burden among women worldwide. The concept of health literacy is relatively new to the Gulf states, particularly to Saudi Arabia. Research on this topic is scarce, and no study has empirically explored the influence of e-health literacy on breast cancer literacy. The purpose of this study was to measure the impact of e-health literacy on breast cancer literacy among Saudi women in Riyadh city, Saudi Arabia. A cross-sectional survey was conducted online in a cohort of 336 women and disseminated via social media using the e-Health Literacy Scale (eHEALS) and Breast Cancer Literacy Assessment Tool (Breast-CLAT). Multiple regression analysis was executed to identify the sociodemographic factors that influence the e-health literacy and breast cancer literacy of participants. The participants showed high level of e-health literacy with total eHEALS score of 28.79, and better breast cancer literacy with total Breast-CLAT score of 23.44. This study yielded three significant findings: (1) e-health literacy is influenced by age and education which implies that youngest participants showed higher eHEALS scores than their older counterparts and that having increased education level reflected increased eHEALS scores, (2) breast cancer literacy is predicted by education and income which suggests that those who have higher levels of education and higher monthly incomes have increased levels of breast cancer literacy, and (3) breast cancer literacy and e-health literacy were associated which shows that participants with higher eHEALS scores were more likely have increased level of breast cancer literacy. The study revealed that the participants had high level of e-health literacy which correlated to their increased level of breast cancer literacy. The study findings implied that it is important for Saudi women to possess high levels of e-health literacy about breast cancer as more breast cancer educational resources are online nowadays.

Impact of a culturally tailored informative video on cervical cancer: a pilot study with Amazonian women in treatment for cervical cancer

The present study is a randomised pilot study that evaluated a culturally tailored video promoting information about cervical cancer (CC), developed with Amazonian women in treatment for CC. The sample included 63 patients in treatment for CC who were randomly assigned to three groups of 21 patients. The experimental group watched an informative video about CC. The active control group watched a video on healthy habits and the passive control group received no intervention. The groups were compared in terms of change in knowledge and illness perceptions, over time. The results showed that the experimental group was the only one with a significant increase in knowledge (β = .166; p = .03) that was not maintained over time (β = -.195; p = .04). Threatening illness perceptions about the disease increased in all groups over time (β = .105; p = .001). Future studies should replicate the results testing the efficacy of an audiovisual strategy in a larger sample, in health services that serve populations with similar social and cultural characteristics. This study emphasises the importance of interprofessional oncology teams providing clear information regarding CC, during all stages of the disease, and patients' treatment.Impact StatementWhat is already known on this subject? Latin American countries, such as Brazil, the low coverage of screening for CC can be related to the low education of women and their difficulty of access to health care. Hence, educational interventions may be a good strategy to reinforce the importance of screening and increase knowledge about illness prevention and treatment.What the results of this study add? An audiovisual informational intervention on CC was developed, addressing prevention, causes, control, consequences and treatment while respecting the patients' cultural and social reality through an approach that is simple and easy to understand. The group that watched the informative video was the only one that increased knowledge, revealing that it was a good CC informational strategy.What are the implications of these findings for clinical practice and/or further research? This study confirmed the importance of developing informational and educational strategies that are appropriate to patients' social and cultural reality. The video is now available to health teams in primary, secondary and tertiary care units, as a strategy for health promotion and CC prevention.

What Is the Evidence Globally for Culturally Safe Strategies to Improve Breast Cancer Outcomes for Indigenous Women in High Income Countries? A Systematic Review

The aim was to systematically assess the evidence on whether cultural safety affects breast cancer outcomes with regards to care for Indigenous women in high income countries. We conducted a systematic review in accordance with PRISMA guidelines of peer-reviewed articles in Medline, EMBASE, CINAHL, Scopus, Web of Science, Proquest Sociology and Informit Rural health database and Indigenous collection databases. Key inclusion criteria were: adult female patients with breast cancer; high income country setting; outcome measure, including screening, diagnosis, treatment and follow up care. A total of 15 were selected. We developed a Community Engagement assessment tool in consultation with aboriginal researchers, based on the National Health and Medical Research Councils' community engagement guidelines, against which studies were appraised. This novel element allowed us to evaluate the literature from a new and highly relevant perspective. Thematic analysis of all 15 studies was also undertaken. Despite limited literature there are evidence-based strategies that are likely to improve outcomes for Indigenous women with breast cancer in high income countries and indicate that culture makes a positive difference. It is also clear that strong Indigenous community leadership and governance at all stages of the research including design is an imperative for feasibility.

A Qualitative Focus Group Study for the Exploration of Knowledge and Attitudes of Informal Caregivers Toward Breast Cancer: Perceptions of Informal Caregivers and Healthcare Professionals in Three European Countries

Breast cancer (BC) early screening and detection is a main component for the outcome of the treatment and overall survival. Informal caregivers (ICGs) are less likely to initiate early BC screening methods and utilize health services. The purpose of this study was to explore ICGs’ knowledge and perceptions, including educational and training opportunities or barriers, in promoting early detection practices for BC, as well as healthcare professionals’ (HCP) respective perceptions concerning ICGs in order to identify the need of selected health literacy interventions. A qualitative focus group study was implemented in 3 European countries, using a purposive sampling technique. In total, 26 ICGs and 18 HCPs were involved. The themes that emerged from the focus groups interviews included knowledge, perceptions, attitudes, and beliefs concerning BC; motivational factors and barriers that influence early screening practices and personal involvement. Motivators and barriers concerning BC screening adherence were linked to knowledge, beliefs and perceptions. Health promotion strategies and user-friendly tools should be developed, targeting on the implementation of BC early detection practices among informal caregivers.
