Application and analysis of competition based training mode for first aid skills in residency program / 中华急诊医学杂志

Objective:To explore the model of first aid skills training based on competition.Method:The second-year residents who participated in the competition in 2021 ( n = 142) were selected. According to whether they attended BLS training in the first year, they were divided into group A ( n = 88) who attended BLS training and group B ( n = 54) who did not. Chi-square test, T test, Wilcoxon rank sum test and Logistic regression were used in our study. Results:There was no significant difference in gender and specialty between both groups (female, 62.5% vs. 68.5%, P= 0.466; TCM, 50% vs. 53.7%, P= 0.668), but the real resuscitation experience of group A was more than that of group B (40.9% vs. 9.3%, P= 0.000). The qualified rate of CPR and the compression score in group A was higher than that in group B [(81.8% vs. 61.1%, P = 0.006; (30±5) vs. (25 ±10), P= 0.001], including compression frequency, depth, rebound and compression/respiration rate (73.9% vs. 55.6%, P= 0.024; 88.6% vs. 70.4%, P= 0.006; 96.6% vs. 87%, P= 0.031). In the theoretical examination, the correct rates of electrocardiogram [(53.63±2.9)% vs. (50.44±2.57)%] and first aid medication [(57.38±3.55)%, P = 0.001] in the two groups were significantly lower than the qualified rate. After adjusting other factors, Logistic regression analysis showed that the CPR qualification rate in group A was 2.769 times higher than that in group B ( P= 0.015, 95% CI 1.215~6.311) Conclusions:The first aid skills training mode based on competition can objectively reflect first aid skills level of residents. We found that the quality of CPR skills was not related to gender, specialty and real CPR experiences but experience of BLS training was an independent influencing factor. And how to identify and manage arrhythmias and how to choose different emergency drugs are urgent emergency skills for residents to improve.

Assessment of Cardiopulmonary Resuscitation Knowledge and Attitude Amongst Interns and Junior Residents of Tertiary Care Centre

Introduction: Cardiopulmonary resuscitation (CPR) is a life saving procedure and adequate knowledge and skills related to CPR are essential for all medical students. This study was undertaken to compare knowledge and practice related to updated CPR guidelines by American Heart Association (AHA) 2020 between junior residents and interns. Methods:This is a questionnaire-based study prepared on Google form consisting of 22 questions on CPR. Total of 124 participants included 41 junior residents and 83 interns. They were advised to read questions carefully and allowed to tick one best response among the options. Results: An average overall correct response from both the group was 14.48 (65.81 %). Among theory knowledge-based questions junior residents had an average of 8.707 correct answers out of 11 (79.15%) which is more correct answers than interns who have average 5.90 correct (53.63%). Similarly, in terms of practical knowledge, junior residents had an average score 9.682 out of 11 (88.026%) compared to interns who had an average of 6.518 out of 11 (59.27%). Conclusion: The study showed poor knowledge about CPR among the interns. More practical based teaching should be employed in MBBS curriculum. Periodical reinforcement and refresher courses should be part of curriculum.

Understanding the Negative Public Perception on Vaccination in West Coast and East Coast Peninsular Malaysia

@#Introduction: Vaccination is a biological process that improves immunity level of an individual towards certain diseases. Vaccination is generally given to all newborn and kids. Most countries oblige their citizens to be vaccinated as early as new-born age. The aim of this research is to study the perception on vaccination intake and the associated factors that lead to its refusal among parents in east coast and west coast peninsular Malaysia. Methods: Primary data were collected using self-administered questionnaire and were distributed to assess the study objectives. Total 240 questionnaires were distributed equally in west coast and east coast study area. Questionnaire consists of demographic data, perception aspects and factors that may lead to the negative perceptions. Results: There is significant association between perception and religion, education level and side effect factor in east coast with majority of the respondents are Muslims (40.83%) while there is no significant association between education level and side effect factor (p>0.1) in west coast with majority of respondents are Muslims (51.67%) too. This study found that perception regarding vaccination is influenced by the religion restrictions in east coast of peninsular Malaysia and not in west coast region. The other factors associated with vaccination refusal varies according to education level, and regional basis. Conclusion: Most of the respondents who have negative perception regarding vaccination are from East Coast region as they are more prone into Islamic teachings. All the possible factors of vaccination refusal are accepted by the respondents but varies in its prevalence as the leading factor determined that caused the vaccination refusal are religion restriction and the least percentage for the factor is time restriction.

