The incorporation of web-based learning into the dental curriculum has been consistently recommended in the literature on reform in dental education. There has been growing support for web-based learning in dental and dental hygiene education as demonstrated by deans' identifying this as a planned curricular innovation. The purpose of our study was to explore characteristics of e-courses that may serve to increase adoption among dental and dental hygiene faculty members. Eight ninety-minute focus groups (three dental; five dental hygiene) were conducted with dental (n=27) and dental hygiene (n=23) faculty members from six academic institutions. The resulting data were analyzed to identify two overarching themes and associated subthemes with regard to benefits and barriers influencing adoption of e-courses. A working conceptual framework, based on the Diffusion of Innovations, was developed from these themes to understand the characteristics that may influence the rate of adoption of e-courses among dental and dental hygiene faculty members. Analysis of the data revealed four main adoption barriers: 1) low perceived relative advantage to faculty members; 2) low compatibility with current curriculum; 3) high perceived time commitment; and 4) complexity of e-course development. This exploratory assessment identifies leverage points for facilitating the adoption and sustainability of e-courses in dental and dental hygiene education. [ABSTRACT FROM AUTHOR]

Purpose: To guide use of multigene panels for germline genetic testing for patients with cancer., Methods: An ASCO Expert Panel convened to develop recommendations on the basis of a systematic review of guidelines, consensus statements, and studies of germline and somatic genetic testing., Results: Fifty-two guidelines and consensus statements met eligibility criteria for the primary search; 14 studies were identified for Clinical Question 4., Recommendations: Patients should have a family history taken and recorded that includes details of cancers in first- and second-degree relatives and the patient's ethnicity. When more than one gene is relevant based on personal and/or family history, multigene panel testing should be offered. When considering what genes to include in the panel, the minimal panel should include the more strongly recommended genes from Table 1 and may include those less strongly recommended. A broader panel may be ordered when the potential benefits are clearly identified, and the potential harms from uncertain results should be mitigated. Patients who meet criteria for germline genetic testing should be offered germline testing regardless of results from tumor testing. Patients who would not normally be offered germline genetic testing based on personal and/or family history criteria but who have a pathogenic or likely pathogenic variant identified by tumor testing in a gene listed in Table 2 under the outlined circumstances should be offered germline testing.Additional information is available at www.asco.org/molecular-testing-and-biomarkers-guidelines.

Purpose: This study compared Lynch syndrome universal tumor screening (UTS) across multiple health systems (some of which had 2 or more distinct UTS programs) to understand multilevel factors that may affect the successful implementation of complex programs., Methods: Data from 66 stakeholder interviews were used to conduct multivalue coincidence analysis and identify key factors that consistently make a difference in whether UTS programs were implemented and optimized at the system level., Results: The selected coincidence analysis model revealed combinations of conditions that distinguish 4 optimized UTS programs, 10 nonoptimized programs, and 4 systems with no program. Fully optimized UTS programs had both a maintenance champion and a positive inner setting. Two independent paths were unique to nonoptimized programs: (1) positive attitudes and a mixed inner setting or (2) limited planning and engaging among stakeholders. Negative views about UTS evidence or lack of knowledge about UTS led to a lack of planning and engaging, which subsequently prevented program implementation., Conclusion: The model improved our understanding of program implementation in health care systems and informed the creation of a toolkit to guide UTS implementation, optimization, and changes. Our findings and toolkit may serve as a use case to increase the successful implementation of other complex precision health programs., Competing Interests: Conflict of Interest No competing financial interests are reported by any authors in relation to the work described in this paper., (Copyright © 2024 The Authors.

A Variant of Uncertain Significance (VUS) is a difference in the DNA sequence with uncertain consequences for gene function. A VUS in a hereditary cancer gene should not change medical care, yet some patients undergo medical procedures based on their VUS result, highlighting the unmet educational needs among patients and healthcare providers. To address this need, we developed, evaluated, and refined novel educational materials to explain that while VUS results do not change medical care, it remains important to share any personal or family history of cancer with family members given that their personal and family medical history can guide their cancer risk management. We began by reviewing the prior literature and transcripts from interviews with six individuals with a VUS result to identify content and design considerations to incorporate into educational materials. We then gathered feedback to improve materials via a focus group of multidisciplinary experts and multiple rounds of semi-structured interviews with individuals with a VUS result. Themes for how to improve content, visuals, and usefulness were used to refine the materials. In the final round of interviews with an additional 10 individuals with a VUS result, materials were described as relatable, useful, factual, and easy to navigate, and also increased their understanding of cancer gene VUS results.

Genetic counseling (GC) relies on communication to help people understand and adapt to genetic contributions of disease, and there is need for a practical and reliable method of comprehensively documenting GC communication skills without intensive coding. To this end, we created a novel process measure called the Genetic Counseling Skills Checklist (GCSC), utilizing previously validated measures, communication/counseling frameworks, and prior research findings. A multistage iterative process was used to develop, evaluate, and modify the GCSC to improve its clarity, usability, and content validity. To assess interrater reliability, randomly assigned, untrained individuals (i.e., coders) used the GCSC version 3 to code multiple simulated GC sessions. Average measures intraclass correlation coefficients (ICCs) were calculated for each of the 8 GCSC process categories using one-way, random effects models. After relatively minor modifications to the GCSC, two pairs of experienced coders used GCSC version 4 to independently code additional GC sessions and Cohen's Kappa coefficients (κ) were calculated to assess interrater reliability for each process category. The GCSC contains five to eight items within each category and demonstrates good content validity given its ability to capture nearly all GC skills that genetic counselors reported using in a prior qualitative study. Interrater reliability of GCSC version 3 among coders with limited experience was moderate or good for 6 out of the 8 process categories as evidenced by ICCs ranging from 0.55 to 0.86. Average interrater reliability of GCSC version 4 among one pair of experienced coders was strong for all eight process categories (κ ranging from 0.82 to 0.94); among the second pair of experienced coders scores were strong for six categories (κ ranging from 0.80 to 0.87) and moderate for two categories (κ of 0.77 and 0.78). The results suggest the need for training and experience to assure adequate interrater reliability across GCSC coders. Future work is needed to create a formalized training program for coders, complete a larger study to further validate the measure, and use the GCSC to document variability in skills used across providers and sessions., (© 2023 National Society of Genetic Counselors.)

