On the rise

Audible alarms from infusion pumps, cardiac monitors, ventilators, and other machines constantly compete for nurses’ attention during a shift. More often than not, the message isn’t relevant or actionable. The result can be deadly if a patient’s caregiver becomes desensitized and assumes an alarm is false or misdirected. It’s no secret to nurses or hospital administrators that alarm fatigue is a persistent problem. A 2018 article in the American Journal of Critical Care reported the findings of a clinical alarms survey (conducted at five-year intervals since 2006) to see how the challenge of alarm fatigue is trending. The most recent survey results from over 1,200 nurses and other clinicians are not encouraging, including responses to a key question about so-called “nuisance alarms.” The percentage of respondents reporting that nuisance alarms “occur frequently” has jumped more than 10% in the past five years.




The authors noted that in comparison to prior years, the most recent survey results show a higher proportion of respondents who said their organizations have instituted clinical alarm initiatives and/or alarm management technologies. That’s the good news. However (the bad news), a higher proportion also reported that “nuisance alarms occur frequently, disrupt patient care, and reduce trust in alarms.

How it produces harm


1. Patient safety is at risk

Patient care and monitoring devices (pulse oximeters, ventilators, heart monitors, nurse call systems, infusion pumps, etc.) are critical to alerting caregivers when a patient’s condition changes. But so many alerts are produced every day (a study at Johns Hopkins Hospital found a daily average of 350 alarms per bed) that the sheer number of alerts can quickly become problematic. False positives from loose leads, redundant alerts from poorly set thresholds, and notifications for patients under someone else’s care are just the beginning. Not only are alerts often distracting and difficult to decipher, but they can also be deadly if excessive alarms cause care teams to become desensitized. Common responses to  this issue are to turn down the volume, turn alarms off, or adjust settings outside safe limits—none of which is a desirable solution. For several years, The Joint Commission has addressed alarm fatigue as a patient safety concern by including it as national patient safety goal NPSG.06.01.01: Improve the safety of clinical alarm systems. Managing patient care and monitoring alarms from the variety of systems used today can be a challenging task.

2. Staff retention is at risk

Beyond the risk to patient safety—which is sobering enough—are other negative effects of too many alarms. There is growing evidence that alarm fatigue contributes to clinician burnout. For nurses on today’s hospital units, the complex devices for multiple patients that must be constantly monitored add to an already stressful job. Yet a study from the Association for the Advancement of Medical Instrumentation reported that an amazingly high number of alerts, between 85 and 99%, do not require clinical attention. Caregivers nevertheless are interrupted and must respond in some way. It’s a small wonder that nurses report being desensitized to alarms. Being overwhelmed, stressed, and distracted from patient care also results in reduced job satisfaction.

3. Patient healing is at risk

Too many audible alarms contribute to another issue for hospitals: a too-noisy environment. Whether it’s constant overhead paging or the patient’s own monitors going off, excessive hospital noise inhibits patient healing and recovery. It’s a patient satisfaction issue, too: By a substantial margin, noise is the highest-ranked patient complaint on the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey.

Alarm management

Many hospitals aren’t efficiently using alarm management. Combating alarm fatigue is daunting, but not insurmountable, and there are many steps you can take to reduce alarm fatigue. The latest alarm surveillance technology can filter out nuisance and non-clinically actionable alarms, alert the correct providers or teams, and escalate critical alarms. It’s all about making notifications smarter. Technology that sends alerts to the right person at the right time can reduce the number of non-actionable messages. Through integration with a variety of patient care devices and clinical systems such as ventilators, pulse oximeters, and patient monitors, smart alarms can capture and correlate real-time patient data. Alarm surveillance technology can then analyze the data via established rules:

• Combination alarms – When two or more independent patient measurements violate specific limit thresholds simultaneously.
• Consecutive alarms – When a patient measurement goes in and out of a limit threshold, a given number of times, over a specified amount of time.
• Sustained alarms – When a patient measurement violates a specific threshold for a specified minimum period of time.

The result is more relevant, actionable alarms, as well as a dramatic reduction in the overall number of alarms. Moreover, intelligent software provides escalation for unacknowledged alerts and allows hospitals to maintain a full audit trail of every notification—when it was received, viewed, and responded to.


