RESUMEN

Background: Communication skills are foundational to the practice of medicine and training to build them is recommended. Serious illness communication skills (SICSs) teaching is inconsistently and sparsely taught in postgraduate training and residents report feeling inadequately trained to have difficult conversations. The authors developed an e-module demonstrating high-yield communication skills from a known evidence-based training program to standardize core SICS teaching and questioned how using it before skills practice impacted comfort and preparedness for residents to complete advance care planning (ACP). Methods: Family medicine residents at an academic hospital in Toronto, Canada, completed a novel e-module that replaced a typical didactic-lecture introducing core SICS relevant to ACP conversations. Residents then discussed the skills, followed by practicing them deliberately in a structured role-play simulation with feedback by trained facilitators. Residents completed pre- and post-intervention attitudinal surveys. Results: Residents preferred a combination of learning modalities and welcomed online and virtual teaching methods for learning SICS. Residents reported higher levels of preparedness for engaging in ACP, delivering serious news, and discussing goals of care post-intervention. Residents showed more interest in discussing ACP post-intervention but questioned feasibility for doing so in busy ambulatory clinics. Conclusion: Scalable time-efficient teaching strategies are needed to fill a known education gap. This study demonstrated benefits of incorporating brief e-module learning into residents' preparation for SICS training using deliberate practice simulation training. The online, interactive virtual training improved resident readiness and comfort for ACP, an area often overlooked in medical education. Moreover, it provides an evidence-informed standardized tool for clinician teachers to seamlessly incorporate into their teaching practices.

RESUMEN

OBJECTIVES: Ruptured abdominal aortic aneurysm (rAAA) is a life-threatening condition, and rapid diagnosis is necessary to facilitate early surgical intervention. We sought to evaluate the accuracy of presenting symptoms, physical examination signs, computed tomography with angiography (CTA), and point-of-care ultrasound (PoCUS) for diagnosis of rAAA. METHODS: We searched six databases from inception through April 2021. We included studies investigating the accuracy of any of the above tests for diagnosis of rAAA. The primary reference standard used in all studies was intraoperative diagnosis or death from rAAA. Because PoCUS cannot detect rupture, we secondarily assessed its accuracy for the diagnosis of AAA, using the reference standard of intraoperative or CTA diagnosis. We used GRADE to assess certainty in estimates. RESULTS: We included 20 studies (2,077 patients), with 11 of these evaluating signs and symptoms, seven evaluating CTA, and five evaluating PoCUS. Pooled sensitivities of abdominal pain, back pain, and syncope for rAAA were 61.7%, 53.6%, and 27.8%, respectively (low certainty). Pooled sensitivity of hypotension and pulsatile abdominal mass were 30.9% and 47.1%, respectively (low certainty). CTA had a sensitivity of 91.4% and specificity of 93.6% for diagnosis of rAAA (moderate certainty). In our secondary analysis, PoCUS had a sensitivity of 97.8% and specificity of 97.0% for diagnosing AAA in patients suspected of having rAAA (moderate certainty). CONCLUSIONS: Classic clinical symptoms associated with rAAA have poor sensitivity, and their absence does not rule out the condition. CTA has reasonable accuracy, but misses some cases of rAAA. PoCUS is a valuable tool that can help guide the need for urgent transfer to a vascular center in patients suspected of having rAAA.

RESUMEN

In 2017, The Ottawa Hospital initiated a unique-in-Canada quality improvement initiative by opening a novel, multi-specialist limb-preservation clinic. We sought to describe the structure, processes, and initial outcomes of the clinic and evaluate whether it is achieving its mandate of providing high-quality wound clinical care, education, and research. We conducted a descriptive prospective cohort study alongside a nested study of 162 clinic patients requiring serial assessments. There have been 1623 visits, mostly (72.2%) from outpatients. During 17.8% of visits, patients were evaluated by >1 specialist. Therapies provided most often included negative-pressure wound therapy (32.7%), biological wound dressings (21.6%), and total contact casting (18.5%). Furthermore, 1.2% underwent toe/ray amputations or skin grafting in clinic and 22.8% were initiated on antimicrobials. Mixed-effects models suggested that mean wound volumes for those requiring serial assessments decreased by 1.6 (95% confidence interval = -0.86 to -2.27) cm3 between visits. The clinic provided seven rotations to vascular surgery, infectious diseases, dermatology, and palliative care physicians; three nursing preceptorships; and two educational workshops. It also initiated provincial and national vascular health and wound care research initiatives. This study may be used to guide development of other limb-preservation clinics and programmes. Findings support that our programme is achieving its mandate.

RESUMEN

INTRODUCTION: There has been limited study of patient-reported outcomes (PROs) in patients at risk of limb loss. Our primary objective was to estimate the prevalence of disability in this patient population using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). MATERIALS AND METHODS: We recruited patients referred to a limb-preservation clinic. Patients self-reported their disability status using the 12-domain WHODAS 2.0. Severity of disability in each domain was scored from 1 = none to 5 = extreme and the total normalized to a 100-point scale (total score ≥25 = clinically significant disability). We also asked patients about wound-specific concerns and wound-related discomfort or distress. RESULTS: We included 162 patients. Reasons for clinic referral included arterial-insufficient (37.4%), postoperative (25.9%), and mixed etiology (10.8%) wounds. The mean WHODAS 2.0 disability score was 35.0 (standard deviation = 16.0). One-hundred-and-nineteen (73.5%) patients had clinically significant disability. Patients reported they had the greatest difficulty walking a long distance (mean score = 4.2), standing for long periods of time (mean score = 3.6), taking care of household responsibilities (mean score = 2.7), and dealing with the emotional impact of their health problems (mean score = 2.5). In the two-weeks prior to presentation, 87 (52.7%) patients expressed concern over their wound(s) and 90 (55.6%) suffered a moderate amount or great deal of wound-related discomfort or distress. In adjusted ordinary least squares regression models, although WHODAS 2.0 disability scores varied with changes in wound volume (p = 0.03) and total revised photographic wound assessment tool scores (p<0.001), the largest decrease in disability severity was seen in patients with less wound-specific concerns and wound-related discomfort and distress. DISCUSSION: The majority of people at risk of limb loss report suffering a substantial burden of disability, pain, and wound-specific concerns. Research is needed to further evaluate the WHODAS 2.0 in a multicenter fashion among these patients and determine whether care and interventions may improve their PROs.

