Learning with our peers: peer-led versus instructor-led debriefing for simulated crises, a randomized controlled trial.

BACKGROUND: Although peer-assisted learning is known to be effective for reciprocal learning in medical education, it has been understudied in simulation. We aimed to assess the effectiveness of peer-led compared to instructor-led debriefing for non-technical skill development in simulated crisis scenarios. METHODS: Sixty-one undergraduate medical students were randomized into the control group (instructor-led debriefing) or an intervention group (peer debriefer or peer debriefee group). After the pre-test simulation, the participants underwent two more simulation scenarios, each followed by a debriefing session. After the second debriefing session, the participants underwent an immediate post-test simulation on the same day and a retention post-test simulation two months later. Non-technical skills for the pre-test, immediate post-test, and retention tests were assessed by two blinded raters using the Ottawa Global Rating Scale (OGRS). RESULTS: The participants' non-technical skill performance significantly improved in all groups from the pre-test to the immediate post-test, with changes in the OGRS scores of 15.0 (95% CI [11.4, 18.7]) in the instructor-led group, 15.3 (11.5, 19.0) in the peer-debriefer group, and 17.6 (13.9, 21.4) in the peer-debriefee group. No significant differences in performance were found, after adjusting for the year of medical school training, among debriefing modalities (P = 0.147) or between the immediate post-test and retention test (P = 0.358). CONCLUSIONS: Peer-led debriefing was as effective as instructor-led debriefing at improving undergraduate medical students' non-technical skill performance in simulated crisis situations. Peer debriefers also improved their simulated clinical skills. The peer debriefing model is a feasible alternative to the traditional, costlier instructor model.

Efficacy of searching in biomedical databases beyond MEDLINE in identifying randomised controlled trials on hyperbaric oxygen treatment.

Introduction: Literature searches are routinely used by researchers for conducting systematic reviews as well as by healthcare providers, and sometimes patients, to quickly guide their clinical decisions. Using more than one database is generally recommended but may not always be necessary for some fields. This study aimed to determine the added value of searching additional databases beyond MEDLINE when conducting a literature search of hyperbaric oxygen treatment (HBOT) randomised controlled trials (RCTs). Methods: This study consisted of two phases: a scoping review of all RCTs in the field of HBOT, followed by a a statistical analysis of sensitivity, precision, 'number needed to read' (NNR) and 'number unique' included by individual biomedical databases. MEDLINE, Embase, Cochrane Central Register of Control Trials (CENTRAL), and Cumulated Index to Nursing and Allied Health Literature (CINAHL) were searched without date or language restrictions up to December 31, 2022. Screening and data extraction were conducted in duplicate by pairs of independent reviewers. RCTs were included if they involved human subjects and HBOT was offered either on its own or in combination with other treatments. Results: Out of 5,840 different citations identified, 367 were included for analysis. CENTRAL was the most sensitive (87.2%) and had the most unique references (7.1%). MEDLINE had the highest precision (23.8%) and optimal NNR (four). Among included references, 14.2% were unique to a single database. Conclusions: Systematic reviews of RCTs in HBOT should always utilise multiple databases, which at minimum include MEDLINE, Embase, CENTRAL and CINAHL.

Role of Oxygen and Its Radicals in Peripheral Nerve Regeneration: From Hypoxia to Physoxia to Hyperoxia.

Oxygen is compulsory for mitochondrial function and energy supply, but it has numerous more nuanced roles. The different roles of oxygen in peripheral nerve regeneration range from energy supply, inflammation, phagocytosis, and oxidative cell destruction in the context of reperfusion injury to crucial redox signaling cascades that are necessary for effective axonal outgrowth. A fine balance between reactive oxygen species production and antioxidant activity draws the line between physiological and pathological nerve regeneration. There is compelling evidence that redox signaling mediated by the Nox family of nicotinamide adenine dinucleotide phosphate (NADPH) oxidases plays an important role in peripheral nerve regeneration. Further research is needed to better characterize the role of Nox in physiological and pathological circumstances, but the available data suggest that the modulation of Nox activity fosters great therapeutic potential. One of the promising approaches to enhance nerve regeneration by modulating the redox environment is hyperbaric oxygen therapy. In this review, we highlight the influence of various oxygenation states, i.e., hypoxia, physoxia, and hyperoxia, on peripheral nerve repair and regeneration. We summarize the currently available data and knowledge on the effectiveness of using hyperbaric oxygen therapy to treat nerve injuries and discuss future directions.

