Anaesthetist prediction of postoperative opioid use: a multicentre prospective cohort study
Main finding · Opioid use, PACUResult — go to the resultSpearman's rho 0.24 95% CI 0.16–0.33Authors' conclusion
Specialist anaesthetists cannot accurately predict opioid use or dose in the PACU or the first 24 postoperative hours.
Study context
- Population
- Anaesthetist-patient pairs from eight hospitals
- Participants
- 487 anaesthetist-patient pairs
- Exposure
- Anaesthetist-predicted vs actual postoperative opioid use and dose
- Outcome
- Correlation between predicted and actual opioid use and dose (oral morphine equivalents (MEQ)) in the post-anaesthesia care unit (PACU) and first 24 h postoperatively
