Role Attainment in Emerging Adulthood: Subjective Evaluation by Male Adolescents and Adults with Duchenne and Becker Muscular Dystrophy.

BACKGROUND: Youth with Duchenne and Becker muscular dystrophy (DBMD) experience challenges in attaining adult roles, which may impact quality of life. New interventions and treatments may facilitate adult role attainment through improved function. Historical data on adult role attainment is important to assess the impact of new interventions on teens and young adults with DBMD. This study assesses medical knowledge, independence and employment, and relationships among adolescents and young adults with DBMD. METHODS: This study uses data from a 2013 Muscular Dystrophy Surveillance, Tracking, and Research Network (MD STARnet) survey on adult transition. Males with DBMD aged 16-30 years were included. RESULTS: Sixty-five of 258 eligible males participated; we report results on 60 participants with an MD STARnet case definition of DMD or BMD. Individuals with BMD reported higher rates than those with DMD of frequently staying home without supervision (50% BMD; 14% DMD), independently performing daily physical needs (93% BMD; 7% DMD) and being employed full or part time (33% BMD; 4% DMD). Most participants understood medication and physical therapy goals; less than half indicated being often or always responsible for scheduling DMBD-related management and refilling medications. Most had not been in a romantic relationship but reported desiring such relationships. CONCLUSIONS: Our data reinforce the impact of DMD (and to a lesser extent, BMD) on transition to adult roles. These results provide an important historical comparator for teen and adult patients who are trying new interventions and therapies. Such data are important for assessing the quality-of-life impact of new treatments and to inform support and training programs for people with DBMD as they transition to new adult roles and responsibilities.

Current Practices in Treating Cardiomyopathy and Heart Failure in Duchenne Muscular Dystrophy (DMD): Understanding Care Practices in Order to Optimize DMD Heart Failure Through ACTION.

Cardiac disease has emerged as a leading cause of mortality in Duchenne muscular dystrophy in the current era. This survey sought to identify the diagnostic and therapeutic approach to DMD among pediatric cardiologists in Advanced Cardiac Therapies Improving Outcomes Network. Pediatric cardiology providers within ACTION (a multi-center pediatric heart failure learning network) were surveyed regarding their approaches to cardiac care in DMD. Thirty-one providers from 23 centers responded. Cardiac MRI and Holter monitoring are routinely obtained, but the frequency of use and indications for ordering these tests varied widely. Angiotensin converting enzyme inhibitor and aldosterone antagonist are generally initiated prior to onset of systolic dysfunction, while the indications for initiating beta-blocker therapy vary more widely. Seventeen (55%) providers report their center has placed an implantable cardioverter defibrillator in at least 1 DMD patient, while 11 providers (35%) would not place an ICD for primary prevention in a DMD patient. Twenty-three providers (74%) would consider placement of a ventricular assist device (VAD) as destination therapy (n = 23, 74%) and three providers (10%) would consider a VAD only as bridge to transplant. Five providers (16%) would not consider VAD at their institution. Cardiac diagnostic and therapeutic approaches vary among ACTION centers, with notable variation present regarding the use of advanced therapies (ICD and VAD). The network is currently working to harmonize medical practices and optimize clinical care in an era of rapidly evolving outcomes and cardiac/skeletal muscle therapies.

Current state of cardiac troponin testing in Duchenne muscular dystrophy cardiomyopathy: review and recommendations from the Parent Project Muscular Dystrophy expert panel.

Cardiac disease is now the leading cause of death in Duchenne muscular dystrophy (DMD). Clinical evaluations over time have demonstrated asymptomatic cardiac troponin elevations and acute elevations are associated with symptoms and cardiac dysfunction in DMD. Clinicians require a better understanding of the relationship of symptoms, troponin levels and progression of cardiac disease in DMD. As clinical trials begin to assess novel cardiac therapeutics in DMD, troponin levels in DMD are important for safety monitoring and outcome measures. The Parent Project Muscular Dystrophy convened an expert panel of cardiologists, scientists, and regulatory and industry specialists on 16 December 2019 in Silver Spring, Maryland and reviewed published and unpublished data from their institutions. The panel recommended retrospective troponin data analyses, prospective longitudinal troponin collection using high-sensitivity cardiac troponin I assays, inclusion of troponin in future clinical trial outcomes and future development of clinical guidelines for monitoring and treating troponin elevations in DMD.

Conference report on contractures in musculoskeletal and neurological conditions.

