Impact of individualized feedback letters on adherence to surgical antibiotic prophylaxis guidelines: an interrupted time series study (FEEDBACK-ASAP).

BACKGROUND: Surgical antibiotic prophylaxis (SAP) has been proved to decrease the rate of surgical site infections (SSI), but compliance to SAP guidelines remains suboptimal. AIM: This study evaluated the impact of periodically sending individualized feedback letters to surgeons and anesthesiologists on their compliance rate to SAP guidelines. METHODS: A total of 1491 surgeries were evaluated by retrospective chart review during the pre-intervention period and 668 surgeries were evaluated by prospective chart review during the per-intervention period. Finally, 295 letters were sent to 64 surgeons and 45 anesthesiologists. Compliance rate was assessed as an outcome composed of: indication for SAP, choice of antibiotic agent, antibiotic dose, postoperative duration, timing of the preoperative dose and intraoperative redosing. An interrupted time series design was used to assess a difference on compliance rates before and during the intervention period. FINDINGS: Sending individualized feedback letters to surgeons and anesthesiologists did not significantly improve the overall compliance to local SAP guidelines. CONCLUSION: Individualized feedback letters could be part of future interventions directed at improving compliance to SAP guidelines, but are likely insufficient by themselves to provide significant results.

The responsibility to care: lessons learned from emergency department workers' perspectives during the first wave of the COVID-19 pandemic in Canada.

BACKGROUND: This study's objective was to examine emergency department (ED) workers' perspectives during the Canadian COVID-19 first wave. METHODS: This qualitative study included workers from nine Canadian EDs who participated in 3 monthly video focus groups between April and July 2020 to explore (1) personal/professional experiences, (2) patient care and ED work, (3) relationships with teams, institutions and governing bodies. Framework analysis informed data collection and analysis. RESULTS: Thirty-six focus groups and 15 interviews were conducted with 53 participants (including 24 physicians, 16 nurses). Median age was 37.5 years, 51% were female, 79% had more than 5 years' experience. Three main themes emerged. (1) Early in this pandemic, participants felt a responsibility to provide care to patients and solidarity toward their ED colleagues and team, while balancing many risks with their personal protection. (2) ED teams wanted to be engaged in decision-making, based on the best available scientific knowledge. Institutional decisions and clinical guidelines needed to be adapted to the specificity of each ED environment. (3) Working during the pandemic created new sources of moral distress and fatigue, including difficult clinical practices, distance with patients and families, frequent changes in information and added sources of fatigue. Although participants quickly adapted to a "new normal", they were concerned about long-term burnout. Participants who experienced high numbers of patient deaths felt especially unprepared. INTERPRETATION: ED workers believe they have a responsibility to provide care through a pandemic. Trust in leadership is supported by managers who are present and responsive, transparent in their communication, and involve ED staff in the development and practice of policies and procedures. Such practices will help protect from burnout and ensure the workforce's long-term sustainability.

RéSUMé: CONTEXTE: Cette étude avait pour objectif d'examiner le point de vue des travailleurs des services d'urgence pendant la première vague de la COVID-19 au Canada. MéTHODES: Cette étude qualitative a inclus des travailleurs de neuf services d'urgence canadiens qui ont participé à 3 groupes de discussion monsuels par visioconférence entre avril et juillet 2020, pour explorer: (1) leurs expériences personnelles/professionnelles, (2) les soins aux patients et le travail au service d'urgence, (3) leurs relations avec les équipes, les institutions et instances dirigeantes. Le "framework analysis" a guidé le receuil et l'analyse des données. RéSULTATS: Trente-six groupes de discussion et 15 entretiens individuels ont été menés avec 53 participants (dont 24 médecins et 16 infirmières). L'âge médian était de 37,5 ans, 51% étaient des femmes, 79% avaient plus de 5 ans d'expérience. Trois thèmes principaux sont ressortis. (1) Au début de cette pandémie, les participants se sont sentis responsables de prodiguer des soins aux patients et solidaires envers leurs collègues et leurs équipes des urgences, tout en cherchant à équilibrer la gestion de nombreux risques et leur protection personnelle. (2) Les équipes des services d'urgence souhaitaient participer aux prises de décision, informées par les meilleures connaissances scientifiques disponibles. Les décisions institutionnelles et les lignes directrices cliniques doivent être adaptées à la spécificité de chaque salle d'urgence. (3) Travailler pendant la pandémie a créé de nouvelles sources de détresse morale et de fatigue, notamment des pratiques cliniques difficiles, la distance avec les patients et les familles, les changements fréquents d'information. Bien que les participants se soient rapidement adaptés à une « nouvelle normalité¼, ils étaient préoccupés par l'épuisement professionnel des travailleurs au long terme. Les participants qui ont vécu un nombre élevé de décès de patients à l'urgence se sentaient particulièrement mal préparés. INTERPRéTATION: Les travailleurs des services d'urgence estiment qu'ils ont la responsabilité de fournir des soins en cas de pandémie. Un sentiment de confiance dans les décideurs peut être soutenu par des gestionnaires qui sont présents et réactifs, transparents dans leur communication, et qui impliquent le personnel des services d'urgence dans le développement des politiques et procédures cliniques. De telles pratiques aideront à protéger contre l'épuisement professionnel pour garantir le bien-être des travailleurs d'urgence.

Efficacy and cost-feasibility of the Timely Chest Compression Training (T-CCT): a contextualized cardiopulmonary resuscitation training for personal support workers participating during in-hospital cardiac arrests.

