Surgical Cancellations and Postponements by Surgeon and Patient Sex: A Retrospective Cohort Study in Alberta, Canada.

OBJECTIVE: The objective of this work was to estimate the association between surgeon sex with surgical postponements or cancellations. SUMMARY BACKGROUND DATA: Female surgeons receive lower hourly, per patient, and total compensation than their male colleagues. Bias in the decision to postpone or cancel surgical cases may contribute to compensation inequality, since this results in unpaid surgeon time. METHODS: This retrospective cohort study used administrative health data to identify surgeries performed at four hospitals in Calgary, Alberta, Canada that were cancelled or postponed due to surgeon/operating room overbooking or to accommodate an emergency case between April 1, 2015, and March 31, 2020. Surgeries performed in dedicated operating or procedure rooms (e.g., bronchoscopy, cardiac surgery, etc.) were excluded. The exposure of interest was surgeon sex, identified by matching their name to the provincial regulatory body record of self-identified sex, which allowed for selection between female and male only during the time of this study. RESULTS: There were 214,832 eligible surgical cases, of which 1,481 and 2,473 were postponed or cancelled due to overbooking and to accommodate an emergency, respectively. After adjusting for surgical specialty, whether the procedure was a day case, and for patient sex, female surgeons were more likely to be cancelled or postponed to accommodate an emergency case compared to male surgeons (odds ratio [OR] 1.21, 95% confidence interval [CI] 1.05-1.38). CONCLUSION: There may be sex-bias in the decision about which surgical cases to postpone or cancel to accommodate emergency surgeries in our setting. This bias may contribute to compensation inequality in a fee-for-service setting.

Implementation of a surgical site infection prevention bundle in gynecologic oncology patients: An enhanced recovery after surgery initiative.

OBJECTIVE: To evaluate the clinical outcomes pre- and post-implementation of an evidence-informed surgical site infection prevention bundle (SSIPB) in gynecologic oncology patients within an Enhanced Recovery After Surgery (ERAS) care pathway. METHODS: Patients undergoing laparotomy for a gynecologic oncology surgery between January-June 2017 (pre-SSIPB) and between January 2018-December 2020 (post-SSIPB) were compared using t-tests and chi-square. Patient characteristics, surgical factors, and ERAS process measures and outcomes were abstracted from the ERAS® Interactive Audit System (EIAS). The primary outcomes were incidence of surgical site infections (SSI) during post-operative hospital admission and at 30-days post-surgery. Secondary outcomes included total postoperative infections, length of stay, and any surgical complications. Multivariate models were used to adjust for potential confounding factors. RESULTS: Patient and surgical characteristics were similar in the pre- and post-implementation periods. Evaluation of implementation suggested that preoperative and intraoperative components of the intervention were most consistently used. Infectious complications within 30 days of surgery decreased from 42.1% to 24.4% after implementation of the SSIPB (p < 0.001), including reductions in wound infections (17.0% to 10.8%, p = 0.02), urinary tract infections (UTI) (12.7% to 4.5%, p < 0.001), and intra-abdominal abscesses (5.4% to 2.5%, p = 0.05). These reductions were associated with a decrease in median length of stay from 3 to 2 days (p = 0.001). In multivariate analysis, these SSI reductions remained statistically significant after adjustment for potential confounders. CONCLUSION: Implementation of SSIPB was associated with a reduction in SSIs and infectious complications, as well as a shorter length of stay in gynecologic oncology patients.

A logic framework for addressing medical racism in academic medicine: an analysis of qualitative data.

