The psychosocial experience of individuals living with osteogenesis imperfecta: a mixed-methods systematic review

Resilience and coping: a qualitative analysis of cognitive and behavioral factors in adults with osteogenesis Imperfecta

PURPOSE

The aim of this qualitative study was to investigate resilience among adults with Osteogenesis Imperfecta (OI).

MATERIALS AND METHODS

Semi-structured interviews were conducted with 15 adults with OI. Transcripts were coded and subsequently abstracted, yielding themes specific to resilience and coping. Interview guides covered broad topics including pain challenges specific to OI, mental health issues related to OI, and priorities for future interventions for individuals with OI.

RESULTS

Participants described resilience in the context of OI as the ability to grow from adversity, adapt to challenges resulting from OI-related injuries, and find identities apart from their condition. Psychological coping strategies included acceptance, self-efficacy, cognitive reframing, perspective-taking, and positivity. Behavioral factors that helped participants develop resilience included developing new skills, pursuing meaningful goals, practicing spirituality, and seeking external resources such as psychotherapy, education, and connection with community.

CONCLUSION

Having identified how adults with OI define resilience and the strategies they use to cope, we can now develop interventions and guide healthcare providers in improving psychological wellbeing in this population.

Caregiver Burden, Parenting Stress and Coping Strategies: The Experience of Parents of Children and Adolescents with Osteogenesis Imperfecta

Only a few studies, mainly qualitative thematic analyses of interviews, have dealt with the psychological experience of parents of children and adolescents with osteogenesis imperfecta (OI), a rare genetic syndrome involving skeletal fragility and increased exposure to bone fractures. The aim of the present study was to evaluate both negative (i.e., parental burden and parenting stress) and positive (i.e., coping strategies and perceived social support) experiences of parents related to their children's disease and behaviour. The participants were 34 parents of children and adolescents with OI who completed a specifically developed online survey assessing their psychological experience with caregiving, their perception of the severity level of their children's condition and any possible behavioural problems experienced by their children. Data analyses showed that 65% of the parents showed a clinical level of caregiver burden and nearly 30% a clinical level of parenting stress. Caregiver burden was related to the perceived severity level of the condition and the externalising problems shown by their children. Concerning the positive aspects of the parents' experience, a high level of perceived social support was connected to a lower level of parenting stress; the same did not happen for caregiver burden. Coping strategies were connected to stress and burden; in particular, a higher level of stress corresponded to a higher level of avoidance, and a higher level of burden corresponded to a higher level of positive attitude.

Home care needs assessment among caregivers of children and adolescents with osteogenesis imperfecta: a cross-sectional study

BACKGROUND

Children and adolescents with complex medical issues need home care services; however, few studies have provided insight into the unmet home care needs of the families of patients with osteogenesis imperfecta (OI). In this study, we aimed to assess the home care needs of caregivers of children and adolescents with OI and the associated factors.

METHODS

A self-administered questionnaire was administered online to 142 caregivers of patients with OI aged 3-17 years between May and October 2022 from 25 provinces in China. The questionnaire comprised 15 questions on demographic variables and 14 questions on home care needs. Chi-square analysis was used to compare group differences for categorical variables. Multivariate binary logistic regression analysis was conducted to examine predictors of caregivers' home care needs.

RESULTS

The study findings indicated that 81.5% of caregivers had high home care needs. The three leading types of home care needs were helping the child carry out physical fitness recovery exercises at home (72.5%), understanding precautions regarding treatment drugs (72.5%), and relieving the child's pain (70.4%). OI patients' poor self-care ability (adjusted odds ratio = 5.9, 95% confidence interval = 1.8-19.0) was related to caregivers' high level of home care needs.

CONCLUSIONS

The findings of this study suggest that future scientific research and nursing guidance should focus on OI patients' physical training, medication management, pain relief, fracture prevention, and treatment. In addition, caregivers of patients with poor self-care ability should receive special attention in the development of interventions. This study can help with addressing the unmet home care needs of caregivers of children and adolescents with OI. It is vital to develop a personalized intervention plan based on patients' self-care ability.

The experiences of the families with children diagnosed with osteogenesis imperfecta: A Qualiative study in Turkey

BACKGROUND

The diagnosis of osteogenesis imperfecta affects the whole lives of family members. This study aims to investigate the lived experience of families with children diagnosed with osteogenesis imperfecta.

DESIGN AND METHODS

This study used a qualitative, phenomenological design. The study sample consisted of parents of the children who were followed up with the diagnosis of osteogenesis imperfecta in the pediatric endocrinology clinic in Turkey. In order to collect data, a semi-structured interview form was prepared, and data were collected by way of face-to-face interviews. The lived experience of families were analyzed using qualitative methods. The life experiences of the families were analyzed in depth using qualitative methods.

RESULTS

In the study, six themes were identified, including having a child diagnosed with osteogenesis imperfecta, family process, life patterns, emotional dimension, social life, and economic dimension. The results revealed that parents did not know about the disease upon learning of the child's diagnosis. Parents stated that they experienced anxiety, disappointment, sadness, denial, and despair when they first learned about their children's diagnosis. They also indicated that having a child with osteogenesis imperfecta affected the whole family in physiological, psychological, and social aspects.

CONCLUSION

Parents and children should be given information about the disease since the first diagnosis of osteogenesis imperfecta, and psychosocial support should be provided. Families that can not get sufficient psychosocial support experience difficulties in the medical and care management of the disease.

PRACTICE IMPLICATIONS

Knowing and understanding the lived experiences of families living with osteogenesis imperfecta can guide the planning and implementation of quality nursing care processes.

