Association Between Anesthesiologist Sex and Patients' Postoperative Outcomes: A Population-based Cohort Study.

OBJECTIVE: To examine the association of anesthesiologist sex on postoperative outcomes. BACKGROUND: Differences in patient postoperative outcomes exist, depending on whether the primary surgeon is male or female, with better outcomes seen among patients treated by female surgeons. Whether the intraoperative anesthesiologist's sex is associated with differential postoperative patient outcomes is unknown. METHODS: We performed a population-based, retrospective cohort study among adult patients undergoing one of 25 common elective or emergent surgical procedures from 2007 to 2019 in Ontario, Canada. We assessed the association between the sex of the intraoperative anesthesiologist and the primary end point of the adverse postoperative outcome, defined as death, readmission, or complication within 30 days after surgery, using generalized estimating equations. RESULTS: Among 1,165,711 patients treated by 3006 surgeons and 1477 anesthesiologists, 311,822 (26.7%) received care from a female anesthesiologist and 853,889 (73.3%) from a male anesthesiologist. Overall, 10.8% of patients experienced one or more adverse postoperative outcomes, of whom 1.1% died. Multivariable adjusted rates of the composite primary end point were higher among patients treated by male anesthesiologists (10.6%) compared with female anesthesiologists (10.4%; adjusted odds ratio 1.02, 95% CI: 1.00-1.05, P =0.048). CONCLUSIONS: We demonstrated a significant association between sex of the intraoperative anesthesiologist and patient short-term outcomes after surgery in a large cohort study. This study supports the growing literature of improved patient outcomes among female practitioners. The underlying mechanisms of why outcomes differ between male and female physicians remain elusive and require further in-depth study.

Association between anaesthesia-surgery team sex diversity and major morbidity.

BACKGROUND: Team diversity is recognized not only as an equity issue but also a catalyst for improved performance through diversity in knowledge and practices. However, team diversity data in healthcare are limited and it is not known whether it may affect outcomes in surgery. This study examined the association between anaesthesia-surgery team sex diversity and postoperative outcomes. METHODS: This was a population-based retrospective cohort study of adults undergoing major inpatient procedures between 2009 and 2019. The exposure was the hospital percentage of female anaesthetists and surgeons in the year of surgery. The outcome was 90-day major morbidity. Restricted cubic splines were used to identify a clinically meaningful dichotomization of team sex diversity, with over 35% female anaesthetists and surgeons representing higher diversity. The association with outcomes was examined using multivariable logistic regression. RESULTS: Of 709 899 index operations performed at 88 hospitals, 90-day major morbidity occurred in 14.4%. The median proportion of female anaesthetists and surgeons was 28 (interquartile range 25-31)% per hospital per year. Care in hospitals with higher sex diversity (over 35% female) was associated with reduced odds of 90-day major morbidity (OR 0.97, 95% c.i. 0.95 to 0.99; P = 0.02) after adjustment. The magnitude of this association was greater for patients treated by female anaesthetists (OR 0.92, 0.88 to 0.97; P = 0.002) and female surgeons (OR 0.83, 0.76 to 0.90; P < 0.001). CONCLUSION: Care in hospitals with greater anaesthesia-surgery team sex diversity was associated with better postoperative outcomes. Care in a hospital reaching a critical mass with over 35% female anaesthetists and surgeons, representing higher team sex-diversity, was associated with a 3% lower odds of 90-day major morbidity.

A matter of life and death: physician gender and patient outcomes after surgery.

Accumulating evidence supports an effect of physician gender (or sex, a surrogate used in many studies) on important patient outcomes such as death, complications, and hospital length of stay. Recent studies suggest that these effects result from the gender diversity of the team rather than individual physician gender. Here, we reflect on the potential mechanisms of an effect of physician gender on patient outcomes.

Association of chronic poststernotomy pain and health-related quality of life: a prospective cohort study.

PURPOSE: Chronic poststernotomy pain (CPSP) after cardiac surgery is multifactorial and impacts patient recovery. We aimed to evaluate the association between CPSP severity and health-related quality of life at six months after cardiac surgery. METHODS: This was a single-centre prospective cohort study of patients who underwent cardiac surgery with median sternotomy between September 2020 and March 2021. Telephone interviews were conducted at six and 12 months postoperatively using the Short Form McGill Pain Questionnaire and the EQ-5D-5L. Strength of correlation was described using Spearman's correlation coefficient. Multivariable regression analysis was used to account for confounding variables. RESULTS: A total of 252 patients responded to the six-month interview (response rate, 65%). The mean (standard deviation) age of respondents was 65 (13) yr. Twenty-nine percent of respondents (72/252) reported CPSP at six months, and 14% (41/252) reported more than mild pain (score ≥ 2/5). At 12 months, of the 89% (64/72) patients who responded, 47% (30/64) still reported pain. The strength of the correlation between pain scores and EQ-5D-5L was weak (Spearman's correlation coefficient, -0.3). Risk factors for CPSP at six months included higher pain score on postoperative day 1, history of chronic pain prior to surgery, and history of depression. Intraoperative infusion of dexmedetomidine or ketamine was associated with a reduced risk of CPSP at six months. CONCLUSION: Chronic poststernotomy pain still affects patient recovery at six and 12 months after cardiac surgery. The severity of that pain is poorly correlated with patients' quality of life.