BACKGROUND: Despite decades of anti-racism and equity, diversity, and inclusion (EDI) interventions in academic medicine, medical racism continues to harm patients and healthcare providers. We sought to deeply explore experiences and beliefs about medical racism among academic clinicians to understand the drivers of persistent medical racism and to inform intervention design. METHODS: We interviewed academically-affiliated clinicians with any racial identity from the Departments of Family Medicine, Cardiac Sciences, Emergency Medicine, and Medicine to understand their experiences and perceptions of medical racism. We performed thematic content analysis of semi-structured interview data to understand the barriers and facilitators of ongoing medical racism. Based on participant narratives, we developed a logic framework that demonstrates the necessary steps in the process of addressing racism using if/then logic. This framework was then applied to all narratives and the barriers to addressing medical racism were aligned with each step in the logic framework. Proposed interventions, as suggested by participants or study team members and/or identified in the literature, were matched to these identified barriers to addressing racism. RESULTS: Participant narratives of their experiences of medical racism demonstrated multiple barriers to addressing racism, such as a perceived lack of empathy from white colleagues. Few potential facilitators to addressing racism were also identified, including shared language to understand racism. The logic framework suggested that addressing racism requires individuals to understand, recognize, name, and confront medical racism. CONCLUSIONS: Organizations can use this logic framework to understand their local context and select targeted anti-racism or EDI interventions. Theory-informed approaches to medical racism may be more effective than interventions that do not address local barriers or facilitators for persistent medical racism.

Association of Kidney Function With Major Postoperative Events After Noncardiac Ambulatory Surgeries: A Population-Based Cohort Study.

OBJECTIVE: The aim of this study was to estimate the association between estimated glomerular filtration rate (eGFR) and acute myocardial infarction (AMI) or death after ambulatory noncardiac surgery. SUMMARY BACKGROUND DATA: People with chronic kidney disease (CKD) commonly undergo surgical procedures. Although most are performed in an ambulatory setting, the risk of major perioperative outcomes after ambulatory surgery for people with CKD is unknown. METHODS: In this retrospective population-based cohort study using administrative health data from Alberta, Canada, we included adults with measured preoperative kidney function undergoing ambulatory noncardiac surgery between April 1, 2005 and February 28, 2017. Participants were categorized into 6 eGFR categories (in mL/min/1.73m 2 )of ≥60 (G1-2), 45 to 59 (G3a), 30 to 44 (G3b), 15 to 29 (G4), <15 not receiving dialysis (G5ND), and those receiving chronic dialysis (G5D). The odds of AMI or death within 30 days of surgery were estimated using multivariable generalized estimating equation models. RESULTS: We identified 543,160 procedures in 323,521 people with a median age of 66 years (IQR 56-76); 52% were female. Overall, 2338 people (0.7%) died or had an AMI within 30 days of surgery. Compared with the G1-2 category, the adjusted odds ratio of death or AMI increased from 1.1 (95% confidence interval: 1.0-1.3) for G3a to 3.1 (2.6-3.6) for G5D. Emergency Department and Urgent Care Center visits within 30 days were frequent (17%), though similar across eGFR categories. CONCLUSIONS: Ambulatory surgery was associated with a low risk of major postoperative events. This risk was higher for people with CKD, which may inform their perioperative shared decision-making and management.

Experiences and Perceptions of Racism and Sexism Among Alberta Physicians: Quantitative Results and Framework Analysis of a Cross-Sectional Survey.

BACKGROUND: The prevalence of harassment and discrimination in medicine differs by race and gender. The current evidence is limited by a lack of intersectional analysis. OBJECTIVE: To evaluate the experiences and perceptions of harassment and discrimination in medicine across physicians stratified by self-identified race and gender identity. DESIGN: Quantitative and framework analysis of results from a cross-sectional survey study. PARTICIPANTS: Practicing physicians in the province of Alberta, Canada (n=11,688). MAIN MEASURES: Participants completed an instrument adapted from the Culture Conducive to Women's Academic Success to capture the perceived culture toward self-identified racial minority physicians (Black, Indigenous, and People of Color (BIPOC)), indicated their perception of gender inequity in medicine using Likert responses to questions about common experiences, and were asked about experiences of reporting harassment or discrimination. Participants were also able to provide open text comments. KEY RESULTS: Among the 1087 respondents (9.3% response rate), 73.5% reported experiencing workplace harassment or discrimination. These experiences were least common among White cisgender men and most common among BIPOC cisgender women (52.4% and 85.4% respectively, p<0.00001). Cisgender men perceived greater gender equity than cisgender women physicians, and White cisgender men physicians perceived greatest racial equity. Participant groups reporting the greatest prevalence of harassment and discrimination experiences were the least likely to know where to report harassment, and less than a quarter of physicians (23.8%) who had reported harassment or discrimination were satisfied with the outcome. Framework analysis of open text responses identified key types of barriers to addressing racism, including denial of racism and greater concern about other forms of discrimination and harassment. CONCLUSIONS: Our results document the prevalence of harassment and discrimination by intersectional identities of race and gender. Incongruent perceptions and experiences may act as a barrier to preventing and addressing harassment and discrimination in the Canadian medical workplace.

