Short acting narcotics (in mcg/kg), mean (std) 2.28 (1.1) 1.86 (1.0) 1.87 (1.0) < 0.0001 0.7883

  1. aThe above table provides unadjusted comparison of compliance measures between the two periods under study: baseline vs intervention and intervention vs post-intervention. Compared to the baseline period, four of the five metrics showed significant improvement during the intervention period. Moreover, all these improvements were sustained during the post intervention period (there were some marginal changes, but none of them were statistically significant). Use of antiemetics, which had already 91.3% compliance during the baseline period, didn’t show significant movement during the intervention or post-intervention period
