Abstract
INTRODUCTION Onasemnogene abeparvovec (OA) is the only gene replacement therapy currently approved for spinal muscular atrophy (SMA) treatment. We sought to assess real-world patient and caregiver outcomes after OA treatment for SMA. METHODS Patients who received OA were identified from the 2021 Cure SMA Membership Survey. Those treated at 6-23 months of age were matched to non-patients treated with OA on the basis of age at the time of survey and survival motor neuron 2 gene copy number. Patient characteristics, motor milestones, and resource and supportive care use, as well as caregiver proxy-reported health-related quality of life (HRQOL), were described. Caregiver unmet needs and HRQOL were also assessed. RESULTS Of the 614 patients in the survey, 64 received OA, and 17 were matched with 28 non-OA-treated patients. In general, a greater percentage of OA-treated patients achieved various motor milestones, including 100% sitting without support and 58.8% walking with assistance. OA-treated patients also had numerically lower rates of hospitalization and surgery. None required tracheostomy with a ventilator. The rate of using oxygen or a breathing machine for more than 16 h was also lower for OA-treated patients. OA-treated patients had less frequent trouble swallowing. HRQOL was reported to be similar to non-OA-treated patients. Caregivers of OA-treated patients reported better patient mobility scores and less work impairment. CONCLUSIONS The study suggests that treatment with OA is associated with greater rates of motor milestone achievements and less resource and supportive care use for patients with SMA treated at 6-23 months of age in the real world. For caregivers, it may also potentially reduce unmet needs, improve HRQOL, and reduce work impairment.

Abstract
BACKGROUND AND OBJECTIVES Motor Neuron Diseases (MND) are rare diseases but have a high impact on affected individuals and society. This study aims to perform an economic evaluation of MND in Germany. METHODS Primary patient-reported data were collected including individual impairment, the use of medical and non-medical resources, and self-rated Health-Related Quality of Life (HRQoL). Annual socio-economic costs per year as well as Quality-Adjusted Life Years (QALYs) were calculated. RESULTS 404 patients with a diagnosis of Amyotrophic Lateral Sclerosis (ALS), Spinal Muscular Atrophy (SMA) or Hereditary Spastic Paraplegia (HSP) were enrolled. Total annual costs per patient were estimated at 83,060€ in ALS, 206,856€ in SMA and 27,074€ in HSP. The main cost drivers were informal care (all MND) and disease-modifying treatments (SMA). Self-reported HRQoL was best in patients with HSP (mean EuroQoL Five Dimension Five Level (EQ-5D-5L) index value 0.67) and lowest in SMA patients (mean EQ-5D-5L index value 0.39). QALYs for patients with ALS were estimated to be 1.89 QALYs, 23.08 for patients with HSP and 14.97 for patients with SMA, respectively. Cost-utilities were estimated as follows: 138,960€/QALY for ALS, 525,033€/QALY for SMA, and 49,573€/QALY for HSP. The main predictors of the high cost of illness and low HRQoL were disease progression and loss of individual autonomy. CONCLUSION As loss of individual autonomy was the main cost predictor, therapeutic and supportive measures to maintain this autonomy may contribute to reducing high personal burden and also long-term costs, e.g., care dependency and absenteeism from work.

Abstract
Introduction Spinal muscular atrophy (SMA) is a rare neuromuscular disease requiring various clinical specialists and therapists to provide care. Due to the disease's dynamic nature and the long distances between specialized centers and local providers, integrating care between disciplines can be challenging. Care that is inadequately integrated can compromise the quality of care and become a burden for patients and families. This trial aimed to improve the care of patients through a case management (CM) intervention. Methods We conducted an exploratory, controlled, two-arm trial with pre-, post-, and follow-up measures (process and outcome evaluation). Proof of efficacy based on statistical significance was not our primary study objective since we were investigating a rare disease. Primary outcomes were caregivers' HRQoL and caregiver-rated quality of care integration. Our secondary outcome was the children's HRQoL. Results Questionnaires and semi-structured interviews yielded heterogeneous results depending on caregivers' level of experience and desire (or possibility) to delegate care tasks. Discussion Despite differing perceptions, all participants supported the establishment of a care coordination model. We recommend CM immediately after diagnosis to provide the greatest benefit to families. We hope that our trial will support the further development of CM interventions that can be customized for specific diseases.