OBJECTIVES: The Timely Chest Compression Training (T-CCT) was created to promote more frequent training in chest compressions for personal support workers. This study aims to assess the efficacy of the T-CCT on the chest compression performance and to examine costs related to this intervention. METHODS: A prospective single group, before-after study was conducted at a university-affiliated hospital. The T-CCT is adapted for support workers and lasts 20 min during working hours. Guided by peer trainers, live feedback devices and mannikins, the T-CCT targets chest compression training. Using an algorithm, chest compression performance scores were gathered before and after the intervention. RESULTS: Of 875 employed support workers, 573 were trained in 5 days. Prior to the intervention, the median performance score was 72%. Participants significantly improved after the intervention (p < 0.001) and the median of the differences was 32% (95% CI 28.5-36.0). Support workers in critical care units and those with an active basic life support (BLS) certification performed better at baseline and were less inclined to have large changes in performance scores after the intervention. When compared to basic life support training, the T-CCT is over three times less expensive. CONCLUSIONS: The T-CCT was an effective and low-cost initiative that allowed to train a large group of support workers in a short amount of time. Since they are actively involved in resuscitation efforts in Quebec (Canada), it may promote the delivery of high-quality compressions during in-hospital cardiac arrests. Our inquiry can incite and guide other organizations in the implementation of similar interventions.

RéSUMé: OBJECTIFS: Le Timely Chest Compression Training (T-CCT) a été créé pour promouvoir une formation plus fréquente en compressions thoraciques pour les préposés aux bénéficiaires. Cette étude vise à évaluer l'efficacité du T-CCT sur la performance en compressions thoraciques et à examiner les coûts liés à cette intervention. MéTHODES: Une étude prospective avant-après avec un seul groupe a été menée dans un hôpital universitaire. Le T-CCT est adapté aux préposés aux bénéficiaires et dure 20 min pendant les heures de travail. Guidé par des pairs formateurs, des appareils de rétroaction en direct et des mannequins, le T-CCT cible l'entraînement des compression thoraciques. À l'aide d'un algorithme, les scores de performance en compression thoraciques ont été recueillis avant et après l'intervention. RéSULTATS: Sur les 875 préposés aux bénéficiaires employés, 573 ont été formés en cinq jours. Avant l'intervention, le score de performance médian était de 72 %. Les participants se sont nettement améliorés après l'intervention (p < 0.001) et la médiane des différences était de 32 % (IC à 95 %, 28.5−36.0). Les préposés aux bénéficiaires dans les unités de soins intensifs et ceux avec une formation de réanimation cardiorespiratoire de base (BLS) active ont obtenu de meilleurs résultats au départ et étaient moins enclins à avoir de grands changements dans leurs scores de performance après l'intervention. Comparé à la formation BLS, le T-CCT est trois fois moins cher. CONCLUSIONS: Le T-CCT était une initiative efficace et peu coûteuse qui a permis la formation d'un grand groupe de préposés aux bénéficiaires en peu de temps. Étant donné qu'ils sont activement impliqués dans les efforts de réanimation au Québec (Canada), cela pourrait favoriser la réalisation de compressions de grande qualité pendant les arrêts cardiorespiratoires en milieu hospitalier. Notre démarche pourra inciter et guider d'autres organisations dans la mise en œuvre d'interventions similaires.

Evaluation of a National Competency-Based Assessment System in Emergency Medicine: A CanDREAM Study.

BACKGROUND: In 2018, Canadian postgraduate emergency medicine (EM) programs began implementing a competency-based medical education (CBME) assessment program. Studies evaluating these programs have focused on broad outcomes using data from national bodies and lack data to support program-specific improvement. OBJECTIVE: We evaluated the implementation of a CBME assessment program within and across programs to identify successes and opportunities for improvement at the local and national levels. METHODS: Program-level data from the 2018 resident cohort were amalgamated and analyzed. The number of entrustable professional activity (EPA) assessments (overall and for each EPA) and the timing of resident promotion through program stages were compared between programs and to the guidelines provided by the national EM specialty committee. Total EPA observations from each program were correlated with the number of EM and pediatric EM rotations. RESULTS: Data from 15 of 17 (88%) programs containing 9842 EPA observations from 68 of 77 (88%) EM residents in the 2018 cohort were analyzed. Average numbers of EPAs observed per resident in each program varied from 92.5 to 229.6, correlating with the number of blocks spent on EM and pediatric EM (r = 0.83, P < .001). Relative to the specialty committee's guidelines, residents were promoted later than expected (eg, one-third of residents had a 2-month delay to promotion from the first to second stage) and with fewer EPA observations than suggested. CONCLUSIONS: There was demonstrable variation in EPA-based assessment numbers and promotion timelines between programs and with national guidelines.

Cross-diffractive optical elements for wide angle geometric camera calibration.

Diffractive optical elements (DOEs) can generate multiple two-dimensional (2D) diffraction grids that can be used to calibrate cameras for photogrammetry. However, several factors limit the accuracy and the functionality of this technique. One of the most important is the DOE fabrication itself. A large DOE with wide 2D fan-out grids is very difficult and costly to develop. Consequently, the calibration is limited to small aperture cameras and/or limited angles. To overcome these problems, we present a low cost solution. We propose to use two large, commercially available, crossed phase DOEs that generate 15×15 equally spaced dots. As the DOEs are not perfect, the unwanted secondary diffractive orders are used as calibration targets to expand the calibration field of view. We show that the use of the primary and secondary diffractive orders provides a valuable calibration tool for wide angle aerial cameras.

[Clinical management. A always current tool]. / La démarche clinique. Un outil toujours d'actualité.

Clinical reasoning is the fundamental tool every clinician must master. This paper gives a definition of clinical reasoning process using real cases and presents some of the cognitive models underlying it (especially the script concept). We discuss the caveats of clinical reasoning process and its impact on interdisciplinary work, the use of technologies and medical teaching.
