Understanding the challenges in alarm management

Management 2013 NPSG Clinical alarm safety for hospitals and
critical access hospitals 2014 Establish alarms as an organization
priority and identify the most important alarms to manage. 2016
Hospitals will be expected to develop and implement specific
policies and procedures for managing alarms as well as educate
staff and independent licensed practitioners in the organization
about alarm system management. Alarm Management Extension
Healthcare performed a marked survey: 90% of hospitals interviewed
havent developed a comprehensive alarm management program 80% of
hospitals interviewed are NOT collecting, reviewing and/or
analyzing alarm data on a regular basis EXCEPT to address sentinel
events. Alarm Management What do we know?
Small percentage of Alarms are actionable Large percentage of
Alarms are non-actionable What does this mean to the Clinician?
Nothing! Whats happened in our institution
University of Maryland Medical Center / Shock Trauma Center We
didnt hear it We couldnt tell what was alarming We just got too
busy Things were just crazy that day The place is like a casino
with so many bells and whistles Alarm Management Alarm Recognition
Cropp et al tested 100 ICU staff (25 physicians, 41 nurses and 34
respiratory therapists) with various degree of ICU experience with
an audiotape of 33 different ICU alarms 3 yr experience correctly
identified 46% of alarms So whats the issue? Lack in education and
training Name that tone. The proliferation of alarms in the
intensive care unit by Cropp AJ Alarm Identification and Response
Simulation Study
Jennifer at UMMC identified a gap in the literature in training new
hired nurseson how to recognizeand respond to different alarms in a
timely manner. Methods: Alarms from multiple devices were recorded
in their natural milieu with multiple alarms captured per recording
and played back to new hires in random order Results: After 14
weeks of training, new hires were able 81 % of alarms Alarm
identification and response simulation study by Jennifer Tumulty
Alarm Management How UMMC began to Manage Alarms?
To manage alarms, have to understand what those are. What are the
defaults and why? Does the department understand the default
impact? We created a mobile lab to understandthe alarms and the
impact of the defaults setting Are the clinicians familiar with
standard monitor features such as alarm levels, sounds and display
Our next step after evaluation of all areas We developed an alarm
estimation software and vital signs dashboards to help clinicians
adjust their setting Understanding the challenges in alarm
management
High resolution vital signs and alarm collection Alarm estimation

collection System
Allow real time capture and long term recording of patient vital
signs, waveforms and alarms Unlimited full disclosure Can capture
and record data from other medical devices such as ventilators,
cerebral oximeters, cardiac output monitor Provides an analysis
tool for the patient vital signs and recorded alarms. High

Technical Alarms CO2 technical alarms: Check Adapter , CAL sensor
and CAL CO2: Nurses lack training on CO2. Medical Center is
training nurses on calibrating CO2 instead of waiting for the
respiratory therapist to do it. ECG technical alarms: Proper skin
prep for ECG electrodes Change ECG electrodes daily What weve
learned Crisis alarms are lowest percentage of all alarms -
actionable All other alarms equal the greatest impact and are non-
actionable Adjusting thresholds should limit alarms Clinicians do
not look at collective data they need acuity or patient specific.
Next steps Should we have individual alarm setting? Vital Signs
Unit dashboard. Do sick patient produce more alarms? Can we use
alarms to predict mortality? Unit Vital Signs Dashboard Unit Vital
Signs Dashboard Target: Reduce 30% alarms in 12 Month
ICU Team ViewerPatent Pending Are Sick Patient Associated with more
Alarms?
610,569 Alarms in 3 Month in 22 Bed Neuro ICU Patients, 28 Expired
Could Alarm status been used in predicting patient outcomes? GCS
UMMC Alarm Task Force Recommendation (ICU/IMC and telemetry
Groups)
Get rid of warning and advisory alarms Default all monitors to full
and not lethal for the arrhythmia alarms Eliminate duplicate
alarms: Use HR high/low instead of bradycardia and tachycardia
Develop a comprehensive education program for all providers Empower
clinicians to customize alarm limits Questions [email protected]
