Outcomes of acute type A aortic dissection during the COVID-19 pandemic: An analysis of the Society of Thoracic Surgeons Database.

PURPOSE: There have been reported reductions of hospital presentation for acute cardiovascular conditions such as myocardial infarction and acute type A aortic dissection (ATAAD) in the United States during the COVID-19 pandemic. This study examined presentation patterns and outcomes of ATAAD in North America immediately before, and during, the COVID-19 pandemic. METHODS: The Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS ACSD) was queried to identify patients presenting with ATAAD in the 12 months pre-pandemic (March 2019-February 2020), and during the early pandemic (March through June 2020). Demographics and operative characteristics were compared using χ² test and Wilcoxon Rank-sum test. The median annual case volume designated low-volume centers versus high-volume centers (>10 cases per month). Step-wise variable selection was used to create a risk set used for adjustment of all multivariable models. RESULTS: There were 5480 patients identified: 4346 pre-pandemic and 1134 during pandemic. There was significantly lower volume of median cases per month during the COVID-19 pandemic period (286 interquartile range [IQR]: 256-306 vs. 372 IQR: 291-433,p = .0152). In historically low-volume centers (<10 cases per year), there was no difference in volume between the two periods (142 IQR: 133-166 vs. 177 IQR: 139-209, p = NS). In high-volume centers, there was a decline during the pandemic (140 IQR: 123-148 vs. 212 IQR: 148-224, p = .0052). There was no difference in overall hospital-to-hospital transfers during the two time periods (54% of cases pre-pandemic, 55% during). Patient demographics, operative characteristics, malperfusion rates, and cardiac risk factors were similar between the two time periods. There was no difference in unadjusted operative mortality (19.01% pre-pandemic vs. 18.83% during, p = .9) nor major morbidity (52.42% pre-pandemic vs. 51.24% during, p = .5). Risk-adjusted multivariable models showed no difference in either operative mortality nor major morbidity between time periods. CONCLUSIONS: For patients presenting to the hospital with ATAAD during the first surge of the pandemic, operative outcomes were similar to pre-pandemic despite a 30% reduction in volume. Out-of-hospital mortality from ATAAD during the pandemic remains unknown. Further understanding these findings will inform management of ATAAD during future pandemics.

The Effect of COVID-19 on Cardiac Surgical Volume and its Associated Costs.

The COVID-19 pandemic significantly affected health care and in particular surgical volume. However, no data surrounding lost hospital revenue due to decreased cardiac surgical volume have been reported. The National Inpatient Sample database was used with decreases in cardiac surgery at a single center to generate a national estimate of decreased cardiac operative volume. Hospital charges and provided charge to cost ratios were used to create estimates of lost hospital revenue, adjusted for 2020 dollars. The COVID period was defined as January to May of 2020. A Gompertz function was used to model cardiac volume growth to pre-COVID levels. Single center cardiac case demographics were internally compared during January to May for 2019 and 2020 to create an estimate of volume reduction due to COVID. The maximum decrease in cardiac surgical volume was 28.3%. Cumulative case volume and hospital revenue loss during the COVID months as well as the recovery period totaled over 35 thousand cases and 2.5 billion dollars. Institutionally, patients during COVID months were younger, more frequently undergoing a CABG procedure, and had a longer length of stay. The pandemic caused a significant decrease in cardiac surgical volume and a subsequent decrease in hospital revenue. This data can be used to address the accumulated surgical backlog and programmatic changes for future occurrences.

The impact of coronavirus 2019 on general surgery residency: A national survey of program directors.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has had a widespread impact on graduate medical education. This survey aims to assess how general surgery residency programs adapted to the initial wave of the COVID-19 pandemic in the United States (US). MATERIALS AND METHODS: General surgery program directors (PDs) in the US were invited to partake in a 16-question survey between April 17 and May 1, 2020. The survey included questions about basic program information, clinical practice changes, changes to education structure, surgery resident clinical duties, and perceived impact on resident operative experience and future career choices. RESULTS: Forty-eight PDs completed the survey in the designated two-week period. Almost all (44/48, 91.7%) programs changed their didactic education to an online video conference-based format. Thirteen programs (27.1%) decreased the amount/frequency of formal education, and 13 (27.1%) reported canceling didactic education for some period of time. The majority of PDs (26/48, 54.2%) felt these changes had no impact on resident didactic participation, 14 (29.2%) reported an increase in participation, and 8 (16.7%) reported decreased participation. Ten programs (20.8%) redeployed residents to non-surgical services at the time of this survey, 30 (62.5%) have not redeployed residents but plan to if needed, and 8 (16.7%) did not have any plans to redeploy residents. CONCLUSIONS: The outbreak of COVID-19 has required general surgery residency PDs to change numerous aspects of resident education and clinical roles. Future inquiry is needed to assess if these changes lead to appreciable differences in resident preparedness and career selection.

