Virtual medical student education and recruitment during the COVID-19 pandemic.

Due to the immediate need for social distancing, as well as widespread disruption in clinical practices, brought on by the novel severe acute respiratory syndrome coronavirus 2 (COVID-19) pandemic, medical student education rapidly shifted to a virtual format, which resulted in a variety of innovative and remotely accessible practices to address new restrictions on face-to-face education. Educators approached curriculum design seeking to replicate as much of the in-person experience as possible, and were faced with overcoming the challenges of replacing the innately hands-on nature of surgery with virtual operative and skills experiences. Restrictions on in-person visiting electives expedited the role of virtual education as a notable opportunity for medical student education and recruitment, with a variety of approaches to engaging undergraduate medical learners, including the use of live-streaming operative cases, virtual didactic curricula, and a rise in podcasts; web-based conferences; and virtual journal clubs. In addition to education, virtual outreach to medical students has become an essential tool in trainee recruitment and selection, and ongoing application of novel educational platforms will allow for new opportunities in multi-institutional collaboration and exchange with a multitude of benefits to future vascular surgery trainees. Our aim was to outline the resources and practices used to virtually teach and recruit medical students and the benefits of virtual rotations to the program and students.

Hemodynamic events during carotid stenting are associated with significant periprocedural stroke and adverse events.

BACKGROUND: There are limited data on the impact of carotid angioplasty and stenting (CAS)-related changes in blood pressure, heart rate, and preprocedural medications on periprocedural stroke in contemporary, real-world practice. This study evaluates the risk attributable to the CAS-related hemodynamic events and the impact preprocedural medications have on mitigating this risk in a large, population-based cohort. METHODS: We studied all patients in the Vascular Quality Initiative who underwent CAS between January 2006 and December 2016. Kaplan-Meier, multivariable logistic, and Cox regression analyses were used to evaluate the impact of periprocedural hypertension, hypotension, bradycardia, and medication use on immediate periprocedural stroke (IPPS), 30-day, and 1-year stroke. RESULTS: Of the 13,698 CAS procedures studied, 1239 (9.1%), 1824 (13.3%), and 1333 (9.7%) patients experienced periprocedural hypertension, hypotension, and bradycardia, respectively. IPPS was 3.2% vs 2.1% vs 0.65% (P < .001), comparing patients with periprocedural hypertension vs hypotension vs normotension and 1.4 vs 1.0% (P = .19) for bradycardic vs nonbradycardic patients. Periprocedural hypertension was associated with a four-fold increase in IPPS (adjusted odd ratio [aOR], 3.97; 95% confidence interval [CI], 2.63-5.99; P < .001). periprocedural hypotension and bradycardia were associated with 5.5-fold (aOR, 5.56; 95% CI, 3.24-9.52; P < .001) and 2.3-fold (aOR, 2.31; 95% CI, 1.26-4.25; P = .007) increases in IPPS among patients with carotid symptoms. There was 76% decrease in IPPS for patients who did not experience a periprocedural hemodynamic event (aOR, 0.24; 95% CI, 0.16-0.35; P < .001). Unlike preprocedural beta-blockers and angiotensin-converting enzyme inhibitors, prophylactic antibradyarrhythmic agents conferred a 58% reduction in IPPS among patients with carotid symptoms (aOR, 0.42; 95% CI, 0.23-0.78; P = .006). The periprocedural hemodynamic events were also associated with 7.7-fold increase in myocardial infarction (aOR, 7.70; 95% CI, 4.77-12.45; P < .001), a 2.2-fold increase in 30-day mortality (aOR, 2.24; 95% CI, 1.61-3.12; P < .001), and a 16% increase in length of stay (aOR, 1.16; 95% CI, 0.04-2.28; P = .042). The occurrence of these hemodynamic events is higher in patients with prior cardiac disease and the difference in periprocedural outcomes extended to 1 year. CONCLUSIONS: Periprocedural hemodynamic events are associated with an increase in periprocedural stroke, myocardial infarction, death, and length of stay. Periprocedural hypertension in all patients; hypotension and bradycardia in patients with symptomatic carotid disease are associated with significant increase in IPPS. Prophylactic antibradyarrhythmic agents are associated with decrease in bradycardia and IPPS. These results heighten the need to anticipate and promptly address these CAS-related hemodynamic events, especially in susceptible patients.

