Existential uncertainty in the patient cancer experience: Delimiting the concept.

Objective: To delimit the concept of existential uncertainty in the patient cancer experience from other, related aspects of uncertainty in the context of an existing framework of health-related uncertainty.

Methods: In-depth interviews were carried out with six people living with cancer and analyzed using theory-driven, concept-focused thematic analysis.

Results: Our analysis suggests that existential uncertainty is concerned with meaning rather than information; with the person rather than the disease; and with the fundamental nature of our human being-in-the-world rather than the more practical aspects of our relationships with others. Patient expressions of existential uncertainty may involve a nonscientific discourse of metaphor, analogy, and imagination.

Significance Of Results: It is important for professionals working in supportive oncology to have a conceptual understanding of uncertainty in order to choose how best to respond to patients' needs, as different interventions may be more or less appropriate to different aspects of patient uncertainty.