Abstract
Bulbar function in spinal muscular atrophy has been defined as the ability to meet nutritional needs by mouth while maintaining airway protection and communicate verbally. The effects of disease-modifying treatment on bulbar function are not clear. A multidisciplinary team conducted post-hoc analyses of phase 3 SPR1NT trial data to evaluate bulbar function of infants at risk for spinal muscular atrophy who received one-time gene replacement therapy (onasemnogene abeparvovec) before symptom onset. Three endpoints represented adequate bulbar function in SPR1NT: (1) absence of physiologic swallowing impairment, (2) full oral nutrition, and (3) absence of adverse events indicating pulmonary instability. Communication was not assessed in SPR1NT. We descriptively assessed numbers/percentages of children who achieved each endpoint and all three collectively. SPR1NT included infants <6 postnatal weeks with two (n = 14) or three (n = 15) copies of the survival motor neuron 2 gene. At study end (18 [two-copy cohort] or 24 [three-copy cohort] months of age), 100% (29/29) of patients swallowed normally, achieved full oral nutrition, maintained pulmonary stability, and achieved the composite endpoint. When administered to infants before clinical symptom onset, onasemnogene abeparvovec allowed children at risk for spinal muscular atrophy to achieve milestones within published normal ranges of development and preserve bulbar function.

Abstract
BACKGROUND Children with medical complexity (CMC) require long-term care accompanied by different health- and social care professionals. Depending on the severity of the chronic condition, caregivers spend a lot of time coordinating appointments, communicating between providers, clarifying social legal issues, and more. Effective care coordination is seen as key to addressing the fragmented care that CMC and their families often face. Spinal muscular atrophy (SMA) is a rare genetic, neuromuscular disease which care involves drug therapy and supportive treatment. We examined the care coordination experiences through a qualitative interview analysis of n = 21 interviews with caregivers of children with SMA I or SMA II. RESULTS The code system consists of 7 codes and 12 sub-codes. "Disease and coordination management of the caregivers" describes the management of coordination-related illness demands. "General conditions of care" include enduring organizational aspects of the care network. "Expertise and skills" refers to both parent and professional expertise. "Coordination structure" describes the assessment of existing coordination mechanisms as well as the need for new ones. "Information exchange" defines the information exchange between professionals and parents as well as the exchange of parents among themselves and the perceived exchange between professionals. "Role distribution in care coordination" summarizes parents' "distribution" of coordinative roles among care network actors (including their own). "Quality of relationship" describes the perceived quality of the relationship between professionals and family. CONCLUSION Care coordination is influenced peripherally (e.g., by general conditions of care) and directly (e.g., by coordination mechanisms, interaction in the care network). Access to care coordination appears to be dependent on family circumstances, geographic location, and institutional affiliation. Previous coordination mechanisms were often unstructured and informal. Care coordination is frequently in the hands of caregivers mainly as the care network's interface. Coordination is necessary and must be addressed on an individual basis of existing resources and family barriers. Existing coordination mechanisms in the context of other chronic conditions could also work for SMA. Regular assessments, centralized shared care pathways, and staff training and empowerment of families for self-management should be central components of all coordination models.

Abstract
OBJECTIVE This article estimates the disease burden of 5q-SMA in Colombia by using the Disability-Adjusted Life Years (DALYs) metric. METHODS Epidemiological data were obtained from local databases and medical literature and were adjusted in the DisMod II tool. DALYs were obtained by adding years of life lost due to premature death (YLL) and years lived with disability (YLD). RESULTS The modeled prevalence of 5q-SMA in Colombia was 0.74 per 100,000 population. The fatality rate for all types was 14.1%. The disease burden of 5q-SMA was estimated at 4,421 DALYs (8.6 DALYs/100,000), corresponding to 4,214 (95.3%) YLLs and 207 (4.7%) YLDs. Most of the DALYs were accounted in the 2-17 age group. Of the total burden, 78% correspond to SMA type 1, 18% to type 2, and 4% to type 3. CONCLUSIONS Although 5q-SMA is a rare disease, it is linked to a significant disease burden due to premature mortality and severe sequelae. The estimates shown in this article are important inputs to inform public policy decisions on how to ensure adequate health service provision for patients with 5q-SMA.

