Variation in Communication of Competing Risks of Mortality in Prostate Cancer Treatment Consultations.

Men with prostate cancer prefer patient-specific, quantitative assessments of longevity in shared decision making. We sought to characterize how physicians communicate the three components of competing risks-life expectancy (LE), cancer prognosis, and treatment-related survival benefit-in treatment consultations.

Conversation related to LE, cancer prognosis, and treatment-related survival benefit was identified in transcripts from treatment consultations of 42 men with low- and intermediate-risk disease across 10 multidisciplinary providers. Consensus of qualitative coding by multiple reviewers noted the most detailed mode of communication used to describe each throughout the consultation.

Physicians frequently failed to provide patient-specific, quantitative estimates of LE and cancer mortality. LE was omitted in 17% of consultations, expressed as a generalization (eg, "long"/"short") in 17%, rough number of years in 31%, probability of mortality/survival at an arbitrary timepoint in 17%, and in only 19% as a specific number of years. Cancer mortality was omitted in 24% of consultations, expressed as a generalization in 7%, years of expected life in 2%, probability at no/arbitrary timepoint in 40%, and in only 26% as the probability at LE. Treatment-related survival benefit was often omitted; cancer mortality was reported without treatment in 38%, with treatment in 10%, and in only 29% both with and without treatment. Physicians achieved "trifecta"-(1)quantifying probability of cancer mortality (2)with and without treatment (3)at the patient's LE-in only 14% of consultations.

Physicians often fail to adequately quantify competing risks. We recommend the "trifecta" approach, reporting (1)probability of cancer mortality (2)with and without treatment (3)at the patient's LE.