Perioperative management for people with kidney failure receiving dialysis: A scoping review.

BACKGROUND: People with kidney failure receiving dialysis (CKD-G5D) are more likely to undergo surgery and experience poorer postoperative outcomes than those without kidney failure. In this scoping review, we aimed to systematically identify and summarize perioperative strategies, protocols, pathways, and interventions that have been studied or implemented for people with CKD-G5D. METHODS: We searched MEDLINE, EMBASE, CINAHL Plus, Cochrane Database of Systematic Reviews, and Cochrane Controlled Trials registry (inception to February 2020), in addition to an extensive grey literature search, for sources that reported on a perioperative strategy to guide management for people with CKD-G5D. We summarized the overall study characteristics and perioperative management strategies and identified evidence gaps based on surgery type and perioperative domain. Publication trends over time were assessed, stratified by surgery type and study design. RESULTS: We included 183 studies; the most common study design was a randomized controlled trial (27%), with 67% of publications focused on either kidney transplantation or dialysis vascular access. Transplant-related studies often focused on fluid and volume management strategies and risk stratification, whereas dialysis vascular access studies focused most often on imaging. The number of publications increased over time, across all surgery types, though driven by non-randomized study designs. CONCLUSIONS: Despite many current gaps in perioperative research for patients with CKD-G5D, evidence generation supporting perioperative management is increasing, with recent growth driven primarily by non-randomized studies. Our review may inform organization of evidence-based strategies into perioperative care pathways where evidence is available while also highlighting gaps that future perioperative research can address.

Prediction of major postoperative events after non-cardiac surgery for people with kidney failure: derivation and internal validation of risk models.

BACKGROUND: People with kidney failure often require surgery and experience worse postoperative outcomes compared to the general population, but existing risk prediction tools have excluded those with kidney failure during development or exhibit poor performance. Our objective was to derive, internally validate, and estimate the clinical utility of risk prediction models for people with kidney failure undergoing non-cardiac surgery. DESIGN, SETTING, PARTICIPANTS, AND MEASURES: This study involved derivation and internal validation of prognostic risk prediction models using a retrospective, population-based cohort. We identified adults from Alberta, Canada with pre-existing kidney failure (estimated glomerular filtration rate [eGFR] < 15 mL/min/1.73m2 or receipt of maintenance dialysis) undergoing non-cardiac surgery between 2005-2019. Three nested prognostic risk prediction models were assembled using clinical and logistical rationale. Model 1 included age, sex, dialysis modality, surgery type and setting. Model 2 added comorbidities, and Model 3 added preoperative hemoglobin and albumin. Death or major cardiac events (acute myocardial infarction or nonfatal ventricular arrhythmia) within 30 days after surgery were modelled using logistic regression models. RESULTS: The development cohort included 38,541 surgeries, with 1,204 outcomes (after 3.1% of surgeries); 61% were performed in males, the median age was 64 years (interquartile range [IQR]: 53, 73), and 61% were receiving hemodialysis at the time of surgery. All three internally validated models performed well, with c-statistics ranging from 0.783 (95% Confidence Interval [CI]: 0.770, 0.797) for Model 1 to 0.818 (95%CI: 0.803, 0.826) for Model 3. Calibration slopes and intercepts were excellent for all models, though Models 2 and 3 demonstrated improvement in net reclassification. Decision curve analysis estimated that use of any model to guide perioperative interventions such as cardiac monitoring would result in potential net benefit over default strategies. CONCLUSIONS: We developed and internally validated three novel models to predict major clinical events for people with kidney failure having surgery. Models including comorbidities and laboratory variables showed improved accuracy of risk stratification and provided the greatest potential net benefit for guiding perioperative decisions. Once externally validated, these models may inform perioperative shared decision making and risk-guided strategies for this population.