A qualitative exploration of patient perspectives on psychosocial burdens and positive factors in adults with osteogenesis imperfecta

Osteogenesis imperfecta (OI) is a pleiotropic, heritable connective tissue disorder associated with a wide range of health implications, including frequent bone fracture. While progress has been made to understand the spectrum of these physical health implications, the impact of OI on psychosocial well-being, as well as protective factors that buffer against adverse psychosocial outcomes, remain understudied. This present study relies on a qualitative approach to assess patient perspectives on both protective and adverse psychosocial factors specific to OI in 15 adults with varying disease status. Semi-structured interviews were conducted, subsequently coded, and themes extracted. Themes concerning psychosocial burdens (i.e., negative affective and behavioral impacts of disease status) and protective factors were identified from cooperatively-coded transcripts (two coders per transcript). Participants reported experiencing an increase in negative affect and disease-related distress after fracturing a bone and during recovery. Fear and concern specific to the uncertainty of future bone fractures and negative self-image was common. In contrast to these negative impacts, participants additionally described positive orientations toward their disease and attributed positive traits to their lived experience with a chronic disease. While limited due to small sample size and lack of ethno-racial diversity, findings highlight a need for continued research on the relationship between OI disease status and psychosocial outcomes, as well as the development of psychological interventions designed for OI populations. Findings have relevant clinical applications for healthcare providers working with those diagnosed with OI.

Impact of caregiver's eHealth literacy, financial well-being, and mental health on quality of life of pediatric patients with osteogenesis imperfecta

OBJECTIVE

This study assesses the association between health-related quality of life (HRQoL) for pediatric patients with osteogenesis imperfecta (OI) and their caregivers' eHealth literacy (eHL), financial well-being, and mental health along with the impact of eHealth literacy on the financial well-being and mental health of OI caregivers.

METHODS

Participants were recruited from a member pool of two OI patient organizations in China. Information about patients' HRQoL and their caregivers' eHL, financial well-being, and mental health was collected. Structure equation modeling (SEM) was used to estimate the relationship between the measures. The robust weighted least square mean and variance adjusted estimator was used. Three criteria, the comparative fit index, the Tucker-Lewis index, and the root mean square error of approximation, were used to evaluate the goodness-of-fit of the model.

RESULTS

A total of 166 caregivers completed the questionnaires. Around 28.3% indicated that pediatric OI patients experienced problems related to mobility, and 25.3% reported difficulty doing usual activities. Around 52.4% of caregivers reported that their care receivers have some emotional problems while 8.4% reported that their care receivers have "a lot of" emotional problems. 'Some problems' on all dimensions on EQ-5D-Y was the most frequently reported health state (13.9%), and around 10.0% have no problems on all dimensions on EQ-5D-Y. Caregivers tended to show a significantly high eHL, financial well-being, and mental health when their care receivers reported no problems with usual activities and emotions. The SEM demonstrated a significant and positive relationship between eHL, financial well-being, and mental health.

CONCLUSION

OI caregivers with high eHL reported satisfactory financial well-being and mental health; their care receivers rarely reported living with poor HRQoL. Providing multicomponent and easy-to-learn training to improve caregivers' eHL should be highly encouraged.

The Design, Development, and Usability Testing of an eHealth Program for Youths With Osteogenesis Imperfecta: Protocol for a 2-Phase User-Centered Mixed Methods Study

BACKGROUND

Innovative approaches are needed to address the self-management needs of youths with osteogenesis imperfecta (OI) transitioning into adult-oriented health care systems. Using a sequentially phased research approach, the goal is to design, develop, and test the usability of an innovative eHealth program called "Teens Taking Charge: Managing OI Online," hereafter named "Teens OI." This program seeks to optimize self-management, facilitate a successful transition to adult care, and address a critical gap in the quality of care for youths with OI.

OBJECTIVE

The study objectives are to (1) design and develop an English and French version of the Teens OI and (2) test the usability of the Teens OI in terms of efficiency, effectiveness, and satisfaction from the perspectives of youths with OI and their parents.

METHODS

A user-centered design is presently in progress to design and develop Teens OI. A "Website Design and Development Council" (ie, Council) has been convened, with 20 youths and parent dyads recruited and global experts surveyed at an international meeting. With unanimous support from the Council, usability testing of the Teens OI will ensue in 4 iterative cycles with 32 youth-parent dyads. All sociodemographic and usability metrics will be descriptively analyzed. All recorded interview and focus group data are analyzed using content analysis techniques involving an iterative process of data reduction, data display, conclusion drawing, and verification.

RESULTS

As of December 2022, an 8-person, interdisciplinary Teens OI council, comprising 4 health care professionals, 3 youths and young adults with OI, and 1 parent, has been convened to oversee the design and development of Teens OI. Two cycles of interviews have been conducted with 10 youths with OI with or without their parents (n=6) from December 2021 to September 2022. Data analysis has been in progress since April 2022. Aim 2 is ethically approved and will commence following the completion of content development, expected by late July 2023. Preliminary analysis indicates that the following topics need to be prioritized for the youths: mental health, pain, accessibility, medical care, education, community, and parental care.

CONCLUSIONS

The proposed study will design and develop a self-management and transitional care program for youths with OI in partnership with patients, caregivers, and health care professionals. This study leverages youths' openness to adopt eHealth technologies to meet their needs and has the potential to actively engage them to autonomously manage their lifelong conditions, and facilitate a successful transition to adult health care. Finally, the proposed study will also address a critical gap in the quality of care and the growing concern that the OI population transitioning from pediatric to adult care is at risk of various adverse events associated with the transition.

Quality of life of pediatric and adult individuals with osteogenesis imperfecta: a meta-analysis

BACKGROUND

Osteogenesis imperfecta (OI) is a group of rare inheritable disorders of connective tissue. The cardinal manifestations of OI are low bone mass and reduced bone mineral strength, leading to increased bone fragility and deformity that may lead to significant impairment in daily life. The phenotypic manifestations show a broad range of severity, ranging from mild or moderate to severe and lethal. The here presented meta-analysis aimed to analyze existing findings on quality of life (QoL) in children and adults with OI.

METHODS

Nine databases were searched with predefined key words. The selection process was executed by two independent reviewers and was based on predetermined exclusion and inclusion criteria. The quality of each study was assessed using a risk of bias tool. Effect sizes were calculated as standardized mean differences. Between-study heterogeneity was calculated with the I² statistic.

RESULTS

Among the studies included two featured children and adolescents (N = 189), and four adults (N = 760). Children with OI had significantly lower QoL on the Pediatric quality of life inventory (PedsQL) with regards to the total score, emotional, school, and social functioning compared to controls and norms. The data was not sufficient to calculate differences regarding OI-subtypes. In the adult sample assessed with Short Form Health Survey Questionnaire, 12 (SF-12) and 36 items (SF-36), all OI types showed significantly lower QoL levels across all physical component subscales compared to norms. The same pattern was found for the mental component subscales namely vitality, social functioning, and emotional role functioning. The mental health subscale was significantly lower for OI type I, but not for type III and IV. All of the included studies exhibited a low risk of bias.

