Background and objective: The prognosis of cardiac arrest victims strongly depends on the prompt provision of Basic Life Support (BLS) maneuvers. Medical students should therefore be proficient in ...this area, but many lack essential BLS knowledge. The goal of this prospective, closed web-based study was to determine whether a short intervention designed to motivate first-year medical students to follow a blended BLS course could lead to a significant improvement in BLS knowledge in the following year. Materials and Methods: A fully automated web-based questionnaire was administered to second-year medical students one year after they had been given the opportunity of following a blended BLS course (e-learning and practice session). The primary outcome was the difference, on a 6-question score assessing essential BLS knowledge, between these students and those from the 2020 promotion since the latter had not been offered the optional BLS course. Results: The score was similar between the two study periods (3.3 ± 0.8 in 2022 vs. 3.0 ± 1.0 in 2020, p = 0.114), but no firm conclusion could be drawn since participation was much lower than expected (17.9% in 2022 vs. 43.7% in 2020, p < 0.001). Therefore, a second questionnaire was created and administered to understand the reasons underlying this low participation. Conclusions: There was a lack of improvement in BLS knowledge in second-year medical students after the introduction of an optional introductory BLS course in the first-year curriculum, but the limited participation rate precludes drawing definitive conclusions. Ineffective communication appears to be the cause of this low participation rate, but a lack of motivation in the aftermath of the COVID-19 pandemic cannot be ruled out. Corrective actions should be considered to enhance communication, restore motivation, and ultimately improve BLS knowledge among medical and dental students.
Shortness of breath is a common complaint among patients in emergency medicine. While most common causes are usually promptly identified, less frequent aetiologies might be challenging to diagnose, ...especially in the pre-hospital setting. We report a case of prehospital dyspnoea initially ascribed to pulmonary oedema which turned out to be the result of profound metformin-associated metabolic acidosis. This diagnosis was already made during the prehospital phase by virtue of arterial blood gas measurement. Pre-hospital measurement of arterial blood gases is therefore feasible and can improve diagnostic accuracy in the field, thus avoiding unnecessary delay and potential harm to the patient before initiating the appropriate therapeutic actions.
Prehospital airway devices are often classified as either basic or advanced, with this latter category including both supraglottic airway (SGA) devices and instruments designed to perform ...endotracheal intubation (ETI). Therefore, many authors analyze the impact of SGA and ETI devices jointly. There are however fundamental differences between these instruments. Indeed, adequate airway protection can only be achieved through ETI, and SGA devices all have relatively low leak pressures which might compromise both oxygenation and ventilation when lung compliance is decreased. In addition, there is increasing evidence that SGA devices reduce carotid blood flow in case of cardiac arrest. Nevertheless, SGA devices might be particularly useful in the prehospital setting where many providers are not experienced enough to safely perform ETI. Compared to basic airway management (bag-valve-mask) devices, SGA devices enable better oxygenation, decrease the odds of aspiration, and allow for more reliable capnometric measurement by virtue of their enhanced airtightness. For all these reasons, we strongly believe that SGA devices should be categorized as "intermediate airway management devices" and be systematically analyzed separately from devices designed to perform ETI.
Patients undergoing emergency general surgery are at high risk of complications and death. Our objectives were to estimate the incidence of emergency general surgery in a Swiss University Hospital, ...to describe the characteristics and outcomes of patients undergoing such procedures, and to study the impact of age on clinical outcomes.
This was a retrospective cohort study of adult patients who visited the emergency department (ED) of Geneva University Hospitals between January 2015 and December 2019. Routinely collected data were extracted from electronic medical records. The primary outcome was the incidence of emergency general surgery among patients visiting the emergency department, defined as general surgery within three days of emergency department admission. We also assessed demographic characteristics, mortality, intensive care unit admission and patient disposition. Multivariable log-binomial regression was used to study the associations of age with intensive care unit (ICU) admission, one-year mortality and dependence at discharge. Age was modelled as a continuous variable using restricted cubic splines and we compared older patients (75th percentile) with younger patients (25th percentile).
Between January 2015 and December 2019, a total of 310,914 emergency department visits met our inclusion criteria. Among them, 3592 patients underwent emergency general surgery within 3 days of emergency department admission, yielding an annual incidence of 116 events per 10,000 emergency department visits (95% CI: 112-119), with a higher incidence in females and young patients. Overall, 5.3% of patients were admitted to ICU, 7.8% were dependent on rehabilitation or assisted living at discharge and 4.8% were dead after one year. Older patients had a higher risk of ICU admission (adjusted risk ratio (aRR) 2.9 1.5-5.4), dependence at discharge (aRR 15.3 5.5-42.4) and one-year mortality (aRR 5.4 2.2-13.4).
