Perspectives of adults with neurofibromatosis regarding the design of psychosocial trials: Results from an anonymous online survey.

BACKGROUND/AIMS: Individuals with neurofibromatosis, including neurofibromatosis 1 (NF1), neurofibromatosis 2 (NF2)-related schwannomatosis (SWN), and other forms of SWN, often experience disease manifestations and mental health difficulties for which psychosocial interventions may help. An anonymous online survey of adults with neurofibromatosis assessed their physical, social, and emotional well-being and preferences about psychosocial interventions to inform clinical trial design. METHODS: Neurofibromatosis clinical researchers and patient representatives from the Response Evaluation in Neurofibromatosis and Schwannomatosis International Collaboration developed the survey. Eligibility criteria included age ≥ 18 years, self-reported diagnosis of NF1, NF2, or SWN, and ability to read and understand English. The online survey was distributed internationally by the Neurofibromatosis Registry and other neurofibromatosis foundations from June to August 2020. RESULTS: Surveys were completed by 630 adults (18-81 years of age; M = 45.5) with NF1 (78%), NF2 (14%), and SWN (8%) who were mostly White, not Hispanic/Latino, female, and from the United States. The majority (91%) reported that their neurofibromatosis symptoms had at least some impact on daily life. In the total sample, 51% endorsed a mental health diagnosis, and 27% without a diagnosis believed they had an undiagnosed mental health condition. Participants indicated that neurofibromatosis affected their emotional (44%), physical (38%), and social (35%) functioning to a high degree. Few reported ever having participated in a drug (6%) or psychosocial (7%) clinical trial, yet 68% reported they "probably" or "definitely" would want to participate in a psychosocial trial if it targeted a relevant concern. Top treatment targets were anxiety, healthier lifestyle, and daily stress. Top barriers to participating in psychosocial trials were distance to clinic, costs, and time commitment. Respondents preferred interventions delivered by clinicians via individual sessions or a combination of group and individual sessions, with limited in-person and mostly remote participation. There were no significant group differences by neurofibromatosis type in willingness to participate in psychosocial trials (p = 0.27). Regarding interest in intervention targets, adults with SWN were more likely to prefer psychosocial trials for pain support compared to those with NF1 (p < 0.001) and NF2 (p < 0.001). CONCLUSION: This study conducted the largest survey assessing physical symptoms, mental health needs, and preferences for psychosocial trials in adults with neurofibromatosis. Results indicate a high prevalence of disease manifestations, psychosocial difficulties, and untreated mental health problems in adults with neurofibromatosis and a high degree of willingness to participate in psychosocial clinical trials. Patient preferences should be considered when designing and implementing psychosocial interventions to develop the most feasible and meaningful studies.

Recommendations for assessing appearance concerns related to plexiform and cutaneous neurofibromas in neurofibromatosis 1 clinical trials.

