Figure 2: — Relationship of Sleep disturbance and Opioid Use. A) Preoperative sleep disturbance scores were marginally higher among patient taking opioids at baseline (Mann-Whitney U=1080, p=0.06). At 2 weeks after surgery, disturbed sleep was strongly associated with continued use of opioids to manage surgical pain (Mann-Whitney U=3100, p<0.001) B) Preoperative sleep disturbance score correlated to a larger perioperative opioid requirement (Spearman Rho=0.23, p<.001). MME:Milligram Morphine Equivalents.
