Attempts to optimize monitoring of brace adherence prescribed to adolescents with idiopathic scoliosis (IS) have generally relied on sensors. Sensors, however, are intrusive and do not allow the assessment of psychological and physical consequences of brace use that might underlie poor adherence. Mobile applications have emerged as alternatives to monitor brace compliance. However, the feasibility and utility of these app-based systems to assess key psychological and physical domains associated with non-adherence remain unexplored. This feasibility study aims to test the usability, acceptability, and clinical utility of an app-based system that monitors brace use and related psychological and physical factors. Forty adolescents with IS daily respond to the app for 90 days. The patient responses may generate clinical alarms (e.g., brace non-adherence, discomfort, or distress) that will be sent daily to the medical team. Primary outcomes will be app usability, acceptability, and response rates. Secondary outcomes will include brace adherence, the number of side effects reported, number and type of clinical alarms, stress, quality of life, perceived health status, and mood. If accepted by patients and clinicians, apps may allow rapid detection and response to undesired events in adolescents undergoing brace treatment.

Although there has been much attention paid recently to clinical alarms, research has primarily focused on particular aspects of the clinical alarm problem, such as how to reduce nuisance alarms. This paper takes a broad view of clinical alarms and develops a model of errors in alarm handling and how they affect patients directly. Based on reports in the literature, I estimate that alarms that should sound by current standards do not sound about 9% of the time. Additionally, about 3% of alarms that are clinically significant are ignored, either intentionally or because they were inaudible. However, these errors produce a very low rate of reported alarmrelated deaths and other adverse effects (on the order of a couple adverse effects per 10 million alarm errors). While it is not yet possible to estimate the probabilities of clinical alarms having an adverse impact on patients other than the patient whose alarm is sounding, such indirect adverse effects likely occur at a low level as a result of disruption of staff workflow, creation of a noisy hospital environment, and contribution to communication difficulties. Consideration of alarms should include not only the patient connected to the device that is sounding, but also the impact of the alarm on other patients in the vicinity.

Almost all medical devices in ICU/CCU have a built-in clinical alarm system to alert when there are changes in a patient’s condition. The objective of this study is to investigate the effectiveness of the existing alarm system in ICU/CCU. Two summative usability tests were conducted to test the effectiveness of existing and new alarm signals based on IEC 60601-1-8:2006 standard. Further formative test is conducted to study the perception of urgency associated with a number of tones in the alarm signals. The findings indicate that the existing auditory alarm signal in ICU/CCU does not indicate the urgency of the alarm conditions. The simulation test indicates that the respondents preferred 282Hz, 500Hz and 800Hz for low, medium and high-risk alarm respectively. The one-sample proportion z test on urgency mapping indicates that the proportion of responses for the highest risk is more than 50% for a single tone test signal. These results show that a single tone test signal being perceived as the highest risk is regardless of frequency. It can be concluded the auditory alarm designed based on this IEC 60608-1-8:2006 standard is not effective. As such it is proposed that the incorporation of the new alarm frequencies and tones will improve the effectiveness of the alarm signal
