Authors' conclusion

Multimodal analgesia is associated with reductions in opioid charges-specifically inpatient setting-but not various other outcomes.

Study context

Participants
176,225 procedures

Main finding

As reported in the abstract

Opioid charges (OME), inpatients, >2 modes without nerve block vs opioid-only · POD 1

Adjusted % change

−19.4%

95% CI −21.2% to −17.6%

By group

Multimodal analgesia vs Opioid-only analgesia
adjusted % change −19.4% (95% CI −21.2% to −17.6%)

Observational data: associations, not effects.

Further findings

OutcomeAdjusted % change (%) (95% CI)
Opioid charges (OME), total hospitalization, inpatients, >2 modes without nerve blockUnadjusted median OME reductions from 173 to 135 mg−6.0 (−7.2% to −4.9%)

Opioid charges with nerve block added to multimodal analgesia (inpatient and outpatient)

Addition of a nerve block to multimodal analgesia attenuated effects on opioid charges in both settings