Trauma morning report is the ideal environment to teach and evaluate resident communication and sign-outs in the 80 hour work week.

BACKGROUND: The 80h work week has raised concerns that complications may increase due to multiple sign-outs or poor communication. Trauma Surgery manages complex trauma and acute care surgical patients with rapidly changing physiology, clinical demands and a large volume of data that must be communicated to render safe, effective patient care. Trauma Morning Report format may offer the ideal situation to study and teach sign-outs and resident communication. MATERIALS AND METHODS: Surgery Residents were assessed on a 1-5 scale for their ability to communicate to their fellow residents. This consisted of 10 critical points of the presentation, treatment and workup from the previous night's trauma admissions. Scores were grouped into three areas. Each area was scored out of 15. Area 1 consisted of Initial patient presentation. Area 2 consisted of events in the trauma bay. Area 3 assessed clarity of language and ability to communicate to their fellow residents. The residents were assessed for inclusion of pertinent positive and negative findings, as well as overall clarity of communication. In phase 1, residents were unaware of the evaluation process. Phase 2 followed a series of resident education session about effective communication, sign-out techniques and delineation of evaluation criteria. Phase 3 was a resident-blinded phase which evaluated the sustainability of the improvements in resident communication. RESULTS: 50 patient presentations in phase 1, 200 in phase 2, and 50 presentations in phase 3 were evaluated. Comparisons were made between the Phase 1 and Phase 2 evaluations. Area 1 (initial events) improved from 6.18 to 12.4 out of 15 (p<0.0001). Area 2 (events in the trauma bay) improved from 9.78 to 16.53 (p<0.0077). Area 3 (communication and language) improved from 8.36 to 12.22 out of 15 (P<0.001). Phase 2 to Phase 3 evaluations were similar, showing no deterioration of skills. CONCLUSIONS: Trauma Surgery manages complex surgical patients, with rapidly changing physiologic and clinical demands. Trauma Morning Report, with diverse attendance including surgical attendings and residents in various training years, is the ideal venue for real-time teaching and evaluation of sign-outs and reinforcing good communication skills in residents.

The geriatric cytokine response to trauma: time to consider a new threshold.

BACKGROUND: Inflammatory responses to trauma, especially if exaggerated, drive mortality and morbidities including infectious complications. Geriatric patients are particularly susceptible to profound inflammation. Age-related declines in inflammatory and immune systems are known to occur. Geriatric patients display dampened inflammatory responses to non-critical disease processes. Specific inflammatory responses in critically ill geriatric trauma patients, and how the inflammatory profile associated with subsequent infections or mortality, remain unknown. METHODS: Geriatric (≥65 y) and young (18-50 y old) critically ill blunt trauma intensive care unit (ICU) patients were enrolled prospectively. Blood was drawn within 36 h of presentation to measure circulating cytokines including interleukin (IL)-6 (pg/mL), IL-10 (pg/mL), and tumor necrosis factor (TNF)-α (pg/mL) levels. Age, gender, Acute Physiology and Chronic Health Evaluation (APACHE II) score and outcomes were reviewed. RESULTS: Twenty-one young and 29 geriatric critically ill patients were recruited. Groups were comparable in male gender and age-adjusted APACHE II score, but geriatric patients had higher mortality (38% versus 9.5%; p=0.04). Within geriatric trauma patients, the development of a secondary infection was associated with significantly lower presenting IL-6 and IL-10 levels and no difference in TNF-α levels. Furthermore, geriatric patients who died had elevated IL-6 and IL-10 and decreased TNF-α levels compared with geriatric patients who lived. Compared with the young cohort, IL-6 and IL-10 levels were similar between geriatric patients who died and young patients who lived. However, geriatric patients who lived, compared with young patients who lived, had significantly lower IL-6 and IL-10. There was no such relation noted with TNF-α. CONCLUSIONS: A lowered inflammatory response in geriatric patients is associated with the development of a subsequent infection. However, geriatric patients exhibiting inflammatory responses as robust as their younger counterparts have increased mortality. Redefining our understanding of an appropriate geriatric inflammatory response to trauma will help future therapy, thereby improving morbidity and mortality.
