High efficiency pathway for lower limb orthopedic surgery: A matched historic cohort study

Table 8 Measured outcomes in pre- and post-matched samples with difference in odds ratios in above ankle procedures, n (%)

Recovery events	Traditional	High efficiency	Traditional	High efficiency	Odds ratio (95%CI)	P value1	E value (5%CL)
Phase 1 recovery utilization, n/total	209 (88.9)	13 (10.8)	98 (84.5)	12 (10.3)	0.022 (0.009-0.049)	< 0.001a	13.0 (8.5)
Opioid utilization, n/total	79 (33.6)	16 (13.3)	44 (37.9)	16 (13.8)	0.26 (0.13-0.52)	< 0.001a	3.3 (2.1)

¹Mann-Whitney U test was used for continuous outcomes and Fisher’s exact test for categorical outcomes.

^aP < 0.05 vs post-matched samples between high efficiency and traditional groups.
