Child and family experiences with inborn errors of metabolism: a qualitative interview study with representatives of patient groups

The impact of a child's inborn error of metabolism: the parents' perspectives on restrictions, discrimination, family planning, and emergency management

BACKGROUND

To investigate the impact of children's inborn error of metabolism (IEMs) on the children's and their parents' lives from the parents' perspective. We focused on disease-related restrictions in various issues of daily life, experienced discrimination, parental family planning, and management of metabolic emergencies.

METHODS

We conducted a questionnaire-based survey with 108 parents of 119 children with IEM who attended a metabolic outpatient clinic. The children were categorized into 4 cohorts, based on increasing disease severity (cohort 1: IEMs with lowest severity, cohort 4: IEMs with highest severity), and compared by using Tobit regressions.

RESULTS

The severity of the child's IEM was associated with an increase in the intensity of perceived restrictions from the parents' perspective for themselves and their children in all aspects of life: in general, in contact with friends, in the pursuit of hobbies, in childcare/school/occupation, and due to emotional stress. The highest intensity of restrictions in all cohorts was found for the parents themselves in contact with friends (compared to cohort 1: cohort 2: c. 3.556, p = 0.002; cohort 3: c. 4.159, p = 0.003; cohort 4: c. 7.224, p < 0.001). Parents of 8% of children reported that their children were discriminated against because of IEM, with the highest proportion of affected children (43%) in cohort 4. Parental family planning decisions were influenced in 34% of parents, with fear of recurrence being a predominant aspect. Of the parents of children diagnosed with IEMs associated with metabolic emergencies, 68% stated that they felt well or very well prepared for the occurrence of a metabolic emergency, and 100% of parents were able to name the necessary action steps from memory. Nevertheless, 58% stated that they experienced an occurring emergency as rather or very stressful.

CONCLUSIONS

From the parents' perspective, the intensity of restrictions increased with the severity of the child's IEM. The study shows the high impact of IEM on parents of children with IEM and the daily challenges they face. These findings emphasize the importance of comprehensive support for parents of children with IEM.

Advance Care Planning for Children With Rare Diseases: A Pilot RCT

BACKGROUND AND OBJECTIVE

Pediatric rare diseases are often life-limiting conditions and/or require constant caregiving. Investigators assessed the initial efficacy of the FAmily CEntered (FACE) pediatric advance care planning (pACP), FACE-Rare, intervention on families' quality of life.

METHODS

A pilot-phase, single-blinded, intent-to-treat, randomized controlled clinical trial enrolled families from 1 pediatric quaternary hospital between 2021 and 2023. Intervention families received 3 weekly 60-minute (FACE-Rare pACP) sessions: (1) Carer Support Needs Assessment Tool or Action Plan, (2) Carer Support Needs Assessment Tol Action Plan Review, and (3) Pediatric Next Steps: Respecting Choices pACP. Controls received treatment as usual (TAU). Outcome measures were Beck Anxiety Inventory, Family Appraisal of Caregiving, Functional Assessment of Chronic Illness Therapy (FACIT)-Spirituality, and health care utilization. Generalized mixed effect models with γ response assessed the intervention effect at 3-month follow-up.

RESULTS

Children (n = 21) were aged 1 to 10 years, 48% male, 24% Black; and 100% technology dependent. Primary family caregivers (n = 21) were aged 30 to 43 years, 19% male, 19% Black; and 27% household income below the Federal poverty level. Dyads underwent 1:1 randomization: 9 to FACE-Rare and 12 to TAU. TAU caregivers reported statistically lower meaning and peace than FACE-Rare caregivers (0.9, P = .03, confidence interval [CI]: 0.75-0.99). Black caregivers reported significantly less caregiver distress (0.7, P = .04, CI: 0.47-0.98) than non-Black caregivers. Poor families reported more anxiety (3.5, P = .002, CI: 1.62-7.94), more caregiver strain (1.2, P = .006, CI: 1.07-1.42); and less family well-being (0.8, P = .02, CI: 0.64-0.95).

CONCLUSIONS

FACE®-Rare was feasible, acceptable, safe, and demonstrated initial efficacy, providing greater feelings of meaning and peace to caregivers. Poverty impacted well-being. A multisite trial is needed to determine generalizability.

Mothers' lived experience of caring for children with inborn errors of amino acid metabolism

BACKGROUND

Inborn errors of amino acid metabolism are chronic conditions that have many sequels. Mothers of these children are facing different challenges which are underdetermined. This study was done to explore lived experience of mothers caring for these children.

METHODS

This is an interpretive phenomenology with van Manen's approach which has 6 steps. Data were gathered by convenience and purposeful sampling. Nine mothers with different experiences were interviewed and the interviews were audiotaped.

