In this article, we detail a comprehensive laboratory evaluation of an immunoassay for the rapid detection of ricin using the Meso Scale Diagnostics Sector PR2 Model 1800. For the assay evaluation, we used inclusivity, exclusivity, and informational panels comprised of extracts of 35 near-neighbor plant cultivar-extracts, 66 lectins, 26 white powders, 16 closely related toxins and proteins/toxoids, and a pool of 30 BioWatch filter extracts. The results show that the Meso Scale Diagnostics ricin detection assay exhibits good sensitivity and specificity with a limit of detection of 1.2 ng/mL. However, the dynamic range of the assay for the quantitation of ricin was limited. We observed a hook effect at higher ricin concentrations, which can lead to potential false negative results. A modification of the assay protocol that incorporates extra wash steps can decrease the hook effect and the potential for false negative results.

Patients with high-consequence infectious diseases (HCIDs) require high-quality care by specially trained staff in a high-level isolation unit (HLIU) that follows strict infection prevention and control (IPC) measures. Caring for patients with (suspected) HCID is challenging, mainly because of the strict personal protective equipment (PPE) and IPC protocols healthcare workers (HCW) must adhere to for protection. The Radboud University Medical Center, located in Nijmegen, the Netherlands, has been a dedicated HLIU facility since 2008. A newly built HLIU opened in May 2022, and encouraged us to review the existing PPE selection, IPC protocols, and HCID training program to improve safety and comfort for HCWs working in the HLIU. Based on a systematic search through (inter)national HCID PPE guidelines and semistructured interviews with end users, we selected an improved, more comfortable set of PPE. Additionally, we developed a more concise and easier-to-use patient care process flow and implemented a new teaching strategy. The new way of working was tested in October 2022 when the first 2 patients with suspected HCID were admitted to our unit. We used surveys to evaluate the experiences of HCWs involved in this care to further improve the workflow of the unit. When optimizing safety and comfort for HCWs, it is important to consider (inter)national guidelines as well as user preferences. By systematically evaluating recent experiences of patient admission to the HLIU and then adjusting protocols and training, we can ensure that the quality of provided healthcare and the safety of HCWs working in the HLIU remains high.

This case study describes a feasibility assessment of a novel isolation care tent used in health facilities in Uganda during the 2022 Sudan ebolavirus outbreak. The Isolation System for Treatment and Agile Response to High-Risk Infections Model 1B (ISTARI 1B) is a single-occupancy, portable, negative-pressure isolation tent designed for the safe delivery of standard care to patients with a communicable disease, including Ebola disease (Sudan). At the request of the Uganda Ministry of Health, the Makerere University Infectious Diseases Institute and University of Nebraska Medical Center partnered to evaluate 7 health facilities across 4 districts in Uganda for infrastructure, case management, and infection prevention and control (IPC) capacity relevant to isolation care and ISTARI 1B use. A 3-day workshop was held with IPC leaders to provide familiarization and hands-on experience with the ISTARI 1B, delineate appropriate use scenarios in Ugandan healthcare settings, contextualize ISTARI 1B use in case management and IPC workflows, develop a framework for site assessment and implementation readiness, and consider ongoing monitoring, assessment, and intervention tools. Workshop participants performed a comprehensive site assessment and mock deployment of the ISTARI 1B. In this case study, we describe lessons learned from health facility assessments and workshop outcomes and offer recommendations to support successful ISTARI 1B implementation. Use scenarios and implementation strategies were identified across facility levels, including tools for site assessment, training, risk communication, and ongoing quality and safety monitoring.

Infection of Western aid workers with Ebola virus disease during the 2014-2016 West African outbreak demonstrated the need for medical evacuation to high-level isolation units in Europe and the United States. In Norway, an ad hoc preparedness team was established for aeromedical evacuation in case of need. In October 2014, this team transported an infected aid worker from the military section of Oslo Airport to Oslo University Hospital. To maintain and strengthen the capacity for domestic ambulance transport on the ground and in the air, the Norwegian Medical Emergency Response Team for High Consequence Infectious Diseases (in Norway known as "Nasjonalt medisinsk utrykningsteam for høyrisikosmitte"), or NORTH, was established as a permanent service in 2017. Recognizing the expertise of this domestic team, Norway was subsequently entrusted with the task of enhancing the European aeromedical transport capacity for high-consequence infectious diseases and establishing the Norwegian rescEU Jet Air Ambulance for Transport of Highly Infectious Patients, or NOJAHIP, in 2022. In this case study, we present experiences and lessons learned from these 2 services and discuss how they can be further developed.

