Information Mismatch: Cancer Risk Counseling with Diverse Underserved Patients

Assessing interventions promoting the uptake of cancer-related genomic services within the Latino community: A scoping review using the RE-AIM framework

Cancer genomic services (CGS) can support genetic risk-stratified cancer prevention and treatment. Racial/ethnic minority groups are less likely to access and utilize CGS compared with non-Hispanic Whites. Little research has described characteristics of interventions targeted at CGS among Latinos. This scoping review aimed to (1) describe interventions promoting uptake of CGS among Latinos in the United States and Latin America, (2) describe intervention adaptations for Latino participants, and (3) summarize intervention implementation factors suggested by reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) framework. We conducted a search in English and Spanish of literature published between 2005 and 2022 across PubMed and Latin American and Caribbean Health Sciences Literature databases. Sixteen of 2344 papers met the inclusion criteria of the analysis. Efforts to promote CGS among Latino communities were limited in the US and lower in Latin America. This review highlights the need for in-depth exploration of acculturation-informed interventions and better reporting on implementation factors to enhance their scalability across diverse settings.

The Effects of Animations and Multimedia Messages on Public Engagement in Precision Medicine: Assessment of Moderation and Mediation

Public participation in precision medicine (PM) research is essential to achieving effective health care but has been impeded by a lack of awareness and basic knowledge. There is a critical need for educational materials that can clearly explain PM to foster involvement. This randomized controlled trial with a posttest-only control group design aims to assess the effects of educational messages delivered through animations relative to live-action videos and leaflets on intentions of involvement in PM research. Knowledge as the moderator and four mediators (engagement, vividness, trustworthiness, and cognitive value) of the intended effects were also evaluated. A total of 326 U.S. adults were sampled from Amazon Mechanical Turk. Among participants with less knowledge about PM, animations produced stronger information-seeking intentions and willingness to participate than leaflets. The effects of three message modalities were not significantly different among average and highly knowledgeable participants. Engagement and vividness mediated the effects of animations relative to two other message modalities. Trustworthiness and cognitive value mediated the effects of animations relative to live-action videos. Overall, animations can be an effective communication strategy to motivate involvement in PM but its effectiveness could decline as knowledge increases. The explanations and implications of the findings were discussed.

Challenges to genetic testing for germline mutations associated with breast cancer among African Americans

Inequities in preventive cancer screening, diagnosis, treatment, and inferior cancer outcomes continue to pose challenges across the cancer continuum. While the exact reasons for these inferior outcomes are unknown, multiple barriers to various domains of social determinants of health (SDOH) play a vital role, leading to inequities in cancer care. These include barriers to transportation, housing, and food insecurities, contributing to delays in preventive screening and treatment. Furthermore, aggressive biologies also exist across various racial profiles with accompanying germline mutations. For example, African Americans (AAs) have a higher incidence of triple-negative breast cancer subtype and a high prevalence of BRCA1/2 gene mutations, increasing the risk of multiple cancers, warranting high-risk screening for these populations. Unfortunately, other barriers, such as financial insecurities, low health literacy rates, and lack of awareness, lead to delays in cancer screening and genetic testing, even with available high-risk screening and risk reduction procedures. In addition, physicians receive minimal interdisciplinary training to address genetic assessment, interpretation of the results, and almost no additional training in addressing the unique needs of racial minorities, leading to suboptimal delivery of genetic assessment provision resources among AAs. In this review, we discuss the confluence of factors and barriers limiting genetic testing among AAs and highlight the prevalence of germline mutations associated with increased risk of breast cancer among AAs, reflecting the need for multi-panel germline testing as well as education regarding hereditary cancer risks in underserved minorities.

Participant-guided development of bilingual genomic educational infographics for Electronic Medical Records and Genomics Phase IV study

OBJECTIVE

Developing targeted, culturally competent educational materials is critical for participant understanding of engagement in a large genomic study that uses computational pipelines to produce genome-informed risk assessments.

MATERIALS AND METHODS

Guided by the Smerecnik framework that theorizes understanding of multifactorial genetic disease through 3 knowledge types, we developed English and Spanish infographics for individuals enrolled in the Electronic Medical Records and Genomics Network. Infographics were developed to explain concepts in lay language and visualizations. We conducted iterative sessions using a modified "think-aloud" process with 10 participants (6 English, 4 Spanish-speaking) to explore comprehension of and attitudes towards the infographics.

RESULTS

We found that all but one participant had "awareness knowledge" of genetic disease risk factors upon viewing the infographics. Many participants had difficulty with "how-to" knowledge of applying genetic risk factors to specific monogenic and polygenic risks. Participant attitudes towards the iteratively-refined infographics indicated that design saturation was reached.

DISCUSSION

There were several elements that contributed to the participants' comprehension (or misunderstanding) of the infographics. Visualization and iconography techniques best resonated with those who could draw on prior experiences or knowledge and were absent in those without. Limited graphicacy interfered with the understanding of absolute and relative risks when presented in graph format. Notably, narrative and storytelling theory that informed the creation of a vignette infographic was most accessible to all participants.

CONCLUSION

Engagement with the intended audience who can identify strengths and points for improvement of the intervention is necessary to the development of effective infographics.

Genetic counselling resources in non-english languages: A scoping review

Objective

Genetic counselling is essential for individuals seeking genetic or genomic testing. Whereas innovative strategies for GC delivery are being explored to meet the growing demand on the clinical genetics workforce, it is essential to consider the unique needs of culturally and linguistically diverse populations.

Methods

We conducted a scoping review to examine the extent, range, and gaps in the body of non-English, patient-facing educational resources available for Limited English Proficient (LEP) patients accessing clinical genetics and genomics services.

Results

The literature search returned 246 unique resources, most available in several languages. Forty-six languages were represented, with Spanish, Russian, and French being the most common. Resources were in various formats and were of varying quality.

Conclusions

There is a lack of high-quality supplementary genetics education material available in languages other than English, which limits the quality-of-care that LEP families may receive compared to their English-speaking counterparts. Of equal concern is the difficulty in finding existing resources and in determining their quality.

Innovation

This research highlights the important need for genetics education material that is of good quality in languages other than English and the challenges associated with identifying this material. A central, curated repository, perhaps sponsored by a genetic counselling organization, would be of great benefit to help genetic counsellors meet the needs of their culturally and linguistically diverse patients.

Genetic counseling and testing for females at elevated risk for breast cancer: Protocol for the randomized controlled trial of the Know Your Risk intervention

BACKGROUND

Genetic counseling and testing have an important role in the care of patients at elevated risk for breast cancer. However, conventional pre- and post-test genetic counseling is labor and time intensive, less accessible for patients living outside major urban centers, and impractical on a large scale. A patient-driven approach to genetic counseling and testing may increase access, improve patients' experiences, affect efficiency of clinical practice, and help meet workforce demand. The objective of this 2-arm randomized controlled trial is to determine the efficacy of Know Your Risk (KYR), a genetic counseling patient preference intervention.

METHODS

Females (n = 1000) at elevated risk (>20% lifetime) for breast cancer will be randomized to the KYR intervention or conventional genetic counseling. The study will provide comprehensive assessment of breast cancer risk by multigene panel testing and validated polygenic risk score. Primary outcome is adherence to National Comprehensive Cancer Network guidelines for a clinical encounter every 6-12 months and an annual mammogram (breast MRI if recommended) determined by medical record review. Secondary outcomes include adherence to other recommended cancer screening tests determined by medical record review and changes in breast cancer knowledge, perception of risk, post-test/counseling distress, and satisfaction with counseling by completion of three surveys during the study. Study aims will be evaluated for non-inferiority of the KYR intervention compared to conventional genetic counseling.