RéSUMé: OBJECTIF: La douleur chronique post-sternotomie (DCPS) après une chirurgie cardiaque est multifactorielle et a un impact sur le rétablissement des patient·es. Nous avons cherché à évaluer l'association entre la sévérité de la DCPS et la qualité de vie liée à la santé six mois après la chirurgie cardiaque. MéTHODE: Il s'agissait d'une étude de cohorte prospective monocentrique portant sur des patient·es ayant bénéficié d'une chirurgie cardiaque avec sternotomie médiane entre septembre 2020 et mars 2021. Des entrevues téléphoniques ont été menées à six et 12 mois après l'opération en se servant du questionnaire abrégé de McGill sur la douleur et de l'EQ-5D-5L. La force de corrélation a été décrite à l'aide du coefficient de corrélation de Spearman. Une analyse de régression multivariée a été utilisée pour tenir compte des variables confondantes. RéSULTATS: Au total, 252 patient·es ont répondu à l'entrevue à six mois (taux de réponse de 65 %). L'âge moyen (écart type) des répondant·es était de 65 (13) ans. Vingt-neuf pour cent des personnes répondantes (72/252) ont déclaré avoir été atteintes de DCPS à six mois, et 14 % (41/252) ont signalé une douleur plus que légère (score ≥ 2/5). À 12 mois, sur les 89 % (64/72) personnes ayant répondu, 47 % (30/64) signalaient encore de la douleur. La force de la corrélation entre les scores de douleur et l'EQ-5D-5L était faible (coefficient de corrélation de Spearman, −0,3). Les facteurs de risque de DCPS à six mois comprenaient un score de douleur plus élevé au jour 1 postopératoire, des antécédents de douleur chronique avant la chirurgie et des antécédents de dépression. Une perfusion peropératoire de dexmédétomidine ou de kétamine a été associée à une réduction du risque de DCPS à six mois. CONCLUSION: La douleur chronique post-sternotomie affecte toujours le rétablissement des patient·es six et 12 mois après la chirurgie cardiaque. La sévérité de cette douleur est faiblement corrélée à la qualité de vie des patient·es. ENREGISTREMENT DE L'éTUDE: www.osf.io ( https://osf.io/52rsw ); enregistrée le 14 mai 2022.

Variation in Anesthesiology Provider-Volume for Complex Gastrointestinal Cancer Surgery: A Population-Based Study.

OBJECTIVE: Examine between-hospital and between-anesthesiologist variation in anesthesiology provider-volume (PV) and delivery of high-volume anesthesiology care. BACKGROUND: Better outcomes for anesthesiologists with higher PV of complex gastrointestinal cancer surgery have been reported. The factors linking anesthesiology practice and organization to volume are unknown. METHODS: We identified patients undergoing elective esophagectomy, hepatectomy, and pancreatectomy using linked administrative health data sets (2007-2018). Anesthesiology PV was the annual number of procedures done by the primary anesthesiologist in the 2 years before the index surgery. High-volume anesthesiology was PV>6 procedures/year. Funnel plots to described variation in anesthesiology PV and delivery of high-volume care. Hierarchical regression models examined between-anesthesiologist and between-hospital variation in delivery of high-volume care use with variance partition coefficients (VPCs) and median odds ratios (MORs). RESULTS: Among 7893 patients cared for at 17 hospitals, funnel plots showed variation in anesthesiology PV (median ranging from 1.5, interquartile range: 1-2 to 11.5, interquartile range: 8-16) and delivery of HV care (ranging from 0% to 87%) across hospitals. After adjustment, 32% (VPC 0.32) and 16% (VPC: 0.16) of the variation were attributable to between-anesthesiologist and between-hospital differences, respectively. This translated to an anesthesiologist MOR of 4.81 (95% CI, 3.27-10.3) and hospital MOR of 3.04 (95% CI, 2.14-7.77). CONCLUSIONS: Substantial variation in anesthesiology PV and delivery of high-volume anesthesiology care existed across hospitals. The anesthesiologist and the hospital were key determinants of the variation in high-volume anesthesiology care delivery. This suggests that targeting anesthesiology structures of care could reduce variation and improve delivery of high-volume anesthesiology care.

The Association Between Hospital High-volume Anesthesiology Care and Patient Outcomes for Complex Gastrointestinal Cancer Surgery: A Population-based Study.

