Telemedicine in Vascular Surgery During COVID-19 Pandemic: A Systematic Review and Narrative Synthesis.

BACKGROUND: The COVID-19 pandemic resulted in seismic changes to healthcare service delivery. The use of telemedicine was widely adopted during the pandemic, although its value in the safe care of vascular patients is unknown. METHODS: A systematic review was undertaken to identify studies that described outcomes or patient/clinician views of telemedicine (telephone or video) services in vascular surgery during or after the pandemic. Two reviewers independently searched medical databases, selected studies, extracted data, and undertook a narrative synthesis. RESULTS: Twelve studies were included. Most studies reported increased telemedicine use during the pandemic. Most patients (80.6%-100%) were satisfied with telephone or video consultation. More than 90% of the patients felt that telemedicine was a good substitute during the pandemic to avoid travelling and reduce transmission risk. Three studies showed patients had a strong preference for continuing telemedicine consultations postpandemic. Two studies evaluating patients with arterial ulceration and venous diseases reported no significant difference in clinical outcome between patients reviewed face-to-face and those seen remotely. One study showed clinicians preferred face-to-face consultations. No study conducted cost analysis. CONCLUSIONS: Patients and clinicians viewed telemedicine favorably as an alternative to face-to-face clinics during the pandemic and included studies did not identify any safety concerns. Its role postpandemic is not clearly defined, although these data suggest a significant proportion of patients would appreciate, and be suitable for, such consultations in the future.

Utilizing an office based laboratory (OBL) during the COVID-19 pandemic for vascular surgical patients.

COVID-19 pandemic brought new challenges in healthcare including the need to create tiered class recommendations about which types patients to treat urgently and which surgical cases to defer. This is a report of a single center's Office Based Laboratory (OBL) system to prioritize vascular patients and preserve acute care resources and personnel. In reviewing three months of data, it appears that by continuing to provide the urgent care needed for this chronically ill population, the insurmountable backup of surgical procedures is prevented in the operating room once elective surgeries resumed. The OBL was able to continue providing care at the same pre-pandemic rate to a large intercity population.

Racial diversity and Black vascular surgeons in vascular surgery workforce.

OBJECTIVES: The precise number of actively practicing vascular surgeons who self-identify as Black American and the historical race composition trends within the overall profession of vascular surgery are unknown. Limited demographic data have been collected and maintained at the societal or national board level. Vascular surgery societal reports suggest that less than 2% of vascular surgeons identify as Black American. Black Americans comprise 13.4% of the U.S. population yet for disorders such as peripheral artery disease and end-stage renal disease, Black communities are disproportionately impacted, and the prevalence of disease is greater on an age-adjusted basis. A significant body of research shows that clinical outcomes such as medication adherence, shared decision-making, and research trial participation are positively impacted by racial concordance especially for communities in whom distrust is high as a consequence of historic experiences. This survey aims to characterize practice and career variables within a network of Black American vascular surgeons. METHODS: A cross-sectional survey was conducted via a questionnaire sent to all participants of the Society of Black Vascular Surgeons that began to convene monthly during the COVID-19 pandemic and experienced subsequent organic growth. The survey included 20 questions with variables quantified including the surgeon's demographics, clinical experience, practice setting, patient demographics, and professional society engagement. RESULTS: Fifty-nine percent of the Society of Black Vascular Surgeons members completed the survey. Males comprised 81% of the responding vascular surgeons. The majority (62%) of respondents were involved in academic practice. Less than 25% of the total medical staff were Black American in 77% of the respondents' current work practice. The patient racial composition within their respective practice settings was as follows: White (47%), Black (34%), Hispanic (13%), Asian (3%), Middle Eastern or North African (2%), and American Indian and Alaskan Natives (0.4%). Forty-three percent of respondents had a current active membership in the Society for Vascular Surgery, and 24% had a regional society membership. Fifty-eight percent of respondents reported that they experienced a workplace event that they felt was racially or ethically driven in the 12 months before the survey. CONCLUSIONS: This survey describes an under-represented in medicine vascular surgeon subgroup that has not heretofore been characterized. Racial and ethnic demographic data are essential to better understand the current demographic makeup of our specialty and to develop benchmark goals of race composition that mirrors our society at large. The patients of this group of Black American vascular surgeons were more likely to represent a racial minority. Efforts to increase race diversity in vascular surgery have the potential benefit of enhancing care of patients with vascular disease.

High Altitude Carotid Body Tumors Growth During active Surveillance.