BACKGROUND/AIMS: Individuals with neurofibromatosis 1 may experience changes in their appearance due to physical manifestations of the disorders and/or treatment sequelae. Appearance concerns related to these physical changes can lead to psychological distress and poorer quality of life. While many neurofibromatosis 1 clinical trials focus on assessing changes in tumor volume, evaluating patients' perspectives on corresponding changes in symptoms such as physical appearance can be key secondary outcomes. We aimed to determine whether any existing patient-reported outcome measures are appropriate for evaluating changes in appearance concerns within neurofibromatosis 1 clinical trials. METHODS: After updating our previously published systematic review process, we used it to identify and rate existing patient-reported outcome measures related to disfigurement and appearance. Using a systematic literature search and initial triage process, we focused on identifying patient-reported outcome measures that could be used to evaluate changes in appearance concerns in plexiform or cutaneous neurofibroma clinical trials in neurofibromatosis 1. Our revised Patient-Reported Outcome Rating and Acceptance Tool for Endpoints then was used to evaluate each published patient-reported outcome measures in five domains, including (1) respondent characteristics, (2) content validity, (3) scoring format and interpretability, (4) psychometric data, and (5) feasibility. The highest-rated patient-reported outcome measures were then re-reviewed in a side-by-side comparison to generate a final consensus recommendation. RESULTS: Eleven measures assessing appearance concerns were reviewed and rated; no measures were explicitly designed to assess appearance concerns related to neurofibromatosis 1. The FACE-Q Craniofacial Module-Appearance Distress scale was the top-rated measure for potential use in neurofibromatosis 1 clinical trials. Strengths of the measure included that it was rigorously developed, included individuals with neurofibromatosis 1 in the validation sample, was applicable to children and adults, covered item topics deemed important by neurofibromatosis 1 patient representatives, exhibited good psychometric properties, and was feasible for use in neurofibromatosis 1 trials. Limitations included a lack of validation in older adults, no published information regarding sensitivity to change in clinical trials, and limited availability in languages other than English. CONCLUSION: The Response Evaluation in Neurofibromatosis and Schwannomatosis patient-reported outcome working group currently recommends the FACE-Q Craniofacial Module Appearance Distress scale to evaluate patient-reported changes in appearance concerns in clinical trials for neurofibromatosis 1-related plexiform or cutaneous neurofibromas. Additional research is needed to validate this measure in people with neurofibromatosis 1, including older adults and those with tumors in various body locations, and explore the effects of nontumor manifestations on appearance concerns in people with neurofibromatosis 1 and schwannomatosis.

Views on the impact of the COVID-19 pandemic on health in people with Down syndrome from diverse backgrounds.

Down syndrome (DS) has a unique medical and psychological profile. To date, few studies have asked individuals with DS about their views of health, and fewer have explored the impact of COVID-19 on the health of individuals with DS and their families. We used a mixed methods approach including two studies on the health of individuals with DS and their parents conducted during the COVID-19 pandemic: (1) eight virtual focus groups, comprised of 20 parents and 8 individuals with DS to obtain participants' views of health, and (2) a 20-item questionnaire on health care experience of patients with DS who are African American or come from primarily Spanish-speaking homes. Focus group transcripts were coded using a hybrid inductive/deductive framework and thematically analyzed using the Framework Method. This questionnaire included questions regarding the impact of COVID-19 on caregivers and their loved ones with DS; responses to these questions were summarized using descriptive statistics. Individuals with DS discussed the impact of the COVID-19 pandemic on their physical and social health including masking, online learning, and online communication with friends and family. Parents of individuals with DS discussed how the COVID-19 pandemic negatively impacted their child's physical, social, and mental health, as a result of virtual schooling and decreased socialization. There were unexpected positives of the pandemic such as improved hygiene and eased scheduling with telehealth visits. Caregivers noted COVID-19 impacted their own anxiety, employment, and other domains that have potential ripple effects on the health of their children. The COVID-19 pandemic had a pervasive impact on the mental health and wellness of caregivers as well as the physical, social, and mental health of individuals with DS.

Indicators of health in Down syndrome: A virtual focus group study with patients and their parents.

BACKGROUND: Down syndrome has a unique medical and psychological profile. To date, few studies have asked individuals with Down syndrome about their views of health. METHODS: Eight focus groups of 20 parents and 8 individuals with Down syndrome, were conducted virtually via videoconferencing to obtain participants' views of health indicators. Focus group moderators employed some modifications for individuals with Down syndrome, including simplified language and use of graphics. Transcripts were coded using a hybrid inductive/deductive framework and thematically analysed using the Framework Method. RESULTS: We describe lessons learned in conducting virtual focus groups of individuals with Down syndrome and their parents. Individuals with Down syndrome could describe their views of health indicators and identified many of the same topics as their parents. Both groups discussed physical, mental, and social health components. However, people with Down syndrome gave a more restricted range of examples, but with different nuances than parents. CONCLUSION: Partcipants discussed physical, social, and mental well-being components of health in Down syndrome. Interviewing individuals with Down syndrome in virtual focus groups with appropriate modifications added important self-report health information.

Ten-Year Follow-up of Internal Neurofibroma Growth Behavior in Adult Patients With Neurofibromatosis Type 1 Using Whole-Body MRI.

