Anticipatory manual defibrillator charging during advanced life support: A scoping review.
Ontology highlight
ABSTRACT: Background
Some resuscitation services advocate or teach routine manual defibrillator charging prior to a rhythm check during cardiopulmonary resuscitation.Objectives
We aimed to review the evidence for anticipatory defibrillator charging compared with charging after a shockable rhythm is confirmed.Methods
This scoping review was performed according to a specific methodological framework and the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. Grey literature was also reviewed using similar methodology and included in the results.Results
There are no randomized clinical trials studying anticipatory manual defibrillator charging. The limited available data does not address critical or important patient outcomes such as defibrillation success, return of spontaneous circulation, survival to hospital discharge or neurological outcomes. Evidence primarily from manikin studies and the grey literature suggests that anticipatory charging is feasible, safe, and can reduce the total pause duration during the period of chest compression between rhythm checks, but can increase the pre-shock pause and total peri-shock pause duration.Conclusions
Anticipatory manual defibrillator charging appears to be feasible in the clinical setting, although its impact on clinical outcomes is uncertain. Future studies of anticipatory charging should focus on clinical outcomes.

Project description:The aim of this scoping review initiated by the Education, Implementation and Teams Task Force of the International Liaison Committee on Resuscitation was to identify faculty development approaches to improve instructional competence in accredited life support courses. We searched PubMed, Ovid Embase, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Central Register of Controlled Trials to identify studies published from January 1, 1966 to December 31, 2021 on approaches to improve faculty development for life support courses. Data on participant characteristics, interventions, design, and outcomes of included studies were extracted. Of the initially identified 10 310 studies, we included 20 studies (5 conference abstracts, 1 short communication, 14 full-length articles). Among them, 12 studies aimed to improve instructors/candidates' teaching ability in basic life support courses. A wide variety of interventions were identified. The interventions were categorized into 4 themes: instructor qualification/training (n=9), assessment tools (n=3), teaching skills enhancement (n=3), and additional courses for instructors (n=5). Most studies showed that these interventions improved specific teaching ability or confidence of the instructors and learning outcomes in different kinds of life support courses. However, no studies addressed clinical outcomes of patients. In conclusion, the faculty development approaches for instructors are generally associated with improved learning outcomes for participants, and also improved teaching ability and self-confidence of the instructors. It is encouraged that local organizations implement faculty development programs for their teaching staff of their accredited resuscitation courses. Further studies should explore the best ways to strengthen and maintain instructor competency, and define the cost-effectiveness of various different faculty development strategies.

Project description:Early intervention of bystanders (the first links of the chain of survival) have been shown to improve survival and good neurological outcomes of patients suffering out-of-hospital cardiac arrest (OHCA). Many initiatives have been implemented to increase the engagement of communities in early basic life support (BLS) and cardiopulmonary resuscitation (CPR), especially of lay people with no duty to respond. A better knowledge of the most effective initiatives might help improve survival and health system organization. Aim of the scoping review: To assess the impact of specific interventions involving lay communities on bystander BLS rates and other consistent clinical outcomes, and to identify relevant knowledge gaps. This scoping review was part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation (ILCOR), and was performed following the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. We performed a literature search using the PubMed, EMBASE, and Cochrane databases until 1 February 2021. The screening process was conducted based on predefined inclusion/exclusion criteria, and for each included study, we performed data extraction focusing on the type of intervention implemented, and the impact of these interventions on the specific OHCAs outcomes. Our search strategy identified 19 eligible studies, originating mainly from the USA (47.4%) and Denmark (21%). The type of intervention included in 57.9% of cases was a community CPR training program, in 36.8% bundled interventions, and in 5.3% mass-media campaigns. The most commonly reported outcome for OHCAs was bystander CPR rate (94.7%), followed by survival to hospital discharge (36.8%), proportion of people trained (31.6%), survival to hospital discharge with good neurological outcome (21%), and Return of Spontaneous Circulation (10.5%). Community training programs and bundled interventions improved bystander CPR in most of the included studies. Based on the results of our scoping review, we identified the potential benefit of community initiatives, such as community training in BLS, even as part of bundled intervention, in order to improve bystander CPR rates and patient outcomes.

