On-line virtual patient learning: A pilot study of a new modality in antimicrobial stewardship education for pediatric residents

Objectives: Our objective was to develop and validate a virtual patient (VP) learning module to educate pediatric residents about antimicrobial stewardship (AMS) principles. A VP module on complicated pneumonia was developed by experts in AMS and pediatric infectious diseases using the online platform DecisionSim™. Decision points were based on AMS principles (diagnosis, antimicrobial selection, dosing, de-escalation, route, duration). Pediatric residents in all training levels at a tertiary pediatric hospital were recruited to test the VP module. Knowledge was assessed via a multiple choice questionnaire. Mean knowledge scores were compared before, after, and 4 months after completing the module using Generalized Linear Mixed Repeated Measures (RM) Analysis. Resident satisfaction was assessed using a validated questionnaire. Results: Seven of 24 pediatric residents (Years 1-4) completed the VP module and pre- and post-module questionnaires. Mean knowledge scores before, immediately after and 4 months after the module were 58.2%, 66.6%, and 71.6%, respectively. The change in knowledge across time was significant (p < 0.001). Residents were satisfied with the module as an AMS learning strategy.
