About this study
This is a retrospective chart review to determine the etiologies contributing to prolonged PACU discharge at a major Orthopedic Ambulatory Center
Read the detailed description
Increasing number of surgeries are now performed at ambulatory surgical centers including orthopaedic procedures. While healthier patients usually undergo non-major orthopaedic procedures using regional anesthesia to facilitate faster discharges, prolonged PACU discharges are frequently encountered necessitating characterization and identification of modifiable variables. This is a retrospective chart review to determine the etiologies contributing to prolonged PACU discharge at a major Orthopedic Ambulatory Center.

What is being measured
The primary outcome is the main question the study is designed to answer.
Time required for discharge
This is the length of time that patients stay in the recovery room
Measured: Day of surgery (Day 0) through discharge, average of 6 hours
Secondary outcomes (1)
