The Identification And Classification Of Flow Disruptions In The Operating Room During Laparoscopic Cholecystectomy And Open Hernia Repair Procedures, Sacha N. Duff

Doctoral Dissertations and Master's Theses

The operating room is one of the most complex work environments in healthcare; it is estimated that at least 7% of adverse events due to medical error occur in the operating room. Flow disruptions are events that cause a "break" in the primary surgical task, or the loss of any team member's situational awareness. An empirical link between flow disruptions and surgical errors in the OR has been established; therefore, identifying and classifying the specific flow disruptions present during different types of procedures should facilitate the development of evidence-based interventions. The goal of this study was to identify and classify …

Effects Of Pack Weight On Endurance Of Long-Distance Hikers, Anthony T. Thomas

Doctoral Dissertations and Master's Theses

Hikers attempting long-distance trails, like the Appalachian Trail, load their backpacks down with gear that may exceed ideal limits on pack weight. Hikers pack clothing to deal with changing weather conditions, sleeping bags, tents, tarps, cooking gear, food, water and other accessories to compensate for the lack of comfort in the remote wilderness. These heavy weights may affect hikers' ability to walk in comfort and result in physical injuries such as ankle sprains, knee pain, muscular fatigue, and soft tissue damage. Heavy pack weights can cause injuries and possibly prevent hikers from completing long distance hikes.
