Tailored Basic Life Support Training for Specific Layperson Populations-A Scoping Review.

Background: Basic life support (BLS) is a life-saving link in the out-of-hospital cardiac arrest chain of survival. Most members of the public are capable of providing BLS but are more likely to do so confidently and effectively if they undertake BLS training. Lay members of the public comprise diverse and specific populations and may benefit from tailored BLS training. Data on this topic are scarce, and it is completely unknown if there are any benefits arising from tailored courses or for whom course adaptations should be developed. Methods: The primary objective of this scoping review was to identify and describe differences in patient, clinical, and educational outcomes when comparing tailored versus standard BLS courses for specific layperson populations. This review was undertaken as part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation. Results: A primary search identified 1307 studies and after title, abstract, and full-text screening, we included eight publications reporting on tailored courses for specific populations. There were no studies reporting direct comparisons between tailored and standardized training. Seven (88%) studies investigated courses tailored for individuals with a disability, and only one study covered another specific population group (refugees). Overall, the quality of evidence was low as the studies did not compare tailored vs. non-tailored approaches or consisted of observational or pre-post-designed investigations. Conclusions: Tailored BLS education for specific populations is likely feasible and can include such groups into the pool of potential bystander resuscitation providers. Research into comparing tailored vs. standard courses, their cost-to-benefit ratio, how to best adapt courses, and how to involve members of the respective communities should be conducted. Additionally, tailored courses for first responders with and without a duty to respond could be explored

International facets of the 'chain of survival' for out-of-hospital and in-hospital cardiac arrest - A scoping review.

BACKGROUND The "chain of survival" was first systematically addressed in 1991, and its sequence still forms the cornerstone of current resuscitation guidelines. The term "chain of survival" is widely used around the world in literature, education, and awareness campaigns, but growing heterogeneity in the components of the chain has led to confusion. It is unclear which of these emerging chains is most suitable, or if adaptations are needed in particular contexts to depict key actions of resuscitation in the 21st century. This scoping review provides an overview of the variety of chains of survival described. OBJECTIVES To identify published facets of the chain of survival, to assess views and strategies about adapting the chain, and to identify reports on how the chain of survival affects teaching, implementation, or patient outcomes. METHODS ELIGIBILITY CRITERIA AND SOURCES OF EVIDENCE A scoping review as part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation (ILCOR) was conducted. MEDLINE(R) ALL (Ovid), Embase (Ovid), APA PsycINFO (Ovid), CINAHL (Ebscohost), ERIC (Ebscohost), Web of Science (Clarivate), Scopus (Elsevier), and Cochrane Library (Wiley Online) were searched. All publications in all languages describing chains of survival were eligible, without time restrictions. Due to the heterogeneity and publication types of the relevant studies, we did not pursue a systematic review or meta-analysis. RESULTS A primary search yielded 1713 studies and after screening we included 43 publications. Modified versions of the chain of survival for specific contexts were found (e.g., in-hospital cardiac arrest or paediatric resuscitation). There were also numerous versions with minor adaptations of the existing chain. Three publications suggested an impact of the use of the chain of survival on patient outcomes. No educational or implementation outcomes were reported. CONCLUSION There is a vast heterogeneity of chain of survival concepts published. Future research is warranted, especially into the concept's importance concerning educational, implementation, and clinical outcomes

AsTeRICS, a Flexible Assistive Technology Construction Set

AbstractOver the last decades a considerable number of information and communication technology based Assistive Technology devices have become available for people with disabilities. These Assistive Technology devices often ask for adaptation of software and/or hardware to fit the users abilities before they can be used.Within the Project AsTeRICS, a flexible and affordable construction set for the implementation of user driven assistive technologies solutions will be developed. This allows the combination of different sensors to process and manipulate the sensor data to control any supported device. This paper will show how a webcam mouse (head tracker) and a single switch mouse can easily be created and tailored to the user needs and possibilities. Additionally, results of user tests with the head tracker will be presented