CONCLUSIONS

QoL was significantly lower in children and adults with OI compared to norms and controls. Studies in adults comparing OI subtypes showed that the clinical severity of the phenotype is not related to worse mental health QoL. Future research is needed to examine QoL in children and adolescents in more sophisticated ways and to better understand the association between clinical severity of an OI-phenotype/severity and mental health in adults.

The patient clinical journey and socioeconomic impact of osteogenesis imperfecta: a systematic scoping review

BACKGROUND

Osteogenesis imperfecta (OI) is a rare heritable connective tissue disorder primarily characterised by skeletal deformity and fragility, and an array of secondary features. The purpose of this review was to capture and quantify the published evidence relating specifically to the clinical, humanistic, and economic impact of OI on individuals, their families, and wider society.

METHODS

A systematic scoping review of 11 databases (MEDLINE, MEDLINE in-progress, EMBASE, CENTRAL, PsycINFO, NHS EED, CEA Registry, PEDE, ScHARRHUd, Orphanet and Google Scholar), supplemented by hand searches of grey literature, was conducted to identify OI literature published 1st January 1995-18th December 2021. Searches were restricted to English language but without geographical limitations. The quality of included records was assessed using the AGREE II checklist and an adapted version of the JBI cross-sectional study checklist.

RESULTS

Of the identified 7,850 records, 271 records of 245 unique studies met the inclusion criteria; overall, 168 included records examined clinical aspects of OI, 67 provided humanistic data, 6 reported on the economic impact of OI, and 30 provided data on mixed outcomes. Bone conditions, anthropometric measurements, oral conditions, diagnostic techniques, use of pharmacotherapy, and physical functioning of adults and children with OI were well described. However, few records included current care practice, diagnosis and monitoring, interactions with the healthcare system, or transition of care across life stages. Limited data on wider health concerns beyond bone health, how these concerns may impact health-related quality of life, in particular that of adult men and other family members, were identified. Few records described fatigue in children or adults. Markedly few records provided data on the socioeconomic impact of OI on patients and their caregivers, and associated costs to healthcare systems, and wider society. Most included records had qualitative limitations.

CONCLUSION

Despite the rarity of OI, the volume of recently published literature highlights the breadth of interest in the OI field from the research community. However, significant data gaps describing the experience of OI for individuals, their families, and wider society warrant further research to capture and quantify the full impact of OI.

Transition of young adults with metabolic bone diseases to adult care

As more accurate diagnostic tools and targeted therapies become increasingly available for pediatric metabolic bone diseases, affected children have a better prognosis and significantly longer lifespan. With this potential for fulfilling lives as adults comes the need for dedicated transition and intentional care of these patients as adults. Much work has gone into improving the transitions of medically fragile children into adulthood, encompassing endocrinologic conditions like type 1 diabetes mellitus and congenital adrenal hyperplasia. However, there are gaps in the literature regarding similar guidance concerning metabolic bone conditions. This article intends to provide a brief review of research and guidelines for transitions of care more generally, followed by a more detailed treatment of bone disorders specifically. Considerations for such transitions include final adult height, fertility, fetal risk, heritability, and access to appropriately identified specialists. A nutrient-dense diet, optimal mobility, and adequate vitamin D stores are protective factors for these conditions. Primary bone disorders include hypophosphatasia, X-linked hypophosphatemic rickets, and osteogenesis imperfecta. Metabolic bone disease can also develop secondarily as a sequela of such diverse exposures as hypogonadism, a history of eating disorder, and cancer treatment. This article synthesizes research by experts of these specific disorders to describe what is known in this field of transition medicine for metabolic bone diseases as well as unanswered questions. The long-term objective is to develop and implement strategies for successful transitions for all patients affected by these various conditions.

The moral experiences of children with osteogenesis imperfecta

BACKGROUND

Serious ethical problems have been anecdotally identified in the care of children with osteogenesis imperfecta (OI), which may negatively impact their moral experiences, defined as their sense of fulfillment towards personal values and beliefs.

RESEARCH AIMS

To explore children's actual and desired participation in discussions, decisions, and actions in an OI hospital setting and their community using art-making to facilitate their self-expression.

RESEARCH DESIGN

A focused ethnography was conducted using the moral experiences framework with data from key informant interviews; participant observations, semi-structured interviews, and practice-based research (art-making) with 10 children with OI; and local documents.

PARTICIPANTS AND RESEARCH CONTEXT

The study was conducted at a pediatric, orthopedic hospital.

ETHICAL CONSIDERATIONS

This study was approved by McGill University Institutional Review Board.

FINDINGS/RESULTS

Children expressed desires to participate in their care, but sometimes lacked the necessary resources and encouragement from healthcare providers. Art-making facilitated children's voice and participation in health-related discussions.

CONCLUSIONS

Healthcare providers are recommended to consider the benefits of art-making and educational resources to reduce discrepancies between children's actual and desired participation in care and promote positive moral experiences.

The prevalence of musculoskeletal pain and therapy needs in adults with Osteogenesis Imperfecta (OI) a cross-sectional analysis

BACKGROUND

Osteogenesis Imperfecta affects approximately 1 in every 10,000 people. Musculoskeletal disorders and pain are common in adults with Osteogenesis Imperfecta, but specific knowledge of the problems people have is lacking. Access to therapy services for adults with Osteogenesis Imperfecta is variable. We designed this analysis to better understand the musculoskeletal disorders and consequent therapy needs for adults with Osteogenesis Imperfecta.  METHODS: This study was a cross-sectional analysis of outpatients with Osteogenesis Imperfecta. Adults attending a newly established multidisciplinary clinic at a tertiary centre in 2019 were included. A highly specialist physiotherapist worked within the clinic to offer therapy input if required and to refer patients to appropriate therapy as needed. People over the age of 18 were included if they had a diagnosis of Osteogenesis Imperfecta. Data were collected over a five month period using routinely collected clinical information and patient reported outcomes.

