    Background: In light of the global climate emergency, it is worth reconsidering the current practice of medical students traveling to interview for residency positions. We sought to estimate carbon dioxide (CO2) emissions associated with travel for general surgery residency interviews in Canada, and the potential avoided emissions if interviews were restructured. Methods: An 8-item survey was constructed to collect data on cities visited, travel modalities, and costs incurred. Applicants to the University of Ottawa General Surgery Program during the 2019/20 Canadian Resident Matching Service (CaRMS) cycle were invited to complete the survey.  Potential reductions in CO2 emissions were modeled using a regionalized interview process with either one or two cities. Results: Of a total of 56 applicants, 39 (70%) completed the survey. Applicants on average visited 10 cities with a mean total cost of $4,866 (95% CI=3,995-5,737) per applicant. Mean CO2 emissions were 1.82 (95% CI=1.50-2.14) tonnes per applicant, and the total CO2 emissions by applicants was estimated to be 101.9 (95% CI=84.0 – 119.8) tonnes. In models wherein interviews are regionalized to one or two cities, emissions would be 57.9 tonnes (43.2% reduction) and 84.2 tonnes (17.4% reduction), respectively. Overall, 74.4% of respondents were concerned about the environmental impact of travel and 46% would prefer to interview by videoconference. Conclusion: Travel for general surgery residency interviews in Canada is associated with a considerable environmental impact. These findings are likely generalizable to other residency programs. Given the global climate crisis, the CaRMS application process must consider alternative structures.Contexte: Compte tenu de la situation d’urgence climatique mondiale, il convient de reconsidĂ©rer l’usage actuel selon lequel les Ă©tudiants en mĂ©decine se dĂ©placent pour se prĂ©senter aux entrevues en vue d’obtenir un poste de rĂ©sidence.

Les candidats ont visitĂ© en moyenne 10 villes, pour un coĂ»t total moyen de 4 866 dollars (IC 95 % = 3 995-5 737) par candidat. Les Ă©missions moyennes de CO2 Ă©taient de 1,82 (IC 95 % = 1,50-2,14) tonne par candidat, et le total des Ă©missions de CO2 pour l’ensemble des candidats Ă©tait estimĂ© Ă  101,9 (IC 95 % = 84,0 - 119,8) tonnes. D’aprĂšs les modĂšles oĂč les entrevues sont rĂ©gionalisĂ©es avec une ou deux villes, les Ă©missions seraient respectivement de 57,9 tonnes (43,2 % de rĂ©duction) et 84,2 tonnes (17,4 % de rĂ©duction). Dans l’ensemble, 74,4 % des personnes interrogĂ©es se disent prĂ©occupĂ©es par l’impact environnemental des dĂ©placements et 46 % prĂ©fĂ©reraient que l’entretien se fasse par vidĂ©oconfĂ©rence. Conclusion : Les dĂ©placements pour les entrevues de rĂ©sidence en chirurgie gĂ©nĂ©rale au Canada ont un impact environnemental considĂ©rable. Ces conclusions sont probablement gĂ©nĂ©ralisables Ă  d’autres programmes de rĂ©sidence. Compte tenu de la crise climatique mondiale, il conviendrait d’envisager d’autres modalitĂ©s d’organisation des entrevuespour le processus de candidatures du CaRMS

    Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Current management of cryptoglandular fistula-in-ano

    Fistula-in-ano is a difficult problem that physicians have struggled with for centuries. Appropriate treatment is based on 3 central tenets: (1) control of sepsis; (2) closure of the fistula; and (3) maintenance of continence. Treatment options continue to evolve - as a result, it is important to review old and new options on a regular basis to ensure that our patients are provided with up to date information and options. This paper will briefly cover some of the traditional approaches that have been used as well as some newer promising procedures

    Can text-search methods of pathology reports accurately identify patients with rectal cancer in large administrative databases?

    Background: The aim of this study is to derive and to validate a cohort of rectal cancer surgical patients within administrative datasets using text-search analysis of pathology reports. Materials and Methods: A text-search algorithm was developed and validated on pathology reports from 694 known rectal cancers, 1000 known colon cancers, and 1000 noncolorectal specimens. The algorithm was applied to all pathology reports available within the Ottawa Hospital Data Warehouse from 1996 to 2010. Identified pathology reports were validated as rectal cancer specimens through manual chart review. Sensitivity, specificity, and positive predictive value (PPV) of the text-search methodology were calculated. Results: In the derivation cohort of pathology reports (n = 2694), the text-search algorithm had a sensitivity and specificity of 100% and 98.6%, respectively. When this algorithm was applied to all pathology reports from 1996 to 2010 (n = 284,032), 5588 pathology reports were identified as consistent with rectal cancer. Medical record review determined that 4550 patients did not have rectal cancer, leaving a final cohort of 1038 rectal cancer patients. Sensitivity and specificity of the text-search algorithm were 100% and 98.4%, respectively. PPV of the algorithm was 18.6%. Conclusions: Text-search methodology is a feasible way to identify all rectal cancer surgery patients through administrative datasets with high sensitivity and specificity. However, in the presence of a low pretest probability, text-search methods must be combined with a validation method, such as manual chart review, to be a viable approach
