Abstract: A decision support system provides workflow optimization for healthcare providers. A data repository includes patient profile data and receives real-time patient condition data from a sensor network and workflow data for the provider. The system determines a relative risk value for patients with respect to a negative outcome such as hospital transfer, and defines at-risk patients with respect to the determined negative outcome. Positive outcomes having an inverse correlation with respect to the negative outcome are determined, such as hospice admission without transfer. A clinical workflow is defined as a sequence of treatment stages associated with the determined positive outcome, and provider activity tracked for the at-risk patients with respect to first threshold values, the system further tracking a degree of provider compliance with the clinical workflow stages based on second threshold values.

Abstract: A system for completing a well bore, comprises, a string having a housing having an inner diameter, the housing defining an inner channel, a valve seat having an inner diameter coupled to the housing, a flapper pivotally coupled to the valve seat, the flapper configured to move from a first open position to a second closed position; and a sleeve positioned in the inner channel of the valve seat and configured to retain the flapper in the first open position. The flapper has an arcuate orientation that is generally concentric with the housing when the flapper is in the first open position, the flapper isolates a region of the inner channel of the housing below the flapper from a region of the inner channel of the housing above the flapper when the flapper is in a closed position, and the flapper may move to the second closed position when the sleeve is withdrawn from the inner channel of the valve seat.