RESULTS

Over five months 50 patients attended the clinic. Musculoskeletal pain was a significant feature reported by 84% of patients. Over 50% of patients reported persistent pain for longer than one year duration and the most common site of pain was in the spine (46%). No difference in pain between types of OI and age. Forty five per cent (n = 19) of patients reported moderate to severe problems with mobility on the EQ-5D with over half reporting problems with self-care and ability to carry out usual activities. Over 50% of patients in clinic also reported anxiety (EQ-5D). During the consultation 70% of patients received therapy input which was either advice in clinic or an onward referral to the appropriate service. The referral rate to specialist out-patient rehabilitation services at a tertiary centre was 30%.

CONCLUSIONS

This analysis highlights the high prevalence of MSK pain in adults with OI and the effect on physical function and emotional wellbeing. This study demonstrates the diverse needs of the adult Osteogenesis Imperfecta population and the need for suitable multidisciplinary therapy services.

Fractures in Osteogenesis Imperfecta: Pathogenesis, Treatment, Rehabilitation and Prevention

Fractures in patients with osteogenesis imperfecta (OI) are caused by a decreased strength of bone due to a decreased quality and quantity of bone matrix and architecture. Mutations in the collagen type 1 encoding genes cause the altered formation of collagen type I, one of the principal building blocks of bone tissue. Due to the complexity of the disease and the high variation of the clinical problems between patients, treatment for these patients should be individually tailored. In general, short immobilization periods with flexible casting material, use of intramedullary implants, and simultaneous deformity correction are preferred. Multidisciplinary care with a broad view of the support needed for the patient and his/her living environment is necessary for the optimal rehabilitation of these patients. Increasing bone strength with exercise, medication, and sometimes alignment surgery is generally indicated to prevent fractures.

Eat, breathe, sleep with Osteogenesis Imperfecta

BACKGROUND

Although Osteogenesis Imperfecta (OI) affects the connective tissue causing extremely brittle bones with consequent skeletal deformities, it is important to go beyond bones. Indeed, the quality of life in OI does not only depend on bones status, as OI might affect also other important functions. We have therefore implemented a multidisciplinary study to assess lung function, breathing pattern, sleep quality and nutritional status in 27 adult OI type III and IV patients (median age: 34.6 years; 19 women; 14 type III).

RESULTS

According to nocturnal oxygen desaturation, two groups were identified: 13 patients with (OI_OSA, incidence: 48.2%) and 14 without (no_OSA) obstructive sleep apnea. The former was characterized by higher spinal and ribcage deformity, by more restrictive lung function, by paradoxical thoracic breathing in supine position, by rapid and shallow breathing, by higher body mass index, by longer neck and waist circumferences; by higher abdominal volume and by greater percentage of body fat mass, particularly localized in the trunk. The best predictor of OI_OSA was the negative value of the supine ribcage contribution to tidal volume, followed by the ratio between the neck and the waist circumferences with body height and the supine thoraco-abdominal volumes phase shift angle.

CONCLUSIONS

The pathophysiology of OI ensued a dangerous vicious circle, in which breathing, sleep and nutritional status are tightly linked, and they might all end up in negatively affecting the quality of life. The vicious circle is fed by some intrinsic characteristics of the disease (thoracic, cranial and mandibular deformities) and some bad daily habits of the patients (i.e. physical inactivity and low dietary quality). The former impacts on restricting the respiratory function, the latter makes Olers more prone to experience overweight or obesity. The main consequence is a high incidence of obstructive sleep apnea, which remains an underdiagnosed disorder in individuals with severe OI who are obese, with a neck to height ratio over than 31.6%, and characterized by paradoxical breathing in supine position. A multidisciplinary approach, including evaluations of breathing, sleep and nutrition, is required to better manage the disease and fulfil the maximizing well-being of OI patients.

Knowledge, attitude and practices regarding health self-management among patients with osteogenesis imperfecta in China: an online cross-sectional survey

OBJECTIVES

Assessing the knowledge, attitude and practices (KAP) regarding health self-management among patients with osteogenesis imperfecta (OI) in China.

DESIGN

An online cross-sectional survey.

SETTING

A structured questionnaire was distributed online through China-Dolls Center for Rare Disorders (CCRD), a non-governmental charity in China.

PARTICIPANTS

Participants were all patients with OI from CCRD. After stratified sampling according to the economic level of residential city, 901 patients were proportionally selected and 869 patients completed the survey (response rate: 96.4%).

MAIN OUTCOME MEASURES

Demographic characteristics and KAP information were gathered using a 5-point Likert scale. The score of each dimension of KAP was the sum of the scores of all included items. Χ² test or Fisher's exact test was used to compare scores of different items. Ordinal regression was employed to determine the significant factors influencing KAP.

RESULTS

A total of 802 questionnaires were included for analysis. Male respondents accounted for 57.1%, and 29.1% of respondents were of 26~30 years. More than half (50~60%) of patients knew the main symptoms of OI and the treatment of OI-related complications. Almost 80% of patients showed positive attitude. Nearly 60~70% of the patients were relatively able to take appropriate practice regarding OI management. There was a significant correlation between scores of knowledge and attitude, attitude and practice, as well as knowledge and practice. Patients aged 26~30 years, from urban areas and big cities, had higher KAP scores. Male patients showed better performance in knowledge, and highly educated patients perform better in practice.

CONCLUSIONS

Patients with OI did not have sufficient knowledge on disease care and up-to-date caring guidelines, and their practice regarding health self-management also needs to be improved. Gender, age, educational level and economic level of residence can affect the level of KAP for patients, thus developing targeted and tailored programmes for patients with OI is highly recommended.

Experiences of Children With Osteogenesis Imperfecta in the Co-design of the Interactive Assessment and Communication Tool Sisom OI: Secondary Analysis of Qualitative Design Sessions

BACKGROUND

Children with osteogenesis imperfecta (OI) experience a diversity of symptoms that expose them to difficult physical, mental, and social challenges. Sisom (DHealth) is an interactive assessment and communication tool designed to help children aged 6-12 years with chronic conditions express their symptoms. Recently, the co-design of the Sisom OI paper prototype was launched by seeking the perspectives of end users, including children with OI and their clinicians.

OBJECTIVE

The aim of this study is to describe the experiences that children with OI were prompted to share with researchers during the co-design of the Sisom OI paper prototype.

