Knowledge of the national emergency telephone number and prevalence and characteristics of those trained in CPR in Queensland: baseline information for targeted training interventions

Global prevalence of basic life support training: A systematic review and meta-analysis

BACKGROUND AND AIMS

Out-of-hospital cardiac arrest exerts a large disease burden, which may be mitigated by bystander cardiopulmonary resuscitation and automated external defibrillation. We aimed to estimate the global prevalence and distribution of bystander training among laypersons, which are poorly understood, and to identify their determinants.

METHODS

We searched electronic databases for cross-sectional studies reporting the prevalence of bystander training from representative population samples. Pooled prevalence was calculated using random-effects models. Key outcome was cardiopulmonary resuscitation training (training within two-years and those who were ever trained). We explored determinants of interest using subgroup analysis and meta-regression.

RESULTS

28 studies were included, representing 53,397 laypersons. Among national studies, the prevalence of cardiopulmonary resuscitation training within two-years and among those who were ever trained, and automated external defibrillator training was 10.02% (95% CI 6.60-14.05) and 39.64% (95%CI 29.11-50.67), and 15.70% (95% CI 10.17-22.18) respectively. Subgroup analyses by continent revealed pooled prevalence estimates of 31.58% (95%CI 18.70-46.09), 52.62% (95%CI 38.40-66.63), 18.93 (95%CI 0.00-62.94), 64.97% (95%CI 64.00-65.93), and 50.56% (95%CI 47.57-53.54) in Asia, Europe, Middle East, North America, and Oceania respectively, with significant subgroup differences (p<0.01). A country's income and cardiopulmonary resuscitation training (ever trained) (p=0.033) were positively correlated. Similarly, this prevalence was higher among the employed (p<0.00001) and highly educated (p<0.00001).

CONCLUSIONS

Large regional variation exists in data availability and bystander training prevalence. Socioeconomic status correlated with prevalence of bystander training, and regional disparities were apparent between continents. Bystander training should be promoted, particularly in Asia, Middle East, and low-income regions. Data availability should be encouraged from under-represented regions.

Global prevalence of cardiopulmonary resuscitation training among the general public: a scoping review

A scoping review was conducted to identify, map, and analyze international evidence from studies investigating the prevalence of community cardiopulmonary resuscitation (CPR) training. We searched major bibliographic databases and grey literature for original studies evaluating the prevalence of CPR training in the general population. Studies published from January 2000 to October 2020 were included without language or publication type restrictions. Seventy-three eligible papers reported a total of 61 population-based surveys conducted in 29 countries. More than three-fourths of the surveys were conducted in countries with high-income economies, and none in low-income countries. Over half of the surveys were at a subnational level. Globally, the proportion of laypeople trained in CPR varied greatly (median, 40%). For high-income countries, the median percentage was twice as high as that of upper middle-income countries (50% vs. 23%). The studies used heterogeneous survey methods and reporting patterns. Key methodological aspects were frequently not described. In summary, few studies have assessed CPR training prevalence among the general public. The rates of resuscitation training for the vast majority of countries remain unknown. High heterogeneity of studies precludes a reliable interpretation of the research. International Utstein-style consensus guidelines are needed to inform future research and reporting of public resuscitation training worldwide.

Laypeople's activity for seeking telephone number of EMS before and during the COVID-19 outbreak: An analysis of web search data

Objective

To explore trends and patterns of laypeople's activity for seeking telephone number of emergency medical services (EMS) based on analysis of online search traffic, including changes of the search activity with onset of the coronavirus disease 2019 (COVID-19) outbreak, in five countries – the United States of America (USA), India, Brazil, the United Kingdom (UK) and Russia.

Methods

Google Trends (GT) country-level data on weekly relative search volumes (RSV) for top queries to seek EMS number were examined for January 2018–October 2021, including a comparison of RSVs between pre-COVID-19 period (January 2018–October 2019) and COVID-19 period (January 2020–October 2021), and evaluation of temporal associations of RSVs with weekly numbers of new COVID-19 cases.

Results

The countries demonstrated diverse patterns of the search activity with significantly different mean RSVs (the USA 1.76, India 10.20, Brazil 2.51, the UK 6.42, Russia 56.79; p < 0.001). For all countries excepting the USA mean RSVs of the COVID-19 period were significantly higher compared with the pre-COVID-19 ones (India +74%, Brazil +148%, the UK +22%, Russia +9%; p ≤ 0.034), and exhibited positive correlations with numbers of new COVID-19 cases, more pronounced for 2021 (India r_S = 0.538, Brazil 0.307, the UK 0.434, Russia 0.639; p ≤ 0.045).

