    Abstract: In high-risk industries, responding accurately and promptly to spoken commands is crucial to ensure safety and productivity. When simultaneous sounds occur, it increases the difficulty of responding efficiently and accurately. This study examined responses to spoken commands in an audio-visual multitasking paradigm that simulated a high-consequence working environment. Participants had varying levels of formal music training (FMT): no FMT, 1–3, 3–5, and 5+ years of FMT. We found that FMT groups were similar in accuracy overall and background music decreased accuracy for all groups. The degree of FMT significantly impacted non-response. Additionally, there was an interaction where the no FMT group responded 1.5-fold less frequently in the presence of background music; however, participants with 5+ years of FMT had no decrease. Considering the similar accuracy with less frequent responding, the 5+ years FMT group appears well calibrated to when they were unsure of the answer, suggestive of improved meta-cognition which could be valuable in high-risk industry settings. Future research can examine performance within different types or quality of musical training, and pedagogical approaches can be compared.

    Abstract: In high-risk domains, accurate and timely communications while multitasking are necessary for safety and efficiency. Complex musical/acoustic environments cause hindered communication and awareness. This study used an audio-visual multi-tasking paradigm that examined speech intelligibility and if formal music training (FMT) can mitigate these challenges. Twenty-five students (16F/9M) from Vanderbilt University participated with varying levels of FMT: no FMT, 1–3 years, 3–5 years, and 5+ years of FMT. The study found that the degree of FMT significantly impacted non-response (p-value  & lt; 0.001). Among participants with no FMT, the presence of background music increased the odds of non-response by 1.5-fold (95% CI: 0.95, 2.37), conversely, participants with 5+ years of FMT had no decrease (OR: 0.97, 95% CI: 0.69, 1.36), showing that non-response in the presence of music worsens with each subgroup until 5+ years of FMT. The accuracy for all groups was similar (p = 0.74) and the background music decreased accuracy for all groups (OR: 0.67, 95% CI: 0.58, 0.76). Although levels of accuracy were similar for all, the 5+ FMT group responded less frequently, which may indicate increased working memory (i.e., phonological loop) and meta-cognition, a valuable skill in high-risk industry. Future research can explore the pedagogy of musical training.

    Abstract: Audible alarms are a ubiquitous feature of all high-paced, high-risk domains such as aviation and nuclear power where operators control complex systems. In such settings, a missed alarm can have disastrous consequences. It is conventional wisdom that for alarms to be heard, “louder is better,” so that alarm levels in operational environments routinely exceed ambient noise levels. Through a robust experimental paradigm in an anechoic environment to study human response to audible alerting stimuli in a cognitively demanding setting, akin to high-tempo and high-risk domains, clinician participants responded to patient crises while concurrently completing an auditory speech intelligibility and visual vigilance distracting task as the level of alarms were varied as a signal-to-noise ratio above and below hospital background noise. There was little difference in performance on the primary task when the alarm sound was −11 dB below background noise as compared with +4 dB above background noise—a typical real-world situation. Concurrent presentation of the secondary auditory speech intelligibility task significantly degraded performance. Operator performance can be maintained with alarms that are softer than background noise. These findings have widespread implications for the design and implementation of alarms across all high-consequence settings.

    Masking Between Reserved Alarm Sounds of the IEC 60601-1-8 International Medical Alarm Standard: A Systematic, Formal Analysis
    SAGE Publications ; 2022

    Abstract: In this work, we systematically evaluated the reserved alarm sounds of the IEC 60601-1-8 international medical alarm standard to determine when and how they can be totally and partially masked. Background IEC 60601-1-8 gives engineers instruction for creating human-perceivable auditory medical alarms. This includes reserved alarm sounds: common types of alarms where each is a tonal melody. Even when this standard is honored, practitioners still fail to hear alarms, causing practitioner nonresponse and, thus, potential patient harm. Simultaneous masking, a condition where one or more alarms is imperceptible in the presence of other concurrently sounding alarms due to limitations of the human sensory system, is partially responsible for this. Methods In this research, we use automated proof techniques to determine if masking can occur in a modeled configuration of medical alarms. This allows us to determine when and how reserved alarm sound can mask other reserved alarms and to explore parameters to address discovered problems. Results We report the minimum number of other alarm sounds it takes to both totally and partially mask each of the high-, medium-, and low-priority alarm sounds from the standard. Conclusions Significant masking problems were found for both the total and partial masking of high-, medium-, and low-priority reserved alarm sounds. Application We show that discovered problems can be mitigated by setting alarm volumes to standard values based on priority level and by randomizing the timing of alarm tones.