Abstract
Spinal muscular atrophy (SMA) is a neurodegenerative disorder that is characterized by progressive weakness, respiratory insufficiency, and dysphagia. Due to symptom burden and disease progress, its care management and impact on daily life can severely burden the families of affected children. The objectives of this study are (1) to explore the health care experiences and (2) to investigate the psychosocial needs of the parents of children with SMA. In total, 29 parents of patients with SMA participated in our study. All children received supportive therapy (e.g., physiotherapy) and most were dependent on medical equipment. Parents perceived the health care positively regarding team quality, communication and access to medical care. An assessment of the impact of the child's health on the family (e.g., stressors, burden, consequences) is not routinely integrated into care. On average, parents reported low to medium levels of psychosocial needs. Due to the complex health care needs of SMA patients, the health care experiences of parents can provide relevant information on care delivery. To enhance the inclusion of psychosocial and emotional issues, as well as family impact, into routine health care, health care providers should be sensitive towards parental needs for consistency in the health care team and emotional aspects and, if applicable, address them proactively.

Abstract
OBJECTIVE The objective of our study was to review, synthesize, and grade published evidence of caregiver burden of spinal muscular atrophy (SMA), a rare autosomal-recessive neuromuscular disease. METHODS We searched Embase and PubMed for full-text articles published from inception up until 28 February, 2022, reporting results from studies of caregiver burden (i.e., negative aspects of providing informal care) in SMA. Two investigators independently screened article titles and abstracts for eligibility, reviewed full-text versions of selected records, extracted the data, and assessed risk of bias using the Newcastle-Ottawa Scale. The evidence was synthesized to answer the following questions: (1) In which geographical settings have the caregiver burden of SMA been studied? (2) What aspects of the caregiver burden of SMA have been investigated? (3) What instruments have been used to measure the caregiver burden of SMA? (4) What is known of the caregiver burden of SMA? (5) How is the caregiver burden of SMA impacted by available disease-modifying drugs? RESULTS We identified 15 publications, covering samples from a total of ten countries (i.e., Australia, Canada, China, France, Germany, Romania, Spain, Turkey, the UK, and the USA), reporting estimates of caregiver burden derived using data recorded via surveys or interviews. The most common instruments used to measure caregiver burden were the Zarit Caregiver Burden Interview, the EQ-5D-5L, and the PedsQL Family Impact Model. Caregiving in SMA was found to be associated with reduced health-related quality of life, impaired family function, depression and anxiety, strain, and stress, as well as a substantial impact on work life and productivity. Evidence of the impact of disease-modifying drugs on caregiver burden in SMA was scarce. CONCLUSIONS Caregivers to patients with SMA were found to be subject to a significant burden, including impaired health-related quality of life, reduced work ability and productivity, and financial stress, and many devote a substantial proportion of their time to provide informal care. Yet, the current body of literature is relatively scarce and more research is needed to better understand the clinical implications of informal caregiving in SMA and the relationship between caregiver burden and SMA types, as well as the impact of new disease-modifying treatments. Our synthesis will be helpful in informing clinical and social support programs (e.g., the routine screening of depression among caregivers, as well as financial support schemes to help manage the long-term day-to-day care) directed towards families caring for patients with SMA.