Conclusion

Laypeople's activity for seeking EMS telephone number greatly varies between countries. It clearly responds to the spread of COVID-19 and could be reflective of public need for obtaining emergency help. Further studies are required to establish the role of GT for conducting real-time surveillance of population demand for EMS.

Mapping the public first-aid training landscape: a scoping review

While the public can play a vital role in saving lives during emergencies, intervention is only effective if people have the skills, confidence, and willingness to help. This review employs a five-stage framework to systematically analyse first aid and emergency helping literature from 22 countries (predominately in Asia, Australia, Europe, and the United States). The review covers 54 articles that investigate public first-aid knowledge and uptake of first-aid training (40); public confidence in first-aid skills and willingness to help during an emergency (21); and barriers to or enablers of learning first aid and delivering first aid in an emergency (25). The findings identify high levels of perceived knowledge, confidence, and willingness to help, supporting the contention that the public can play a vital role during an emergency. However, the findings also point to low uptake levels, low tested skill-specific knowledge, and barriers to learning first aid and helping, indicating that the first-aid training landscape is in need of improvement.

Knowledge of and willingness to perform Hands-Only cardiopulmonary resuscitation among college students in Malaysia

Worldwide, millions of people die of sudden cardiac arrest every year. This is partly due to limited and sometimes ineffective bystander cardiopulmonary resuscitation (CPR). The need for mouth-to-mouth contact, fear of causing harm, litigation, and the complexity of delivering CPR are the main deterrents. In view of this, the basic life support algorithm has been simplified and lay rescuers are encouraged to perform Hands-Only CPR.The objective of this study is to assess knowledge on and willingness to perform Hands-Only CPR among Malaysian college students and to determine the relationship between the two.In an online self-administered survey, college students responded to a questionnaire on demographics, exposure to CPR, knowledge on Hands-Only CPR, and their willingness to perform Hands-Only CPR in 5 different scenarios (family members or relatives, strangers, trauma victims, children, and elderly people).Data for 393 participants were analyzed. For knowledge, the mean score was 8.6 ± 3.2 and the median score was 9. In the sample, 27% of the respondents did not attend any CPR training before, citing that they were unsure where to attend the course. The knowledge score among those who attended CPR training (M = 3.6, S = 2.9) was significantly higher compared to those who did not (M = 6.7, S = 3.0). Out of the 393 participants, 67.7%, 55%, 37.4%, 45%, and 49.1% were willing to perform Hands-Only CPR on family members or relatives, strangers, trauma victims, children, and elderly people, respectively. There were significant associations (P < .001) between knowledge and willing to perform Hands-Only CPR on family members or relatives (OR = 1.32, 95% CI 1.43, 1.43), strangers (OR = 1.31, 95% CI 1.21, 1.42), trauma victims (OR = 1.21, 95% CI 1.12, 1.31), children (OR = 1.28, 95% CI 1.19, 1.39), and elderly people (OR = 1.36 95% CI 1.25, 1.48).Based on this study, knowledge on Hands-Only CPR among local college students is not encouraging. Not many know where to attend such courses. There was significant association between knowledge and willingness to perform Hands-Only CPR.

Characteristics Associated with First Aid and Cardiopulmonary Resuscitation Training and Use in Queensland, Australia

INTRODUCTION

First aid, particularly bystander cardiopulmonary resuscitation (CPR), is an important element in the chain of survival. However, little is known about what influences populations to undertake first aid/CPR training, update their training, and use of the training.

OBJECTIVES

The aim of this study was to explore the characteristics of people who have first aid/CPR training, those who have updated their training, and use of these skills.

METHODS

As part of the 2011 state-wide, computer-assisted telephone interviewing (CATI) survey of people over 18 years of age living in Queensland, Australia, stratified by gender and age group, three questions about first aid training, re-training, and skill uses were explored.

RESULTS

Of the 1,277 respondents, 73.2% reported having undertaken some first aid/CPR training and 39.5% of those respondents had used their first aid/CPR skills. The majority of respondents (56.7%) had not updated their first aid/CPR skills in the past three years, and an additional 2.5% had never updated their skills. People who did not progress beyond year 10 in school and those in lower income groups were less likely to have undertaken first aid/CPR training. Males and people in lower income groups were less likely to have recently updated their first aid/CPR training. People with chronic health problems were in a unique demographic sub-group; they were less likely to have undertaken first aid/CPR training but more likely to have administered first aid/CPR.

CONCLUSION

Training initiatives that target people on the basis of education level, income group, and the existence of chronic health problems might be one strategy for improving bystander CPR rates when cardiac arrest occurs in the home.Franklin RC, Watt K, Aitken P, Brown LH, Leggat PA.