Rethinking cervical spine clearance in obtunded trauma patients: An updated systematic review and meta-analysis.

BACKGROUND: Cervical spine injuries (CSI) are often challenging to diagnose in obtunded adult patients with blunt trauma and the optimal imaging modality remains uncertain. This study systematically synthesized the last decade of evidence to determine the type of imaging required to clear the c-spine in obtunded patients with blunt trauma. METHODS: A systematic review with meta-analysis was conducted and reported using PRISMA 2020 guidelines. The protocol was registered on June 22, 2022 (PROSPERO CRD42022341386). MEDLINE (Ovid), EMBASE, and Cochrane Library were searched for studies published between January 1, 2012, and October 17, 2023. Studies comparing CT alone to CT combined with MRI for c-spine clearance were included. Two independent reviewers screened articles for eligibility in duplicate. Meta-analysis was conducted using a random-effect model. Risk of bias and quality assessment were performed using the ROBINS-I and QUADAS-2. The certainty of evidence was assessed using the GRADE methodology. RESULTS: 744 obtunded trauma patients from six included studies were included. Among the 584 that had a negative CT scan, the pooled missed rate of clinically significant CSI using CT scans alone was 6 % (95 % CI: 0.02 to 0.17), and the pooled missed rate of CSI requiring treatment was 7 % (95 % CI: 0.02 to 0.18). High heterogeneity was observed among included studies (I² > 84 %). The overall risk of bias was moderate, and the quality of evidence was low due to the retrospective nature of the included studies and high heterogeneity. CONCLUSIONS: Limited evidence published in the last decade found that CT scans alone may not be sufficient for detecting clinically significant CSI and injuries requiring treatment in obtunded adult patients with blunt trauma. IMPLICATIONS OF KEY FINDINGS: Clinicians should be aware of the limitations of CT scans and consider using MRI when appropriate. Future research should focus on prospective studies with standardized outcome measures and uniform reporting.

Age and its impact on crisis management performance and learning after simulation-based education by acute care physicians: a multicentre prospective cohort study.

BACKGROUND: Physiological changes associated with ageing could negatively impact the crisis resource management skills of acute care physicians. This study was designed to determine whether physician age impacts crisis resource management skills, and crisis resource management skills learning and retention using full-body manikin simulation training in acute care physicians. METHODS: Acute care physicians at two Canadian universities participated in three 8-min simulated crisis (pulseless electrical activity) scenarios. An initial crisis scenario (pre-test) was followed by debriefing with a trained facilitator and a second crisis scenario (immediate post-test). Participants returned for a third crisis scenario 3-6 months later (retention post-test). RESULTS: For the 48 participants included in the final analysis, age negatively correlated with baseline Global Rating Scale (GRS; r=-0.30, P<0.05) and technical checklist scores (r=-0.44, P<0.01). However, only years in practice and prior simulation experience, but not age, were significant in a subsequent stepwise regression analysis. Learning from simulation-based education was shown with a mean difference in scores from pre-test to immediate post-test of 2.28 for GRS score (P<0.001) and 1.69 for technical checklist correct score (P<0.001); learning was retained for 3-6 months. Only prior simulation experience was significantly correlated with a decreased change in learning (r=-0.30, P<0.05). CONCLUSIONS: A reduced amount of prior simulation training and increased years in practice, but not age on its own, were significant predictors of low baseline crisis resource management performance. Simulation-based education leads to crisis resource management learning that is well retained for 3-6 months, regardless of age or years in practice.

Association Between Surgeon/Anesthesiologist Sex Discordance and 1-year Mortality Among Adults Undergoing Noncardiac Surgery: A Population-based Retrospective Cohort Study.