Abstract
Spinal muscular atrophy (SMA) is a disabling disease that affects not only the patient’s health-related quality of life (HRQoL), but also causes a high caregiver burden (CGB). The aim of this study was to evaluate HRQoL, CGB, and their predictors in SMA. In two prospective, cross-sectional, and multi-center studies, SMA patients (n = 39) and SMA patient/caregiver couples (n = 49) filled in the EuroQoL Five Dimension Five Level Scale (EQ-5D-5L) and the Short Form Health Survey 36 (SF-36). Caregivers (CGs) additionally answered the Zarit Burden Interview (ZBI) and the Hospital Anxiety and Depression Scale (HADS). Patients were clustered into two groups with either low or high HRQoL (EQ-5D-5L index value <0.259 or >0.679). The latter group was mostly composed of ambulatory type III patients with higher motor/functional scores. More severely affected patients reported low physical functioning but good mental health and vitality. The CGB (mean ZBI = 22/88) correlated negatively with patients’ motor/functional scores and age. Higher CGB was associated with a lower HRQoL, higher depression and anxiety, and more health impairments of the CGs. We conclude that patient and CG well-being levels interact closely, which highlights the need to consider the health of both parties while evaluating novel treatments.

Patients with Spinal Muscular Atrophy Type 1 Achieve and Maintain Bulbar Function Following Onasemnogene Abeparvovec Treatment. J Neuromuscul Dis 2023; 10:531-540. [PMID: 37092232 PMCID: PMC10357176 DOI: 10.3233/jnd-221531] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/31/2023] [Indexed: 04/25/2023]
Abstract
BACKGROUND Improvement and maintenance of bulbar function are goals of disease-modifying treatments for spinal muscular atrophy (SMA). Lack of standardized measures and a widely accepted definition of bulbar function represents a gap in SMA care. OBJECTIVE A multidisciplinary team conducted post-hoc analyses of pooled data from one phase 1 (START) and two phase 3 (STR1VE-US, STR1VE-EU) studies to define and evaluate bulbar function of infants with SMA type 1 after receiving one-time gene replacement therapy, onasemnogene abeparvovec. METHODS We defined bulbar function as the ability to meet nutritional needs while maintaining airway protection and the ability to communicate verbally. Four endpoints represented adequate bulbar function: (1) absence of clinician-identified physiologic swallowing impairment, (2) receiving full oral nutrition, (3) absence of adverse events indicating pulmonary instability, and (4) the ability to vocalize at least two different, distinct vowel sounds. We descriptively assessed numbers/percentages of patients who achieved each endpoint and all four collectively. Patients were followed until 18 months old (STR1VE-US and STR1VE-EU) or 24 months (START) post-infusion. RESULTS Overall, 65 patients were analyzed for swallowing, nutrition intake, and adverse events, and 20 were analyzed for communication. At study end, 92% (60/65) of patients had a normal swallow, 75% (49/65) achieved full oral nutrition, 92% (60/65) had no evidence of pulmonary instability, 95% (19/20) met the communication endpoint, and 75% (15/20) achieved all four bulbar function components in the composite endpoint. CONCLUSIONS In these three clinical trials, patients with SMA type 1 who received onasemnogene abeparvovec achieved and maintained the bulbar function criteria utilized within this investigation.

The Role of Associations in Reducing the Emotional and Financial Impact on Parents Caring for Children with Duchenne Muscular Dystrophy: A Cross-Cultural Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:12334. [PMID: 36231658 PMCID: PMC9566307 DOI: 10.3390/ijerph191912334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 09/21/2022] [Accepted: 09/24/2022] [Indexed: 06/16/2023]
Abstract
Caregivers' emotions and finances are affected by the deterioration of functional capacity of patients with Duchenne muscular dystrophy (DMD), both in Mexico and Spain. Patient associations may reduce this impact on caregivers. This study aims to study the role of two models of associations, inspired by two different cultural models, in how the services they provide can help decrease the emotional and financial impact on the caregivers of children with DMD. The sample consisted of 34 caregivers from Mexico and 40 from Spain recruited from Spanish hospitals and rare disease organizations in Spain and Mexico. The instruments used consisted of a sociodemographic and socioeconomic questionnaire, the CarerQol-7D, the PHQ-15, the Zarit Caregiver's Burden Scale and the SWLS. The results showed that caregivers in Mexico are in better physical and psychological health than caregivers in Spain. They also receive more subsidies than those in Spain. Caregivers in Mexico have a greater well-being and are less affected by the economic impact of the disease due to the associations' day-to-day work and the fact that they generate a network of health services that they make available to the patient free of charge. These differences may also be attributable to cultural issues and to the fact that Mexico has a deeply established culture of support.

