Robot-guided sheaths consisting of pre-curved tubes and steerable needles are proposed to provide surgical access to locations deep within the body. In comparison to current minimally invasive surgical robotic instruments, these sheaths are thinner, can move along more highly curved paths, and are potentially less expensive. This paper presents the patient-specific design of the pre-curved tube portion of a robot-guided sheath for access to a kidney stone; such a device could be used for delivery of an endoscope to fragment and remove the stone in a pediatric patient. First, feasible two-dimensional paths were determined considering workspace limitations, including avoidance of the ribs and lung, and minimizing collateral damage to surrounding tissue by leveraging the curvatures of the sheaths. Second, building on prior work in concentric-tube robot mechanics, the mechanical interaction of a two-element sheath was modeled and the resulting kinematics was demonstrated to achieve a feasible path in simulation. In addition, as a first step toward three-dimensional planning, patient-specific CT data was used to reconstruct a three-dimensional model of the area of interest.

Nursing Handoff

ObjectiveHandoffs are often framed as the co-construction of a shared understanding relying on narrative storytelling. We investigated how narratives are constructed and used during resident and nurse handoff conversations.MethodWe audio-recorded resident (n=149) and nurse (n=126) handoffs in an inpatient medicine unit. Qualitative analysis using grounded theory was conducted to identify and characterise the structure of resident and nursing handoff narratives.ResultsHandoff conversations among both residents and nurses used three types of narratives: narratives on creating clinical imagery, narratives on coordinating care continuity and narratives on integrating contextual aspects of care. Clinical imagery narratives were common during patient introductions: residents used a top-down approach relying on overarching patient clinical situations (eg, ‘a liver patient’), whereas nurses used a bottom-up approach using patient-specific identifying information. Narratives on the coordination of care continuity for residents focused on managing internal and external coordination activities, whereas nurse narratives focused on internal coordination, emphasising their role as an interface between patients and their physicians. Both resident and nurse narratives on the contextual aspects of care had considerable focus on highlighting ‘heads up’ anticipatory information and personal patient information; such information was often not present in patient charts, but was important for ensuring effective care management.DiscussionThe presence of narrative structures highlights the need for new perspectives for the design of handoff tools that allow for both informational and cognitive support and shared awareness among conversational partners during handoff conversations. We discuss the implications of the use of narratives for patient safety and describe specific design considerations for supporting narrative interactions during handoffs.
