Abstract: Systems and methods for visually displaying instances of increased susceptibility for commission of medical errors are provided. Execution of programming instructions on a computer-readable medium causes a processor to retrieve historical workload data corresponding to environmental conditions experienced by and near misses associated with an individual or team of individuals during a first period of time from one or more data repositories. Retrieved workload data is processed to establish threshold limits for distinct working conditions represented within the workload data for the individual or team of individuals. Workload data corresponding to a second period of time is retrieved for the individual or team of individuals and compared to established threshold limits by the processor. Based on the comparison, the processor generates one or more displayable indicia indicative of the individual's or team of individuals' risk of committing a medical error due to an experienced workload.
