A relational approach to improving interprofessional teamwork in post-partum haemorrhage (PPH).

BACKGROUND: Post-partum haemorrhage (PPH) is an obstetric emergency that requires effective teamwork under complex conditions. We explored healthcare team performance for women who suffered a PPH, focusing on relationships and culture as critical influences on teamwork behaviours and outcomes. METHODS: In collaboration with clinical teams, we implemented structural, process and relational interventions to improve teamwork in PPH cases. We were guided by the conceptual framework of Relational Coordination and used a mixed methods approach to data collection and analysis. We employed translational simulation as a central, but not singular, technique for enabling exploration and improvement. Key themes were identified from surveys, focus groups, simulation sessions, interviews, and personal communications over a 12-month period. RESULTS: Four overarching themes were identified: 1) Teamwork, clear roles and identified leadership are critical. 2) Relational factors powerfully underpin teamwork behaviours-shared goals, shared knowledge, and mutual respect. 3) Conflict and poor relationships can and should be actively explored and addressed to improve performance. 4) Simulation supports improved team performance through multifaceted mechanisms. One year after the project commenced, significant progress had been made in relationships and systems. Clinical outcomes have improved; despite unprecedented increase in labour ward activity, there has not been any increase in large PPHs. CONCLUSIONS: Teamwork, relationships, and the context of care can be actively shaped in partnership with clinicians to support high performance in maternity care. We present our multifaceted approach as a guide for leaders and clinicians in maternity teams, and as an exemplar for others enacting quality improvement in healthcare.

Training disrupted: Practical tips for supporting competency-based medical education during the COVID-19 pandemic.

The COVID-19 pandemic has disrupted healthcare systems around the world, impacting how we deliver medical education. The normal day-to-day routines have been altered for a number of reasons, including changes to scheduled training rotations, physical distancing requirements, trainee redeployment, and heightened level of concern. Medical educators will likely need to adapt their programs to maximize learning, maintain effective care delivery, and ensure competent graduates. Along with a continued focus on learner/faculty wellness, medical educators will have to optimize existing training experiences, adapt those that are no longer viable, employ new technologies, and be flexible when assessing competencies. These practical tips offer guidance on how to adapt medical education programs within the constraints of the pandemic landscape, stressing the need for communication, innovation, collaboration, flexibility, and planning within the era of competency-based medical education.

Quality Evaluation Scores are no more Reliable than Gestalt in Evaluating the Quality of Emergency Medicine Blogs: A METRIQ Study.

Construct: We investigated the quality of emergency medicine (EM) blogs as educational resources. PURPOSE: Online medical education resources such as blogs are increasingly used by EM trainees and clinicians. However, quality evaluations of these resources using gestalt are unreliable. We investigated the reliability of two previously derived quality evaluation instruments for blogs. APPROACH: Sixty English-language EM websites that published clinically oriented blog posts between January 1 and February 24, 2016, were identified. A random number generator selected 10 websites, and the 2 most recent clinically oriented blog posts from each site were evaluated using gestalt, the Academic Life in Emergency Medicine (ALiEM) Approved Instructional Resources (AIR) score, and the Medical Education Translational Resources: Impact and Quality (METRIQ-8) score, by a sample of medical students, EM residents, and EM attendings. Each rater evaluated all 20 blog posts with gestalt and 15 of the 20 blog posts with the ALiEM AIR and METRIQ-8 scores. Pearson's correlations were calculated between the average scores for each metric. Single-measure intraclass correlation coefficients (ICCs) evaluated the reliability of each instrument. RESULTS: Our study included 121 medical students, 88 EM residents, and 100 EM attendings who completed ratings. The average gestalt rating of each blog post correlated strongly with the average scores for ALiEM AIR (r = .94) and METRIQ-8 (r = .91). Single-measure ICCs were fair for gestalt (0.37, IQR 0.25-0.56), ALiEM AIR (0.41, IQR 0.29-0.60) and METRIQ-8 (0.40, IQR 0.28-0.59). CONCLUSION: The average scores of each blog post correlated strongly with gestalt ratings. However, neither ALiEM AIR nor METRIQ-8 showed higher reliability than gestalt. Improved reliability may be possible through rater training and instrument refinement.