Strategies for intraoperative glucose management: a scoping review.

PURPOSE: Perioperative hyperglycemia is associated with adverse outcomes for patients with and without diabetes. Guidelines and published protocols for intraoperative glycemic management have substantial variation in their recommendations. We sought to characterize the current evidence-guiding intraoperative glycemic management in a scoping review. SOURCES: Our search strategy included MEDLINE (Ovid and EBSCO), PubMed, PubMed Central, EMBASE, CINAHL, Cochrane Library, SciVerse Scopus, and Web of Science and a gray literature search of Google, Google Scholar, hand searching of the reference lists of included articles, OAISter, institutional protocols, and ClinicalTrails.gov. PRINCIPAL FINDINGS: We identified 41 articles that met our inclusion criteria, 24 of which were original research studies. Outcomes and exposures were defined heterogeneously across studies, which limited comparison and synthesis. Investigators often created arbitrary and differing categories of glucose values rather than analyzing glucose as a continuous variable, which limited our ability to combine results from different studies. In addition, the study populations and surgery types also varied considerably, with few studies performed during day surgeries and specific surgical disciplines. Study populations often included more than one type of surgery, indication, and urgency that were expected to have varying physiologic and inflammatory responses. Combining low- and high-risk patients in the same study population may obscure the harms or benefits of intraoperative glycemic management for high-risk procedures or patients. CONCLUSION: Future studies examining intraoperative glycemic management should carefully consider the study population, surgical characteristics, and pre- and postoperative management of hyperglycemia.

RéSUMé: OBJECTIF: L'hyperglycémie périopératoire est associée à des effets indésirables chez les patients diabétiques et non diabétiques. Les lignes directrices et les protocoles publiés pour la prise en charge glycémique peropératoire présentent des variations substantielles dans leurs recommandations. Nous avons cherché à caractériser les données probantes actuelles guidant la prise en charge glycémique peropératoire dans une étude de portée. SOURCES: Notre stratégie de recherche a inclus les bases de données MEDLINE (Ovid et EBSCO), PubMed, PubMed Central, EMBASE, CINAHL, Cochrane Library, SciVerse Scopus et Web of Science, ainsi qu'une recherche documentaire grise sur Google, Google Scholar, la recherche manuelle des listes de référence des articles inclus, OAISter, les protocoles institutionnels et ClinicalTrials.gov. CONSTATATIONS PRINCIPALES: Nous avons identifié 41 articles qui répondaient à nos critères d'inclusion, dont 24 étaient des études de recherche originales. Les critères d'évaluation et les expositions étaient définis de manière hétérogène d'une étude à l'autre, ce qui a limité la comparaison et la synthèse. Les chercheurs ont souvent créé des catégories arbitraires et différentes de valeurs glycémiques plutôt que d'analyser la glycémie comme une variable continue, ce qui a limité notre capacité à combiner les résultats de différentes études. En outre, les populations étudiées et les types de chirurgie variaient également considérablement, avec peu d'études réalisées lors de chirurgies ambulatoires et dans certaines disciplines chirurgicales spécifiques. Les populations étudiées comprenaient souvent plus d'un type de chirurgie, d'indication et d'urgence, pour lesquelles des réponses physiologiques et inflammatoires variables étaient attendues. La combinaison de patients à faible et à haut risque dans la même population d'étude a pu masquer les inconvénients ou les avantages d'une prise en charge glycémique peropératoire pour les interventions ou les patients à haut risque. CONCLUSION: Les études futures portant sur la prise en charge glycémique peropératoire devraient examiner attentivement la population étudiée, les caractéristiques chirurgicales et la prise en charge pré- et postopératoire de l'hyperglycémie.