OBJECTIVE: To examine the association of between hospital rates of high-volume anesthesiology care and of postoperative major morbidity. BACKGROUND: Individual anesthesiology volume has been associated with individual patient outcomes for complex gastrointestinal cancer surgery. However, whether hospital-level anesthesiology care, where changes can be made, influences the outcomes of patients cared at this hospital is unknown. METHODS: We conducted a population-based retrospective cohort study of adults undergoing esophagectomy, pancreatectomy, or hepatectomy for cancer from 2007 to 2018. The exposure was hospital-level adjusted rate of high-volume anesthesiology care. The outcome was hospital-level adjusted rate of 90-day major morbidity (Clavien-Dindo grade 3-5). Scatterplots visualized the relationship between each hospital's adjusted rates of high-volume anesthesiology and major morbidity. Analyses at the hospital-year level examined the association with multivariable Poisson regression. RESULTS: For 7893 patients at 17 hospitals, the rates of high-volume anesthesiology varied from 0% to 87.6%, and of major morbidity from 38.2% to 45.4%. The scatter plot revealed a weak inverse relationship between hospital rates of high-volume anesthesiology and of major morbidity (Pearson: -0.23). The adjusted hospital rate of high-volume anesthesiology was independently associated with the adjusted hospital rate of major morbidity (rate ratio: 0.96; 95% CI, 0.95-0.98; P <0.001 for each 10% increase in the high-volume rate). CONCLUSIONS: Hospitals that provided high-volume anesthesiology care to a higher proportion of patients were associated with lower rates of 90-day major morbidity. For each additional 10% patients receiving care by a high-volume anesthesiologist at a given hospital, there was an associated reduction of 4% in that hospital's rate of major morbidity.

Healthcare delivery gaps in pain management within the first 3 months after discharge from inpatient noncardiac surgeries: a scoping review.

BACKGROUND: Poor pain control during the postoperative period has negative implications for recovery, and is a critical risk factor for development of persistent postsurgical pain. The aim of this scoping review is to identify gaps in healthcare delivery that patients undergoing inpatient noncardiac surgeries experience in pain management while recovering at home. METHODS: Searches were conducted by a medical librarian in PubMed, MEDLINE, EMBASE, EBSCO CINAHL, Web of Science, and Cochrane Database of Systematic Reviews for articles published between 2016 and 2022. Inclusion criteria were adults (≥18 yr), English language, inpatient noncardiac surgery, and included at least one gap in care for acute and/or persistent pain management after surgery within the first 3 months of recovery at home. Two reviewers independently screened articles for inclusion and extracted data. Quotations from each article related to gaps in care were synthesised using thematic analysis. RESULTS: There were 4794 results from databases and grey literature, of which 38 articles met inclusion criteria. From these, 23 gaps were extracted, encompassing all six domains of healthcare delivery (capacity, organisational structure, finances, patients, care processes and infrastructure, and culture). Identified gaps were synthesised into five overarching themes: education (22 studies), provision of continuity of care (21 studies), individualised management (10 studies), support for specific populations (11 studies), and research and knowledge translation (10 studies). CONCLUSIONS: This scoping review identified health delivery gaps during a critical period in postoperative pain management. These gaps represent potential targets for quality improvement and future research to improve perioperative care and longer-term patient-centred outcomes.

A comparison of patient-reported outcomes among Canadian women having hysterectomies.

PURPOSE: Many indications for hysterectomy can negatively affect patients' quality of life. This study uses patient-reported outcomes to measure changes in self-reported health among hysterectomy patients. METHOD: A prospective cohort of 294 hysterectomy patients completed patient-reported outcomes preoperatively and six months postoperatively in Vancouver, Canada. Patient-reported outcomes measured pelvic health, sexual function, pain, and depression. Changes in health were compared with paired t-tests, and multi-variable regression analysis measured associations between patient and clinical factors with postoperative outcomes RESULTS: Many patients reported improvements in health. Unadjusted analysis found that 65% of participants reported less pelvic distress, 55% reported less pain, and 47% reported less depression symptoms postoperatively. Multivariable regression analysis found that poorer preoperative health was associated with poorer postoperative outcomes in all domains of health measured (p-value < 0.01). Postoperative pain scores were lower (less pain) by 0.78 among residents of the most affluent neighborhoods (p-value = 0.02) compared to those in less affluent neighborhoods. Postoperative depression scores were 1.58 points worse among participants with endometriosis (p-value = 0.03) and 1.02 points worse among participants having abdominal surgery (p-value = 0.02). CONCLUSION: Many participants reported improvements in pelvic symptoms, pain, and depression after hysterectomy. Lower socioeconomic status patients may be at risk for reporting higher pain after surgery, and endometriosis patients may report higher depression. Further investigation is needed to determine effective interventions for the higher postoperative pain observed in this study for residents of less affluent neighborhoods.

Outcomes of COVID-19 manuscripts submitted to the Canadian Journal of Anesthesia: a retrospective audit of author gender and person of colour status.

PURPOSE: We aimed to evaluate the representation of women and persons of colour (POC) authors of COVID-19 manuscripts submitted to, accepted in, and rejected from the Journal and to evaluate trends in their representation during the pandemic. METHODS: All COVID-19 manuscripts submitted to the Journal between 1 February 2020 and 30 April 2021 were included. Manuscript data were retrieved from Editorial Manager, and gender and POC status were obtained through: 1) e-mail communication with corresponding authors; 2) e-mail queries to other coauthors; 3) NamSor software, and 4) Internet searches. The data were described using percentages and summary statistics. A two-sample test of proportions was used for comparisons and trends were analyzed with linear regression. RESULTS: We identified 314 manuscripts (1,555 authors), 95 (461 authors) of which were accepted for publication. Of all authors, 515 (33%) were women, and women were the lead and senior authors of 101 (32%) and 69 (23%) manuscripts, respectively. There were no differences in women's representation as authors between accepted and rejected manuscripts. Overall, 923/1,555 (59%) authors were identified as POC, with a significantly lower proportion of POC authors among accepted vs rejected manuscripts (41%, 188/461 vs 67%, 735/1,094; difference, -26%; 95% CI, -32 to -21; P < 0.001). We did not observe significant trends in the proportion of women and POC authors over the study period. CONCLUSION: The proportion of women authors of COVID-19 manuscripts was lower than men's representation. Further research is required to determine the factors that account for the higher proportion of POC authors across rejected manuscripts.