BACKGROUND: The gold standard for patients with carotid body tumors (CBT) is surgical resection; nevertheless, some patients are unfit for surgery or, for other reasons, could not be operated on. Active surveillance has been known to be a reasonable strategy for these cases. This study aimed to evaluate tumor growth in unoperated patients with CBTs. METHODS: A retrospective review of all unoperated patients with CBT from a single academic hospital diagnosed between 2014 and 2021 was performed. Results of nonparametric testing were presented using the median and ranges for Mann-Whitney-U or Kruskal-Wallis. Significance was defined as a 2-tailed P < .05. RESULTS: The cohort included a total of 31 patients, with a median age of 60 years (range: 37-80 years), of which 27 (87.1%) were females. The patients live at a median altitude of 2800 meters (range: 2756-2980 meters) above sea level. Twenty (64.5%) patients had Shamblin I tumors, eight (25.8%) patients had Shamblin II tumors, and three (9.7%) patients had Shamblin III tumors. Median CBT volume at diagnosis was 14.1 cm3 (range: .9 - 213.3 cm3). Median volume at diagnosis of symptomatic tumors was substantially larger than asymptomatic tumors, 49.2 cm3 vs 7.9 cm3, respectively (P = .03). Median growth of the tumors during a median 15-month follow-up (range: 3-43 months) was 3.3 cm3 (range: 0-199.9 cm3). Overall, 77% (n = 24) of the CBTs grew at least 1 cm3. CONCLUSION: Most patients in the present study had tumor growth by at least 1 cm3, with a median tumor growth of 3.3 cm.3 In the present study tumor growth was shown to be greater than other low altitude CBT active surveillance studies; therefore, surgical resection should be recommended in patients with CBT living at high altitudes.

A primer on cohort studies in vascular surgery research.

Vascular research questions can be answered using various study designs. Observational studies are used frequently to address a wide range of clinical questions when randomized clinical trials are not feasible or practical. One of the powerful vascular research tools is the cohort study. The cohort study is a reliable observational study design in which individuals who share a common characteristic (a cohort) are followed over time and their outcomes are assessed at various intervals. This review focuses on the essential characteristics, design, implementation, bias, validity, and clinical significance of cohort studies and provides illustrative examples. A cohort study can be either a prospective or a retrospective study, depending on whether the outcome occurred before or after the enrollment of the cohort. Each type has its advantages and disadvantages. Confounding, selection, and information biases can all occur in cohort studies. Applications of the cohort study design include studying the natural history of a disease, describing a condition's frequency, and investigating multiple outcomes simultaneously.

Measurement of airborne particle emission during surgical and percutaneous dilatational tracheostomy COVID-19 adapted procedures in a swine model: Experimental report and review of literature.

INTRODUCTION: Surgical tracheostomy (ST) and Percutaneous dilatational tracheostomy (PDT) are classified as high-risk aerosol-generating procedures and might lead to healthcare workers (HCW) infection. Albeit the COVID-19 strain slightly released since the vaccination era, preventing HCW from infection remains a major economical and medical concern. To date, there is no study monitoring particle emissions during ST and PDT in a clinical setting. The aim of this study was to monitor particle emissions during ST and PDT in a swine model. METHODS: A randomized animal study on swine model with induced acute respiratory distress syndrome (ARDS) was conducted. A dedicated room with controlled airflow was used to standardize the measurements obtained using an airborne optical particle counter. 6 ST and 6 PDT were performed in 12 pigs. Airborne particles (diameter of 0.5 to 3 µm) were continuously measured; video and audio data were recorded. The emission of particles was considered as significant if the number of particles increased beyond the normal variations of baseline particle contamination determinations in the room. These significant emissions were interpreted in the light of video and audio recordings. Duration of procedures, number of expiratory pauses, technical errors and adverse events were also analyzed. RESULTS: 10 procedures (5 ST and 5 PDT) were fully analyzable. There was no systematic aerosolization during procedures. However, in 1/5 ST and 4/5 PDT, minor leaks and some adverse events (cuff perforation in 1 ST and 1 PDT) occurred. Human factors were responsible for 1 aerosolization during 1 PDT procedure. ST duration was significantly shorter than PDT (8.6 ± 1.3 vs 15.6 ± 1.9 minutes) and required less expiratory pauses (1 vs 6.8 ± 1.2). CONCLUSIONS: COVID-19 adaptations allow preventing for major aerosol leaks for both ST and PDT, contributing to preserving healthcare workers during COVID-19 outbreak, but failed to achieve a perfectly airtight procedure. However, with COVID-19 adaptations, PDT required more expiratory pauses and more time than ST. Human factors and adverse events may lead to aerosolization and might be more frequent in PDT.