The contribution of undergraduate medical education dress codes to systemic discrimination: A critical policy analysis.

PURPOSE: Critical review of institutional policies is necessary to identify and eliminate structural discrimination in medical schools. Dress code policies are well known to facilitate discrimination in other settings. METHODS: In this critical policy analysis, the authors used qualitative inquiry guided by feminist critical policy analysis (FCPA) and critical race feminism (CRF) frameworks to understand how Canadian undergraduate medical school dress code policies may contribute to discrimination and a hostile culture for marginalised groups. Dress code policies were obtained from 14 of 17 Canadian medical schools in September 2021. Deductive content analysis of dress codes was performed independently and in parallel by all four members of a racially diverse study team using Edwards and Marshalls' established framework for applying FCPA and CRF to dress code policy statements. Inductive content analysis was used to classify statements that fell outside this framework. Using a historical and contemporary legal understanding of how dress code policies have been used to discriminate against marginalised groups, the authors analysed how recommendations or restrictions may contribute to discrimination of marginalised medical students. RESULTS: Fourteen dress code policies were analysed. Overall, there were five feminine-coded restrictions for every one masculine-coded restriction (n = 77/213 and n = 16/213, respectively). Some policies prohibited feminine-coded items (e.g. perfumes and bracelets) while specifically allowing masculine-coded items (e.g. cologne and watches). A discourse of 'professionalism' based on patient preferences prioritised Eurocentric patriarchal norms for appearance, potentially penalising racially and culturally diverse students. Most policies did not include a policy for appeals or accommodations. CONCLUSION: Canadian undergraduate medical school dress code policies overregulate women and gender, racially and culturally diverse students by explicitly and implicitly enforcing white patriarchal social norms. Administrators should apply best practices to these policies to avoid discrimination and a hostile culture to marginalised groups.

Anti-Indigenous bias of medical school applicants: a cross-sectional study.

BACKGROUND: Structural and interpersonal anti-Indigenous racism is prevalent in Canadian healthcare. The Truth and Reconciliation Commission calls on medical schools to address anti-Indigenous bias in students. We measured the prevalence of interpersonal anti-Indigenous bias among medical school applicants to understand how the medical school selection process selects for or against students with high levels of bias. METHODS: All applicants to a single university in the 2020-2021 admissions cycle were invited to participate. Explicit anti-Indigenous bias was measured using two sliding scale thermometers. The first asked how participants felt about Indigenous people (from 0, indicating 'cold/unfavourable' to 100, indicating 'warm/favourable') and the second asked whether participants preferred white (scored 100) or Indigenous people (scored 0). Participants then completed an implicit association test examining preferences for European or Indigenous faces (negative time latencies suggest preference for European faces). Explicit and implicit anti-Indigenous biases were compared by applicant demographics (including gender and racial identity), application status (offered an interview, offered admission, accepted a position), and compared to undergraduate medical and mathematics students. RESULTS: There were 595 applicant respondents (32.4% response rate, 64.2% cisgender women, 55.3% white). Applicants felt warmly toward Indigenous people (median 96 (IQR 80-100)), had no explicit preference for white or Indigenous people (median 50 (IQR 37-55), and had mild implicit preference for European faces (- 0.22 ms (IQR -0.54, 0.08 ms)). There were demographic differences associated with measures of explicit and implicit bias. Applicants who were offered admission had warmer feelings toward Indigenous people and greater preference for Indigenous people compared to those were not successful. CONCLUSIONS: Medical school applicants did not have strong interpersonal explicit and implicit anti-Indigenous biases. Outlier participants with strong biases were not offered interviews or admission to medical school.