Emergency department visits resulting in emergency general surgery are frequent, but their incidence decreases with patient age. Mortality, ICU admission and dependence at discharge following emergency general surgery are more frequent in older patients. Taking into account the increased risk for older patients, a shared process is appropriate for making more informed decisions about their options for care.
Abstract
Background
Frailty assessment by paramedics in the prehospital setting is understudied. The goals of this study were to assess the inter-rater reliability and accuracy of frailty assessment ...by paramedics using the Clinical Frailty Scale (CFS).
Methods
This was a cross-sectional study with paramedics exposed to 30 clinical vignettes created from real-life situations. There was no teaching intervention prior to the study and paramedics were only provided with the French version of the CFS (definitions and pictograms). The primary outcome was the inter-rater reliability of the assessment. The secondary outcome was the accuracy, compared with the expert-based assessment. Reliability was determined by calculating an intraclass correlation coefficient (ICC). Accuracy was assessed through a mixed effects logistic regression model. A sensitivity analysis was carried out by considering that an assessment was still accurate if the score differed from no more than 1 level.
Results
A total of 56 paramedics completed the assessment. The overall assessment was found to have good inter-rater reliability (ICC = 0.87 95%CI 0.81–0.93). The overall accuracy was moderate at 60.6% (95%CI 54.9–66.1) when considering the full scale. It was however much higher (94.8% 95%CI 92.0–96.7 when close assessments were considered as accurate. The only factor associated with accurate assessment was field experience.
Conclusion
The assessment of frailty by paramedics was reliable in this vignette-based study. However, the accuracy deserved to be improved. Future research should focus on the clinical impact of these results and on the association of prehospital frailty assessment with patient outcomes.

Multidisciplinary collaboration is essential to the successful development of serious games, albeit difficult to achieve. In a previous study, the co.LAB serious game design framework was created to ...support collaboration within serious game multidisciplinary design teams. Its use has not yet been validated in a real usage context.
The objective of this study was to perform a first assessment of the impact of the co.LAB framework on collaboration within multidisciplinary teams during serious game design and development.
A mixed methods study was conducted, based on 2 serious game design projects in which the co.LAB framework was used. The first phase was qualitative and carried out using a general inductive approach. To this end, all members of the first serious game project team who used the co.LAB framework were invited to take part in a focus group session (n=6). In a second phase, results inferred from qualitative data were used to define a quantitative instrument (questionnaire) that was designed according to the Checklist for Reporting Results of Internet E-Surveys. Members of both project teams (n=11) were then asked to answer the questionnaire. Quantitative results were reported as median (Q1, Q3), and appropriate nonparametric tests were used to assess between-group differences. Finally, results gathered through the qualitative and quantitative phases were integrated.
In both phases, the participation rate was 100% (6/6 and 11/11). Verbatim transcripts were classified into 4 high level themes: (1) influence on collaborative dimensions; (2) impact on project course, monitoring, and efficiency; (3) qualitative perceptions of the framework; and (4) influence of team composition on the use of the framework. The web-based questionnaire was then developed according to the 7 dimensions of collaboration by Burkhardt et al. In both projects, the co.LAB framework had a positive impact on most dimensions of collaboration during the multidisciplinary design and development of serious games. When all collaborative dimensions were aggregated, the overall impact of the framework was rated on a scale from -42 to 42 (very negative to very positive). The overall median score was 23 (Q1, Q3: 20, 27), with no significant difference between groups (P=.58). Most respondents also believed that all serious game design teams should include a member possessing significant expertise in serious game design to guide the development process.
The co.LAB framework had a positive impact on collaboration within serious game design and development teams. However, expert guidance seems necessary to maximize development efficiency. Whether such guidance can be provided by means of a collaborative web platform remains to be determined.
Lassitude and a rather high degree of mistrust toward the authorities can make regular or overly constraining COVID-19 infection prevention and control campaigns inefficient and even ...counterproductive. Serious games provide an original, engaging, and potentially effective way of disseminating COVID-19 infection prevention and control guidelines. Escape COVID-19 is a serious game for teaching COVID-19 infection prevention and control practices that has previously been validated in a population of nursing home personnel.
We aimed to identify factors learned from playing the serious game Escape COVID-19 that facilitate or impede intentions of changing infection prevention and control behavior in a large and heterogeneous Swiss population.
