Bleeding control measures performed by members of the public can prevent trauma deaths. Equipping public spaces with bleeding control kits facilitates these actions. We modeled a mass casualty incident to investigate the effects of public bleeding control kit location strategies.

We developed a computer simulation of a bomb exploding in a shopping mall. We used evidence and expert opinion to populate the model with parameters such as the number of casualties, the public’s willingness to aid, and injury characteristics. Four alternative placement strategies of public bleeding control kits in the shopping mall were tested: co-located with automated external defibrillators (AEDs) separated by 90-second walking intervals, dispersed throughout the mall at 10 locations, located adjacent to 1 exit, located adjacent to 2 exits.

Placing bleeding control kits at 2 locations co-located with AEDs resulted in the most victims surviving (18.2), followed by 10 kits dispersed evenly throughout the mall (18.0). One or 2 kit locations placed at the mall’s main exits resulted in the fewest surviving victims (15.9 and 16.1, respectively).

Co-locating bleeding control kits with AEDs at 90-second walking intervals results in the best casualty outcomes in a modeled mass casualty incident in a shopping mall.

During an exercise-related sudden cardiac arrest, bystander automated external defibrillator use occurred in a median of 31%. The present study conducted in France evaluated the feasibility and impact of a brief intervention by general practitioners (GPs) to increase awareness about first aid/CPR training among amateur sportspeople.

In 2018, 49 French GPs proposed a brief intervention to all patients who attended a consultation in order to obtain a medical certificate attesting their fitness to participate in sports. The brief intervention included two questions (Have you been trained in first aid? Would you like to attend a first aid course?) and a flyer on first aid. The GPs’ opinion of the feasibility of the brief intervention was evaluated during a subsequent interview (primary objective). The percentage of sportspeople who started a first aid/CPR course within three months was used as a measure of the effectiveness of the brief intervention (secondary objective).

Among 929 sportspeople, 37% were interested in first aid training and received the flyer (4% of these started a training course within three months of the brief intervention, a training rate that was 10 times greater than among the general French population), 56% were already trained, and 7% were not interested. All GPs found the brief intervention feasible and fast (<3 min for 80% of GPs). We conclude the brief intervention to promote first aid/CPR awareness is easy to use and may be an effective although limited means of promoting CPR training. It opens a previously unexplored avenue for GP involvement in promoting training.

The ever-growing penetration of internet and mobile technologies into society suggests that people will increasingly use web searches to seek health-related information, including advice on first aid in medical emergencies. When a bystander is incompetent in first aid and has no immediate support from Emergency Medical Services (EMS), as it happens in low-resource settings or in disasters, instructions found online could be the sole driver for administering first aid before arrival of professional help.

The aim of this study was to evaluate quality of advice on first aid generated by a web search engine’s question-answering system (QAS) in response to search queries concerning provision of help in common health emergencies.

In December 2022-January 2023, an English-language search was carried out in Google with ten queries based on the keyword combinations (what to do OR how to help) AND (bleeding OR chest pain OR choking OR not breathing OR seizure). The search engine’s QAS responses (up to 11 per search query) were evaluated for compliance with the International Federation of Red Cross First Aid Guidelines 2020 using the pre-developed checklists.

Out of 98 QAS items generated by Google, 67.3% (n = 66) were excluded, mainly because the QAS answers did not address original queries. Eligible unique QAS responses (n = 27) showed poor coverage of the guideline-compliant instructions on first aid. Mean percentage of QAS responses providing a first aid instruction with complete adherence to the guidelines varied from 0.0 for choking to 19.5 for seizure. Only three (11.1%) QAS responses contained an explicit instruction to access EMS, while 66.7% (n = 18) included directions either contradictory to the guidelines and potentially harmful (eg, use of home remedies in chest pain) or inapplicable for an untrained person (eg, use of tourniquet in bleeding).

Although the search engine’s QAS responds to user’s inquiries concerning assistance in health emergencies, the QAS-generated answers, as a rule, omit potentially life-saving evidence-based instructions on first aid and oftentimes give advices noncompliant with current guidelines or inadequate for untrained people, and thus create risks for causing harm to a victim.

Prompt prehospital care (PHC) is essential for improving outcomes of road traffic accident victims. Previous studies in Nigeria show that little or no PHC is delivered to trauma victims by first responders. This study was conducted to assess police officers’ experience with FA/BLS, to identify gaps in their FA/BLS knowledge and skills, and assess police stations’ FA/BLS equipment capacity for PHC of road traffic accident victims.