Estimated GFR and Incidence of Major Surgery: A Population-Based Cohort Study.

RATIONALE & OBJECTIVE: Kidney disease is associated with an increased risk for postoperative morbidity and mortality. However, the incidence of major surgery on a population level is unknown. We aimed to determine the incidence of major surgery by level of kidney function. STUDY DESIGN: Retrospective cohort study with entry from January 1, 2008, through December 31, 2009, and outcome surveillance from January 1, 2010, through December 31, 2016. SETTING & PARTICIPANTS: Population-based study using administrative health data from Alberta, Canada; adults with an outpatient serum creatinine measurement or receiving maintenance dialysis formed the study cohort. EXPOSURE: Participants were categorized into 6 estimated glomerular filtration rate (eGFR) categories: ≥60 (G1-G2), 45 to 59 (G3a), 30 to 44 (G3b), 15 to 29 (G4), and<15mL/min/1.73m2 with (G5D) and without (G5) dialysis. eGFR was examined as a time-varying exposure based on means of measurements within 3-month ascertainment periods throughout the study period. OUTCOME: Major surgery defined as surgery requiring admission to the hospital for at least 24 hours. ANALYTICAL APPROACH: Incidence rates (IRs) for overall major surgery were estimated using quasi-Poisson regression and adjusted for age, sex, income, location of residence, albuminuria, and Charlson comorbid conditions. Age- and sex-stratified IRs of 13 surgery subtypes were also estimated. RESULTS: 1,455,512 cohort participants were followed up for a median of 7.0 (IQR, 5.3) years, during which time 241,989 (16.6%) underwent a major surgery. Age and sex modified the relationship between eGFR and incidence of surgery. Men younger than 65 years receiving maintenance dialysis experienced the highest rates of major surgery, with an adjusted IR of 243.8 (95% CI, 179.8-330.6) per 1,000 person-years. There was a consistent trend of increasing surgery rates at lower eGFRs for most subtypes of surgery. LIMITATIONS: Outpatient preoperative serum creatinine measurement was necessary for inclusion and outpatient surgical procedures were not included. CONCLUSIONS: People with reduced eGFR have a significantly higher incidence of major surgery compared with those with normal eGFR, and age and sex modify this increased risk. This study informs our understanding of how surgical burden changes with differing levels of kidney function.

Challenges to Navigating Pregnancy and Parenthood for Physician Parents: a Framework Analysis of Qualitative Data.

BACKGROUND: Some gender-based disparities in medicine may relate to pregnancy and parenthood. An understanding of the challenges faced by pregnant physicians and physician parents is needed to design policies and interventions to reduce these disparities. OBJECTIVE: Our objective was to characterize work-related barriers related to pregnancy and parenthood described by physicians. DESIGN: We performed framework analysis of qualitative data collected through individual, semi-structured interviews between May and October 2018. Data related to pregnancy or parenthood were organized chronologically to understand barriers throughout the process of pregnancy, planning a parental leave, taking a parental leave, returning from parental leave, and parenting as a physician. PARTICIPANTS: Physician faculty members of all genders, including parents and non-parents, from a single department at a large academic medical school in Canada were invited to participate in a department-wide study broadly exploring gender equity. APPROACH: Thematic analysis guided by constructivism. KEY RESULTS: Twenty-eight physicians were interviewed (7.2% of eligible physicians), including 22 women and 6 men, of which 18 were parents (15 mothers and 3 fathers). Common barriers included a lack of systems-level guidelines for pregnancy and parental leave, inconsistent workplace accommodations for pregnant physicians, a lack of guidance and support for planning parental leaves, and difficulties obtaining clinical coverage for parental leave. Without systems-level guidance, participants had to individually navigate challenges and resolve these difficulties, including negotiating with their leadership for benefits. This led to stress, wasted time and effort, and raised questions about fairness within the department. CONCLUSIONS: Physician parents face unique challenges navigating institutional policies as well as planning and taking parental leave. Systems-level interventions such as policies for pregnancy, parental leave, and return to work are needed to address barriers experienced by physician parents.