RESULTS

Six final themes were revealed from the exploring mothers' experiences including the future tied to the past, psychosis in the shadow of a lost ideal child, rebellion and blaming, the ways of escaping difficulties, self-forgetting in the shadow of full-time care, passing difficulties in the duality of hope-hopelessness, caring in a continuum of isolation-socialization.

CONCLUSION

Mothers have multiple challenges in taking care of their children, especially psychologically and financially. So, nurses must plan programs for helping mothers of children with inborn errors of amino acid metabolism to reduce the effects of disease on mothers and consequently the children and the whole family.

Individual and Family Determinants for Quality of Life in Parents of Children with Inborn Errors of Metabolism Requiring a Restricted Diet: A Multilevel Analysis Approach

OBJECTIVE

The objective of this study was to compare the quality of life (QoL) for parents of children with inborn errors of metabolism (IEMs) requiring a restricted diet with French population norms and investigate parental QoL determinants.

STUDY DESIGN

This cross-sectional study included mothers and/or fathers of children < 18 years of age affected by IEMs requiring a restricted diet (except phenylketonuria) from January 2015 to December 2017. Parents' QoL was assessed using the World Health Organization Quality of Life BREF questionnaire and compared with age- and sex-matched reference values from the French general population. Linear mixed models were used to examine the effects of demographic, socioeconomic, disease-related, and psychocognitive factors on parental QoL, according to a 2-level regression model considering individuals (parents) nested within families.

RESULTS

Of the 1156 parents invited to participate, 785 (68%) were included. Compared with the general population, parents of children with IEMs requiring a restricted diet reported a lower QoL in physical and social relationship domains but a higher QoL in the psychological domain. In the multivariate analysis, characteristics associated with poorer parental QoL included both parent-related factors (being a father, older age, more educated parent, nonworking parent, greater anxiety, seeking more social support, and using less positive thinking and problem-solving coping strategies) and family-related factors (disease complications, increased number of hospital medical providers, child's younger age, single-parent family, and lower family material wealth).

CONCLUSION

Parents of children with IEMs requiring a restricted diet reported poorer QoL in physical and social relationship domains than population norms. Psychocognitive factors, beyond disease-specific and family-related characteristics, were the most important determinants influencing parental QoL and may represent essential aspects for interventions.

Parent-Reported Caregiving Roles of Siblings of Children with Inborn Errors of Metabolism

OBJECTIVES

Research examining sibling caregiving contributions to medically complex pediatric patients, including those with inborn errors of metabolism (IEMs), is limited. We assess caregiving roles and attributes of siblings and hypothesize that there will be differences in parent-reported contributions among siblings of children with IEMs and siblings of typically developing (TD) children.

STUDY DESIGN

A convergent parallel mixed-methods study design guided analysis of data from parental surveys and semistructured interviews. Interviews were conducted with parents (n = 49) of children with IEMs and parents (n = 28) of exclusively TD children. We used inductive thematic analysis to identify themes related to sibling caregiving. The caregiving and support roles for siblings (n = 55) of children with IEMs and siblings (n = 42) of TD children were coded to assess each sibling's caregiving contributions and personal attributes.

RESULTS

Logistic regressions, using generalized estimating equations, were fitted. Results showed that siblings of children with IEMs were significantly more likely to provide monitoring (odds ratio [OR]: 3.62, confidence interval [CI]: 1.30-10.07) and emotional/social support (OR: 4.02, CI: 1.67-9.67) than siblings of TD children. Themes arising from interviews with parents of children with IEMs focused on sibling attributes, parental expectations regarding sibling caregiving, and challenges to the sibling-sibling and parent-sibling relationships. Themes revealed nuances in the sibling caregiving experience.

CONCLUSION

Siblings of children with IEMs make meaningful caregiving contributions and may provide care differently than siblings of TD children. Understanding childhood caregiving roles may inform how health care providers and parents encourage sibling caregiving contributions into adulthood.

Role of Psychologists in Pediatric Metabolic Disorders

Metabolic disorders or inborn errors of metabolism (IEMs) can have a wide range of neurodevelopmental and behavioral presentations. These can vary with age and/or management or stressors from common childhood/intercurrent illnesses/procedures/interventions. Collaborative care models such as multidisciplinary metabolic clinics or colocated models with behavioral health clinics and metabolic clinics in the same location can be valuable resources in improving long-term outcomes in patients with IEM. Psychologists' expertise using behavioral interventions, screening, or adaptive/cognitive measures can help with diagnosis, treatment adherence, school performance, family support, community resources, transition to adolescence and young adulthood using health belief concepts to improve outcomes.