Ependymoma in children under the age of 3 years: a report from the Canadian Pediatric Brain Tumour Consortium.

The determination of optimal therapy for ependymoma (EP) in infants is ongoing. We describe the incidence, management and outcomes of Canadian infants with EP to discern potential future research questions. Of 579 cases registered in a national database of children <36 months of age diagnosed with a brain tumor from 1990 to 2005, inclusive, 75 (13 %) were EP. These cases were analyzed. A mean annual age-adjusted incidence rate of 4.6 per 100,000 children years was calculated. The male:female ratio was 1.77. Of the tumors, 80 % were infratentorial in location, 67 % were WHO grade II histology, and 29 % were metastatic at diagnosis. All patients underwent a surgical procedure. A complete resection of the tumor was achieved in 56 % of the cases; 43 % of these patients survive while 36 % of the patients with tumors less than completely resected survive. Initial therapy consisted of surgery alone in 23 % of patients, or surgery plus chemotherapy (37 %), radiation therapy (RT; 19 %), or both (21 %). Any use of RT increased with patient age. The 5-year EFS rates for patients in each of the four treatment groups was 22, 11.5, 46.2 and 64.8 %, respectively. For all patients the median survival was 63 ± 6 months and 5-year overall survival was 55 ± 6 %. Patients treated with surgery and chemotherapy alone were younger and had a lower rate of survival than older patients who were more often treated with radiation therapy containing regimens. Further study is needed to determine which patients are optimally served with these treatment modalities.

Equity, diversity and inclusion in simulation-based education: constructing a developmental framework for medical educators.

BACKGROUND: Themes of equity, diversity and inclusion (EDI) arise commonly within healthcare simulation. Though faculty development guidance and standards include increasing reference to EDI, information on how faculty might develop in this area is lacking. With increasingly formal expectations being placed on simulation educators to adhere to EDI principles, we require a better understanding of the developmental needs of educators and clear guidance so that teams can work towards these expectations. Our study had two aims: Firstly, to explore the extent to which an existing competency framework for medical teachers to teach ethnic and cultural diversity is relevant for simulation educator competency in EDI, and secondly, informed by the data gathered, to construct a modified competency framework in EDI for simulation educators. METHODS: We engaged our participants (10 simulation faculty) in a 5-month period of enhanced consideration of EDI, using the SIM-EDI tool to support faculty debriefing conversations focussed on EDI within a pre-existing programme of simulation. We interviewed participants individually at two timepoints and analysed transcript data using template analysis. We employed an existing competency framework for medical teachers as the initial coding framework. Competencies were amended for the simulation context, modified based on the data, and new themes were added inductively, to develop a new developmental framework for simulation educators. RESULTS: Interview data supported the relevance of the existing competency framework to simulation. Modifications made to the framework included the incorporation of two inductively coded themes ('team reflection on EDI' and 'collaboration'), as well as more minor amendments to better suit the healthcare simulation context. The resultant Developmental Framework for Simulation Educators in EDI outlines 10 developmental areas we feel are required to incorporate consideration of EDI into simulation programmes during the design, delivery and debriefing phases. We propose that the framework acts as a basis for simulation faculty development in EDI. CONCLUSIONS: Simulation faculty development in EDI is important and increasingly called for by advisory bodies. We present a Developmental Framework for Simulation Educators in EDI informed by qualitative data. We encourage simulation teams to incorporate this framework into faculty development programmes and report on their experiences.

The Buddy Study: Local reach, adoption and implementation following a randomised controlled trial of conservative management of fifth metacarpal neck fractures.

