The technique of spatial modulating (“jittering”) an existing or newly created auditory alert along a virtual trajectory to improve its detection in a noisy environment is described. Threshold data from 14 participants were gathered as a function of spatial modulation rate (0, 1.6 and 3.3 Hz) of an avionics “wind sheer” alert (two successive 300 ms square waves) against a steady state backgroun...

BACKGROUND Clinical decision support systems can prevent knowledge-based prescription errors and improve patient outcomes. The clinical effectiveness of these systems, however, is substantially limited by poor user acceptance of presented warnings. To enhance alert acceptance it may be useful to quantify the impact of potential modulators of acceptance. METHODS We built a logistic regression ...

BACKGROUND Electronic prescribing is increasingly used, in part because of government incentives for its use. Many of its benefits come from clinical decision support (CDS), but often too many alerts are displayed, resulting in alert fatigue. OBJECTIVE To characterize the override rates for medication-related CDS alerts in the outpatient setting, the reasons cited for overrides at the time of...

The area of alert fusion for strengthening information assurance in systems is a promising research area that has recently begun to attract attention. Increased demands for “more trustworthy” systems and the fact that a single sensor cannot detect all types of misuse/anomalies have prompted most modern information systems deployed in distributed environments to employ multiple, diverse sensors....

Intrusion Detection Systems (IDS) secure all kinds of IT infrastructures through automatic detection malicious activities. Unfortunately, they are known to produce large numbers alerts that often become overwhelming for manual analysis. Therefore, aggregation methods have been developed filtering, grouping, and correlating alerts. However, existing techniques either rely on manually defined att...

20 Background. Electronic Health Record (EHR)-based sepsis alert systems have failed to 21 demonstrate improvements in clinically meaningful endpoints. However, the effect of 22 implementation barriers on the success of new sepsis alert systems is rarely explored. 23 Objective. To test the hypothesis time to severe sepsis alert acknowledgement by critical care 24 clinicians in the ICU setting w...

BACKGROUND Confidence in intraoperative neurophysiologic monitoring (IONM) data can allow scoliosis surgeons to proceed with surgery even after a monitoring alert, assuming the recovery of signals. We sought to determine the outcomes of surgical treatment of adolescent idiopathic scoliosis (AIS) after a notable IONM alert. METHODS We identified 676 patients who underwent arthrodesis with use ...

OBJECTIVES To reveal differences in drug-drug interaction (DDI) alerts and the reasons for alert overrides between admitting departments. METHODS A retrospective observational study was performed using longitudinal Electronic Health Record (EHR) data and information from an alert and logging system. Adult patients hospitalized in the emergency department (ED) and general ward (GW) during a 46...