Drastic increase in hospital labor costs led to a sustained financial loss for an academic vascular surgery division during the coronavirus disease 2019 pandemic.

OBJECTIVE: The financial effects of the coronavirus disease 2019 (COVID-19) pandemic have fundamentally changed the healthcare environment, with hospitals expected to have lost billions in 2021. A preexisting nationwide nursing shortage became drastically worse during the pandemic amid dramatically increasing labor costs. We examined the evolution and financial effects of these changes during repeated pandemic surges within a vascular surgery division at a tertiary medical center. METHODS: Operating room, inpatient unit, and outpatient clinic financial data were examined retrospectively. The monthly averages for a 14-month control cohort before COVID-19 (January 2019 to February 2020) were compared to the averages for seven interval groups of sequential, 3-month cohorts from March 2020 through November 2021 (groups 1-7). RESULTS: The monthly relative value unit (RVU) generation had returned to the mean before the COVID-19 pandemic (2520 RVUs) after an isolated decrease early in the pandemic (group 1; 1734 RVUs). The RVUs ranged from 2540 to 2863 per month for groups 2 to 5, with a slight decline in groups 6 and 7. The average monthly RVUs in the COVID-19 period (2437 RVUs) were nearly equivalent (P = .93) to those for the pre-COVID-19 cohort. An analysis of payor mix demonstrated an increase in commercial and Medicaid payors, with a respective decrease in Medicare payors, during COVID-19. The contribution to indirect, or profit, from inpatient hospital and outpatient clinical revenue showed a drastic decrease in group 1, followed by a swift rebound when the government restrictions were eased (group 2). The total monthly vascular nursing unit expense demonstrated a marked increase with each sequential group during COVID-19, with an average monthly upsurge of +$82,171 (+47%; P < .001). An increase in the nursing labor expenses of +$884 per vascular case (from $1630 to $2514; +54%; P < .001) was observed in the COVID-19 era. The nursing labor costs per patient day had increased from $580 to $852 (+$272; +53%; P < .001). The nursing labor cost per RVU had increased from $69.5 to $107.7 (+$38.2; +55%; P < .001). On a system-wide level, the agency-related nursing costs had increased from $4.9 million to $13.6 million per month (+178%; P < .001) in 2021 compared with 2020. CONCLUSIONS: The COVID-19 pandemic has had severe, nationwide effects on healthcare delivery, exacerbating the deleterious effects of an existing, critical nursing shortage. To the best of our knowledge, the present study is the first detailed analysis of this phenomenon and its effects on a surgical division. Our results have demonstrated a progressive, drastic increase in nursing labor costs during the pandemic, with a resultant sustained erosion of financial margins despite a level of clinical productivity, as measured in RVUs, equal to the prepandemic standards. This precarious trend is not sustainable and will require increased, targeted government funding.

Society for Vascular Surgery appropriate use criteria for management of intermittent claudication.

The Society for Vascular Surgery appropriate use criteria (AUC) for the management of intermittent claudication were created using the RAND appropriateness method, a validated and standardized method that combines the best available evidence from medical literature with expert opinion, using a modified Delphi process. These criteria serve as a framework on which individualized patient and clinician shared decision-making can grow. These criteria are not absolute. AUC should not be interpreted as a requirement to administer treatments rated as appropriate (benefit outweighs risk). Nor should AUC be interpreted as a prohibition of treatments rated as inappropriate (risk outweighs benefit). Clinical situations will occur in which moderating factors, not included in these AUC, will shift the appropriateness level of a treatment for an individual patient. Proper implementation of AUC requires a description of those moderating patient factors. For scenarios with an indeterminate rating, clinician judgement combined with the best available evidence should determine the treatment strategy. These scenarios require mechanisms to track the treatment decisions and outcomes. AUC should be revisited periodically to ensure that they remain relevant. The panelists rated 2280 unique scenarios for the treatment of intermittent claudication (IC) in the aortoiliac, common femoral, and femoropopliteal segments in the round 2 rating. Of these, only nine (0.4%) showed a disagreement using the interpercentile range adjusted for symmetry formula, indicating an exceptionally high degree of consensus among the panelists. Post hoc, the term "inappropriate" was replaced with the phrase "risk outweighs benefit." The term "appropriate" was also replaced with "benefit outweighs risk." The key principles for the management of IC reflected within these AUC are as follows. First, exercise therapy is the preferred initial management strategy for all patients with IC. Second, for patients who have not completed exercise therapy, invasive therapy might provide net a benefit for selected patients with IC who are nonsmokers, are taking optimal medical therapy, are considered to have a low physiologic and technical risk, and who are experiencing severe lifestyle limitations and/or a short walking distance. Third, considering the long-term durability of the currently available technology, invasive interventions for femoropopliteal disease should be reserved for patients with severe lifestyle limitations and a short walking distance. Fourth, in the common femoral segment, open common femoral endarterectomy will provide greater net benefit than endovascular intervention for the treatment of IC. Finally, in the infrapopliteal segment, invasive intervention for the treatment of IC is of unclear benefit and could be harmful.