OBJECTIVE: To understand the reach, adoption and implementation of the evidence that buddy strapping for uncomplicated fifth metacarpal neck fractures is non-inferior to plaster casting. METHODS: Mixed-method study using clinical audit of the years before and after the original randomised controlled study was published (2019) and staff questionnaires/semi-structured interviews. RESULTS: Sixty-nine percent of questionnaire respondents were aware of the original study findings (i.e. reach) and 57% had adopted the research findings. The proportion of patients receiving buddy strapping was 6% in 2014-2016 and 28% in 2019-2021 (implementation). Qualitative data provided insight into ongoing barriers to adoption and implementation including fear of reprisal, the need for permission, opinions of senior decision makers, perceptions about patient preferences, and an overall tendency to 'play it safe'. CONCLUSIONS: Even in a department where primary research is conducted, implementation requires ongoing attention to factors impacting reach and adoption.

An Exploration of the Interplay Between Well-being and Quality and Safety.

PURPOSE: Quality improvement and patient safety (QIPS) and clinician well-being work are interconnected and impact each other. Well-being is of increased importance in the current state of workforce shortages and high levels of burnout. The Canadian Association of Emergency Physicians (CAEP) Academic Symposium sought to understand the interplay between QIPS and clinician well-being and to provide practical recommendations to clinicians and institutions on ensuring that clinician well-being is integrated into QIPS efforts. METHODS: A team of emergency physicians with expertise in well-being and QIPS performed a literature review, drafted goals and recommendations, and presented at the CAEP Academic Symposium in 2023 for feedback. Goals and recommendations were then further refined. RESULTS: Three goals and recommendations were developed as follows: QIPS leaders and practitioners must (1) understand the potential intersection of well-being and QIPS, (2) consider a well-being lens for all QIPS work, and (3) incorporate QIPS methodology in efforts to improve clinician well-being. CONCLUSION: QIPS and clinician well-being are often closely linked. By incorporating these recommendations, QIPS strategies can enhance clinician well-being.

RéSUMé: OBJECTIF: Le travail d'amélioration de la qualité et de la sécurité des patients (QIPS) et le bien-être des cliniciens sont interreliés et ont des répercussions les uns sur les autres. Le bien-être est d'une importance croissante dans l'état actuel des pénuries de main-d'œuvre et des niveaux élevés d'épuisement professionnel. Le symposium universitaire de l'Association canadienne des médecins d'urgence (ACMU) visait à comprendre l'interaction entre le SPQI et le bien-être des cliniciens et à fournir des recommandations pratiques aux cliniciens et aux établissements pour assurer le bien-être des cliniciens. . .Le programme QIPS est intégré aux efforts du QIPS. MéTHODES: Une équipe de médecins urgentistes ayant une expertise en bien-être et QIPS a effectué une revue de la littérature, rédigé des objectifs et des recommandations, et présenté au symposium académique de l'ACMU en 2023 pour obtenir une rétroaction. Les objectifs et les recommandations ont ensuite été affinés. RéSULTATS: Trois objectifs et recommandations ont été élaborés : les dirigeants et les praticiens du SPQI doivent (1) comprendre l'intersection potentielle du bien-être et du SPQI, (2) envisager une optique du bien-être pour tous les travaux du SPQI, et (3) intégrer la méthodologie QIPS dans les efforts visant à améliorer le bien-être des cliniciens. CONCLUSIONS: Le SPQI et le bien-être des cliniciens sont souvent étroitement liés. En intégrant ces recommandations, les stratégies QIPS peuvent améliorer le bien-être des cliniciens.

Early cisplatin induced ototoxicity profile may predict the need for hearing support in children with medulloblastoma.

