ESSENCE created visualizations on average 89% faster than previous methods, requiring 43% fewer computational steps. For the production of reports ESSENCE was 86% faster, requiring only 4.55 minutes compared to 27.83. For tasks relating to PH responses, initiating ad hoc ED surveillance was 96% faster through ESSENCE without comparing resource savings during follow-up monitoring. However, conducting QI reviews was faster using previous systems with modules designed for such tasks. ESSENCE also reduced the need for staff training, as one system was used for most tasks instead of five (Excel, ArcGIS, Access, SAS/SPSS and Merlin).