CONCLUSION

If efficacious, the KYR intervention has the potential to improve patients' experience and may change how genetic counseling is delivered, inform best practices, and reduce workforce burden.

Effective communication with linguistically diverse patients: A concept analysis

OBJECTIVE

Effective communication is essential to providing high-quality healthcare. For linguistically diverse patients, communication remains a barrier to receiving equitable healthcare throughout the globe. It is necessary to examine the concept of effective communication with linguistically diverse patients.

METHODS

The Walker and Avant method was used to analyze the concept.

RESULTS

We define effective communication with linguistically diverse patients as any verbal or written communication between two or more individuals who do not speak the same language that utilizes accurate translation techniques to reach a shared message or understanding, where all parties involved are listened to and actively engaged. The antecedents, attributes, consequences, and empirical referents are mapped.

CONCLUSION

Effective communication with linguistically diverse patients is limited by a lack of access to professional language assistance, structural racism/discrimination, and policy barriers.

PRACTICE IMPLICATIONS

Healthcare workers hold the power to provide language assistance to patients and should therefore receive training in cultural competency, cultural humility, and how to work with professional medical interpreters and language access programs. Institutions should invest in multimodal approaches to provide equitable healthcare to linguistically diverse patients.

Piloting a Spanish-Language Web-Based Tool for Hereditary Cancer Genetic Testing

The delivery of hereditary cancer pre-test education among Spanish-language patients is impeded by the dearth of Spanish-speaking genetic counselors. To address this gap, we evaluated a web-based genetic education tool delivered in Spanish to provide information typically discussed during an initial genetic counseling session. Spanish-speaking patients with a personal or family history of cancer were recruited at two centers in Puerto Rico and through social media. A total of 41 participants completed a survey before and after viewing the tool to measure knowledge, attitudes, and decisional empowerment. A subset of 10 participants completed a virtual semi-structured interview to assess the usability and appropriateness of the tool. Paired t-tests were calculated to evaluate changes in knowledge and attitudes. A McNemar test assessed for decisional empowerment. Interview transcripts were translated from Spanish to English and inductively coded and analyzed. Results revealed significant increases in knowledge (p < 0.001), while attitudes about genetic testing did not change (p = 0.77). The proportion of individuals who felt fully informed and empowered to decide about whether to undergo genetic testing increased from 15% to 51% (p < 0.001). Qualitative data indicated that participants found the tool easy to use with informative and valuable content. Our findings suggest this Spanish-language tool is a user-friendly and scalable solution to help inform and empower many individuals to decide about cancer genetic testing, recognizing that others may still benefit from genetic counseling prior to testing.

Communication Dimensions of Healthcare Engagement and Patient Health Literacy for Immigrant Populations: A Systematic Review

Health literacy is an important social determinant of health. Achieving health literacy of immigrants can be critical to empower this disadvantaged population in healthcare communication. However, to achieve this goal, it is a prerequisite to examine the relationship between health literacy and patient engagement in healthcare communication. This systematic review conceptualizes behavioral, emotional, and cognitive dimensions of patient engagement in healthcare communication and examines how health literacy and patient engagement among immigrants shape each other. A systematic review was conducted to identify relevant articles from five databases between 2010 and 2020. The reviewers synthesized findings from 15 articles that met the inclusion criteria. The results indicate that communication researchers should be more attentive to the emotional dimension of patient engagement in healthcare communication and that more empirical studies are needed to evaluate the relationship between health literacy and patient engagement among immigrants. Practical implications and recommendations for future research are discussed.

Cultural adaptations to a telephone genetic counseling protocol and booklet for Latina breast cancer survivors at risk for hereditary breast and ovarian cancer

Telephone genetic counseling (TGC) is accepted as standard clinical care for people seeking hereditary cancer risk assessment. TGC has been shown to be non-inferior to in-person genetic counseling, but trials have been conducted with a predominantly highly educated, non-Hispanic White population. This article describes the process of culturally adapting a TGC protocol and visual aid booklet for Spanish-preferring Latina breast cancer survivors at risk for hereditary breast and ovarian cancers. The adaptation process included two phases. Phase 1 involved a review of the literature and recommendations from an expert team including community partners. Phase 2 included interviews and a pilot with the target population (n = 14) to collect feedback about the adapted protocol and booklet following steps from the Learner Verification and Revision Framework. We describe the adaptation process and report the main adaptations following the Framework for Reporting Adaptations and Modifications to Evidence-based Interventions (FRAME). Adaptations in Phase 1 were responsive to the target population needs and characteristics (e.g., delivered in Spanish at an appropriate health literacy level, addressing knowledge gaps, targeting cultural values). Phase 2 interviews were crucial to refine details (e.g., selecting words) and to add components to address GCT barriers (e.g., saliva sample video). Cultural adaptations to evidence-based TGC protocols can increase the fit and quality of care for historically underserved populations. As TGC visits become routine in clinical care, it is crucial to consider the needs of diverse communities to adequately promote equity and justice in cancer care.

Development of a web-based, theory-guided narrative intervention for women at elevated risk for breast cancer

OBJECTIVE

To describe the development of a web-based, theory-guided narrative intervention that replaces conventional pre-test genetic counseling for women at elevated breast cancer risk.

METHODS

We used an iterative process that was guided by health behavior theory and feedback from multiple stakeholder groups including: 1) content input from genetic experts; 2) study team input; 3) review of video storyboards, video example, study logo, recruitment materials, post-test patient preference counseling survey, and additional study surveys; 4) video series development; and 5) intervention review and finalization of study-related materials.

RESULTS

The intervention is patient-centered providing convenience and an opportunity for an individual's preferences for post-test counseling delivery. The intervention's efficacy is being determined in a randomized controlled trial compared to conventional genetic counseling for adherence to recommended guidelines and changes in knowledge, perception of breast cancer risk, breast cancer-specific worry, and satisfaction with counseling.

CONCLUSION

If efficacious, the intervention may improve the delivery of the genetic testing and counseling process, inform best practices, and reduce the genetic counseling workforce burden.

PRACTICE IMPLICATIONS

The developed intervention has the potential to improve the genetic testing and counseling experience for women at elevated risk for breast cancer, inform best practices, and reduce genetic counseling workforce burden.

Informational needs of individuals from families harboring BRCA pathogenic variants: A systematic review and content analysis

PURPOSE

Personalized information is paramount to patient-centered communication and decision-making regarding risk management in hereditary cancer syndromes. This systematic review identified information needs of individuals from families harboring BRCA pathogenic variants and compared findings based on gender (women vs men) and clinical characteristics (patients with cancer vs previvors and BRCA heterozygotes vs untested relatives).

METHODS

We screened 8115 studies identified from databases and citation searching. The quality of selected studies was assessed using the Mixed Methods Appraisal Tool. Narrative synthesis was conducted based on content analysis.

RESULTS

From 18 selected studies including 1063 individuals, we identified 9 categories of information needs. Risk of bias in the selected studies was moderate. Men, untested relatives, and racial and ethnic minorities were underrepresented. Frequently required information was personalized cancer risk and risk-reducing strategies, including decision-making, family implications of hereditary cancers, psychological issues, and cascade testing. Subgroup analyses showed that information needs depended on gender, personal cancer history, and cascade testing in relatives.

CONCLUSION

We identified comprehensive and detailed informational needs of individuals from families harboring BRCA pathogenic variants and gaps in international guidelines. Needs for personalized information varied based on gender, health, and genetic testing status. Findings of this study have implications for genetic counseling, tailoring educational materials, and personalizing interventions.