BACKGROUND: Cisplatin (CDDP) ototoxicity is a significant side effect of the current treatment of medulloblastoma (MB). Cumulative dose of CDDP and age are recognized risk factors for hearing loss, but inter-individual susceptibility limits our ability to identify patients at risk for hearing loss. We describe the kinetics of early audiometric changes during therapy and identify profiles associated with a higher risk of needing hearing aids. PROCEDURE: Serial audiometric evaluations were performed during and after completion of therapy in children with average risk (AR) and high-risk (HR) MB. Each audiogram was scored according to five grading systems. Variations of pure tone thresholds were analyzed at each frequency for each consecutive audiogram. CDDP dose modifications and hearing outcome were recorded. RESULTS: A total of 258 audiograms from 35 patients (22 AR, 13 HR) were analyzed. Eighteen AR patients (81.3%) required dose reduction and the median cumulative dose of CDDP administered was 412.5 mg/m(2) (150-600), corresponding to 68% of the intended dose. Three HR patients (23.0%) required dose reduction. At a median follow-up of 67 months (11-117), nine patients (25.7%) required hearing support: After two cycles of CDDP (150 mg/m(2) ), the average hearing loss at 8,000 Hz was twice higher in the group that eventually required hearing support. CONCLUSION: Early alteration of high-frequency thresholds may help identify individuals who will require hearing support. In the MB population, alternative strategies should be developed to limit the cumulative dose of CDDP to prevent significant ototoxicity.

You are in charge now: exploration of educational relationships between anaesthetic trainees and their supervising specialists.

Background: Much of the education during anaesthesia training occurs in the workplace where trainees work under the close supervision of a more senior anaesthetist. Trainee anaesthetists are exposed to multiple supervisors with whom they form educational and supervisory relationships over the course of their training. Surprisingly little research has been conducted to explore the factors behind the development and maintenance of these relationships. This study explores the process of how education occurs in the workplace by examining the relationship from the perspective of both trainees and specialists. Methods: This is an exploratory qualitative study. Eight trainee and 10 specialist anaesthetists participated in an individual semi-structured interview. The data were analysed thematically by each of the authors to generate themes. Results: Six themes were identified in the analysis: (1) sizing up; (2) negotiated autonomy; (3) working closely together; (4) workplace practices; (5) education being valued; and (6) gender. A conceptual model to illustrate the relationships between the six themes was developed. Conclusions: Supervisory relationships were viewed positively by participants despite impediments such as lack of continuity and busy clinical environments. But there were tensions, particularly in balancing trainee autonomy with patient safety. A nuanced 'sizing up' process, with negotiation of autonomy, was described by both supervisors and trainees. Our findings may support supervisory relationships to reach this ideal more effectively.

Exploring equity, diversity, and inclusion in a simulation program using the SIM-EDI tool: the impact of a reflexive tool for simulation educators.

BACKGROUND: There have been increasing calls for awareness and action related to equity, diversity, and inclusion (EDI) in simulation but a lack of practical guidance for how simulation delivery teams (SDTs) might move towards meaningful transformation. The gap between academic conversations about EDI and how to practically impact SDT attitudes, behaviors, and performance remains considerable. We designed a conversational tool, the SIM-EDI, to bridge the gap between theory and practice for SDTs by enhancing reflexivity and studied its impact locally. METHODS: We engaged in a collaborative autoethnography to explore EDI within our emergency department SDT shortly after implementing the SIM-EDI. The 12-month ethnography is informed by our team's collection and analysis of data about ourselves and our own experiences using the tool. Data included serial interviews, field notes from simulations and SDT meetings, SDT documents, and self-reflections. RESULTS: We found the SIM-EDI tool could be implemented with a team with a high level of readiness. Use of the tool had several meaningful impacts including enhanced team reflexivity, normalization of conversations related to EDI and increased confidence to engage in EDI conversations with participants. Key themes throughout the process included (1) individual and team growth, (2) fear of "getting it wrong", and (3) tension between bias towards action and need for slow reflection. CONCLUSION: The SIM-EDI tool can effectively promote reflexivity among faculty in an emergency department simulation program. The tool is easy to use and implement, impacts attitudes and behaviors, and facilitates individual and team growth.

Faculty development for translational simulation: a qualitative study of current practice.

