The motivation and process for developing a consortium-wide time and motion study to estimate resource implications of innovations in the use of genome sequencing to inform patient care.

Costs of implementing genomic testing innovations extend beyond the cost of sequencing, affecting personnel and infrastructure for which little data are available. We developed a time and motion (T&M) study within the Clinical Sequencing Evidence-Generating Research (CSER) consortium to address this gap, and herein describe challenges of conducting T&M studies within a research consortium and the approaches we developed to overcome them. CSER investigators created a subgroup to carry out the T&M study (authors). We describe logistical and administrative challenges associated with resource use data collection across heterogeneous projects conducted in real-world clinical settings, and our solutions for completing this study and harmonizing data across projects. We delineate processes for feasible data collection on workflow, personnel, and resources required to deliver genetic testing innovations in each CSER project. A critical early step involved developing detailed project-specific process flow diagrams of innovation implementation in projects' clinical settings. Analyzing diagrams across sites, we identified common process-step themes, used to organize project-specific data collection and cross-project analysis. Given the heterogeneity of innovations, study design, and workflows, which affect resources required to deliver genetic testing innovations, flexibility was necessary to harmonize data collection. Despite its challenges, this heterogeneity provides rich insights about variation in clinical processes and resource implications for implementing genetic testing innovations.

Assessment of a Peer Physician Coaching Partnership Between a Designated Cancer Center Genetics Service and a Community Cancer Network Hospital.

Background: Patients with cancer seen in rural and underserved areas disproportionately face barriers to access genetic services. Genetic testing is critical to inform treatment decisions, for early detection of another cancer, and to identify at-risk family members who may benefit from screening and prevention. Objective: To examine medical oncologists' genetic testing ordering trends for patients with cancer. Design, Setting, and Participants: This prospective quality improvement study was performed in 2 phases over 6 months between August 1, 2020, and January 31, 2021, at a community network hospital. Phase 1 focused on observation of clinic processes. Phase 2 incorporated peer coaching from cancer genetics experts for medical oncologists at the community network hospital. The follow-up period lasted 9 months. Main Outcomes and Measures: The number of genetic tests ordered was compared between phases. Results: The study included 634 patients (mean [SD] age, 71.0 [10.8] years [range, 39-90 years]; 409 women [64.5%]; 585 White [92.3%]); 353 (55.7%) had breast cancer, 184 (29.0%) had prostate cancer, and 218 (34.4%) had a family history of cancer. Of the 634 patients with cancer, 29 of 415 (7.0%) received genetic testing in phase 1, and 25 of 219 (11.4%) received genetic testing in phase 2. Of the 29 patients who received testing in phase 1, 20 (69.0%) had germline genetic testing; 23 of 25 patients (92.0%) had germline genetic testing in phase 2. Uptake of germline genetic testing increased by 23.0% between phases, but the difference was not statistically significant (P = .06). Uptake of germline genetic testing was highest among patients with pancreatic cancer (4 of 19 [21.1%]) and ovarian cancer (6 of 35 [17.1%]); the National Comprehensive Cancer Network (NCCN) recommends offering genetic testing to all patients with pancreatic cancer and ovarian cancer. Conclusions and Relevance: This study suggests that peer coaching from cancer genetics experts was associated with an increase in ordering of genetic testing by medical oncologists. Efforts made to (1) standardize gathering of personal and family history of cancer, (2) review biomarker data suggestive of a hereditary cancer syndrome, (3) facilitate ordering tumor and/or germline genetic testing every time NCCN criteria are met, (4) encourage data sharing between institutions, and (5) advocate for universal coverage for genetic testing may help realize the benefits associated with precision oncology for patients and their families seeking care at community cancer centers.

Medical interpreter-mediated genetic counseling for Spanish preferring adults at risk for a hereditary cancer syndrome.

The objective of this study was to identify interpretation challenges specific to exome sequencing and errors of potential clinical significance in the context of genetic counseling for adults at risk for a hereditary cancer syndrome. Thirty transcripts of interpreter-mediated telephone results disclosure genetic counseling appointments were coded for errors by bilingual researchers, and the coders applied an overall rating to denote the degree to which the errors interfered with communication overall. Genetic counselors reviewed a subset of errors flagged for potential clinical significance to identify those likely to have clinical impact. Qualitative interviews with 19 interpreters were analyzed to elucidate the challenges they face in interpreting for genetic counseling appointments. Our analysis identified common interpretation errors such as raising the register, omissions, and additions. Further, we found errors specific to genetic counseling concepts and content that appeared to impact the ability of the genetic counselor to accurately assess risk. These errors also may have impacted the patient's ability to understand their results, access appropriate follow-up care, and communicate with family members. Among interpreters' strengths was the use of requests for clarification; in fact, even more use of clarification would have been beneficial in these encounters. Qualitative interviews surfaced challenges stemming from the structure of interpreter work, such as switching from medical and nonmedical interpretations without substantial breaks. Importantly, while errors were frequent, most did not impede communication overall, and most were not likely to impact clinical care. Nevertheless, potentially clinically impactful errors in communication of genetics concepts may contribute to inequitable care for limited English proficient patients and suggest that additional training in genetics and specialization in healthcare may be warranted. In addition, training for genetic counselors and guidance for patients in working effectively with interpreters could enhance interpreters' transmission of complex genetic concepts.

