The use of social media and virtual opportunities by integrated vascular surgery residency programs during the COVID-19 pandemic.

OBJECTIVES: The COVID-19 pandemic has significantly affected the 2021 match application cycle as in person sub-internships and interviews have been halted. Given the abrupt change, we aimed to characterize the utilization of social media and virtual open house platforms by integrated vascular surgery residency programs for outreach and networking during the pandemic for the 2021 cycle. METHODS: A list of accredited integrated vascular surgery residency programs was compiled using the Electronic Residency Application Service (ERAS) website provided by the Academic Medical Colleges (AMC). The social media platforms Twitter, Instagram, and Facebook were queried for accounts associated with the training programs or their associated institutional vascular surgery divisions. Each discovered account was surveyed for date of creation as well as posts outlining virtual interactive events such as open houses, meet-and-greets, and virtual sub-internship opportunities. Slopes of the curves representing total account numbers and account numbers on each platform were compared from pre-COVID to current day using linear regression and t-statistics. RESULTS: There were 64 integrated vascular surgery residency programs participating in the 2021 match cycle. 70.3% (N = 45) of programs had a social media presence on at least one of the three platforms. 54.7% (N = 35) of programs had an associated Twitter account. 43.9% (N = 28) of programs had an associated Instagram account. Six (9.4%) programs were found on Facebook. The number of social media accounts significantly increased from March 2020 (37 vs 69, p < .001) to March 2021. CONCLUSIONS: Vascular surgery residency programs have significantly increased use of social media platforms over a 12-month period beginning in March 2020, indicating adaptation to the restrictions prompted by the pandemic.

Vascular complications based on mode of extracorporeal membrane oxygenation.

BACKGROUND: Vascular complications remain a prevalent and devastating complication of extracorporeal membrane oxygenation (ECMO). Risks for vascular complications have risen as the volume and medical complexity of ECMO cases has rapidly increased in recent years. This study assesses occurrence and clinical impact of vascular complications across all ECMO modes and cannulation methods in a high-volume academic center. METHODS: A retrospective single-institution review was performed of all ECMO cannulations for central or peripheral venovenous (VV) or venoarterial (VA) ECMO in 2019-2020. Patients who expired during cannulation were excluded. Primary outcomes of vascular consultation rates at or after ECMO placement, limb loss, and mortality were assessed during index hospitalization. RESULTS: A total of 229 patients were identified during the 2-year study period. VA ECMO was used in the majority of patients (n = 137, 60%), with 83% (N = 114) undergoing peripheral cannulation. Vascular surgery was consulted in 54 (23.6%) patients. Complication rates ranged from 33.9% in peripheral VA cannulation to 7% in jugular VV cannulation. Overall, 65% of vascular consults required operative intervention; interventions were highest in peripheral VA ECMO (n = 30 of 114, 26.3%). Across all ECMO types, acute limb ischemia (ALI) was the most common complication (n = 38, 16.5%), with rates ranging from 26.1% in central VA ECMO to 4.8% in jugular VV ECMO. Distal antegrade perfusion catheters (DPCs) were employed in n = 68 of 114 (59.6%) of all peripheral VA ECMO cases. Prophylactic DPCs were found to be incorrectly placed in 10.2% (n = 7 of 68) of cases, which obscured the ability to fully evaluate the effect of prophylactic DPCs on reducing rates of ALI. Major amputation (Below Knee Amputation/Above Knee Amputation) occurred in six peripheral VA patients (5.3%), two central VA patients (8.65), and two femoral-femoral VV patients (4%). Patients with ALI experienced significantly lower rates of in-hospital survival in Kaplan-Meier analysis (32.5% vs 54%, log-rank = 0.023). CONCLUSIONS: This study highlights the prevalence of vascular complications, and their associated mortality impact, across all modes of ECMO and additionally identifies several areas for institutional performance improvement. ALI was the most common complication across all cohorts and was associated with decreased in-hospital survival. The impact of DPC on ALI was difficult to elucidate due to nonstandardized placement patterns and selective use. In the care of these medically complex patients on multidisciplinary teams, review of outcomes and group discussions targeting areas for improvement are critical to success; in this study, findings resulted in the development of a lower extremity perfusion management protocol.
