Transitions of Care in Patients With Inborn Errors of Immunity

Inborn errors of immunity (IEI) are a group of inherited conditions caused by damaged monogenic variants that result in impairment and/or dysregulation within the immune system. IEI are typically diagnosed in infancy or early childhood, with clinical presentations that include increased susceptibility to infections, immune dysregulation, autoinflammation, bone marrow failure, and/or malignancy. Historically, transitions of care experienced by patients with IEI have not been well described in the literature. However, with treatment advances extending the long-term survival of patients, this has become a primary area of research. It is crucial to establish guidelines and recommendations specific to the transition of patients with IEI. Transitions may include patients who naturally progress from pediatric to adult care, from inpatient to outpatient settings, or from their established health care team to a new team (ie, moving from one geographic area to another). This narrative review summarizes the current data on transitions of care and describes the health care challenges and patient-related barriers impacting transitions of care. Frameworks with practical guidance on how health care practitioners can better manage care transitions faced by patients with IEI are presented.
