The nationwide impact of COVID-19 on life support courses. A retrospective evaluation by Resuscitation Council UK.

Aim: To determine the impact of the COVID-19 pandemic on Resuscitation Council UK Advanced Life Support (ALS) and Immediate Life Support (ILS) course numbers and outcomes. Methods: We conducted a before-after study using course data from the Resuscitation Council UK Learning Management System between January 2018 and December 2021, using 23 March 2020 as the cut-off between pre- and post-pandemic periods. Demographics and outcomes were analysed using chi-squared tests and regression models. Results: There were 90,265 ALS participants (51,464 pre-; 38,801 post-) and 368,140 ILS participants (225,628 pre-; 142,512 post-). There was a sharp decline in participants on ALS/ILS courses due to COVID-19. ALS participant numbers rebounded to exceed pre-pandemic levels, whereas ILS numbers recovered to a lesser degree with increased uptake of e-learning versions. Mean ALS course participants reduced from 20.0 to 14.8 post-pandemic (P < 0.001).Post-pandemic there were small but statistically significant decreases in ALS Cardiac Arrest Simulation Test pass rates (from 82.1 % to 80.1 % (OR = 0.90, 95 % CI = 0.86-0.94, P < 0.001)), ALS MCQ score (from 86.6 % to 86.0 % (mean difference = -0.35, 95 % CI -0.44 to -0.26, P < 0.001)), and overall ALS course results (from 95.2 %to 94.7 %, OR = 0.92, CI = 0.85-0.99, P = 0.023). ILS course outcomes were similar post-pandemic (from 99.4 % to 99.4 %, P = 0.037). Conclusion: COVID-19 caused a sharp decline in the number of participants on ALS/ILS courses and an accelerated uptake of e-learning versions, with the average ALS course size reducing significantly. The small reduction in performance on ALS courses requires further research to clarify the contributing factors.

Feedback in advanced life support: A quality improvement initiative.

AIM: To identify participant, course characteristics and centre factors associated with participant satisfaction and ALS outcomes. METHODS: 17,690 participants enrolled on ALS courses between 1st December 2017 and 30th November 2018. Participant, course and centre characteristics were explored in relation to course learning outcomes and participant experience. Learning outcomes were assessed through a post-course MCQ score and technical and non-technical skills through a cardiac arrest simulation test (CAS-Test). Successful completion of knowledge and skill-based assessments led to overall course success. Participant feedback was collected on a post-course questionnaire. Multivariable analyses identified variables associated with course outcomes and feedback. Adjusted funnel plots compared inter-course centre outcomes. RESULTS: Mean post-course MCQ score was 86.7% (SD = 6.7). First attempt CAS-Test pass rate was 82.6% and overall course pass rate 94.4%. Participant characteristics explained the majority of variation between course centres. Characteristics associated with knowledge, skill and course outcomes were age, prior experience, pre-course MCQ score, course type, ethnicity, place of work, profession and seniority. Feedback scores were predicted by course type, pre-course MCQ, ethnicity, profession and seniority. CONCLUSION: This is the first study to identify variables associated with both ALS feedback scores and assessment outcomes. It has demonstrated that both course outcomes and participant experience are similar across a large number of course centres. Identifying the demographic traits of participants who may struggle with ALS, may enable bespoke support from an earlier stage. Analysis of feedback scores and outcomes enables ongoing appraisal and targeted improvement of the Resuscitation Council UK ALS course.

e-Learning in Advanced Life Support-What factors influence assessment outcome?

AIM: To establish variables which are associated with favourable Advanced Life Support (ALS) course assessment outcomes, maximising learning effect. METHOD: Between 1 January 2013 and 30 June 2014, 8218 individuals participated in a Resuscitation Council (UK) e-learning Advanced Life Support (e-ALS) course. Participants completed 5-8h of online e-learning prior to attending a one day face-to-face course. e-Learning access data were collected through the Learning Management System (LMS). All participants were assessed by a multiple choice questionnaire (MCQ) before and after the face-to-face aspect alongside a practical cardiac arrest simulation (CAS-Test). Participant demographics and assessment outcomes were analysed. RESULTS: The mean post e-learning MCQ score was 83.7 (SD 7.3) and the mean post-course MCQ score was 87.7 (SD 7.9). The first attempt CAS-Test pass rate was 84.6% and overall pass rate 96.6%. Participants with previous ALS experience, ILS experience, or who were a core member of the resuscitation team performed better in the post-course MCQ, CAS-Test and overall assessment. Median time spent on the e-learning was 5.2h (IQR 3.7-7.1). There was a large range in the degree of access to e-learning content. Increased time spent accessing e-learning had no effect on the overall result (OR 0.98, P=0.367) on simulated learning outcome. CONCLUSION: Clinical experience through membership of cardiac arrest teams and previous ILS or ALS training were independent predictors of performance on the ALS course whilst time spent accessing e-learning materials did not affect course outcomes. This supports the blended approach to e-ALS which allows participants to tailor their e-learning experience to their specific needs.

E-learning in advanced life support--an evaluation by the Resuscitation Council (UK).