Caregiver burden, and parents' perception of disease severity determine health-related quality of life in paediatric patients with intoxication-type inborn errors of metabolism

Background

Living with a non-acute (phenylketonuria) or acute (e.g. urea cycle disorders, organic acidurias) intoxication-type inborn error of metabolism (IT-IEM) can have a substantial impact on health-related quality of life (HrQoL) of paediatric patients and their families. Parents take primary responsibility for treatment monitoring and experience worry and fear about their child's health status. Quantitative evidence on parental psychological factors which may influence the HrQoL of patients with IT-IEM are sparse to non-existent.

Methods

In this multicenter survey study 50 parents of IT-IEM patients (ages 5–19) assessed the severity of their child's disease, reported on caregiver burden, and proxy-rated their child's HrQoL. Additionally, 35 patient self-reports on HrQoL were obtained (n = 16 female patients, n = 19 male patients). Multiple linear regressions were conducted to examine the predictive power of child age, sex, medical diagnosis type (acute / non-acute), parental perceived disease severity and caregiver burden on patients' HrQoL. Mediation analyses were used to investigate the relation of caregiver burden and parental ratings of disease severity with patients' HrQoL.

Results

Significant regression models for self-reported [F(5,34) = 10.752, p < .001, R² adj.^. = 0.59] and parent proxy reported HrQoL [F(5,49) = 20.513, p < .001, R² adj.^. = 0.67] emerged. High caregiver burden and perceived disease severity predicted significantly lower patient self- and proxy-reported HrQoL while type of diagnosis (acute versus non-acute) did not. Female sex predicted significantly lower self-reported HrQoL. High caregiver burden was the mediating factor between high perceived severity of the child's disease and lower proxy- by parent rated HrQoL.

Conclusion

Detecting elevated burden of care and providing support for parents seems crucial to prevent adverse consequences for their children's HrQoL. Intervention studies are needed, to assess which support programs are most efficient.

•

Caregiver burden enforced by high parent-perceived disease severity is a considerable risk factor for low HrQoL in paediatric patients with IT-IEM.

•

The parent perspective was a better estimator for the impact of disease than the mere medical type of diagnosis.

•

Female sex predicted lower self-reported HrQoL

Establishing risk factors and outcomes for congenital hypothyroidism with gland in situ using population-based data linkage methods: study protocol

INTRODUCTION

There has been an increase in the birth prevalence of congenital hypothyroidism (CH) since the introduction of newborn screening, both globally and in the UK. This increase can be accounted for by an increase in CH with gland in situ (CH-GIS). It is not known why CH-GIS is becoming more common, nor how it affects the health, development and learning of children over the long term. Our study will use linked administrative health, education and clinical data to determine risk factors for CH-GIS and describe long-term health and education outcomes for affected children.

METHODS AND ANALYSIS

We will construct a birth cohort study based on linked, administrative data to determine what factors have contributed to the increase in the birth prevalence of CH-GIS in the UK. We will also set up a follow-up study of cases and controls to determine the health and education outcomes of children with and without CH-GIS. We will use logistic/multinomial regression models to establish risk factors for CH-GIS. Changes in the prevalence of risk factors over time will help to explain the increase in birth prevalence of CH-GIS. Multivariable generalised linear models or Cox proportional hazards regression models will be used to assess the association between type of CH and school performance or health outcomes.

ETHICS AND DISSEMINATION

This study has been approved by the London Queen Square Research Ethics Committee and the Health Research Authority's Confidentiality Advisory Group CAG. Approvals are also being sought from each data provider. Obtaining approvals from CAG, data providers and information governance bodies have caused considerable delays to the project. Our methods and findings will be published in peer-reviewed journals and presented at academic conferences.

Multidisciplinary Care of Patients with Inherited Metabolic Diseases and Epilepsy: Current Perspectives

More than 650 inherited metabolic diseases may present with epilepsy or seizures. These diseases are often multisystem, life-long and induce complex needs of patients and families. Multidisciplinary care involves all stages of disease management: diagnostics, specific or symptomatic, acute and chronic treatments, and integrated care that takes into account not only medical, but also manifold psychosocial, educational, vocational and other needs of patients and their caregivers. Care coordination is indispensable to ensure smooth transitions of care across life and disease stages, including management of emergencies, transition from pediatric to adult services and palliative care. Care pathways are highly diverse and have to find the right balance between highly specialized and locally provided services. While multidisciplinary teams consist of many professionals, a named supervising physician in a highly specialized healthcare setting and a care coordinator are highly important. As the greatest burden of care always falls onto the shoulders of patients and/or families, patient empowerment should be a part of every care pathway and include provision of required information, involvement into common decision-making, patient’s and family’s education, support for self-management, liaison with peer support groups and emotional/ psychological support. Due to the rarity and complexity of these diseases, sufficient expertise may not be available in a national healthcare system and cross-border services (virtual or physical) in the recently developed European Reference Networks should be ensured through the proper organization of referral systems in each EU and EEA country. Finally, digital technologies are particularly important in the provision of services for patients with rare diseases and can significantly increase the availability of highly specialized services and expertise.