A Systematic Review of Simulation-Based Training in Vascular Surgery.

INTRODUCTION: Recent advancements in surgical technology, reduced working hours, and training opportunities exacerbated by the COVID-19 pandemic have led to an increase in simulation-based training. Furthermore, a rise in endovascular procedures has led to a requirement for high-fidelity simulators that offer comprehensive feedback. This review aims to identify vascular surgery simulation models and assess their validity and levels of effectiveness (LoE) for each model in order to successfully implement them into current training curricula. METHODS: PubMed and EMBASE were searched on January 1, 2021, for full-text English studies on vascular surgery simulators. Eligible articles were given validity ratings based on Messick's modern concept of validity alongside an LoE score according to McGaghie's translational outcomes. RESULTS: Overall 76 eligible articles validated 34 vascular surgery simulators and training courses for open and endovascular procedures. High validity ratings were achieved across studies for: content (35), response processes (12), the internal structure (5), relations to other variables (57), and consequences (2). Only seven studies achieved an LoE greater than 3/5. Overall, ANGIO Mentor was the most highly validated and effective simulator and was the only simulator to achieve an LoE of 5/5. CONCLUSIONS: Simulation-based training in vascular surgery is a continuously developing field with exciting future prospects, demonstrated by the vast number of models and training courses. To effectively integrate simulation models into current vascular surgery curricula and assessments, there is a need for studies to look at trainee skill retention over a longer period of time. A more detailed discussion on cost-effectiveness is also needed.

[Clinical observation on filiform-fire needling of "Biaoben acupoint combination" for 33 cases of sequelae of coronavirus disease 2019 during recovery period].

OBJECTIVE: To observe the clinical therapeutic effect of filiform-fire needling of "Biaoben acupoint combination" on the sequelae of patients with coronavirus disease 2019 (COVID-19) during the recovery period. METHODS: A total of 33 patients with COVID-19 during the recovery period were treated with filiform-fire needling at the acupoints of Mingmen (GV 4), Shenzhu (GV 12), Gaohuang (BL 43), Zusanli (ST 36) and Shangjuxu (ST 37), etc., once every other day, 3 times a week, and 3 times was one course of treatment and totally 2 courses of treatment were required. The TCM symptom, Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD) scores, pulmonary function indexes (forced vital capacity [FVC], forced expiratory volume in one second [FEV1], peak expiratory flow [PEF]) and chest CT imaging change were observed before and after treatment, and the therapeutic effect was evaluated. RESULTS: After treatment, the scores of TCM symptom, HAMA and HAMD were decreased compared with those before treatment (P<0.05), and the levels of FVC, FEV1 and PEF were increased compared with those before treatment (P<0.05), and the recovery rate of 22 patients with pulmonary ventilation dysfunction was 86.4% (19/22). After treatment, the lung shadow area was smaller than that before treatment (P<0.05). The effective rate of 25 patients with lung CT abnormalities was 84.0% (21/25). After treatment, 23 cases were cured, 5 cases were markedly effective, 4 cases were effective, 1 case was ineffective, the cured and markedly effective rate was 84.8%. CONCLUSION: The filiform-fire needling of "Biaoben acupoint combination" could significantly reduce the sequelae of cough, fatigue, chest tightness, etc. and mental symptoms such as anxiety and depression in patients with COVID-19 during the recovery period, and promote inflammatory exudation absorption of pulmonary lesion and improve lung ventilation function.

Implementation of the Vascular Surgery Board virtual certifying examination.