Retention of Cardiopulmonary Resuscitation (CPR) Knowledge among Undergraduate Teacher Student in Malaysian University

@#Introduction: There is global support for the teaching of cardiopulmonary resuscitation (CPR) in schools, and teachers are expected to play a leading role in a medical emergency. For effective resuscitation, retention of CPR knowledge after training is paramount. This study aimed at assessing the retention of CPR knowledge among student teachers at pre-, post-immediate, 8th-, and 14th-week post-training. Method: A quasi-experimental study using non-probability convenience sampling was conducted to select 41 respondents from the Department of Physical and Health Education, Faculty of Education (UiTM). A validated American Heart Association's 2015 Basic Life Support (BLS) multiple-choice questions (MCQ) were utilised to measure the retention of knowledge among the participants. Results: This study demonstrated a significant lack of CPR knowledge during pre-test with the mean scores of M=8.02 despite half of the participants had prior knowledge in CPR. Nevertheless, the paired t-test revealed a significant improvement in the post-scores following the intervention at M=16.20, t(40) = -18.56, p < 0.001, and d=3.91. The one-way RM-ANOVA results showed a decline in the retention rate at the 8th week (M=13.06; p < 0.001) and an improvement at the 14th weeks (M= 5.74; p < 0.001). Conclusion: The knowledge of CPR among the student teachers following the intervention program was appropriate, but the deterioration of retention suggested that all student teachers should undergo comprehensive routine CPR courses to avoid the immediate loss of CPR knowledge and skills. The governing bodies in Malaysia should implement CPR training as part of the curriculum for teachers.

Knowledge, Attitude, and Practice on the Basic Life Support among Medical Interns of the Philippine General Hospital

@#Objective. This study aimed to assess the knowledge, attitude, and practice on the Basic Life Support (BLS) among the Philippine General Hospital medical interns, compare the scores between trained and untrained interns, and determine the proportion of respondents with updated BLS training. Methods. This was a cross-sectional study using a thirty-five item questionnaire on the knowledge, attitude, and practice of medical interns at the Philippine General Hospital on the BLS. Results. A total of 262 interns were included in the study. Although the mean knowledge scores of untrained and trained medical interns did not differ significantly (7.00 vs. 7.30, p=0.1637), more than 20% committed mistakes on questions on the following: jaw-thrust, rescue breaths, defibrillation, and CPR check. Generally, interns followed the BLS guidelines in their practice and had a positive attitude towards BLS. However, only 37% of trained participants had training within the past two years. Conclusion. Most medical interns have a fair knowledge on BLS regardless of training status and adhere to them in practice. Since the training duration did not affect their knowledge scores, initial training in medical school and continuous exposure in the wards may have provided adequate BLS reinforcement. Recertification may not be needed during their formative years in medical school.

Preparación de los colegios y profesores de educación física en prevención de muerte súbita y soporte vital básico / Competence of schools and physical education teachers for sudden death prevention and basic life support

OBJETIVO: Conocer el nivel de preparación de colegios y profesores de educación física en prevención de muerte súbita (MS) y soporte vital básico, incluyendo disponibilidad y uso del desfibrilador externo automático (DEA). MÉTODOS: Estudio descriptivo de corte transversal, en profesores de educación física de establecimientos educacionales de distintos tipos de sostenedores (municipales, subvencionados y particulares) de Santiago, Chile, a través de un cuestionario online. Se analizaron datos demográficos del profesor, antecedentes de preparación y disposición de reanimación cardiopulmonar (RCP), presencia y uso de DEA y preparación del establecimiento ante un caso de MS. RESULTADOS: De 97 profesores encuestados, 71,1% no se siente capacitado para realizar RCP a pesar que un 70% del total ha realizado un curso. La disposición para realizar reanimación en aquellos que han realizado un curso, es 99%, comparado con 83% en quienes no lo han realizado (p=0,003). Existe una marcada diferencia en disponibilidad de DEA según tipo de sostenedor (52,4% en particulares, 29,6% en municipales y 15% en subvencionados, p=0,001), pero transversalmente no saben cómo utilizarlo (42,9 %, 40,7% y 25%, p=0,43). La mayoría de los colegios no cuenta con un plan de acción ante MS. CONCLUSIONES: Los colegios y profesores de educación física tienen una preparación insuficiente y desactualizada en prevención de muerte súbita y soporte vital básico, con una distribución heterogénea de DEA en establecimiento según tipo de sostenedor.