The Gender of COVID-19 Experts in Newspaper Articles: a Descriptive Cross-Sectional Study.

BACKGROUND: Pre-existing gender-based disparities in academia may have worsened during the COVID-19 pandemic. Being cited as an expert source in newspaper articles about COVID-19 may increase an individual's research or leadership profile. In addition, visibility in a newspaper article is an important component of representation in academia. OBJECTIVE: To determine whether women were underrepresented as COVID-19 expert sources in print newspapers in the USA. DESIGN: We undertook a cross-sectional study of English-language newspaper articles that addressed the COVID-19 pandemic and that were published in the top 10 most widely read newspapers in the USA between April 1 and April 15, 2020. MAIN MEASURES: We extracted the names of all people cited as expert sources and categorized the gender of each expert source based on pronoun usage within the article or on a business, university, or organization website. The professional role of each expert was assigned based on their description in the article. KEY RESULTS: Of 2297 expert sources identified, 35.9% (95% confidence interval [CI] 33.9-37.8%; n = 824) were women and 63.7% were men (95% CI 61.8-65.7%; n = 1464). This result was similar when considering unique experts in each newspaper and for all included newspapers; of the 1738 unique experts per newspaper, 34.6% were women (95% CI 32.3-36.8%; n = 601), and of the 1593 unique experts in all newspapers, 36.5% were women (95% CI 34.1-38.9%; n = 581). Of articles with multiple experts referenced (n = 374), 102 cited only men experts (27.3%) and 44 cited only women experts (11.8%). Women were underrepresented as experts as Healthcare Workers and Professionals, Non-STEM Experts, Public Health Leaders, and STEM Scientists. There were no differences in the proportion of women experts between newspapers or between different regions of the USA. CONCLUSIONS: Altogether, our findings support that men academics outnumber women as COVID-19 experts in newspaper articles.

Description of a Multi-faceted COVID-19 Pandemic Physician Workforce Plan at a Multi-site Academic Health System.

BACKGROUND: The evolving COVID-19 pandemic has and continues to present a threat to health system capacity. Rapidly expanding an existing acute care physician workforce is critical to pandemic response planning in large urban academic health systems. INTERVENTION: The Medical Emergency-Pandemic Operations Command (MEOC)-a multi-specialty team of physicians, operational leaders, and support staff within an academic Department of Medicine in Calgary, Canada-partnered with its provincial health system to rapidly develop a comprehensive, scalable pandemic physician workforce plan for non-ventilated inpatients with COVID-19 across multiple hospitals. The MEOC Pandemic Plan comprised seven components, each with unique structure and processes. METHODS: In this manuscript, we describe MEOC's Pandemic Plan that was designed and implemented from March to May 2020 and re-escalated in October 2020. We report on the plan's structure and process, early implementation outcomes, and unforeseen challenges. Data sources included MEOC documents, health system, public health, and physician engagement implementation data. KEY RESULTS: From March 5 to October 26, 2020, 427 patients were admitted to COVID-19 units in Calgary hospitals. In the initial implementation period (March-May 2020), MEOC communications reached over 2500 physicians, leading to 1446 physicians volunteering to provide care on COVID-19 units. Of these, 234 physicians signed up for hospital shifts, and 227 physicians received in-person personal protective equipment simulation training. Ninety-three physicians were deployed on COVID-19 units at four large acute care hospitals. The resurgence of cases in September 2020 has prompted re-escalation including re-activation of COVID-19 units. CONCLUSIONS: MEOC leveraged an academic health system partnership to rapidly design, implement, and refine a comprehensive, scalable COVID-19 acute care physician workforce plan whose components are readily applicable across jurisdictions or healthcare crises. This description may guide other institutions responding to COVID-19 and future health emergencies.

