Objectives
▪ Define the concept of “alarm fatigue” and factors that contribute
to it’s occurrence
▪ Discuss a comprehensive clinical alarm assessment, policy and
educational strategy that improve alarm safety while meeting
regulatory requirements
▪ Identify essential provisions and timelines for implementation of
The Joint Commission’s National Patient Safety Goal for alarm
management
Responding to Alarms
Alarm sounds . . . . . .
▪ Hear the alarm
▪ Determine meaning/interpret
▪ Prioritize if immediate action necessary
▪ Distinguish what action is appropriate
▪ Respond
▪ Patient care – resuscitation response, notifications
▪ Adjust monitor parameters/fix equipment
How Do Alarms Work?
▪ Current Designs
▪ High sensitivity – detect even minute changes = frequent alarms
▪ Low specificity – do not distinguish if real or important = frequent alarms
▪ Threshold Technology
▪ Each alarm has a threshold that must be breached for it to sound
(e.g., low HR at 50 bpm)
▪ Each alarm as a separate threshold (HR vs SBP vs SpO2)
▪ Thresholds may not be integrated (e.g., asystole alarm & A-line BP 110/72)
▪ Built in delays for “self correction” prior to alarm are possible
▪ Current Options to Reduce Alarms Include
▪ Disabling the parameter
▪ Changing the threshold
▪ Increasing the delay
The Problem With Alarms
▪ Ranked as #1 top technology safety hazard by ECRI
(Economic Cycle Research Institute)
▪ 86% - 99% of alarms are non-actionable
▪ Fire alarms work because they are a RARE event!
▪ When the same alarm sounds for a life threatening
arrhythmia versus brushing your teeth, then
“Nothing is an Emergency”

Alarm Fatigue Terminology
Actionable Alarm – Requires intervention
▪ to reverse or prevent patient deterioration
▪ to maintain appropriate monitoring, avoid missing critical events
Non-actionable [nuisance] alarm – Does not require intervention
▪ True: alarm was accurate but unimportant
▪ False: alarm error (e.g., artifact)

Internal Alarm Frequency Audit Strategy
3 campuses, 11 units
9,515 alarms/day
▪ Set up “event groups” at each central station (once then save groups)
▪ Event group = red arrhythmia, yellow arrhythmias (3), discharge (hi/lo HR), all alarms
▪ Patient window → all controls → unit settings → event groups → new group/name
▪ Review and collect individual patient data
▪ Patient window → alarm review → event review → select 24 hrs → select event group
▪ Tally by unit

Potential Adverse Consequences of ECG Monitoring
▪ Alarm fatigue!
▪ Resource utilization
▪ Nursing hours and ratios
▪ Disposables
▪ Equipment maintenance and upkeep
▪ Reduced mobility for the patient
▪ Increased time in bed
▪ Potential delirium, PNA, etc.
▪ Patient & family concerns of being “critically ill”
▪ Misinterpretation of artifact as VT
Artifact Mimicking Ventricular Tachycardia
FROM: Knight BP, et al. NEJM 1999; 341(17):1270-1274.
This patient was treated with lidocaine
Drew showed that 86.8% of VT alarms are FALSE!
Evidence Based Criteria for Telemetry Monitoring
▪ Class I – Indicated for nearly all acute patients
▪ Potential for ischemia (ACS, high risk CAD)
▪ Potential for arrhythmia (post arrest, drug load, > Mobitz II heart block, etc)
▪ Procedural or critically ill (postop heart, PCI, conscious sedation, etc)
▪ Class II – Indicated for some patients
▪ Potential for instability (chest pain, syncope, hypotension, etc)
▪ Class III = Monitoring is not indicated
▪ Acute conditions (low risk surgery, terminal illness, atypical chest pain, etc)
▪ Chronic, stable conditions (atrial fib, asymptomatic PVCs or NSVT, etc)

System-Wide Alarm Policy
POLICY AND PURPOSE
Alarm management is a Joint
Commission National Patient Safety
Goal (NPSG.06.01.01) that this
organization has identified as a priority.
Clinical alarm systems are intended to
alert caregivers to an important change
in the patient's physiologic condition or
a medical device equipment issue and,
if not managed properly, can
compromise patient safety.
Alarm Priority Levels
Risk/Priority
Criteria
Response Time
Level of Oversight
High
•
•
Potentially life-threatening, audible alarms
Inattention could result in permanent harm or
death
Immediate
Goal <2 minutes
Need for close observation of
patient and device all or most of
time*
Moderate
•
Not life-threatening, medium priority, audible
warning
Non-emergent; requires attention as quickly as
possible
Rapid
Goal 2-5 minutes
Need for close observation of
patient and device many times
throughout shift
No harm to patient if evaluated within short time
period
Audible advisory signal indicates need for
reassessment
As soon as
possible
Goal 5-7 minutes
No need for intervention throughout
shift anticipated or patient harm if
unattended

Staff Responsibilities For Alarm Safety
▪ Critical clinical alarm systems will not be disabled. Patient care staff will check all
equipment with clinical alarms to ensure:
▪
▪
▪
▪
Settings are appropriate for each patient;
Alarm is active;
Alarm is not impaired in any manner;
Alarm is sufficiently audible to all staff with respect to distance and competing noise
▪ Caregivers and equipment users will verify, as appropriate, that critical alarms are in the
"On" position and sufficiently audible:
▪
▪
▪
▪
Prior to using the device on a patient;
When assuming care of a patient (i.e., at the start of shift);
Following removal and subsequent reapplication of the device on a patient;
Prior to transferring a patient with the device to another care area.
Alarm Fatigue Summary
▪ Alarm management is an important problem that creates
safety risks, leading to a new national patient safety goal
▪ Use of internal alarm data is essential to target highest
priority alarms and improve outcomes
▪ Implementation of evidence-based practices is effective in
reducing nuisance alarms while improving safety
▪ The Joint Commission NPSG will require us to do more in
2015 and beyond to address this issue