BACKGROUND AND OBJECTIVES: Internal neurofibromas, including plexiform neurofibromas (PNF), can cause significant morbidity in patients with neurofibromatosis type 1 (NF1). PNF growth is most pronounced in children and young adults, with more rapid growth thought to occur in a subset of PNF termed distinct nodular lesions (DNL). Growth behavior of internal neurofibromas and DNL in older adults is not well documented; yet knowledge thereof is important for patient risk stratification and clinical trial design. The primary objective of this study was to evaluate the long-term growth behavior of internal neurofibromas in adults with NF1. Secondary objectives were to correlate tumor growth behavior with patient-specific, tumor-specific, and patient-reported variables. METHODS: In this prospective cohort study, internal neurofibromas were identified on coronal short TI inversion recovery sequences on baseline and follow-up whole-body MRIs (WBMRIs). Tumor growth and shrinkage were defined as a volume change ≥20%. The association between tumor growth and patient-specific (baseline age, sex, and genotype), tumor-specific (morphology, location, DNL presence on baseline WBMRI, and maximum standardized uptake value on baseline PET imaging), and patient-reported variables (endogenous and exogenous hormone exposure, pain intensity, and quality of life) was assessed using the Spearman correlation coefficient and Kruskal-Wallis test. RESULTS: Of 106 patients with a baseline WBMRI obtained as part of a previous research study, 44 had a follow-up WBMRI. Three additional patients with WBMRIs acquired for clinical care were included, generating 47 adults for this study. The median age during baseline WBMRI was 42 years (range 18-70). The median time between WBMRIs was 10.4 years. Among 324 internal neurofibromas, 62.8% (56% of PNF and 62.1% of DNL) shrank spontaneously without treatment and 17.1% (17.9% of PNF and 13.8% of DNL) grew. Growth patterns were heterogeneous within participants. Patient-specific, tumor-specific, and patient-reported variables (including endogenous and exogenous hormone exposure) were not strong predictors of tumor growth. DISCUSSION: Internal neurofibroma growth behavior in older adults differs fundamentally from that in children and young adults, with most tumors, including DNL, demonstrating spontaneous shrinkage. Better growth models are needed to understand factors that influence tumor growth. These results will inform clinical trial design for internal neurofibromas.

Design of a randomized, placebo-controlled, phase 2 study evaluating the safety and efficacy of tanezumab for treatment of schwannomatosis-related pain.

BACKGROUND: Schwannomatosis (SWN) is a rare tumor suppressor syndrome that predisposes affected individuals to develop multiple schwannomas and, less often, meningiomas. The most common symptom is chronic, severe pain. No medications are broadly effective in treating SWN-associated pain. The clinical trial described in this manuscript is a phase 2, randomized, double-blind, placebo-controlled study investigating the safety and efficacy of tanezumab - a humanized monoclonal antibody that inhibits nerve growth factor - for treatment of SWN-related pain. As the first therapeutic trial for SWN-related pain, it also aims to evaluate trial endpoints, understand recruitment patterns, and improve clinical trial design in this rare disease. AIMS: The primary objective of this trial is to assess the analgesic efficacy of subcutaneous tanezumab 10 mg in subjects with SWN who continue pre-existing pain therapy (excluding non-steroidal anti-inflammatory drugs). The secondary objective is to assess safety in this population. Exploratory objectives include assessment of pain features, quality of life, and predictive biomarkers. METHODS: The study is comprised of four periods (pre-treatment, double-blind treatment, single-arm treatment, safety follow-up) across 10 months with a delayed-start trial design to allow all participants to receive tanezumab. Forty-six participants will be enrolled and randomized 1:1 to receive either tanezumab or placebo subcutaneously in the double-blind treatment period; all participants receive tanezumab during the single-arm treatment period. CONCLUSIONS: This study is the first therapeutic trial for SWN patients and targets a biological driver of SWN-related pain. It aims to establish a model for future pain studies in SWN and other rare diseases. CLINICAL TRIAL REGISTRATION: NCT04163419 on ClinicalTrials.gov.

