Evaluating a Quality Improvement Initiative to Increase Anesthesia Providers' Use of and Understanding of...

Improved understanding of the monitoring and dosing practices of anesthesia providers regarding neuromuscular blockade is necessary. The use of subjective methods such as peripheral nerve stimulation and clinical assessment tests can increase the risk of residual neuromuscular blockade and adverse postoperative outcomes. Quantitative monitoring of neuromuscular blockade is an alternative tool to peripheral nerve stimulation to guide neuromuscular blockade; however, it is rarely used by providers. We developed an initiative to improve anesthesia providers' knowledge of neuromuscular blockade pharmacology, physiology, monitoring, and management. After the initiative, an analysis assessed for practice change regarding the use of quantitative monitoring and dosing of neuromuscular blocking agents and neostigmine. The use of quantitative monitoring increased significantly from 14.0% in the preinitiative group to 48.0% after the initiative (P < .001). The least squares mean 95% effective dose (ED₉₅) neuromuscular blocking agents dose was compared between pre-initiative and postinitiative groups, and case length was a significant predictor for patients receiving the highest neuromuscular blocking agents doses. Neostigmine doses were compared between preinitiative and postinitiative groups, and body mass index was a significant predictor of the least squares mean neostigmine dose (P = .002) and the likelihood of receiving a high neostigmine dose (odds ratio = 0.911, 95% CI = 0.870-0.955).