RESUMEN

INTRODUCTION: Patients with peripheral arterial disease (PAD) are at increased risk for systemic arterial thromboembolic events. Females represent a unique subset of patients with PAD, who differ from males in important ways: they have smaller diameter vessels, undergo lower extremity bypass less frequently and experience higher rates of graft occlusion, amputation and mortality than males. Females also trend towards higher rates of major coronary events and cardiovascular mortality. Current guidelines recommend monoantiplatelet therapy (MAPT) for secondary prevention in patients with symptomatic PAD. However, indications for more intensive antithrombotic therapy in this cohort-especially among females who are frequently under-represented in randomised controlled trials (RCTs)-remain unclear. As newer antithrombotic therapies emerge, some RCTs have demonstrated differential effects in females versus males. A systematic review is needed to quantify the rates of arterial thromboembolic and bleeding events with different antithrombotic regimens in females with symptomatic PAD. METHODS AND ANALYSIS: We will search MEDLINE, Embase and the Cochrane Central Register of Controlled trials for published RCTs that include females with symptomatic PAD and compare full dose anticoagulation±antiplatelet therapy, dual pathway inhibition or dual antiplatelet therapy with MAPT. Title, abstract and full-text screening will be conducted in duplicate by three reviewers. Authors will be contacted to obtain sex-stratified outcomes as needed. Risk of bias will be assessed using the Cochrane Risk of Bias tool. Data will be extracted by independent reviewers and confirmed by a second reviewer. Quantitative synthesis will be conducted using Review Manager (RevMan) V.5 for applicable outcomes data. Planned subgroup analysis by PAD severity, vascular intervention and indication for antithrombotics will be conducted where data permits. ETHICS AND DISSEMINATION: Ethics approval is waived as the study does not involve primary data collection. This review will be submitted for publication in a peer-reviewed journal and for presentation at national and international scientific meetings. TRIAL REGISTRATION NUMBER: This protocol was registered with the PROSPERO International Prospective Register of Systematic Reviews (ID# CRD42020196933).

RESUMEN

Since COVID-19 was declared a pandemic a year ago, our understanding of its effects on the vascular system has slowly evolved. At the cellular level, SARS-CoV-2 - the virus that causes COVID-19 - accesses the vascular endothelium through the angiotensin-converting enzyme 2 (ACE-2) receptor and induces proinflammatory and prothrombotic responses. At the clinical level, these pathways lead to thromboembolic events that affect the pulmonary, extracranial, mesenteric, and lower extremity vessels. At the population level, the presence of vascular risk factors predisposes individuals to more severe forms of COVID-19, whereas the absence of vascular risk factors does not spare patients with COVID-19 from unprecedented rates of stroke, pulmonary embolism and acute limb ischemia. Finally, at the community and global level, the fear of COVID-19, measures taken to limit the spread of SARS-CoV-2 and reallocation of limited hospital resources have led to delayed presentations of severe forms of ischemia, surgery cancellations and missed opportunities for limb salvage. The purpose of this narrative review is to present some of the data on COVID-19, from cellular mechanisms to clinical manifestations, and discuss its impact on the local and global surgical communities from a vascular perspective.

Depuis que la COVID-19 s'est vu donner le statut de pandémie il y a 1 an, notre connaissance des effets de cette maladie sur le système vasculaire a évolué. À l'échelle cellulaire, le SRAS-CoV-2 ­ le virus qui cause la COVID-19 ­ accède à l'endothélium vasculaire par le récepteur de l'enzyme de conversion de l'angiotensine-2 (ACE-2) et provoque des réponses proinflammatoires et prothrombotiques. À l'échelle clinique, ces réponses peuvent mener à une activité thromboembolique touchant les vaisseaux pulmonaires, extracrâniens, mésentériques et des membres inférieurs. À l'échelle populationnelle, la présence chez certaines personnes de facteurs de risque vasculaires les prédispose à une forme plus grave de la COVID-19, mais l'absence de ces facteurs n'empêche pas les patients atteints de la COVID-19 de présenter des taux sans précédent d'AVC, d'embolie pulmonaire et d'ischémie aiguë aux membres. Enfin, à l'échelle locale et mondiale, la peur entourant la COVID-19, les mesures prises pour en endiguer la propagation et le redéploiement des ressources limitées des hôpitaux ont mené au report de visites à l'hôpital pour des formes graves d'ischémie, à l'annulation de chirurgies et à des occasions manquées de préserver des membres. La présente revue non systématique a pour objectif de présenter une partie des données sur la COVID-19, de ses mécanismes cellulaires à ses manifestations cliniques, et de discuter des répercussions de la crise sur les communautés chirurgicales locales et mondiales, dans une optique vasculaire.
