Adverse Event Reporting
• Manufacturer and User Facility Device Experience (MAUDE) Database• Reports of suspected device-associated:
• Deaths• Serious injuries• Malfunctions
• Mandatory reporting:• Manufacturers, importers, user facilities
• Voluntary reporting:• Healthcare professionals, patients, consumers
10/30/2013 6
Alarm Systems Management Webinar Series
MAUDE Limitations
• Passive Surveillance• Submission of incomplete, inaccurate, or biased
reports• Under-reporting of events
• Cannot establish rates of events• Cannot compare event rates over time or between devices
• Often difficult to establish causality from event descriptions
• Variations in trade, product, and company names complicate searches
• Some information protected from public disclosure
10/30/2013 7
Alarm-Related Reports
• Each adverse event report is assigned one or more:• Device Product Code(s)• Device Problem Code(s)• Patient Problem Code(s)
• Codes are assigned by the reporter• Alarm-related reports were identified by
searching by Device Problem Codes containing the term “alarm” for 2010-2012

Alarm Systems Management Webinar Series
How Do We Get the Data and What Do We Do With It?
• To ensure quality clinical decision support making we need to look at the data
• You do not need to be a clinician or understand medical terminology to retrieve data. You simply need to take ownership
• Where is the alarm data stored? – in primary system or in secondary system
• Who has access to the data? – work with your vendor and business partner to access
• How can the data be retrieved?
10/30/2013 25
How Do We Get the Data and What Do We Do With It?
• How will the data be presented?• Reports• Dashboards
• Begin with a baseline that is simple, and build from there• How many alerts are the nurses receiving per day?
• Compare day-to-day, month-to-month, and even season-to-season• What are the top 3 alerts the nurses are receiving?• Are the top 3 alerts actionable?
• Who will analyze the data?• What will be accomplished with the analyzed data?• Always continue to improve your alarm management program by
analyzing the numbers and through Key Performance Indicators

What the Data Can Tell You• We have confirmed (by analyzing the number of alerts at Kaiser
Permanente Medical Centers) that the industry-leading physiological alerts are consistent with our results1. High Heart Rate = 24%2. Low Heart Rate = 12%3. Sp02 = 12%
• A majority of our heart rates1. 44% >120, but <1252. 33% >45, but <50
• We have also discovered that electrode replacement/hygiene has decreased our alerts by 22%* at our first pilot medical center
• 60 alerts per patient, per day (2.5 alerts per hour)* There may be other factors that account for the decrease, i.e. increased awareness and attention to the issue

Data: What Stands Out? • Understand the difference between alarm signal data
and secondary notification alert data—what stands out for each may vary
• Look at the big picture first and then drill down—total numbers of alarm signals compared to individual alarm signal occurrences
• Which unit(s) have the most alarm signals per patient bed?
• Which alarm signals are the most frequently occurring—across the institution and within a unit?
• Are there ‘patient outliers’?

After the Data: Actionable Versus Non-Actionable?
Actionable Alarm Signal – Requires clinical intervention or some type of action• Life threatening, immediate response and action required• Change in patient status, requires action to reverse or prevent further deterioration• Requires action to correct a technical problem to assure proper patient monitoring,
e.g., leads off, SpO2 sensor disconnected
Non-Actionable Alarm Signal – Does not require a clinical intervention or action• Short duration, self correcting, e.g., SpO2 alarm signal• Intentional, e.g., suctioning or positioning/moving a patient• Triggered due to tight limits rather than actionable ones• False alarm:
• System itself incorrectly identifies an alarm condition• Something interferes with system causing it to detect an alarm, e.g., artifact or
low voltage-triggered asystole
5210/30/2013
Alarm Systems Management Webinar Series
Start With the BasicsElectrode Selection• Select electrodes and lead sets that provide the best continuing signal and adherence
with the least irritation• Electrodes for specific patient populations, e.g., diaphoretic patients
ECG Signal Quality• Select the best lead for monitoring purposes:
• Signal quality (gain, waveform criteria, learned and labeled appropriately)• Patient diagnosis, history, and reason for monitoring (e.g., ischemia or
arrhythmia detection)• Pacemaker identification• Single versus multi-lead monitoring• Assign “Leads Off” as a high-priority alarm
5310/30/2013
Start With the BasicsArtifact Prevention• Skin prep prior to electrode attachment• Electrode storage• Proactive electrode replacement and battery replacement (for telemetry
devices)
Patient and Family Education• Basic but often overlooked or limited• Explain why the patient is being monitored and what the patient can expect• Need to notify staff if electrode becomes loose or electrode or lead set
becomes detached• Importance of not ‘self’ disconnecting or silencing alarms• Talk with nurse if perception that alarms are occurring frequently and/or
impacting sleep or stress level

