“…Most of these papers are from Cobus et al since their proposed method includes hardware. These user studies consisted of the testing of the prototype ( 47 , 73 , 76 , 77 ), performance of tasks ( 46 , 47 , 77 ), interviews ( 45 , 58 ), as well as pilot sessions ( 42 ). Not all the papers included the number or the background of the participants in their user study.…”

“…The modalities used are vibration, peripheral light and (bone conduction) sound. They present a vibrotactile wearable alarm system worn on the upper arm ( 47 ) as well as different versions of a head-mounted display for alarm presentation showing an evolution throughout the years 2017 to 2019 ( 45 , 46 , 76 , 77 ). The head-mounted display delivers alarms as well as alarm-relevant information, such as the patient’s vital data, the sensor, the respective patient’s name or its priority.…”

Patient monitoring technology has been used to guide therapy and alert staff when a vital sign leaves a predefined range in the intensive care unit (ICU) for decades. However, large amounts of technically false or clinically irrelevant alarms provoke alarm fatigue in staff leading to desensitisation towards critical alarms. With this systematic review, we are following the Preferred Reporting Items for Systematic Reviews (PRISMA) checklist in order to summarise scientific efforts that aimed to develop IT systems to reduce alarm fatigue in ICUs. 69 peer-reviewed publications were included. The majority of publications targeted the avoidance of technically false alarms, while the remainder focused on prediction of patient deterioration or alarm presentation. The investigated alarm types were mostly associated with heart rate or arrhythmia, followed by arterial blood pressure, oxygen saturation, and respiratory rate. Most publications focused on the development of software solutions, some on wearables, smartphones, or headmounted displays for delivering alarms to staff. The most commonly used statistical models were tree-based. In conclusion, we found strong evidence that alarm fatigue can be alleviated by IT-based solutions. However, future efforts should focus more on the avoidance of clinically non-actionable alarms which could be accelerated by improving the data availability.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021233461, identifier: CRD42021233461.

“…Finally, Cobus and colleagues have examined how alarm information can be effectively distributed across clinicians and locations within an intensive care unit, again exploring wearable alarm solutions including the use of multimodality. After initially gathering requirements with clinicians in the field Cobus and Heuten (2019) and Cobus et al (2018, 2019) tested eight different ways of conveying three urgency levels, unrelated to any particular vital signs. They found that patterns that increased the repetition rate or tacton duration were interpreted as more urgent.…”

“…In Section 4, we describe our requirements for a multimodal wearable alarm system (WAS), based on a requirements analysis published in 2018 [9]. Sections 5 and 6 are based on previous publications [10,11], which motivated and documented the design of vibrotactile and peripheral light alarm patterns and their general applicability in this context. The results from these earlier studies suggested the patterns we used in the final evaluation.…”

Technology plays a prominent role in intensive care units (ICU), with a variety of sensors monitoring both patients and devices. A serious problem exists, however, that can reduce the sensors’ effectiveness. When important values exceed or fall below a certain threshold or sensors lose their signal, up to 350 alarms per patient a day are issued. These frequent alarms are audible in several locations on the ICU, resulting in a massive cognitive load for ICU nurses, as they must evaluate and acknowledge each alarm. “Alarm fatigue” sets in, a desensitization and delayed response time for alarms that can have severe consequences for patients and nurses. To counteract the acoustic load on ICUs, we designed and evaluated personal multimodal alarms for a wearable alarm system (WAS). The result was a lower response time and higher ratings on suitability and feasibility, as well as a lower annoyance level, compared to acoustic alarms. We find that multimodal alarms are a promising new approach to alert ICU nurses, reduce cognitive load, and avoid alarm fatigue.