Family Experiences with Care for Children with Inherited Metabolic Diseases in Canada: A Cross-Sectional Survey

BACKGROUND AND OBJECTIVE

Children with inherited metabolic diseases often require complex and highly specialized care. Patient and family-centered care can improve health outcomes that are important to families. This study aimed to examine experiences of family caregivers (parents/guardians) of children diagnosed with inherited metabolic diseases with healthcare to inform strategies to improve those experiences.

METHODS

A cross-sectional mailed survey was conducted of family caregivers recruited from an ongoing cohort study. Participants rated their healthcare experiences during their child's visits to five types of healthcare settings common for inherited metabolic diseases: the metabolic clinic, the emergency department, hospital inpatient units, the blood laboratory, and the pharmacy. Participants provided narrative descriptions of any memorable negative or positive experiences.

RESULTS

There were 248 respondents (response rate 49%). Caregivers were generally very or somewhat satisfied with the care provided at each care setting. Appropriate treatment, provider knowledge, provider communication, and care coordination were deemed essential aspects of satisfaction with care by the majority of participants across many settings. Memorable negative experiences were reported by 8-22% of participants, varying by setting. Among participants who reported memorable negative experiences, contributing factors included providers' demeanor, lack of communication, lack of involvement of the family, and disregard of an emergency protocol letter provided by the family.

CONCLUSIONS

While caregivers' satisfaction with care for children with inherited metabolic diseases was high, we identified gaps in family-centered care and factors contributing to negative experiences that are important to consider in the future development of strategies to improve pediatric care for inherited metabolic diseases.

Families' healthcare experiences for children with inherited metabolic diseases: protocol for a mixed methods cohort study

INTRODUCTION

Children with inherited metabolic diseases (IMDs) often have complex and intensive healthcare needs and their families face challenges in receiving high-quality, family centred health services. Improvement in care requires complex interventions involving multiple components and stakeholders, customised to specific care contexts. This study aims to comprehensively understand the healthcare experiences of children with IMDs and their families across Canada.

METHODS AND ANALYSIS

A two-stage explanatory sequential mixed methods design will be used. Stage 1: quantitative data on healthcare networks and encounter experiences will be collected from 100 parent/guardians through a care map, 2 baseline questionnaires and 17 weekly diaries over 5-7 months. Care networks will be analysed using social network analysis. Relationships between demographic or clinical variables and ratings of healthcare experiences across a range of family centred care dimensions will be analysed using generalised linear regression. Other quantitative data related to family experiences and healthcare experiences will be summarised descriptively. Ongoing analysis of quantitative data and purposive, maximum variation sampling will inform sample selection for stage 2: a subset of stage 1 participants will participate in one-on-one videoconference interviews to elaborate on the quantitative data regarding care networks and healthcare experiences. Interview data will be analysed thematically. Qualitative and quantitative data will be merged during analysis to arrive at an enhanced understanding of care experiences. Quantitative and qualitative data will be combined and presented narratively using a weaving approach (jointly on a theme-by-theme basis) and visually in a side-by-side joint display.

ETHICS AND DISSEMINATION

The study protocol and procedures were approved by the Children's Hospital of Eastern Ontario's Research Ethics Board, the University of Ottawa Research Ethics Board and the research ethics boards of each participating study centre. Findings will be published in peer-reviewed journals and presented at scientific conferences.

Inborn Errors of Metabolism Screening in Neonates: Current Perspective with Diagnosis and Therapy

Inborn errors of metabolism (IEMs) are rare hereditary or acquired disorders resulting from an enzymatic deformity in biochemical and metabolic pathways influencing proteins, fats, carbohydrate metabolism, or hampered some organelle function. Even though individual IEMs are uncommon, together, they represent a diverse class of genetic diseases, with new issues and disease mechanisms being portrayed consistently. IEM includes the extraordinary multifaceted nature of the fundamental pathophysiology, biochemical diagnosis, molecular level investigation, and complex therapeutic choices. However, due to the molecular, biochemical, and clinical heterogeneity of IEM, screening alone will not detect and diagnose all illnesses included in newborn screening programs. Early diagnosis prevents the emergence of severe clinical symptoms in the majority of IEM cases, lowering morbidity and death. The appearance of IEM disease can vary from neonates to adult people, with the more serious conditions showing up in juvenile stages along with significant morbidity as well as mortality. Advances in understanding the physiological, biochemical, and molecular etiologies of numerous IEMs by means of modalities, for instance, the latest molecular-genetic technologies, genome engineering knowledge, entire exome sequencing, and metabolomics, have prompted remarkable advancement in detection and treatment in modern times. In this review, we analyze the biochemical basis of IEMs, clinical manifestations, the present status of screening, ongoing advances, and efficiency of diagnosis in treatment for IEMs, along with prospects for further exploration as well as innovation.

