Women at the top: a qualitative study of women in leadership positions in emergency medicine in Canada.

OBJECTIVES: For the last two decades, more than half of Canadian medical students have been women, with an increasing number of medical trainees choosing emergency medicine as their careers. Despite a proportional increase of women in full-time faculty positions in emergency medicine, women are still underrepresented in leadership. The purpose of this study is to explore the experiences of women leaders in emergency medicine to identify common themes that may have contributed to their acquisition of leadership roles. METHODS: Participants included women emergency medicine physicians in Canada who currently or previously held a leadership position. Data were collected through semi-structured interviews. Inductive thematic analysis was performed on the interview transcripts. Transcribed data were coded and categorized into recurrent themes. A narrative summary of the most impactful themes was presented. RESULTS: Twenty participants were interviewed. Most participants perceived career opportunities were due to chance, related to personal skill set, or required additional training. Participants highlighted the importance of mentorship and sponsorship. Gender expectations and traditional gender roles were perceived as having a negative impact on career leadership success. Participants acknowledged the need for women in leadership to empower younger generations of women to become leaders. For future emergency medicine leaders, participants suggested applying for leadership positions early, networking, and seeking mentorship. Potential supportive changes to leadership structures included explicit parental leave policies, flexible scheduling, and job sharing to encourage women leaders. CONCLUSION: To date, there has been no Canadian specific study exploring the factors contributing to the success of women leaders in emergency medicine. This study examines career advancement of women leaders in emergency medicine and provides useful insight to those aspiring to grow their careers, as well as to mentors and sponsors of women in emergency medicine.

RéSUMé: OBJECTIFS: Au cours des deux dernières décennies, plus de la moitié des étudiants en médecine canadiens étaient des femmes, et un nombre croissant de stagiaires en médecine ont choisi la médecine d'urgence comme carrière. Malgré une augmentation proportionnelle du nombre de femmes occupant des postes de professeurs à temps plein en médecine d'urgence, les femmes sont encore sous-représentées dans les postes de direction. Le but de cette étude est d'explorer les expériences des femmes leaders en médecine d'urgence pour identifier les thèmes communs qui peuvent avoir contribué à leur acquisition de rôles de leadership. MéTHODES: Parmi les participantes figuraient des femmes médecins d'urgence au Canada qui occupaient actuellement ou auparavant un poste de direction. Les données ont été recueillies au moyen d'entrevues semi-structurées. Une analyse thématique inductive a été effectuée sur les transcriptions des entrevues. Les données transcrites ont été codées et classées en thèmes récurrents. Un résumé narratif des thèmes les plus percutants a été présenté. RéSULTATS: Vingt participants ont été interrogés. La plupart des participants estimaient que les possibilités de carrière étaient attribuables au hasard, à des compétences personnelles ou à une formation supplémentaire. Les participants ont souligné l'importance du mentorat et du parrainage. Les attentes en matière de genre et les rôles traditionnels de genre ont été perçus comme ayant un impact négatif sur le succès de leadership de carrière. Les participants ont reconnu la nécessité pour les femmes dirigeantes de permettre aux jeunes générations de femmes de devenir des leaders. Pour les futurs dirigeants en médecine d'urgence, les participants ont suggéré de postuler tôt pour des postes de leadership, de réseauter et de chercher du mentorat. Parmi les changements favorables possibles aux structures de direction, mentionnons des politiques de congé parental explicites, des horaires souples et le partage d'emploi pour encourager les dirigeantes. CONCLUSION: À ce jour, aucune étude canadienne n'a exploré les facteurs qui contribuent au succès des femmes chefs de file en médecine d'urgence. Cette étude examine l'avancement professionnel des femmes chefs de file en médecine d'urgence et fournit des renseignements utiles aux personnes qui aspirent à faire progresser leur carrière, ainsi qu'aux mentors et aux parrains des femmes en médecine d'urgence.

COVID-19 vaccine reactogenicity among participants enrolled in the GENCOV study.

BACKGROUND: GENCOV is a prospective, observational cohort study of COVID-19-positive adults. Here, we characterize and compare side effects between COVID-19 vaccines and determine whether reactogenicity is exacerbated by prior SARS-CoV-2 infection. METHODS: Participants were recruited across Ontario, Canada. Participant-reported demographic and COVID-19 vaccination data were collected using a questionnaire. Multivariable logistic regression was performed to assess whether vaccine manufacturer, type, and previous SARS-CoV-2 infection are associated with reactogenicity. RESULTS: Responses were obtained from n = 554 participants. Tiredness and localized side effects were the most common reactions across vaccine doses. For most participants, side effects occurred and subsided within 1-2 days. Recipients of Moderna mRNA and AstraZeneca vector vaccines reported reactions more frequently compared to recipients of a Pfizer-BioNTech mRNA vaccine. Previous SARS-CoV-2 infection was independently associated with developing side effects. CONCLUSIONS: We provide evidence of relatively mild and short-lived reactions reported by participants who have received approved COVID-19 vaccines.

