A Notion of Event Quality for Contextualized Planning and Decision Support Systems

Abstract

This paper presents an approach for contextualizing an event-based decision support system for scheduling patient assessments in a hospital. To cope with unexpected delays, patient coordinators often pursue a worst case scenario when scheduling patient assessments, leading to an underutilization of human resources and equipment when the procedure went without complications. We present a context-based decision support system for patient planning that helps the patient coordinator with taking well-informed rescheduling decisions and anticipating changes in other patients' schedules. The system uses information and events produced by medical equipment. As these events can be nondeterministic, we demonstrate how our domain specific context model can be used to contextualize events to enhance their quality and ascertain their meaning.
