VINSIA: Visual Navigator for Surgical Information Access

VINSIA: Visual Navigator for Surgical Information Access GQ Zhang1, PhD, Lingyun Luo1, PhD, James Rowbottom2, MD, John Craker2, MSN, Rong Xu1, PhD 1Case Western Reserve University, 2University Hospitals Case Medical Center, OH 44106 Abstract Another way to get information in specific categories are by Category Search, as illustrated in Figure 5 below: We present a graphical, anatomy-driven navigation interface called VINSIA for information delivery at the point of care. VINSIA has been developed by expanding Semantic MediaWiki (SMW [1]) to organize and classify information using four axes: Anatomy, Location, Topic and User. These axes provide the building blocks for faceted information access: any content item in VINSIA can be accessed through any facet with limited need for entering a search term. Preliminary testing of a pilot site demonstrates the feasibility and advantages of VINSIA for high-precision, quick navigation to targeted content items. 1. Click heart area 2. Cleck the Cardiac Valves picture 3. Click Aortic valve 4. Select topic "Clinical Management" Figure 5: Category search Extension Except for Heart, the same procedure can be extended to other anatomies, Below is the Lungs page: Methods Information in VINSIA is categorized into four axes: Anatomy, Location, Topic and User. The Anatomy axis captures the anatomical hierarchy based e.g. on FMA. The Location axis captures physical locations in a hospital setting where the information is used or needed. The Topic axis captures the specific types of information. Finally the User axis captures a hierarchy of user permissions for access control. We use Semantic MediaWiki [1] as the background framework for implementing the axes. For example, to accesscontents specifically on aortic valve, one clicksthe “heart” on the “human body”, followed by theclick sequence “cardiac valves” → “aortic valve”→ “clinical management”(Figure 2). This access mode only involvesmouse clicking without any typing. Figure 6: Lungs page Location Figure 2: Anatomy Navigation System Conclusion VINSIA provides a high-precision, visual, anatomybased navigation interface for clinicians inperioperative and critical care environments. Theefficiency of VINSIA is measured by the total numberof primitive computer interactions (key strokes and mouse drags or clicks). VINSIA is also semanticdrivenbecause of its Semantic MediaWikiimplementation environment. Importing high qualitycontent into VINSIA is a critical prerequisite forfulfilling its function. To support this, VINSIAprovides an interactive interface for qualified users toupload contents and tag them with categories in everyfacet.