METHODS

A secondary analysis of qualitative data was conducted at a university-affiliated, pediatric, orthopedic hospital. The data sources consisted of interview transcripts, drawings, field notes, and observations derived from interviewing 12 children with OI who participated in the co-design of the Sisom OI paper prototype. The themes and subthemes identified from the data sources were generated using qualitative description.

RESULTS

Three themes were identified. The first, Relating to Others, described the balance between feeling different versus feeling similar to other children. The subthemes were Common OI Experience, Feeling Different, and Feeling Just Like Others. The second, Relating to Their Condition, described children's positive and negative interactions with their own condition and health care. The subthemes were Understanding Their Condition, Special Relationship with the Hospital, and Difficult Treatments and Procedures. The third, Reflecting on Capabilities, described children's recognition of their strengths and limitations. The subthemes were Perceiving Limitations, Overcoming Isolation, and Celebrating Strengths.

CONCLUSIONS

This co-design process provided children with OI the space to not only contribute to the development of the end product but also eloquently describe their experiences. These findings, based on the descriptions given by the children themselves, offer us a unique understanding of what it means to grow up with OI.

Living with Osteogenesis Imperfecta: A qualitative study exploring experiences and psychosocial impact from the perspective of patients, parents and professionals

BACKGROUND

Osteogenesis Imperfecta (OI) is a rare genetic condition characterised by increased bone fragility. Recurrent fractures, pain and fatigue have a considerable impact on many aspects of the life of a person affected with OI and their families.

OBJECTIVE

To improve our understanding of the impact of OI on the daily lives of individuals and families and consider how the condition is managed so that support needs can be better addressed.

METHODS

Semi-structured qualitative interviews (n = 56) were conducted with adults affected with OI, with (n = 9) and without children (n = 8), parents of children affected with OI (n = 8), health professionals (n = 29) and patient advocates (n = 2). Interviews were digitally recorded, transcribed verbatim and analysed using thematic analysis.

RESULTS

Three overarching themes are described: OI is not just a physical condition, parenting and family functioning and managing the condition. Fractures, chronic pain and tiredness impact on daily life and emotional well-being. For parents with OI, pain, tiredness and mobility issues can limit interactions and activities with their children. Specialist paediatric health services for OI were highly valued. The need for more emotional support and improved coordination of adult health services was highlighted.

CONCLUSIONS

Our findings allow a better understanding of the day-to-day experiences of individuals and families affected with OI. Supporting emotional well-being needs greater attention from policy makers and researchers. Improvements to the coordination of health services for adults with OI are needed and an in-depth exploration of young people's support needs is warranted with research focused on support through the teenage years.

Left to themselves: Time to target chronic pain in childhood rare diseases

BACKGROUND

Chronic pain is prevalent among patients with rare diseases (RDs). However, little is understood about how biopsychosocial mechanisms may be integrated in the unique set of clinical features and therapeutic challenges inherent in their pain conditions.

METHODS

This review presents examples of major categories of RDs with particular pain conditions. In addition, we provide translational evidence on clinical and scientific rationale for psychosocially- and neurodevelopmentally-informed treatment of pain in RD patients.

RESULTS

Neurobiological and functional overlap between various RD syndromes and pain states suggests amalgamation and mutual modulation of the respective conditions. Emotional sequelae could be construed as an emotional homologue of physical pain mediated via overlapping brain circuitry. Given their clearly defined genetic and molecular etiologies, RDs may serve as heuristic models for unraveling pathophysiological processes inherent in chronic pain.

CONCLUSIONS

Systematic evaluation of chronic pain in patients with RD contributes to sophisticated insight into both pain and their psychosocial correlates, which could transform treatment.

A standard set of outcome measures for the comprehensive assessment of osteogenesis imperfecta

BACKGROUND

Osteogenesis Imperfecta (OI) is a genetic disorder also known as 'brittle bone disease'. The clinical manifestation of OI shows a wide variation. Therefore, care for patients with OI requires an interdisciplinary approach. The effectiveness of particular interventions and treatment protocols of interdisciplinary teams is not clear due to a non-standardized and wide variation of patient outcomes thus making the comparison of outcome measures available in the literature difficult. It is only by agreeing on a common, standard set of outcome measures for the comprehensive appraisal of OI that comparisons across interdisciplinary treatment centers for OI will be possible in the future.

METHODS

The Key4OI international interdisciplinary working group of 27 members used a consensus-driven modified Delphi approach to develop a set of global outcome measures for patients with OI. The International Classification of Functioning, Disability and Health (ICF), was used to define domains and organize the outcomes from the literature search. After reviewing the outcomes extracted from the literature, trials and registries, the working group agreed on a final selection of domains and their definition (ICF definition as well as a lay description). These domains were then presented to the focus groups who prioritized the outcome domains by taking into account the items important to the OI community. All content was collected and analyzed and final domains were determined. A consensus of appropriate measuring instruments for each domain was reached with Delphi rounds. The entire approach was in line with the International Consortium for Health Outcomes Measurement ICHOM methodology.

RESULTS

More than 400 different outcome measures were identified in our literature search. After three Delphi rounds, 24 domains were selected. After the focus group sessions, the number of domains were reduced to 15. A consensus was reached on the measuring instruments to cover these domains for both children and adults.

CONCLUSION

The Key4OI project resulted in standard set of outcome measures focused on the needs and wishes of individuals with OI and their families. This outcome set will enable healthcare teams and systems to compare and to improve their care pathways and quality of care worldwide. Further studies are needed to evaluate the implementation of this standardized outcome set.

Parents' Perceptions of Health-Related Quality of Life of Children Diagnosed with Osteogenesis Imperfecta

PURPOSE

The purpose of this research was to describe the health-related quality of life (HRQoL) perceptions of parents of children diagnosed with osteogenesis imperfecta (OI).

DESIGN AND METHODS

This research used a descriptive design with a comparative sample. The Child Health Questionnaire (CHQ-PF 28) parent form was used to assess HRQoL in a sample of 37 parents from a mid-western tertiary pediatric hospital OI specialty clinic. Comparisons were made with a sample of parents of well children.

