Increased incidence of post-operative respiratory failure in patients with pre-operative SARS-CoV-2 infection.

OBJECTIVE: While studies have reported increased post-operative pulmonary complications with SARS-CoV-2 infection, many are limited by use of historical controls or focus on less severe respiratory complications. We characterized the association between pre-operative SARS-CoV-2 infection and post-operative respiratory failure (PORF). DESIGN AND SETTING: This was a single center retrospective cohort study in New York City between March 14-June 14, 2020. PATIENTS: Exclusion criteria were age < 18-years, obstetric procedures, absence of SARS-CoV-2 PCR testing, and pre-operative respiratory failure. A total of 778 patients met criteria, of which 87 had SARS-CoV-2. MEASUREMENTS: The primary outcome, PORF, included inability to extubate for ≥24 h or unplanned re-intubation within 5 days. Multiple exposures were measured including SARS-CoV-2 infection 4 weeks before or 5 days after surgery. Multivariable logistic regression was performed to adjust for pre-operative hypoxemia, oxygen use, and pneumonia as well as tachycardia, gender, Charlson Comorbidity Index (CCI), Surgical Mortality Probability Model (S-MPM) index, and peri-operative blood transfusion. MAIN RESULTS: SARS-CoV patients had higher CCI (P = 0.007) and S-MPM scores (P = 0.02). The incidence of PORF was 16% versus 7% in uninfected comparators (P = 0.001). Amongst infected individuals, 39% exhibited symptoms of COVID-19 and PORF was more common in these patients compared to asymptomatic individuals (26% vs. 9%, P = 0.04). Adjusted analysis revealed increased odds of PORF with infection (OR 2.8, 95% CI 1.2-6.2). This persisted even when adjusting for probable mediators such as pre-operative hypoxemia. Infected patients also demonstrated increased adjusted odds of 30-day mortality (OR 3.5, 95% CI 1.4-9.1). CONCLUSIONS: Detection of SARS-CoV-2 infection within 4 weeks before or 5 days after surgery is associated with increased odds of 5-day PORF and 30-day mortality. This supports delaying elective surgery, but questions remain regarding the applicability of this recommendation for asymptomatic patients needing urgent or semi-urgent procedures such as oncologic surgery.

Anesthesiology Training in the Time of COVID-19: Problems and Solutions.

From March to June of 2020, Montefiore Medical Center faced one of the most acute surges in hospital admissions and critical illness ever experienced in the United States due to the severe acute respiratory syndrome coronavirus 2 pandemic. The pandemic had not yet spread to most of the country, and there was a relative deficit of knowledge regarding treatments, prognosis, and prevention of the virus, making this experience relatively unique and challenging. As part of a surge plan, our institution converted nonclinical spaces, such as conference rooms, to inpatient care settings and placed elective surgeries on hold to free up resources. A central deployment office suspended anesthesiology resident rotations and instead assigned them to intensive care settings based on need. For the Montefiore Medical Center Department of Anesthesiology, preserving its academic mission and commitment to Graduate Medical Education was essential. Adaptations included changing the residency rotation structure to biweekly, converting didactics online, ensuring adequate case numbers for graduating residents, actively pursuing wellness interventions, and prioritizing the safety of the residents caring for patients with coronavirus disease 2019 (COVID-19). In this brief report, the authors discuss solutions devised to maintain the quality of anesthesiology resident education and training as much as possible during the COVID-19 surge.

Adaptation and restructuring of an academic anesthesiology department during the COVID-19 pandemic in New York City: Challenges and lessons learned.

The novel SARS-CoV-2 pandemic starting in 2019 profoundly changed the world, and thousands of residents of New York City were affected, leading to one of the most acute surges in regional hospital capacity. As the largest academic medical center in the Bronx, Montefiore Medical Center was immediately impacted, and the entire hospital was mobilized to address the needs of its community. In this article, we describe our experiences as a large academic anesthesiology department during this pandemic. Our goals were to maximize our staff's expertise, maintain our commitment to wellness and safety, and preserve the quality of patient care. Lessons learned include the importance of critical care training presence and leadership, the challenges of converting an ambulatory surgery center to an intensive care unit (ICU), and the management of effective communication. Lastly, we provide suggestions for institutions facing an acute surge, or subsequent waves of COVID-19, based on a single center's experiences.