BACKGROUND: Translational simulation is focused directly on healthcare quality, safety, and systems. Effective translational simulation design and delivery may require knowledge and skills in areas like quality improvement and safety science. How translational simulation programs support their faculty to learn these skills is unknown. We aimed to explore current faculty development practices within translational simulation programs, and the rationale for the approaches taken. METHODS: We used a qualitative approach to explore faculty development in translational simulation programs. We conducted semi-structured interviews with representatives who have leadership and/or faculty development responsibilities in these programs and performed a thematic analysis of the data. RESULTS: Sixteen interviews were conducted with translational simulation program leaders from nine countries. We identified three themes in our exploration of translational simulation faculty development practices: (1) diverse content, (2) 'home-grown', informal processes, and (3) the influence of organisational context. Collaboration beyond the historical boundaries of the healthcare simulation community was an enabler across themes. CONCLUSION: Leaders in translational simulation programs suggest a diverse array of knowledge and skills are important for translational simulation faculty and report a range of informal and formal approaches to the development of these skills. Many programs are early in the development of their approach to faculty development, and all are powerfully influenced by their context; the program aims, structure, and strategy.

Psychological safety and emergency department team performance: A mixed-methods study.

OBJECTIVES: Team culture underpins team performance. Psychological safety - 'a shared belief held by members of a team that the team is safe for interpersonal risk taking' - is a critical component of team culture for high-performing teams across contexts. However, psychological safety in ED teams has not been well explored. We aimed to explore this core teamwork concept in the ED. METHODS: This was a sequential mixed-methods study of nursing and medical staff at a large tertiary care ED in Australia from October 2020 to March 2021. First, participants completed the 'Team Learning and Psychological Safety Survey' and a narrative questionnaire. These findings informed semi-structured interviews. We determined median psychological safety and compared results across role and length of time working in the department. Qualitative results were analysed using a deductive thematic analysis using a previously generated framework for enablers of psychological safety at the individual, team and organisational levels. RESULTS: The survey was completed by 72/410 participants and 19 interviews were conducted. The median psychological safety score was 37/49 (IQR 13). Psychological safety was not experienced universally, with nurses and new staff experiencing lower levels. Individual, team and organisational factors impacted psychological safety. The primary force shaping psychological safety was familiarity with colleagues and leaders. CONCLUSION: Familiarity of team members and leaders was critical to the development of psychological safety within the ED. Fostering familiarity should be a focus for frontline leadership each shift and a priority in broader departmental decisions for those seeking to enhance the psychological safety of their teams.

Exploring participant experience to optimize the design and delivery of stress exposure simulations in emergency medicine.

Objectives: Emergency department (ED) teams frequently perform under conditions of high stress. Stress exposure simulation (SES) is specifically designed to train recognition and management of stress responses under these conditions. Current approaches to design and delivery of SES in emergency medicine are based on principles derived from other contexts and from anecdotal experience. However, the optimal design and delivery of SES in emergency medicine are not known. We aimed to explore participant experience to inform our approach. Methods: We performed an exploratory study in our Australian ED with doctors and nurses participating in SES sessions. We used a three-part framework-sources of stress, the impacts of that stress, and the strategies to mitigate-to inform our SES design and delivery and to guide our exploration of participant experience. Data were collected through a narrative survey and participant interviews and analyzed thematically. Results: There were 23 total participants (doctors n = 12, nurses n = 11) across the three sessions. Sixteen survey responses and eight interview transcripts were analyzed, each with equal numbers of doctors and nurses. Five themes were identified in data analysis: (1) experience of stress, (2) managing stress, (3) design and delivery of SES, (4) learning conversations, and (5) transfer to practice. Conclusions: We suggest that design and delivery of SES should follow health care simulation best practice, with stress adequately induced by authentic clinical scenarios and to avoid trickery or adding extraneous cognitive load. Facilitators leading learning conversations in SES sessions should develop a deep understanding of stress and emotional activation and focus on team-based strategies to mitigate harmful impacts of stress on performance.

Wearing hats and blending boundaries: harmonising professional identities for clinician simulation educators.