The burden of pharmacological treatment on health-related quality of life in people with a urea cycle disorder: a qualitative study

BACKGROUND

Urea cycle disorders (UCD) are inborn errors of metabolism, typically presenting neonatally. Excess ammonia builds rapidly within the body risking hyperammonemic episodes and potentially death. Long-term management of the condition includes restrictive protein consumption, pharmacological interventions and, in extreme cases, liver transplantation. Pharmacological treatments such as sodium benzoate and sodium phenylbutyrate have proven effective but not without a multitude of negative attributes including poor taste, higher dosage and associated gastrointestinal discomfort that impacts health-related quality of life. Glycerol phenylbutyrate (GPB) has recently become a widely available pharmacological treatment with early reports of improved qualities, including taste and administration method. The following study aims to explore the burden of pharmacological treatment and the effects of the transition to GPB on health-related quality of life in people with a UCD.

RESULTS

Nine carers of children living with a UCD (mean age = 12.44, SD = 10.26) were interviewed regarding their experiences of pharmacological treatment in relation to their, and their child's, health-related quality of life after transitioning to GPB. Three main themes were identified: psychological health, physical health and social participation. Carers struggled with anxiety surrounding their child's condition and the battle of administering medication. Medication administration was perceived to have improved since the transition to GPB, alleviating distress for both carer and child. Issues involving school were described, ranging from difficulties integrating their child into mainstream schooling and the impact of treatment on participation in school and extracurricular activities. Carers encountered issues sourcing syringes to administer GPB, which induced stress. It could be suggested that some burden had been relieved by the transition to GPB. However, it appeared that difficulties associated with the illness would persist despite treatment, owing to the continuing nature of the condition.

CONCLUSIONS

Adhering to a strict pharmacological regime caused immense stress for both carers and children, severely impacting on typical social activities such as eating at a restaurant or going on holiday. GPB was perceived to have alleviated some burden in terms of administration given improved characteristics concerning taste and dosage, important characteristics for both carers and children living with UCD. Practitioners should consider these findings when making clinical decisions for children with UCD and the effect of pharmacological treatment on carer's health-related quality of life. Outreach work to facilitate greater understanding of the condition should be conducted with key locations, such as children's schools. This would also help to alleviate carer burden.

"It's Just Always Eating": The Experiences of Young People Growing up Medium Chain Acyl-coA Dehydrogenase Deficiency

Medium chain acyl-CoA dehydrogenase deficiency (MCADD) is a rare metabolic disorder, and commonly now part of newborn screening programs. Those diagnosed at birth are now progressing from childhood to adulthood. The study aim was to explore young people’s experiences of living with MCADD and managing their condition. A descriptive qualitative study design involving semi-structured interviews with 12 participants aged 10 to 15 years, recruited from one regional pediatric metabolic disorder service in England. Data were analyzed using thematic analysis. The two major themes were “Eating for energy” and “Growing into a self-management role.” Self-monitoring and self-management skills had been nurtured from early childhood by parents and healthcare providers. Young people’s anxieties concerned having to maintain adequate energy input to stay safe and the associated burden of responsibility. Growing up with MCADD presents specific challenges. Self-management and ongoing support are important for dealing with those challenges.

Parental psychosocial aspects and stressors involved in the management of inborn errors of metabolism

Parents of children with inborn errors of metabolism (IEM) face numerous psychosocial challenges. An increased understanding and awareness of these stressors can ensure better overall outcomes for the entire family. We conducted semi-structured, in-person interviews with ten parents to identify psychosocial stressors, strategies, and supports they utilized to overcome their challenges. Our interview guide was designed to elicit familial experiences during the pre- and post-diagnosis periods. The themes and sub-themes were identified through qualitative descriptive textual analysis of audio-recorded transcripts. Major themes identified include ambiguity of illness, changing family and spousal dynamics, and navigating the healthcare system. Sub-themes revolved around disease effects, psychological stressors, health systems, support, and facing the disease. Healthcare professionals have an opportunity to minimize the impact of negative emotional outcomes by assisting families as they navigate the experience of having a child with an IEM. Our findings can be used to develop and continue a more well-rounded, family-oriented framework for IEM management.