Project description:BackgroundAlthough patient portals are widely used for health promotion, little is known about the use of palliative care and end-of-life (PCEOL) portal tools available for patients and caregivers.ObjectiveThis study aims to identify and assess the user perspectives of PCEOL portal tools available to patients and caregivers described and evaluated in the literature.MethodsWe performed a scoping review of the academic literature directed by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) extension for Scoping Review and searched three databases. Sources were included if they reported the development or testing of a feature, resource, tool, or intervention; focused on at least one PCEOL domain defined by the National Coalition for Hospice and Palliative Care; targeted adults with serious illness or caregivers; and were offered via a patient portal tethered to an electronic medical record. We independently screened the titles and abstracts (n=796) for eligibility. Full-text (84/796, 10.6%) sources were reviewed. We abstracted descriptions of the portal tool name, content, targeted population, and reported user acceptability for each tool from included sources (n=19).ResultsIn total, 19 articles describing 12 tools were included, addressing the following PCEOL domains: ethical or legal (n=5), physical (n=5), and psychological or psychiatric (n=2). No tools for bereavement or hospice care were identified. Studies have reported high acceptability of tools among users; however, few sources commented on usability among older adults.ConclusionsPCEOL patient portal tools are understudied. As medical care increasingly moves toward virtual platforms, future research should investigate the usability and acceptability of PCEOL patient portal resources and evaluate their impact on health outcomes.

Project description:The American Heart Association (AHA) advocates for CPR education as a requirement of secondary school curriculum. Unfortunately, many states have not adopted CPR education. Our aim was to investigate a low-cost, time effective method to educate students on Basic Life Support (BLS), including reeducation. This is a prospective, randomized study. Retention was assessed at 4 months post-initial education. Education was performed by AHA-certified providers during a 45-minute physical education class in a middle school in Florida. This age provides opportunities for reinforcement through high school, with ability for efficient learning. The study included 41 Eighth grade students. Students were randomized into two groups; one group received repeat education 2 months after the first education, the second group did not. All students received BLS education limited to chest compressions and usage of an Automated External Defibrillator. Students had skills and knowledge tests administered pre- and post-education after initial education, and repeated 2 and 4 months later to assess retention. There was a significant increase in CPR skills and knowledge when comparing pre- and post-education results for all time-points (p < 0.001). When assessing reeducation, a significant improvement was noted in total knowledge scores but not during the actual steps of CPR. Our study indicates significant increase in CPR knowledge and skills following a one-time 45-minute session. Reeducation may be useful, but the interval needs further investigation. If schools across the United States invested one 45-60-minute period every school year, this would ensure widespread CPR knowledge with minimal cost and loss of school time.

Project description:ObjectivesTo review the use of manual therapies (MT) for pain, respiratory muscle strength and pulmonary function in cystic fibrosis (CF) care.MethodsA search with a systematic approach was conducted by two independent reviewers, using the databases Medline, PubMed, Scopus and Cinahl from their respective inception dates to March 2021.ResultsA total of 199 publications were initially screened by title and abstract, after which 190 were excluded. Following a full-text review of the remaining articles, six studies with a total of 234 participants were included. Decreased pain levels following MT were observed in two studies and, in three studies, patient reports on improvement in ease of breathing and peak airflow were presented. No significant effects on spirometry measures were observed and none of the included studies investigated respiratory muscle strength.ConclusionCurrent research on MT in CF care indicates positive trends based on subjective measures. However, research in this context is sparse and disparate in terms of both interventions and methodology. Further investigations including MT as part of multimodal interventions are therefore suggested before any specific recommendations for clinical implementation of MT in CF can be provided.

Project description:In recent years, studies have increasingly employed data logger technologies to record objective driving and physiological characteristics of manual wheelchair users. However, the technologies used offer significant differences in characteristics, such as measured outcomes, ease of use, and level of burden. In order to identify and describe the extent of published research activity that relies on data logger technologies for manual wheelchair users, we performed a scoping review of the scientific and gray literature. Five databases were searched: Medline, Compendex, CINAHL, EMBASE, and Google Scholar. The 119 retained papers document a wide variety of logging devices and sensing technologies measuring a range of outcomes. The most commonly used technologies were accelerometers installed on the user (18.8%), odometers installed on the wheelchair (12.4%), accelerometers installed on the wheelchair (9.7%), and heart monitors (9.7%). Not surprisingly, the most reported outcomes were distance, mobility events, heart rate, speed/velocity, acceleration, and driving time. With decreasing costs and technological improvements, data loggers are likely to have future widespread clinical (and even personal) use. Future research may be needed to assess the usefulness of different outcomes and to develop methods more appropriate to wheelchair users in order to optimize the practicality of wheelchair data loggers.

Project description:ePortfolios are frequently used to support students' competency development, and teachers' and clinical mentors' supervision during clinical placements. User training is considered a critical success factor for the implementation of these ePortfolios. However, there is ambiguity about the design and outcomes of ePortfolio user training. A scoping review was conducted to consolidate evidence from studies describing the design of ePortfolio user training initiatives and their outcomes. The search yielded 1180 articles of which 16 were included in this review. Based on the results, an individual, ongoing training approach which grounds in a fitting theoretical framework is recommended.Supplementary informationThe online version contains supplementary material available at 10.1007/s40670-022-01583-0.

