The agents most likely to be used in bioterrorism attacks are reviewed, along with the clinical syndromes they produce and their treatment.

Absorbing citywide patient surge during Hurricane Sandy: a case study in accommodating multiple hospital evacuations.

STUDY OBJECTIVE Hospital evacuations have myriad effects on all elements of the health care system. We seek to (1) examine the effect of patient surge on hospitals that received patients from evacuating hospitals in New York City during Hurricane Sandy; (2) describe operational challenges those hospitals faced pre- and poststorm; and (3) examine the coordination efforts to distribute patients to receiving hospitals. METHODS We used a qualitative, interview-based method to identify medical surge strategies used at hospitals receiving patients from evacuated health care facilities during and after Hurricane Sandy. We identified 4 hospital systems that received the majority of evacuated patients and those departments most involved in managing patient surge. We invited key staff at those hospitals to participate in on-site group interviews. RESULTS We interviewed 71 key individuals. Although all hospitals had emergency preparedness plans in place before Hurricane Sandy, we identified gaps. Insights gleaned included improvement opportunities in these areas: prolonged increased patient volume, an increase in the number of methadone and dialysis patients, ability to absorb displaced staff, the challenges associated with nursing homes that have evacuated and shelters that have already reached capacity, and reimbursements for transferred patients. CONCLUSION Our qualitative, event-based research identified key opportunities to improve disaster preparedness. The specific opportunities and this structured postevent approach can serve to guide future disaster planning and analyses.

Mass Vaccination for the 2009 H1N1 Pandemic: Approaches, Challenges, and Recommendations

The 2009 H1N1 pandemic stimulated a nationwide response that included a mass vaccination effort coordinated at the federal, state, and local levels. This article examines a sampling of state and local efforts during the pandemic in order to better prepare for future public health emergencies involving mass distribution, dispensing, and administration of medical countermeasures. In this analysis, the authors interviewed national, state, and local leaders to gain a better understanding of the accomplishments and challenges of H1N1 vaccination programs during the 2009-10 influenza season. State and local health departments distributed and administered H1N1 vaccine using a combination of public and private efforts. Challenges encountered during the vaccination campaign included the supply of and demand for vaccine, prioritization strategies, and local logistics. To improve the response capabilities to deal with infectious disease emergencies, the authors recommend investing in technologies that will assure a more timely availability of the needed quantities of vaccine, developing local public health capacity and relationships with healthcare providers, and enhancing federal support of state and local activities. The authors support in principle the CDC recommendation to vaccinate annually all Americans over 6 months of age against seasonal influenza to establish a standard of practice on which to expand the ability to vaccinate during a pandemic. However, expanding seasonal influenza vaccination efforts will be an expensive and long-term investment that will need to be weighed against anticipated benefits and other public health needs. Such investments in public health infrastructure could be important for building capacity and practice for distributing, dispensing, and administering countermeasures in response to a future pandemic or biological weapons attack.

A Survey of Hospitals to Determine the Prevalence and Characteristics of Healthcare Coalitions for Emergency Preparedness and Response

Previous reports have identified the development of healthcare coalitions as the foundation for disaster response across the United States. This survey of acute care hospitals characterizes the current status of participation by US hospitals in healthcare coalitions for emergency preparedness planning and response. The survey results show the nearly universal nature of a coalition approach to disaster response. The results suggest a need for wide stakeholder involvement but also for flexibility in structure and organization. Based on the survey results, the authors make recommendations to guide the further development of healthcare coalitions and to improve local and national response to disasters.

Assessment of Serosurveys for H5N1

BACKGROUND It has been suggested that the true case-fatality rate of human H5N1 influenza infection is appreciably less than the figure of approximately 60% that is based on official World Health Organization (WHO)-confirmed case reports because asymptomatic cases may have been missed. A number of seroepidemiologic studies have been conducted in an attempt to identify such missed cases. METHODS We conducted a comprehensive literature review of all English-language H5N1 human serology surveys with detailed attention to laboratory methodology used (including whether investigators used criteria set by the WHO to define positive cases), laboratory controls used, and the clades/genotypes involved. RESULTS Twenty-nine studies were included in the analysis. Few reported using unexposed control groups and one-third did not apply WHO criteria. Of studies that used WHO criteria, only 4 found any seropositive results to clades/genotypes of H5N1 that are currently circulating. No studies reported seropositive results to the clade 2/genotype Z viruses that have spread throughout Eurasia and Africa. CONCLUSIONS This review suggests that the frequency of positive H5 serology results is likely to be low; therefore, it is essential that future studies adhere to WHO criteria and include unexposed controls in their laboratory assays to limit the likelihood of false-positive results.

A Primer on Ebola for Clinicians

The size of the worlds largest Ebola outbreak now ongoing in West Africa makes clear that further exportation of Ebola virus disease to other parts of the world will remain a real possibility for the indefinite future. Clinicians outside of West Africa, particularly those who work in emergency medicine, critical care, infectious diseases, and infection control, should be familiar with the fundamentals of Ebola virus disease, including its diagnosis, treatment, and control. In this article we provide basic information on the Ebola virus and its epidemiology and microbiology. We also describe previous outbreaks and draw comparisons to the current outbreak with a focus on the public health measures that have controlled past outbreaks. We review the pathophysiology and clinical features of the disease, highlighting diagnosis, treatment, and hospital infection control issues that are relevant to practicing clinicians. We reference official guidance and point out where important uncertainty or controversy exists.