RéSUMé: OBJECTIF: Nous avions pour objectif d'évaluer la représentation des femmes et des personnes de couleur ayant rédigé des manuscrits portant sur la COVID-19 soumis, acceptés et rejetés au Journal et d'évaluer les tendances concernant leur représentation pendant la pandémie. MéTHODE: Tous les manuscrits portant sur la COVID-19 soumis au Journal entre le 1er février 2020 et le 30 avril 2021 ont été inclus. Les données des manuscrits ont été extraites de la plateforme de gestion des manuscrits Editorial Manager, et le sexe et le statut de personne de couleur ont été obtenus par : 1) la communication par courrier électronique avec les auteurs et autrices correspondant·es; 2) des requêtes par courrier électronique envoyées à d'autres coautrices et coauteurs; 3) le logiciel NamSor, et 4) des recherches sur Internet. Les données ont été décrites à l'aide de pourcentages et de statistiques sommaires. Un test de proportions à deux échantillons a été utilisé pour les comparaisons et les tendances ont été analysées par régression linéaire. RéSULTATS: Nous avons identifié 314 manuscrits (1555 auteurs et autrices), dont 95 (461 autrices et auteurs) ont été acceptés pour publication. Parmi tou·tes les auteurs/autrices, 515 (33 %) étaient des femmes, et les femmes étaient les autrices principales et senior de 101 (32 %) et 69 (23 %) manuscrits, respectivement. Il n'y avait aucune différence dans la représentation des femmes en tant qu'autrices entre les manuscrits acceptés et rejetés. Dans l'ensemble, 923/1555 (59 %) auteurs et autrices ont été identifié·es comme étant des personnes de couleur, avec une proportion significativement plus faible d'autrices et d'auteurs de couleur parmi les manuscrits acceptés vs rejetés (41 %, 188/461 vs 67 %, 735/1094; différence, -26 %; IC 95 %, -32 à -21; P < 0,001). Nous n'avons pas observé de tendances significatives dans la proportion d'auteurs et d'autrices femmes et de couleur au cours de la période à l'étude. CONCLUSION: La proportion de femmes autrices de manuscrits sur la COVID-19 était inférieure à celle des hommes. D'autres recherches sont nécessaires pour déterminer les facteurs qui expliquent la plus grande proportion d'autrices et d'auteurs de couleur parmi les manuscrits rejetés.

Perioperative cortical hand stroke syndrome mimicking peripheral neuropathy: a case report.

PURPOSE: Timely diagnosis of perioperative stroke is challenging, and therapeutic interventions are infrequently offered. The cortical hand syndrome is a rare stroke presentation that results from infarction of the precentral gyrus leading to variable neurologic deficits mimicking peripheral nerve injuries, with no prior reports in the perioperative setting. To raise awareness of this complication among anesthesiologists, we present a case of cortical hand syndrome in a surgical patient initially suspected to have a peripheral neuropathy. CLINICAL FEATURES: A 68-yr-old male with multiple stroke risk factors underwent a nephroureterectomy under general anesthesia and thoracic epidural analgesia for urothelial carcinoma. The patient noted right-hand numbness and weakness to digits 3-5 immediately after surgery and notified his bedside nurse the following day. His symptoms were initially presumed to be a peripheral neuropathy secondary to surgical positioning. Computed tomography of the head the following day revealed an acute cortical infarct in the precentral gyrus consistent with cortical hand stroke syndrome. Subsequent neurologic consultation revealed additional subtle right-sided weakness. Further workup revealed moderate (60-80%) stenosis of the left carotid artery and he underwent a successful carotid endarterectomy one week later. His symptoms had mostly resolved six weeks later. CONCLUSION: Cortical hand stroke syndrome is a rare presentation of perioperative stroke that may be misdiagnosed as a peripheral neuropathy. Our case presentation highlights that perioperative stroke should be considered for patients presenting with neurologic deficits of the hand, particularly those with deficits in multiple peripheral nerve territories and stroke risk factors.