Women's thoughts on receiving and sharing genetic information: Considerations for genetic counseling

Indications for genetic testing for inherited cancer syndromes are expanding both in the academic and the community setting. However, only a fraction of individuals who are candidates for testing pursue this option. Therefore, it is important to understand those factors that impact the uptake of genetic testing in individuals affected and unaffected with cancer. A successful translation of genomic risk stratification into clinical care will require that providers of this information are aware of the attitudes, perceived risks and benefits, and concerns of individuals who will be considering testing. The purpose of this study was to assess beliefs, attitudes and preferences for genetic risk information, by personal characteristics of women affected and unaffected by breast cancer enrolled in the Breast Cancer Family Registry Cohort. Data for this analysis came from eight survey questions, which asked participants (N = 9,048, 100% female) about their opinions regarding genetic information. Women reported that conveying the accuracy of the test was important and were interested in information related to personal level of risk, finding out about diseases that could be treated, and information that could be helpful to their families. Young women were most interested in how their own health needs might be impacted by genetic test results, while older women were more interested in how genetic information would benefit other members of the family. Interest in how the genetic test was performed was highest among Asian and Hispanic women. Women affected with breast cancer were more likely to report feeling sad about possibly passing down a breast cancer gene, while unaffected women were more uncertain about their future risk of cancer. The variety of informational needs identified has implications for how genetic counselors can tailor communication to individuals considering genetic testing.

Disparities in cancer genetics care by race/ethnicity among pan-cancer patients with pathogenic germline variants

BACKGROUND

Germline risk assessment is increasing as part of cancer care; however, disparities in subsequent genetic counseling are unknown.

METHODS

Pan-cancer patients were prospectively consented to tumor-normal sequencing via custom next generation sequencing panel (Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets) inclusive of germline analysis of ≥76 genes from January 2015 through December 2019 (97.5% research nonbillable) with protocol for genetics referral. Rates of pathogenic/likely pathogenic germline variants (PVs) and downstream counseling were compared across ancestry groups (mutually exclusive groups based on self-reported race/ethnicity and Ashkenazi Jewish [AJ] heritage) using nonparametric tests and multivariable logistic regression models.

RESULTS

Among 15,775 patients (59.6%, non-Hispanic [NH]-White; 15.7%, AJ; 20.5%, non-White [6.9%, Asian; 6.8%, Black/African American (AA); 6.7%, Hispanic; 0.1%, Other], and 4.2%, unknown), 2663 (17%) had a PV. Non-White patients had a lower PV rate (n = 433, 13.4%) compared to NH-Whites (n = 1451, 15.4%) and AJ patients (n = 683, 27.6%), p < .01, with differences in mostly moderate and low/recessive/uncertain penetrance variants. Among 2239 patients with new PV, 1652 (73.8%) completed recommended genetic counseling. Non-White patients had lower rates of genetic counseling (67.7%) than NH-White (73.7%) and AJ patients (78.8%), p < .01, with lower rates occurring in Black/AA (63%) compared to NH-White patients, even after adjustment for confounders (odds ratio, 0.60; 95% confidence interval, 0.37-0.97; p = .036). Non-White, particularly Black/AA and Asian, probands had a trend toward lower rates and numbers of at-risk family members being seen for counseling/genetic testing.

CONCLUSIONS

Despite minimizing barriers to genetic testing, non-White patients were less likely to receive recommended cancer genetics follow-up, with potential implications for oncologic care, cancer risk reduction, and at-risk family members.

LAY SUMMARY

Genetic testing is becoming an important part of cancer care, and we wanted to see if genetics care was different between individuals of different backgrounds. We studied 15,775 diverse patients with cancer who had genetic testing using a test called MSK-IMPACT that was covered by research funding. Clinically important genetic findings were high in all groups. However, Black patients were less likely to get recommended counseling compared to White patients. Even after removing many roadblocks, non-White and especially Black patients were less likely to get recommended genetics care, which may affect their cancer treatments and families.

Examining the role of language competency in genetic testing awareness among adults in the United States

English language competency, as a component of health literacy, is associated with increased awareness and uptake of health-related genetic testing. The relationship between language competency and genetic testing awareness has not yet been explored in the wider U.S. population yet has significant implications for the practice of genetic counselors and in the promotion of genomic medicine for public health. We analyzed data from the 2017 Health Information National Trends Survey 5 Cycle 1 using weighted logistic regression to model the relationship between self-reported English competency, genetic testing awareness, and race and explore adjusted odds ratios and average marginal effects for levels of English competency. Compared to respondents with high English competency, the probability of genetic testing awareness was 20 percentage points lower for White participants reporting moderate English competency (p = .029) and 37 percentage points lower for non-White participants reporting low English competency (p < .001). Future research is needed to understand the mechanisms through which English competency affects awareness and uptake of genetic testing in the United States and to develop strategies to overcome language barriers for the practice of genetic counselors and the implementation of genetics services.

Assessing Vietnamese American patient perspectives on population genetic testing in primary care: A community-engaged approach

Achieving health equity in precision medicine remains a critical challenge because of the continued underrepresentation of non-white populations in research and barriers to genetic services. The goal of this study was to explore Vietnamese American (VA) participant views toward incorporating genetics in routine healthcare to better serve the local VA community within an integrated health system offering primary care-based population genetic testing to adults for conditions that could be prevented or mitigated when detected early. We conducted semi-structured interviews from August–September 2021, with 22 individuals receiving primary care who self-identified as Vietnamese or VA, and employed rapid qualitative analysis (RQA) to identify key concepts. Community research team members participated in study design, data collection, RQA, and reporting. Findings from the interviews revealed that several participant perceived challenges to genetic testing, which included lack of information, fear of results impact, cost, and privacy concerns. Participants suggested various ways to overcome some of these barriers, such as decreasing the cost of testing, receiving information from a trusted physician, using preferred education strategies in the community, and having convenient access to testing. Study participants also shared a variety of trusted sources they would seek out for advice on genetic testing. This study with VAs identified barriers, facilitators, and messengers to offering genetic testing in a local healthcare context and demonstrated how community-engaged research coupled with RQA is a promising approach for healthcare institutions as they identify needs and tailor strategies for implementing population genetic screening programs in local ethnic communities.

Adapting a Theoretically-Based intervention for underserved clinical populations at increased risk for hereditary Cancer: Lessons learned from the BRCA-Gist experience

•

The use of GCT in underserved diverse populations is suboptimal.

•

Translational genomics research has been conducted with mostly NHW.

•

Adapting EBIs can enhance the reach of EBI to underserved diverse populations.

•

This paper describes the adaptation BRCA Gist, for at-risk Blacks and Latinas.

•

Findings illustrate the need to integrate fidelity and adaptation considerations.

Background

Minorities at increased risk for Hereditary Breast and Ovarian Cancer (HBOC) frequently have low awareness and use of genetic counseling and testing (GCT). Making sure that evidence-based interventions (EBIs) reach minorities is key to reduce disparities. BRCA-Gist is a theory-informed EBI that has been proven to be efficacious in mostly non-Hispanic White non-clinical populations. We conducted formative work to inform adaptations of BRCA-Gist for use in clinical settings with at-risk diverse women.

Methods

Genetic counselors (n = 20) were recruited nationally; at-risk Latinas and Blacks (n = 21) were recruited in Washington DC and Virginia. They completed the BRCA-Gist EBI between April 2018 – September 2019. Participants completed an acceptability scale and an interview to provide suggestions about implementation adaptations. T-tests for independent samples compared acceptability between at-risk women and genetic counselors. The Consensual Qualitative Research Framework was used to code adaptation suggestions. Suggested adaptations were discussed by a multidisciplinary team to integrate fidelity and adaptation considerations.

Results

At-risk women had a significantly higher acceptability (M = 4.17, SD = 0.47 vs. M = 3.24, SD = 0.64; p = 0.000; scale 1–5) and satisfaction scores (M = 8.3, SD = 1.3 vs. M = 4.2, SD = 2.0; p = 0.000; scale 1–10) than genetic counselors. Genetic counselors and at-risk women suggested contextual (e.g. format) and content (e.g. shortening) adaptations to enhance the fit of BRCA-Gist for diverse clinical populations.