Surge Capacity Logistics: Care of the Critically Ill and Injured During Pandemics and Disasters: CHEST Consensus Statement

BACKGROUND Successful management of a pandemic or disaster requires implementation of preexisting plans to minimize loss of life and maintain control. Managing the expected surges in intensive care capacity requires strategic planning from a systems perspective and includes focused intensive care abilities and requirements as well as all individuals and organizations involved in hospital and regional planning. The suggestions in this article are important for all involved in a large-scale disaster or pandemic, including front-line clinicians, hospital administrators, and public health or government officials. Specifically, this article focuses on surge logistics-those elements that provide the capability to deliver mass critical care. METHODS The Surge Capacity topic panel developed 23 key questions focused on the following domains: systems issues; equipment, supplies, and pharmaceuticals; staffing; and informatics. Literature searches were conducted to identify studies upon which evidence-based recommendations could be made. The results were reviewed for relevance to the topic, and the articles were screened by two topic editors for placement within one of the surge domains noted previously. Most reports were small scale, were observational, or used flawed modeling; hence, the level of evidence on which to base recommendations was poor and did not permit the development of evidence-based recommendations. The Surge Capacity topic panel subsequently followed the American College of Chest Physicians (CHEST) Guidelines Oversight Committees methodology to develop suggestion based on expert opinion using a modified Delphi process. RESULTS This article presents 22 suggestions pertaining to surge capacity mass critical care, including requirements for equipment, supplies, and pharmaceuticals; staff preparation and organization; methods of mitigating overwhelming patient loads; the role of deployable critical care services; and the use of transportation assets to support the surge response. CONCLUSIONS Critical care response to a disaster relies on careful planning for staff and resource augmentation and involves many agencies. Maximizing the use of regional resources, including staff, equipment, and supplies, extends critical care capabilities. Regional coalitions should be established to facilitate agreements, outline operational plans, and coordinate hospital efforts to achieve predetermined goals. Specialized physician oversight is necessary and if not available on site, may be provided through remote consultation. Triage by experienced providers, reverse triage, and service deescalation may be used to minimize ICU resource consumption. During a temporary loss of infrastructure or overwhelmed hospital resources, deployable critical care services should be considered.

A conceptual approach to improving care in pandemics and beyond: Severe lung injury centers

The events of the 2009 influenza pandemic sparked discussion regarding the need to optimize delivery of care to those most severely ill. We propose in this conceptual study that a tiered regionalization care system be instituted for patients with severe acute respiratory distress syndrome. Such system would be a component of national pandemic plans and could also be used in day-to-day operations.

Biosurveillance Where It Happens: State and Local Capabilities and Needs

In recent years, improved biosurveillance has become a bipartisan national security priority. As has been pointed out by the National Biosurveillance Advisory Subcommittee and others, building a national biosurveillance enterprise requires having strong biosurveillance systems at the state and local levels, and additional policies are needed to strengthen their biosurveillance capabilities. Because of the foundational role that state and local health departments play in biosurveillance, we sought to determine to what extent state and local health departments have the right capabilities in place to provide the information needed to detect and manage an epidemic or public health emergency-both for state and local outbreak management and for reporting to federal agencies during national public health crises. We also sought to identify those policies or actions that would improve state and local biosurveillance and make recommendations to federal policymakers who are interested in improving national biosurveillance capabilities.

Resource-Poor Settings: Infrastructure and Capacity Building: Care of the Critically Ill and Injured During Pandemics and Disasters: CHEST Consensus Statement

BACKGROUND Planning for mass critical care (MCC) in resource-poor or constrained settings has been largely ignored, despite their large populations that are prone to suffer disproportionately from natural disasters. Addressing MCC in these settings has the potential to help vast numbers of people and also to inform planning for better-resourced areas. METHODS The Resource-Poor Settings panel developed five key question domains; defining the term resource poor and using the traditional phases of disaster (mitigation/preparedness/response/recovery), literature searches were conducted to identify evidence on which to answer the key questions in these areas. Given a lack of data upon which to develop evidence-based recommendations, expert-opinion suggestions were developed, and consensus was achieved using a modified Delphi process. RESULTS The five key questions were then separated as follows: definition, infrastructure and capacity building, resources, response, and reconstitution/recovery of host nation critical care capabilities and research. Addressing these questions led the panel to offer 33 suggestions. Because of the large number of suggestions, the results have been separated into two sections: part 1, Infrastructure/Capacity in this article, and part 2, Response/Recovery/Research in the accompanying article. CONCLUSIONS Lack of, or presence of, rudimentary ICU resources and limited capacity to enhance services further challenge resource-poor and constrained settings. Hence, capacity building entails preventative strategies and strengthening of primary health services. Assistance from other countries and organizations is needed to mount a surge response. Moreover, planning should include when to disengage and how the host nation can provide capacity beyond the mass casualty care event.
