Randomized Controlled Trial Comparative Study
Effect of a comfort scale compared with a pain numerical rate scale on opioids consumption in postanaesthesia care unit: the COMFORT study.
The way that pain is assessed in the PACU could impact on postoperative pain and analgesic consumption. However, there is currently no evidence to support this speculation. The authors hypothesised that using a comfort scale reduces postoperative opioid consumption when compared with a standard numerical rating scale (NRS) to evaluate pain in the PACU. ⋯ NCT05234216.

The science of pilot trials is evolving, and understanding of their role in medical research is increasing. Perioperative randomised controlled trials often test interventions that are inherently multidisciplinary and complex; therefore, there might be compelling reasons to conduct pilot studies to assess feasibility and inform trial design. As pilot studies themselves require resources, investigators should not squander this opportunity; they should design them so that they properly address the sources of uncertainty regarding the success of the definitive trial.