Get started

Alarm fatigue is a systemic issue, and the response also needs to be systemic. Take the time to ensure your solution addresses all pain points and encompasses people, processes, and technology. Here are some steps to help you get started:

Do your homework

Include all who have a stake in this issue. Use a process improvement team that spans a diversity of disciplines. The entire care team will need to understand, be trained on, and carry out whatever solution they develop. Remember to include non-clinical roles that impact patient care, like biomed techs and health unit coordinators.

Conduct an alarm assessment on each unit. Each unit will have its own set of issues that require unique responses. A comprehensive assessment will give you a better idea of what’s needed to decrease hospital noise on every floor. Don’t assume! If you’re having a lot of lead-fail alarms, fixing your alarm defaults isn’t going to matter: You probably have a problem with your electrode practices.

Clean and monitor equipment. The frequency of monitor alarm sounds can often be reduced by simply cleaning and replacing electrodes, or by ensuring a monitor is working properly. Regularly changing single-use sensors and establishing routine times to inspect, clean, and maintain equipment is a good best practice.

Tailor alerts to patient characteristics. Make a dent in the number of sounding alarms by resetting device parameters for individual patients depending on their specific condition. Alarms that require immediate attention for one patient may not be important for the next, so tailoring parameters will reduce the overall number of alarms as well as alert caregivers to problems that truly need attention.


Alarm surveillance software and mobile access to important patient data improves response

Choose technology

Choose an enterprise-wide mobile alarm management solution. Look for a technology that provides a common alarm management platform across the health system, including biomedical devices, your EHR, and facility devices. Engage your vendor: They may be able to offer capabilities you’ve never considered. With alarm management software, you’re doing more than accommodating staff on the go:

• Get the right message to the right person. By sending alerts (including live waveforms) from patient care monitoring devices directly to the correct care team member’s preferred mobile device (smartphone, Wi-Fi phone, tablet, or pager), you get speedier response times as well as more informed decisions—thus improving patient care.

 Decrease noise, increase patient satisfaction. By bypassing the nursing station and sending secure alerts to the correct on-duty clinician’s mobile device, you can reduce the number of calls and overhead announcements. This minimizes noise and promotes a quieter environment for resting and healing for patients.

• Triage alerts with software. Intelligent clinical alerting software can incorporate your facility’s preset priority levels and use built-in logic to pass along the highest levels of alerts first. Thus, nurses only receive alerts to their mobile device that require immediate attention and are actionable. Further, you can build escalation paths to help ensure critical alarms receive a timely response.

• Decrease clinically inconsequential alerts. Changing a monitor’s thresholds (when appropriate) can cut the number of non-actionable alarms. By switching cardiac monitor thresholds from “warning” to “crisis,” daily audible alarm averages at Boston Medical Center dropped from 12,546 to 1,424—a whopping 89%. This change not only increased nurse responsiveness, but it also dropped noise levels from 92 decibels to 70.

Keep the momentum

Ensure proper training. The sophisticated monitoring devices in use today require staff members to be educated in sensor management, patient skin preparation, customization of alarm parameters, and more. As part of an alarm management plan, your hospital should establish processes to ensure clinical care teams receive continuing education on new and updated devices and protocols.

Measure your progress. Sharing data about alarm reduction, improved message response rate, or faster response time for critical alerts will keep you and your organization on the right path. Metrics will help you refine parameters, improve escalation paths, and find ways to safely reduce non-actionable and nonclinically relevant alarms. You’ll also identify any root causes leading to excess alarms—and thus help identify correctable patient safety issues

Support your process improvement team. These people will help push through the rocky spots, particularly during the tough work of maintenance and continuous education. Their passion for improving patient care (and by extension improving the clinical experience) will keep the initiative on track.

The bottom line

Reducing alarm fatigue is a tough job, a team effort involving all staff. Because the issue involves a complex web of people, communication devices, monitors, and alert sources, it can be easy for your initiative to stall or lose momentum.

Start now (if you haven’t already) and make alarm management a priority to improve patient safety and mitigate provider burnout. Health systems should have an alarm management plan that works today and in the future, since the number of monitoring devices will only increase.

It can be done! As a key issue for all hospitals, alarm fatigue is generating a continual stream of new research, advances in technology, and best practices shared by others from which to learn. Use the information strategically and ensure it all works together for a better healthcare experience for everyone.