The New South Wales Biocontainment Centre is a statewide referral facility for patients with high-consequence infectious disease (HCID). The facility collaborates with researchers to adapt existing HCID procedures such as donning and doffing of personal protective equipment (PPE). However, information on how to respond safely to collapse of a healthcare provider in full PPE within a contaminated zone is scarce. To address this gap, we adapted Nebraska Medicine's "provider down" protocol on paper and then simulated and video recorded the process, iteratively, in the facility. Clinicians analyzed the recordings collaboratively in researcher-facilitated reflexive discussions. Our primary aim was to ascertain how to maintain optimal infection prevention and control while providing urgent care for the healthcare provider. We tested participants' suggested modifications, in repeated video recorded simulations, until consensus on optimal practice was achieved. Our secondary aim was to assess the utility of video-reflexive methods to enhance clinicians' awareness and understanding of infection prevention and control in a rare and complex scenario. Six adaptations and simulations were discussed in video-reflexive sessions before consensus was reached; the final version of the protocol differed considerably from the first. Viewing footage of simulations in situ enabled participants to (1) identify infection and occupational risks not identified on paper or during verbal postsimulation debriefs and (2) test alternative perspectives on safe procedure. Video-reflexivity enables context-sensitive and consensus-building codesign of policies and procedures, critical to protocol development in a new unit. It contributes to a culture of teamwork, preparedness, and confidence before, rather than in the heat of, a crisis.

Although first aid research is a wide-ranging and diverse field within medical science, so far no attempts have been made to provide a holistic view of international scientific outputs in the first aid domain. To determine strategic directions for conducting future studies, it is important to understand the status of the research, including its frontiers and blind spots. This study explored the global landscape of first aid research using bibliometric visualization analysis of relevant literature published within the last 20 years. The search yielded a total of 2,057 relevant papers. There was a trend of increasing annual numbers of publications throughout the 20 year period. The following topics were identified as the mainstream directions of first aid research: cross-sectional studies on attitudes and knowledge of first aid; cardiac arrest and cardiopulmonary resuscitation; bleeding and hemorrhage control; burns, scalds, and their management; envenomations and their management; and systematic evaluation of the scientific evidence. Evidence evaluation is one of the main frontiers of first aid research. Studies concerning first aid for the most common and deadliest diseases, including myocardial infarction and stroke, are not in the scope of contemporary international first aid research. Considering that effective implementation of first aid can reduce morbidity and mortality, it is advisable to advance research on first aid management of major emergencies that are the most common potentially avoidable causes of death.

Developing and sustaining relationships and networks before an emergency occurs is crucial. The Biocontainment Unit Leadership Workgroup is a consortium of the 13 Regional Emerging Special Pathogen Treatment Centers in the United States. Established in 2017, the volunteer-based workgroup is composed of operational leaders dedicated to maintaining readiness for special pathogen care. Monthly meetings focus on addressing operational challenges, sharing best practices, and brainstorming solutions to common problems. Task forces are leveraged to tackle more complex issues that are identified as priorities. In 2022, members of the workgroup were harnessed for response efforts related to mpox, Sudan ebolavirus, and Marburg virus disease. The weekly Outbreak Readiness call is a shared effort between the Biocontainment Unit Leadership Workgroup and the Special Pathogens Research Network of the National Emerging Special Pathogens Training and Education Center. Call participants included leaders of the Regional Emerging Special Pathogen Treatment Centers and federal partners who shared weekly updates on operational readiness of units, case counts, laboratory capacity, available medical countermeasures, and other pertinent information. The routine exchange of real-time information enabled learning and collegial sharing of experiences, highlighted the experience of the network to federal partners, and provided situational awareness of special pathogen outbreaks across the country. The consortium enabled this rapid convening of partners to meet an urgent need for special pathogen response. The weekly Outbreak Readiness call is a communication model and scalable framework that serves both domestic preparedness efforts and international efforts should the need for a collaborative global response arise. In this case study, we describe the framework and experience of this partnership, along with the structure of rapid deployment for group convening.

High-level isolation units (HLIUs) have been established by countries to provide safe and optimal medical care for patients with high-consequence infectious diseases. We aimed to identify global high-level isolation capabilities and determine gaps and priorities of global HLIUs, using a multiple method approach that included a systematic review of published and gray literature and a review of Joint External Evaluations and Global Health Security Index reports from 112 countries. A follow-up electronic survey was distributed to identified HLIUs. The landscape analysis found 44 previously designated/self-described HLIUs in 19 countries. An additional 33 countries had potential HLIUs; however, there were not enough details on capabilities to determine if they fit the HLIU definition. An electronic survey was distributed to 36 HLIUs to validate landscape analysis findings and to understand challenges, best practices, and priorities for increased networking with a global HLIU cohort; 31 (86%) HLIUs responded. Responses revealed an additional 30 confirmed HLIUs that were not identified in the landscape analysis. To our knowledge, this was the first mapping and the largest ever survey of global HLIUs. Survey findings identified major gaps in visibility of HLIUs: while our landscape analysis initially identified 44 units, the survey unveiled an additional 30 HLIUs that had not been previously identified or confirmed. The lack of formalized regional or global coordinating organizations exacerbates these visibility gaps. The unique characteristics and capabilities of these facilities, coupled with the likelihood these units serve as core components of national health security plans, provides an opportunity for increased connection and networking to advance the field of high-level isolation and address identified gaps in coordination, build an evidence base for HLIU approaches, and inform HLIU definitions and key components.