OBJECTIVE: The onset of the COVID-19 (coronavirus disease 2019) pandemic mandated postponement of the in-person Vascular Surgery Board 2020 certifying examination (CE). Vascular surgery virtual CEs (VVCEs) were developed for the scheduled 2020 CEs (rescheduled to January 2021) and 2021 CEs (rescheduled to July 2021) to avoid postponing the certification testing. In the present study, we have reported the development, implementation, and outcomes of the first two VVCEs. METHODS: The VVCE was similar to the in-person format (three 30-minutes sessions, two examiners, four questions) but required a proctor and a host. In contrast to the general surgery VCEs, the VVCE also incorporated images. The candidates and examiners were instructed on the format, and technology checks were performed before the VVCE. The candidates were given the opportunity to invalidate their examination for technology-related reasons immediately after the examination. Postexamination surveys were administered to all the participants. RESULTS: The VVCEs were completed by 356 of 357 candidates (99.7%). The pass rates for the January 2021 and July 2021 examinations were 97.6% (first time, 99.4%; retake, 70%) and 94.7% (first time, 94.6%; retake, 100%), respectively. The pass rates were not significantly different from the 2019 in-person CE (χ2 = 2.30; P = .13; and χ2 = 0.01; P = .91, for the January 2021 and July 2021 examinations, respectively). None of the candidates had invalidated their examination. The candidates (162 of 356; 46%), examiners (64 of 118; 54%), proctors (25 of 27; 93%), and hosts (8 of 9; 89%) completing the survey were very satisfied with the examination (Likert score 4 or 5: candidates, 92.6%; noncandidates, 96.9%) and found the technology domains (Zoom, audio, video, viewing images) to be very good (Likert score 4 or 5), with candidate and other responder scores of 73% to 84% and >94%, respectively. Significantly more of the candidates had favored a future VVCE compared with the examiners (87% vs 32%; χ2 = 67.1; P < .001). The free text responses from all responders had commented favorably on the organization and implementation of the examination. However, some candidates had expressed concerns about image sizes, and some examiners had expressed concern about the time constraints for the question format. The candidates appreciated the convenience of an at-home examination, especially the avoidance of travel costs. CONCLUSIONS: The two Vascular Surgery Board VCEs were shown to be psychometrically sound and were overwhelmingly successful, demonstrating that image-based virtual examinations are feasible and could become the standard for the future.

Telemedicine and Vascular Surgery: Expanding Access and Providing Care Through the COVID-19 Pandemic.

INTRODUCTION: Access to surgical service is limited by provider availability and geographic barriers. Telemedicine ensures that patients can access medical care. OBJECTIVE: The objective is to describe our use of telemedicine in delivering vascular surgery services to remote locations before and during the COVID-19 pandemic. METHODS: We conducted a retrospective chart review analyzing care delivered at six vascular surgery telemedicine clinics over a 22-month period. We examined vascular diagnoses, recommended interventions, referrals placed, and emergency department visits within 30 days of evaluation. We calculated travel distance saved for patients between their local clinic and our main hospital. RESULTS: We identified 94 patients and 144 telemedicine visits, with an average of 1.5 visits per patient (SD = 0.73). The most common referrals were for peripheral artery disease (20.2%) and abdominal aortic aneurysm (14.9%). Three patients were immediately referred to the emergency department due to concern for acute limb ischemia (2) or questionable symptomatic AAA (1). Telemedicine visit recommendations were distributed between no intervention (n = 30, 31.9%), medical management (n = 41, 43.6%), and surgical intervention (n = 23, 24.5%).The surgical intervention cohort was most commonly referred to arterial revascularization (n = 4), venous ablation (n = 4), and arteriovenous fistula procedures (n = 4). Fourteen patients came to our main hospital for surgery and four to local providers. Average travel distance saved per telemedicine visit was 104 miles (SD = 43.7). CONCLUSIONS: Telemedicine provided safe, efficient care during the COVID-19 pandemic and saved patients an average of 104 travel miles per visit.

Frail patients having vascular surgery during the early COVID-19 pandemic experienced high rates of adverse perioperative events and amputation.