Understanding barriers to diagnosis in a rare, genetic disease: Delays and errors in diagnosing schwannomatosis.

Diagnosis of rare, genetic diseases is challenging, but conceptual frameworks of the diagnostic process can guide quality improvement initiatives. Using the National Academy of Medicine diagnostic framework, we assessed the extent of, and reasons for diagnostic delays and diagnostic errors in schwannomatosis, a neurogenetic syndrome characterized by nerve sheath tumors and chronic pain. We reviewed the medical records of 97 people with confirmed or probable schwannomatosis seen in two US tertiary care clinics. Time-to-event analysis revealed a median time from first symptom to diagnosis of 16.7 years (95% CI, 7.5-26.0 years) and median time from first medical consultation to diagnosis of 9.8 years (95% CI, 3.5-16.2 years). Factors associated with longer times to diagnosis included initial signs/symptoms that were intermittent, non-specific, or occurred at younger ages (p < 0.05). Thirty-six percent of patients were misdiagnosed; misdiagnoses were of underlying genetic condition (18.6%), pain etiology (16.5%), and nerve sheath tumor presence/pathology (11.3%) (non-mutually exclusive categories). One-fifth (19.6%) of patients had a clear missed opportunity for genetics workup that could have led to an earlier schwannomatosis diagnosis. These results suggest that interventions in clinician education, genetic testing availability, expert review of pathology findings, and automatic triggers for genetics referrals may improve diagnosis of schwannomatosis.

Evaluating the Impacts of Patient Engagement on Health Services Research Teams: Lessons from the Veteran Consulting Network.

BACKGROUND: Despite increasing commitment to patient engagement in research, evaluation of the impact of these efforts on research processes, products, and teams is limited. OBJECTIVE: To explore the impacts of engaging patients as consultants to research studies by examining the experiences, impacts, and lessons learned from a program facilitating patient engagement at a Veterans Health Administration research center. DESIGN: We developed a logic model to articulate the activities being implemented to support patient engagement and their anticipated outcomes. Then, we conducted qualitative, semi-structured interviews with participants in the local Veteran Consulting Network to qualitatively explore these outcomes. PARTICIPANTS: Twelve researchers and eleven Veteran patients with experience working on at least one grant or funded study. APPROACH: Interview transcripts were inductively coded using a consensus-based approach. Findings were synthesized using framework analysis and mapped back onto our logic model of expected patient engagement impacts. KEY RESULTS: Patient engagement improved the perceived quality and relevance of research studies as patient consultants challenged researchers' assumptions about patient populations and clinical contexts and gave feedback that helped improve the feasibility of proposed grants, readability of study materials, comprehensiveness of study assessments, and cultural sensitivity and relevance of interventions. Patient engagement also had personal benefits to researchers and patients. Researchers reported improved communication skills and higher job satisfaction. Patients reported a sense of purpose and satisfaction from their work with greater awareness of and appreciation for research. CONCLUSIONS: Engaging patients in research can have multiple benefits to the people and work involved. Our evaluation process can serve as a template for other organizations to plan for and assess the impact of their own patient engagement programs. Creating logic models and updating them based on feedback from program users make engagement goals explicit, help verify expected mechanisms to achieve impact, and facilitate organizational learning.

Awareness and agreement with neurofibromatosis care guidelines among U.S. neurofibromatosis specialists.

