Abstract
CONTEXT: Early palliative care referral is recommended broadly in oncology. Yet, few patients with high-grade gliomas (HGG) - highly aggressive brain tumors - receive specialty palliative care consultation. OBJECTIVES: To delineate unique needs of HGG patients relative to other oncology patients according to perceptions of a diverse sample of US palliative medicine physicians and neuro-oncologists in each of the eight domains of palliative care; and to describe contrasts between physician specialties on indications for and timing of specialty palliative care referrals in HGG. METHODS: Between September 2021 and May 2023, we conducted semi-structured, 40-minute interviews with ten palliative medicine physicians and ten neuro-oncologists. Participants were recruited via purposive sampling for diversity in geographic setting, years in practice, and practice structure. Interviews were audio-recorded, professionally transcribed, and coded by two investigators. Data were analyzed thematically using a qualitative, phenomenological approach. RESULTS: The palliative care needs of HGG relative to other cancers across palliative care domains are distinguished by poor prognosis, physical and cognitive deficits, and neuropsychiatric symptoms. Themes on indications for palliative care referral differed between neuro-oncologists and palliative physicians. Neuro-oncologists favored selective referral for clinical indications such as high non-neurologic symptom burden requiring time-intensive management. Palliative physicians favored early referral of most HGG patients, to allow for maximal benefit across HGG trajectory. CONCLUSION: Patients with HGG have unique palliative care needs that affect palliative care delivery across care domains. Bidirectional education, enhanced collaboration, and consensus guidelines may help overcome barriers to specialty palliative care referral.