A comparison of minimum segment models for the estimation of centre of mass position and velocity for slip recovery during a bathtub transfer task.

BACKGROUND: Exploring the use of minimum marker sets is important for balancing the technical quality of motion capture with challenging data collection environments and protocols. While minimum marker sets have been demonstrated to be appropriate for evaluation of some motion patterns, there is limited evidence to support model choices for abrupt, asymmetrical, non-cyclic motion such as balance disturbance during a bathtub exit task. RESEARCH QUESTION: How effective are six models of reduced complexity for the estimation of centre of mass (COM) displacement and velocity, relative to a full-body model. METHODS: Eight participants completed a bathtub exit task. Participants received a balance perturbation as they crossed the bathtub rim, stepping from a soapy wet bathtub to a dry floor. Six reduced models were developed from the full, 72-marker, 12 segment 3D kinematic data set. Peak displacement and velocity of the body COM, and RMSE (relative to the full-body model) for displacement and velocity of the body COM were determined for each model. RESULTS: Main effects were observed for peak right, left, anterior, posterior, upwards and downwards motion, and peak left, anterior, posterior, upwards and downwards velocity. Time-varying (RMSE) was smaller for models including the thighs than models not containing the thighs. In contrast, inclusion of upper arm, forearm, and hand segments did not improve model performance. The model containing the sacrum marker only consistently performed the worst across peak and RMSE metrics. SIGNIFICANCE: Findings suggest a simplified centre of mass model may adequately capture abrupt, asymmetrical, non-cyclic tasks, such as balance disturbance recovery during obstacle crossing. A reduced kinematic model should include the thighs, trunk and pelvis segments, although models that are more complex are recommended, depending on the metrics of interest.

Experiences of healthcare providers with a novel emergency response intubation team during COVID-19.

OBJECTIVES: In the early stages of the COVID-19 pandemic, there were significant concerns about the infectious risks of intubation to healthcare providers. In response, a dedicated emergency response intubation team (ERIT) consisting of anesthesiologists and allied health providers was instituted for our emergency department (ED). Given the high-risk nature of intubations and the new interprofessional team dynamics, we sought to assess health-care provider experiences and potential areas of improvement. METHODS: Surveys were distributed to healthcare providers at the University Health Network, a quaternary healthcare centre in Toronto, Canada, which includes two urban EDs seeing over 128,000 patients per year. Participants included ED physicians and nurses, anesthesiologists, anesthesia assistants, and operating room nurses. The survey included free-text questions. Responses underwent thematic analysis using grounded theory and were independently coded by two authors to generate descriptive themes. Discrepancies were resolved with a third author. Descriptive themes were distilled through an inductive, iterative process until fewer main themes emerged. RESULTS: A total of 178 surveys were collected (68.2% response rate). Of these, 123 (69%) participated in one or more ERIT activations. Positive aspects included increased numbers of staff to assist, increased intubation expertise, improved safety, and good team dynamics within the ERIT team. Challenges included a loss of scope (primarily ED physicians and nurses) and unfamiliar workflows, perceived delays to ERIT team arrival or patient intubation, role confusion, handover concerns, and communication challenges between ED and ERIT teams. Perceived opportunities for improvement included interprofessional training, developing clear guidelines on activation, inter-team role clarification, and guidelines on handover processes post-intubation. CONCLUSIONS: Healthcare providers perceived that a novel interprofessional collaboration for intubations of COVID-19 patients presented both benefits and challenges. Opportunities for improvement centred around interprofessional training, shared decision making between teams, and structured handoff processes.

