The focus of this month's featured article is the intersection of one of the key foundational practices of anesthesia care, intraoperative opioid administration, and administration practice patterns. Using a large dataset from the Multicenter Perioperative Outcomes Group (MPOG), the authors have characterized and quantified variability in intraoperative opioid practice patterns using a Bayesian analysis. Their work demonstrates the significant variability in practice between institutions and forms a strong foundational background for future research in this area. This month's art cover depicts this complex intersection, visually conveying distributions and variability of practice patterns, opioid formulations, and patients.