Conclusions

Findings illustrate the process of integrating fidelity and adaptation considerations to ensure that EBIs retain their core components while enhancing the fit to minoritized clinical populations. Future studies will test the efficacy of the adapted BRCA-Gist in a Randomized Controlled Trial.

Pilot study of a culturally sensitive intervention to promote genetic counseling for breast cancer risk

BACKGROUND

Despite the benefits of genetic counseling and testing, uptake of cancer genetic services is generally low and Black/African American (Black) women are substantially less likely to receive genetic services than non-Hispanic White women. Our team developed a culturally sensitive, narrative decision aid video to promote uptake of genetic counseling among Black women at risk for a hereditary breast cancer syndrome that can be incorporated in conjunction with population-based cancer risk assessment in a clinical setting. We report here a pilot study to demonstrate changes in intention to access genetic counseling and intervention satisfaction.

METHODS

Black women who were personally unaffected by breast cancer and were recommended for genetic counseling based on family history screening in a mammography center were recruited at the time of the mammogram. A prospective, pre-post survey study design, guided by theoretical constructs, was used to evaluate baseline and immediate post-intervention psychosocial factors, including intention to participate in genetic counseling and intervention satisfaction.

RESULTS

Pilot recruitment goals were met (n = 30). Pre-intervention, 50% of participants indicated that they were extremely likely to make a genetic counseling appointment, compared with 70% post-intervention (p = 0.05). After watching the intervention, 50% of participants indicated that the video changed their mind regarding genetic counseling.

CONCLUSIONS

This study demonstrated cultural satisfaction with a decision aid intervention designed to motivate Black women with hereditary breast cancer risk to attend a genetic counseling appointment. Our study showed that intention may be a specific and key construct to target in interventions designed to support decision-making about genetic services. Study results informed the design of a subsequent large scale, randomized implementation study.

Laboratory-related outcomes from integrating an accessible delivery model for hereditary cancer risk assessment and genetic testing in populations with barriers to access

PURPOSE

This study aimed to evaluate the laboratory-related outcomes of participants who were offered genomic testing based on cancer family history risk assessment tools.

METHODS

Patients from clinics that serve populations with access barriers, who are screened at risk for a hereditary cancer syndrome based on adapted family history collection tools (the Breast Cancer Genetics Referral Screening Tool and PREMM₅), were offered exome-based panel testing for cancer risk and medically actionable secondary findings. We used descriptive statistics, electronic health record review, and inferential statistics to explore participant characteristics and results, consultations and actions related to pathogenic/likely pathogenic variants identified, and variables predicting category of findings, respectively.

RESULTS

Of all the participants, 87% successfully returned a saliva kit. Overall, 5% had a pathogenic/likely pathogenic cancer risk variant and 1% had a secondary finding. Almost all (14/15, 93%) participants completed recommended consultations with nongenetics providers after an average of 17 months. The recommended actions (eg, breast magnetic resonance imaging) were completed by 17 of 25 participants. Participant personal history of cancer and PREMM₅ score were each associated with the category of findings (history and colon cancer finding, Fisher's exact P = .02; history and breast cancer finding, Fisher's exact P = .01; PREMM₅^TM score; and colon cancer finding, Fisher's exact P < .001).

CONCLUSION

This accessible model of hereditary cancer risk assessment and genetic testing yielded results that were often acted upon by patients and physicians.

Development and evaluation of an exome sequencing training course for medical interpreters

Aim: As genomic medicine reaches more diverse populations, there is an increased need for healthcare interpreters who understand and can effectively interpret genomics concepts. Methods: We designed a course for healthcare interpreters on exome sequencing to enhance their preparedness for genomic results disclosure appointments in the Cancer Health Assessments Reaching Many (CHARM) study and beyond. The course was evaluated via pre/post surveys and qualitative interviews. Results: 23 interpreters completed the course; 87% rated it as excellent/very good. Improved pre/post confidence interpreting for genetics appointments was statistically significant; pre/post knowledge was not. Interviews highlighted the need for more discussion time. Conclusion: While the course increased confidence interpreting for exome sequencing results appointments, suggested modifications could enhance knowledge and retention of key concepts.

Understanding the Information Needs of Patients With Ovarian Cancer Regarding Genetic Testing to Inform Intervention Design: Interview Study

Background

Experts in gynecological cancer care recommend that all patients with invasive or high-grade ovarian cancer (OC) undergo genetic testing. However, even patients who intend to take or have taken genetic tests have many unaddressed information needs regarding genetic testing. Existing genetic counseling falls short of adequately addressing this challenge.

Objective

This study aims to investigate the genetic testing–related information needs of patients with OC to inform the design of interactive technology-based interventions that can enhance communication of genetic testing information to patients.

Methods

We interviewed 20 patients with OC who had taken genetic tests and gathered genetic testing–related messages from an active OC web-based community. The interview transcripts and web-based community messages were analyzed using the qualitative content analysis method.

Results

Data analyses produced a comprehensive taxonomy of the genetic testing–related information needs of patients with OC, which included five major topic clusters: knowledge of genetic testing as a medical test, genetic testing process, genetic testing implications for patients, implications for family members, and medical terminology. Findings indicated that patients wanted to receive information that was relevant, understandable, concise, usable, appropriate, sympathetic, and available when needed. They also preferred various channels to receive information, including internet-based technologies, print, and conversations with health care providers.

Conclusions

Patients with OC need a range of information to address the uncertainties and challenges that they encounter while taking genetic tests. Their preferences for channels to receive information vary widely. A multichannel information delivery solution that combines both provider-led and peer-to-peer education models is needed to supplement existing genetic counseling to effectively meet the genetic testing–related information needs of patients with OC.

Health equality, race and pharmacogenomics

Pharmacogenomics is increasingly moving into mainstream clinical practice. Careful consideration must be paid to inclusion of diverse populations in research, translation and implementation, in the historical and social context of population stratification, to ensure that this leads to improvements in healthcare for all rather than increased health disparities. This review takes a broad and critical approach to the current role of diversity in pharmacogenomics and addresses potential pitfalls in order to raise awareness for prescribers. It also emphasizes evidence gaps and suggests approaches that may minimize negative consequences and promote health equality.

Healthcare Predictors of Information Dissemination About Genetic Risks

Objectives

Despite the benefits of genetic counseling and testing (GCT), utilization is particularly low among African American (AA) women who exhibit breast cancer features that are common in BRCA-associated cancer. Underutilization is especially problematic for AA women who are more likely to die from breast cancer than women from any other race or ethnicity. Due to medical mistrust, fear, and stigma that can be associated with genetic services among racial/ethnic minorities, reliance on trusted social networks may be an impactful strategy to increase dissemination of knowledge about hereditary cancer risk. Informed by the social cognitive theory, the purpose of this study is to determine: 1) which AA patients diagnosed with breast cancer and with identified hereditary risk are sharing information about hereditary risk with their networks; 2) the nature of the information dissemination; and 3) if personal GCT experiences is associated with dissemination of information about hereditary risk.

Methods

Among consented participants (n = 100) that completed an interview administered using a 202-item questionnaire consisting of open- and closed-ended questions, 62 patients were identified to be at higher risk for breast cancer. Descriptive statistics, bivariable chi-square, Pearson’s exact tests, and regression analyses were conducted to examine differences in characteristics between high-risk participants who disseminated hereditary risk information and participants who did not.

Results

Among high-risk participants, 25 (40%) indicated they had disseminated information about hereditary risk to at least one member in their family/friend network and 37 (60%) had not. Receipt of both provider recommendations and receipt of GCT services was associated with greater odds of disseminating information about hereditary risk with networks, OR = 4.53, 95%CI [1.33, 15.50], p = .02.

