Background: Individuals with rare diseases may face challenges that are different from those experienced in more common medical conditions. A wide range of different rare conditions has resulted in a myriad of studies investigating the specificities of the diagnosis in focus. The shared psychological experiences of individuals with a rare condition, however, have not been reviewed systematically.
Methods: We performed a systematic review, including qualitative studies on adults, published between 2000 and 2016. Papers including more than one rare genetic or nongenetic diagnosis were included. Studies based on single diagnoses were excluded except for four specific conditions: hemophilia (bleeding disorder), phenylketonuria (metabolic disorder), Fabry disease (lysosomal storage disorder), and epidermolysis bullosa (skin disorder).
Results: The review identified 21 studies. Findings were synthesized and categorized according to three main themes: (1) Consequences of living with a rare disorder, (2) Social aspects of living with a rare disorder, and (3) Experiences with the health care system. Findings point to several unique challenges, such as the psychological, medical, and social consequences of a lack of knowledge about the condition in health care and social settings.
Conclusion: The findings highlight the need for more research on the shared psychological and social impact of living with a rare diagnosis across conditions, in order to identify risk factors and inform clinical practice.