INTRODUCTION: The neurofibromatoses (NF) are a group of rare, genetic diseases sharing a predisposition to develop multiple benign nervous system tumors. Given the wide range of NF symptoms and medical specialties involved in NF care, we sought to evaluate the level of awareness of, and agreement with, published NF clinical guidelines among NF specialists in the United States. METHODS: An anonymous, cross-sectional, online survey was distributed to U.S.-based NF clinicians. Respondents self-reported demographics, practice characteristics, awareness of seven NF guideline publications, and level of agreement with up to 40 individual recommendations using a 5-point Likert scale. We calculated the proportion of recommendations that each clinician rated "strongly agree", and assessed for differences in guideline awareness and agreement by respondent characteristics. RESULTS: Sixty-three clinicians (49% female; 80% academic practice) across > 8 medical specialties completed the survey. Awareness of each guideline publication ranged from 53%-79% of respondents; specialists had higher awareness of publications endorsed by their medical professional organization (p < 0.05). The proportion of respondents who "strongly agree" with individual recommendations ranged from 17%-83%; for 16 guidelines, less than 50% of respondents "strongly agree". There were no significant differences in overall agreement with recommendations based on clinicians' gender, race, specialty, years in practice, practice type (academic/private practice/other), practice location (urban/suburban/rural), or involvement in NF research (p > 0.05 for all). CONCLUSIONS: We identified wide variability in both awareness of, and agreement with, published NF care guidelines among NF experts. Future quality improvement efforts should focus on evidence-based, consensus-driven methods to update and disseminate guidelines across this multi-specialty group of providers. Patients and caregivers should also be consulted to proactively anticipate barriers to accessing and implementing guideline-driven care. These recommendations for improving guideline knowledge and adoption may also be useful for other rare diseases requiring multi-specialty care coordination.

Impact of the coronavirus pandemic on mental health and health care in adults with neurofibromatosis: Patient perspectives from an online survey.

The coronavirus pandemic increased anxiety and stress and prevented access to health care worldwide; it is unclear how COVID-19 affected adults with a multisystem genetic disorder such as neurofibromatosis (NF). An anonymous online survey was distributed through an international registry and foundations to adults with NF (June-August 2020) to assess the impact of the pandemic on mental health and NF health care. Six hundred and thirteen adults (18-81 years; M = 45.7) with NF1 (77.8%), NF2 (14.2%), and schwannomatosis (7.8%) provided complete responses. Respondents rated moderate-to-high amounts of worry about the impact of COVID-19 on their emotional (46.3%) and physical health (46.7%), and 54.8% endorsed moderate-to-high pandemic-related stress. Adults with diagnosed/suspected mental health disorders or moderate-to-severe NF symptom impact as well as females endorsed higher COVID-19 stress (ps < 0.01). Less than half who missed a doctor's appointment for their NF care (43.4%) used telehealth. Of these, 33.3% and 46.2% reported that telehealth met their needs to a moderate or high degree, respectively. Results indicated that subgroups of adults with NF experience higher COVID-19-related worries and stress and may need additional support. Furthermore, telehealth is under-utilized and could help NF providers connect with patients, although improved delivery and patient training may facilitate expanded use of these services.

"Because the country, it seems though, has turned their back on me": Experiences of institutional betrayal among veterans living with Gulf War Illness.

People living with medically unexplained symptoms (MUS) often have poor quality of life and health outcomes. Many struggle to engage with and trust in healthcare systems. This qualitative study examined how experiences with institutions influence perceptions of medical care for MUS by applying the theoretical framework of institutional betrayal to narratives of U.S. military Veterans living with Gulf War Illness (GWI). Institutional betrayal refers to situations in which the institutions people depend upon for safety and well-being cause them harm. Experiences of institutional betrayal both during active military service and when first seeking treatment appeared to shape perceptions of healthcare in this sample. Veterans expressed the belief that the military failed to protect them from environmental exposures. Veterans' concerns regarding subsequent quality of healthcare were intrinsically linked to a belief that, despite official documentation to the contrary, the predominant paradigm of both the U.S. Department of Defense and the U.S. Department of Veterans Affairs (VA) is that GWI does not exist. Veterans reported that providers are not adequately trained on treatment of GWI and do not believe Veterans' descriptions of their illness. Veterans reported taking up self-advocacy, doing their own research on their condition, and resigning themselves to decrease engagement with VA healthcare or seek non-VA care. The study's findings suggest institutional level factors have a profound impact on perceptions of care and the patient-provider relationship. Future research and policy aimed at improving healthcare for people living with MUS should consider the concept of institutional betrayal.

Validating Techniques for Measurement of Cutaneous Neurofibromas: Recommendations for Clinical Trials.