BACKGROUND: Frailty predicts adverse perioperative outcomes and increased mortality in patients having vascular surgery. Frailty assessment is a potential tool to inform resource allocation, and shared decision-making about vascular surgery in the resource constrained COVID-19 pandemic environment. This cohort study describes the prevalence of frailty in patients having vascular surgery and the association between frailty, mortality and perioperative outcomes. METHODS: The COVID-19 Vascular Service in Australia (COVER-AU) prospective cohort study evaluates 30-day and six-month outcomes for consecutive patients having vascular surgery in 11 Australian vascular units, March-July 2020. The primary outcome was mortality, with secondary outcomes procedure-related outcomes and hospital utilization. Frailty was assessed using the nine-point visual Clinical Frailty Score, scores of 5 or more considered frail. RESULTS: Of the 917 patients enrolled, 203 were frail (22.1%). The 30 day and 6 month mortality was 2.0% (n = 20) and 5.9% (n = 35) respectively with no significant difference between frail and non-frail patients (OR 1.68, 95%CI 0.79-3.54). However, frail patients stayed longer in hospital, had more perioperative complications, and were more likely to be readmitted or have a reoperation when compared to non-frail patients. At 6 months, frail patients had twice the odds of major amputation compared to non-frail patients, after adjustment (OR 2.01; 95% CI 1.17-3.78), driven by a high rate of amputation during the period of reduced surgical activity. CONCLUSION: Our findings highlight that older, frail patients, experience potentially preventable adverse outcomes and there is a need for targeted interventions to optimize care, especially in times of healthcare stress.

Robotics in neurointerventional surgery: a systematic review of the literature.

BACKGROUND: Robotically performed neurointerventional surgery has the potential to reduce occupational hazards to staff, perform intervention with greater precision, and could be a viable solution for teleoperated neurointerventional procedures. OBJECTIVE: To determine the indication, robotic systems used, efficacy, safety, and the degree of manual assistance required for robotically performed neurointervention. METHODS: We conducted a systematic review of the literature up to, and including, articles published on April 12, 2021. Medline, PubMed, Embase, and Cochrane register databases were searched using medical subject heading terms to identify reports of robotically performed neurointervention, including diagnostic cerebral angiography and carotid artery intervention. RESULTS: A total of 8 articles treating 81 patients were included. Only one case report used a robotic system for intracranial intervention, the remaining indications being cerebral angiography and carotid artery intervention. Only one study performed a comparison of robotic and manual procedures. Across all studies, the technical success rate was 96% and the clinical success rate was 100%. All cases required a degree of manual assistance. No studies had clearly defined patient selection criteria, reference standards, or index tests, preventing meaningful statistical analysis. CONCLUSIONS: Given the clinical success, it is plausible that robotically performed neurointerventional procedures will eventually benefit patients and reduce occupational hazards for staff; however, there is no high-level efficacy and safety evidence to support this assertion. Limitations of current robotic systems and the challenges that must be overcome to realize the potential for remote teleoperated neurointervention require further investigation.

Learning in the COVID-19 pandemic and beyond: development and rapid uptake of an online learning platform for vascular surgery.

INTRODUCTION: With the onset of the COVID-19 pandemic, alternative methods of delivering medical education were rapidly required. An online learning platform was developed with the aim of providing high-quality, accessible learning to vascular specialty trainees. We describe the design, delivery and analysis of the first 15 months of the platform. Although originally a regional initiative, we discuss how popularity and feedback led to a rapid expansion of the training programme internationally. METHODS: A fully online educational platform for vascular surgery specialist trainees was developed. The primary aims and ethos of the programme were that it should be easily accessible from any location, convenient, flexible, cooperative and collaborative, social and free financially to access. All learning resources were researched carefully and based on the UK vascular surgery curriculum and 20 seminal papers targeted in the Vascular Specialist Fellow of the Royal College of Surgeons (FRCSVasc) examination. RESULTS: The project demonstrated that it is feasible to design, build and deliver a postgraduate clinical teaching platform with minimal time requirement, resources and cost while creating and maintaining high-quality content. Rapid national and international uptake has proven there is demand - in addition to overwhelmingly positive feedback from educators and learners, this demonstrates that previously perceived barriers to online education can be overcome. At present, 53 educational sessions have been delivered and are available in the online library, and in the past year (8 December 2020 to 8 December 2021) the website has been accessed 3,877 times. CONCLUSIONS: Although the programme has grown and evolved, a strong focus is being kept on its original ethos and aims - easily accessible, collaborative, free learning resources for all vascular professionals, based on the UK vascular surgery curriculum. Making learning convenient is key. The COVID-19 pandemic may be a watershed moment for a new era of learning. It is an opportunity for people from different backgrounds to share experiences and to develop cohesion within a hospital and network, nationally and worldwide.
