Emergency department (ED) visit volumes have increased since 2007, with crowding in the United States reaching its highest levels in 2022. During this same period, mass casualty incidents (MCIs) have increased dramatically, both in frequency and severity, across the United States. Resuscitation of trauma patients is a time-sensitive process that requires immediate patient assessment by coordinated clinical teams in order to successfully diagnose and manage life-threatening injuries. To make resuscitation spaces immediately available for incoming patients, typical MCI plans call for rapidly relocating ED patients from their rooms into hallways or transferring them to open inpatient areas. With current levels of crowding, however, such alternate care spaces are often already in use and traditional MCI plans are increasingly unrealistic. With ED crowding worsening and the frequency of MCIs rising, there is a worrisome risk that EDs could fail in their efforts to save patients due to insufficient resources and spaces to meet the demands of critically injured patients. Hospitals must use innovative, novel response strategies to ensure sufficient patient care spaces in a short timeframe to save the most lives possible. In this commentary, we describe the use of buffer zones to help EDs mobilize an effective response to MCIs in the current context of severe hospital crowding.

We led the last large-scale exercise conducted by the Johns Hopkins Center for Health Security before the COVID-19 pandemic. Despite COVID-19, pandemic exercises are more necessary than ever to prevent the loss of hard-fought gains achieved during COVID-19, keep policymakers from assuming all pandemics will be like COVID-19, and encourage continued engagement from policymakers in strengthening health resilience rather than returning to a cycle of panic and neglect. Pandemic exercises can also advance new solutions necessary to effectively meet the challenge of a future pandemic. Over 2 decades, the Johns Hopkins Center for Health Security has developed and conducted 6 large-scale, high-level tabletop pandemic exercises. These exercises and others were designed to increase policy focus on the most critical needs in pandemic preparedness and heighten the urgency for making these changes in the near future. Pandemic experts and policymakers alike have highlighted the importance of exercises to ensure that all key actors involved in pandemic response-including the government, healthcare, public health, emergency response, and private business and industry sectors-understand both the best practices and policies to pursue before a pandemic and what to do once a pandemic occurs. These advance efforts can enhance planning, resource allocation, and coordination ahead of time and identify unique gaps and barriers. This commentary describes the approach we have developed to create and conduct such exercises and highlights key considerations that were important to successful outcomes.

A high-level isolation unit (HLIU) is a specially designed biocontainment unit for suspected or confirmed high-consequence infectious diseases. For most HLIUs, maintaining readiness during times of inactivity is a challenge. In this case study, we describe a checklist approach to assess HLIU readiness to rapidly operate upon activation. This checklist includes readiness criteria in several domains, such as infrastructure, human resources, and material supplies, that are required to safely activate the unit at any time. The checklist audit tool was derived from a novel activation readiness checklist published by the biocontainment unit at The Johns Hopkins Hospital in Baltimore, Maryland. It was then adapted for the Irish healthcare setting and implemented at the Mater Misericordiae University Hospital, Ireland's current isolation facility. Results from the audit were also used to inform recommendations for the construction of a new HLIU to open in 2025. The audit tool is user friendly, practical, and focuses on the essential elements of readiness to ensure a successful rapid operation.

An important aspect of microbiological surveillance is the ability to access live viruses for microneutralization assays, which enables the study of viral characteristics and mechanisms in vitro and production of positive controls for diagnostic methods. During the COVID-19 pandemic, the Public Health Agency of Sweden established a protocol for the rapid collection of clinical samples and subsequent isolation of novel virus variants.

Infectious disease physicians in England have been diagnosing and managing occasional cases of viral hemorrhagic fever since 1971, including the United Kingdom's first case of Ebola virus disease in 1976. Specialist isolation facilities to provide safe and effective care have been present since that time. Following the emergence of Middle East respiratory syndrome (MERS) in 2012, and the avian influenza A (H7N9) outbreak in 2013, and the 2014-2016 Ebola virus disease outbreak in West Africa, clinical and public health preparedness and response pathways in England have been strengthened for these types of diseases, now called high-consequence infectious diseases (HCIDs). The HCID program, led by NHS England and Public Health England between 2016 and 2018, helped to deliver these enhancements, which have since been used on multiple occasions for new UK cases and outbreaks of MERS, mpox, avian influenza, and Lassa fever. Additionally, HCID pathways were activated for COVID-19 during the first 3 months of 2020, before the pandemic had been declared and little was known about COVID-19 but HCID status had been assigned temporarily to COVID-19 as a precaution. The HCID program also led to the commissioning of a network of new airborne HCID treatment centers in England, to supplement the existing network of contact HCID treatment centers, which includes the United Kingdom's only 2 high-level isolation units. In this case study, the authors describe the airborne and contact HCID treatment center networks in England, including their formation and structures, their approach to safe and effective clinical management of patients with HCIDs in the United Kingdom, and challenges they may face going forward.

In response to the growing number of outbreaks of emerging infectious diseases, the US Administration for Strategic Preparedness and Response (ASPR) has embarked on a plan to improve and expand special pathogen patient care capabilities. To achieve this, ASPR is developing a coordinated network of Regional Emerging Special Pathogen Treatment Centers (RESPTCs) to serve as state-of-the-art facilities staffed by a highly trained workforce to care for and manage special pathogen patients across the lifespan. The RESPTC network represents the operational arm of a broader US National Special Pathogen System of care to prevent and prepare for the next infectious disease outbreak. RESPTCs are strategically located in every region across the country and form a network linking local and regional healthcare partners to enhance national preparedness through training in best practices for detection, isolation, and treatment of individuals suspected of or known to be infected with a special pathogen. This local, regional, and national network is also designed to lead a coordinated response that includes the dissemination of accurate and trustworthy information to responders and the public. The overarching goal of the RESPTCs is to serve as a valuable resource for clinical care, training, and material support to meet current and future major infectious diseases challenges. In this case study, 2 new RESPTCs, MedStar Washington Hospital Center and the University of North Carolina, describe their experiences related to designing a biocontainment unit, creating clinical teams, building staff resiliency, receiving mentoring from regional RESPTC partners, and developing opportunities for innovation.