This cross-sectional study was conducted among 428 GD police in Abuja between November and December 2018. Respondents were selected using stratified random sampling with proportional allocation method. Data were collected using self-administered electronic semi-structured questionnaires. Data analysis was done using STATA v 14.0 (StataCorp, College Station, TX). Chi-square and multivariate logistic regression were used to assess associations.

We analyzed data from 419 respondents. Almost all (90.2%) of the police were aware of FA/BLS. The proportion of police with poor, fair, and good knowledge and skills on FA/BLS were 15.3%, 79.0%, and 5.7%, respectively. Tertiary (OR = 3.35, 95% CI: 1.01-11.11, P = 0.048) and postgraduate (OR = 6.89, 95% CI: 1.63-29.19, P = 0.009) levels of education had statistically significant association with good knowledge and skills.

This highlights the need to implement an educational intervention to increase FA/BLS competencies within the first responder population.

Epistaxis can be life-threatening. Simple first aid management can stem bleeding. This study compared knowledge of first aid management methods of epistaxis between the general public and healthcare workers.

A cross-sectional study of 100 healthcare workers and 103 adult members of the public was conducted at a large London teaching hospital. Respondents completed a survey assessing knowledge on nasal pinching site, head tilt and appropriate adjunct treatment use for first aid management of epistaxis.

Twenty-four per cent and 68 per cent of healthcare workers compared with 25.2 per cent and 37.9 per cent of the public answered correctly on nasal pinching position and head tilt position, respectively, with a statistical difference for head tilt position. Two per cent, 2 per cent and 24 per cent of healthcare workers mentioned ice use on the nose, ice use in the mouth or ice use but not site, respectively, compared with 0 per cent, 0 per cent and 4.9 per cent of the public, with a statistical difference for ice without site.

Healthcare workers and the public lack knowledge on first aid management of epistaxis. Improved education on first aid management is required, targeting healthcare workers and the public.

The majority of injury deaths occur outside health facilities. However, many low- and middle-income countries (LMICs) continue to lack efficient Emergency Medical Services (EMS). Understanding current first aid practices and perceptions among members of the community is vital to strengthening non-EMS, community-based prehospital care.

This study sought to determine caregiver first aid practices and care-seeking behavior for common household child injuries in rural communities in Ghana to inform context-specific interventions to improve prehospital care in LMICs.

A cluster-randomized, population-based household survey of caregivers of children under five years in a rural sub-district (Amakom) in Ghana was conducted. Caregivers were asked about their practices and care-seeking behaviors should children sustain injuries at home. Common injuries of interest were burns, laceration, choking, and fractures. Multiple responses were permitted and reported practices were categorized as: recommended, low-risk, or potentially harmful to the child. Logistic regression was used to examine the association between caregiver characteristics and first aid practices.

Three hundred and fifty-seven individuals were sampled, representing 5,634 caregivers in Amakom. Mean age was 33 years. Most (79%) were mothers to the children; 68% had only completed basic education. Most caregivers (64%-99%) would employ recommended first aid practices to manage common injuries, such as running cool water over a burn injury or tying a bleeding laceration with a piece of cloth. Nonetheless, seven percent to 56% would also employ practices which were potentially harmful to the child, such as attempting manual removal of a choking object or treating fractures at home without taking the child to a health facility. Reporting only recommended practices ranged from zero percent (burns) to 93% (choking). Reporting only potentially harmful practices ranged from zero percent (burns) to 20% (fractures). Univariate regression analysis did not reveal consistent associations between various caregiver characteristics and the employment of recommended only or potentially harmful only first aid practices.

Caregivers in rural Ghanaian communities reported using some recommended first aid practices for common household injuries in children. However, they also employed many potentially harmful practices. This study highlights the need to increase context-appropriate, community-targeted first aid training programs for rural community populations of LMICs. This is important as the home-based care provided for injured children in these communities might be the only care they receive.

Most medical emergencies requiring first-aid occur at home. Little is known about the prevalence of these medical emergencies.

The objective of this study is to describe medical emergencies occurring at people’s homes requiring first aid; characteristics, burdens and impact on functional outcome, and to address the national public knowledge and practice of first aid.

A confidential, cross-sectional survey, primarily based on the 2015 American Heart Association (AHA) and American Red Cross first aid guidelines, was conducted among adults (>18 years) from 12 educational centers, under the Ministry of Awqaf and Islamic affairs, State of Kuwait.