Limb contractures are debilitating complications associated with various muscle and nervous system disorders. This report summarizes presentations at a conference at the Shirley Ryan AbilityLab in Chicago, Illinois, on April 19-20, 2018, involving researchers and physicians from diverse disciplines who convened to discuss current clinical and preclinical understanding of contractures in Duchenne muscular dystrophy, stroke, cerebral palsy, and other conditions. Presenters described changes in muscle architecture, activation, extracellular matrix, satellite cells, and muscle fiber sarcomeric structure that accompany or predispose muscles to contracture. Participants identified ongoing and future research directions that may lead to understanding of the intersecting factors that trigger contractures. These include additional studies of changes in muscle, tendon, joint, and neuronal tissues during contracture development with imaging, molecular, and physiologic approaches. Participants identified the requirement for improved biomarkers and outcome measures to identify patients likely to develop contractures and to accurately measure efficacy of treatments currently available and under development.

Practical Considerations in Using Online Modified-Delphi Approaches to Engage Patients and Other Stakeholders in Clinical Practice Guideline Development.

Patients and caregivers are increasingly recognized as key stakeholders in developing clinical practice guidelines (CPGs). Online engagement approaches offer the promise of a rigorous, scalable, and convenient engagement method. This paper illustrates how an online modified-Delphi approach could be used to engage patients, caregivers, and other stakeholder in CPG development. It provides practical guidance for conducting online modified-Delphi panels that covers (1) joint development of the engagement approach with relevant stakeholders, (2) adaptation of methods used by experts in guideline development, (3) pilot testing, (4) participant recruitment, (5) determining panel size and composition, (6) building participant capacity, (7) facilitation of two-way interaction, (8) continuous engagement and retention of participants, (9) rigorous data analysis, (10) evaluation of engagement activities, and (11) result dissemination. The paper is based on a recently completed study about engaging individuals with Duchenne muscular dystrophy (DMD) and their caregivers in determining the patient-centeredness of DMD care guidelines.

Using an Online, Modified Delphi Approach to Engage Patients and Caregivers in Determining the Patient-Centeredness of Duchenne Muscular Dystrophy Care Considerations.

Purpose. To determine the patient-centeredness of endocrine and bone health Duchenne muscular dystrophy (DMD) care considerations using the RAND/PPMD Patient-Centeredness Method (RPM), which is a novel, online, modified-Delphi approach to engaging patients and caregivers in clinical guideline development. Methods. We solicited input on the patient-centeredness of care considerations from 28 individuals with DMD and 94 caregivers, randomly assigned to 1 of 2 mixed panels. During a 3-round online modified-Delphi process, participants rated the importance and acceptability of 19 DMD care considerations (round 1), reviewed and discussed the initial results (round 2), and revised their original ratings (round 3). Patient-centeredness was operationalized as importance and acceptability of recommendations. We considered a care consideration to be patient-centered if both panels deemed it important and acceptable. Results. Ninety-five panelists (78%) participated in this study. Of these, 88 (93%) participated in round 1, 74 (78%) in round 2, and 56 (59%) in round 3. Panelists deemed 12 care considerations to be patient-centered: 3 weight management, 3 bone health, 4 vertical growth, and 2 puberty recommendations. Seven care considerations did not meet patient-centeredness criteria. Common reasons were lack of evidence specific to DMD and concerns about insurance coverage, access to treatment, and patient safety. Conclusions. Using the RPM, Duchenne families considered most care considerations to be patient-centered. Besides being clinically appropriate, these considerations are likely to be consistent with the preferences, needs, and values of Duchenne families. While all relevant care considerations should be discussed during patient-provider encounters, those that did not meet patient-centeredness criteria in particular should be carefully considered as part of joint decision making between Duchenne families and their providers.

Patient and caregiver perspectives on guideline adherence: the case of endocrine and bone health recommendations for Duchenne muscular dystrophy.