RéSUMé: OBJECTIF: Le diagnostic rapide de l'accident vasculaire cérébral (AVC) périopératoire est difficile, et les interventions thérapeutiques sont rarement proposées. Le syndrome de la main corticale est une présentation rare de l'AVC qui résulte d'un infarctus du gyrus précentral entraînant des déficits neurologiques variables imitant les lésions nerveuses périphériques, sans avoir été préalablement rapporté dans le cadre périopératoire. Afin de sensibiliser les anesthésiologistes à cette complication, nous présentons un cas de syndrome de la main corticale chez un patient chirurgical chez lequel une neuropathie périphérique était initialement suspectée. CARACTéRISTIQUES CLINIQUES: Un homme de 68 ans présentant de multiples facteurs de risque d'AVC a subi une néphro-urétérectomie sous anesthésie générale et une analgésie péridurale thoracique pour un carcinome urothélial. Le patient a remarqué un engourdissement et une faiblesse de la main droite du majeur à l'auriculaire immédiatement après la chirurgie et a avisé le personnel infirmier à son chevet le lendemain. On a d'abord présumé que ses symptômes indiquaient une neuropathie périphérique secondaire au positionnement chirurgical. La tomodensitométrie de la tête réalisée le lendemain a révélé un infarctus cortical aigu dans le gyrus précentral, compatible avec un syndrome d'AVC de la main corticale. Une consultation neurologique ultérieure a révélé une faiblesse subtile supplémentaire du côté droit. Un examen plus approfondi a révélé une sténose modérée (60 à 80 %) de l'artère carotide gauche et le patient a bénéficié d' une endartériectomie carotidienne réussie une semaine plus tard. Ses symptômes avaient pour la plupart disparu six semaines plus tard. CONCLUSION: Le syndrome de l'AVC de la main corticale est une présentation rare d'AVC périopératoire qui peut être diagnostiqué à tort comme une neuropathie périphérique. Notre présentation de cas souligne que l'AVC périopératoire devrait être envisagé chez les patient·es présentant des déficits neurologiques de la main, en particulier chez les personnes présentant des déficits dans plusieurs territoires nerveux périphériques et des facteurs de risque d'AVC.

Stroke in Patients with Left Ventricular Assist Devices.

BACKGROUND: Left ventricular assist devices (LVADs) are artificial pumps used in end-stage heart failure to support the circulatory system. These cardiac assist devices work in parallel to the heart, diverting blood from the left ventricle through an outflow graft and into the ascending aorta. LVADs have allowed patients with end-stage heart failure to live longer and with improved quality of life compared to best medical therapy alone. However, they are associated with significant risks related to both thrombosis and bleeding in this medically complex patient population. As LVADs continue to be used more widely, stroke neurologists need to become familiar with the unique physical exam and vascular imaging findings associated with this population. SUMMARY: Reported rates of LVAD-associated stroke at 2 years post-implantation range from 10 to 30%, which is significantly higher than in age-matched controls. There are approximately equal rates of ischemic and hemorrhagic strokes, and rates are highest during the peri-implantation period and in the first year of therapy. Risk factors associated with ischemic and hemorrhagic stroke in this cohort can be grouped into treatment-related factors, including specific devices and antithrombotic/anticoagulation strategy, and patient-related factors. Evidence for reperfusion therapy for acute stroke in this population is limited. Intravenous tissue plasminogen activator (IV-tPA) is often contraindicated as events may occur in the perioperative setting, or in the context of therapeutic anticoagulation. Endovascular therapy with successful recanalization is reported, but there is little experience documented in the published literature. Key messages: LVAD use is increasingly common. Given the high associated risks of stroke, neurologists will need to become increasingly familiar with an approach to assessment and therapy for LVAD patients with cerebrovascular issues.

Anesthetic consideations for endovascular treatment of acute ischemic stroke.

PURPOSE: The purpose of this Continuing Professional Development module is to provide information pertaining to anesthetic considerations and management of endovascular thrombectomy (EVT) for patients with acute ischemic stroke. PRINCIPAL FINDINGS: Acute ischemic stroke is a devastating neurologic disorder and timely intervention is key to a good neurologic outcome. This article provides an overview of three important concepts: pathophysiology and disease characteristics of acute ischemic stroke, and the procedural and anesthetic aspects of EVT. Key considerations include recognition of stroke symptoms, timing and urgency of intervention, procedural considerations for anesthesiologists, risks and benefits of different anesthetic techniques, and a summary of recent guidelines. In particular, current recommendations for blood pressure management in this setting are reviewed. CONCLUSIONS: Timely intervention for patients with acute ischemic stroke is of utmost importance. Endovascular thrombectomy is a minimally invasive procedure that has evolved over recent decades and improves outcomes for selected patients with ischemic stroke. Anesthesiologists should have a good understanding of potential complications and anesthetic options. Recent randomized trials have shown that both general anesthesia and sedation are associated with good outcomes; the anesthetic approach should be individualized and may vary by institution. Careful monitoring and maintenance of hemodynamic goals are critical, as is effective communication with the multidisciplinary team.

