Background: Hospice is underutilized. Miscommunication, decisional complexity, and misunderstanding around engaging hospice may contribute. Shared decision making (SDM), aided by patient decision aids (PtDAs), can improve knowledge and decision quality. Currently, there are no freely available hospice-specific PtDA to facilitate conversions between patients and providers about hospice care. Objective: To develop a theory-based and unbiased hospice specific PtDA.
