Inpatient nurses' preferences and decisions with risk information visualization.
The purpose of this study was to explore the effect of 4 different risk information formats on inpatient nurses' preferences and decisions with an acute clinical deterioration decision-support system. The researchers implemented a comparative usability evaluation in which participants provided responses to multiple user interface options in a simulated setting. Qualitative data was collected using think aloud methods, asking participants which action they would perform after each time point in 3 different patient scenarios. The 6 participants preferred the probability format over relative risk ratios (n = 2), absolute differences (n = 2), and number of persons out of 100 (n = 0). Participants preferred average lines, having a trend graph to supplement the risk estimate, and consistent colors between trend graphs and possible actions. Participants did not prefer too much text information or the presence of confidence intervals. The utilization of the probability format was related with higher concordance in actions taken by participants compared to the other 3 risk information formats.

Effects of workload, work complexity, and repeated alerts on alert fatigue in a clinical decision support system.
In this study, the investigators tested hypotheses arising from two possible alert fatigue mechanisms: (A) cognitive overload associated with amount of work, complexity of work, and effort distinguishing informative from uninformative alerts, and (B) desensitization from repeated exposure to the same alert over time. The investigators found that clinicians became less likely to accept alerts as they received more of them, particularly more repeated alerts. There was no evidence of an effect of workload per se, or of desensitization over time for a newly deployed alert.