Pharmacogenetic testing could reduce the time to identify a safe and effective medication for depression; however, it is underutilized in practice. Major depression constitutes the most common mental disorder in the US, and while antidepressant therapy can help, the current trial -and error approach can require patients to endure multiple medication trials before finding one that is effective. Tailoring the fit of pharmacogenetic testing with prescribers' needs across a variety of settings could help to establish a generalizable value proposition to improve likelihood of adoption. We conducted a study to explore the value proposition for health systems using pharmacogenetic testing for mental health medications through prescribers' real-world experiences using implementation science concepts and systematic interviews with prescribers and administrators from four health care systems. To identify a value proposition, we organized the themes according to the Triple Aim framework, a leading framework for health care policy which asserts that high-value care should focus on three key metrics: (1) better health care quality and (2) population-level outcomes with (3) reduced per capita costs. Primary care providers whom we interviewed said that they value pharmacogenetic testing because it would provide more information about medications that they can prescribe, expanding their ability to identify medications that best-fit patients and reducing their reliance on referrals to specialists; they said that this capacity would help meet patients' needs for access to mental health care through primary care. At the same time, prescribers expressed differing views about how pharmacogenetic testing can help with quality of care and whether their views about out-of-pocket cost would prevent them from offering it. Thus, implementation should focus on integrating pharmacogenetic testing into primary care and using strategies to support prescribers' interactions with patients., (© 2024 The Author(s).

Introduction: In over 50 years since the genetic counseling (GC) profession began, a systematic study of GC communication skills and patient-reported outcomes in actual sessions across multiple clinical specialties has never been conducted. To optimize GC quality and improve efficiency of care, the field must first be able to comprehensively measure GC skills and determine which skills are most critical to achieving positive patient experiences and outcomes. This study aims to characterise GC communication skills using a novel and pragmatic measure and link variations in communication skills to patient-reported outcomes, across clinical specialties and with patients from diverse backgrounds in the USA. Our community-engagement and provider-engagement approach is crucial to develop recommendations for quality, culturally informed GC care, which are greatly needed to improve GC practice., Methods and Analysis: A mixed methods, sequential explanatory design will be used to collect and analyze: audio-recorded GC sessions in cancer, cardiac, and prenatal/reproductive genetic indications; pre-visit and post-visit quantitative surveys capturing patient experiences and outcomes and post-visit qualitative interview data. A novel, practical checklist will measure GC communication skills. Coincidence analysis will identify patterns of GC skills that are consistent with high scores on patient-reported measures. Two-level, multilevel models will be used to evaluate how GC communication skills and other session/patient characteristics predict patient-reported outcomes. Four community advisory boards (CABs) and a genetic counselor advisory board will inform the study design and analysis., Ethics and Dissemination: This study has been approved by the single Institutional Review Board of the University of Minnesota. This research poses no greater than minimal risk to participants. Results from this study will be shared through national and international conferences and through community-based dissemination as guided by the study's CABs. A lay summary will also be disseminated to all participants., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024. Re-use permitted under CC BY-NC.

Evidence-based home visiting services (EBHV) are available in states and localities nationwide through the federally-funded Maternal, Infant, and Early Childhood Home Visiting (MIECHV) program. Nevertheless, the anticipated benefits of EBHV, such as improved child developmental outcomes and increased positive parenting practices, may be undermined by the fact that most families withdraw from services earlier than the model developers planned. Prior studies have linked family attrition with staff turnover. The current study used a mixed methods design to investigate the conditions under which families remained active in the home visiting program after their assigned home visitor resigned. Coincidence Analysis revealed that giving families advance notice (at least 1 month) prior to the home visitors' upcoming resignation or developing a strong positive working alliance with the inheriting home visitor appears to independently make a difference for ongoing family engagement at 3 and 6 months following a staff transition. These findings suggest that emphasizing how staff turnover is managed may mitigate the risk of family withdrawal during these transitions., (© 2024. The Author(s).)

Background: Exposures during pregnancy are common and most pregnant patients utilize at least one medication during pregnancy. The lack of reliable information on medication safety during pregnancy available to providers and patients is a stressor and obstacle to decision-making about medication use in pregnancy. Previous studies showed that exposures in pregnancy are associated with guilt, worry, and decisional conflict. Although prior research has evaluated changes in patient knowledge after teratogen counseling, studies have not examined emotional outcomes or patients' decisional empowerment. This quasi-experimental study measured changes in patients' feelings of guilt, anxiety, and decisional empowerment after receiving exposure counseling from trained teratogen information specialists., Methods: We administered pre- and post-counseling surveys to patients referred to a perinatal exposure clinic in Tampa, Florida. Validated scales were used to measure anxiety and guilt, and the 'SURE' measure was used to assess decisional empowerment. Paired samples t-tests evaluated changes in anxiety and guilt and a McNemar test assessed for changes in empowered decision making., Results: Among the 34 participants who completed both surveys, anxiety, and guilt scores decreased significantly (p < .001). While only 21% felt informed and empowered to make a decision related to their exposure(s) before counseling, this increased to 85% (p < .001) on the post-survey., Conclusion: Comprehensive counseling with a trained teratogen information specialist improves patient emotional outcomes as well as feelings of empowerment to make an informed decision regarding medication use in pregnancy. This study highlights that patient-centered teratogen counseling goes beyond simple changes in patient knowledge., (© 2024 Wiley Periodicals LLC.)

Introduction: The Implementing Universal Lynch Syndrome Screening (IMPULSS) study explained institutional variation in universal tumor screening (UTS) with the goal of identifying ways to aid organizational decision-makers in implementing and optimizing Lynch syndrome UTS programs., Methods: After applying the Consolidated Framework for Implementation Research (CFIR 1.0) to analyze interviews with 66 stakeholders across 9 healthcare systems to develop a toolkit for implementation, we adapted the International Patient Decision Aid Standards (IPDAS) to assess toolkit potential to aid decision-making consistent with organizational values. We then conducted user testing with two experienced and four non-experienced implementers of UTS to improve the content and functionality of the toolkit and assess its acceptability and appropriateness., Results: Toolkit components were organized to address findings related to CFIR 1.0 constructs of evidence strength and quality, relative advantage, cost, engaging, planning, executing, and reflecting and evaluating. A home page was added to direct users to different sections based on whether they are deciding to implement UTS, planning for implementation, improving an existing UTS program, or considering a different approach to identify patients with Lynch syndrome. Upon initial evaluation, 31 of 64 IPDAS criteria were met by the original toolkit. All users rated the toolkit as acceptable and appropriate for assisting organizational decision-making and identified multiple areas for improvement. Numerous iterative changes were made to the toolkit, resulting in meeting 17 of the previously unmet IPDAS criteria., Conclusion: We demonstrate the rigorous development of a toolkit guided by the CFIR and show how user testing helped improve the toolkit to ensure it is acceptable, appropriate, and meets most IPDAS criteria relevant to organizational values-based decision-making., (© 2024 The Author(s).

