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.