OBJECTIVE: To assess the competence of schools and physical education teachers in the prevention of sudden death (SD) and basic life support meassures, including availability and use of the automatic external defibrillator (AED). METHODS: A descriptive cross-sectional study included physical education teachers from different Schools (public, subsidized and private) in Santiago, Chile. An online questionnaire was applied including demographic data of the teacher, comentence and willingness to perform cardiopulmonary resuscitation (CPR), presence and use of AED and school preparation in case of a SD. RESULTS: From a total of 97 teachers surveyed do not feel capable of performing CPR, in spite of the fact that 70% of them completed a CPR course. Among those who took a course, their willingness to perform resuscitation was 99%, compared to 83% en those not having taken the course (p = 0.003). There was a marked difference in DEA availability according to class of school (private 52,4%, public 29,6 subsidized 15%, p=0,001), but the knowledge on how to use de DEA was uniformly insufficient (42,9 %, 40,7% and 25%, p=0,43) Most schools do not have a protocol to face SD. CONCLUSIONS: We observed that schools and physical education teachers have an insufficient and outdated preparation in sudden death prevention and basic life support. The availability of AED differed according to the class of establishment.

Evaluation of Basic Life Support Knowledge and Skills of Healthcare and Non-healthcare Providers

Aim: Immediate bystander cardiopulmonary resuscitation (CPR) significantly improves survival after a sudden cardiopulmonarycollapse. This study assessed the basic life support (BLS) awareness, knowledge, attitude, and performance of healthcareproviders (HCP) and non-HCP before and after CPR training.Materials and Methods: This study included 4625 participants. Participants completed a pre-test to assess their knowledgeand 3 h training course that provided a theoretical background on sudden cardiac death and a hands-on CPR tutorial. Theywere asked to perform BLS on a manikin to simulate an unconscious scenario before the training. Afterward, participantsencountered the same scenario and completed a questionnaire of their post-training knowledge.Results: A total of 4625 participants were included in this study. Of which 56.54% (n = 2615) were HCP and 43.45% (n = 2010)were non-HCP. There is a significant increase in knowledge of BLS among non-HCP which is clearly evident in pre-trainingand post-training evaluation (written and hands-on). Only 0.62% employees are able to perform BLS in the correct sequencebefore the training and 76.7% employees after the training. None of the students performed BLS in the correct sequence beforethe training and 60.85% students performed well after the training. Among HCP, only 12.08% were able to perform BLS in thecorrect sequence before the training and 94.8% after the training.Conclusion: Performing BLS and attending BLS training plays a key role in attaining BLS knowledge by both healthcare andnon-HCP.

Knowledge and Attitude of Basic Life Support in the Community of Dammam City, Saudi Arabia

Aim: The purpose of the study was to evaluate the knowledge and attitude of the community about basic life support (BLS) living in Dammam, Saudi Arabia. Furthermore, evaluation of the limitations of training on BLS skills was another study objective. Materials and Methods: This cross-sectional study was conducted between February 2018 and January 2019 in Dammam, Saudi Arabia. Three hundred seventy-two randomly selected individuals participated in the study. Their knowledge and attitude toward BLS was gathered through a questionnaire that got filled by interviewers. The only inclusion criteria were the age, the participant should have been at least 18 years old. Results: The average knowledge score of a participant was 2.02 (±1.4) out of 7, where males and Saudi participants had significantly better knowledge about BLS compared to females and non-Saudi. Furthermore, significantly small number of participants had cardiopulmonary resuscitation (CPR) training. However, their attitude was more positive and they were willing to receive CPR training. Conclusion: Attitude toward acquiring knowledge about CPR was very positive. However, their knowledge about the topic was insufficient. People should be aware of the importance of having this training and this can be done through media and social media. Knowledge about the availability of programs at nearby places can also help to motivate people.