Conclusion

Interventions that increase self-efficacy gained through additional personalized knowledge and experience gained through provider recommendations and by undergoing GCT may facilitate information dissemination among social/familial networks.

Precision communication: Physicians' linguistic adaptation to patients' health literacy

Little quantitative research has explored which clinician skills and behaviors facilitate communication. Mutual understanding is especially challenging when patients have limited health literacy (HL). Two strategies hypothesized to improve communication include matching the complexity of language to patients’ HL (“universal tailoring”); or always using simple language (“universal precautions”). Through computational linguistic analysis of 237,126 email exchanges between dyads of 1094 physicians and 4331 English-speaking patients, we assessed matching (concordance/discordance) between physicians’ linguistic complexity and patients’ HL, and classified physicians’ communication strategies. Among low HL patients, discordance was associated with poor understanding (P = 0.046). Physicians’ “universal tailoring” strategy was associated with better understanding for all patients (P = 0.01), while “universal precautions” was not. There was an interaction between concordance and communication strategy (P = 0.021): The combination of dyadic concordance and “universal tailoring” eliminated HL-related disparities. Physicians’ ability to adapt communication to match their patients’ HL promotes shared understanding and equity. The ‘Precision Medicine’ construct should be expanded to include the domain of ‘Precision Communication.’

Defining the Critical Components of Informed Consent for Genetic Testing

Purpose: Informed consent for genetic testing has historically been acquired during pretest genetic counseling, without specific guidance defining which core concepts are required. Methods: The Clinical Genome Resource (ClinGen) Consent and Disclosure Recommendations Workgroup (CADRe) used an expert consensus process to identify the core concepts essential to consent for clinical genetic testing. A literature review identified 77 concepts that are included in informed consent for genetic tests. Twenty-five experts (9 medical geneticists, 8 genetic counselors, and 9 bioethicists) completed two rounds of surveys ranking concepts’ importance to informed consent. Results: The most highly ranked concepts included: (1) genetic testing is voluntary; (2) why is the test recommended and what does it test for?; (3) what results will be returned and to whom?; (4) are there other types of potential results, and what choices exist?; (5) how will the prognosis and management be impacted by results?; (6) what is the potential family impact?; (7) what are the test limitations and next steps?; and (8) potential risk of genetic discrimination and legal protections. Conclusion: Defining the core concepts necessary for informed consent for genetic testing provides a foundation for quality patient care across a variety of healthcare providers and clinical indications.

Perceptions, Beliefs, and Experiences of Asians and Micronesian Islanders on Family Health History Genetic Cancer Screening Community Outreach

Cancer carries stigma, taboos, and shame including, for diverse communities, who can have difficulty understanding and communicating about family health history genetic cancer screening (GCS). The Oregon Health Authority ScreenWise Program reached out to our academic-community research team to explore Asians and Micronesian Islanders (MI) perceptions on public health education outreach on GCS due to having previously only worked with the Latinx community. The purpose of the qualitative description pilot study was to elicit perceptions, beliefs, experiences, and recommendations from Asian and MI community leaders and community members regarding family health history GCS outreach in communities. Twenty Asians (Chinese and Vietnamese) and Micronesian Islanders (Chuukese and Marshallese) were recruited from the US Pacific Northwest. Nineteen participants are immigrants with an average 21.4 and 18.5 years having lived in the USA, respectively. Individual in-depth interviews were conducted using a semi-structured, open-ended interview guide and analyzed using conventional content analysis. Three main transcultural themes were identified: (1) degree of knowing and understanding cancer screening versus family health history GCS, (2) needing culturally relevant outreach messaging on family health history GCS, and (3) communication and decision-making regarding discussing with family and health care providers about cancer screening and GCS. Culturally relevant messaging rather than generic messaging is needed for inclusive outreach. Healthcare providers are encouraged to assess a client's family health history routinely because Asian and MI clients may not understand the information requested, may be hesitant to offer, or unable to provide information about their personal or family history of cancer.

Lay understandings of drug-gene interactions: The right medication, the right dose, at the right time, but what are the right words?

As pharmacogenomic (PGx) testing increases in popularity, lay concepts of drug‐gene interactions set the stage for shared decision making in precision medicine. Few studies explore what recipients of PGx results think is happening in their bodies when a drug‐gene interaction is discovered. To characterize biobank participants’ understanding of PGx research results, we conducted a focus group study, which took place after PGx variants conferring increased risk of dihydropyrimidine dehydrogenase (DPD) deficiency were disclosed to biobank contributors. DPD deficiency confers an increased risk of adverse reaction to commonly used cancer chemotherapeutics. Ten focus groups were conducted, ranging from two to eight participants. Fifty‐four individuals participated in focus groups. A framework approach was used for descriptive and explanatory analysis. Descriptive themes included participants’ efforts to make sense of PGx findings as they related to: (1) health implications, (2) drugs, and (3) genetics. Explanatory analysis supplied a functional framework of how participant word choices can perform different purposes in PGx communication. Results bear three main implications for PGx research‐related disclosure. First, participants’ use of various terms suggest participants generally understanding their PGx results, including how positive PGx results differ from positive disease susceptibility genetic results. Second, PGx disclosure in biobanking can involve participant conflation of drug‐gene interactions with allergies or other types of medical reactions. Third, the functional framework suggests a need to move beyond a deficit model of genetic literacy in PGx communication. Together, findings provide an initial evidence base for supporting bidirectional expert‐recipient PGx results communication.

Design and user experience testing of a polygenic score report: a qualitative study of prospective users

Background

Polygenic scores—which quantify inherited risk by integrating information from many common sites of DNA variation—may enable a tailored approach to clinical medicine. However, alongside considerable enthusiasm, we and others have highlighted a lack of standardized approaches for score disclosure. Here, we review the landscape of polygenic score reporting and describe a generalizable approach for development of a polygenic score disclosure tool for coronary artery disease.

Methods

We assembled a working group of clinicians, geneticists, data visualization specialists, and software developers. The group reviewed existing polygenic score reports and then designed a two-page mock report for coronary artery disease. We then conducted a qualitative user-experience study with this report using an interview guide focused on comprehension, experience, and attitudes. Interviews were transcribed and analyzed for themes identification to inform report revision.

Results

Review of nine existing polygenic score reports from commercial and academic groups demonstrated significant heterogeneity, reinforcing the need for additional efforts to study and standardize score disclosure. Using a newly developed mock score report, we conducted interviews with ten adult individuals (50% females, 70% without prior genetic testing experience, age range 20–70 years) recruited via an online platform. We identified three themes from interviews: (1) visual elements, such as color and simple graphics, enable participants to interpret, relate to, and contextualize their polygenic score, (2) word-based descriptions of risk and polygenic scores presented as percentiles were the best recognized and understood, (3) participants had varying levels of interest in understanding complex genomic information and therefore would benefit from additional resources that can adapt to their individual needs in real time. In response to user feedback, colors used for communicating risk were modified to minimize unintended color associations and odds ratios were removed. All 10 participants expressed interest in receiving a polygenic score report based on their personal genomic information.

Conclusions

Our findings describe a generalizable approach to develop a polygenic score report understandable by potential patients. Although additional studies are needed across a wider spectrum of patient populations, these results are likely to inform ongoing efforts related to polygenic score disclosure within clinical practice.

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.