RéSUMé: OBJECTIF: L'objectif de ce module de développement professionnel continu est de fournir des informations sur les considérations anesthésiques et la prise en charge de la thrombectomie endovasculaire (TEV) chez les patients atteints d'AVC ischémique aigu. CONSTATATIONS PRINCIPALES: L'AVC ischémique aigu est un trouble neurologique dévastateur; une intervention rapide est la clé d'un bon devenir neurologique. Cet article donne un aperçu de plusieurs concepts importants : la physiopathologie et les caractéristiques pathologiques de l'AVC ischémique aigu, ainsi que les aspects procéduraux et anesthésiques de la TEV. Les principales considérations comprennent la reconnaissance des symptômes de l'AVC, le moment et l'urgence de l'intervention, les considérations procédurales pour les anesthésiologistes, les risques et les avantages des différentes techniques d'anesthésie, et un résumé des lignes directrices récentes. Plus spécifiquement, nous passerons en revue les recommandations actuelles pour la prise en charge de la pression artérielle dans un tel contexte. CONCLUSIONS: Une intervention rapide est essentielle pour les patients atteints d'AVC ischémique aigu. La thrombectomie endovasculaire est une procédure minimalement invasive qui a évolué au cours des dernières décennies et qui améliore les devenirs de certains patients atteints d'AVC ischémique. Les anesthésiologistes doivent avoir une bonne compréhension des complications potentielles et des options anesthésiques. Des études randomisées récentes ont montré que l'anesthésie générale et la sédation sont associées à de bons pronostics; l'approche anesthésique devrait être personnalisée et peut varier d'un établissement à l'autre. Un monitorage attentif et le maintien des cibles hémodynamiques sont essentiels, tout comme une communication efficace avec l'équipe multidisciplinaire.

Gender-based differences in physician payments within the fee-for-service system in Ontario: a retrospective, cross-sectional study.

BACKGROUND: Differences in physician income by gender have been described in numerous jurisdictions, but few studies have looked at a Canadian cohort with adjustment for confounders. In this study, we aimed to understand differences in fee-for-service payments to men and women physicians in Ontario. METHODS: We conducted a cross-sectional analysis of all Ontario physicians who submitted claims to the Ontario Health Insurance Plan (OHIP) in 2017. For each physician, we gathered demographic information from the College of Physicians and Surgeons of Ontario registry. We compared differences in physician claims between men and women in the entire cohort and within each specialty using multivariable linear regressions, controlling for length of practice, specialty and practice location. RESULTS: We identified a cohort of 30 167 physicians who submitted claims to OHIP in 2017, including 17 992 men and 12 175 women. When controlling for confounding variables in a linear mixed-effects regression model, annual physician claims were $93 930 (95% confidence interval $88 434 to $99 431) higher for men than for women. Women claimed 74% as much as men when adjusting for covariates. This discrepancy was present in nearly all specialty categories. Men claimed more than women throughout their careers, with the greatest gap 10-15 years into practice. INTERPRETATION: We found a gender gap in fee-for-service claims in Ontario, with women claiming less than men overall and in nearly every specialty. Further work is required to understand the root causes of the gender pay gap.

Women in anaesthesia: a scoping review.

Despite an increase in the proportion of women anaesthesiologists over time, women remain under-represented in academic and leadership positions, honour awards, and academic promotion. Current literature has identified several reasons for the observed gender disparity in anaesthesiology leadership and faculty positions, including unsupportive work environments, lack of mentorship, personal choices, childcare responsibilities, and active discrimination against women. A scoping review design was selected to examine the nature and extent of available research. Our review provides an overview of the literature that explores gender issues in anaesthesiology, identifies gaps in the literature, and appraises effective strategies to improve gender equity in anaesthesiology. We searched PubMed, MEDLINE, and EMBASE up to July 2019, and included 30 studies for analysis. Most reports used retrospective or survey methodologies. The review shows that women anaesthesiologists face gender biases in the work environment, are under-represented in various positions of leadership or influence, and as authors. Work-life demands may impose a challenge. Motivation and interest in career advancement of women anaesthesiologists have not been well studied. Several strategies have been proposed, ranging from an individual to administrative level, which may help anaesthesiologists achieve equal representation of women in the field.

Women anesthesiologists' journeys to academic leadership: a constructivist grounded theory-inspired study.

BACKGROUND: Women continue to be underrepresented in academic anesthesiology, especially in leadership positions. Possible reasons for this gender disparity include family responsibilities, inadequate mentorship, lack of desire for leadership, the leaky pipeline effect (i.e., attrition of women physicians over the course of their career trajectories), and discrimination. Our objective was to understand the lived experiences of Canadian anesthesiologists in leadership positions. METHODS: In this constructivist grounded theory-inspired study, we used purposeful sampling to identify women anesthesiologists in leadership positions at one Canadian institution. Each participant underwent a one-on-one semi-structured interview of 40-60 min in length, sampling until theoretical saturation was reached. We included questions about the participant's practice setting, influences on their career, and advice the participant would provide to other women in leadership. We used an iterative approach to theoretical sampling and data analysis. The audio-recorded semi-structured interviews were transcribed and coded. NVivo12 was used for open and axial coding, and cross-referencing. RESULTS: Eight women anesthesiologists were recruited and interviewed. Our iterative process identified four interconnected themes: difficulty internalizing a leadership identity, identifying systemic barriers and biases, dissonance between agentic traits and communal social gender roles, and mentorship as shaping lived experiences. Participants consistently expressed experiencing discrimination, articulated barriers related to family responsibilities and ingrained societal expectations, and discussed how typical leadership traits are applied differently to women and men. Women perceived themselves as more compassionate and communicative than men. Despite these traits, these women have expressed barriers to obtaining mentorship. CONCLUSION: We identified consistent interconnected themes among the experiences of our sample of women anesthesiologists in academic leadership and found that academic anesthesiology is a gendered profession as experienced by these women leaders. Further research should focus on strategies to remove barriers to participation in academic anesthesiology for women.

