Primary Outcome Measures:
  • Total ED length of stay [ Time Frame: in the Emergency Department ]

  • Left without being seen (LWBS) rates [ Time Frame: in the Emergency Department ]

Study Completion Date: December 2007
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Control
regular use of the 2-bed areas in the Emergency department
Behavioral: Clinical Decision Unit
a dedicated 2-bed area to see patients and then rotate them back into the waiting room area for labs and diagnostic imaging.

Detailed Description:
The study will take place over a 6-week period that will be spilt into three-two-week blocks. Using computerized blocks of 2 weeks, days of the week will be randomly allocated so that each day of the week receives one intervention (CDU) and one control day for the study period. The CDU involves transforming an ED bed location to a 6-chair internal waiting room with 2 adjacent beds assigned to act as assessment and treatment locations. Patients will transition between the chair and stretcher to optimize the use of ED space.