Background: Lynch syndrome (LS) is the most common cause of inherited colorectal cancer (CRC). Universal tumor screening (UTS) of newly diagnosed CRC cases is recommended to aid in diagnosis of LS and reduce cancer-related morbidity and mortality. However, not all health systems have adopted UTS processes and implementation may be inconsistent due to system and patient-level complexities., Methods: To identify barriers, facilitators, and suggestions for improvements of the UTS process from the patient perspective, we conducted in-depth, semi-structured interviews with patients recently diagnosed with CRC, but not screened for or aware of LS. Patients were recruited from eight regionally diverse US health systems. Interviews were conducted by telephone, 60-minutes, audio-recorded, and transcribed. An inductive, constant comparative analysis approach was employed.  RESULTS: We completed 75 interviews across the eight systems. Most participants were white (79%), about half (52%) were men, and the mean age was 60 years. Most self-reported either no (60%) or minimal (40%) prior awareness of LS. Overall, 96% of patients stated UTS should be a routine standard of care for CRC tumors, consistently citing four primary motivations for wanting to know their LS status and engage in the process for LS identification: "knowledge is power"; "family knowledge"; "prevention and detection"; and "treatment and surveillance." Common concerns pertaining to the process of screening for and identifying LS included: creating anticipatory worry for patients, the potential cost and the accuracy of the genetic test, and possibly having one's health insurance coverage impacted by the LS diagnosis. Patients suggested health systems communicate LS results in-person or by phone from a trained expert in LS; offer proactive verbal and written education about LS, the screening steps, and any follow-up surveillance recommendations; and support patients in communicating their LS screening to any of their blood relatives., Conclusion: Our qualitative findings demonstrate patients with CRC have a strong desire for healthcare systems to regularly implement and offer UTS. Patients offer key insights for health systems to guide future implementation and optimization of UTS and other LS screening programs and maximize diagnosis of individuals with LS and improve cancer-related surveillance and outcomes., Trial Registration: Not available: not a clinical trial., (© 2023.

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.

Background: Identifying key determinants is crucial for improving program implementation and achieving long-term sustainment within healthcare organizations. Organizational-level complexity and heterogeneity across multiple stakeholders can complicate our understanding of program implementation. We describe two data visualization methods used to operationalize implementation success and to consolidate and select implementation factors for further analysis., Methods: We used a combination of process mapping and matrix heat mapping to systematically synthesize and visualize qualitative data from 66 stakeholder interviews across nine healthcare organizations, to characterize universal tumor screening programs of all newly diagnosed colorectal and endometrial cancers and understand the influence of contextual factors on implementation. We constructed visual representations of protocols to compare processes and score process optimization components. We also used color-coded matrices to systematically code, summarize, and consolidate contextual data using factors from the Consolidated Framework for Implementation Research (CFIR). Combined scores were visualized in a final data matrix heat map., Results: Nineteen process maps were created to visually represent each protocol. Process maps identified the following gaps and inefficiencies: inconsistent execution of the protocol, no routine reflex testing, inconsistent referrals after a positive screen, no evidence of data tracking, and a lack of quality assurance measures. These barriers in patient care helped us define five process optimization components and used these to quantify program optimization on a scale from 0 (no program) to 5 (optimized), representing the degree to which a program is implemented and optimally maintained. Combined scores within the final data matrix heat map revealed patterns of contextual factors across optimized programs, non-optimized programs, and organizations with no program., Conclusions: Process mapping provided an efficient method to visually compare processes including patient flow, provider interactions, and process gaps and inefficiencies across sites, thereby measuring implementation success via optimization scores. Matrix heat mapping proved useful for data visualization and consolidation, resulting in a summary matrix for cross-site comparisons and selection of relevant CFIR factors. Combining these tools enabled a systematic and transparent approach to understanding complex organizational heterogeneity prior to formal coincidence analysis, introducing a stepwise approach to data consolidation and factor selection., (© 2023.

Background: Women with prenatal substance use have been identified as at-risk for the lack of engagement in perinatal services, such as medical care and home visitation programs. This issue is of particular concern in Florida (United States) where rates of fetal substance exposure have been steadily increasing., Methods: To identify pathways of and barriers to perinatal system and service engagement, journey mapping was used to compile various personas of perinatal women with substance use. A structured guide was developed to elicit maternal personas, system and service touchpoints, and system strengths and weaknesses from focus group participants with statewide stakeholders, including perinatal service administrators and community coalition members within three Florida communities. Workshop transcripts, debriefing, and member-checking sessions were transcribed verbatim and analyzed manually., Results: Six journey-mapping workshops and two member-checking meetings with mothers in-recovery were conducted with a total of 109 participants. Four personas were identified: women who (1) have substance use on a recreational basis, (2) have prescription drug use/misuse, (3) have chronic substance dependence, and (4) are in-recovery from substance dependence. Pathways that promote and barriers that prevent perinatal women with substance use from being identified, referred, or willing to accept and engage in medical care and social services were identified., Conclusions: While these personas shed light on differential pathways experienced by women with OUD, they were not intended as fixed-member groups but rather fluid descriptions of circumstances in which individuals could shift over time. These personas are beneficial to understand differences in circumstances, as well as variations in pathways and barriers to service engagement. Additionally, personas may be used to identify approaches to optimize service engagement by perinatal women with substance use and to support system improvements and integrations., (© 2023 Wiley Periodicals LLC.)

Purpose: Scalable solutions are needed to make pre-test genetic education about inherited cancer risk accessible across diverse and underserved populations. We evaluated an automated strategy to deliver genetic education through a web-based video among young Black females with breast cancer. Methods: 96 participants were recruited through state cancer registries in Florida and Tennesee. All participants viewed a 12 min video and completed a ten question quiz on inherited cancer knowledge before and after viewing the video. Median pre- and postvideo knowledge scores were categorized as <60% versus ≥60% and compared across demographic and clinical characteristics using binary logistic regression. Results: Of the 96 participants, mean age was 51, over 50% had income <$50 K, over 40% did not graduate college or have private insurance, and over 70% had previous genetic testing. Median knowledge scores significantly increased after viewing the video ( p  < 001), with no significant differences in those with or without prior testing. A higher post-video knowledge score was associated with an income ≥$50 K, a college degree, and private insurance (all p  < .05). Conclusion: Among a population of young Black breast cancer patients, the educational video significantly increased knowledge. Findings support the use of automated pre-test educational tools as a scalable solution to make these services more accessible across populations.

