Insights
Parents face many challenges accessing expert care for children with complex vascular malformations (VMs). Identifying these barriers and facilitators is crucial for improving treatment and health outcomes for these rare disorders.
Area of Science:
- Medical Genetics
- Pediatric Medicine
- Vascular Biology
Background:
- Complex vascular malformations (VMs) are rare, debilitating conditions impacting children.
- These disorders can lead to pain, coagulopathy, disfigurement, and disability.
- Delayed or incorrect diagnosis and treatment worsen patient health outcomes.
Purpose of the Study:
- To identify factors impeding or facilitating access to expert care for children with complex VMs.
- To understand parental perspectives on navigating healthcare for these rare disorders.
- To inform interventions aimed at improving care delivery for affected families.
Main Methods:
- Semi-structured interviews were conducted with 24 parents of children with complex VMs.
- Thematic analysis was used to identify barriers and facilitators to expert care access.
- Participants were recruited through patient advocacy groups for CLOVES Syndrome and Klippel-Trenaunay.
Main Results:
- Eleven factors across six themes influence access to and maintenance of care.
- Key themes include individual, healthcare system, and clinical characteristics.
- Access to information about VMs and their care emerged as a crosscutting factor.
Conclusions:
- Parents report numerous factors affecting their ability to provide optimal care for children with VMs.
- These identified factors can guide future interventions to enhance care delivery.
- Improving access to expert care is vital for managing complex vascular malformations.
Background:
Complex vascular malformations (VMs) are rare disorders that can cause pain, coagulopathy, disfigurement, asymmetric growth, and disability. Patients with complex VMs experience misdiagnosis, delayed diagnosis, delayed or inappropriate treatments, and worsened health. Given the potential consequences of delaying expert care, we must identify the factors that impede or facilitate this access to care.
Results:
We performed semi-structured interviews with 24 parents (21 mothers; 3 fathers; median age = 42.5 years) of children with complex VMs and overgrowth disorders living in the US, recruited through two patient advocacy groups - CLOVES Syndrome Community, and Klippel-Trenaunay Support Group. We performed thematic analysis to assess parental perspectives on barriers and facilitators to accessing expert care. We identified 11 factors, representing 6 overarching themes, affecting families' ability to access and maintain effective care for their child: individual characteristics (clinician behaviors and characteristics, parent behaviors and characteristics), health care system (availability of specialist multidisciplinary teams, care coordination and logistics, insurance and financial issues, treatments and services), clinical characteristics (accuracy and timing of diagnosis, features of clinical presentation), social support networks, scientific progress, and luck and privilege. Additionally, access to information about VMs and VM care was a crosscutting theme affecting each of these factors. These factors influenced both the initial access to care and the ongoing maintenance of care for children with VMs.
Conclusion:
Parents of children with VMs report multiple factors that facilitate or impede their ability to provide their child with optimal care. These factors represent possible targets for future interventions to improve care delivery for families affected by VMs.