Stop the bleed campaign: A qualitative study from our experience from the middle east

Background

Bleeding due to unintentional injuries are a leading cause of death in the younger population. The immediate involvement of lay bystanders has been proven to be imperative in outcomes, however, there still is less than 30% of out-of-hospital resuscitation attempts initiated by them.

Study design

The Stop the Bleed campaign was initiated in Kuwait in September-2017, with the aim to raise awareness and train the general public on emergency situations. A survey questionnaire was distributed to a sample of 150 participants to assess their comprehension.

Results

A total of 1531 participants were trained by the campaign. More than half of the participants have had no previous training of any sort for emergency situations, with the majority (86%) of those queered expressing desire to learn about how to deal with trauma and bleeding cases. After training, most participants were able to demonstrate knowledge of how to deal with unstoppable bleeding, know where and when to place a tourniquet, knew how to respond to epistaxis, and the ability to recognize signs of internal bleeding, with 89% expressing that the 'Stop the Bleed' campaign was useful for promoting health and raising awareness on safety of individuals.

Conclusion

With the appropriate first-aid training and skill retention, lay members of the public can potentially contribute to a positive and important post-trauma medical response.

Cardiopulmonary arrest in primary care clinics: more holes than cheese: a survey of the knowledge and attitudes of primary care physicians regarding resuscitation

BACKGROUND

Patients experiencing pre-arrest symptoms may first refer to their primary care physician. The study's aim was to determine the likelihood that a patient undergoing out-of-hospital cardiac arrest will receive appropriate resuscitation efforts in a primary care clinic in a country with a directive that clinics maintain resuscitation equipment and physicians undergo periodic resuscitation training.

METHODS

An anonymous, 23-question online cross-sectional survey was created and administered to primary care physicians working in community clinics (10/1/2015-5/3/2015). Recruitment was accomplished by posting a link to the survey to all physicians listed as registered Society of Family Medicine members and in other online forums dedicated to residents and board-certified specialists in family medicine in Israel. The primary outcome measure was the proportion of respondents whose responses indicate that they fulfill all conditions for performing resuscitation.

RESULTS

Of approximately 2400 potential respondents, 185 replied to the survey; the study's findings should be viewed as preliminary. Respondents' characteristics were generally similar to those of the study population, but respondents had a higher rate of family medicine specialists. Respondents were mostly female (n = 108, 58%) Israeli graduates who have practiced medicine for > 10 years (72%, n = 134). 55% (n = 101) had undergone basic life support (BLS) training within < 2 years. Although just 5% (n = 10) estimated call-to-Emergency Medical Service (EMS) arrival time to their clinic to be <5 min, only 64% (n = 119) knew the telephone number for summoning EMS. Most confirmed the existence of a resuscitation cart in their clinic (85%, n = 157); 68% confirmed the presence of a defibrillator (n = 126). Most respondents were aware of the location of the defibrillator in their clinic (67%, n = 123), stated its accessibility during working hours (63%, n = 116), and 56% (n = 103) knew how to use it. Only 28% of the questionnaires indicated that all requirements for mounting an effective BLS response had been fulfilled.

CONCLUSIONS

The study suggests that many primary care clinics are under-equipped and their physicians are under-prepared to initiate life-saving services. Steps must be taken to rectify this situation. In addition, to develop more reliable estimates of the phenomena reported in this preliminary study, these issues should be re-examined in the context of a high response rate physician survey.

A nationwide survey of first aid training and encounters in Norway

Background

Bystander first aid can improve survival following out-of-hospital cardiac arrest or trauma. Thus, providing first aid education to laypersons may lead to better outcomes. In this study, we aimed to establish the prevalence and distribution of first aid training in the populace, how often first aid skills are needed, and self-reported helping behaviour.

Methods

We conducted a telephone survey of 1000 respondents who were representative of the Norwegian population. Respondents were asked where and when they had first aid training, if they had ever encountered situations where first aid was necessary, and stratified by occupation. First aid included cardio-pulmonary resuscitation (CPR) and basic life support (BLS). To test theoretical first aid knowledge, respondents were subjected to two hypothetical first aid scenarios.

Results

Among the respondents, 90% had received first aid training, and 54% had undergone first aid training within the last 5 years. The workplace was the most common source of first aid training. Of the 43% who had been in a situation requiring first aid, 89% had provided first aid in that situation. There were considerable variations among different occupations in first aid training, and exposure to situations requiring first aid. Theoretical first aid knowledge was not as good as expected in light of the high share who had first aid training. In the presented scenarios 42% of respondent would initiate CPR in an unconscious patient not breathing normally, and 46% would provide an open airway to an unconscious road traffic victim. First aid training was correlated with better theoretical knowledge, but time since first aid training was not.

