BACKGROUND Many patients with atrial fibrillation (AF) do not receive oral anticoagulants (OAC) for the prevention of stroke and systemic embolism. We aimed to improve the prescription of (OAC) among hospitalized patients with AF. METHODS AND RESULTS We developed a computer-based electronic alert system for identifying hospitalized OAC-naïve patients with AF. The alert system contained a CHA2...

OBJECTIVE To investigate the efficacy of capacity alert calls in reducing acute hospital overcrowding through addressing rising occupancy, high patient throughput and increased access block. METHODS Retrospective analysis of 24 months of in-patient, emergency department, and capacity alert call log data from a large metropolitan public hospital in Australia. The analysis explored statistical ...

As for network security, post-IDS alert analysis has become a fashion in view of collaboration and correlation, and context-aware alert verification is one of the main solutions. In order to guarantee a unified representation of related information and knowledge, this paper tries to introduce basic-elements and the extension method into the study on context-aware alert verification. This paper ...

BACKGROUND Most evaluations of epidemic thresholds for influenza have been limited to internal criteria of the indicator variable. We aimed to initiate discussion on appropriate methods for evaluation and the value of cross-validation in assessing the performance of a candidate indicator for influenza activity. METHODS Hospital records of in-patients with a diagnosis of confirmed influenza we...

BACKGROUND Clinical decision support systems, including electronic alerts, ideally provide immediate and relevant patient-specific information to improve clinical decision-making. Despite the growing capabilities of such alerts in conjunction with an expanding electronic medical record, there is a paucity of information regarding their perceived usefulness. We surveyed healthcare providers' opi...

Background—In 1995, the Bypass Angioplasty Revascularization Investigation (BARI) found that patients with diabetes had a survival benefit when treated with surgical revascularization versus balloon angioplasty, prompting a National Heart Lung and Blood Institute (NHLBI) “Clinical Alert.” The influence of the BARI findings and of the Clinical Alert on practice patterns is unknown. Methods and R...

Intrusion/misbehavior detection and response are two important components for defending against various attacks in mobile ad hoc networks. Unfortunately, there is a gap between local intrusion/misbehavior detection and network-wide response in such networks. To bridge this gap, alert propagation, aiming to spread alert messages to the whole network upon detection of malicious/abnormal activity,...
