A Study of Silent Alarm Delivery Versus Standard Audible Alarm Delivery in Intensive Care and High Dependency Units
India223 participantsStarted 2026-02-03
Plain-language summary
The goal of the trial is to learn if a strategy to eliminate audible alarm noise in intensive care and high dependency units can reduce overall noise levels, patient delirium, staff alarm fatigue, and staff burnout. Researchers will implement a silent alarm strategy in specific care units for four weeks and compare this to a separate 4 weeks where a silent strategy is not implemented. Noise, burnout, delirium levels, and staff alarm response times will be compared between the silent and non-silent units.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial looked at whether sending alarms silently — rather than as audible sounds — affected rates of delirium in the ICU, measured using something called the CAM-S scale; can you explain what that means for how my own mental state would be monitored if I were in an ICU setting?
2Since the trial has already been completed, have the results been published yet, and if so, what did they show about whether silent alarm delivery actually reduced delirium or just changed noise levels?
3The study also measured 'alarm fatigue' in ICU nurses — meaning nurses becoming desensitized to too many alarms — so how might that phenomenon affect the quality of monitoring I'd receive as a patient in your unit right now?
4Given that this was a Phase NA (non-drug) study about how alarms are delivered rather than a treatment for any specific condition, does your ICU already use silent or pager-based alarm systems, or is the standard audible alarm approach still in place?
5If reduced ICU noise genuinely lowers the risk of delirium, are there other steps your team currently takes to protect patients from noise and sleep disruption that I should know about before any planned ICU stay?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Confusion Assessment Method - (CAM-S long form)
Timeframe: The CAM-S long form will be recorded every 12 hours during the four-week experimental period and also every 12 hours during the four-week control period.
2
Unit noise levels (Decibels)
Timeframe: 10 seconds Decibel measurement periods will be recorded consecutively for two four-week periods, consisting of the four-week intervention period, and the four-week control period.
3
Alarm Fatigue
Timeframe: The staff response times will be measured (in seconds) for every alarm occurring during the four-week intervention and control periods.
