Patient Perspectives on Palliative Care in Pulmonary Arterial Hypertension in the United States.

Palliative care can be offered concurrently as a treatment option to patients with pulmonary arterial hypertension (PAH) to relieve symptoms and improve quality of life. However, it is infrequently used and is associated with misconceptions. Limited studies have reported patients' perspectives of palliative care as a treatment option for PAH. We conducted a web-based survey, informed by a brief targeted literature review and input from patients and clinicians, which was completed by adults (≥ 18 years) in the United States (US) with self-reported PAH. Patients reported demographic and disease variables and their perspectives and experiences with palliative care. Patients self-reported their Pulmonary Hypertension Functional Class Self-Report class, EmPHasis-10, and 6-min walk test. A total of 200 respondents (86.5% female; mean age 58.5 years) from 42 US states completed the survey between 19 September and 3 October 2023. Most respondents described palliative care as "end-of-life care" (n = 43, 25.7%) and associated it with the need for extra support (n = 111, 55.5%). Many respondents (n = 171, 85.5%) had not discussed palliative care services, nor had a palliative care consultation with their healthcare provider (HCP); most had not been offered a consultation (n = 109/171, 63.7%). Despite this low frequency of discussions, respondents reported feeling comfortable discussing palliative care with their HCPs (n = 177, 88.5%). The survey results demonstrated that these patients with PAH had limited experiences with palliative care, where palliative care was frequently subject to misinterpretation. These findings emphasize the need for proactive engagement between patients and HCPs to ensure palliative care is optimally used and understood.