OBJECTIVE: To assess the reliability and variability of digital calipers, 3D photography, and high-frequency ultrasound (HFUS) for measurement of cutaneous neurofibromas (cNF) in patients with neurofibromatosis type 1 (NF1). BACKGROUND: cNF affect virtually all patients with NF1 and are a major source of morbidity. Reliable techniques for measuring cNF are needed to develop therapies for these tumors. METHODS: Adults with NF1 were recruited. For each participant, 6 cNF were assessed independently by 3 different examiners at 5 different time points using digital calipers, 3D photography, and HFUS. The intraclass correlation coefficient (ICC) was used to assess intrarater and interrater reliability of linear and volumetric measurements for each technique, with ICC values >0.90 defined as excellent reliability. The coefficient of variation (CV) was used to estimate the minimal detectable difference (MDD) for each technique. RESULTS: Fifty-seven cNF across 10 participants were evaluated. The ICC for image acquisition and measurement was >0.97 within and across examiners for HFUS and 3D photography. ICC for digital calipers was 0.62-0.88. CV varied by measurement tool, linear vs volumetric measurement, and tumor size. CONCLUSIONS: HFUS and 3D photography demonstrate excellent reliability whereas digital calipers have good to excellent reliability in measuring cNF. The MDD for each technique was used to create tables of proposed thresholds for investigators to use as guides for clinical trials focused on cNF size. These criteria should be updated as the performance of these end points is evaluated.

Current Recommendations for Patient-Reported Outcome Measures Assessing Domains of Quality of Life in Neurofibromatosis Clinical Trials.

OBJECTIVE: To review and recommend patient-reported outcome (PRO) measures assessing multidimensional domains of quality of life (QoL) to use as clinical endpoints in medical and psychosocial trials for children and adults with neurofibromatosis (NF) type 1, NF2, and schwannomatosis. METHODS: The PRO working group of the Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration used systematic methods to review, rate, and recommend existing self-report and parent-report PRO measures of generic and disease-specific QoL for NF clinical trials. Recommendations were based on 4 main criteria: patient characteristics, item content, psychometric properties, and feasibility. RESULTS: The highest-rated generic measures were (1) the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scales for NF clinical trials for children or for children through adults, (2) the Functional Assessment of Cancer Therapy-General for adult medical trials, and (3) the World Health Organization Quality of Life-BREF for adult psychosocial trials. The highest-rated disease-specific measures were (1) the PedsQL NF1 Module for NF1 trials, (2) the NF2 Impact on Quality of Life Scale for NF2 trials, and (3) the Penn Acoustic Neuroma Quality of Life Scale for NF2 trials targeting vestibular schwannomas. To date, there are no disease-specific tools assessing multidimensional domains of QoL for schwannomatosis. CONCLUSIONS: The REiNS Collaboration currently recommends these generic and disease-specific PRO measures to assess multidimensional domains of QoL for NF clinical trials. Additional research is needed to further evaluate the use of these measures in both medical and psychosocial trials.

Patient Report of Hearing in Neurofibromatosis Type 2: Recommendations for Clinical Trials.

OBJECTIVE: To systematically evaluate published patient-reported outcome measures for the assessment of hearing function and hearing-related quality of life (QoL) and recommend measures selected by the Response Evaluation in Neurofibromatosis and Schwannomatosis International Collaboration (REiNS) as endpoints for clinical trials in neurofibromatosis type 2 (NF2). METHODS: The REiNS Patient-Reported Outcomes Working Group systematically evaluated published patient-reported outcome measures of (1) hearing function and (2) hearing-related QoL for individuals with hearing loss of various etiologies using previously published REiNS rating procedures. Ten measures of hearing functioning and 11 measures of hearing-related QoL were reviewed. Measures were numerically scored and compared primarily on their participant characteristics (including participant age range and availability of normative data), item content, psychometric properties, and feasibility for use in clinical trials. RESULTS: The Self-Assessment of Communication and the Self-Assessment of Communication-Adolescent were identified as most useful for adult and pediatric populations with NF2, respectively, for the measurement of both hearing function and hearing-related QoL. Measures were selected for their strengths in participant characteristics, item content, psychometric properties, and feasibility for use in clinical trials. CONCLUSIONS: REiNS recommends the Self-Assessment of Communication adult and adolescent forms for the assessment of patient-reported hearing function and hearing-related QoL for NF2 clinical trials. Further work is needed to demonstrate the utility of these measures in evaluating pharmacologic or behavioral interventions.