Mortality and cardiovascular events in adults with kidney failure after major non-cardiac surgery: a population-based cohort study.

BACKGROUND: People with kidney failure have a high incidence of major surgery, though the risk of perioperative outcomes at a population-level is unknown. Our objective was to estimate the proportion of people with kidney failure that experience acute myocardial infarction (AMI) or death within 30 days of major non-cardiac surgery, based on surgery type. METHODS: In this retrospective population-based cohort study, we used administrative health data to identify adults from Alberta, Canada with major surgery between April 12,005 and February 282,017 that had preoperative estimated glomerular filtration rates (eGFRs) < 15 mL/min/1.73m2 or received chronic dialysis. The index surgical procedure for each participant was categorized within one of fourteen surgical groupings based on Canadian Classification of Health Interventions (CCI) codes applied to hospitalization administrative datasets. We estimated the proportion of people that had AMI or died within 30 days of the index surgical procedure (with 95% confidence intervals [CIs]) following logistic regression, stratified by surgery type. RESULTS: Overall, 3398 people had a major surgery (1905 hemodialysis; 590 peritoneal dialysis; 903 non-dialysis). Participants were more likely male (61.0%) with a median age of 61.5 years (IQR 50.0-72.7). Within 30 days of surgery, 272 people (8.0%) had an AMI or died. The probability was lowest following ophthalmologic surgery at 1.9% (95%CI: 0.5, 7.3) and kidney transplantation at 2.1% (95%CI: 1.3, 3.2). Several types of surgery were associated with greater than one in ten risk of AMI or death, including retroperitoneal (10.0% [95%CI: 2.5, 32.4]), intra-abdominal (11.7% [8.7, 15.5]), skin and soft tissue (12.1% [7.4, 19.1]), musculoskeletal (MSK) (12.3% [9.9, 15.5]), vascular (12.6% [10.2, 15.4]), anorectal (14.7% [6.3, 30.8]), and neurosurgical procedures (38.1% [20.3, 59.8]). Urgent or emergent procedures had the highest risk, with 12.1% experiencing AMI or death (95%CI: 10.7, 13.6) compared with 2.6% (1.9, 3.5) following elective surgery. CONCLUSIONS: After major non-cardiac surgery, the risk of death or AMI for people with kidney failure varies significantly based on surgery type. This study informs our understanding of surgery type and risk for people with kidney failure. Future research should focus on identifying high risk patients and strategies to reduce these risks.

Skin cancer knowledge and photoprotective practices of organ transplant recipients.

BACKGROUND: Long-term use of immunosuppressive medications by organ transplant recipients (OTRs) leads to an increased risk of non-melanoma skin cancers (NMSCs). The objective of this study was to assess photoprotective knowledge and practices among OTRs and to identify predictors of poor sunscreen adherence and barriers to photoprotection. METHODS: A written survey was administered to 300 solid OTRs attending the Southern Alberta Transplant Program. Demographics, transplant and NMSC history, ultraviolet radiation (UVR) exposure, photoprotective knowledge and practices, and barriers to implementing photoprotection were collected. Relevant statistical analyses and univariate and multivariable regression models on sunscreen use were performed. RESULTS: One hundred and seventy-nine of the 300 respondents reported not using sunscreen most days despite 79.3% recalling have received photoprotection education. Of the surveyed OTRs, 45.7% reported no barriers to implementing photoprotective practices. On average, respondents scored 74.5% on a commonly used tool to assess photoprotective knowledge (SD 30.6%). In multivariable analyses, older age, male gender, and lack of post-secondary education were associated with lower rates of self-reported sunscreen use. The most commonly patient-reported barriers to photoprotection were "hassle/time consuming" (16.7%) and "sunscreen is uncomfortable or unpleasant" (10.0%). CONCLUSIONS: Despite OTRs self-reporting having received sufficient sun-protective knowledge and demonstrating reasonable recollection of photoprotective education on assessment, implementation of sun protection in the studied OTRs remains suboptimal.