    Abstract: The reserved set of audible alarm signals embodied within the global medical device safety standard, IEC 60601-1-8, is known to be problematic and in need of updating. The current alarm signals are not only suboptimal, but there is also little evidence beyond learnability (which is known to be poor) that demonstrates their performance in realistic and representative clinical environments. In this article, we describe the process of first designing and then testing potential replacement audible alarm signals for IEC 60601-1-8, starting with the design of several sets of candidate sounds and initial tests on learnability and localizability, followed by testing in simulated clinical environments. We demonstrate that in all tests, the alarm signals selected for further development significantly outperform the current alarm signals. We describe the process of collecting considerably more data on the performance of the new sounds than exists for the current sounds, which ultimately will be of use to end users. We also reflect on the process and practice of working with the relevant committees and other practical issues beyond the science, which also need constant attention if the alarms we have developed are to be included successfully in an updated version of the standard.

    Abstract: Non-technical skills (NTS) have gained increasing recognition in recent years for their role in safe, effective team performance in healthcare. Gastrointestinal endoscopy is a procedure-based specialty with rapidly advancing technology, significant operational pressures and rapidly changing ‘teams of experts’. However, to date there has been little focus on the effect of NTS in this field. Objectives This review aims to examine the existing literature on NTS in gastrointestinal endoscopy and identify areas for further research. Method A systematic search of MEDLINE, Embase, Cochrane Library, PsychINFO, CINAHL Plus and PubMed databases was performed using search terms Non-Technical Skills, Team Performance or Team Skills, and Endoscopy, Colonoscopy, OGD, Gastroscopy, Endoscopic Retrograde Cholangio-Pancreatography or Endoscopic Ultrasound. Results Eighteen relevant publications were found. NTS are deemed an essential component of practice, but so far there is little evidence of their integration into training or competency assessment. Those studies examining the effects of NTS and team training in endoscopy are small and have variable outcome measures with limited evidence of improvement in skills or clinical outcomes. NTS assessment in endoscopy is in its early phases with a few tools in development. Conclusions The current literature on NTS in gastrointestinal endoscopy is limited. NTS, however, are deemed an essential component of practice, with potential positive effects on team performance and clinical outcomes. A validated reliable tool would enable evaluation of training and investigation into the effects of NTS on outcomes. There is a clear need for further research in this field.

    Abstract: Current standard audible medical alarms are difficult to learn and distinguish from one another. Auditory icons represent a new type of alarm that has been shown to be easier to learn and identify in laboratory settings by lay subjects. In this study, we test the hypothesis that icon alarms are easier to learn and identify than standard alarms by anesthesia providers in a simulated clinical setting. Methods Twenty anesthesia providers were assigned to standard or icon groups. Experiments were conducted in a simulated intensive care unit. After a brief group-specific alarm orientation, subjects identified patient-associated alarm sounds during the simulation and logged responses via a tablet computer. Each subject participated in the simulation twice and was exposed to 32 alarm annunciations. Primary outcome measures were response accuracy and response times. Secondary outcomes included assessments of perceived fatigue and task load. Results Overall accuracy rate in the standard alarm group was 43% (mean) and in the icon group was 88% (mean). Subjects in the icon group were 26.1 (odds ratio [98.75% CI, 8.4 to 81.5; P & lt; 0.001]) times more likely to correctly identify an alarm. Response times in the icon group were shorter than in the standard alarm group (12 vs. 15 s, difference 3 s [98.75% CI ,1 to 5; P & lt; 0.001]). Conclusions Under our simulated conditions, anesthesia providers more correctly and quickly identified icon alarms than standard alarms. Subjects were more likely to perceive higher fatigue and task load when using current standard alarms than icon alarms.