"Being proactive, not reactive": exploring perceptions of genetic testing among White, Latinx, and Pacific Islander Populations

Genetic testing is becoming an integral part of healthcare, but evidence suggests that both race and ethnicity influence access to and utilization of genetic testing. Given this barrier, data are needed on the perceptions of genetic testing in racial and ethnic minority groups. The purpose of this study was to explore the perceptions of three types of genetic testing (genetic testing for adult-onset conditions, prenatal screening, and newborn screening) in a sample of US participants who identified as White, Pacific Islander, and Latinx (10 dyads from each group for 60 participants total). Data were collected through semi-structured dyadic interviews and assessed using thematic analysis. The major themes were knowledge as empowering, knowledge as stressful, and predictive nature of prenatal testing and newborn screening. Some differences were seen in themes by race and ethnicity. A sense of collective and familial health appeared to be a more important theme for Pacific Islander and Latinx participants compared to White participants. Adult-onset genetic testing was viewed variously across all groups with some noting how it may increase anxiety, particularly if the disease screened for was unable to be prevented with action. All three groups reported on the positives of prenatal testing and newborn screening yet often were confused on the differences between them. This study presents novel perceptions of genetic testing in participants from diverse communities across three types of genetic testing. Genetic healthcare providers should incorporate participants' perceptions, values, and beliefs into their counseling delivery as a way to engage with diverse communities.

Relationship between genetic knowledge and familial communication of CRC risk and intent to communicate CRCP genetic information: insights from FamilyTalk eMERGE III

Successful translation of genetic information into patient-centered care and improved outcomes depends, at least in part, on patients' genetic knowledge. Although genetic knowledge is believed to be an important facilitator of familial communication of genetic risk information, empirical evidence of this association is lacking. We examined whether genetic knowledge was related to frequency of current familial communication about colorectal cancer and polyp (CRCP) risk, and future intention to share CRCP-related genomic test results with family members in a clinical sample of patients. We recruited 189 patients eligible for clinical CRCP sequencing to the eMERGE III FamilyTalk randomized controlled trial and surveyed them about genetic knowledge and familial communication at baseline. Participants were primarily Caucasian, 47% male, average age of 68 years, mostly well educated, and with high-income levels. Genetic knowledge was positively associated with future-intended familial communication of genetic information (odds ratio = 1.11, 95% confidence interval: 1.02-1.23), but not associated with current communication of CRC risk (β = 0.01, p = .58). Greater current communication of CRC risk was associated with better family functioning (β = 0.04, p = 8.2e-5). Participants' genetic knowledge in this study was minimally associated with their intended familial communication of genetic information. Although participants have good intentions of communication, family-level factors may hinder actual follow through of these intentions. Continued focus on improving proband's genetic knowledge coupled with interventions to overcome family-level barriers to communication may be needed to improve familial communication rates.

Multiple approaches to enhancing cancer communication in the next decade: translating research into practice and policy

Communicating risk and other health information in a clear, understandable, and actionable manner is critical for the prevention and control of cancer, as well as the care of affected individuals and their family members. However, the swift pace of development in communication technologies has dramatically changed the health communication landscape. This digital era presents new opportunities and challenges for cancer communication research and its impact on practice and policy. In this article, we examine the science of health communication focused on cancer and highlight important areas of research for the coming decade. Specifically, we discuss three domains in which cancer communication may occur: (a) among patients and their healthcare providers; (b) within and among families and social networks; and (c) across communities, populations, and the public more broadly. We underscore findings from the prior decade of cancer communication research, provide illustrative examples of future directions for cancer communication science, and conclude with considerations for diverse populations. Health informatics studies will be necessary to fully understand the growing and complex communication settings related to cancer: such works have the potential to change the face of information exchanges about cancer and elevate our collective discourse about this area as newer clinical and public health priorities emerge. Researchers from a wide array of specialties are interested in examining and improving cancer communication. These interdisciplinary perspectives can rapidly advance and help translate findings of cancer communication in the field of behavioral medicine.

Genetic counseling and testing for Asian Americans: a systematic review

PURPOSE

Asian Americans have been understudied in the literature on genetic and genomic services. The current study systematically identified, evaluated, and summarized findings from relevant qualitative and quantitative studies on genetic health care for Asian Americans.

METHODS

A search of five databases (1990 to 2018) returned 8,522 unique records. After removing duplicates, abstract/title screening, and full text review, 47 studies met inclusion criteria. Data from quantitative studies were converted into "qualitized data" and pooled together with thematic data from qualitative studies to produce a set of integrated findings.

RESULTS

Synthesis of results revealed that (1) Asian Americans are under-referred but have high uptake for genetic services, (2) linguistic/communication challenges were common and Asian Americans expected more directive genetic counseling, and (3) Asian Americans' family members were involved in testing decisions, but communication of results and risk information to family members was lower than other racial groups.

CONCLUSION

This study identified multiple barriers to genetic counseling, testing, and care for Asian Americans, as well as gaps in the research literature. By focusing on these barriers and filling these gaps, clinical genetic approaches can be tailored to meet the needs of diverse patient groups, particularly those of Asian descent.

Adapting genetic counseling operations amidst the COVID-19 pandemic

The COVID-19 pandemic caused significant disruptions to the delivery of genetic counseling services and clinical operations. Understanding how these pivots in practice affected patient care across both a county hospital system and academic medical center can help provide models of clinical operations for other genetic counselors. Programmatic data were analyzed between March 18, 2020 and September 18, 2020, including visit completion rates and genetic testing completion outcomes for genetic counseling services during the COVID-19 pandemic. In addition to analyzing the effects on patient care, we provide commentary on technological adaptations that aided our operations, billing practices, onboarding and engaging new and existing staff, and coordination of education and outreach opportunities. Through this work, we highlight barriers encountered and successful adaptations that will influence future clinical practices and may guide other providers in the development of strategies to meet their clinical and operational needs.

Spanish language concordance in genetic counseling sessions in the United States: Counselor experiences and perceptions of its effects on processes and outcomes

Prior research suggests language concordance positively affects physician-patient communication and their relationship, but few studies have investigated language concordance in genetic counseling sessions for Spanish-speaking patients. This study explored Spanish-speaking genetic counselors' experiences and perceptions of the effects of Spanish language concordance on session processes and outcomes using the Reciprocal-Engagement Model (REM) of practice as a conceptual framework. There are 17 REM goals associated with four goal factors. A secondary purpose was to explore whether perceived effects are modified when the genetic counselor identifies as Latinx. Ten Latina and nine non-Latina Spanish-speaking genetic counselors who practice in the U.S. participated in semi-structured phone interviews. Directed content analysis yielded four themes reflecting how spoken language concordance promotes REM goal factors (Understanding and Appreciation, Support and Guidance, Facilitative Decision-Making, and Patient-Centered Education) and individual goals within each factor. Six additional themes also emerged: Patients feel grateful/relieved to have a genetic counselor who communicates directly in Spanish; Challenges are lessened (e.g., no need for an interpreter); Language interacts with other cultural similarities to achieve REM goals; Use of Spanish conveys genetic counselor is 'going above and beyond' for patients; Communicating medical information is difficult even when Spanish proficient; and Genetic counselor still able to achieve REM goals without language concordance. There were no apparent thematic differences between Latina and non-Latina genetic counselors. Results suggest language concordance positively influences relationship building and communication and facilitates achievement of REM goals. Proficiency in more than one language is 'value added' for genetic counseling services and should be encouraged in genetic counseling graduate programs and continuing education opportunities. Future research could assess patient perceptions of genetic counseling sessions in which the genetic counselor and patient use the patient's preferred language.

