Advancing Strategies to Optimize the PerIopeRativE Management of PostOperative Nausea and Vomiting (ASPIRE-PONV) Trial

The goal of this prospective, unblinded, pragmatic and repeated crossover trial is to learn if clinical decision support alerts will impact postoperative nausea and vomiting (PONV) prophylaxis and reduce PONV rates in adult patients who have planned surgery with general anesthesia. The main aim is to improve PONV, establishing a scalable Clinical Decision Support (CDS) Tool for personalized PONV prevention. The primary hypothesis is that, compared with standard care, the Anesthesia Workflow-Driven Clinical Decision Support Tool for Personalized PONV Prevention will be associated with a significant improvement in the rate of appropriate administration of PONV prophylaxis and a significant decrease in the incidence of PONV. This study will evaluate a new clinical decision support (CDS) tool designed to improve how and when PONV prevention strategies are used. Unlike traditional tools that provide generic, one-time alerts, this new system is integrated into the electronic health record (EHR) and delivers timely, targeted reminders to anesthesia providers at key moments during a patient's surgical care-such as before surgery begins, after anesthesia is given, and before the patient wakes up. These alerts are based on each patient's individual risk for PONV and are intended to support, not replace, clinical judgment. The study will use a crossover design over 12 months, alternating between periods when the tool is active and when it is not. The goal is to determine whether this time-sensitive, workflow-integrated tool can lead to better adherence to best practices and improved patient outcomes.