Enhancing Neurofibromatosis Clinical Trial Outcome Measures Through Patient Engagement: Lessons From REiNS.

OBJECTIVE: As part of an evaluation of the Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration patient representative program, we surveyed REiNS members to (1) identify facilitators and barriers to involving patient representatives and (2) understand whether and how involving patient representatives affected recommendations for clinical trial outcomes. METHODS: We administered an anonymous online survey to all REiNS members. Facilitators and barriers to patient representative involvement were solicited using a modified free listing technique; responses were inductively grouped into higher-order categories and ranked based on saliency score (Smith s). Open-ended questions assessed patient representative expectations for engagement, perceived benefits/costs of patient engagement, and patient representative contributions; responses were analyzed using conventional content analysis. RESULTS: A total of 63/172 (37%) members responded, including 18/30 (60%) patient representatives. Providing sufficient opportunities to meaningfully engage in research tasks and cultivating a respectful, inclusive atmosphere were key facilitators to patient representatives' satisfaction and ability to make an impact. Respondents perceived that patient representatives directly (through their input on research tasks) and indirectly (through effects on other stakeholders' knowledge and communication style) improved the organization's research, leading to selection of more meaningful, relevant, and feasible clinical trial outcome measures. Ongoing challenges to patient engagement include difficulty scheduling meetings and concerns about the level of scientific knowledge patient representatives needed to effectively engage. CONCLUSIONS: Involving patient representatives in REiNS improved perceived quality of neurofibromatosis clinical trial outcome measures. Negotiating sufficient opportunities to engage, fostering an inclusive atmosphere, and navigating time pressures are key to effective patient engagement.

The impact of the COVID-19 pandemic on neurofibromatosis clinical care and research.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has had unprecedented impact on the provision of medical care for genetic disorders. The purpose of this study was to assess the effects of the pandemic on neurofibromatosis (NF) care and research. METHODS: Sixty-three United States NF clinics were surveyed to identify the impact of the pandemic on clinician role, patient volume, continuity of guideline-driven surveillance, research protocols, and use of (and satisfaction with) telehealth for the delivery of NF care. RESULTS: Fifty-two clinic directors or their representatives completed the survey (83% response rate). About 2/3 of the clinics reported a greater than 50% decrease in the number of available patient appointments, and modified clinical surveillance and research protocols. Fifty-one clinics (98%) newly instituted telehealth during the pandemic. Barriers to telehealth prior to the pandemic were insurance reimbursement concerns and lack of infrastructure. Since telehealth was initiated, high provider satisfaction was reported with ease of use. The most common area of concern was related to inability to perform a physical examination. CONCLUSION: Results show marked impacts on NF care and research since the beginning of the pandemic, with potential long-term changes related to the introduction (or adoption) of telehealth for clinical care.

Effective provider-patient communication of a rare disease diagnosis: A qualitative study of people diagnosed with schwannomatosis.

OBJECTIVE: To understand diagnostic communication preferences of patients with schwannomatosis, a rare disease. METHODS: Eighteen adults with schwannomatosis from across the United States participated in semi-structured phone interviews about their diagnostic experiences. Interview transcripts were inductively coded using thematic analysis. RESULTS: We identified three elements of effective diagnostic communication: education (particularly about etiology, prognosis, and treatment options); psychological support (to cope with the new diagnosis and any prior diagnostic harms); and efforts to develop therapeutic alliance (i.e. feelings of collaboration, trust, and social-emotional rapport). Poor communication was characterized by inadequate or jargon-heavy explanations, perceived disinterest in or disbelief of symptoms, and lack of partnership. Effective communication helped people feel informed and cope with their condition; poor communication could cause significant psychological distress. CONCLUSIONS: During diagnosis, patients need education and psychosocial support; the presence of therapeutic alliance between clinicians and patients facilitates this assistance. Diagnostic communication that includes these elements helps patients proactively engage in healthcare decision-making and connect with appropriate treatments. PRACTICE IMPLICATIONS: When disclosing a rare disease diagnosis, clinicians should meaningfully educate patients about the disorder and acknowledge diagnosis-related psychosocial stressors. Approaching diagnosis empathetically and collaboratively helps foster therapeutic alliance. Referrals for psychological and genetic counseling are often warranted.