AIM: To descriptively analyse the outcomes following the national roll out of an e-Learning advanced life support course (e-ALS) compared to a conventional 2-day ALS course (c-ALS). METHOD: Between 1st January 2013 and 30th June 2014, 27,170 candidates attended one of the 1350 Resuscitation Council (UK) ALS courses across the UK. 18,952 candidates were enrolled on a c-ALS course and 8218 on an e-ALS course. Candidates participating in the e-ALS course completed 6-8h of online e-Learning prior to attending the 1 day modified face-to-face course. Candidates participating in the c-ALS course undertook the Resuscitation Council (UK) 2-day face-to-face course. All candidates were assessed by a pre- and post-course MCQ and a practical cardiac arrest simulation (CAS-test). Demographic data were collected in addition to assessment outcomes. RESULTS: Candidates on the e-ALS course had higher scores on the pre-course MCQ (83.7%, SD 7.3) compared to those on the c-ALS course (81.3%, SD 8.2, P<0.001). Similarly, they had slightly higher scores on the post-course MCQ (e-ALS 87.9%, SD 6.4 vs. c-ALS 87.4%, SD 6.5; P<0.001). The first attempt CAS-test pass rate on the e-ALS course was higher than the pass rate on the c-ALS course (84.6% vs. 83.6%; P=0.035). The overall pass rate was 96.6% on both the e-ALS and c-ALS courses (P=0.776). CONCLUSION: The e-ALS course demonstrates equivalence to traditional face-to-face learning in equipping candidates with ALS skills when compared to the c-ALS course. Value is added when considering benefits such as increased candidate autonomy, cost-effectiveness, decreased instructor burden and improved standardisation of course material. Further dissemination of the e-ALS course should be encouraged.

Anaemia and malnutrition in children aged 0-59 months on the Bijagós Archipelago, Guinea-Bissau, West Africa: a cross-sectional, population-based study.

BACKGROUND: Childhood malnutrition is the leading risk factor for the global burden of disease. Guinea-Bissau is a politically unstable country with high levels of childhood malnutrition and mortality. AIM: To determine the nutritional status of children on three remote islands of the Bijagós Archipelago, Bubaque, Rubane and Soga, and to identify factors associated with malnutrition and anaemia in this population in order to provide a baseline for future public health interventions. METHODS: A cross-sectional, population-based, door-to-door household survey of randomly selected households was undertaken to collect data on children aged 0-59 months (n = 872). Dietary information was collected using a validated questionnaire. Anthropometric measurements were collected using World Health Organization techniques. Capillary blood samples were analysed using a Hemocue®, with anaemia defined as Hb<11 g/dl. RESULTS: The prevalences of stunted, wasted and underweight children were 21.8%, 9.4% and 3.7%, respectively. These figures indicate moderate chronic malnutrition. The significant predictor variables for stunting were: age in months (OR 1.03), rural residence (OR 2.32), anaemia (OR 3.55) and residence on Soga island (OR 0.44). Stunting was more prevalent in males (25.4%) than in females (18.6%) (P = 0.03). The prevalence of anaemia was 80.2%. Age (OR 0.96), male gender (OR 1.81) and stunting (OR 2.87) were significant predictors. The Minimum Acceptable Diet was achieved by only 8.7% of children. CONCLUSION: The prevalence of malnutrition on the Bijagós Archipelago is less than half that on the mainland. This study is the first to determine the prevalence of anaemia in Guinea-Bissau, which, at 80.2%, is of severe public health concern. Future research should focus on the aetiology of stunting and anaemia, especially the contribution of infectious diseases and mother-child interaction. Iron supplementation should be strongly considered in this population.

Effect of level and source of dietary fiber on food intake in the dog.

The effects of dietary fiber on challenge meal intake and on the perception of hunger in dogs were evaluated. A program of testing variants of a standard low energy diet, to which one of five fiber containing raw materials was added, was undertaken. Diets were fed to a group of six dogs for 12-d periods in a latin square design and in amounts that corresponded to the food allowance for weight reduction. Behavioral characteristics of dogs were recorded on videotape for 30-min periods after introduction of test diets. On two occasions during each 12-d feeding period dogs were presented with a challenge meal. At the end of each 12-d feeding period all dogs entered a 6-d washout period. There was no significant effect of diet on the intake of the challenge meal or on intake of food during the subsequent washout period. In addition, diet had no apparent effect on the perception of hunger, as represented by behavioral characteristics during the 30-min period after presentation of test diets. It was concluded that inclusion of moderate levels of raw materials, composed primarily of insoluble fiber, in a commercial low energy diet had no apparent beneficial effects on satiety, when fed to dogs on an energy intake corresponding to allowances for weight reduction.

The reaction of mitochondrial L-3-glycerophosphate dehydrogenase with various electron acceptors.

1. The kinetics of the reaction of glycerophosphate dehydrogenase with a variety of electron acceptors have been investigated. 2. In all cases the reaction mechanism appears to involve a free modified-enzyme intermediate. 3. With some electron acceptors, the maximum velocity of the reaction and the K(m) for glycerophosphate are independent of the nature of the electron acceptor, whereas in other cases this is not so. 4. The reaction mechanism of the enzyme extracted with phospholipase A instead of with Triton X-100 is of a similar type.

Preparation and some properties of L-3-glycerophosphate dehydrogenase from pig brain mitochondria.

1. A method is described for extraction and partial purification of mitochondrial l-3-glycerophosphate dehydrogenase from pig brain. 2. By the criteria that have so far been applied, the extraction and purification procedures do not modify the activity of the enzyme towards artificial electron acceptors. 3. The amounts of acid-liberatable flavine and iron in the preparation were measured. 4. A study was made of the effects of various analogues of l-3-glycerophosphate on the activity of the enzyme.
