This year's challenge is 'Reducing False Arrhythmia Alarms in the ICU'. False alarms in the ICU can lead to a disruption of care, impacting both the patient and the clinical staff through noise disturbances, desensitization to warnings and slowing of response times, leading to decreased quality of care. To address this issue, competitors are challenged to devise a method of processing all the available data to reduce false alarms with minimal or no effect on true (vital) alarms. http://physionet.org/challenge/2015/ PhysioNet 20150215.1 Challenge 31 January 2015 12:00:00 AM EDT Two new software packages have been added to PhysioToolkit!