A total of 3000 self-administered questionnaires were distributed from September 16 2019 to November 30, 2019. The response rate was 34% (n = 1033 participants) of which 1% (n = 11) were partially answered questionnaires leaving 1022 questionnaires for valid statistical analysis. The prevalence of medical emergencies was 118.5 out of 100000 per year and the level of public knowledge was 19%. Medical emergencies were more likely to occur in Hawali province (49%, n = 149), women were more likely to encounter medical emergencies (78%, n = 238). Victims above 18 years of age were more likely to experience hypoglycemia (39%, n = 55) and children were more likely to suffer from hypoglycemia (19%, n = 22) or burns (17%, n = 20). Compliance with First aid guidelines was seen in hypoglycemia (31%, n = 44) but lacking in burn incidents (44%, n = 15). Participants called the ambulance in seizures (50%, n = 13), with 62% of medical emergencies requiring attendance at a health-care facility and 29% requiring hospital admission. Of the victims, 15% missed school or a day of work, and 25% had impaired functional outcomes.

Medical emergencies occurring at home are relatively common in Kuwait, and public training on first aid is low. Kuwait has unique medical emergencies, with hypoglycemia, seizures and burns being the most frequent emergencies that occur at home. These emergencies cause a burden on the health-care system with a quarter of them having negative impact on the victim’s functional outcome.

Individuals on anticoagulation therapy are at increased risk of bleeding, including epistaxis. There is a lack of available reversal agents for novel oral anticoagulation therapy.

This paper reviews the current literature on epistaxis in the context of novel oral anticoagulation use, in order to recommend guidelines on management.

A comprehensive search of published literature was conducted to identify all relevant articles published up to April 2019.

Patients on oral anticoagulation therapy are over-represented in individuals with epistaxis. Those on novel oral anticoagulation therapy were more likely to relapse compared to patients on classic oral anticoagulants or non-anticoagulated patients. Idarucizumab is an effective antidote for bleeding associated with dabigatran use. Recommendations for epistaxis management in patients on novel oral anticoagulation therapy are outlined.

Clinicians need to be aware of the potential severity of epistaxis and the increased likelihood of recurrence. High-quality studies are required to determine the efficacy and safety of andexanet alfa and ciraparantag, as well as non-specific reversal agents.

Triage at mass gatherings in Australia is commonly performed by staff members with first aid training. There have been no evaluations of the performance of first aid staff with respect to diagnostic accuracy or identification of presentations requiring ambulance transport to hospital.

It was hypothesized that triage decisions by first aid staff would be considered correct in at least 61% of presentations.

A retrospective audit of 1,048 presentations to a single supplier of event health care services in Australia was conducted. The presentations were assessed based on the first measured set of physiological parameters, and the primary triage decision was classified as “expected” if the primary and secondary triage classifications were the same or “not expected” if they differed. The performance of the two triage systems was compared using area under the receiver operating characteristic curve (AUROC) analysis.

The expected decision was made by first aid staff in 674 (71%) of presentations. Under-triage occurred in 131 (14%) presentations and over-triage in 142 (15%) presentations. The primary triage strategy had an AUROC of 0.7644, while the secondary triage strategy had an AUROC of 0.6280, which was significantly different (P = .0199).

The results support the continued use of first aid trained staff members in triage roles at Australian mass gatherings. Triage tools should be simple, and the addition of physiological variables to improve the sensitivity of triage tools is not recommended because such an approach does not improve the discriminatory capacity of the tools.

Epinephrine has been recommended for out-of-hospital cardiac arrest (OHCA) resuscitation for nearly one century, but its efficacy and safety remain unclear in the literature. The primary aim of this review was to determine whether epinephrine increases the return of spontaneous circulation in OHCA patients.

A systematic review and meta-analysis were conducted using the following databases: MEDLINE, EMBASE, and CENTRAL, from their inception until October 2018. All the randomized controlled trials (RCTs) were included. Observational studies, case reports, case series, and non-systematic reviews were excluded.

Two trials including 8,548 patients were eligible for inclusion in the data synthesis. In patients who received epinephrine during OHCA, the incidence of return of spontaneous circulation was increased, with an odds ratio (95%CI) of 4.25 (3.79-4.75), P <.001, high-quality of evidence. The number of patients transported to hospital was increased in patients who had prehospital epinephrine, with an odds ratio (95%CI) of 2.31 (2.11-2.53), P <.001, high-quality of evidence. The prehospital use of epinephrine was associated with an increased survival to hospital discharge, the odds ratio (95%CI) being 1.43 (1.10-1.87), P = .008, moderate-quality of evidence. No significant effect was noted on the favorable neurologic state of patient at hospital discharge, with an odds ratio (95%CI) of 1.21 (0.90-1.64), P = .21, moderate-quality of evidence.