BACKGROUND: Clinical care guidelines are typically developed by clinicians and researchers. Including patient and caregiver voices in guideline development may help create guidelines that are more useful for patients and consequently improve their guideline adherence. Although there is substantial research on the factors the affect providers' adherence to guidelines, there is less research on the factors that affect patients' compliance with guideline recommendations, especially among those with rare disorders. The purpose of this study is to explore factors that are likely to affect patient/caregiver adherence to endocrine and bone health recommendations for Duchenne Muscular Dystrophy (DMD). To do so, we used qualitative data collected as part of the study designed to develop, implement, and evaluate a new online, modified-Delphi approach to engaging patients with rare diseases and their caregivers in guideline development, using care guidelines for DMD as a case study. METHODS: We thematically analyzed qualitative data collected from 95 adults with DMD and their caregivers who participated in at least one round of our online Modified-Delphi panel process. Participants rated and commented on the patient-centeredness of 19 recommendations about vertical growth, weight management, bone health, and delayed puberty included in the 2018 DMD care considerations. Patient-centeredness was operationalized as the importance and acceptability of care recommendations. RESULTS: Thematic analyses revealed six factors that affect guideline adherence from the patient/caregiver perspective: content and format of recommendations, patient and provider characteristics, and social and financial factors. CONCLUSIONS: This study used a novel approach to exploring patient and caregiver perspectives on factors that may affect guideline adherence. The six factors identified by DMD patients and caregivers are similar to the factors affecting provider adherence and are not limited to DMD. Understanding consistency between provider- and patient/caregiver-identified barriers to following guideline recommendations can lead to developing more successful interventions for increasing guideline adherence.

Management of Adrenal Insufficiency Risk After Long-term Systemic Glucocorticoid Therapy in Duchenne Muscular Dystrophy: Clinical Practice Recommendations.

Long-term glucocorticoid therapy has improved outcomes in patients with Duchenne muscular dystrophy. However, the recommended glucocorticoid dosage suppresses the hypothalamic-pituitary-adrenal axis, leading to adrenal insufficiency that may develop during severe illness, trauma or surgery, and after discontinuation of glucocorticoid therapy. The purpose of this review is to highlight the risk of adrenal insufficiency in this patient population, and provide practical recommendations for management of adrenal insufficiency, glucocorticoid withdrawal, and adrenal function testing. Strategies to increase awareness among patients, families, and health care providers are also discussed.

Unique Burdens of Pediatric Clinical Trials in Duchenne Muscular Dystrophy, April 20-21, 2017, Bethesda, Maryland, USA.

Recent increases in the number and breadth of clinical trials for patients with Duchenne muscular dystrophy (DMD) have engendered hope for a better future. Despite the overall enthusiasm by the DMD community for these trials, however, the burdens and pressures that they place on children with Duchenne muscular dystrophy and their families have become painfully apparent. In order to identify, and mediate, these challenges, Parent Project Muscular Dystrophy (PPMD) sponsored a meeting to examine some of these issues more closely in Bethesda, Maryland, on April 20-21, 2017. The meeting focused on key burdens for patients participating in clinical trials including technical (protocol complexity), financial, psychosocial and emotional issues, and informed consent. Participants recommended mitigation strategies falling into clinical, operations, regulatory, and ethical domains. The development of consensus action plans for short- and long-term enhancements in trials should facilitate discovery and development research for DMD patients.

Participant experiences with a new online modified-Delphi approach for engaging patients and caregivers in developing clinical guidelines.

BACKGROUND: Patient engagement in clinical practice guideline (CPG) development has increased significantly in recent years. However, only a few patients and caregivers join CPG development groups. OBJECTIVE: To describe participant experiences with a novel online, scalable approach for patient and caregiver engagement in CPG development. DESIGN: We developed and tested the RAND/PPMD Patient-Centeredness Method (RPM), a novel online modified-Delphi approach to patient engagement in CPG development that consists of an optional idea generation round and two rating rounds interspersed with an online discussion round. SETTING AND PARTICIPANTS: Using the online ExpertLens™ system, we ran 2 concurrent panels of patients and caregivers of individuals with Duchenne Muscular Dystrophy (DMD). MAIN OUTCOME MEASURES: We surveyed all 95 panel participants about their participation and satisfaction with the process. We also conducted telephone interviews with 25 participants. RESULTS: Participants expressed satisfaction with various ExpertLens™ features, noting that the system fostered lively interaction among them. Panelists also appreciated participating in an educational, interactive and convenient discussion forum that allowed them to share their opinions on the importance and acceptability of different recommendations. The RPM was viewed as empowering by patients and their caregivers who felt it would be useful for CPG developers. DISCUSSION AND CONCLUSION: The results of our study show the overall participant satisfaction with a novel, scalable, online approach to engaging patients and caregivers in CPG development, which allows them to share their perspectives and lived experiences using a rigorous, systematic and iterative way that is similar to how clinicians provide their input.