OBJECTIVE: To investigate the association between surgeon-anesthesiologist sex discordance and patient mortality after noncardiac surgery. BACKGROUND: Evidence suggests different practice patterns exist among female and male physicians. However, the influence of physician sex on team-based practices in the operating room and subsequent patient outcomes remains unclear in the context of noncardiac surgery. METHODS: We conducted a population-based, retrospective cohort study of adult Ontario residents who underwent index, inpatient noncardiac surgery between January 2007 and December 2017. The primary exposure was physician sex discordance (ie, the surgeon and anesthesiologist were of the opposite sex). The primary outcome was 1-year mortality. The association between physician sex discordance and patient outcomes was modeled using multivariable Cox proportional hazard regression with adjustment for relevant physician, patient, and hospital characteristics. RESULTS: Of 541,209 patients, 158,084 (29.2%) were treated by sex-discordant physician teams. Physician sex discordance was associated with a lower rate of mortality at 1 year [5.2% vs. 5.7%; adjusted HR: 0.95 (0.91-0.99)]. Patients treated by teams composed of female surgeons and male anesthesiologists were more likely to be alive at 1 year than those treated by all-male physician teams [adjusted HR: 0.90 (0.81-0.99)]. CONCLUSIONS: Noncardiac surgery patients had a lower likelihood of 1-year mortality when treated by sex-discordant surgeon-anesthesiologist teams. The likelihood of mortality was further reduced if the surgeon was female. Further research is needed to explore the underlying mechanisms of these observations and design strategies to diversify operating room teams to optimize performance and patient outcomes.

Impact of Unexpected Death in a Simulation Scenario on Skill Retention, Stress, and Emotions: A Simulation-Based Randomized Controlled Trial.

Introduction The simulation of patient death remains controversial in simulation-based education. We investigated the effect of simulated patient death on learners' skill retention, stress levels, and emotions. Methods After ethics approval, we recruited residents at two Canadian universities. Participants were randomized to manage a simulated cardiac arrest ending with either the unexpected death (intervention group) or survival (control group) of the simulated patient (i.e., manikin). Three months later, all participants performed the same scenario but with the opposite outcome. Blinded video raters assessed participants' non-technical and technical crisis resource management (CRM) skills at both time points. Stress levels (represented by anxiety level, salivary cortisol concentration, and cognitive appraisal) and emotional valence were measured. Outcomes were analyzed using analysis of covariance (ANCOVA) or generalized estimating equations as appropriate. Results The analysis included 46 participants (intervention: n=24; control: n=22). Simulated death neither affected retention of non-technical CRM skills (mean retention Ottawa Global Rating Scale score in the death group [29.4, 95% CI: 27.0, 31.8] versus control group [29.4, 95% CI: 26.8, 32.0; p=0.87]) nor technical CRM skills (mean retention task-specific checklist score in the manikin death group [11.8, 95% CI: 10.5, 13.0] versus the control group [12.5, 95% CI: 11.3, 13.7; p=0.69]). The simulated death had negative effects on participants' anxiety levels, cognitive appraisal, and emotions. Conclusion Simulated patient death did not affect the retention of non-technical or technical CRM skills but led to greater levels of short-term anxiety, stress, and negative emotions among learners.

The timing of booster sessions may not improve resuscitation skill retention among healthcare providers: a randomized controlled trial.

Introduction: Booster sessions can improve cardiopulmonary resuscitation (CPR) skill retention among healthcare providers; however, the optimal timing of these sessions is unknown. This study aimed to explore differences in skill retention based on booster session timing. Methods: After ethics approval, healthcare providers who completed an initial CPR training course were randomly assigned to either an early booster, late booster, or no booster group. Participants' mean resuscitation scores, time to initiate compressions, and time to successfully provide defibrillation were assessed immediately post-course and four months later using linear mixed models. Results: Seventy-three healthcare professionals were included in the analysis. There were no significant differences by randomization in the immediate post-test (9.7, 9.2, 8.9) or retention test (10.2, 9.8, and 9.5) resuscitation scores. No significant effects were observed for time to compression. Post-test time to defibrillation (mean ± SE: 112.8 ± 3.0 sec) was significantly faster compared to retention (mean ± SE: 120.4 ± 2.7 sec) (p = 0.04); however, the effect did not vary by randomization. Conclusion: No difference was observed in resuscitation skill retention between the early, late, and no booster groups. More research is needed to determine the aspects of a booster session beyond timing that contribute to skill retention.