An accessible, relational, inclusive, and actionable (ARIA) model of genetic counseling compared with usual care: Results of a randomized controlled trial.

PURPOSE: Effective approaches to communicate genomic information are needed to ensure equitable care. In a randomized controlled superiority trial, we tested a novel practice model that aims to make genetic counseling inclusive, by making the communication accessible, relational, and actionable (ARIA). METHODS: In total, 696 English- and Spanish-speaking patients aged 18 to 49 years, enriched for individuals from historically underserved backgrounds, were randomized in 1:1 ratio to ARIA or usual care. Primary outcomes were accuracy of recall, communication satisfaction, and perceived understanding. In total, 33 participants completed qualitative interviews. RESULTS: Recall and understanding were high for all participants. ARIA participants scored higher on the relationship scale of communication satisfaction (mean difference = 0.09, 95% CI = <0.01 to 0.17). Moderator analyses of communication satisfaction showed that those with lower health literacy reported less communication difficulty in ARIA and those using medical interpreters reported greater communication ease in ARIA. No significant difference was found on other primary and secondary outcomes. Qualitative data enhanced understanding of how and why ARIA can be effective. CONCLUSION: This study provides evidence that a genetic counseling intervention that focuses on specific communication skills to enhance relationship-building, patient engagement, and comprehension can be effective with all patients and may be especially valuable for patients of lower health literacy and Spanish-speakers who use a medical interpreter.

ORCA, a values-based decision aid for selecting additional findings from genomic sequencing in adults: Efficacy results from a randomized trial.

PURPOSE: Individuals having genomic sequencing can choose to be notified about pathogenic variants in genes unrelated to the testing indication. A decision aid can facilitate weighing one's values before making a choice about these additional results. METHODS: We conducted a randomized trial (N = 231) comparing informed values-choice congruence among adults at risk for a hereditary cancer syndrome who viewed either the Optional Results Choice Aid (ORCA) or web-based additional findings information alone. ORCA is values-focused with a low-literacy design. RESULTS: Individuals in both arms had informed values-choice congruence (75% and 73% in the decision aid and web-based groups, respectively; odds ratio [OR] = 1.10, 95% CI = 0.58-2.08). Most participants had adequate knowledge (79% and 76% in the decision aid and web-based groups, respectively; OR = 1.20, 95% CI = 0.61-2.34), with no significant difference between groups. Most had information-seeking values (97% and 98% in the decision aid and web-based groups, respectively; OR = 0.59, 95% CI = 0.10-3.61) and chose to receive additional findings. CONCLUSION: The ORCA decision aid did not significantly improve informed values-choice congruence over web-based information in this cohort of adults deciding about genomic results. Both web-based approaches may be effective for adults to decide about receiving medically actionable additional results.

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; PREMM5TM 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.

Barriers to family history knowledge and family communication among LGBTQ+ individuals in the context of hereditary cancer risk assessment.

Openness about identity as lesbian, gay, bisexual, transgender, queer, and other sexual orientations and gender identities (LGBTQ+) may cause strain on relationships between family members, which could lead to limited knowledge of cancer family history and reduced communication with family members. As a result, members of the LGBTQ+ community may have more difficulty accessing genetic counseling services for inherited cancer risk. We applied a mixed-methods approach to explore potential barriers to knowledge of cancer family history and family communication among participants of the Cancer Health Assessments Reaching Many (CHARM) study who self-identified as LGBTQ+. We assessed perceptions of family functioning and communication of genetic test results to family members using survey tools and supplemented these data with 20 in-depth interviews to further assess participant perspectives and experiences. LGBTQ+ participants were more likely to report unhealthy family functioning on the survey tool, and some interviewees endorsed that openness about their LGBTQ+ identity led to strained family relationships and reduced communication about their family history of cancer. Overall, this study identified barriers that may be faced by members of the LGBTQ+ community which could limit their ability to access genetic counseling services for inherited cancer risk.

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.