Abstract
OBJECTIVE In utero SMA treatment could improve survival & neurologic outcomes. We investigated the attitudes of patients and parents with SMA regarding prenatal diagnosis, fetal therapies, and clinical trials. METHODS A multidisciplinary team designed a questionnaire that Cure SMA electronically distributed to parents and patients (>18 years old) affected by SMA. Multivariable ordinal logistic regression was used to analyze associations between respondent characteristics and attitudes. RESULTS Of 114 respondents (60% of whom were patients), only 2 were prenatally diagnosed. However, 91% supported prenatal testing and 81% felt there had been a delay in their diagnosis. Overall, 55% would enroll in a phase I trial for fetal antisense oligonucleotide (ASO) while 79% would choose an established fetal ASO/small molecule therapy. Overall, 61% would enroll in fetal gene therapy trials; 87% would choose fetal gene therapies. Patients were less likely to enroll in a fetal gene therapy trial than parents enrolling a child (OR 0.31, p<0.05). Older parental age and believing there had been excessive delay in diagnosis were associated with an interest in enrolling in a fetal ASO trial (OR 1.04, 7.38, respectively, p<0.05). CONCLUSION In utero therapies are promising for severe genetic diseases. Patients with SMA and their parents view prenatal testing and therapies positively, with gene therapy being favored.

Parents as informal caregivers of children and adolescents with spinal muscular atrophy: a systematic review of quantitative and qualitative data on the psychosocial situation, caregiver burden, and family needs.

Abstract
BACKGROUND Spinal muscular atrophy (SMA) is a rare degenerative neuromuscular disease, mostly occurring in infants and children, leading to muscle wasting and weakness, and premature death. Due to new developments of multiple disease-modifying treatments within the last years, the interest of research in patients affected by SMA increased steadily. However, the psychosocial situation of parents as informal caregivers is still rarely addressed. OBJECTIVES This review aims to highlight quantitative and qualitative data about the psychosocial situation, caregiver burden, and needs of parents as informal caregivers for children and adolescents with SMA. METHODS A systematic literature review was performed including quantitative and qualitative original studies focusing on different psychosocial aspects and outcomes for parents of children and adolescents < 21 years of age with SMA type I-IV (PROSPERO; registration number CRD42020219020). We searched the following databases in November 2020 with a research update in August 2021: MEDLINE, CINAHL, PsycINFO and Web of Science. RESULTS In total, 24 articles from 23 studies were selected for inclusion (15 quantitative studies, 7 articles from 6 qualitative studies, 2 mixed methods studies). The synthesis of included studies shows multiple sources of psychosocial burden for parents of children and adolescents affected by SMA: Most studies found reduced levels of quality of life, moderate to high levels of caregiver burden and distress, as well as physical and mental health symptoms. Further, findings indicate several unmet family needs regarding information, care coordination, treatment decisions, financial support, and adequate supportive care services. CONCLUSION Parents of children and adolescents with SMA face multiple sources of psychosocial stressors, caregiver burden and various unmet family needs. To unburden families, the needs of parents as caregivers should be included in integrated care paths for SMA to improve their psychosocial situation and thus their ability to care for their children and to treat or prevent physical and mental health problems due to overburdening. Future research should focus not only on quality of life and on caregiving-related burden but should also examine the clinical relevance of reported symptoms to support the implementation of adequate support services for families affected by SMA.