RéSUMé: OBJECTIFS: Aux premiers stades de la pandémie de COVID-19, les risques infectieux de l'intubation pour les prestataires de soins de santé ont suscité de vives inquiétudes. En réponse, une équipe d'intervention d'urgence en intubation (emergency response intubation team ERIT), composée d'anesthésistes et de prestataires de services paramédicaux, a été mise en place dans notre service d'urgence. Compte tenu de la nature à haut risque des intubations et de la nouvelle dynamique d'équipe interprofessionnelle, nous avons cherché à évaluer les expériences des prestataires de soins et les domaines d'amélioration potentiels. MéTHODES: Les questionnaires ont été distribués aux prestataires de soins de santé du University Health Network, un centre de soins de santé quaternaire de Toronto, au Canada, qui comprend deux urgences urbaines accueillant plus de 128 000 patients par an. Les participants comprenaient des médecins et des infirmiers des urgences, des anesthésistes, des assistants en anesthésie et des infirmiers de salle d'opération. Les réponses ont fait l'objet d'une analyse thématique fondée sur la théorie de la base et ont été codées indépendamment par deux auteurs afin de générer des thèmes descriptifs. Les divergences ont été résolues avec un troisième auteur. Les thèmes descriptifs ont été distillés par un processus inductif et itératif jusqu'à ce qu'un nombre réduit de thèmes principaux émerge. RéSULTATS: Au total, 178 sondages ont été recueillis (taux de réponse de 68,2 %). Parmi ceux-ci, 123 (69 %) ont participé à une ou plusieurs activations d'ERIT. Les aspects positifs comprenaient un nombre accru de personnel pour aider, une expertise accrue en matière d'intubation, une sécurité améliorée et une bonne dynamique d'équipe au sein de l'équipe ERIT. Parmi les difficultés rencontrées, citons la perte du champ d'action (principalement les médecins et les infirmières des services d'urgence) et les flux de travail non familiers, les retards perçus dans l'arrivée de l'équipe d'ERIT ou l'intubation du patient, la confusion des rôles, les problèmes de transfert et les difficultés de communication entre les équipes des services d'urgence et d'ERIT. Les possibilités d'amélioration perçues comprennent la formation interprofessionnelle, l'élaboration de directives claires sur l'activation, la clarification des rôles entre les équipes et les directives sur les processus de transfert après l'intubation. CONCLUSIONS: Les prestataires de soins de santé ont perçu qu'une nouvelle collaboration interprofessionnelle pour les intubations des patients COVID-19 présentait à la fois des avantages et des défis.

Use of handrails for balance and stability: Characterizing loading profiles in younger adults.

Well-designed handrails significantly enhance balance recovery, by allowing users to apply high forces to the rail and stabilize their center of mass. However, data on user-applied handrail forces during balance recovery are limited. We characterized the peak forces that 50 young adults applied to a handrail during forward and backward falling motions; quantified effects of handrail height (34, 38, 42 inches) and position prior to balance loss (standing beside the rail with or without hand contact, or facing the handrail with two-handed contact); and examined the relationship between handrail forces and individual mass. The testing environment consisted of a robotic platform that translated rapidly to destabilize participants, and a height-adjustable handrail that was mounted to the platform. Our findings support our hypotheses that starting position and handrail height significantly affect peak handrail forces in most axes. The highest handrail forces were applied when participants faced the handrail and grasped with two hands. In these cases, increased handrail height was associated with increased anterior forces and decreased downward, upward and resultant forces. As hypothesized, peak handrail forces correlated strongly with individual weight in most axes. Implications of these findings for handrail design are discussed.

Influence of handrail height and fall direction on center of mass control and the physical demands of reach-to-grasp balance recovery reactions.

The ability to maintain and recover center of mass (COM) and trunk control after a destabilization is critical for avoiding falls and fall-related injuries. Handrails can significantly enhance a person's ability to recover from large destabilizations, by enabling the person to grasp and apply high forces to the rail to stabilize their COM. However, the influence of handrail height and falling direction on COM control and the demands of grasping are unknown. We investigated the effect of handrail height (34, 38, 42 in.) and fall direction (forward, backward) on COM and trunk control, and the corresponding physical demands of reach-to-grasp balance reactions. Thirteen young adults were destabilized with platform perturbations, and reached to grasp a nearby handrail to recover balance without stepping. COM kinematics and applied handrail forces were collected. COM control was evaluated in terms of: (1) COM range and peak displacement, velocity and momentum in all Cartesian axes; and (2) trunk angular displacement, velocity and momentum in the roll and pitch axes. The physical demands of grasping were estimated via resultant handrail impulse. Compared to forward-directed falling, backward-directed falling was generally associated with greater peak COM and trunk angular displacement, velocity and momentum, along with greater handrail impulse. Higher handrails generally resulted in reduced peak COM and trunk angular displacement, velocity and momentum, as well as reduced handrail impulse. These results suggest that higher handrails may provide a stability advantage within the range of handrail heights tested, with better COM control achieved with lower physical demands of grasping.