Introduction: Des séances de rappel peuvent favoriser le maintien des compétences en réanimation cardio-pulmonaire (RCP) chez les professionnels de la santé; toutefois, le moment optimal pour offrir ces séances est inconnu. Cette étude visait à explorer les différences dans le maintien des compétences en fonction du moment où intervient la séance de rappel. Méthodes: Après avoir obtenu une approbation éthique, nous avons réparti au hasard des professionnels de la santé ayant suivi une formation initiale en RCP entre un groupe qui a reçu un rappel précoce, un groupe qui a eu un rappel tardif et un groupe qui n'a pas reçu de séance de rappel. Les scores moyens de réussite de la réanimation, le temps moyen pris avant de commencer les compressions et le temps moyen pris pour effectuer avec succès une défibrillation ont été évalués immédiatement après la séance et quatre mois plus tard, à l'aide de modèles mixtes linéaires. Résultats: Les données de 73 professionnels de la santé ont été analysées. Il n'y a pas eu de différences significatives à la suite de la randomisation dans les scores de réanimation au post-test immédiat (9,7; 9,2; 8,9) et au test sur le maintien des compétences (10,2; 9,8 et 9,5). Aucun effet significatif n'a été observé en lien avec le délai avant d'entamer les compressions. Le délai de défibrillation était significativement plus court après la séance (moyenne ± SE : 112,8 ± 3,0 sec) que lors du test de maintien des compétences (moyenne ± SE : 120,4 ± 2,7 sec) (p=0,04); cependant, l'effet n'a pas été différent d'un groupe à un autre. Conclusion: Aucune différence n'a été observée sur le plan du maintien des compétences en réanimation entre les groupes avec rappel précoce, avec rappel tardif et sans rappel. De plus amples travaux sont nécessaires pour déterminer les caractéristiques d'une séance de rappel, autres que le moment où elle intervient, qui contribueraient au maintien des compétences.

[Empowering yourself to better participate in feedback: a new cognitive-behavioural model for medical learners]. / S'outiller pour mieux participer à la rétroaction : Un nouveau modèle cognitivo-comportemental destiné aux apprenants en médecine.

Sharing formative feedback is inherent in the supervision process and the acceptance of feedback by learners is an essential step in learning. However, receiving feedback from the supervisor evokes emotions and accepting it is not easy. Several recommendations guide preceptors on how to share feedback with learners and all emphasize the importance of encouraging the learner to actively interact in the feedback process. Although studies point to the positive effect of informing and training learners about feedback, few focus on their responsiveness to feedback. Under the rubric of developing a personal skill to better accept feedback, we propose a new behavioral model, called H.O.S.T., which aims to guide learners to approach feedback with a personal growth mindset associated with the learning position. Specifically, the model presents an interdependent set of attitudes and behaviors that aim to facilitate emotional management and engagement in the feedback process, in order to initiate the reflective process necessary for learning and to enable the acquisition of targeted skills. The acronym H.O.S.T. reminds students of the four essential elements of the behavioral model: humility, openness, shared explicitness and tenacity. Based on the positive psychology movement, each element is defined and justified by known theoretical concepts. In order to better assimilate the components of the model, the use of internal dialogue is adopted to facilitate the training and adoption of behaviors. The essence of the model is discussed in light of the feedback literacy dedicated to learners.

Hyperbaric medicine in Canadian undergraduate medical school curriculum.

INTRODUCTION: Hyperbaric oxygen treatment (HBOT) has fourteen approved indications in the management of acute and chronic diseases in various medical specialties. However, lack of physician knowledge and exposure to hyperbaric medicine may hinder the ability of patients to access this treatment option for approved indications. We aimed to determine the prevalence and nature of HBOT-related learning objectives in Canadian undergraduate medical education programs. METHODS: Pre-clerkship and clerkship learning objectives from responding Canadian medical schools' curricula were reviewed. These were acquired through the school websites or by emailing the faculties. Descriptive statistics were used to summarise the number of hyperbaric medicine objectives taught in Canadian medical schools, and within each institution. RESULTS: Learning objectives from seven of the 17 Canadian medical schools were received and reviewed. From the curriculum of the responding schools, only one objective was found to be related to hyperbaric medicine. Hyperbaric medicine was absent from the other six schools' objectives. CONCLUSIONS: Based on the responding Canadian medical schools, hyperbaric medicine objectives were mostly absent from undergraduate medical curricula. These findings illustrate a possible gap in HBOT education and the need for discussion regarding the design and implementation of HBOT educational initiatives in medical training.

