Hospitals' New Issue: A 'Glut' of Machines Making Alarm Sounds (fiercehealthcare.com) 77

"Tens of thousands of alarms shriek, beep and buzz every day in every U.S. hospital," reports Fierce Healthcare -- even though most of them aren't urgent, disturb the patients, and won't get immediate attention anyways: The glut of noise means that the medical staff is less likely to respond. Alarms have ranked as one of the top 10 health technological hazards every year since 2007, according to the research firm ECRI Institute. That could mean staffs were too swamped with alarms to notice a patient in distress or that the alarms were misconfigured. The Joint Commission, which accredits hospitals, warned the nation about the "frequent and persistent" problem of alarm safety in 2013. It now requires hospitals to create formal processes to tackle alarm system safety...

The commission has estimated that of the thousands of alarms going off throughout a hospital every day, an estimated 85% to 99% do not require clinical intervention. Staff, facing widespread "alarm fatigue" can miss critical alerts, leading to patient deaths. Patients may get anxious about fluctuations in heart rate or blood pressure that are perfectly normal, the commission said....

In the past 30 years, the number of medical devices that generate alarms has risen from about 10 to nearly 40, said Priyanka Shah, a senior project engineer at ECRI Institute. A breathing ventilator alone can emit 30 to 40 different noises, she said... Maria Cvach, an alarm expert and director of policy management and integration for Johns Hopkins Health System, found that on one step-down unit (a level below intensive care) in the hospital in 2006, an average of 350 alarms went off per patient per day -- from the cardiac monitor alone.... By customizing alarm settings and converting some audible alerts to visual displays at nurses' stations, Cvach's team at Johns Hopkins reduced the average number of alarms from each patient's cardiac monitor from 350 to about 40 per day, she said.

Hospitals are also installing sophisticated software to analyze and prioritize the constant stream of alerts before relaying the information to staff members.

    And of course there's the story of the overworked intern (yours truly) who was on call at the ER and was called to the ward by nursing to confirm that a 90 patient had indeed died. As per procedure said intern hooked the patient up to a monitor to confirm the lack of electrical activity of the heart. Then said intern returned to the ER to continue with the rest of the patients. 2 hours later I get another call from the nurses on the ward saying "Doc, are you ever going to come back and disconnect that monitor? It's just the other patients are getting really spooked by staring at that flat line...."

    My wife had two six-day stretches of hospitalization during November. Most of this time was in a regular room, with about one-third of the time in the ICU. Both locations were crammed with electronic gear, some element of which found a reason to beep loudly every few minutes. There was even a loud alarm built into the bedside chair that sounded off whenever I had been sitting in it and got up, the rationale being that at times when the patient sits in that chair, staff needs to know if they might have fallen off it.

    If a loud repetitive beep is supposed to summon help, why doesn't it bring an immediate response? And if the problem isn't immediate, why does the device need a loud warning? Why can't error conditions be quietly reported to the charge nurse desk, where screens are being continuously monitored?

    My impression of the slow response to machine alarms was that because the same cacophany is coming from every other room in the pod, nurses have to prioritize their responses.

    • Alarms should be reported to a central station with a person assigned to monitor them continuously and make sure important ones are not ignored. This would require all devices to be networked though, which raises costs and complexity. Many devices are already networked (pumps of many kinds) though. Liability may be one reason the alarms have not been centralized. If a patient is harmed those responsible can say they didn't hear the alarm amongst the many others. If there is a central station that logs
