A post-anesthetic discharge scoring system for home readiness after ambulatory surgery
1Department of Anaesthesia, Toronto Western Division, Toronto Hospital, Canada.
Study Objective:
To evaluate the validity and reliability of an objective scoring system, the Post-Anesthetic Discharge Scoring System (PADSS), which was compared against existing Clinical Discharge Criteria in the ambulatory surgery unit of our hospital.
Design:
randomized, open study.
Setting:
Ambulatory surgery unit at a university teaching hospital.
Patients:
247 ambulatory surgery patients undergoing general anesthesia.
Interventions:
One hour after the operation, the initial assessment using PADSS and the Clinical Discharge Criteria was made by an independent observer. Evaluations were repeated at 30-minute intervals until patients obtained a Post-Anesthetic Discharge Score of at least 9 and fulfilled the Clinical Discharge Criteria.
Measurements And Main Results:
There was a close correlation between the end of anesthesia to time patients were fit for discharge using either PADSS or the Clinical Discharge Criteria (Pearson's Correlation Coefficient r = 0.89). The internal consistency reliability of PADSS (alpha = 0.65) was superior to that of the Clinical Discharge Criteria (alpha = 0.14).
Conclusions:
We have found PADSS to have superior measurement scaling and diagnostic properties.
