Benefits of simulation for ultrasound-guided midline placement training: MC-in-Sim pilot study

Abstract

Introduction: Ultrasound-guided placement of Midlines catheters (MCs) is a standard procedure with many benefits for patients. Even if there are some guidelines worldwide, this invasive technique is still taught at the patient’s bed and relies on mentoring in many care centers. The performance of this care by novice practitioners raises ethical and quality of care issues mainly because of its risk of complications. This study aimed to propose and assess a simulation-based learning method for the placement of MCs in novice practitioners. Methods: A single-center prospective observational study was conducted with anesthesia residents who had no prior experience of Midline placement. Two workshops were planned. The first one consisted of a theoretical training and a simulated practical phase. The second workshop included an assessment of theoretical memorization, a practical exercise and adherence to the training program. Results: The median score of the theoretical memorization was 14.6 (interquartile range [IQR]: 13.5–15.8). The MCs placement time was significantly higher (Med: 12.23 min; IQR: 12.21–12.80) for novice practitioners who did not successfully complete solo MCs placement in simulation versus novice practitioners who successfully completed solo MCs placement in simulation 6.66 min (IQR: 5.92–8.93) ( p = 0.002). The number of attempts was significantly higher ( p = 0.034) for the novice practitioners who did not successfully complete solo MCs placement in simulation with 67% having performed three punctures, against 0% for the novice practitioners who successfully completed solo MCs placement in simulation. All novice practitioners found this training model efficient for learning how to place MCs and considered it allows for reproducibility in care situations. Conclusion: This ultrasound-guided MCs training on simulation is an agile and fast alternative to traditional bedside training for anesthesia novice practitioners.