RESULTS

Parent HRQoL perception scores were described in both the physical and psycho-social-emotional domains. The domains of physical function (PF), bodily pain (BP), general health (GH), parent impact-emotional (PE), and child self-esteem (SE) were the lowest HRQoL mean domain scores for the parents of the children diagnosed with OI. Ceiling and floor scores were calculated to describe the magnitude of the differences between the mean HRQoL perception domain scores of the two parent groups.

CONCLUSIONS

Low HRQoL physical and psycho-social-emotional mean domain scores in conjunction with small percentage scores in the ceiling (and greater percentage scores in the floor) for parents of children diagnosed with OI were described. Findings suggest the on-going need for research to identify interventions to promote physical functioning for the child diagnosed with OI. Outcome based programs for parent and family-centered psycho-social self-care should be developed. PracticeImplications: ip Comprehensive and longitudinal assessment of HRQoL for both parents and their children diagnosed with OI will assist in documenting the outcomes of interventions for the management of chronic care.

Giving Children With Osteogenesis Imperfecta a Voice: Participatory Approach for the Development of the Interactive Assessment and Communication Tool Sisom OI

BACKGROUND

Children with osteogenesis imperfecta (OI) experience acute and chronic symptoms that expose them to physical, mental, and social challenges. Empowering these children by involving them in their care can help them to cope with OI. Sisom is an interactive assessment and communication tool designed to help children aged 6-12 years with chronic illnesses express their symptoms. This tool has not yet been adapted to the unique needs of OI.

OBJECTIVE

The aim of this study was to develop a Sisom OI paper prototype by seeking the perspectives of end users.

METHODS

A participatory approach was adopted to develop the prototype overseen by an expert panel of 9 clinicians at a university-affiliated pediatric hospital. Purposive sampling was used to recruit 12 children with OI who were aged 6-12 years. The study was carried out over the course of 3 feedback cycles. Data were deductively interpreted using content analysis techniques.

RESULTS

Overall, 64% (57/89) of the Sisom symptoms were deemed relevant for inclusion in Sisom OI, with 42% (37/89) directly incorporated and 22% (20/89) incorporated with changes. In total, 114 symptoms were used to create the prototype, of which 57 were newly generated. The relevant symptoms addressed children's thoughts and feelings about hospitalization and their wishes for participation in their own care. The new symptoms addressed fractures, body image, and social isolation related to difficulties with accessibility and intimidation.

CONCLUSIONS

Once developed, Sisom OI will offer clinicians an innovative and child-centered approach to capture children's perspectives on their condition.

Bladder and bowel symptoms experienced by children with osteogenesis imperfecta

OBJECTIVE

To estimate the prevalence and presentation of bladder, bowel, and combined bladder and bowel symptoms experienced by children with osteogenesis imperfecta and to describe the socio-demographic and clinical profile of these children.

METHOD

A descriptive study was conducted with a convenience sample of parent-child pairs of toilet-trained children aged from 3 to 18 years. Pairs were interviewed using three tools: (1) Socio-Demographic and Clinical Questionnaire; (2) Dysfunctional Voiding Scoring System; (3) Rome III Criteria along with the Bristol Stool Scale. Data were stratified by socio-demographic and clinical variables and analyzed using descriptive statistics.

RESULTS

Thirty-one parent-child pairs participated in the study; 38.7% (n=12) children reported bowel symptoms, 19.4% (n=6) reported a combination of bladder issues (such as holding maneuvers and urgency) and bowel symptoms (such as hard or painful bowel movements and large diameter stools). There were no reports of isolated bladder issues. Among the child participants, 16 (51.7%) identified as female and 20 (64.5%) were 5-14 years old. The most prevalent type of osteogenesis imperfecta was type III (n=12; 38.7%) and eight (25.8%) children reported using a wheelchair.

CONCLUSION

This is the first study to examine the prevalence and presentation of bladder, bowel, and combined bladder and bowel symptoms in children with osteogenesis imperfecta, offering a preliminary socio-demographic and clinical profile of these children. This research is an important step toward effective screening, detection, and access to care and treatment, especially for clinicians working with this group of very fragile patients.

Exploring the Perceived Self-management Needs of Young Adults With Osteogenesis Imperfecta

PURPOSE

To explore the perceived self-management needs of young adults with osteogenesis imperfecta (OI) with the goal of optimizing the self-management and transitional care services.

METHODS

A qualitative descriptive study was performed with young adults diagnosed with OI. Two semistructured interviews were conducted before and after their first appointment with a nurse practitioner in the adult healthcare settings (a new partnership initiated by the pediatric hospital). Data were transcribed and descriptively analyzed.

RESULTS

Seven participants with OI types I, III, and IV were interviewed. Ages ranged from 23 to 34 years, and years since discharge from the pediatric hospital ranged from 3 to 10. Four themes emerged including (1) dropped in the jungle, with no one to call; (2) they do not know how to treat me; (3) I feel like I'm going to get back in the loop; and (4) self-managing what I know, how I know.

CONCLUSIONS

Similar to other childhood-onset conditions, adolescents and young adults with OI require education and mentorship, and clinicians in the adult healthcare system need to be prepared and supported to receive them. Collective efforts are needed to improve the self-management and transitional care needs for young adults with OI.

Combination therapy in the Col1a2G610C mouse model of Osteogenesis Imperfecta reveals an additive effect of enhancing LRP5 signaling and inhibiting TGFβ signaling on trabecular bone but not on cortical bone

Enhancing LRP5 signaling and inhibiting TGFβ signaling have each been reported to increase bone mass and improve bone strength in wild-type mice. Monotherapy targeting LRP5 signaling, or TGFβ signaling, also improved bone properties in mouse models of Osteogenesis Imperfecta (OI). We investigated whether additive or synergistic increases in bone properties would be attained if enhanced LRP5 signaling was combined with TGFβ inhibition. We crossed an Lrp5 high bone mass (HBM) allele (Lrp5^A214V) into the Col1a2^G610C/+ mouse model of OI. At 6-weeks-of-age we began treating mice with an antibody that inhibits TGFβ1, β2, and β3 (mAb 1D11), or with an isotype-matched control antibody (mAb 13C4). At 12-weeks-old, we observed that combining enhanced LRP5 signaling with inhibited TGFβ signaling produced an additive effect on femoral and vertebral trabecular bone volumes, but not on cortical bone volumes. Although enhanced LRP5 signaling increased femur strength in a 3-point bending assay in Col1a2^G610C/+ mice, femur strength did not improve further with TGFβ inhibition. Neither enhanced LRP5 signaling nor TGFβ inhibition, alone or in combination, improved femur 3-point-bending post-yield displacement in Col1a2^G610C/+ mice. These pre-clinical studies indicate combination therapies that target LRP5 and TGFβ signaling should increase trabecular bone mass in patients with OI more than targeting either signaling pathway alone. Whether additive increases in trabecular bone mass will occur in, and clinically benefit, patients with OI needs to be determined.

