Anesthetic Resource Limitations and Adaptations in Times of Shortage: Experiences from New York Presbyterian Hospital During COVID-19.

In March 2020, the COVID-19 pandemic reached New York City, resulting in thousands of deaths over the following months. Because of the exponential spread of disease, the New York City hospital systems became rapidly overwhelmed. The Department of Anesthesiology at New York Presbyterian (NYP)-Columbia continued to offer anesthesia services for obstetrics and emergency surgery, while redirecting the rest of its staff to the expanded airway management role and the creation of the largest novel intensive care unit in the NYP system. Tremendous innovation and optimization were necessary in the face of material, physical, and staffing constraints.

The impact of COVID-19 on anaesthesia and critical care services in the UK: a serial service evaluation.

Between October 2020 and January 2021, we conducted three national surveys to track anaesthetic, surgical and critical care activity during the second COVID-19 pandemic wave in the UK. We surveyed all NHS hospitals where surgery is undertaken. Response rates, by round, were 64%, 56% and 51%. Despite important regional variations, the surveys showed increasing systemic pressure on anaesthetic and peri-operative services due to the need to support critical care pandemic demands. During Rounds 1 and 2, approximately one in eight anaesthetic staff were not available for anaesthetic work. Approximately one in five operating theatres were closed and activity fell in those that were open. Some mitigation was achieved by relocation of surgical activity to other locations. Approximately one-quarter of all surgical activity was lost, with paediatric and non-cancer surgery most impacted. During January 2021, the system was largely overwhelmed. Almost one-third of anaesthesia staff were unavailable, 42% of operating theatres were closed, national surgical activity reduced to less than half, including reduced cancer and emergency surgery. Redeployed anaesthesia staff increased the critical care workforce by 125%. Three-quarters of critical care units were so expanded that planned surgery could not be safely resumed. At all times, the greatest resource limitation was staff. Due to lower response rates from the most pressed regions and hospitals, these results may underestimate the true impact. These findings have important implications for understanding what has happened during the COVID-19 pandemic, planning recovery and building a system that will better respond to future waves or new epidemics.

Psychological distress during the acceleration phase of the COVID-19 pandemic: a survey of doctors practising in emergency medicine, anaesthesia and intensive care medicine in the UK and Ireland.

OBJECTIVE: To quantify psychological distress experienced by emergency, anaesthetic and intensive care doctors during the acceleration phase of COVID-19 in the UK and Ireland. METHODS: Initial cross-sectional electronic survey distributed during acceleration phase of the first pandemic wave of COVID-19 in the UK and Ireland (UK: 18 March 2020-26 March 2020 and Ireland: 25 March 2020-2 April 2020). Surveys were distributed via established specialty research networks, within a three-part longitudinal study. Participants were doctors working in emergency, anaesthetic and intensive medicine during the first pandemic wave of COVID-19 in acute hospitals across the UK and Ireland. Primary outcome measures were the General Health Questionnaire-12 (GHQ-12). Additional questions examined personal and professional characteristics, experiences of COVID-19 to date, risk to self and others and self-reported perceptions of health and well-being. RESULTS: 5440 responses were obtained, 54.3% (n=2955) from emergency medicine and 36.9% (n=2005) from anaesthetics. All levels of doctor seniority were represented. For the primary outcome of GHQ-12 score, 44.2% (n=2405) of respondents scored >3, meeting the criteria for psychological distress. 57.3% (n=3045) had never previously provided clinical care during an infectious disease outbreak but over half of respondents felt somewhat prepared (48.6%, n=2653) or very prepared (7.6%, n=416) to provide clinical care to patients with COVID-19. However, 81.1% (n=4414) either agreed (31.1%, n=2709) or strongly agreed (31.1%, n=1705) that their personal health was at risk due to their clinical role. CONCLUSIONS: Findings indicate that during the acceleration phase of the COVID-19 pandemic, almost half of frontline doctors working in acute care reported psychological distress as measured by the GHQ-12. Findings from this study should inform strategies to optimise preparedness and explore modifiable factors associated with increased psychological distress in the short and long term.

Analysis of anaesthesia services to calculate national need and supply of anaesthetics in Switzerland during the COVID-19 pandemic.

BACKGROUND: In Switzerland, details of current anaesthesia practice are unknown. However, they are urgently needed to manage anaesthesia drug supply in times of drug shortages due to the pandemic. METHODS: We surveyed all Swiss anaesthesia institutions in April 2020 to determine their annual anaesthesia activity. Together with a detailed analysis on anaesthetic drug use of a large, representative Swiss anaesthesia index institution, calculations and projections for the annual need of anaesthetics in Switzerland were made. Only those drugs have been analysed that are either being used very frequently or that have been classified critical with regard to their supply by the pharmacy of the index institution or the Swiss Federal Office of Public Health. RESULTS: The response rate to our questionnaire was 98%. Out of the present 188 Swiss anaesthesia institutions, 185 responded. In Switzerland, the annual number of anaesthesias was 1'071'054 (12'445 per 100'000 inhabitants) with a mean anaesthesia time of 2.03 hours. Teaching hospitals (n = 54) performed more than half (n = 572'231) and non-teaching hospitals (n = 103) provided almost half of all anaesthesias (n = 412'531). Thereby, private hospitals conducted a total of 290'690 anaesthesias. Finally, office-based anaesthesia institutions with mainly outpatients (n = 31) administered 86'292 anaesthesias. Regarding type of anaesthesia provided, two thirds were general anaesthesias (42% total intravenous, 17% inhalation, 8% combined), 20% regional and 12% monitored anaesthesia care. Projecting for example the annual need for propofol in anaesthesia, Switzerland requires 48'573 L of propofol 1% which corresponds to 5'644 L propofol 1% per 100'000 inhabitants every year. CONCLUSIONS: To actively manage anaesthesia drug supply in the context of the current pandemic, it is mandatory to have a detailed understanding of the number and types of anaesthesias provided. On this basis, the Swiss annual consumption of anaesthetics could be projected and the replenishment organized.

Review of Anesthesia Versus Intensive Care Unit Ventilators and Ventilatory Strategies: COVID-19 Patient Management Implications.

The coronavirus disease 2019 (COVID-19) respiratory illness has increased the amount of people needing airway rescue and the support of mechanical ventilators. In doing so, the pandemic has increased the demand of healthcare professionals to manage these critically ill individuals. Certified Registered Nurse Anesthetists (CRNAs), who are trained experts in airway management and mechanical ventilation with experience in intensive care units (ICUs), rise to this challenge. However, many CRNAs may be unfamiliar with advancements in critical care ventilators. The purpose of this review is to provide a resource for CRNAs returning to the ICU to manage patients requiring invasive mechanical ventilation. The most common ventilator modes found in anesthesia machine ventilators and ICU ventilators are reviewed, as are the lung-protective ventilation strategies, including positive end-expiratory pressure, used to manage patients with COVID-19-induced acute respiratory distress syndrome. Adjuncts to mechanical ventilation, recruitment maneuvers, prone positioning, and extracorporeal membrane oxygenation are also reviewed. More research is needed concerning the management of COVID-19-infected patients, and CRNAs must become familiar with their ICU units' individual ventilator machine, but this brief review provides a good place to start for those returning to the ICU.