Genetic counselors (GCs) have traditionally been trained to adopt a position of equipoise or clinical neutrality. They provide information, answer questions, address barriers, and engage in shared decision-making, but generally, they do not prescribe a genetic test. Historically, GCs have generally been trained not to persuade the ambivalent or resistant patient. More recently, however, there has been discussion regarding when a greater degree of persuasion or directionality may be appropriate within genetic counseling (GC) and what role MI may play in this process. The role for "persuasive GC" is based on the premise that some genetic tests provide actionable information that would clearly benefit patients and families by impacting treatment or surveillance. For other tests, the benefits are less clear as they do not directly impact patient care or the benefits may be more subjective in nature, driven by patient values or psychological needs. For the former, we propose that GCs may adopt a more persuasive clinical approach while for the latter, a more traditional equipoise stance may be more appropriate. We suggest that motivational interviewing (MI) could serve as a unifying counseling model that allows GCs to handle both persuasive and equipoise encounters. For clearly beneficial tests, while directional, the MI encounter can still be non-directive, autonomy-supportive, and patient-centered. MI can also be adapted for equipoise situations, for example, placing less emphasis on eliciting and strengthening change talk as that is more a behavior change strategy than a shared decision-making strategy. The core principles and strategies of MI, such as autonomy support, evocation, open questions, reflective listening, and affirmation would apply to both persuasive and equipoise encounters. Key issues that merit discussion include how best to train GCs both during their initial and post-graduate education., (© 2022 The Authors.

Using a patient's genetic information to inform medication prescriptions can be clinically effective; however, the practice has not been widely implemented. Health systems need guidance on how to engage with providers to improve pharmacogenetic test utilization. Approaches from the field of implementation science may shed light on the complex factors affecting pharmacogenetic test use in real-world settings and areas to target to improve utilization. This paper presents an approach to studying the application of precision medicine that utilizes mixed qualitative and quantitative methods and implementation science frameworks to understand which factors or combinations consistently account for high versus low utilization of pharmocogenetic testing. This approach involves two phases: (1) collection of qualitative and quantitative data from providers-the cases-at four clinical institutions about their experiences with, and utilization of, pharmacogenetic testing to identify salient factors; and (2) analysis using a Configurational Comparative Method (CCM), using a mathematical algorithm to identify the minimally necessary and sufficient factors that distinguish providers who have higher utilization from those with low utilization. Advantages of this approach are that it can be used for small to moderate sample sizes, and it accounts for conditions found in real-world settings by demonstrating how they coincide to affect utilization.

Frameworks have been developed to help conceptualize clinical genetic counseling (GC), and observational studies have helped understand the process and content of GC sessions. However, additional research is needed to identify GC skills (behaviors or strategies) that practicing genetic counselors report consciously using to meet certain GC goals and determine what common terminology, if any, is being used to describe the various skills. Nineteen practicing genetic counselors in prenatal, pediatric, or cancer specialties were interviewed to elicit how they achieve session goals. Interview recordings were transcribed, coded thematically, and categorized using process categories from the communication strategy domain of the Framework for Outcomes in Clinical Communication Services (FOCUS). Reported skills largely fit within FOCUS, though findings prompted minor modifications of several FOCUS process categories and consolidation of the categories from 13 into 10. Although genetic counselor respondents reported a broad range of strategies and behaviors, they rarely had terms for skills they described. Results reveal concrete examples of GC skills, provide evidence for refinement of FOCUS, and highlight the need for establishing common terminology to describe these skills., (© 2022 National Society of Genetic Counselors.)

Current genetic counseling practice has not been found to significantly increase risk communication between family members. A more diverse set of genetic counseling approaches may be needed. A genetic counseling intervention based on motivational interviewing principles and the extended parallel process model was utilized to increase cascade outcomes within families with familial hypercholesterolemia, a common, underdiagnosed, and treatable condition. Parents of children with familial hypercholesterolemia were invited to participate in an online pre-survey, single-session genetic counseling intervention, and post-intervention surveys as a part of the CHEERS (Cholesterol Evaluation to Explore Risk Screening) intervention. This study investigated the efficacy of a genetic counselor delivered motivational interviewing intervention and how parents of children with familial hypercholesterolemia react by assessing family member cholesterol screening and risk communication to at-risk relatives. Transcripts were audio-recorded, transcribed, and analyzed for change talk using the Motivational Interviewing Skill Code version 2.1. Participant surveys were analyzed for self-reported extended parallel process constructs and motivations. Coincidence analysis was conducted to explore differences between those with and without positive cascade outcomes within 12 months after the intervention. On average, change talk increased during the session in order of the extended parallel process constructs (perceived severity, susceptibility, response efficacy, self-efficacy). Coincidence analysis revealed that 6 of the 7 cases with positive cascade outcomes were explained by either the presence of high change talk during the intervention or presence of positive motivations shortly after, while 5 of the 5 cases without a positive outcome lacked both of these key factors that were associated with cascade outcomes. Results of this study suggest that incorporating motivational interviewing and the extended parallel process model increases change talk and that the presence of either high levels of change talk or positive motivations is associated with positive cascade outcomes., (© 2022 National Society of Genetic Counselors.)

To address the increasing demand for inherited cancer genetic testing, we developed and evaluated a web-based educational tool to streamline genetic counseling (GC). Consented patients viewed the initial prototype containing core content (Version 1-Core) and provided feedback through three open-ended survey questions. Additional data were collected through individual interviews from a subgroup who viewed an enhanced version (Version 1-Enhanced), consisting of the same core content and additional optional content. Data were coded to synthesize most commonly repeated themes and conceptualize action items to guide refinement strategies. Of 305 participants, 80 responded to open-ended survey questions to suggest refinement strategies, after viewing Version 1-Core. Interviews with a subgroup of seven participants, who viewed Version 1-Enhanced, provided additional feedback. Of 11 unique action items identified, five overlapped across datasets (provide instructions, simplify language, improve visuals, embed knowledge questions with explanations, include more insurance-related information), three were identified only through open-ended survey data (incorporate automatic progression, clarify test result information, increase interactive content), and three were identified only through interviews (ensure core content is viewed, incorporate progress bar, feature embedded optional content at the end of the tool). Ten action items aligned with underlying tool objectives to provide an interactive online pre-test GC solution and were used to guide refinement strategies. Our results demonstrate the value of rigorous qualitative data collection and analysis in health research and the use of the self-directed learning framework and eHealth strategies to leverage technology in scaling up and innovating the delivery of pre-test GC for inherited cancer., (© 2021.

