Develop algorithms to determine the status of car drivers using built-in accelerometer and GBDT

<span>In this paper, we introduce a mobile application called CarSafe, in which data from the acceleration sensor integrated on smartphones is exploited to come up with an efficient classification algorithm. Two statuses, "Driving" or "Not driving," are monitored in the real-time manner. It enables automatic actions to help the driver safer. Also, from these data, our software can detect the crash situation. The software will then automatically send messages with the user's location to their emergency departments for timely assistance. The application will also issue the same alert if it detects a driver of a vehicle driving too long. The algorithm's quality is assessed through an average accuracy of 96.5%, which is better than the previous work (i.e., 93%).</span>

Length of stay as quality indicator in emergency departments: analysis of determinants in the German Emergency Department Data Registry (AKTIN registry)

Several indicators reflect the quality of care within emergency departments (ED). The length of stay (LOS) of emergency patients represents one of the most important performance measures. Determinants of LOS have not yet been evaluated in large cohorts in Germany. This study analyzed the fixed and influenceable determinants of LOS by evaluating data from the German Emergency Department Data Registry (AKTIN registry). We performed a retrospective evaluation of all adult (age ≥ 18 years) ED patients enrolled in the AKTIN registry for the year 2019. Primary outcome was LOS for the whole cohort; secondary outcomes included LOS stratified by (1) patient-related, (2) organizational-related and (3) structure-related factors. Overall, 304,606 patients from 12 EDs were included. Average LOS for all patients was 3 h 28 min (95% CI 3 h 27 min–3 h 29 min). Regardless of other variables, patients admitted to hospital stayed 64 min longer than non-admitted patients. LOS increased with patients’ age, was shorter for walk-in patients compared to medical referral, and longer for non-trauma presenting complaints. Relevant differences were also found for acuity level, day of the week, and emergency care levels. We identified different factors influencing the duration of LOS in the ED. Total LOS was dependent on patient-related factors (age), disease-related factors (presentation complaint and triage level), and organizational factors (weekday and admitted/non-admitted status). These findings are important for the development of management strategies to optimize patient flow through the ED and thus to prevent overcrowding.

Rapid response pathway united to reduce self-harm (RUSH): a case study of a pilot pathway for children and young people

Purpose In response to elevated local self-harm and suicide rates, and the lack of a dedicated pathway for children and young people (CYP) who self-harm, a rapid response pathway united to reduce self-harm (RUSH) was developed and implemented within Norwich (Norfolk, England). This public health case study aims to describe the pathway model and share its outcomes, learnings, and reflections over the pilot year. Design/methodology/approach RUSH was a community-based pilot pathway aiming to support CYP, 11–18 years old, engaging in or at risk of engaging in repeated self-harm and subsequently at risk of repeated attendance at local emergency departments. From May 2020 to April 2021, RUSH supported 61 CYP using funding from NHS England and Improvement. Findings This case study shares the pathway’s outcomes, through a mixed-method evaluation. Results indicate statistically significant reductions in self-harm frequency (p = 0.01) and anxiety and depression symptomatology (p < 0.001); a statistically significant increase in progress towards goals (p < 0.001); and a general downward trend in re-attendance at local emergency departments following RUSH. Findings also illustrate high service user satisfaction. Framework analysis of focus group data highlights positive experiences with hope for recommissioning from a staff perspective. Originality/value This study will be valuable for services looking to develop and implement a similar service provision, in response to the need to tackle self-harm rates as a broader approach to suicide prevention. In light of the NHS long-term plan (2019), it also serves as an example of how to develop and use a strategic co-production group, and work collaboratively with the voluntary, community and social enterprise sectors.