Availability of basic life support courses for the general populations in India, Nigeria and the United Kingdom: An internet-based analysis / 世界急诊医学杂志（英文）

@#BACKGROUND: The number of lay people willing to attempt cardiopulmonary resuscitation (CPR) in real life is increased by effective education in basic life support (BLS). However, little is known about access of general public to BLS training across the globe. This study aimed to investigate availability and key features of BLS courses proposed for lay people in India, Nigeria and the United Kingdom (UK). METHODS: A Google search was done in December 2018, using English keywords relevant for community resuscitation training. Ongoing courses addressing BLS and suitable for any adult layperson were included in the analysis. On-site training courses were limited to those provided within the country’s territory. RESULTS: A total of 53, 29 and 208 eligible courses were found for India, Nigeria and the UK, respectively. In the UK, the number of courses per 10 million population (31.5) is 79 and 21 times higher than that in India (0.4) and Nigeria (1.5). Course geography is limited to 28% states and one union territory in India, 30% states and the Federal Capital Territory in Nigeria. In the UK, the training is offered in all constituent countries, with the highest prevalence in England. Courses are predominantly classroom-based, highly variable in duration, group size and instructors’ qualifi cations. For India and Nigeria, mean cost of participation is exceeding the monthly minimum wage. CONCLUSION: In contrast to the UK, the availability and accessibility of BLS courses are critically limited in India and Nigeria, necessitating immediate interventions to optimize community CPR training and improve bystander CPR rates.

Basic life support skills and health emergency preparedness among school teachers in India: a questionnaire-based study in an urban population

Background: The purpose of this study was to assess basic life support (BLS) knowledge and attitudes among school teachers in India, and to elicit school preparedness in handling medical emergencies.Methods: Using a two stage sampling technique, 198 teachers from 10 schools in a metropolitan city participated in the study. A pre-validated questionnaire was administered to assess school teacher knowledge of BLS, and the principals of the schools provided information regarding the facilities available to manage health emergencies.Results: Although more than half of the surveyed teachers were aware of the term BLS, only 7 percent were trained in resuscitation. Thirteen percent of teachers had encountered emergencies in the classroom. Most of the schools maintained a basic first aid kit but lacked other equipment necessary to manage more serious health emergencies.Conclusions: Our study suggests that although teachers may be aware of BLS, they lack formal training and schools may be poorly equipped to tackle medical emergencies. It is therefore necessary to regularly train teachers in BLS and ensure that schools are provided with resuscitation equipment to enable them to handle health emergencies in children.

Evaluation of the Effectiveness of Basic Life Support Courses among Health Care Professionals at the Ministry of National Guard Health Affairs

Objectives: Previous studies have indicated that cardiopulmonary resuscitation by some healthcare professionals does not measure up to current standards. We evaluated the attitude, knowledge, and behavior of healthcare professionals towards basic life support courses at the Postgraduate Training Center in Riyadh, Saudi Arabia. Methods: Crosssectional and longitudinal analyses were performed. Data were initially collected after each basic life support course over 11-months. A follow-up questionnaire was sent 6-months after each course. The Kirkpatrick model was used to assess the effectiveness of the course for improving attitudes, knowledge, and behavior. Results: Total 455 trainees (87.5%) and 53 instructors (88.3%) responded at baseline. The mean attitude and knowledge scores were 55.6 ± 6.09 and 92.1 ± 7.06, respectively. After 6-months, 193 individuals responded. The mean knowledge score difference was -9.27 ± 12.9. The mean behavior score was 43.2 ± 4.29 at baseline; after 6-months, 26.4% of participants showed a decline in confidence in their cardiopulmonary resuscitation skills. Attitude and behavior scores were correlated (p<0.001). Conclusion: Healthcare professionals had generally positive attitudes and behavior concerning basic life support. There was a clear deterioration in basic life support knowledge 6-months after the course. To ensure the delivery of high-quality cardiopulmonary resuscitation, frequent training and knowledge assessment are imperative.

