When the Unknown Is Unknowable: Confronting Diagnostic Uncertainty

Abstract

The neonatology literature often refers to medical uncertainty and specifically the challenges of predicting morbidity for extremely premature infants, who can have widely varying outcomes. Less has been written about situations in which diagnoses are simply unknown or unattainable. This case highlights the importance of communication amidst uncertainty from a lack of knowledge about aspects of a patient’s condition. Using epidemiologic and clinical reasoning, the authors challenge the assumption that diagnostic uncertainty must necessarily portend prognostic uncertainty. When physicians’ quest for a diagnosis becomes burdensome and detrimental to the infant’s quality of life, this should be abandoned and replaced by focusing on prognosis. The authors focus on the shift of the physician’s role toward one of support, assisting the family in ascribing meaning to the dying experience. By focusing on prognosis and support, communication can proceed with more clarity, understanding, and empathy.
