Gabriel et al reported a logistic regression model for predicting extended postanesthesia care following outpatient surgery. The authors are from University of California San Diego.
Patient selection: outpatient surgery
(1) body mass index (BMI) in kg per square meter
(3) scheduled case duration in hours
(4) primary anesthesia type
(5) surgical subspecialty
< 40 kg per sq m
>= 40 kg per sq m
schedule case duration
0.472 * (hours)
monitored anesthesia care
value of X =
= SUM(points for all of the parameters) - 2.426
probability of prolonged postanesthesia care =
= 1 / (1 + EXP((-1) * X))
• The area under the ROC curve is 0.75.