The impact of COVID-19 on thoracic surgery residency programs in the US: A program director survey.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) has altered how the current generation of thoracic surgery residents are being trained. The aim of this survey was to determine how thoracic surgery program directors (PDs) are adapting to educating residents during the COVID-19 pandemic. METHODS: Thoracic surgery PDs of integrated, traditional (2 or 3 year), and combined 4 + 3 general/thoracic surgery training programs in the United States were surveyed between 17th April and 1st May 2020 during the peak of the COVID-19 pandemic in much of the United States. The 15-question electronic survey queried program status, changes to the baseline surgical practice, changes to didactic education, deployment/scheduling of residents, and effect of the pandemic on case logs and preparedness for resident graduation. RESULTS: All 23 institutions responding had ceased elective procedures, and most had switched to telemedicine clinic visits. Online virtual didactic sessions were implemented by 91% of programs, with most (69.6%) observing same or increased attendance. PDs reported that 82.7% of residents were on a non-standard schedule, with most being deployed in a 1 to 2 week on, 1 to 2 week off block schedule. Case volumes were affected for both junior and graduating trainees, but a majority of PDs report that graduating residents will graduate on time without perceived negative effect on first career/fellowship position. CONCLUSIONS: The COVID-19 pandemic has radically changed the educational approach of thoracic surgery programs. PDs are adapting educational delivery to optimize training and safety during the pandemic. Long-term effects remain uncertain and require additional study.

The importance of repeat testing in detecting coronavirus disease 2019 (COVID-19) in a coronary artery bypass grafting patient.

While elective cardiac surgeries have been postponed to prevent coronavirus disease 2019 (COVID-19) transmission and to reduce resource utilization, patients with urgent indications necessitating surgery may still be at risk of contracting the disease throughout their postoperative recovery. We present a case of an 81-year-old female who underwent urgent coronary artery bypass grafting and was readmitted following discharge to a nursing facility with a cluster of COVID-19 cases. Despite symptomatology and imaging concerning for COVID-19, two initial reverse transcription polymerase chain reaction (RT-PCR) tests were negative but a third test was positive. This case emphasizes the risks of discharge location in the COVID-19 era as well as the importance of clinical suspicion, early isolation practices for those presumed positive, and repeat testing, given the marginal sensitivity of available COVID-19 RT-PCR.

The role of extracorporeal life support for patients with COVID-19: Preliminary results from a statewide experience.

OBJECTIVE: There is a paucity of clinical data on critically ill patients with COVID-19 requiring extracorporeal life support. METHODS: A statewide multi-institutional collaborative for COVID-19 patients was utilized to obtain clinical data on the first 10 critically ill COVID-19 patients who required extracorporeal membrane oxygenation (ECMO). RESULTS: Of the first 10 patients that required ECMO for COVID-19, the age ranged from 31 to 62 years with the majority (70%) being men. Seven (70%) had comorbidities. The majority (80%) of patients had known sick contact and exposure to COVID-19 positive patients or traveled to pandemic areas inside the United States within the 2 weeks before symptom onset. None of the patients were healthcare workers. The most common symptoms leading to the presentation were high fever ≥103°F (90%), cough (80%) and dyspnea (70%), followed by fatigue and gastrointestinal symptoms (both 30%), myalgia, loss of taste, pleuritic chest pain, and confusion (all 10%). All patients had bilateral infiltrates on chest X-rays suggestive of interstitial viral pneumonia. All patients were cannulated in the venovenous configuration. Two (20%) patients were successfully liberated from ECMO support after 7 and 10 days, respectively, and one (10%) patient is currently on a weaning course. One patient (10%) died after 9 days on ECMO from multiorgan dysfunction. CONCLUSIONS: These preliminary multi-institutional data from a statewide collaborative offer insight into the clinical characteristics of the first 10 patients requiring ECMO for COVID-19 and their initial clinical course. Greater morbidity and mortality is likely to be seen in these critically ill patients with longer follow-up.

Cardiac surgery considerations and lessons learned during the COVID-19 pandemic

Abstract The COVID-19 pandemic has transformed cardiac surgical practices. Limitations in intensive care resources and personal protective equipment have required many practices throughout the globe to pause elective operations and now slowly resume operations. However, much of cardiac surgery is not elective and patients continue to require surgery on an urgent or emergent basis during the pandemic. This continued need for providing surgical services has introduced several unique considerations ranging from how to prioritize surgery, how to ensure safety for cardiac surgical teams, and how best to resume elective operations to ensure the safety of patients. Additionally, the COVID-19 pandemic has required a careful analysis of how best to carry out heart transplantation, extra-corporeal membrane oxygenation, and congenital heart surgery. In this review, we present the many areas of multidisciplinary consideration, and the lessons learned that have allowed us to carry out cardiac surgery with excellence during the COVID-19 pandemic. As various states experience plateaus, declines, and rises in COVID-19 cases, these considerations are particularly important for cardiac surgical programs throughout the globe.