TechnologyReview and Revise Default Settings/Configurations• Use data to prioritize which settings to address first• Evaluate limits for all parameters—balance limits, not too tight, not too wide—Melanie’s
example of majority of alerts between 120-125, high of 125• Assess if some medium-priority arrhythmia alarms can be defaulted off• Identify redundant settings and determine when they should be utilized or eliminated• Additional settings to review: delay times before an alarm is triggered, e.g., SpO2 low
limit, Desat, Apnea
Optimization• Proactive use of alarm pause/suspend when you know you will trigger an alarm• Monitor standby use• Utilization of NBP alarm suppression for SpO2
• Understand functionality and when to use and when not to, e.g., ST-segment monitoring
• Customization capabilities

Alarm Systems Management Webinar Series
Protocols to Guide Customization Practice and Decrease Non-Actionable Alarms
• These are designed to reduce non-actionable alarms by focusing on when and how to customize alarm settings
• Others to consider:• Monitoring admission criteria• 24-hour monitoring renewal• Transports• Change-of-shift report/handoffs• Daily huddles/rounding with
physician, nurse, and others to do a quick review of current settings and alarms in the past 24 hours
• New hire education and on-going training and competency assessments

Partnering Within Your Facility: Default Settings
• Compare units to assess what/if any variations currently • Use your Alarm Management Committee to evaluate and revise unit
defaults based on patient populations, care models, and data, and to determine which units should have the same defaults
• Test changes incrementally on a pilot unit to assess impact and outcomes
• Establish unit-based Alarm/Technology Champions to assist in implementing final changes, to function as a resource for the staff, to provide a feedback loop for the committee, and to share best practices across units
• Include the nurse managers, and physician and staff representatives from each unit in the decision-making process and to ensure definitions of actionable/clinically relevant are aligned
10/30/2013 61
Partnering Within Your Facility: Who Needs to Hear the Alarm Signals?
• TJC expectation that alarm signals are audible and recognizable above other unit noise
• All staff (clinical, ancillary, physicians, etc.) accountable to ensure alarm signals are acknowledged and responded to – role responsibilities and escalation processes clearly outlined
• With primary alarm systems and notification:• Do walk-throughs to validate that alarm signals can be heard and recognized
anywhere within the unit• If not, explore options (additional audible displays/clients, bedside monitor
capabilities that may allow other patient’s alarm signals to be observed in other rooms, monitor watchers, secondary notification systems)
• With monitor watchers: • What do the units still need to hear?• What alarm signals should the monitor watchers notify staff directly of and how
do they notify them (unit phone, ‘red phone’, overhead page, etc.)?• Escalation pathway for techs if no staff response
6210/30/2013
Alarm Systems Management Webinar Series
Partnering Within Your Facility: Who Needs to Hear the Alarm Signals?
• With secondary notification systems:• Well-thought-out process as to which alerts staff receive (e.g., high-
priority only)? Charge nurse to receive alerts for patients who are inadvertently not assigned in the secondary notification system?
• Decide who receives the alerts (nursing assistant receives leads off and replace battery alerts, respiratory therapy receives ventilator alerts, etc.)
• Does your system allow programmable delays before alerts are received or escalations to others if an alert is not addressed within a certain time frame?
• Use your Alarm Management Committee and other internal experts and resources to assist in evaluating and determining who needs to hear which alarm signals
6310/30/2013
In Conclusion
Any Alarm Management Strategy must be carefully thought out, tested, and continuously evaluated to ensure achieving the right balance of patient safety and quality of care with the reduction/elimination of nuisance alarms and alarm fatigue.