Pediatric Outcomes Data Collection Instrument is a Useful Patient-Reported Outcome Measure for Physical Function in Children with Osteogenesis Imperfecta

PURPOSE

Patient-reported outcome measures (PROMs) are increasingly recognized as valuable endpoints in clinical trials. The Pediatric Outcomes Data Collection Instrument (PODCI) is a PROM utilized in children with musculoskeletal disorders. We evaluated the validity and reliability of PODCI in children with osteogenesis imperfecta (OI).

METHODS

Physical functioning and psychological well-being were assessed using PODCI in a large cohort of children enrolled in a multicenter study conducted by the Brittle Bone Disorders Consortium. Physical function scores were correlated with a validated, observer-rated scale, Brief Assessment of Motor Function (BAMF), and with psychological well-being scores. We calculated sample sizes required to detect clinically meaningful differences in physical function.

RESULTS

Four hundred seventeen children with OI types I, III, and IV were enrolled. Physical function scores in OI type III were significantly lower than those in OI types I and IV. There were no significant differences in psychological well-being. PODCI physical function scores showed moderate-to-strong correlation with BAMF. The Global Functioning Scale, a composite of physical function, did not consistently correlate with psychological well-being.

CONCLUSION

PODCI can be a reliable measure of physical functioning in children with OI and offers valuable information about patient-reported health status and new ways to examine the utility of interventions in this population.

Stakeholder views and attitudes towards prenatal and postnatal transplantation of fetal mesenchymal stem cells to treat Osteogenesis Imperfecta

The Boost Brittle Bones Before Birth (BOOSTB4) clinical trial is investigating the safety and efficacy of transplanting fetal derived mesenchymal stromal cells (MSCs) prenatally and/or in early postnatal life to treat severe Osteogenesis Imperfecta (OI). This study aimed to explore stakeholder views to understand perceived benefits or concerns, identify ethical issues and establish protocols for support and counselling. Semi-structured qualitative interviews were conducted with three groups; 1. Adults affected with OI, with and without children, and parents of children affected with OI; 2. Health professionals who work with patients with OI; 3. Patient advocates from relevant patient support groups. Interviews were digitally recorded, transcribed verbatim and analysed using thematic analysis. Interviews with 56 participants revealed generally positive views towards using fetal MSC transplantation to treat OI. Early treatment was considered advantageous for preventing fractures and reducing severity and could bring psychological benefits for parents. Common concerns were procedure safety, short/long-term side effects and whether transplantation would be effective. Difficulties inherent in decision-making were frequently discussed, as treatment efficacy is unknown and, by necessity, parents will make decisions at a time when they are vulnerable. Support needs may differ where there is a family history of OI compared to an unexpected diagnosis of OI. Explaining fetal MSC transplantation in a way that all parents can understand, clear expectation setting, psychological support and time for reflection during the decision-making process will be crucial to allow parents to make informed decisions about participation in the BOOSTB4 clinical trial.

Health-related quality of life in children with osteogenesis imperfecta: a large-sample study

In this large-sample study, we demonstrated that osteogenesis imperfecta (OI) significantly impaired the quality of life (QoL) in children. Moderate/severe OI patients had worse QoL scores than patients with mild OI. Furthermore, the QoL for OI patients was correlated with the presence of pathogenic gene mutations.

INTRODUCTION

Osteogenesis imperfecta (OI) is a hereditary disease characterized by multiple fragility fractures and progressive skeletal deformities. No detailed investigations about the quality of life (QoL) have been carried out in a large sample of patients with OI. We evaluated the QoL and its influencing factors in a large and well-characterized OI cohort.

METHODS

We used a validated questionnaire of PedsQL 4.0 to evaluate the health-related quality of life (HRQoL) of children and adolescents with OI. We compared HRQoL among patients with OI types I, III, and IV. The relationship between HRQoL and pathogenic mutations in candidate OI genes was investigated. We also evaluated the influencing factors of HRQoL in OI patients.

RESULTS

A total of 138 children with OI and 138 healthy controls were enrolled in this study. The HRQoL scores of OI patients were 64.4 ± 30.0, 71.9 ± 22.2, 75.7 ± 24.8, 63.7 ± 24.5, and 68.9 ± 22.0 in physical, emotional, social, school functioning, and total score, respectively, which were significantly lower than those of healthy children (86.5 ± 12.7, 83.3 ± 16.0, 92.1 ± 11.8, 87.5 ± 11.8, and 87.3 ± 10.7, all p < 0.01). Moderate and severe OI (type III/IV) patients had poorer HRQoL scores than patients with mild OI (type I). Gene mutations inducing qualitative defects in type I collagen led to worse HRQoL scores than those with quantitative defects in type I collagen, except in emotional functioning. The total HRQoL score was positively correlated with family income, lumbar, and femoral bone mineral density (BMD) Z-scores and negatively correlated with disease severity and fracture frequency.

CONCLUSION

HRQoL was significantly impaired in OI patients, and patients with more severe OI had poorer HRQoL scores. For the first time, we found that children with qualitative defects in type I collagen had poorer HRQoL scores than those with quantitative defects in type I collagen.

Consensus statement on physical rehabilitation in children and adolescents with osteogenesis imperfecta

On the occasion of the 13th International Conference on Osteogenesis imperfecta in August 2017 an expert panel was convened to develop an international consensus paper regarding physical rehabilitation in children and adolescents with Osteogenesis imperfecta. The experts were chosen based on their clinical experience with children with osteogenesis imperfecta and were identified by sending out questionnaires to specialized centers and patient organizations in 26 different countries. The final expert-group included 16 representatives (12 physiotherapists, two occupational therapists and two medical doctors) from 14 countries. Within the framework of a collation of personal experiences and the results of a literature search, the participating physiotherapists, occupational therapists and medical doctors formulated 17 expert-statements on physical rehabilitation in patients aged 0–18 years with osteogenesis imperfecta.