Project description:AimTo conduct an overview of systematic reviews and meta-analyses to summarize the ever-growing evidence on drug use during advanced life support.MethodsWe searched Embase, Medline, Cochrane central register of controlled trials and Web of science for systematic reviews and meta-analyses reporting on drug use during advanced life support from inception to March, 2020. Two reviewers independently assessed all abstracts for eligibility, extracted data and assessed risk of bias using the AMSTAR-2 tool. Corrected covered areas were calculated from publication citation matrices to account for potential risk of bias. Data were graphically represented using forest plots.ResultsTwenty-two head-to-head drug comparisons from 47 included articles were analysed. Adrenaline significantly increases the incidence of return of spontaneous circulation and survival to hospital discharge, but not the incidence of neurological intact survival. Vasopressin alone or in combination with adrenaline is not superior to adrenaline alone. There is a trend favouring lidocaine over amiodarone in shockable cardiac arrest. The risk of bias assessment of included studies ranged from very low to very high and the overlap between articles was moderate to high.ConclusionsIn line with the guidelines, we currently suggest that a standard dose of adrenaline should be administered during resuscitation, however, studies assessing lower doses of adrenaline are pressing. There is no rationale for the combination of vasopressin and adrenaline or vasopressin alone instead of adrenaline. In addition, lidocaine is a valuable alternative for amiodarone and maybe even preferable for shockable cardiac arrest. However more research is necessary.

Project description:Background: Advanced Life Support (ALS) is regarded to be associated with improved survival in pre-hospital trauma care when compared to Basic Life Support (BLS) irrespective of lack of evidence. The aim of this study is to ascertain ALS improves survival for trauma in prehospital settings when compared to BLS. Methods: We searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials for published controlled trials (CTs), and observational studies that were published until Aug 2017. The population of interest were adults (>18 years old) trauma patients who were transported by ground transportation and required resuscitation in prehospital settings. We compared outcomes between the ALS and BLS groups. The primary outcome was in-hospital mortality and secondary outcomes were neurological outcome and time spent on scene. Results: We identified 2,502 studies from various databases and 10 studies were included in the analysis (two CTs, and eight observational studies). The outcomes were not statistically significant between the ALS and BLS groups (pooled OR 1.14; 95% CI 0.95 to 1.36 for mortality, pooled OR 1.12; 95% CI 0.88 to 1.42 for good neurological outcomes, pooled mean difference -0.96; 95% CI-6.64 to 4.72 for on-scene time) in CTs. In observational studies, ALS prolonged on-scene time and increased mortality (pooled OR 1.56; 95% CI: 1.31 to 1.86 for mortality, and pooled mean difference, 1.26; 95% CI: 0.07 to 2.45 for on-scene time). Conclusions: In prehospital settings, the present study showed no advantages of ALS on the outcomes in patients with trauma compared to BLS.

Project description:ObjectivesThe objective of this study was to evaluate the effect of nontechnical skills (NTS) training on performance in advanced life support (ALS) simulation. Furthermore, we aimed to determine the ideal frequency of training sessions for an optimal retention and the value of debriefing.MethodsA systematic search was performed using PubMed, EMBASE, WoS, ERIC, CINAHL, and the Cochrane Library conducted through August 1, 2018. All primary studies mentioning NTS in ALS education were included. Three reviewers independently extracted data on study design and outcome. The MERSQI approach was used to evaluate the overall quality of evidence.ResultsOf the 10,723 identified articles, 40 studies were included with a combined total of 3,041 participants, ranging from students to experts. Depending on the focus of the study, articles were categorized in NTS (n = 25), retention (n = 8), and feedback (n = 10). Incorporating NTS during ALS simulation showed significant improvements in timing for performing critical first steps. Furthermore, good leadership skills had a favorable effect on overall technical performance and teamwork during simulation improved team dynamics and performance. Finally, debriefing also had a beneficial effect on team performance. One particular type of debriefing does not appear to be superior to other types of debriefing.ConclusionTeam simulation training resulted in improved NTS and a reduction in the time required to complete a simulated cardiac arrest. Therefore, a formal NTS program should be introduced into ALS courses. Feedback and repetitive practice are key factors to train NTS. The impact of training on team behaviors can persist for at least 3 to 6 months. In conclusion, understanding and improving NTS may help to create more effective teams. The effect on patient outcome requires further investigation.