Familial hypercholesterolemia (FH) is an inherited condition resulting in increased risk of premature cardiovascular disease. This risk can be reduced with early diagnosis and treatment, but it can be challenging to identify individuals with FH. Cascade screening, the most efficient and cost-effective identification method, requires FH patients to communicate with their at-risk family and encourage them to pursue screening. Beyond FH, patients with conditions increasing disease risk to family members report barriers to the communication process such as insufficient knowledge of the condition and discomfort informing relatives. We conducted a pilot study of a genetic counseling intervention incorporating behavior-change principles from motivational interviewing (MI) and the extended parallel process model (EPPM) to help parents of children with FH overcome these barriers and improve cascade screening rates for FH. Of the 13 participants who completed the intervention and post-intervention surveys, 6 reported contacting and/or screening additional relatives. A large effect size in increasing communication and screening was observed (η 2  = 0.20), with the mean percent of at-risk relatives contacted rising from 33% to 45%, and the mean percent screened rising from 32% to 42%. On average, 2.23 new relatives were contacted and 2.46 were screened, per participant, by the end of the study. Direct content analysis revealed that despite the open-ended nature of the goal-setting process, participant goals fell into two categories including those who set goals focused on communicating with and screening family members (n = 9) and those who set goals only focused on managing FH (n = 4). Overall, the communication and screening rates reported after the intervention were higher than previous observations in adult FH populations. These results suggest this EPPM/MI genetic counseling intervention could be a useful tool for increasing communication and cascade screening for FH. With further research on goal-setting techniques, the intervention could be refined and replicated to identify more individuals affected by FH or modified for use with other actionable genetic conditions., (© 2021 National Society of Genetic Counselors.)

Reasons for limited ethnic and racial diversity among genetic counselors in the United States may be elucidated through better understanding the experiences of individuals from racial/ethnic minority backgrounds who are enrolled in genetic counseling graduate programs as well as recent graduates. Semi-structured interviews were conducted with racial/ethnic minority participants using Journey Mapping to elicit touchpoints that positively or negatively impact success at varying points along the path to becoming genetic counselors. Negative impacts observed at various touchpoints included the following: late awareness of the profession; observing lack of diversity in the field; financial burden of the application process; and microaggressions from peers, program leadership, and clinical supervisors. Positive impacts observed at various touchpoints included the following: group or personal mentors; opportunities to interact with practicing genetic counselors; opportunities to perform 'mock' admissions interviews; program interviews with a conversational interview style; and attending programs in cities with racially/ethnically diverse patient populations. Findings from this research suggest the lack of adequate infrastructure necessary to recruit and support racial/ethnic minority students is a critical systemic issue impeding progress toward diversifying the genetic counseling field. As such, this study reinforces the need for development, adaptation, and implementation of evidence-based strategies to optimize experiences of racial and ethnic minority individuals throughout the entire process of becoming a genetic counselor., (© 2021 National Society of Genetic Counselors.)

Background: Implementing genetic testing for inherited cancer predisposition into routine clinical care offers a tremendous opportunity for cancer prevention and early detection. However, genetic testing itself does not improve outcomes; rather, outcomes depend on implemented follow-up care. The IMPACT study is a hybrid type I randomized effectiveness-implementation trial to simultaneously evaluate the effectiveness of two interventions for individuals with inherited cancer predisposition focused on: 1) increasing family communication (FC) of genetic test results; and 2) improving engagement with guideline-based cancer risk management (CRM)., Methods: This prospective study will recruit a racially, geographically, and socioeconomically diverse population of individuals with a documented pathogenic/likely pathogenic (P/LP) variant in an inherited cancer gene. Eligible participants will be asked to complete an initial trial survey and randomly assigned to one of three arms: A) GeneSHARE, a website designed to increase FC of genetic test results; B) My Gene Counsel's Living Lab Report, a digital tool designed to improve understanding of genetic test results and next steps, including CRM guidelines; or C) a control arm in which participants continue receiving standard care. Follow-up surveys will be conducted at 1, 3, and 12 months following randomization. These surveys include single-item measures, scales, and indices related to: 1) FC and CRM behaviors and behavioral factors following the COM-B theoretical framework (i.e., capability, opportunity, and motivation); 2) implementation outcomes (i.e., acceptability, appropriateness, exposure, and reach); and 3) other contextual factors (i.e., sociodemographic and clinical factors, and uncertainty, distress, and positive aspects of genetic test results). The primary outcomes are an increase in FC of genetic test results (Arm A) and improved engagement with guideline-based CRM without overtreatment or undertreatment (Arm B) by the 12-month follow-up survey., Discussion: Our interventions are designed to shift the paradigm by which individuals with P/LP variants in inherited cancer genes are provided with information to enhance FC of genetic test results and engagement with guideline-based CRM. The information gathered through evaluating the effectiveness and implementation of these real-world approaches is needed to modify and scale up adaptive, stepped interventions that have the potential to maximize FC and CRM., Trial Registration: This study is registered at Clinicaltrials.gov (NCT04763915, date registered: February 21, 2021)., Protocol Version: September 17th, 2021 Amendment Number 04., (© 2021.

Research on genetic counseling outcomes has examined a range of metrics many that differ in quality and extent of psychometric assessment and in some cases fail to encompass potential benefits of genetic counseling for patients. Although a variety of possible outcomes have been explored, selecting the most important or relevant outcomes and identifying well-validated measures remain challenging. An online, modified Delphi method was used to prioritize genetic counseling outcomes from the viewpoint of individuals from four stakeholder groups - clinical genetic counselors, outcome researchers, genetic counseling training directors, and genetic counseling consumers/advocates. A survey of 181 genetic counseling outcomes were rated based on perceived importance and then sorted and categorized using the Framework for Outcomes of Clinical Communication Services in Genetic Counseling (FOCUS-GC) framework. Three of the FOCUS-GC domains (Process, Patient Care Experience, and Patient Changes) were assessed as most important, while none of the most highly rated outcomes fell into the domains of Patient Health or Family Changes. The majority of outcomes deemed most important by stakeholder groups were within the process domain. When looking at the proportion of outcomes that overlapped with the consumer group, clinical genetic counselors had the highest degree of similarity with consumers when looking at the high relative importance band outcomes (61.1% overlap), followed by training directors (58.3%), and outcome researchers (41.7%). Variability in importance according to stakeholder groups was an important consideration and prioritizing outcomes was challenging given that the majority of outcomes were rated as important. Working to bridge the realities of clinical care and fundamental differences in the viewpoints and priorities of genetic counseling research directions is an area for future exploration., (© 2020 National Society of Genetic Counselors.)