Choosing between medical management and liver transplant in urea cycle disorders: A conceptual framework for parental treatment decision-making in rare disease

Urea cycle disorders (UCD) are rare inherited metabolic disorders caused by deficiencies of enzymes and transporters required to convert neurotoxic ammonia into urea. These deficiencies cause elevated blood ammonia, which if untreated may result in death, but even with optimal medical management, often results in recurrent brain damage. There are two major treatments for UCD: medical management or liver transplantation. Both are associated with mortality and morbidity but the evidence comparing outcomes is sparse. Thus, families face a dilemma: should their child be managed medically, or should they undergo a liver transplant? To (a) describe the factors that contribute to treatment choice among parents of children diagnosed with UCD and to (b) organise these factors into a conceptual framework that reflects how these issues interrelate to shape the decision-making experience of this population. Utilising grounded theory, qualitative data were collected through semi-structured interviews with parents (N = 35) and providers (N = 26) of children diagnosed with UCD and parent focus groups (N = 19). Thematic content analysis and selective and axial coding were applied. The framework highlights the life-cycle catalysts that frame families' personal perceptions of risks and benefits and describes the clinical, personal, social, and system factors that drive treatment choice including disease severity, stability, and burden, independence, peer experiences, and cost, coverage and access to quality care. Findings equip providers with evidence upon which to prepare for productive patient interactions about treatment options. They also provide a foundation for the development of patient-centred outcome measures to better evaluate effectiveness of treatments in this population.

Perceived burden in dealing with different rare diseases: a qualitative focus group study

OBJECTIVES

There are more than 6000 heterogeneous rare diseases and little is known about shared experiences of affected individuals in everyday life and healthcare. Objective of this study was to explore perceived burden of patients with rare chronic diseases and identify commonalities and differences in the experiences of patients with four heterogeneous conditions.

DESIGN

A qualitative focus group study.

SETTING

In four separate and diagnostically homogeneous focus groups, we asked patients about the perceived burden of living with their rare disease. The focus groups took place at a university medical centre in Germany.

PARTICIPANTS

Individuals with neurofibromatosis type 1 (n=4), primary sclerosing cholangitis (n=5), pulmonary arterial hypertension (n=4) and Marfan syndrome (n=5).

RESULTS

We identified five main themes: medical problems, psychological burden, problems with the healthcare system, constraints and interpersonal problems. While medical problems differed widely between the diagnostic groups, patients with different conditions independently reported many common problems including psychological burden, constraints in professional, personal and daily life, stigmatisation and others lacking understanding. Shared problems pertaining to the healthcare system seem related to the rarity of the conditions (eg, limited access to adequate care, lack of knowledge).

CONCLUSIONS

Despite clinical heterogeneity of rare diseases, affected individuals have many common experiences. Some of these experiences may resemble the burden of living with a chronic disease. However, patients reported aspects, which seem to be specific for rare chronic diseases. Generic interventions targeting shared burdens among patients with different diseases could provide adequate treatment in light of finite healthcare resources.

Emotional experience in parents of children with Zellweger spectrum disorders: A qualitative study

Zellweger spectrum disorders (ZSDs) are rare, debilitating genetic diseases of peroxisome biogenesis that require constant management and lifelong care. Nevertheless, the experience of family caregivers for children diagnosed with ZSD is not well understood. In this study, we sought to characterize the emotional experience of ZSD family caregivers. Three 90-min focus groups were conducted with thirty-seven parents (25 mothers and 12 fathers) of children with ZSD during a family advocacy conference. Focus groups were arranged by age of proband (Group 1: 0-4 years, Group 2: 5-10 years, Group 3: >11 years). Audio recordings of focus groups were transcribed and analyzed using software for coding purposes. Analyzed content was validated using peer debriefing, member checking, and method triangulation. Focus group results showed that nearly a third of ZSD caregivers described their overall emotional experience as a "rollercoaster." Additionally, three interconnected themes were identified: 1) range of emotions, 2) stressors, and 3) coping. Feeling overwhelmed and devastated were the most frequently described emotional responses. Corresponding stressors to these emotions included the burden of caregiver tasks associated with ZSD, and negative interactions with healthcare professionals. The most common coping strategies were acceptance of limitations of the diseases, redefining "normal" in the parenting experience, and advocating on behalf of the child and the patient community. This study underscores the profound emotional impact on parents who are caregivers for children with ZSDs, highlighting the utility of patient community feedback and qualitative approaches to fully characterize the overall family experience. Simple, targeted approaches focusing on improved communication between healthcare professionals and families, as well as offering resources for emotional support may greatly improve the lives of families living with ZSD and other rare pediatric diseases.

