The paramount role of palliative care in low-prevalence diseases

Low-prevalence diseases (LPDs), previously referred to as orphan diseases or rare diseases, entail a substantial potential for mortality and impose a remarkable burden of symptoms for patients. The process of diagnosing these diseases is often lengthy, and viable treatment options for such conditions are scarce, or in some cases, non-existent.

A narrative review was carried out following the Scale for the Assessment of Narrative Review Articles (SANRA) methodology to establish the role of palliative care in the treatment and follow-up of patients with LPDs. A search was carried out by a multidisciplinary team in EMBASE, PUBMED, Web of Science, CINHAL and OVID. Peer-reviewed articles reporting on the role of palliative care in the multidisciplinary treatment of LPDs were included.

The review identified significant areas where palliative care specialists play a crucial role in caring for LPDs. These areas include addressing complex physical and emotional symptoms, assisting patients in adjusting their expectations through genetic counselling, facilitating decision-making across short, medium and long-term perspectives based on disease prognosis, and offering support with care transitions, advanced planning and the grieving process for families.

Patients with LPDs and their caregivers experience complex care needs that should be assessed by a palliative care specialist and supported by a multidisciplinary medical group.
