Background. Remote simulation training provides a unique opportunity to captivate providers despite language, distance, and cultural barriers. Previously we developed a novel electronic decision support and rounding tool, the Checklist for Early Recognition and Treatment of Acute Illness in Pediatrics (CERTAINp). This study was conducted to determine the feasibility and impact of remote simulation training of international PICU providers using CERTAINp. Methods. We conducted train-the-trainer sessions in 7 hospitals based in 5 countries (China, Congo, Croatia, India, and Turkey) between 11/2015 and 11/2016. Providers first took part in a base line simulation session to assess their clinical performance. They had structured hands-on training using CERTAINp, which was done remotely using video conference with recording capabilities. Performance in PICU “admission” and “rounding” scenarios was assessed by their adherence to standard of care guidelines using CERTAINp. After this training, the providers were re-evaluated for performance using a validated instrument by 2 independent trained reviewers. Results. A total of 7 hospitals completed both baseline and post simulation sessions. We observed improved critical task (total 14) completion in the admission scenarios where pre training task completion was 8.2 ± 2.6, while after remote training was 11.2 ± 1.8, P = .01. In rounding scenarios, compliance to standard of care guidelines improved overall from 45% to 95% ( P < .01). Conclusion. We observed an improvement in compliance for measures determined as best practice guidelines in simulation rounding and overall improvement in critical tasks for simulated admission cases after remote training.