RéSUMé: CONTEXTE: Les femmes continuent d'être sous-représentées en anesthésiologie académique, et tout particulièrement dans les positions de leadership. Parmi les raisons expliquant cette disparité entre les sexes, citons les responsabilités familiales, un mentorat inadapté, le manque de désir de leadership, l'effet de tuyau percé (soit l'attrition des femmes médecins au cours de leur parcours professionnel) et la discrimination. Notre objectif était de comprendre les expériences vécues par les anesthésiologistes canadiennes en position de leadership. MéTHODE: Dans cette étude inspirée de la théorie ancrée constructiviste ('constructivist grounded theory'), nous avons utilisé un échantillonnage ciblé afin d'identifier les femmes anesthésiologistes en position de leadership dans un établissement canadien. Chaque participante a pris part à un entretien semi-structuré privé de 40-60 minutes, soit jusqu'à atteindre une saturation théorique. Nous avons inclus des questions concernant le cadre de pratique des participantes, les influences sur leur carrière, et les conseils qu'elles donneraient à d'autres femmes en position de leadership. Nous avons utilisé une approche itérative pour l'échantillonnage théorique et l'analyse de données. Un enregistrement sonore des entretiens semi-structurés a été réalisé pour être ensuite retranscrit et codé. Le progiciel NVivo12 a été utilisé pour le codage ouvert et axial ainsi que pour le référencement croisé. RéSULTATS: Huit femmes anesthésiologistes ont été recrutées et interviewées. Notre processus itératif nous a permis d'identifier quatre thèmes interconnectés : la difficulté d'internaliser une identité de leader, l'identification d'obstacles et de biais systémiques, la dissonance entre l'agentivité individuelle et les rôles de genre socialement construits, et le mentorat en tant que formatif des expériences vécues. Les participantes ont toutes exprimé ressentir de la discrimination, elles ont articulé des obstacles liés aux responsabilités familiales et aux attentes sociétales enracinées, et ont expliqué comment les caractéristiques typiques de leadership étaient appliquées différemment selon le sexe. Les femmes se percevaient comme étant plus empathiques et communicatives que les hommes. Malgré ces traits de caractère, ces femmes ont exprimé qu'il existait des obstacles à l'obtention de mentorat. CONCLUSION: Nous avons identifié plusieurs thèmes interconnectés récurrents parmi les expériences de notre échantillonnage de femmes anesthésiologistes dans des positions de leadership académique et observé que l'anesthésiologie en milieu académique est une profession genrée, comme l'ont ressenti ces femmes leaders. Les recherches futures devraient mettre l'accent sur des stratégies visant à déjouer les obstacles à la participation des femmes en anesthésiologie académique.

Representation of women amongst speakers at the Canadian Anesthesiologists' Society annual meeting: a retrospective analysis from 2007 to 2019.

PURPOSE: Despite an increase in the proportion of women entering the field of anesthesiology, women remain underrepresented in academic and leadership positions. Speaking at national and international conferences is an important component of academic visibility and promotion. To date, the gender representation of speakers at the Canadian Anesthesiologists' Society (CAS) annual meeting has not been examined. METHODS: We conducted a retrospective analysis of the representation of women amongst speakers at the CAS annual meeting between 2007 and 2019, inclusively. We also examined the representation of women in different subspecialty subject area symposia at each CAS annual meeting, and the gender composition of meeting symposia panels (i.e., groups of two or more speakers in a session) at the meeting. RESULTS: Overall, 28.5% (358/1,256) of speaker slots included women, similar to their representation in Canadian clinical anesthesiology over the study period (26.7%), and increasing significantly over the study period. Women were more highly represented as obstetric anesthesia speakers at the CAS annual meetings, with lower representation in cardiothoracic anesthesia, transplant anesthesia, and critical care symposia. Of the 311 meeting symposia, 146 (46%) were composed of all men speakers. CONCLUSION: The representation of women speakers at the CAS annual meeting was similar to the representation of women in the anesthesiology workforce in Canada over the study period. Gender representation varied widely by subspecialty symposia, subject area, and women were absent from nearly half of all symposia at the CAS annual meetings, which are potential areas of future investigation and intervention.

Knowledge and perceptions about perioperative stroke: a cross-sectional survey of patients scheduled for non-neurologic and non-cardiac surgery.

