Statistically significant results of the outpatient group.

Relationship	P value (odds ratio or coefficient)
Increasing age → decreasing duration of surgery	<.01 (−0.98)
Female gender → decreasing duration of surgery	.04 (−9.62)
General anesthesia → increased FAD	.03 (22.21)
TKA → increased FAD	.04 (25.82)
Farther FAD → Farther TAD	<.01 (0.70)
Spinal anesthesia → higher urinary retention incidence	.049 (3.86)
Higher urinary retention incidence → longer PACU length of stay	<.01 (0.36)
Shorter duration of surgery → higher successful discharge rate	.01 (1.07)
Farther FAD → higher successful discharge rate	.01 (1.05)
TKA → higher successful discharge rate	.04 (8.02)

FAD, first ambulation distance; TAD, total ambulation distance.

All of the above relationships are statistically significant.

Odds ratios were used when the dependent variables were categorical data, and coefficients, when the dependent variables were continuous data.

FAD is the distance ambulated on first attempt in PACU.

TAD is total ambulation distance in PACU.