This meta-analysis suggests that the prehospital use of epinephrine increases return of spontaneous circulation, transport of patients to hospital, and survival to hospital discharge for OHCA. However, no significant effects on favorable neurologic function at hospital discharge were demonstrated. The general quality of evidence ranged from moderate to high.

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.

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.

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.

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.

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.

In July 2016, a mass-casualty stabbing attack took place at a facility for disabled persons located in Sagamihara City (Kanagawa Prefecture, Japan). The attack resulted in 45 casualties, including 19 deaths. The study hospital dispatched physicians to the field and admitted multiple casualties. This report aimed to review the physicians’ experiences and to provide insights for the formulation of response measures for similar incidents in the future.

This incident involved 30 emergency teams and 12 fire department teams, including those from neighboring fire departments. Five physicians from three medical institutions, including the study hospital, entered the field. The Simple Triage and Rapid Treatment (START) method was used on the field. The final field triage category count was: 20 red, four yellow, two green, and 19 black tags. All the casualties (n = 26) except for the 19 black tag casualties were transported to one of six neighboring medical institutions.

The median age of the transported casualties was 41 years (interquartile range [IQR] = 35.5 – 42.0). Three casualties (21.4%) were in hemorrhagic shock on arrival at the hospital. Twelve patients had multiple cervical stab wounds (median four wounds; IQR = 3.75 – 6.0). A total of 91.7% of these stab wounds were in mid-neck Zone II region. Of the 12 patients with cervical stab wounds, four (33.3%) required emergency surgery, and the rest were sutured on an out-patient basis. One patient had already been sutured on the field. All patients requiring emergency surgery had deep wounds, including those of the carotid vein, thyroid gland, nerves, and the trachea. Eight of the casualties were hospitalized at the study institution. Five of them were admitted to the intensive care unit. There were no deaths among the casualties transported to the hospitals.

Regional core disaster medical hospitals must take on a central role, particularly in the case of local disasters. Horizontal communication and interactions should be reinforced by devising protocols and conducting joint training for effective inter-department collaborations on the field.

School-aged children are a risk group in terms of accidents and injuries, and these factors may be the primary causes of death in children. Teachers have important roles in preventing accidents and injuries and giving first aid. The purpose of this research was to identify situations in which teachers most frequently encounter the need to administer first aid to children and whether the teachers performed the correct application in these events.

This descriptive study was conducted with 331 teachers in a city in the Central Anatolia Region. The study was approved by the local ethics committee and the participants.

Of the 45.3% teachers educating children ages 6 to 15 years, 81.0% of the teachers were familiar with first aid, but only 23.0% claimed to have an adequate knowledge. In the previous year, situations that had required first aid included epistaxis (75.2%), abdominal pain (49.2%), and vomiting (39.2%). The study also investigated any accidents and injuries occurring, their causes, and the teachers’ interventions following the accidents and injuries. It was found that teachers had information about first aid, but they did not trust themselves enough to practice it.

Understanding the causes of accidents and injuries, finding preventive measures, and updating teachers’ knowledge about this subject are important to provide a safe educational environment. (Disaster Med Public Health Preparedness. 2019;13:456-462)

Mass gatherings are complex events that present a unique set of challenges to attendees’ health and well-being. There are numerous factors that influence the number and type of injuries and illnesses that occur at these events, including weather, event and venue type, and crowd demographics and behavior.

While the impact of some factors, such as weather conditions and the availability of alcohol, on patient presentations at mass gatherings have been described previously, the influence of many other variables, including crowd demographics, crowd behavior, and event type, is poorly understood. Furthermore, a large number of studies reporting on the influence of these variables on patient presentations are based on anecdotal evidence at a single mass-gathering event.

Data were collected by trained fieldworkers at 15 mass gatherings in South Australia and included event characteristics, crowd demographics, and weather. De-identified patient records were obtained from on-site health care providers. Data analysis included the calculation of patient proportions in each variable category, as well as the total number of patient presentations per event and the patient presentation rate (PPR).

The total number of expected attendees at the 15 mass gatherings was 303,500, of which 146 presented to on-site health care services. The majority of patient presentations occurred at events with a mean temperature between 20°C and 25°C. The PPR was more than double at events with a predominantly male crowd compared to events with a more equal sex distribution. Almost 90.0% of patient presentations occurred at events where alcohol was available.

The results of the study suggest that several weather, crowd, and event variables influence the type and number of patient presentations observed at mass-gathering events. Given that the study sample size did not allow for these interactions to be quantified, further research is warranted to investigate the relationships between alcohol availability, crowd demographics, crowd mobility, venue design, and injuries and illnesses.
