Abstract
Background: Communication about prognosis is a key ingredient of effective palliative care. When patients with advanced cancer develop increased prognostic understanding, there is potential for existential distress to occur. However, the existential dimensions of prognosis communication are underexplored. Objective: To describe the existential dimensions of prognosis communication in naturally-occurring palliative care conversations. Methods: This study was an explanatory sequential mixed methods design. We analyzed a random subset of patients from the Palliative Care Communication Research Initiative (PCCRI) parent study (n = 34, contributing to 45 palliative care conversations). Data were based on audio-recorded and transcribed inpatient palliative care conversations between adults with advanced cancer, their families, and palliative care clinicians. We stratified the study sample by levels of prognosis communication, and qualitatively examined patterns of existential communication, comparing the intensity, frequency, and content, within and across levels. Results: Existential communication was more common, and of stronger intensity, within conversations with higher levels of prognosis communication. Conversations with more prognosis communication appeared to exhibit a shift toward the existential and away from the more physical nature of the serious illness experience. Conclusion: Existential and prognosis communication are intimately linked within palliative care conversations. Results highlight the multiplicity and mutuality of concerns that arise when contemplating mortality, drawing attention to areas of palliative care communication that warrant future research.
