Patient and family experiences of lysosomal storage diseases in Canada: A qualitative interview study.

Abstract

Canadian patients and families affected by rare genetic lysosomal storage diseases (LSDs) suffer from numerous challenges related to disease management, including issues navigating healthcare and social support services, access to orphan drugs, and intensive treatment regimens. These challenges significantly impact people's quality of life, yet they remain obscure and have not been the subject of comprehensive analysis. Thus, we conducted qualitative interviews with Canadian patients and caregivers living with LSDs to advance current understanding of their experiences with rare-disease (RD) management and health systems navigation to support patient-focused RD policies and programs and improve the health outcomes of the 2.8 million Canadians affected by RDs. This study employed a qualitative descriptive research design with inductive thematic analysis. The study data were collected using semi-structured interviews. Thirty Canadian participants were interviewed in person or remotely via video chat to allow for an interactive discussion and the acquisition of rich data related to the insights and perceptions of people with LSDs. Between April and November 2019, 30 participants (16 patients and 14 caregivers) with experiences with nine types of LSDs and living in seven Canadian provinces were interviewed. Five themes were identified using comprehensive thematic analysis. These themes were the complexity of the diagnosis process; navigation of healthcare systems; psychological, social, and financial implications of LSDs; access to social support services; and access to orphan drugs. Our findings reveal that patients' access to appropriate healthcare and social services is subject to significant delays and lacks care coordination. The process of accessing orphan drugs in Canada is extremely complex and convoluted. The study results also illuminate experiences of RD stigma when navigating healthcare and social support systems. Our study offers new insights into the complex nature and extensive needs of Canadians with LSDs that are currently unmet. The management of these complex diseases requires holistic patient care and support beyond having access to orphan drugs. Our findings highlight the importance of bridging existing gaps between health and social care for RD patients. Policymakers should utilize these results when developing the forthcoming national RD strategy.