The RAND/PPMD Patient-Centeredness Method: a novel online approach to engaging patients and their representatives in guideline development.

Although clinical practice guidelines (CPGs) provide recommendations for how best to treat a typical patient with a given condition, patients and their representatives are not always engaged in CPG development. Despite the agreement that patient participation may improve the quality and utility of CPGs, there is no systematic, scalable method for engaging patients and their representatives, as well as no consensus on what exactly patients and their representatives should be asked to do during CPG development. To address these gaps, an interdisciplinary team of researchers, patient representatives, and clinicians developed the RAND/PPMD Patient-Centeredness Method (RPM) - a novel online approach to engaging patients and their representatives in CPG development. The RPM is an iterative approach that allows patients and their representatives to provide input by (1) generating ideas; (2) rating draft recommendations on two criteria (importance and acceptability); (3) explaining and discussing their ratings with other participants using online, asynchronous, anonymous, moderated discussion boards, and (4) revising their responses if needed. The RPM was designed to be consistent with the RAND/UCLA Appropriateness Method used by clinicians and researchers to develop CPG, while helping patients and their representative rate outcome importance and recommendation acceptability - two key components of the GRADE Evidence to Decision (EtD) framework. With slight modifications, the RPM has the potential to explore consensus among key stakeholders on other dimensions of the EtD, including feasibility, equity, and resource use.

Cardiac Management of the Patient With Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) results in a progressive cardiomyopathy that produces significant morbidity and mortality. To improve the quality of life in patients with DMD, cardiac care is focused on surveillance and management, with the goal of slowing the onset and progression of heart failure complications. The current article is intended to be an expanded review on the cardiac management data used to inform the 2018 DMD Care Considerations recommendations as well as be a discussion on clinical controversies and future management directions. The new cardiac guidance includes changes regarding noninvasive imaging surveillance of cardiac function and pharmacologic therapy. Many emerging therapies lack sufficient evidence-based data to be recommended in the 2018 DMD Care Considerations. These are discussed in the present article as clinical controversies and future directions. Important emerging therapies include new heart failure medications, mechanical circulatory support with ventricular assist devices, heart transplantation, and internal cardiac defibrillators. Future research studies should be focused on the risks and benefits of these advanced therapies in patients with DMD. We conclude this review with a brief discussion on the relationship between the heart and the recently developed medications that are used to directly target the absence of dystrophin in DMD.

Primary Care and Emergency Department Management of the Patient With Duchenne Muscular Dystrophy.

Primary care providers (PCPs) are usually the first point of contact with the health care system for patients with Duchenne muscular dystrophy (DMD), and patients often present to emergency departments in which providers have little experience in dealing with this condition. With this article, we give primary care and emergency medicine providers a background in the common issues that affect people with DMD. By acquiring some specialized knowledge about the multisystem medical complications of DMD and by applying general principles of primary care, such as timely immunization, anticipatory safety counseling, behavioral screening, and routine nutritional and developmental assessments, the PCP can be a valued and effective medical provider to patients with DMD. The PCP can provide access to and effective coordination among the patient's specialty caregivers. Moreover, the PCP can become a trusted advisor to the patient and his family about important medical decisions, as well as issues in the psychosocial, behavioral, and educational domains. This article also contains a "pocket guide" used to assess and manage common urgent medical problems that cause patients with DMD to seek care in the emergency department. With the background information discussed in this article, both PCPs and emergency medicine physicians can skillfully care for patients with DMD in their respective settings, optimizing patient outcomes.

Psychosocial Management of the Patient With Duchenne Muscular Dystrophy.

In this article, we outline a comprehensive plan for the psychosocial management of patients with Duchenne muscular dystrophy (DMD) across the life span. In 2010, the Centers for Disease Control and Prevention sponsored the development of multidisciplinary management guidance for DMD, and in 2018, that guidance was updated. In the intervening years, a new emphasis was placed on studying and addressing the psychosocial issues that affect patients with DMD, driven in part by improved patient survival. Once viewed as ancillary to managing the significant medical needs of patients with DMD, it is now standard practice to integrate psychosocial management into the multidisciplinary management of the disease. It is also increasingly recognized that neurodevelopmental disorders in DMD occur at a higher rate than what was previously understood and that these disorders warrant early and intensive intervention. In this article, we expand on the content found in the 2018 DMD Care Considerations.

Evaluating Implementation of the Updated Care Considerations for Duchenne Muscular Dystrophy.