Identification of inherited breast cancer may guide care. These benefits can be amplified through communication of genetic test results with at-risk family members and subsequent family testing (FT). Females with a pathogenic/likely pathogenic (P/LP) variant in BRCA1/2, PALB2, CHEK2, and/or ATM were surveyed about family communication (FC) of genetic test results and FT. Comparisons were made across genes. The 235 participants with P/LP variants (186 BRCA1/2, 28 PALB2, 15 CHEK2, and 6 ATM) had a median age of 54 and most were non-Hispanic whites (89%) with a prior breast cancer diagnosis (61%). When controlling for other variables, FC was higher among younger participants (p<.0001), those with high FC self-efficacy (p=.019), and those with P/LP variants in BRCA1/2 compared to PALB2 (p =.040) and ATM/CHEK2 (p =.032). Higher rates of FC and FT were also observed among female relatives and relatives of closer kinship. Overall 94% of participants would find one or more resources helpful with FC and 70% reported using FC resources when telling family members about their genetic test result. The three most commonly used resources included the following: (a) a family sharing letter (38%); (b) printed materials (30%); and (c) web-based information (23%). Among the 86% who spoke with a genetic counselor (GC), 93% were given at least one FC resource and the three most common resources GCs provided to participants overlapped with the resources participants would find helpful and those that were used. Our results suggest lower FC and FT rates among women with P/LP variants in genes other than BRCA1/2, the reasons for which should be evaluated in future studies. As more data to refine cancer risks and management are generated across these other inherited breast cancer genes, strategies to improve FC and FT are needed to amplify the benefits of genetic testing., (© 2020 National Society of Genetic Counselors.)

Objective: This study explored motivators and challenges/barriers to sharing personal genetic test results (GTR) with family members (FM)., Methods: Semi-structured, in-depth interviews were conducted with 62 women who had a pathogenic or likely pathogenic (P/LP) variant in aBRCA, PALB2, CHEK2, or ATM gene. Selective qualitative data analysis focused on eliciting motivators and challenges/barriers identified by participants when sharing their GTR with FM., Results: Motivators to sharing personal GTR with FM included: health protection and prevention; moral obligation; decisional empowerment; familial ties; written resources; and contextualization for a familial cause for cancer. Challenges/barriers to family sharing included: concern for FM reactions; complexities of information; lack of closeness; perceived relevance; and emotional impact., Conclusions: All motivators and challenges/barriers were identified across BRCA and non-BRCA carriers, demonstrating commonalities in family sharing of GTR among high- to moderate-penetrance hereditary BC (breast cancer) genes. Despite challenges/barriers, participants disclosed their GTR with most close FM, yet restrictions in communication and/or strain on the timing, manner of disclosing, and strategies used varied across certain FM., Practice Implications: These findings offer healthcare providers and researchers preliminary practical implications for broadly improving family sharing interventions across P/LP variants in BC risk genes by demonstrating important elements to include in family sharing letters., Competing Interests: Declaration of Competing Interest The authors report no declarations of interest., (Copyright © 2021 Elsevier B.V.

Background: Implementation of multifaceted interventions typically involves many diverse elements working together in interrelated ways, including intervention components, implementation strategies, and features of local context. Given this real-world complexity, implementation researchers may be interested in a new mathematical, cross-case method called Coincidence Analysis (CNA) that has been designed explicitly to support causal inference, answer research questions about combinations of conditions that are minimally necessary or sufficient for an outcome, and identify the possible presence of multiple causal paths to an outcome. CNA can be applied as a standalone method or in conjunction with other approaches and can reveal new empirical findings related to implementation that might otherwise have gone undetected., Methods: We applied CNA to a publicly available dataset from Sweden with county-level data on human papillomavirus (HPV) vaccination campaigns and vaccination uptake in 2012 and 2014 and then compared CNA results to the published regression findings., Results: The original regression analysis found vaccination uptake was positively associated only with the availability of vaccines in schools. CNA produced different findings and uncovered an additional solution path: high vaccination rates were achieved by either (1) offering the vaccine in all schools or (2) a combination of offering the vaccine in some schools and media coverage., Conclusions: CNA offers a new comparative approach for researchers seeking to understand how implementation conditions work together and link to outcomes.

We have entered an era of direct-to-consumer (DTC) genomics. Patients have relayed many success stories of DTC genomics about finding causal mutations of genetic diseases before showing any symptoms and taking precautions. However, consumers may also take unnecessary medical actions based on false alarms of "pathogenic alleles". The severity of this problem is not well known. Using publicly available data, we compared DTC microarray genotyping data with deep-sequencing data of 5 individuals and manually checked each inconsistently reported single nucleotide variants (SNVs). We estimated that, on average, a person would have ~5 "pathogenic" alleles reported due to wrongly reported genotypes if using a 23andMe genotyping microarray. We also found that the number of wrongly classified "pathogenic" alleles per person is at least as significant as those due to wrongly reported genotypes. We show that the scale of the false alarm problem could be large enough that the medical costs will become a burden to public health.

Background: Increasing use of genetic tests have identified many variants of uncertain significance (VUS) in genes associated with inherited arrhythmias and cardiomyopathies. Evaluation of clinical practices, including medical management recommendations for VUS patients and their families, is important to prevent over- or under-treatment that may result in morbidity or mortality. The purpose of this study is to describe practices related to VUS results including information and medical management recommendations providers give patients and their families., Methods: An anonymous online survey was distributed to genetic counselors (GCs) and cardiologists who have seen at least one patient for inherited arrhythmias or cardiomyopathies. The survey explored providers' confidence in counseling, explanation of VUSs, topics covered before and after genetic testing, and clinical recommendations using a hypothetical scenario maximizing uncertainty with an unclear clinical and molecular diagnosis. Descriptive statistics were calculated, and median confidence and likelihood of making various medical recommendations were compared across provider type., Results: Providers (N=102) who completed the survey included 29 cardiovascular GCs, 50 GCs from other specialties, and 23 cardiologists. GCs feel more confident than cardiologists counseling about VUS results ( P <0.001); while both cardiovascular GCs and cardiologists feel more confident than other GCs in providing input regarding medical management recommendations ( P =0.001 and P =0.01, respectively). Cardiologists were more likely than cardiac GCs to recommend clinical testing for family members even though testing in the scenario is expected to be uninformative., Conclusions: These findings illustrate how the expertise of different providers may impact decision processes, suggesting the need for interdisciplinary clinics to optimize care for challenging cases.

