Calm Critical Care—filtered noise reduction solutions for Critical Care Units (CCU)

How can a hospital distribute alerts from monitors and other bedside equipment  to mobile CCU staff, while simultaneously minimizing noise pollution and the risk of ‘alarm fatigue’? The challenge is that staff require timely patient data and alerts. But too many clinically insignificant alerts—particularly at night—impact staff, and can compromise patient well-being. One possible way forward is intelligent alert notification management that filters the flow of alerts to frontline staff.

771. That’s the average number of alarm conditions a single CCU bed at Johns Hopkins Hospital in the US bed generated in one day.1 It’s a figure that highlights a major challenge: CCUs are becoming increasingly noisy. And it’s not only staff and workflows that suffer. Excessive noise from clinically insignificant alarms disturbs patients, leading to sleep deprivation, delirium and increased consumption of medications.2 Ascom CCU solutions can improve the situation by intelligently filtering alerts, ensuring they go to the right person at the right time.

  • How Ascom can help reduce noise pollution and alert fatigue at Critical Care Units

    Each Calm Critical Care solution is unique; tailored to a hospital’s specific needs and resources. But a solution typically incorporates an Ascom nurse call system, Ascom Unite and Digistat softwares and applications, and Ascom handsets. Bedside equipment such as monitors and pumps can be connected to the nurse call system via an Ascom Multiple Medical Alarm Module.* Monitoring equipment can also be connected centrally by using network connections to the Ascom Unite and Digistat softwares.

    Ascom Unite and Digistat softwares are the intelligent cores of a Calm Critical Care solution. In addition to processing alerts from medical devices, Ascom softwares also direct these alerts along wireless infrastructure (typically Wi-Fi or DECT) to individual caregivers’ handsets such as the built-for-Healthcare Ascom Myco smartphone.  

    * The Ascom Multiple Medical Alarm Module is available only in the EU.

    Why is noise reduction important?

    • Number of alarms generated per patient

      Average daily number for one ICU patient [1] 771
      771
    • Number of 'unnecessary' PM alarms

      Non-clinically significant patient monitoring alarms [2] 80-99%
      80-99%
    • Daytime average for ambient noise

      Noise has been linked to sleep deprivation.[3],[4],[5] 72dB
      72dB