Basic life support knowledge of family medicine residents at joint program of family medicine in Jeddah Saudi Arabia, 2017

Background: Healthcare professionals are expected to have adequate knowledge of basic and advanced cardiac life support to revive unresponsive patients. Little is known about that in health care professionals in Saudi Arabia.Methods: we conducted this study in the joint program of family medicine to evaluate knowledge of physicians about basic life support, and to identify factors associated with the differences in their knowledge. Through a cross-sectional analytic study, all physicians in the Joint Program of Family Medicine in Jeddah were included in the study. For collection of data, a validated self-administered questionnaire was used.Results: Out of responding physicians (n=150), females constituted 117 (78%), their mean age accounted for 27.3±2.2 years. all physicians (99.3%) reported that they had attended BLS courses before. Out of a maximum of “13”, the mean score of correct answers accounted for 6.2±1.6, only 18.7% of the physicians achieved above average scores. Only qualification had statistically significant impact on the level of knowledge, the average score percentage was higher among those who have MBBS qualification only compared to their colleagues who have postgraduate degrees (48.3%±11.57% vs 39.2%±13.78%) p<0.05.Conclusions: Physicians in the Joint Program of Family Medicine have deficient level of knowledge about BLS, despite of their previous BLS training. Frequent training is strongly recommended to sustain adequate level of knowledge about BLS.

Comparing Teachers and Medical Students as Trainers of Cardiopulmonary Resuscitation (CPR) among Secondary School Students

@#Bystander rate of cardiopulmonary resuscitation (CPR) is still low worldwide because of inadequate skills and knowledge. Training the public on CPR is one of the methods to increase the bystander CPR rate. This study aimed to compare the efficacy in acquiring and retaining CPR skills and knowledge among secondary school students in Klang Valley trained by school teachers and medical students. We recruited five school teachers and five medical students as trainers. They were trained in several sessions by American Heart Association (AHA)-certified instructors using the video-assisted CPR training module. The recipients were 44 secondary school students divided between the teacher’s group and the medical student’s group. We compared knowledge and psychomotor skills between these two groups prior, immediately after and at three months after CPR training. Students in the teacher’s group showed a higher increase in knowledge comparable to the medical student’s group (median score difference 3 vs 2, p>0.05) and in psychomotor skill (median score difference 5 vs. 7, p<0.05). The level of knowledge and skills decreased after 3 months but remained significantly higher than at baseline for both groups. In conclusion, teachers could provide CPR training to their students as effective and retainable as medical students. This study aims to create an opportunity to teach CPR to the public in a larger scale.

BACKGROUND@# The aim of the study is to evaluate the theoretical knowledge and psychomotor skill acquisition of basic life support (BLS) by a group of secondary school students in Nigeria pre and post BLS training.@*METHODS@# This was quasi-experimental study design with 210 participants. They were taught on adult BLS and all the participants practiced BLS on a Resusci-Anne manikin immediately after the training. Data were collected using American Heart Association (AHA) structured questionnaire and psychomotor skills checklist for BLS at baseline, and post BLS training.@*RESULTS@# The pre-training knowledge score was 1.9±1.4. This increased after the BLS training to 11.4±2.4, and the mean difference between the pre and post BLS training scores was 9.48571. Pre-training psychomotor skill score was 0.00±0.00, this increased to 8.9±1.9 after the training, and the mean difference was 8.90000. The knowledge and psychomotor skill difference between pre and post BLS training was significant (P<0.000).@*CONCLUSION@# Most Nigerian secondary school students were not knowledgeable about BLS. Therefore, there is need for the creation of more awareness among the students.

Do medical students studying in the United Kingdom have an adequate factual knowledge of basic life support? / 世界急诊医学杂志（英文）

BACKGROUND@# Healthcare professionals have a duty to maintain basic life support (BLS) skills. This study aims to evaluate medical students' factual knowledge of BLS and the training they receive.@*METHODS@# A cross-sectional, closed-response questionnaire was distributed to the first- and fourth-year students studying at institutions in the United Kingdom. The paper questionnaire sought to quantify respondent's previous BLS training, factual knowledge of the BLS algorithm using five multiple choice questions (MCQs), and valuate their desire for further BLS training. Students received 1 point for each correctly identified answer to the 5 MCQ's.@*RESULTS@#A total of 3,732 complete responses were received from 21 medical schools. Eighty percent (n=2,999) of students completed a BLS course as part of their undergraduate medical studies. There was a significant difference (P<0.001) in the percentage of the fourth-year students selecting the correct answer in all the MCQ's compared to the first-year students except in identifying the correct depth of compressions required during CPR (P=0.095). Overall 10.3% (95% CI 9.9% to 10.7%) of respondents correctly identified the answer to 5 MCQ's on BLS: 9% of the first-year students (n=194) and 12% of the fourth-year students (n=190). On an institutional level the proportion of students answering all MCQ's correctly ranged from 2% to 54% at different universities. Eighty-one percent of students (n=3,031) wished for more BLS training in their curriculum.@*CONCLUSION@# Factual knowledge of BLS is poor among medical students in the UK. There is a disparity in standards of knowledge across institutions and respondents indicating that they would like more training.