Professional Coaching as a Continuing Professional Development Intervention to Address the Physician Distress Epidemic.

ABSTRACT: Physician distress and burnout are reaching epidemic proportions, threatening physicians' capacities to develop and maintain competencies in the face of the increasingly demanding and complex realities of medical practice in today's world. In this article, we suggest that coaching should be considered both a continuing professional development intervention as well as an integral part of a balanced and proactive solution to physician distress and burnout. Unlike other interventions, coaching is intended to help individuals gain clarity in their life, rather than to treat a mental health condition or to provide advice, support, guidance, or knowledge/skills. Certified coaches are trained to help individuals discover solutions to complex problems and facilitate decision-making about what is needed to build and maintain capacity and take action. Across many sectors, coaching has been shown to enhance performance and reduce vulnerability to distress and burnout, but it has yet to be systematically implemented in medicine. By empowering physicians to discover and implement solutions to challenges, regain control over their lives, and act according to their own values, coaching can position physicians to become leaders and advocates for system-level change, while simultaneously prioritizing their own well-being.

Identifying positive and negative use of non-technical skills by anesthesiologists in the clinical operating room: An exploratory descriptive study.

Background: Teamwork is a critical competency in high-risk settings like the operating room (OR). While conventional approaches focus on describing and learning from negative performance, there may be value in learning from high-performing behaviour, particularly in specialties where serious safety events are relatively rare. This study aimed to explore both the positive and negative use of non-technical skills by anesthesia practitioners in the OR and situate them within the clinical OR context. Methods: This study employed a prospective observational design. Following research ethics approval, a sample of surgical cases in a tertiary hospital were recorded using the OR Black Box®. Data related to surgical phase timing, non-technical skills, team factors, and environmental factors were identified by analysts according to a modified Systems Engineering Initiative for Patient Safety model. We performed descriptive statistics and qualitative description of these observations. Results: We observed 25 surgical cases capturing 242 instances of positive non-technical skills among anesthesiologists in the operating room and 9 instances of negative demonstrations. Situational awareness was most frequently (n = 160) observed, followed by communication and teamwork skills (n = 82), and were most often demonstrated in the context of potential environmental distractions (e.g., doors opening, unnecessary interruptions). The least common category of positive non-technical skills observed was leadership (n = 3). Conclusions: Our findings show anesthesiologists are doing a lot "right" and there may be many opportunities for learning from positive practice in the clinical setting. These findings can inform future work to better understand and standardize best practices for non-technical performance in anesthesia.

Impact of coaching on physician wellness: A systematic review.

Physician wellness is critical for patient safety and quality of care. Coaching has been successfully and widely applied across many industries to enhance well-being but has only recently been considered for physicians. This review aimed to summarize the existing evidence on the effect of coaching by trained coaches on physician well-being, distress and burnout. MEDLINE, Embase, ERIC, PsycINFO and Web of Science were searched without language restrictions to December 21, 2022. Studies of any design were included if they involved physicians of any specialty undergoing coaching by trained coaches and assessed at least one measure along the wellness continuum. Pairs of independent reviewers determined reference eligibility. Risk of bias was assessed using the Cochrane Risk of Bias Tools for Randomized Controlled Trials (RCTs) and for Non-randomized Studies of Interventions (ROBINS-I). Meta-analysis was not possible due to heterogeneity in study design and outcome measures as well as inconsistent reporting. The search retrieved 2531 references, of which 14 were included (5 RCTs, 2 non-randomized controlled studies, 4 before-and-after studies, 2 mixed-methods studies, 1 qualitative study). There were 1099 participants across all included studies. Risk of bias was moderate or serious for non-RCTs, while the 5 RCTs were of lower risk. All quantitative studies reported effectiveness of coaching for at least one outcome assessed. The included qualitative study reported a perceived positive impact of coaching by participants. Evidence from available RCTs suggests coaching for physicians can improve well-being and reduce distress/burnout. Non-randomized interventional studies have similar findings but face many limitations. Consistent reporting and standardized outcome measures are needed.