Background: Increasing demand for genetic testing for inherited cancer risk coupled with a shortage of providers trained in genetics highlight the potential for automated tools embedded in the clinic process to meet this demand. We developed and tested a scalable, easy-to-use, 12-minute web-based educational tool that included standard pretest genetic counseling elements related to panel-based testing for multiple genes associated with cancer risk., Methods: The tool was viewed by new patients at the Vanderbilt Hereditary Cancer Clinic before meeting with a board-certified genetics professional. Pre- and post-tool surveys measured knowledge, feeling informed/empowered to decide about testing, attitudinal values about genetic testing, and health literacy. Of the initial 100 participants, 50 were randomized to only have knowledge measured on the post-tool survey to assess for a priming effect., Results: Of 360 patients approached, 305 consented and completed both the pre- and post-tool surveys, with a mean age of 47 years, including 80% female patients and 48% patients with cancer. Survey results showed an increase in knowledge and feeling informed/empowered after viewing the tool (P<.001), but no significant change in attitude (P=.64). Post-tool survey data indicated no difference in median knowledge between low and high health literacy groups (P=.30). No priming effect was present among the initial 100 participants (P=.675)., Conclusions: Viewing the educational tool resulted in significant gains in knowledge across health literacy levels, and most individuals felt informed and empowered to decide about genetic testing. These findings indicate that the use of an automated pretest genetic counseling tool may help streamline the delivery of genetic services.

Purpose: Identification of inherited breast cancer may guide cancer risk management. We sought to compare risk management practices across women with inherited breast cancer genes., Methods: Females with a pathogenic/likely pathogenic (P/LP) variant in BRCA1/2, PALB2, CHEK2, and/or ATM were surveyed about cancer risk management. Comparisons were made across genes., Results: The 235 participants with P/LP variants (186 BRCA1/2, 28 PALB2, 15 CHEK2, and 6 ATM) had a median age of 54 and 61% had a prior breast cancer diagnosis. For women with P/LP variants in BRCA1/2, PALB2, and ATM/CHEK2, bilateral mastectomy (BM) rates were 79%, 61%, and 52%, and bilateral oophorectomy (BO) rates were 89%, 30%, and 37%, respectively. Among women with P/LP variants in PALB2 and ATM/CHEK2, 27% of those who had a BO had a family history of ovarian cancer. Contralateral mastectomy rates for women with P/LP variants in PALB2 and ATM/CHEK2 with unilateral breast cancer were 60% and 58%, and BM rates for those without breast cancer were 57% and 29%, respectively., Conclusion: These findings suggest high rates of both contralateral mastectomies among those with unilateral breast cancer and BM among those without a breast cancer diagnosis across women with P/LP variants in high and moderate penetrance breast cancer genes. BO was also often utilized for risk reduction across these women. These findings suggest potential overtreatment through risk-reducing surgery, and highlight the importance of promoting guideline-adherent, risk-appropriate care.

Purpose: All women diagnosed with breast cancer (BC) ≤age 50 should be referred for genetic counseling (GC) and testing. We sought to compare differences in provider practices and access across a racially and ethnically diverse population of young BC survivors., Methods: A registry-based sample of women diagnosed with invasive BC ≤age 50 from 2009 to 2012 was recruited through the Florida Cancer Registry, and completed a questionnaire and medical record release. Differences were compared across those tested with or without the involvement of a board-certified or credentialed genetics health professional (GHP) in (1) clinical and demographic variables and (2) pretest GC elements., Results: Of 1622 participants, there were 440 Blacks, 285 Hispanics, and 897 Non-Hispanic Whites. Of 831 participants with medical record verification of testing provider, 170 (20%) had documentation of GHP involvement. Among the 613 who recalled a pretest discussion and had GC elements collected, those with GHP involvement were significantly more likely to recall the seven recognized GC elements., Conclusion: GHP involvement was associated with adherence to nationally recommended best practices. With the expanding importance of identifying inherited cancers, it is critical to ensure equitable access to best practices across all populations.

Despite higher incidence and mortality of breast cancer among younger Black women, genetic testing outcomes remain severely understudied among Blacks. Past research on disclosure of genetic testing results to family members has disproportionately focused on White, educated, high socioeconomic status women. This study addresses this gap in knowledge by assessing (a) to whom Black women disclose genetic test results and (b) if patterns of disclosure vary based on test result (e.g., BRCA1/2 positive, negative, variant of uncertain significance [VUS]). Black women (N = 149) with invasive breast cancer diagnosed age ≤50 years from 2009 to 2012 received free genetic testing through a prospective, population-based study. At 12 months post-testing, women reported with whom they shared their genetic test results. The exact test by binomial distribution was used to examine whether disclosure to female relatives was significantly greater than disclosure to male relatives, and logistic regression analyses tested for differences in disclosure to any female relative, any male relative, parents, siblings, children, and spouses by genetic test result. Most (77%) women disclosed their results to at least one family member. Disclosure to female relatives was significantly greater than disclosure to males (p < .001). Compared to those who tested negative or had a VUS, BRCA1/2-positive women were significantly less likely to disclose results to their daughters (OR BRCA positive  = 0.25, 95% CI = 0.07-0.94, p = .041) by 12 months post-genetic testing. Genetic test result did not predict any other type of disclosure (all ps > 0.12). Results suggest that in Black families, one benefit of genetic testing-to inform patients and their family about cancer risk information-is not being realized. To increase breast cancer preventive care among high-risk Black women, the oncology care team should prepare Black BRCA1/2-positive women to share genetic test results with family members and, in particular, their daughters., (© 2020 National Society of Genetic Counselors.)

