Abstract
Our objective was to conduct a scoping review of the literature to inform a modified taxonomy of uncertainty in the NICU, for the purpose of better identifying and defining different experiences of uncertainty for parents and medical teams. We conducted a systematic literature search for studies examining an element of uncertainty in the NICU. Data extraction was guided by Han's taxonomy of uncertainty and a thematic analysis informed the modified taxonomy. We included 55 articles, leading to three major alterations of Han's taxonomy. We believe this modified taxonomy of uncertainty in the NICU provides a more nuanced understanding of the specific uncertainties faced in this context, leading to a better understanding of the different needs of families and medical teams. It also highlights the need for targeted strategies to further explore and manage these uncertainties.
