Improving neuromuscular monitoring and reducing residual neuromuscular blockade via e-learning: A multicentre interrupted time-series study (INVERT study)

Abstract

Background: Neuromuscular monitoring should be applied routinely to avoid residual neuromuscular block. However, anaesthetists often refrain from applying it, even when the equipment is available. We aimed to increase neuromuscular monitoring in six Danish anaesthesia departments via e-learning. Methods: Interrupted time series study, with baseline data from a previous study and prospective data collection after implementation of the module, which was available for 2 weeks from 21 November 2016. We included all patients receiving general anaesthesia with muscle relaxants until 30 April 2017. Main outcome was application of acceleromyography, grouped as succinylcholine only and non-depolarising relaxants. Secondary outcomes were last recorded train-of-four ratio (non-depolarising) relaxants and score on a ten-question pre- and post-course multiple-choice test. Results: The post-intervention data consisted of 6525 cases (3099 (48%) succinylcholine only, 3426 (52%) non-depolarising relaxants). Analysing all departments, we found a positive pre-intervention trend in application of acceleromyography for both groups, of estimated 7.5% and 4.8% per year, respectively (p
