A Randomized Controlled Trial of Specialty Palliative Care to Improve Health-Related Quality of Life in Pulmonary Arterial Hypertension.

Pulmonary arterial hypertension (PAH) is associated with significant symptoms and impaired health-related quality of life (HRQOL) and survival. Specialty palliative care (SPC), an intervention delivered by a multidisciplinary team, is focused on improving HRQOL. We performed a randomized controlled trial (RCT) of SPC among adults with PAH and impaired HRQOL to determine the impact of SPC on HRQOL as assessed by PAH-SYMPACT. PAH-SYMPACT is a validated PAH disease-specific patient-reported outcome measure that assesses HRQOL across four domains: cardiopulmonary symptoms, cardiovascular symptoms, physical impact, and cognitive/emotional impact. Sixty-two patients were included (36 usual care, 26 SPC plus usual care), but only 58% of patients randomized to SPC completed their SPC visits. In the intention-to-treat analysis, SPC was associated with similar changes in total, symptom, and physical impact domain scores and increased cognitive/emotional impact scores, indicative of worse HRQOL. In the per-protocol analysis, SPC was not associated with significant changes in total or individual domain scores. According to a survey of patients who completed SPC visits, most were satisfied with their visit and were likely to recommend SPC for other patients with PAH. In conclusion, limited SPC visits in this single-center RCT were not associated with significant improvements in HRQOL among patients with PAH and impaired HRQOL, but the majority of patients who participated in a SPC intervention were satisfied and would recommend SPC to other PAH patients. Future studies of SPC in PAH are needed to determine the appropriate patient selection and timing for SPC. www.clinicaltrials.gov (NCT03905421).