Analyzing interprofessional teamwork in the operating room: An exploratory observational study using conventional and alternative approaches.

Intraoperative teamwork is vital for patient safety. Conventional tools for studying intraoperative teamwork typically rely on behaviorally anchored rating scales applied at the individual or team level, while others capture narrative information across several units of analysis. This prospective observational study characterizes teamwork using two conventional tools (Operating Theatre Team Non-Technical Skills Assessment Tool [NOTECHS]; Team Emergency Assessment Measure [TEAM]), and one alternative approach (modified-Systems Engineering Initiative for Patient Safety [SEIPS] model). We aimed to explore the advantages and disadvantages of each for providing feedback to improve teamwork practice. Fifty consecutive surgical cases at a Canadian academic hospital were recorded with the OR Black Box®, analyzed by trained raters, and summarized descriptively. Teamwork performance was consistently high within and across cases rated with NOTECHS and TEAMS. For cases analyzed with the modified-SEIPS tool, both optimal and suboptimal teamwork behaviors were identified, and team resilience was frequently observed. NOTECHS and TEAM provided summative assessments and overall pattern descriptions, while SEIPS facilitated a deeper understanding of teamwork processes. As healthcare organizations continue to prioritize teamwork improvement, SEIPS may provide valuable insights regarding teamwork behavior and the broader context influencing performance. This may ultimately enhance the development and effectiveness of multi-level teamwork interventions.

Effectiveness of interprofessional teamwork interventions for improving occupational well-being among perioperative healthcare providers: a systematic review.

The occupational well-being of healthcare providers is crucial for safe and effective patient care, especially in the complex, high acuity operating room (OR) setting. There has been a recent proliferation of interventions to improve teamwork in the OR setting, but the impact of these interventions on clinician occupational well-being has yet to be systematically assessed. This systematic review aimed to summarize the impact of interprofessional teamwork interventions on occupational well-being among perioperative healthcare providers. We included all qualitative or quantitative peer-reviewed studies assessing a multidisciplinary teamwork intervention including members of at least two professions. We included seven studies which involved checklists (n = 2), simulation-based training (n = 2), and various teamwork development and training programs (n = 3). Five of the seven included studies reported no significant effect on job satisfaction, while one found a significant negative association between the intervention and job satisfaction (p < .0001), and another showed significant decrease in worker stress. Our findings highlight the gaps in our understanding of the impact of interprofessional teamwork interventions on healthcare worker well-being in the perioperative environment and the multi-level factors influencing OR teamwork, intervention implementation, and well-being across the different professions.

Communicating effectively with patients about vaccination: A systematic review of randomized controlled trials.

Background: Good communication between healthcare professionals and their patients is essential to enlighten the benefits and risks of vaccination. Despite the availability of effective vaccines, reluctance prevails, sometimes fuelled by sub-optimal communication leading to a lack of trust. An evaluation of the effectiveness of a communication strategy for which healthcare professionals are trained has yet to be carried out. Objective: Systematic review of studies with a randomized controlled trial (RCT) to define and evaluate the impact of healthcare professionals' communication on patients' vaccine adherence. Methods: We performed a structured search on Medline, Embase, CENTRAL, PsycINFO and CINAHL. The studies selected include those involving healthcare professionals authorized to administer vaccines according to Canadian guidelines. Primary outcomes include vaccination rate or vaccine hesitancy rate. Results: Nine articles were included. Five studies (n=5) reported intervention effectiveness according to vaccine adherence. The results are largely represented by parental vaccine hesitancy for human papillomavirus (HPV) or childhood vaccination, while three studies (n=3) target the general population. The risk of bias relative to the studies is either low (n=7) or of some concern (n=2). Conclusion: The effectiveness of communication varies according to the studies and knowledge acquired through training. Future studies will need to examine communication with healthcare professionals in order to establish a consensus on optimal and appropriate training.

Portrait of French-speaking minorities with respect to vaccination against COVID-19.