Increasing access to specialty care for rare diseases: a case study using a foundation sponsored clinic network for patients with neurofibromatosis 1, neurofibromatosis 2, and schwannomatosis.

BACKGROUND: Our primary aim was to assess the ability of a non-profit foundation-sponsored clinic network to facilitate access to specialized care for patients with neurofibromatoses (NF), a group of neurogenetic disorders including NF1, NF2, and schwannomatosis (SWN). Our secondary aim was to identify how our findings in NF could be applied more broadly to other rare diseases. METHODS: We retrospectively reviewed aggregate data on patient volume reported by specialty NF clinics in a nonprofit network from 2008 to 2015. We classified clinics as high or low volume for disease type (NF1 and NF2/schwannomatosis) and pediatric/adult care. We compared clinic-level data to self-reported patient-level data from a large online patient registry. RESULTS: Between 2008 and 2015, the number of certified NF clinics grew from 32 to 50, and annual patient volume rose from 6776 to 10,245 patients (13% of the total estimated U.S. NF patient population). For patient registry participants (n = 4476), the median driving distance to the nearest network clinic was 51.3 miles. Driving distances to reach high-volume centers were elevated for adults compared to children (295.8 vs. 67.9 miles), and schwannomatosis and NF2 patients compared to NF1 patients (310.9 vs. 368.1 vs. 161.7 miles). Of registry participants reporting their location of care (n = 2271), only 43.2% received care in a network specialty clinic, with especially low rates of attendance in the Southwest and Far West. CONCLUSIONS: While the number of certified NF clinics and volume of patients seen in these clinics has increased, many NF patients still do not attend specialty clinics and/or travel a significant distance for care. Geographic access to care is more limited for adults, patients with rarer conditions, and patients in the Western U.S. Potential measures to improve access to specialty care for people living with NF and other rare diseases are discussed.

Improvement in Patient-reported Hearing After Treatment With Bevacizumab in People With Neurofibromatosis Type 2.

OBJECTIVE: Assess patient-reported outcomes (PRO) for hearing and tinnitus relative to clinical hearing assessment in people with neurofibromatosis 2 (NF2) associated hearing loss. STUDY DESIGN: Prospective, open label, phase-II clinical trial with PRO administered pre-, post-, and after treatment. SETTING: Three tertiary referral centers. PATIENTS: Fourteen patients with NF2, median age of 30 years (range, 14-79 yr) and progressive hearing loss (median baseline word recognition score, 60%; range, 13-82%). Half of these patients achieved objective hearing response (word recognition score improved beyond the 95% critical difference versus baseline). INTERVENTION: Bevacizumab 7.5 mg/kg was administered every 3 weeks for 48 weeks, followed by surveillance for 24 weeks off-drug. MAIN OUTCOME MEASURES: Speech, spatial, and qualities of hearing scale (SSQ) and tinnitus reaction questionnaire (TRQ) to assess hearing difficulties in life situations and tinnitus related distress. RESULTS: Patient-reported speech understanding and auditory quality improved with bevacizumab treatment and were significantly correlated with word recognition scores, but not pure tone threshold average. There was no change in spatial perception after treatment. Reduction in tinnitus distress after treatment with bevacizumab did not reach statistical significance. CONCLUSION: Participants had reductions in hearing difficulty during treatment with bevacizumab, suggesting that patients subjectively experience hearing-related benefit mirroring clinical hearing assessments. We suspect the lack of significant reduction in tinnitus distress is related to small sample size and low intensity of distress in our sample. These data highlight the usefulness of PRO measures to assess benefits of treatment in the setting of NF2-associated hearing loss.