The role of integrated behavioral health in caring for patients with metabolic disorders

This review of integrated behavioral health (IBH) provides a background on IBH models, and the benefits of IBH in pediatric practice with an emphasis on how IBH specialists can collaborate with families and clinicians. An overview of intellectual disability (ID) and psychiatric disorders focused on disorders of inborn errors of metabolism (IEM) highlights issues in assessment and monitoring of these patients with implications for clinical practice and the role of IBH in caring for patients with IEM disorders.

Parenting a Child with Phenylketonuria (PKU): an Interpretative Phenomenological Analysis (IPA) of the Experience of Parents

Phenylketonuria (PKU) is a rare inherited metabolic disorder which can cause neurological damage if left untreated. PKU is identified through newborn screening in developed countries, and treatment begins immediately to prevent these severe consequences. When a child is diagnosed, parents must assume immediate responsibility for the management of PKU and prevention of neurological damage. Quantitative studies have identified significant psychosocial stressors for parents, but little is known about how the parents experience this process. This study aimed to explore the experiences of parents of children with PKU under the age of two. It is the first study to examine these experiences in this way. Seven parents were interviewed about their experiences, and interpretative phenomenological analysis was used to analyse the data. Three main themes were identified: control, striving for normality and acceptance of PKU as a continuum. Links between the themes and processes underpinning the results were explored with relation to existing literature and theories from a clinical psychology perspective. The role of acceptance of PKU was central to the parent's experiences. Clinical implications and suggestions for further research are discussed.

Public and patient involvement in needs assessment and social innovation: a people-centred approach to care and research for congenital disorders of glycosylation

BACKGROUND

Public and patient involvement in the design of people-centred care and research is vital for communities whose needs are underserved, as are people with rare diseases. Innovations devised collectively by patients, caregivers, professionals and other members of the public can foster transformative change toward more responsive services and research. However, attempts to involve lay and professional stakeholders in devising community-framed strategies to address the unmet needs of rare diseases are lacking. In this study, we engaged with the community of Congenital Disorders of Glycosylation (CDG) to assess its needs and elicit social innovations to promote people-centred care and research.

METHODS

Drawing on a qualitative study, we conducted three think tanks in France with a total of 48 participants, including patients/family members (n = 18), health care professionals (n = 7), researchers (n = 7) and people combining several of these roles (n = 16). Participants came from 20 countries across five continents. They were selected from the registry of the Second World Conference on CDG through heterogeneity and simple random sampling. Inductive and deductive approaches were employed to conduct interpretational analysis using open, axial and selective coding, and the constant-comparison method to facilitate the emergence of categories and core themes.

RESULTS

The CDG community has unmet needs for information, quality health care, psychosocial support and representation in decision-making concerned with care and research. According to participants, these needs can be addressed through a range of social innovations, including peer-support communities, web-based information resources and a CDG expertise platform.

CONCLUSION

This is one of the few studies to engage lay and professional experts in needs assessment and innovation for CDG at a global level. Implementing the innovations proposed by the CDG community is likely to have ethical, legal and social implications associated with the potential donation of patients' clinical and biological material that need to be assessed and regulated with involvement from all stakeholders. To promote people-centred care for the CDG community, and increase its participation in the governance of care and research, it is necessary to create participatory spaces in which the views of people affected by CDG can be fully expressed.

Diagnosis of rare diseases under focus: impacts for Canadian patients

This paper presents an in-depth qualitative analysis of the impact of diagnosis on the lives of rare disease (RD) patients. While diagnosis may be described as a watershed step for RD patients, no extensive account of non-medical outcomes following a RD diagnosis exists within the literature. This study aims to fill this knowledge gap through an analysis of the impact of diagnosis on the lives of RD patients according to their personal experiences. Qualitative research was conducted in three provinces across Canada, with a total of 23 participants, both adult and parents of children with RD, diagnosed and not yet diagnosed. A thematic approach guided the analysis of the transcripts. The results reveal that the impacts of a RD diagnosis for both adults and paediatric patients are multifold, ranging from social to personal and medical impacts (including cases where etiological treatments for the diseases are non-existent). Furthermore, the results shed light on distinct factors that affect the scope of impacts of a diagnosis.

Development and Psychometric Evaluation of the MetabQoL 1.0: A Quality of Life Questionnaire for Paediatric Patients with Intoxication-Type Inborn Errors of Metabolism

INTRODUCTION

This study is part of the "European network and registry for intoxication type metabolic diseases" (E-IMD) project. Intoxication-type inborn errors of metabolism (IT-IEM) such as urea cycle disorders (UCD) and organic acidurias (OA) have a major impact on patients' lives. Patients have to adhere to strict diet and medication and may suffer from metabolic crises and neurocognitive impairment. Disease-specific health-related quality of life (HrQoL) assessment questionnaires are the method of choice to estimate the subjective burden of a disease. To date, no such instrument is available for IT-IEM.