Many clinicians working in healthcare simulation struggle with competing dual identities of clinician and educator, whilst those who harmonise these identities are observed to be highly effective teachers and clinicians. Professional identity formation (PIF) theories offer a conceptual framework for considering this dilemma. However, many clinician simulation educators lack practical guidance for translating these theories and are unable to develop or align their dual identities.An unusual experience involving the first author's suspension of disbelief as a simulation facilitator sparked a novel reflection on his dual identity as a clinician and as a simulation educator. He re-framed his clinician and simulation 'hats' as cooperative and fluid rather than competing and compartmentalised. He recognised that these dual identities could flow between clinical and simulation environments through leaky 'blended boundaries' rather than being restricted by environmental demarcations.This personal story is shared and reflected upon to offer a practical 'hats and boundaries' model. Experimenting with the model in both clinical and simulation workplaces presents opportunities for PIF and alignment of dual identities. The model may help other clinician simulation educators navigate the complexities of merging their dual identities.

Taking simulation out of its "safe container"-exploring the bidirectional impacts of psychological safety and simulation in an emergency department.

BACKGROUND: Simulation facilitators strive to ensure the psychological safety of participants during simulation events; however, we have limited understanding of how antecedent levels of psychological safety impact the simulation experience or how the simulation experience impacts real-world psychological safety. METHODS: We explored the experience of participants in an embedded, interprofessional simulation program at a large tertiary emergency department (ED) in Australia. We engaged in theoretical thematic analysis of sequential narrative surveys and semi-structured interviews using a previously derived framework of enablers of psychological safety in healthcare. We sought to understand (1) how real-world psychological safety impacts the simulation experience and (2) how the simulation experience influences real-world psychological safety. RESULTS: We received 74 narrative responses and conducted 19 interviews. Simulation experience was both influenced by and impacted psychological safety experienced at the individual, team, and organizational levels of ED practice. Most strikingly, simulation seemed to be an incubator of team familiarity with direct impact on real-world practice. We present a model of the bidirectional impact of psychological safety and simulation within healthcare environments. CONCLUSION: Our model represents both opportunity and risk for facilitators and organizations engaging in simulation. It should inform objectives, design, delivery, debriefing, and faculty development and firmly support the situation of simulation programs within the broader cultural ethos and goals of the departments and organizations.

COVID-19 has heightened tensions between and exposed threats to core values of emergency medicine.

BACKGROUND: Professional culture is a powerful influence in emergency departments, but incompletely understood. Disasters magnify cultural realities, and as such the COVID-19 pandemic offered a unique opportunity to better understand emergency medicine (EM) values, practices, and beliefs. METHODS: We conducted a collaborative ethnography at a tertiary care center during the acute phase of the response to the threat of COVID-19 (March-May 2020). Collaborative ethnography is a method that partners directly with communities during design, data gathering, and analysis to study culture. An ED-based research team gathered data including field notes from 300 h of participant observation and informal interviews, 42 semi-structured interviews, and 57 departmental documents. Data were deductively coded using a previously generated framework for understanding EM culture. RESULTS: Each of seven core values from the original framework were identified in the dataset and further contextualized understanding of EM culture. COVID-19 exacerbated pre-existing tensions and threats to the core values of EM. For example, the desire to provide patient-centered care was impeded by strict visitor restrictions; the ability to treat life-threatening illness was impaired by new resuscitation room layouts and infection control procedures; and subtle changes in protocols had downstream impact on flow and the ability to balance needs and resources at a system level. The cultural values related to teams were protective and strengthened during this time. The pandemic exposed problems with the status quo, underscored inherent tensions between ED values, and highlighted threats to self-identity. CONCLUSION: COVID-19 has highlighted and compounded existing tensions and threats to the core values of EM, underscoring a critical mismatch between values and practice. Realignment of the realities of ED work with staff values is urgently needed.