Application of a Dual-Dispatch System for Out-of-Hospital Cardiac Arrest Patients: Will More Hands Save More Lives?

BACKGROUND: Recovery after out-of-hospital cardiac arrest (OHCA) is difficult, and emergency medical services (EMS) systems apply various strategies to improve outcomes. Multi-dispatch is one means of providing high-quality cardiopulmonary resuscitation (CPR), but no definitive best-operation guidelines are available. We assessed the effects of a basic life support (BLS)-based dual-dispatch system for OHCA. METHODS: This prospective observational study of 898 enrolled OHCA patients, conducted in Daegu, Korea from March 1, 2015 to June 30, 2016, involved patients > 18 years old with suspected cardiac etiology OHCA. In Daegu, EMS started a BLS-based dual-dispatch system in March 2015, for cases of cardiac arrest recognition by a dispatch center. We assessed the association between dual-dispatch and OHCA outcomes using multivariate logistic regressions. We also analyzed the effect of dual-dispatch according to the stratified on-scene time. RESULTS: Of 898 OHCA patients (median, 69.0 years; 65.5% men), dual-dispatch was applied in 480 (53.5%) patients. There was no difference between the single-dispatch group (SDG) and the dual-dispatch group (DDG) in survival at discharge and neurological outcomes (survival discharge, P = 0.176; neurological outcomes, P = 0.345). In the case of less than 10 minutes of on-scene time, the adjusted odds ratio was 1.749 (95% confidence interval [CI], 0.490–6.246) for survival discharge and 6.058 (95% CI, 1.346–27.277) for favorable neurological outcomes in the DDG compared with the SDG. CONCLUSION: Dual-dispatch was not associated with better OHCA outcomes for the entire study population, but showed favorable neurological outcomes when the on-scene time was less than 10 minutes.

Application effects of "two-classroom" teaching mode in basic life support training for medical staffs / 中国中西医结合急救杂志

Objective To investigate the effects of "two-classroom" teaching mode of basic life support (BLS) training on medical staffs. Methods One hundred and ninety-nine medical staffs trained in BLS curriculum education from May to August 2018 were selected as the research subjects. They were divided into two groups according to random number table: "two-classroom" teaching mode group (102) and traditional teaching mode group (97). The medical staffs in the traditional teaching mode group were trained by the traditional mode, while those in the"two-classroom" teaching mode group were trained by the "two-classroom" teaching mode, including the first and second classes; the first class is in-class teaching, using the Chinese version of the original American Heart Association (AHA) textbook, whose contents included basic life support operation video observation, practical operation, scene simulation and other teaching modes to carry out classroom teaching, and the second class was mainly in the extracurricular scene simulation. After the training, the differences in teaching effects regarding theoretical knowledge test scores and operational skills test scores and the degrees of satisfaction between the two groups were compared. Results The theoretical and operational scores of the "two-classroom" teaching mode group were significantly higher than those of the traditional teaching mode group (theoretical scores: 92.10±2.40 vs. 83.4±2.5, operational scores: 91.10±2.20 vs. 82.23±2.13, both P < 0.05). The degree of satisfaction with the BLS training (including 5 parts: controllable learning time, good interaction, cooperative communication, autonomous learning ability, achieving teaching goals) in the medical staffs in the "two-classroom" teaching mode group were higher than those in the traditional teaching mode group (controllable learning time: 98.04±6.35 vs. 83.51±5.27, good interaction: 97.06±6.12 vs. 83.51±5.33, cooperative communication: 96.08±6.07 vs. 73.20±4.96, autonomous learning ability: 96.08±6.15 vs. 73.20±4.28 and achieving teaching goals: 98.04±6.27 vs. 79.38±4.62, all P < 0.05). Conclusion The "two-classroom" teaching mode is a scientific, practical, simple and convenient teaching method, which can improve the theoretical and operational performance grades of trainees, and the medical staffs are well satisfied with the "two-classroom" teaching mode of BLS.