METHODS

Disease-specific patient- and parent-reported HrQoL questions were constructed in German based on focus group interviews with patients and parents. Questionnaires for patients from 8 to 18 years were piloted with 14 participants (n = 9 children and adolescents, n = 5 parents) by cognitive debriefing and tested psychometrically with 80 participants (n = 38 patients, n = 42 parents) for item characteristics, validity, and reliability to construct the first version of a disease-specific HrQoL questionnaire.

RESULTS

Twenty-eight questions were selected based on item descriptives. Scales of self- and proxy questionnaires demonstrated acceptable to excellent reliability in terms of internal consistency (Cronbach's α = 0.70-0.93). Scales and total scores correlated with those of generic HrQoL questionnaires, showing convergent validity.

DISCUSSION

The MetabQoL 1.0 questionnaire exhibits sound psychometric properties and is a promising step towards assessing patient-reported outcomes in research and clinical practice. It provides a solid basis for translation into other languages and further elaboration and psychometric exploration in larger populations.

Experiences of caregivers of children with inherited metabolic diseases: a qualitative study

Background

We sought to understand the experiences of parents/caregivers of children with inherited metabolic diseases (IMD) in order to inform strategies for supporting patients and their families. We investigated their experiences regarding the management of disease, its impact on child and family life, and interactions with the health care system.

Methods

From four Canadian centres, we conducted semi-structured telephone interviews with parents/caregivers of children with an IMD who were born between 2006 and 2015 and who were participating in a larger cohort study. Participants were selected with the aim of achieving a diverse sample with respect to treatment centre, IMD, and age of the child. Interviews emphasized the impacts of the disease and its treatment on the child and family and explicitly queried perceptions of interactions with the health care system. We identified emergent themes from the interview data.

Results

We completed interviews with 21 parents/caregivers. The 21 children were aged <1 to 7 years old with IMD that included amino acid disorders, urea cycle disorders, fatty acid oxidation disorders, and organic acid disorders or ‘other’ IMD. Most parents reported that they and their families had adapted well to their child’s diagnosis. Parents used proactive coping strategies to integrate complex disease management protocols into routine family life. An important source of stress was concern about the social challenges faced by their children. Participants reported positive interactions with their most involved health care providers within the metabolic clinic. However, they reported challenges associated with the health care system outside of disease-specific metabolic care, when encountering systems and providers unfamiliar with the child’s disease.

Conclusions

The successful use of proactive coping strategies among parents of children with IMD in this study suggests the potential value of promoting positive coping and is an important direction for future study. Parents’ social concerns for their children were important stressors that warrant consideration by health care providers positioned to support families. Our results with respect to experiences with care highlight the important role of specialized metabolic clinics and point to a need for better coordination of the care that takes place outside the disease-specific management of IMD.

Living with Intoxication-Type Inborn Errors of Metabolism: A Qualitative Analysis of Interviews with Paediatric Patients and Their Parents

INTRODUCTION

Progress in diagnosis and treatment of patients with intoxication-type inborn errors of metabolism (IT-IEM) such as urea cycle disorders, organic acidurias or maple syrup urine disease is resulting in a growing number of long-term survivors. Consequently, health-related quality of life (HrQoL) of patients is increasingly regarded as a meaningful outcome parameter. To develop the first validated, disease-specific HrQoL questionnaire for IT-IEM, patients and parents were interviewed as content experts to identify major physical and psychosocial constraints and resources.

METHODS

Focus group interviews with 19 paediatric IT-IEM patients and 26 parents were conducted in four metabolic centres in Austria, Germany and Switzerland. Disease-specific HrQoL categories were established by qualitative content analysis.

RESULTS

Fourteen disease-specific topics related to the three well-established generic HrQoL dimensions of physical, mental and social functioning were derived from the interview transcripts. Both patients and parents perceived dietary restrictions and social stigmatisation as major burdens. Dietary restrictions and emotional burdens were more important for young (<8 years) patients, whereas cognition, fatigue and social issues were more relevant to older patients (≥8 years). Treatment-related topics had a significant effect on social and emotional HrQoL.

DISCUSSION

By exploring patients' and parents' perspectives, 14 HrQoL categories were identified. These new categories will allow the development of a disease-specific, standardised questionnaire to assess HrQoL in paediatric IT-IEM patients. Age-appropriate information on the disease and psychosocial support targeted to patients' individual burdens are essential to the delivery of personalised care that takes account of physical, mental and social dimensions of HrQoL.