Background: The coronavirus disease 2019 (COVID-19) vaccination campaign highlighted the requirement to better understand the needs of different populations. French-speaking minorities (FSMs) have greater difficulty accessing quality care in French, and this problem was exacerbated during the COVID-19 pandemic. Objective: The aim of this survey was to develop a descriptive portrait of the health needs of FSMs in relation to the COVID-19 vaccination campaign by describing their vaccination status, attitudes and beliefs compared with English-speaking majorities. Methods: A survey was conducted among eligible participants using convenience sampling. Data measurement includes a descriptive statistical comparison using analysis of the variance, univariate logistic regressions and a two-proportions z-test. Results: Of the 1,505 respondents (554 FSMs vs. 951 English speakers), the FSMs have an average age of 51.4 years and 89.2% are Canadian citizens. Vaccination of children was preponderant among English speakers (74.2% vs. 86.3%), including against COVID-19 (58.6% vs. 73.9%). A higher proportion of FSMs had gotten vaccinated in order to obtain a vaccine passport (39% vs. 29.3%). Among the unvaccinated, FSMs were more likely to question the efficacy of vaccines (60% vs. 36.4%). Canadian citizen FSMs with higher education could be divided in relation to the vaccine regimen. Conclusion: This survey revealed differences between FSMs and the English-speaking majority in their perceptions of vaccine efficacy, particularly vaccination of children, and a polarization of attitudes/beliefs among FSMs according to certain sociodemographic factors.

Simulation-based summative assessment in healthcare: an overview of key principles for practice.

BACKGROUND: Healthcare curricula need summative assessments relevant to and representative of clinical situations to best select and train learners. Simulation provides multiple benefits with a growing literature base proving its utility for training in a formative context. Advancing to the next step, "the use of simulation for summative assessment" requires rigorous and evidence-based development because any summative assessment is high stakes for participants, trainers, and programs. The first step of this process is to identify the baseline from which we can start. METHODS: First, using a modified nominal group technique, a task force of 34 panelists defined topics to clarify the why, how, what, when, and who for using simulation-based summative assessment (SBSA). Second, each topic was explored by a group of panelists based on state-of-the-art literature reviews technique with a snowball method to identify further references. Our goal was to identify current knowledge and potential recommendations for future directions. Results were cross-checked among groups and reviewed by an independent expert committee. RESULTS: Seven topics were selected by the task force: "What can be assessed in simulation?", "Assessment tools for SBSA", "Consequences of undergoing the SBSA process", "Scenarios for SBSA", "Debriefing, video, and research for SBSA", "Trainers for SBSA", and "Implementation of SBSA in healthcare". Together, these seven explorations provide an overview of what is known and can be done with relative certainty, and what is unknown and probably needs further investigation. Based on this work, we highlighted the trustworthiness of different summative assessment-related conclusions, the remaining important problems and questions, and their consequences for participants and institutions of how SBSA is conducted. CONCLUSION: Our results identified among the seven topics one area with robust evidence in the literature ("What can be assessed in simulation?"), three areas with evidence that require guidance by expert opinion ("Assessment tools for SBSA", "Scenarios for SBSA", "Implementation of SBSA in healthcare"), and three areas with weak or emerging evidence ("Consequences of undergoing the SBSA process", "Debriefing for SBSA", "Trainers for SBSA"). Using SBSA holds much promise, with increasing demand for this application. Due to the important stakes involved, it must be rigorously conducted and supervised. Guidelines for good practice should be formalized to help with conduct and implementation. We believe this baseline can direct future investigation and the development of guidelines.

Hyperbaric oxygen therapy for treatment of a late presenting ischaemic complication from hyaluronic acid cosmetic filler injection.

Vascular compromise and resulting ischaemic injury are known rare complications of cosmetic filler injections. Most hyaluronic acid vascular compromises present early and can be treated effectively by hyaluronidase. Here we present a case of ischaemic wound and mucosal necrosis after cosmetic facial hyaluronic acid injection that appeared within hours of injection but was not diagnosed and treated for 5 days. At day 5, the patient was treated with hyaluronidase injection immediately followed by 14 sessions of daily hyperbaric oxygen therapy (HBOT). Despite the delayed treatment, the patient had essentially complete recovery and the hyperbaric therapy was overall well-tolerated. Our case report suggests that hyaluronidase injection with concurrent daily HBOT sessions may be effective to allow recovery from late-presenting filler ischaemic complication. Furthermore, given the safety profile of HBOT, we suggest a more deliberate approach to this modality as a therapeutic adjunct by cosmetic practitioners when similar complications arise.