Metaphors and why these are important in all aspects of genetic counseling

Metaphors appear simple but are fundamental schemata allowing expression and processing of complex emotions and information. They are so embedded in language and thinking that we are often unaware of their impact, despite the crucial role of metaphors in communication, learning and creating meaning from experiences. A deeper understanding of how to recognize and work with client-generated and counselor-generated metaphors has great potential as an addition to the genetic counseling 'tool-box'. Here, we draw on studies from related health and psychotherapy fields to discuss how working purposefully with metaphors may offer a powerful way to enhance communication within a reciprocally engaged client-counselor relationship. Metaphors present ways to explain complex genetic concepts in a personally meaningful form, to gain a deeper understanding of client's experiences and emotions, to assist processing of experiences, emotions, and concepts, and to assist client and counselor to access and reflect on subconscious emotions, self-concept, and motivations. In addition, working with metaphors has been shown to facilitate coping and action. This paper sets the scene for why and how genetic counselors can utilize client-generated and counselor-generated metaphors purposefully in all areas of practice, including enhancing the therapeutic interaction with clients, as well as in supervision, training, cultural competence, and shaping of societal attitudes toward genetics.

Cancer Health Assessments Reaching Many (CHARM): A clinical trial assessing a multimodal cancer genetics services delivery program and its impact on diverse populations

Advances in the application of genomic technologies in clinical care have the potential to increase existing healthcare disparities. Studies have consistently shown that only a fraction of eligible patients with a family history of cancer receive recommended cancer genetic counseling and subsequent genetic testing. Care delivery models using pre-test and post-test counseling are not scalable, which contributes to barriers in accessing genetics services. These barriers are even more pronounced for patients in historically underserved populations. We have designed a multimodal intervention to improve subsequent cancer surveillance, by improving the identification of patients at risk for familial cancer syndromes, reducing barriers to genetic counseling/testing, and increasing patient understanding of complex genetic results. We are evaluating this intervention in two large, integrated healthcare systems that serve diverse patient populations (NCT03426878). The primary outcome is the number of diagnostic (hereditary cancer syndrome) findings. We are examining the clinical and personal utility of streamlined pathways to genetic testing using electronic medical record data, surveys, and qualitative interviews. We will assess downstream care utilization of individuals receiving usual clinical care vs. genetic testing through the study. We will evaluate the impacts of a literacy-focused genetic counseling approach versus usual care genetic counseling on care utilization and participant understanding, satisfaction, and family communication. By recruiting participants belonging to historically underserved populations, this study is uniquely positioned to evaluate the potential of a novel genetics care delivery program to reduce care disparities.

Development and early implementation of an Accessible, Relational, Inclusive and Actionable approach to genetic counseling: The ARIA model

OBJECTIVE

To describe the training and early implementation of the ARIA model of genetic counseling (Accessible, Relational, Inclusive, Actionable).

METHODS

As part of the Cancer Health Assessments Reaching Many (CHARM) study, an interdisciplinary workgroup developed the ARIA curriculum and trained genetic counselors to return exome sequencing results using the ARIA model.

CURRICULUM

The ARIA curriculum includes didactic elements, discussion, readings, role plays, and observations of usual care genetic counseling sessions. The ARIA model provides the skills and strategies needed for genetic counseling to be accessible to all patients, regardless of prior knowledge or literacy level; involves appropriate psychological and social counseling without overwhelming the patient with information; and leaves the patient with clear and actionable next steps.

CONCLUSION

With sufficient training and practice, the ARIA model appears to be feasible, with promise for ensuring that genetic counselors' communication is accessible, relational, inclusive and actionable for the diverse patients participating in genomic medicine.

PRACTICE IMPLICATIONS

ARIA offers a coherent set of principles and strategies for effective communication with patients of all literacy levels and outlines specific techniques to practice and incorporate these skills into routine practice. The ARIA model could be integrated into genetic counseling training programs and practice, making genetic counseling more accessible and meaningful for all patients.

"I think that a brief conversation from their provider can go a very long way": Patient and provider perspectives on barriers and facilitators of genetic testing after ovarian cancer

OBJECTIVE

Identify predisposing, enabling, and reinforcing factors impacting genetic counseling/testing among ovarian cancer patients guided by Green and Kreuter's PRECEDE-PROCEED model.

METHODS

Gynecologic oncology providers (N = 4), genetic counselors (N = 4), and ovarian cancer patients (N = 9) completed semi-structured qualitative interviews exploring participants' knowledge of and experiences with genetic counseling/testing. Interviews were audio recorded, transcribed verbatim, and analyzed using inductive content analysis by two independent raters.

RESULTS

Thematic analysis identified predisposing, enabling, and reinforcing factors impacting referral for and uptake of genetic counseling/testing. Predisposing factors included participant's knowledge, beliefs, and attitudes related to genetic counseling/testing. Both patients and providers also cited that insurance coverage and out-of-pocket cost are major concerns for ovarian cancer patients considering genetic testing. Finally, both patients and providers emphasized that genetic counseling/testing would provide additional information to an ovarian cancer patient. While providers emphasized that genetic testing results were useful for informing a patient's personal treatment plan, patients emphasized that this knowledge would be beneficial for their family members.

CONCLUSION

Barriers to genetic testing for ovarian cancer patients exist at multiple levels, including the patient (e.g., knowledge, attitudes), the provider (e.g., workload, availability of services), the institution (e.g., difficulty with referrals/scheduling), and the healthcare system (e.g., insurance/cost). Interventions aiming to increase genetic testing among ovarian cancer patients will likely need to target multiple levels of influence. Future quantitative studies are needed to replicate these results. This line of work will inform specific multilevel intervention strategies that are adaptable to different practice settings, ultimately improving guideline concordant care.

"This is my boy's health! Talk straight to me!" perspectives on accessible and culturally safe care among Aboriginal and Torres Strait Islander patients of clinical genetics services

BACKGROUND

Aboriginal and Torres Strait Islander people do not enjoy equal access to specialist health services that adequately meet their needs. Clinical genetics services are at the vanguard of realising the health benefits of genomic medicine. As the field continues to expand in clinical utility and implementation, it is critical that Aboriginal and Torres Strait Islander people are able to participate and benefit equally to avoid further widening of the existing health gap. This is the first study to explore barriers to accessing clinical genetics services among Aboriginal and Torres Strait Islander people, which has been acknowledged as a key strategic priority in Australian genomic health policy.

METHODS

A participatory design process engaged a majority-Aboriginal Project Reference Group and Aboriginal End-User Group. 63 semi-structured interviews were conducted with Aboriginal and/or Torres Strait Islander people who had accessed the government-funded clinical genetics service in Western Australia, Queensland or the Northern Territory between 2014 and 2018. The sample included patients, parents and carers. Participants were asked to recount their 'patient journey', from referral through to post-appointment and reflect on their perceptions of genetics and its implications for the health of themselves and their families. Analysis tracked chronological service engagement, followed by an inductive thematic approach.

RESULTS

Barriers to access and engagement were present at each stage of the patient journey. These included challenges in obtaining a referral, long waiting periods, limited genetic literacy, absence of Aboriginal support services, communication challenges and lack of adequate psychosocial support and follow-up after attendance. Participants' overall experiences of attending a genetic health service were varied, with positive perceptions tied closely to a diagnosis being achieved. The experience of (and expectation for) recognition of cultural identity and provision of culturally safe care was low among participants. Unaddressed concerns continued to cause significant distress in some people years after their appointment took place.

CONCLUSIONS

There is significant scope for improving the care provided to Aboriginal and Torres Strait Islander people at clinical genetics services. Immediate attention to minimising logistical barriers, developing relationships with Aboriginal Community Controlled Health Services and providing practical and specific cultural safety training for practitioners is required at the service-level. Our findings strongly support the development of guidelines or policies recognising the collective cultural needs of Aboriginal and Torres Strait Islander people in relation to genomic health care.

Development of a culturally sensitive narrative intervention to promote genetic counseling among African American women at risk for hereditary breast cancer

BACKGROUND

African American women with hereditary breast cancer risk are less likely to undergo genetic counseling and testing compared with non-Hispanic White women. Inequities in the use of precision cancer care are likely to exacerbate racial disparities in cancer outcomes. A culturally sensitive multimedia narrative intervention was developed to motivate African American women at risk for hereditary breast cancer to engage in genetic counseling.