Out of sight – Out of mind? The need for a professional and standardized peri-mission first responder support model

First responders are an essential part of the chain (-mail) of survival as they bridge and reduce the time to first chest compressions and defibrillation substantially. However, in the peri-mission phase before and after being sent to a cardiac arrest, these first responders are in danger of being forgotten and taken for granted, and the potential psychological impact has to be remembered. We propose a standardized first responder support system (FRSS) that needs to ensure that first responders are valued and cared for in terms of psychological safety and continuing motivation. This multi-tiered program should involve tailored education and standardized debriefing, as well as actively seeking contact with the first responders after their missions to facilitate potentially needed professional psychological support

The Impact of Chronic Oral Beta-Blocker Intake on Intravenous Bolus Landiolol Response in Hospitalized Intensive Care Patients with Sudden-Onset Supraventricular Tachycardia—A Post Hoc Analysis of a Cross-Sectional Trial

Background: Landiolol, a highly cardioselective agent with a short half-life (2.4–4 min), is commonly used as a perfusor or bolus application to treat tachycardic arrhythmia. Some small studies suggest that prior oral β-blocker use results in a less effective response to intravenous β-blockers. Methods: This study investigated whether prior chronic oral β-blocker (Lβ) or no prior chronic oral β-blocker (L–) intake influences the response to intravenous push-dose Landiolol in intensive care patients with acute tachycardic arrhythmia. Results: The effects in 30 patients (67 [55–72] years) were analyzed, 10 (33.3%) with and 20 (66.7%) without prior oral β-blocker therapy. Arrhythmias were diagnosed as tachycardic atrial fibrillation in 14 patients and regular, non-fluid-dependent, supraventricular tachycardia in 16 cases. Successful heart rate control (Lβ 4 vs. L– 7, p = 1.00) and rhythm control (Lβ 3 vs. L– 6, p = 1.00) did not significantly differ between the two groups. Both groups showed a significant decrease in heart rate when comparing before and after the bolus administration, without significant differences between the two groups (Lβ −26/min vs. L– −33/min, p = 0.528). Oral β-blocker therapy also did not influence the change in mean arterial blood pressure after Landiolol bolus administration (Lβ −5 mmHg vs. L– −4 mmHg, p = 0.761). Conclusions: A prior chronic intake of β-blockers neither affected the effectiveness of push-dose Landiolol in heart rate or rhythm control nor impacted the difference in heart rate or mean arterial blood pressure before and after the Landiolol boli

Hemodynamic and Rhythmologic Effects of Push-Dose Landiolol in Critical Care—A Retrospective Cross-Sectional Study

Background: The highly β1-selective beta-blocker Landiolol is known to facilitate efficient and safe rate control in non-compensatory tachycardia or dysrhythmia when administered continuously. However, efficacy and safety data of the also-available bolus formulation in critically ill patients are scarce. Methods: We conducted a retrospective cross-sectional study on a real-life cohort of critical care patients, who had been treated with push-dose Landiolol due to sudden-onset non-compensatory supraventricular tachycardia. Continuous hemodynamic data had been acquired via invasive blood pressure monitoring. Results: Thirty patients and 49 bolus applications were analyzed. Successful heart rate control was accomplished in 20 (41%) cases, rhythm control was achieved in 13 (27%) episodes, and 16 (33%) applications showed no effect. Overall, the heart rate was significantly lower (145 (130–150) vs. 105 (100–125) bpm, p < 0.001) in a 90 min post-application observational period in all subgroups. The median changes in blood pressure after the bolus application did not reach clinical significance. Compared with the ventilation settings before the bolus application, the respiratory settings including the required FiO2 after the bolus application did not differ significantly. No serious adverse events were seen. Conclusions: Push-dose Landiolol was safe and effective in critically ill ICU patients. No clinically relevant impact on blood pressure was noted