Conclusions

A high proportion of the Norwegian population had first aid training, and interviewees reported high willingness to provide first aid. Theoretical first aid knowledge was worse than expected. While first aid is part of national school curriculum, few have listed school as the source for their first aid training.

Public knowledge of cardiopulmonary resuscitation in Republic of Slovenia

AIM

In a case of cardiac arrest lay people in Republic of Slovenia rarely start basic life support procedures. The aim of this study was to determine the extent of knowledge about and attitude towards cardiopulmonary resuscitation in lay population.

METHOD

A cross-sectional telephone survey using computer-assisted telephone interview method was performed in August and September 2006. Questionnaire contained sections regarding participant demographics, knowledge of cardiac arrest signs and of cardiopulmonary resuscitation procedures (CPR), previous courses of CPR training, and the awareness of emergency phone contact number.

RESULTS

We interviewed 500 subjects. Nearly 70% of subjects had attended courses on CPR, but nearly 80% of them did so more than 10 years ago. Less than half of the subjects knew that CPR include rescue breathing (47%) and chest compressions (44.6%). Subjects who passed training on CPR knew that twice more often (p < 0.001). Knowledge on resuscitation skills was generally poor. Only 1.2% knew the rate of chest compressions, 2.2% knew the correct compressions-to-ventilations ratio in adult CPR, and only 3 out of 500 subjects (0.6%) knew both. Correct site and correct strength for chest compressions were stated in 37.6% and 13.0%, respectively. Both the correct site and the correct strength were stated more often in CPR-trained group (p = 0.002 and p = 0.02, respectively).

CONCLUSION

Lay public in Republic of Slovenia has poor knowledge on CPR. Knowledge is better in trained versus untrained individuals. Educational campaign in the community would improve response to cardiac emergencies.

Significant improvement of the quality of bystander first aid using an expert system with a mobile multimedia device

OBJECTIVE

Better quality bystander first-aid could improve outcome rates for emergency victims significantly. In this case-control study, we hypothesised that expert knowledge presented step-by-step to untrained helpers using a personal digital assistant (PDA), would improve the quality of bystanders basic life support.

METHOD

We confronted 101 lay-helpers with two standard emergency situations. (1) An unconscious trauma victim with severe bleeding. (2) Cardiopulmonary resuscitation (CPR). Performance was assessed using an Objective Structured Clinical Examination (OSCE). One group was supported by a PDA providing visual and audio instructions, whereas the control group acted only with their current knowledge. The expert system was programmed in HTML-code and displayed on the PDA's Internet browser.

RESULTS

The maximum score obtainable was 24 points corresponding to optimal treatment. The control group without the PDA reached 14.8+/-3.5 (mean value+/-standard deviation), whereas the PDA supported group scored significantly higher (21.9+/-2.7, p<0.01). The difference in performance was measurable in all criteria tested and particularly notable in the items: placing in recovery position, airway management and quality of CPR.

CONCLUSION

The PDA based expert system increased the performance of untrained helpers supplying emergency care significantly. Since Internet compatible mobile devices have become widely available, a significant quality improvement in bystander first-aid seems possible.

A nationwide survey of CPR training in Sweden: foreign born and unemployed are not reached by training programmes

AIM

To determine the number of CPR trained adults in Sweden, and the willingness of the non-trained population to attend a CPR course. An additional purpose was to investigate differences related to sex, age, residential area, socio-economic classification and country of origin.

METHODS

Five thousand adults in Sweden were surveyed, which yielded 3167 valid responses, a response rate of 63%. The sample was selected at random and stratified to correlate to the geographic distribution of the population.

RESULTS

The mean (S.D.) age was 46 (16) years, 54% of the respondents were females and 11% were people of foreign origin. Forty-five percent had participated in some form of CPR training. Younger respondents, those living in rural areas, those born in Sweden, employees, students and military conscripts were trained more frequently in CPR. Of the respondents with no CPR training, 50% expressed a willingness to attend a course. The most common reason for not being trained in CPR was that the respondent did not know such courses existed or that they did not know where to go for training.

CONCLUSION

Somewhere between 30 and 45% of the adult population of Sweden had participated in CPR training. Half of the non-trained population was willing to learn CPR but frequently did not know that such courses existed or where they were held. Elderly people, people of foreign origin, or those not included in the workforce were less likely to have participated in CPR training.

Possibilities for, and obstacles to, CPR training among cardiac care patients and their co-habitants

AIM

To investigate the level of cardiopulmonary resuscitation (CPR) training among cardiac patients and their co-habitants and to describe the possibilities for, and obstacles to, CPR training among this group.