Abstract
Background Spinal Muscular Atrophy (SMA) is a rare, recessively inherited neuromuscular disorder that causes progressive muscle weakness. There is a low degree of awareness about SMA amongst the public and healthcare providers, which may impact the perception of the disease and its proper management. To understand how this lack of awareness may have affected diagnosis, care and support for SMA patients and their caregivers, this study aims to investigate the impact of SMA on the lives and daily activities of SMA patients and their caregivers in Malaysia. Methods Nationwide recruitment was carried out via invitations coordinated by a local SMA advocacy organization. A mixed method cross-sectional study consisting of a self-administered questionnaire followed by in-depth interviews (IDIs) and focus group discussions (FGDs) was conducted. The interview sessions were audio-taped, and verbatim transcripts analyzed thematically. Results Participants reported feeling stressed, anxious and depressed. There were issues with delayed diagnosis, lack of information from healthcare professionals about the disease progression, and limited access to supportive services like physiotherapy. Participants expressed their concerns living with self-doubt and turmoil with having to modify their lifestyles, relationships with family and friends, and challenges with educational and career opportunities. Various themes of their hopes for the future touched on having access to treatment, clinical trials, holistic care for symptom management, as well as improving infrastructure for disability access. Conclusion This study, to the best of our knowledge represents the first comprehensive study on SMA in South East Asia, highlights a plethora of issues and challenges experienced by persons with spinal muscular atrophy (PWSMA) and their caregivers in Malaysia, from the point of SMA diagnosis and throughout the management of care, in addition to the deep psychosocial impact of living with SMA. The significant findings of this study may contribute to a better understanding among stakeholders to make improvements in clinical practice, the education system, the work environment as well as holistic care support and society at large.

Abstract
BACKGROUND Spinal muscular atrophy (SMA) is a severe neuromuscular disease that is inherited in an autosomal recessive manner with an estimated incidence of 1 in 10,000 live births. The traditional classification of SMA includes five types (Types 0-4 SMA) based on patient age at disease onset and the highest motor milestone achieved. Spinal muscular atrophy leads to progressive muscle denervation, skeletal muscle atrophy and loss of motor function and ambulation, though phenotypes vary along a disease continuum. Regardless of disease severity, or access to treatment, a multidisciplinary approach to care is required to ease the burden of disease. To date, limited global data exist regarding the cost and resource use associated with SMA management. OBJECTIVE We planned to perform a systematic literature review to identify studies on cost and healthcare resource use associated with SMA. METHODS A comprehensive search was conducted in 2019 using several electronic databases in addition to supplementary sources and updated in 2021 in order to capture recently published studies. Electronic searches performed in Embase, MEDLINE, Evidence-Based Medicine Reviews and EconLit via the Ovid platform were supplemented by searches of the grey literature (reference lists, conference proceedings, global Health Technology Assessment body websites and other relevant sources). Study eligibility criteria were based on the population, interventions, comparators and outcomes (PICO) framework. Quality assessment of full-text publications was evaluated with reference to a published checklist. To accommodate heterogeneity across studies including countries, currencies, populations, time units and methods of reporting used, costs were reported in Euros in 2019. RESULTS A total of 51 publications, comprising 49 unique studies of patients with SMA that met all eligibility criteria were included in the final selection. The publications comprised data from 14 countries and seven additional studies that reported multi-national data. Because of the heterogeneity between the different types of SMA, data were frequently reported separately for individuals with Type 1 or early-onset SMA and for Types 2, 3, and 4 SMA or later-onset SMA. Generally, direct medical costs and resource use were reported to be highest for patients with Type 1 SMA, decreasing incrementally for patients with Type 2 and Type 3 disease. Where cost categories were similar, direct costs were much lower in Europe than in the USA. Indirect costs were primarily associated with informal care, which was a substantial burden on patients and families in terms of both cost and time. Cost drivers were generally found to be dependent on SMA type. CONCLUSIONS Long-term robust studies are required to fully elucidate the economic burden of SMA. Considering that motor function can vary broadly, especially in Type 2 SMA, it would be beneficial to understand how costs and resource use are affected by different degrees of ambulation. Reporting data in terms of achieved motor function could also mitigate the challenges of comparing global data studies of small populations. Global, regional, and/or local data collection platforms and disease registry networks could play an important role in helping to address current data gaps.