METHODS

Development of the intervention was grounded in the Integrative Model of Behavioral Prediction using a phenomenological, deductive approach and employed multiple qualitative methods for data collection, including 1-on-1 interviews and story circles with members of the target audience to identify salient themes and lived experiences. Focus group testing was then conducted with members of the group of focus, primary care providers, and community stakeholders.

RESULTS

Six themes that mapped to the theoretical model were identified. Lived experiences were abstracted from story circle data to create a narrative storyline. Educational content and motivational messaging derived from the 6 themes were embedded into the script. Focus group testing with stakeholder groups was used to refine the intervention. Testing of the final multimedia narrative with focus groups indicated that the intervention was culturally sensitive and authentic, and the messaging was effective.

CONCLUSIONS

Multiple qualitative data collection methods and a robust theoretical framework of health behavior were key elements for this study to develop a culturally sensitive, narrative intervention that reflects lived experiences and motivates underserved African American women with hereditary breast cancer risk to engage in genetic counseling. This strategy can be applied to mitigate racial inequities in the use of other genomic approaches for personalizing cancer care.

"Is that something that should concern me?": a qualitative exploration of parent understanding of their child's genomic test results

Genetic counselors are trained to deliver complicated genomic test results to parents of pediatric patients. However, there is limited knowledge on how parents perceive this information and what they understand about the results. This research aims to qualitatively explore parents’ experiences receiving genomic test results for their children. As part of formative research for the NYCKidSeq Study, we recruited a purposive sample of parents of 22 children stratified by child race/ethnicity and test result classification (positive, uncertain, or negative) and conducted in-depth interviews using a semi-structured guide. Analysis was conducted using grounded theory’s constant comparative method across cases and themes. Parents described different elements of understanding: genetics knowledge; significance and meaning of positive, uncertain, or negative results; and implications for the health of their child and family. Parents reported challenges understanding technical details and significance of their child’s results but gladly allowed their providers to be custodians of this information. However, of the different elements of understanding described, parents cared most deeply about being able to understand implications for their child’s and family’s health. These findings suggest that a counseling approach that primarily addresses parents’ desire to understand how to best care for their child and family may be more appropriate than an information-heavy approach focused on technical details. Further research is warranted to confirm these findings in larger parent cohorts and to explore ways genetic counseling can support parents’ preferences without sacrificing important components of parent understanding and overall satisfaction with their experiences with genomic medicine.

A review and definition of 'usual care' in genetic counseling trials to standardize use in research

The descriptor 'usual care' refers to standard or routine care. Yet, no formal definition exists. The need to define what constitutes usual care arises in clinical research. Often one arm in a trial represents usual care in comparison with a novel intervention. Accordingly, usual care in genetic counseling research appears predominantly in randomized controlled trials. Recent standards for reporting genetic counseling research call for standardization, but do not address usual care. We (1) inventoried all seven studies in the Clinical Sequencing Evidence-Generating Consortium (CSER) about how genetic counseling was conceptualized, conducted, and whether a usual care arm was involved; (2) conducted a review of published randomized control trials in genetic counseling, comparing how researchers describe usual care groups; and (3) reviewed existing professionally endorsed definitions and practice descriptions of genetic counseling. We found wide variation in the content and delivery of usual care. Descriptions frequently detailed the content of usual care, most often noting assessment of genetic risk factors, collecting family histories, and offering testing. A minority included addressing psychological concerns or the risks versus benefits of testing. Descriptions of how care was delivered were vague except for mode and type of clinician, which varied. This significant variation, beyond differences expected among subspecialties, reduces the validity and generalizability of genetic counseling research. Ideally, research reflects clinical practice so that evidence generated can be used to improve clinical outcomes. To address this objective, we propose a definition of usual care in genetic counseling research that merges common elements from the National Society of Genetic Counselors' practice definition, the Reciprocal Engagement Model, and the Accreditation Council for Genetic Counselors' practice-based competencies. Promoting consistent execution of usual care in the design of genetic counseling trials can lead to more consistency in representing clinical care and facilitate the generation of evidence to improve it.

Recommendations for designing genetic test reports to be understood by patients and non-specialists

Patients and non-specialist healthcare professionals are increasingly expected to understand and interpret the results of genetic or genomic testing. These results are currently reported using a variety of templates, containing different amounts, levels, and layouts of information. We set out to establish a set of recommendations for communicating genetic test results to non-expert readers. We employed a qualitative-descriptive study design with user-centred design principles, including a mixture of in-person semi-structured interviews and online questionnaires with patients, healthcare professionals and the general public. The resulting recommendations and example template include providing at-a-glance comprehension of what the test results mean for the patient; suggested next steps; and details of further information and support. Separation and inclusion of technical methodological details enhances non-specialists' understanding, while retaining important information for specialists and the patients' records. The recommendations address the high-level needs of patients and their non-specialist clinicians when receiving genetic test results. These recommendations provide a solid foundation for the major content and structure of reports, and we recommend further engagement with patients and clinicians to tailor reports to specific types of test and results.

The importance of personalismo: Navigating obstacles in recruitment strategies for Spanish speakers in marginalized communities

Recruitment obstacles with Spanish-speaking individuals and members of marginalized communities have been documented in the literature in narrative form, but quantitative data on effective strategies are limited. Within our research protocol assessing the impact of a storytelling intervention on knowledge and uptake of cell-free DNA (cfDNA) aneuploidy screening, three different recruitment strategies were trialed and enrollment rates were compared. Throughout the study, field notes were collected from observations in recruitment efforts. We demonstrate the effectiveness of language-concordant, personal interactions, and culturally tailored materials for recruitment of Spanish-speaking participants into genomic research studies. We also offer commentary on the experience of the researchers that provides insights to inform recruitment methods for marginalized communities.

A road map for the future: An exploration of attitudes, perceptions, and beliefs among African Americans to tailor health promotion of cancer-related genetic counseling and testing

African Americans (AA), the second largest racial/ethnic minority group in the United States (US), carry the largest mortality burden of cancer compared with other racial/ethnic groups (Cancer Facts & Figures for African Americans, 2019-2021, American Cancer Society).One solution to address this disparity is through cancer-related genetic counseling and testing (CGT). Although CGT is utilized among the general population, it remains underutilized among AA populations. Community-engaged and community-driven health promotion programs within faith-based organizations (FBOs) have been successfully implemented and delivered among AA populations (Israel et al., American Journal of Public Health, 100, 2010, 2094). FBOs are well positioned for cancer-related health promotion and equipped as conduits of health education and information distribution for cancer prevention. In the present pilot study, a community-based participatory approach (CBPR) was used to collect exploratory data on attitudes, perceptions, and beliefs toward CGT and uptake among an AA sample in the Midwest. Focus groups were conducted in two churches where respondents (N=34) answered a pre-focus group survey prior to a discussion. Respondents were largely unaware of CGT and thought of testing as primarily for ancestral discovery and not for an inheritable disease. Themes identified through qualitative analysis included emotional experiences with cancer; perception of cancer risk; different pictures of genetic testing; other things to worry about; trust in the healthcare system/faith in God and the healthcare system; and ideas and insights regarding promotion of CGT. These primary themes showed participants' perceptions of CGT were shaped by their experiences with cancer, faith, faith communities/FBOs, and cost and access to CGT. Overall, participants within these organizations had positive perceptions about the church as a conduit of genetic testing information but had mixed opinions about the rationale for completing CGT. These findings have implications for genetic counselors, medical providers, and health promotion personnel as to how AA faith populations view CGT and the utility of FBOs as promoters of CGT information.
