2 NEW MONITORING ALARM CHALLENGES THE ACUTE CARE FLOOR Joseph J. Frassica, MD VP and Chief Medical Information Officer - Philips Healthcare 2

3 Why would we want to monitor patients on the floor anyway? Melbourne: all critical events (cardiac arrest/death/emergency ICU admission) were preceded by warning clinical signs for an average of 6.5 hours MJA 1999; 171: Miami: Cardiac Arrests - 84% had instability for 8 hours prior to the event Chest 1990; 98: Chicago: Of 150 cardiac arrests 99 (66%) had documented instability for 8 hours prior to the event Crit Care Med 1994; 22: Rinaldo Bellomo Live patients are easier to resuscitate than dead ones personal communication 2011 Joseph J.

7 Alarm Sound Exposure in perspective ICU 1 alarm every 92 seconds after intervention Assume: 60 second response time to silence 32 seconds of silence between alarms Alarms don t occur at the same time The math seconds in an 8hr shift sec segments in an 8hr shift seconds with alarm seconds without alarm 166 minutes of silence/ 8 hour shift (2.7 hrs) 313 minutes of alarm sound/ 8 hour shift (5.2 hrs) Monitor Alarm Fatigue: Standardizing Use of Physiological Monitors and Decreasing Nuisance Alarms.

8 Alarm Sound Exposure the reality on the floor Floor One alarm every 38 seconds Assume Response time 60 seconds Every minute there is 38 seconds with one alarm and 22 seconds with 2 alarms One continuous alarm sound an alarm saturated environment 306 minutes of one alarm sounding/ 8 hr shift (5.1 hours) 174 minutes of 2 alarms sounding/ 8hr shift (2.9 hrs) Impact on Caregivers Impact on PATIENTS Joseph J.

12 An opportunity for collaboration MIMIC II (Version 3 - August 2011) 21,422 records - with full-icu stay waveforms and alarms with related physiologic data/documentation and outcomes Discharge DX s Labs Linked to Social Security outcomes DB Publicly available through Physionet Requires reliable annotation Collaboration tools available via Physionet e.g. the MIT-BIH arrhythmia Database 48 fully annotated half-hour two-lead ECGs The gold standard for arrhythmia algorithm development Joseph J. Frassica, MD VP and Chief Medical Information Officer - Philips Healthcare 12

13 An opportunity for collaboration Remaining Gold Standard DB needs Annotated data from various patient populations and settings Inpatient Neonatal Pediatric Obstetrical Joseph J. Frassica, MD VP and Chief Medical Information Officer - Philips Healthcare 13