Abstract
BACKGROUND SMA type 1 is a severe neurodegenerative disorder that, in the absence of curative treatment, leads to death before 1 year of age without ventilatory support. Three innovative therapies are available to increase life expectancy. PURPOSE (i) To increase knowledge about parents' experiences with their decision to have opted for an innovative therapy; (ii) to assess the middle-term psychological consequences in the parents' lives. METHODS We used an in-depth interview; a self-administrated questionnaire and self-report scales (BDI-II, STAI-Y, PSI-SF, SOC-13, PBA, DAS 16 and FICD). We compared parents hesitant before the decision to parents who were not-hesitant and the group of parents whose child was treated with gene therapy (GT) to parents whose child received another innovative therapy. MAIN RESULTS We included n = 18 parents of 13 children. Parent's mean age was 34.7 (±5.2), child's average age was 44.3 months (±38.0). Retrospectively, most parents felt involved by doctors in decision-making on treatment, they felt their point of view was considered and were satisfied with the effects of the treatment. The group of parents "non-hesitant" was more depressed (p < 0.001), more anxious (p = 0.022) and had higher parental stress (p = 0.026) than the group of "hesitant" parents; the group of "GT-treated" parents was more depressed (p = 0.036) than the group of parents with "other therapy". Qualitative data highlights revealed: the need to save the child's life at all costs; the fear of coping with end of life and palliative care, the high value of perceived physician confidence in the treatment, the hope that the child will acquire autonomy or be cured. At the time of the decision, no parents felt they fully understood all of the issues regarding therapy and the disease. CONCLUSION Hesitating before making a decision did not predispose parents to depression and anxiety. The narratives suggest that the parents faced a dilemma regarding their child's health in an urgent context. The decision was not final, and parents will continue to think about it throughout the care process.

Abstract
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that causes progressive autonomy loss and need for care. This does not only affect patients themselves, but also the patients’ informal caregivers (CGs) in their health, personal and professional lives. The big efforts of this multi-center study were not only to evaluate the caregivers’ burden and to identify its predictors, but it also should provide a specific understanding of the needs of ALS patients’ CGs and fill the gap of knowledge on their personal and work lives. Using standardized questionnaires, primary data from patients and their main informal CGs (n = 249) were collected. Patients’ functional status and disease severity were evaluated using the Barthel Index, the revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) and the King’s Stages for ALS. The caregivers’ burden was recorded by the Zarit Burden Interview (ZBI). Comorbid anxiety and depression of caregivers were assessed by the Hospital Anxiety and Depression Scale. Additionally, the EuroQol Five Dimension Five Level Scale evaluated their health-related quality of life. The caregivers’ burden was high (mean ZBI = 26/88, 0 = no burden, ≥24 = highly burdened) and correlated with patients’ functional status (rp = −0.555, p < 0.001, n = 242). It was influenced by the CGs’ own mental health issues due to caregiving (+11.36, 95% CI [6.84; 15.87], p < 0.001), patients’ wheelchair dependency (+9.30, 95% CI [5.94; 12.66], p < 0.001) and was interrelated with the CGs’ depression (rp = 0.627, p < 0.001, n = 234), anxiety (rp = 0.550, p < 0.001, n = 234), and poorer physical condition (rp = −0.362, p < 0.001, n = 237). Moreover, female CGs showed symptoms of anxiety more often, which also correlated with the patients’ impairment in daily routine (rs = −0.280, p < 0.001, n = 169). As increasing disease severity, along with decreasing autonomy, was the main predictor of caregiver burden and showed to create relevant (negative) implications on CGs’ lives, patient care and supportive therapies should address this issue. Moreover, in order to preserve the mental and physical health of the CGs, new concepts of care have to focus on both, on not only patients but also their CGs and gender-associated specific issues. As caregiving in ALS also significantly influences the socioeconomic status by restrictions in CGs’ work lives and income, and the main reported needs being lack of psychological support and a high bureaucracy, the situation of CGs needs more attention. Apart from their own multi-disciplinary medical and psychological care, more support in care and patient management issues is required.