RéSUMé: CONTEXTE: La culture professionnelle est une influence puissante dans les services d'urgence, mais elle est incomplètement comprise. Les catastrophes amplifient les réalités culturelles et, à ce titre, la pandémie de COVID-19 a offert une occasion unique de mieux comprendre les valeurs, les pratiques et les croyances de la médecine d'urgence (MU). MéTHODES: Nous avons mené une ethnographie collaborative dans un centre de soins tertiaires pendant la phase aiguë de la réponse à la menace du COVID-19 (mars-mai 2020). L'ethnographie collaborative est une méthode qui s'associe directement aux communautés pendant la conception, la collecte de données et l'analyse pour étudier la culture. Une équipe de recherche basée à l'urgence a recueilli des données, y compris des notes de terrain tirées de 300 heures d'observation des participants et d'entrevues informelles, de 42 entrevues semi-structurées et de 57 documents ministériels. Les données ont été codées de manière déductive à l'aide d'un cadre précédemment créé pour comprendre la culture de la MU. RéSULTATS: Chacune des sept valeurs fondamentales du cadre original a été identifiée dans l'ensemble de données et a permis de mieux comprendre la culture de la MU. COVID-19 a exacerbé les tensions préexistantes et les menaces qui pèsent sur les valeurs fondamentales de la MU. Par exemple, le désir de fournir des soins centrés sur le patient a été entravé par des restrictions strictes concernant les visiteurs ; la capacité de traiter des maladies potentiellement mortelles a été compromise par les nouvelles dispositions des salles de réanimation et des procédures de contrôle des infections ; et des changements subtils dans les protocoles ont eu un impact en aval sur le flux et la capacité à équilibrer les besoins et les ressources au niveau du système. Les valeurs culturelles liées aux équipes étaient protectrices et renforcées pendant cette période. La pandémie a mis en évidence les problèmes liés au statu quo, souligné les tensions inhérentes entre les valeurs des services d'urgence et mis en évidence les menaces pour l'identité personnelle. CONCLUSION: COVID-19 a mis en évidence et aggravé les tensions et les menaces existantes pour les valeurs fondamentales de la MU, soulignant un décalage critique entre les valeurs et la pratique. Il est urgent de réaligner les réalités du travail dans les services d'urgence sur les valeurs du personnel.

Review article: A primer for clinical researchers in the emergency department: Part XI. Inertia before investigation: Pre-test probability in emergency medicine.

In this series, we address research topics in emergency medicine. Rational clinical decision making is based on knowledge of the disease prevalence, clinical assessment features and test characteristics such as sensitivity and specificity. The concept of pre-test probability is important as it will allow the clinician and patient decide together if a 'test threshold' or 'treatment threshold' has been reached, or if further investigations are required to make such a decision. This research primer uses three case scenarios to explore these concepts.

Doing our work better, together: a relationship-based approach to defining the quality improvement agenda in trauma care.

BACKGROUND: Trauma care represents a complex patient journey, requiring multidisciplinary coordinated care. Team members are human, and as such, how they feel about their colleagues and their work affects performance. The challenge for health service leaders is enabling culture that supports high levels of collaboration, co-operation and coordination across diverse groups. We aimed to define and improve relational aspects of trauma care at Gold Coast University Hospital. METHODS: We conducted a mixed-methods collaborative ethnography using the relational coordination survey-an established tool to analyse the relational dimensions of multidisciplinary teamwork-participant observation, interviews and narrative surveys. Findings were presented to clinicians in working groups for further interpretation and to facilitate co-creation of targeted interventions designed to improve team relationships and performance. FINDINGS: We engaged a complex multidisciplinary network of ~500 care providers dispersed across seven core interdependent clinical disciplines. Initial findings highlighted the importance of relationships in trauma care and opportunities to improve. Narrative survey and ethnographic findings further highlighted the centrality of a translational simulation programme in contributing positively to team culture and relational ties. A range of 16 interventions-focusing on structural, process and relational dimensions-were co-created with participants and are now being implemented and evaluated by various trauma care providers. CONCLUSIONS: Through engagement of clinicians spanning organisational boundaries, relational aspects of care can be measured and directly targeted in a collaborative quality improvement process. We encourage healthcare leaders to consider relationship-based quality improvement strategies, including translational simulation and relational coordination processes, in their efforts to improve care for patients with complex, interdependent journeys.