This fully automated, prospective web-based study, compliant with the Checklist for Reporting Results of Internet E-Surveys (CHERRIES), was conducted in all 3 main language regions of Switzerland. After creating an account on the platform, participants were asked to complete a short demographic questionnaire before accessing the serious game. The only incentive given to the potential participants was a course completion certificate, which participants obtained after completing the postgame questionnaire. The primary outcome was the proportion of participants who reported that they were willing to change their infection prevention and control behavior. Secondary outcomes were the infection prevention and control areas affected by this willingness and the presumed evolution in the use of specific personal protective equipment items. The elements associated with intention to change infection prevention and control behavior, or lack thereof, were also assessed. Other secondary outcomes were the subjective perceptions regarding length, difficulty, meaningfulness, and usefulness of the serious game; impression of engagement and boredom while playing the serious game; and willingness to recommend its use to friends or colleagues.
From March 9 to June 9, 2021, a total of 3227 accounts were created on the platform, and 1104 participants (34.2%) completed the postgame questionnaire. Of the 1104 respondents, 509 respondents (46.1%) answered that they intended to change their infection prevention and control behavior after playing the game. Among the respondents who answered that they did not intend to change their behavior, 86.1% (512/595) answered that they already apply these guidelines. Participants who followed the German version were less likely to intend to change their infection prevention and control behavior (odds ratio OR 0.48, 95% CI 0.24-0.96; P=.04) and found the game less engaging (P<.001). Conversely, participants aged 53 years or older had stronger intentions of changing infection prevention and control behavior (OR 2.07, 95% CI 1.44-2.97; P<.001).
Escape COVID-19 is a useful tool to enhance correct infection prevention and control measures on a national scale, even after 2 COVID-19 pandemic waves; however, the serious game's impact was affected by language, age category, and previous educational training, and the game should be adapted to enhance its impact on specific populations.
Cardiac arrest is the most time-critical emergency medical students and junior physicians may face in their personal or professional life. However, many studies have shown that most of them lack the ...necessary knowledge and skills to efficiently perform resuscitation. This could be related to the fact that advanced cardiovascular resuscitation courses are not always part of the undergraduate medical curriculum.
The aim of this study was to describe the development, pilot implementation, and assessment of an advanced cardiovascular resuscitation course designed to enable senior medical students to manage the initial resuscitation phase in case of cardiac arrest.
An introductory advanced cardiovascular resuscitation course was developed on the initiative of fifth-year medical students, in collaboration with the prehospital emergency medical service team of the Geneva University Hospitals. The 60 slots available to the 157 members of the fifth-year promotion of the University of Geneva Faculty of Medicine were filled in less than 8 hours. This unexpected success prompted the creation of a first questionnaire, which was sent to all fifth-year students to determine the overall proportion of students interested in attending an advanced cardiovascular resuscitation course. This questionnaire was also used to assess basic life support education and experience among course participants. A postcourse questionnaire was used to gather feedback regarding the course and to assess student confidence regarding the resuscitation skills they had been taught.
Out of 157 fifth-year medical students, 73 (46%) completed the first questionnaire. Most thought that the current curriculum did not provide them with enough knowledge and skills regarding resuscitation and 85% (62/73) wished to attend an introductory advanced cardiovascular resuscitation course. All the participants who would have wanted to follow the full Advanced Cardiovascular Life Support course before graduating were set back by its cost (10/10, 100%). Of the 60 students who had registered for the training sessions, 56 (93%) actually attended. The postcourse questionnaire was completed by 42 (87%) students (out of 48 who had registered on the platform). They unanimously answered that an advanced cardiovascular resuscitation course should be part of the standard curriculum.
This study demonstrates the interest of senior medical students in an advanced cardiovascular resuscitation course and their willingness to see such a course integrated as a part of their regular curriculum.
The optimal airway management strategy during cardiopulmonary resuscitation is uncertain. In the case of out-of-hospital cardiac arrest, a high chest compression fraction is paramount to obtain the ...return of spontaneous circulation and improve survival and neurological outcomes. To improve this fraction, providing continuous chest compressions should be more effective than using the conventional 30:2 ratio. Airway management should, however, be adapted, since face-mask ventilation can hardly be carried out while continuous compressions are administered. The early insertion of a supraglottic device could therefore improve the chest compression fraction by allowing ventilation while maintaining compressions. This is a protocol for a multicenter, parallel, randomized simulation study. Depending on randomization, each team made up of paramedics and emergency medical technicians will manage the 10-min scenario according either to the standard approach (30 compressions with two face-mask ventilations) or to the experimental approach (continuous manual compressions with early insertion of an i-gel
supraglottic device to deliver asynchronous ventilations). The primary outcome will be the chest compression fraction during the first two minutes of cardiopulmonary resuscitation. Secondary outcomes will be chest compression fraction (per cycle and overall), compressions and ventilations quality, time to first shock and to first ventilation, user satisfaction, and providers' self-assessed cognitive load.