Background: Black women are overrepresented among premenopausal breast cancer (BC) survivors. These patients warrant genetic testing (GT) followed by risk-reducing behaviors. This study documented patterns and predictors of cancer risk-management behaviors among young black BC survivors after GT., Methods: Black women (n = 143) with a diagnosis of BC at the age of 50 years or younger received GT. At 1 year after GT, participants reported receipt of risk-reducing mastectomy, risk-reducing salpingo-oophorectomy, mammogram, breast magnetic resonance imaging (MRI), CA125 test, and transvaginal/pelvic ultrasound. Logistic regression was used to examine predictors of BC risk management (risk-reducing mastectomy or breast MRI) and ovarian cancer risk management (risk-reducing salpingo-oophorectomy, CA125 test, or transvaginal/pelvic ultrasound)., Results: Of the study participants, 16 (11%) were BRCA1/2-positive, 43 (30%) had a variant of uncertain significance, and 84 (59%) were negative. During the 12 months after GT, no women received risk-reducing mastectomy. The majority (93%) received a mammogram, and a smaller proportion received breast MRI (33%), risk-reducing salpingo-oophorectomy (10%), CA125 test (11%), or transvaginal/pelvic ultrasound (34%). Longer time since the BC diagnosis predicted lower likelihood of BC risk management (odds ratio [OR] 0.54). BRCA1/2 carrier status (OR 4.57), greater perceived risk of recurrence (OR 8.03), and more hereditary breast and ovarian cancer knowledge (OR 1.37) predicted greater likelihood of ovarian cancer risk management., Conclusions: Young black BC survivors appropriately received mammograms and ovarian cancer risk management based on their BRCA1/2 test result. However, the low usage of MRI among BRCA1/2 carriers contrasts with national guidelines. Future research should examine barriers to MRI among black BC survivors. Finally, modifiable variables predicting risk management after GT were identified, providing implications for future interventions.

As genetic counseling services expand and reach a wider catchment of the population, there is a critical need to better understand the impact of services on a greater diversity of patients. We conducted a systematic review to evaluate genetic counseling experiences and outcomes among racial and ethnic minorities. Six databases extracted articles published from 2005 to 2019 that assessed genetic counseling participation, knowledge and awareness, motivators, barriers, perceptions, and outcomes for racial and ethnic minority populations in the United States. Genetic counseling outcomes were categorized using the Framework for Outcomes of Clinical commUnication Services. A total of 1,227 abstracts were identified, of which 23 papers met inclusion criteria. Results suggest the possibility of racial and ethnic differences in some genetic counseling experiences and outcomes but noted differences were not adequately replicated between studies. The few included studies differed greatly in aims, methods, and results, which made comparison across study designs challenging and effectively barred thematic analysis. Additional research is needed that includes more study populations and settings with patients of diverse racial and ethnic backgrounds, as well as more structured study designs that allow for elucidations of differences between White and non-White populations., (© 2020 National Society of Genetic Counselors.)

Importance: Informed consent in rhinoplasty is a challenging process due to the technically demanding surgery with a wide array of potential complications. Objective: To underscore the significance of informed consent in rhinoplasty, its complications, and identify gaps in the consent process. Design, Setting, and Participants: Dual search and comparison. First a review of the literature for rhinoplasty articles was carried out between January 2000 and November 2017 with at least 100 patients to identify complications and their incidences. Then a comprehensive online search for rhinoplasty consent forms was carried out to identify consent form topics and their incidences. Main Outcomes and Measures: Consent form topics and complication rates from the literature review were reported and directly compared. Results: A total of 117 articles were included, with 36 different complications reported. Twenty-four consent forms were evaluated, yielding 80 different topics. Common complications within the literature included skin problems such as acne (18.3%), numbness (16.7%), hospital revisit (6.5%), primary source revision rate (5.3%), and dissatisfaction (5.0%). The most commonly covered consent topics included infection (100%), bleeding (95.8%), and scarring (95.8%). Unsatisfactory results and need for revision were only covered in 83.3% and 75.0% of consent forms, respectively, despite both being in the top 5 complications cited in the literature. Conclusions and Relevance: Rhinoplasty consent forms generally cover a wide range of topics, with varying incidences of complications cited within the literature. Certain complications such as dissatisfaction and revision surgery should be included in every consent process. These data help provide a contextual framework as well as valuable information in preoperative counseling for patients and physicians regarding rhinoplasty and its potential complications Level of Evidence: NA.

Importance: Nasal base view is important for rhinoplasty analysis. Although some descriptors of nasal base shape exist, they are largely subjective and qualitative., Objective: To evaluate a parametric model of nasal base shape and compare it with categorization by surgeons to create an objective classification system for clinical evaluation and communication., Design, Setting, and Participants: Retrospective cohort review of deidentified photographs of 420 patients evaluated for possible facial plastic surgery at a tertiary care academic medical center between January 2013 and June 2017. The nasal bases were classified into 6 shape categories (equilateral, boxy, cloverleaf, flat, round, and narrow) via visual inspection. The contour of each nasal base was traced using MATLAB software (MathWorks Inc). The software then performed a curve fit to the parametric model with output of values for 5 parameters: projection-to-width ratio, the anterior-posterior positioning of the tip bulk, symmetry, degree of lateral recurvature of the nasal base, and size. The differences among shape categories for each parameter were analyzed using 1-way analysis of variance. Pairwise comparisons were then performed to ascertain how the various shapes differed. Finally, a multinomial logistic regression model was used to predict nasal base shape using parameter values. Data were analyzed between April 2017 and January 2018., Main Outcomes and Measures: An algorithm that categorized nasal base shapes into 6 categories., Results: The 420 nasal base photographs of patients evaluated for possible plastic surgery were categorized into 1 of 6 categories; 305 photographs were readily classified, and the remaining 115 were termed unclassified and were categorized. For both the classified and unclassified nasal base groups, there were statistically significant differences between projection-to-width ratio (classified, F5,299 = 21.51; unclassified, F4,100 = 10.59; P < .001), the anterior-posterior positioning of the tip bulk (classified, F5,299 = 3.76; P = .003; unclassified, F4,110 = 4.54; P = .002), and degree of lateral recurvature of the nasal base (classified, F5,299 = 24.14; unclassified, F4,100 = 7.21; P < .001). A multinomial logistic regression model categorization was concordant with surgeon categorization in 201 of 305 (65.9%) cases of classified nasal bases and 38 of 115 (33.0%) unclassified nasal bases., Conclusions and Relevance: The parametric model may provide an objective and numerical approach to analyzing nasal base shape., Level of Evidence: NA.
