The Thoracic Surgery Medical Student Association: Understanding the needs of medical students pursuing cardiothoracic surgery in the United States.

OBJECTIVE: Founded in 2020, the Thoracic Surgery Medical Student Association is the first national organization dedicated to supporting medical students interested in pursuing cardiothoracic surgery. Our inaugural survey aimed to describe their basic characteristics and needs. METHODS: An Institutional Review Board-approved, nonincentivized, anonymous electronic survey was distributed to any medical students enrolled in Liaison Committee on Medical Education-accredited medical schools through social media such as Twitter, national organizations (Association of Women Surgeons, Thoracic Surgery Resident Association), and medical school cardiothoracic surgery interest groups. Their basic characteristics, attitudes, and preferences regarding cardiothoracic surgery were recorded. RESULTS: Of the 167 students from 117 unique schools who completed the survey, 53% identified as White and 57% identified as female. Stages of training were well distributed: 16% first-year medical students, 33% second-year medical students, 16% third-year medical students, 21% fourth-year medical students, and 14% dual degree/research students. Most participants (57%) did not have (32%) or were not aware of having (25%) a thoracic surgery training program at their home institution. The majority (72%) of students reported not having a cardiothoracic surgery interest group at their home institution. The most desired areas of cardiothoracic were networking (31%) and mentorship (28%). CONCLUSIONS: There is a significant need to directly engage medical students who are interested in cardiothoracic surgery considering limited exposure at home institutions through a lack of cardiothoracic surgery interest groups and cardiothoracic residency programs. The Thoracic Surgery Medical Student Association is poised to address these areas with directed networking by connecting cardiothoracic surgery faculty and residents from other institutions with medical students interested in pursuing cardiothoracic surgery.

Volume of frail patients predicts outcome in frail patients after cardiac surgery.

OBJECTIVE: Recent data from major noncardiac surgery suggest that outcomes in frail patients are better predicted by a hospital's volume of frail patients specifically, rather than overall surgical volume. We sought to evaluate this "frailty volume-frailty outcome relationship" in patients undergoing cardiac surgery. METHODS: We studied 72,818 frail patients undergoing coronary artery bypass grafting or valve replacement surgery from 2010 to 2014 using the Nationwide Readmissions Database. Frailty was defined using the Johns Hopkins Adjusted Clinical Groups frailty-defining diagnoses indicator. Multilevel logistic regression was used to assess the independent effect of frailty volume by quartile on mortality, surgical complications, failure to rescue, nonhome discharge, 30-day readmissions, length of stay, and hospital costs in frail patients. RESULTS: In comparing the highest volume quartiles with the lowest, both overall cardiac surgical volume and volume for frail patients were significantly associated with shorter length of stay and reduced costs. However, frailty volume was also independently associated with significantly reduced in-hospital mortality (odds ratio, 0.79; 95% confidence interval, 0.67-0.94; P = .006) and failure to rescue (odds ratio, 0.83; 95% confidence interval, 0.70-0.98; P = .03), whereas no such association was seen between overall volume and either mortality (odds ratio, 0.94; 95% confidence interval, 0.74-1.10; P = .43) or failure to rescue (odds ratio, 0.98; 95% confidence interval, 0.83-1.17; P = .85). Neither frailty volume nor overall volume showed any significant relationship with the rate of 30-day readmissions. CONCLUSIONS: In frail patients undergoing cardiac surgery, surgical volume of frail patients was a significant independent of predictor of in-hospital mortality and failure to rescue, whereas overall surgical volume was not. Thus, the "frailty volume-outcome relationship" superseded the traditional "volume-outcome relationship" in frail patients with cardiac disease.

How Should ECMO Be Used Under Conditions of Severe Scarcity? A Population Study of Public Perception.

OBJECTIVE: To assess societal preferences regarding allocation of extracorporeal membrane oxygenation (ECMO) as a rescue option for select patients with coronavirus disease 2019 (COVID-19). DESIGN: Cross-sectional survey of a nationally representative sample. SETTING: Amazon Mechanical Turk platform. PARTICIPANTS: In total, responses from 1,041 members of Amazon Mechanical Turk crowd-sourcing platform were included. Participants were 37.9 ± 12.6 years old, generally white (65%), and college-educated (66.1%). Many reported working in a healthcare setting (22.5%) and having a friend or family member who was admitted to the hospital (43.8%) or died from COVID-19 (29.9%). MEASUREMENTS AND MAIN RESULTS: Although most reported an unwillingness to stay on ECMO for >one week without signs of recovery, participants were highly supportive of ECMO utilization as a life-preserving technique on a policy level. The majority (96.7%) advocated for continued use of ECMO to treat COVID patients during periods of resource scarcity but would prioritize those with highest likelihood of recovery (50%) followed by those who were sickest regardless of survival chances (31.7%). Patients >40 years old were more likely to prefer distributing ECMO on a first-come first-served basis (21.5% v 13.3%, p < 0.05). CONCLUSION: Even though participants expressed hesitation regarding ECMO in personal circumstances, they were uniformly in support of using ECMO to treat COVID patients at a policy level for others who might need it, even in the setting of severe scarcity.

Neighborhood socioeconomic status is associated with differences in operative management and long-term survival after coronary artery bypass grafting.

OBJECTIVE: We sought to characterize differences in operative management and surgical outcomes after coronary artery bypass grafting associated with the socioeconomic context in which a patient lives. METHODS: We used a validated index of 17 variables derived from the US Census Bureau to assign socioeconomic status at the block group level to patients who underwent isolated coronary artery bypass grafting at a single institution over a 16-year period. Operative mortality, stroke, renal failure, prolonged ventilation, sternal wound infection, reoperation, composite morbidity or mortality, long-term survival, and use of arterial conduits were the outcomes assessed. RESULTS: This study was composed of 6751 patients. Lower socioeconomic status was significantly associated with increased rates of stroke, renal failure, prolonged ventilation, and composite morbidity or mortality in a multivariable analysis. Low socioeconomic status was significantly associated with poorer long-term adjusted survival (hazard ratio, 1.26; 95% confidence interval, 1.03-1.55). Finally, lower socioeconomic status was significantly associated with decreased use of more than 1 arterial conduits in a multivariable analysis. CONCLUSIONS: The socioeconomic context in which a patient lives is significantly associated with short- and long-term outcomes after coronary artery bypass grafting. There may also be variation in operative management, demonstrated by decreased use of arterial conduits. Lower rates of arterial revascularization among socioeconomically disadvantaged patients who undergo coronary artery revascularization may provide a target for intervention.