PURPOSE: Perioperative stroke is associated with significant morbidity and mortality yet patients may not be aware of their risk or receive appropriate counselling. Our objectives were to 1) compare patient's perceived vs calculated risk of stroke; 2) determine level of worry; and 3) assess prior discussion about perioperative stroke risk amongst elective patients undergoing non-cardiac, non-neurologic surgery. METHODS: Over a consecutive four-week period, surveys were distributed at two pre-anesthetic clinics to adult patients scheduled for non-cardiac, non-neurologic surgery. The survey included questions about demographics, perioperative stroke risk factors, patient perception of their quantitative and qualitative stroke risk, level of worry about stroke, and risk discussions. We identified independent predictors of risk underestimation amongst medium- and high-risk patients. RESULTS: Six hundred patients completed the survey (response rate 78%). Of these, 479, 104, and 15 patients were classified as low-, medium-, and high-risk, respectively (with two patients missing this data point). Most medium- (86%) and high-risk (80%) patients did not identify their elevated risk. Amongst medium- and high-risk patients, independent predictors of risk underestimation were lower education and absence of kidney disease. Medium- and high-risk patients were more worried than low-risk patients about perioperative stroke (median [interquartile range] visual analogue scale score 2 [0.5-4] vs 1 [0-2], P = 0.001). Fewer than half of patients had discussed perioperative stroke previously (40%, 23%, and 12% of high-, medium-, and low-risk patients, respectively). CONCLUSIONS: Patients at higher risk of stroke frequently underestimate their risk of perioperative stroke. The majority of patients had not discussed perioperative stroke prior to anesthetic consultation.

Guidelines to the Practice of Anesthesia - Revised Edition 2020.

OVERVIEW: The Guidelines to the Practice of Anesthesia Revised Edition 2020 (the Guidelines) were prepared by the Canadian Anesthesiologists' Society (CAS), which reserves the right to determine their publication and distribution. The Guidelines are subject to revision and updated versions are published annually. The Guidelines to the Practice of Anesthesia Revised Edition 2020 supersedes all previously published versions of this document. Although the CAS encourages Canadian anesthesiologists to adhere to its practice guidelines to ensure high-quality patient care, the CAS cannot guarantee any specific patient outcome. Anesthesiologists should exercise their own professional judgement in determining the proper course of action for any patient's circumstances. The CAS assumes no responsibility or liability for any error or omission arising from the use of any information contained in its Guidelines to the Practice of Anesthesia.

Representation of female authors in the Canadian Journal of Anesthesia: a retrospective analysis of articles between 1954 and 2017.

PURPOSE: Females remain under-represented in academic anesthesiology. Our objectives were to investigate gender differences over time in the first and last authors of published articles as well as corresponding citation rates in the Canadian Journal of Anesthesia (CJA). METHODS: We conducted a cross-sectional, retrospective analysis of first and last authors' gender from editorials and original articles published in the CJA in a sample of one calendar year of each decade between 1954 to 2017. We analyzed the relationships between author gender, year of publication, article type, and number of citations. RESULTS: Out of 639 articles identified, 542 (85%) were original investigations and 97 (15%) were editorials. Where gender could be confidently identified, the majority (461/571, 81%) of first authors were male. Although there was an increase in the proportion of female first authors over time, this increase was outpaced by the overall increase in female anesthesiologists in Canada. Original articles received more citations and were more likely to have a female first author than editorial articles were. An original article with a female first author resulted in 0.34 (95% confidence interval, 0.28 to 0.39; P < 0.001) more citations per article than a male first author when adjusting for year of publication. CONCLUSIONS: Our study shows that, despite a slow increase over time, female authors are under-represented relative to male authors in the CJA and relative to the changing demographics of anesthesiologists in Canada. The reasons for this disparity are multifactorial and further research is needed to identify effective solutions.

RéSUMé: OBJECTIF: Les femmes restent sous-représentées dans le monde de l'anesthésiologie universitaire. Nos objectifs étaient d'étudier l'évolution des premiers et derniers auteurs en fonction du sexe au fil des années dans les articles publiés ainsi que les taux correspondants de citation dans le Journal canadien d'anesthésie (CJA). MéTHODES: Nous avons mené une analyse transversale rétrospective du sexe des premiers et derniers auteurs des éditoriaux et des articles originaux publiés dans le CJA dans un échantillon d'une année civile pour chaque décennie entre 1954 et 2017. Nous avons analysé les rapports entre le sexe des auteurs, l'année de publication, le type d'articles et le nombre de citations. RéSULTATS: Sur 639 articles identifiés, 542 (85 %) étaient des recherches originales et 97 (15 %) étaient des éditoriaux. Lorsque le sexe a pu être identifié avec certitude, la majorité des premiers auteurs (461/571, 81 %) étaient des hommes. Bien qu'il y ait eu une augmentation du pourcentage de femmes premières auteures au fil du temps, cette augmentation n'a pas suivi la progression du nombre global des femmes anesthésiologistes au Canada. Les articles originaux ont été cités plus souvent et ont été plus susceptibles d'avoir un premier auteur féminin que les éditoriaux. Après ajustement pour l'année de publication, un article original dont le premier auteur était une femme comptait 0,34 (intervalle de confiance à 95 %, 0,28 à 0,39; P < 0,001) fois plus de citations que lorsque le premier auteur était un homme. CONCLUSIONS: Notre étude montre que, malgré une lente augmentation avec les années, les femmes auteures sont sous-représentées par rapport à leurs collègues masculins dans le CJA et par rapport aux changements démographiques de l'anesthésiologie au Canada. Les raisons de cette disparité sont multifactorielles et d'autres recherches sont nécessaires pour trouver des solutions efficaces.