Care Considerations for Duchenne Muscular Dystrophy were published in 2010. However, little is known about the extent to which these considerations were implemented after publication. With this article, we provide direction on evaluating the uptake of the 2018 Duchenne Muscular Dystrophy Care Considerations. We identify key elements of care and present suggestions for their use in evaluation and research.

Health Care Transition Experiences of Males with Childhood-onset Duchenne and Becker Muscular Dystrophy: Findings from the Muscular Dystrophy Surveillance Tracking and Research Network (MD STARnet) Health Care Transitions and Other Life Experiences Survey.

Introduction: As the proportion of males with Duchenne muscular dystrophy (DMD) surviving into adulthood increases, more information is needed regarding their health care transition planning, an essential process for adolescents and young adults with DMD. The objective of this study was to describe the health care transition experiences of a population of males living with Duchenne or Becker muscular dystrophy (DBMD). Methods: The eligible participants, identified through the Muscular Dystrophy Surveillance Tracking and Research Network (MD STARnet) surveillance project, were 16-31 years old and lived in Arizona, Colorado, Georgia, Iowa, or western New York (n=258). The MD STARnet Health Care Transitions and Other Life Experiences Survey was conducted in 2013 and administered online or in a telephone interview. Sixty-five males (25%) completed the survey. Among non-ambulatory males, response differences were compared by age group. Statistical comparisons were conducted using Fisher's exact test, or when appropriate, the Chisquare test. Results: Twenty-one percent of non-ambulatory males aged 16-18 years, 28% of non-ambulatory males aged 19-23 years, 25% of non-ambulatory males aged 24-30 years, and 18 ambulatory males had a written transition plan. Nineteen percent of non-ambulatory males aged 24-30 years had delayed or gone without needed health care in the past 12 months. Among non-ambulatory males aged 24-30 years, 75% had cardiology providers and 69% had pulmonology providers involved in their care in the past 12 months. Twentyeight percent of non-ambulatory males aged 19-23 years and 25% of non-ambulatory males aged 24-30 years reported that they did not receive health care or other services at least once because they were unable to leave their home. Non-ambulatory males aged 16-18 years (29%) were less likely to have ever discussed how to obtain or keep health insurance as they get older compared to non-ambulatory males aged 24-30 years (69%) (p <0.01). Discussion: This study identified potential barriers to the successful health care transition of males with DBMD. The results of this study may indicate a lack of targeted informational resources and education focused on supporting the transition of young men with DBMD as they age from adolescence into adulthood within the healthcare system. Future studies could determine the reasons for the potential barriers to health care and identify the optimal transition programs for males with DBMD. There are a few online resources on transition available to adolescents and young adults with special health care needs.

Collective Statement Regarding Patient Access to Approved Therapies from the Center Directors of Parent Project Muscular Dystrophy's Certified Duchenne Care Centers.

The dystrophinopathies (Duchenne [DMD] and Becker muscular dystrophy) are progressive diseases that until recently had no specific treatments. New FDA pathways to drug approval in rare diseases have resulted in a dramatic increase in the number of treatment trials for DMD and recently, two approved drugs. Health insurance policies for DMD products have been constructed with limited input from neuromuscular specialists directly involved in patient care and without patient input. These policies often reflect a lack of understanding of the disease, clinical population or the treatment. To ensure that policy determinations reflect best clinical practice, we recommend insurers work with neuromuscular specialists with expertise in care for patients with dystrophinopathy, as well as patients and families, and prominent advocacy organizations, such as Parent Project Muscular Dystrophy, in developing policies.

Diagnosis and management of Duchenne muscular dystrophy, part 3: primary care, emergency management, psychosocial care, and transitions of care across the lifespan.

Improvements in the function, quality of life, and longevity of patients with Duchenne muscular dystrophy (DMD) have been achieved through a multidisciplinary approach to management across a range of health-care specialties. In part 3 of this update of the DMD care considerations, we focus on primary care, emergency management, psychosocial care, and transitions of care across the lifespan. Many primary care and emergency medicine clinicians are inexperienced at managing the complications of DMD. We provide a guide to the acute and chronic medical conditions that these first-line providers are likely to encounter. With prolonged survival, individuals with DMD face a unique set of challenges related to psychosocial issues and transitions of care. We discuss assessments and interventions that are designed to improve mental health and independence, functionality, and quality of life in critical domains of living, including health care, education, employment, interpersonal relationships, and intimacy.