Pain and quality of life of children and adolescents with osteogenesis imperfecta over a bisphosphonate treatment cycle

The objective was to describe the pain and quality of life among children and adolescents with any osteogenesis imperfecta (OI) type over one intravenous bisphosphonate treatment cycle from a child and parental perspective. A prospective, observational study was conducted, where children and adolescents evaluated their pain intensity, location, and quality, as well as quality of life before, 1 week after treatment, and 6 months later. Quality of life was also evaluated from the parental perspective at the same three time points. Thirty-three child/parent dyads participated. The results showed that pain intensity on the 0-10 self-report scale after the Zoledronate infusion (median = 0, range = 0-6) was not different from pre (median = 2, range = 0-10) and 6-months post-scores (median = 2, range = 0-8) (p = 0.170). Children and adolescents with OI reported experiencing pain mainly in the ankles and the anterior and posterior shoulders. They selected evaluative pain descriptors such as uncomfortable (n = 16, 48%) and annoying (n = 13, 39%). Children and adolescents' functioning and quality of life did not change significantly across the bisphosphonate treatment cycle (p = 0.326), parents perceived an improvement immediately after the treatment compared to before (p = 0.016).

CONCLUSION

Children and adolescents with OI experience mild, yet complex pain localized across several body areas. There is little fluctuation in the pain intensity and functioning of children with OI undergoing bisphosphonate treatment. What is Known: • Acute and chronic musculoskeletal pain remains a major issue in OI. • Pain has a negative impact on quality of life. What is New: • New and unpublished methods and findings describing the pain and quality of life of children and adolescents with OI over one intravenous bisphosphonate treatment cycle from a child- and parental-proxy perspective. • Children and adolescents with OI experience pain intensity that is mild, yet complex in quality and localized across several body areas.

Fatigue and disturbances of sleep in patients with osteogenesis imperfecta - a cross-sectional questionnaire study

Background

Persisting fatigue has been reported to be a common complaint by individuals with connective tissue disorders, including Osteogenesis imperfecta (OI). This controlled study evaluated in an adult OI population the subjective experience of fatigue, affecting daily life. Sleep disturbances and chronic pain were examined as hypothesized underlying factors.

Methods

This cross-sectional study analyzed the answers of 56 OI patients and 56 matched healthy controls to a questionnaire, designed to evaluate levels of experienced fatigue and bodily pain, as well as the presence or absence of symptoms related to sleep disturbances or sleep apnea. The relationships between fatigue, pain, and sleep disturbances were evaluated with correlation analysis and regression analysis.

Results

Fatigue was reported by 96%, and daily pain by 87% of the individuals with OI. Notably, the level of fatigue was similarly experienced by patient respondents and controls. In total, 95% of the patients and 77% of the controls reported one to several sleep disturbance symptoms. These symptoms as well as previously diagnosed sleep apnea were statistically significantly more prevalent in the patient group than in the controls (p < 0.05). Likewise, the experienced bodily pain was statistically highly significantly more severe among the respondents with OI (p < 0.001), and correlated with the reported fatigue.

Conclusions

In comparison with age-matched controls, adults with OI do not differ in experienced fatigue, unlike hypothesized. Therefore, sleep disturbances, which based on the frequency of reported related symptoms and previous sleep apnea diagnoses appear to be common in OI patients, may remain undiagnosed.

Bisphosphonate therapy and osteogenesis imperfecta: The lived experience of children and their mothers

PURPOSE

Osteogenesis imperfecta (OI) is a chronic, genetic condition frequently described as "brittle bones." This condition is expressed by low bone density and characterized by frequent fractures with and without trauma. Additional symptoms include pain, altered growth, and challenges with mobility. This experience has a great impact on the daily life of the child diagnosed with OI and their family. With the introduction of bisphosphonate therapy children diagnosed with OI experienced an increase in bone density that included a change in symptoms and improvement in daily functioning. The purpose of this study was to describe the lived experience of children receiving bisphosphonate therapy for osteogenesis imperfecta (OI) and their mothers.

DESIGN AND METHODS

A phenomenological study was conducted using interviews with a purposive sample of six children diagnosed with OI and their six mothers (N = 12). Children ranged in age from 6 to 18 years. The Giorgi (2009) methodology was used to discover the meaning of living day to day since initiating the bisphosphonate infusion therapy.

RESULTS

Four themes emerged from the synthesis of the meaning units that reflected the experience that bisphosphonate therapy had on daily life with OI. These four themes explicitly described the phenomena being studied and included living daily life in stride; normalcy is living with uncertainty; renewal with infusions; and making choices and living with the consequences.

PRACTICE IMPLICATIONS

Nurses must take an active role in developing and promoting family-centered interventions for transition and support.

Femoral and Lumbar Fractures During Rehabilitation for a Traumatic Spinal Cord Injury in Osteogenesis Imperfecta: A Case Presentation

Osteogenesis imperfecta (OI) is one of the most common inherited bone disorders. These individuals are high-risk for developing fractures during their lifetime secondary to bone fragility. This case presents a female with type I OI involved in a high speed motor vehicle accident resulting in a traumatic spinal cord injury (SCI) and paraplegia. Inpatient rehabilitation was complicated by fractures of the femur and lumbar spine which impacted her level of independence upon discharge to prevent additional fractures and maintain safety. OI coupled with SCI creates a difficult combination for the rehabilitation team. This case highlights the complexity of this challenge to bring awareness to the rehabilitation team in order to safely maximize independence and minimize and prevent unnecessary injury when designing an interdisciplinary treatment plan.

A novel COL1A1 mutation in a family with osteogenesis imperfecta associated with phenotypic variabilities

Osteogenesis imperfecta (OI) is a heterogeneous disorder that is characterized by bone fragility and systemic complications, and is mainly caused by gene mutations in COL1A1 or COL1A2. A novel COL1A1 splicing mutation, c.750+2T>A, was identified in a Japanese OI family. Only the proband in this family showed various complications, such as heart valve diseases and severe scoliosis. The clinical heterogeneity in the family is discussed in this study.