METHODS

All patients admitted to a coronary care unit during a four-month period were considered for participation in an interview study. Out of 401 patients, 268 were co-habiting. This study deals with these subjects.

RESULTS

According to the answers given by the patients, 46% of the patients and 33% of the co-habitants had attended a CPR course at some time. Among those who had not previously attended a course, 58% were willing to attend, and 60% of the patients whose co-habitant had not received CPR education, wanted him or her to attend a course. The major obstacle to CPR training was the patient's own medical status. The major obstacle to the co-habitant's participation was the patient's doubts concerning their partner's physical ability or willingness to participate. Younger persons were more often willing to undergo training than older persons (p < 0.0001). Of those patients who had previously attended a course or who were willing to undergo training, 72% were prepared to do so together with their co-habitant. A course specially designed for cardiac patients and their relatives was a possible alternative for 75% of those willing to participate together with their co-habitant.

CONCLUSIONS

Two-thirds of the patients did not believe that their co-habitant had taken part in CPR training. More than half of these would like their co-habitant to attend such a course. Seventy-two percent were willing to participate in CPR instruction together with their co-habitant. Major obstacles to CPR training were doubts concerning the co-habitant's willingness or physical ability and their own medical status.

First-aid training and capabilities of the lay public: a potential alternative source of emergency medical assistance following a natural disaster

Basic first-aid skills can be useful in treating minor injuries that commonly result from natural disasters in the United States. Yet there has been insufficient research on training and competence in first-aid skills among community residents. This study utilises panel data for 414 adults in Los Angeles, California, who were interviewed within three years of the 1994 Northridge earthquake and re-interviewed in 1999 after the El Ninõ winter of 1997-98. Descriptive, bivariate and multivariate analyses were performed. Results showed that 24 percent of the members of the sample had received first-aid training since their Northridge earthquake interview. First-aid training, particularly recent training, was associated with greater perceived first-aid skills, as well as with increased expected and actual employment of those skills. With the appropriate training and skill retention, lay members of the public can potentially contribute to a post-disaster medical response.

CPR training in households of patients with chest pain

The objectives of this study are to (1). quantify prior cardiopulmonary resuscitation (CPR) training in households of patients presenting to the Emergency Department (ED) with or without chest pain or ischaemic heart disease (IHD); (2). evaluate the willingness of household members to undertake CPR training; and (3). identify potential barriers to the learning and provision of bystander CPR. A cross-sectional study was conducted by surveying patients presenting to the ED of a metropolitan teaching hospital over a 6-month period. Two in five households of patients presenting with chest pain or IHD had prior training in CPR. This was no higher than for households of patients presenting without chest pain or IHD. Just under two in three households of patients presenting with chest pain or IHD were willing to participate in future CPR classes. Potential barriers to learning CPR included lack of information on CPR classes, perceived lack of intellectual and/or physical capability to learn CPR and concern about causing anxiety in the person at risk of cardiac arrest. Potential barriers to CPR provision included an unknown cardiac arrest victim and fear of infection. The ED provides an opportunity for increasing family and community capacity for bystander intervention through referral to appropriate training.

Factors influencing Queenslanders' willingness to perform bystander cardiopulmonary resuscitation

STUDY OBJECTIVE

The chances of surviving an out-of-hospital cardiac arrest (OHCA) are greatly increased if a bystander provides cardiopulmonary resuscitation (CPR) while awaiting the arrival of the emergency medical services. Over 50% of adult Queenslanders have been trained in CPR at some time in the past, however, little is known about the factors that affect their willingness to perform CPR.

METHOD

A random survey of 4480 Queensland residents was conducted to address this question.

RESULTS

The survey indicated that the most common barriers to performing CPR were a fear of disease, visible blood and perceived danger. In contrast, respondents indicated that they were more likely to administer CPR if the respondent knew the victim, the victim would die if CPR was not administered, and respondents believed that they possessed the necessary skills to perform CPR. A majority (84%) of respondents indicated that they were at least likely to administer CPR. A logistic regression analysis revealed that the respondents most likely to perform CPR were males, those who were married or in a de facto relationship, those in paid employment, smokers, those recently trained in CPR, prospective organ donors, those who cited no barriers to CPR and those who cited one or more factors that would facilitate CPR.

CONCLUSIONS

This study indicates that there is considerable variation in Queenslanders' willingness to perform bystander CPR. Public health education campaigns aimed at correcting inaccurate perceptions of risk and addressing other barriers to bystander CPR would promote its use in response to OHCA.
