Chemical, Biological, Radiological, Nuclear, and Explosive (CBRNE) Science and the CBRNE Science Medical Operations Science Support Expert (CMOSSE).

A national need is to prepare for and respond to accidental or intentional disasters categorized as chemical, biological, radiological, nuclear, or explosive (CBRNE). These incidents require specific subject-matter expertise, yet have commonalities. We identify 7 core elements comprising CBRNE science that require integration for effective preparedness planning and public health and medical response and recovery.

Cost-Effectiveness of the Use of Autologous Cell Harvesting Device Compared to Standard of Care for Treatment of Severe Burns in the United States.

Introduction: When introducing a new intervention into burn care, it is important to consider both clinical and economic impacts, as the financial burden of burns in the USA is significant. This study utilizes a health economic modeling approach to estimate cost-effectiveness and burn center budget-impact for the use of the RECELL Autologous Cell Harvesting Device to prepare autologous skin cell suspension (ASCS) compared to standard of care (SOC) split-thickness skin graft (STSG) for the treatment of severe burn injuries requiring surgical intervention for definitive closure.

Methods: A hospital-perspective model using sequential decision trees depicts the acute burn care pathway (wound assessment, debridement/excision, temporary coverage, definitive closure) and predicts the relative differences between use of ASCS compared to SOC.

Economic Spillovers From Public Investments in Medical Countermeasures: A Case Study of a Burn Debridement Product.

Objective: The US federal government invests in the development of medical countermeasures for addressing adverse health effects to the civilian population from chemical, biological, and radiological or nuclear threats. We model the potential economic spillover effects in day-to-day burn care for a federal investment in a burn debridement product for responding to an improvised nuclear device.

Methods: We identify and assess 4 primary components for projecting the potential economic spillover benefits of a burn debridement product: (1) market size, (2) clinical effectiveness and cost-effectiveness, (3) product cost, and (4) market adoption rates.

A Conceptual Framework for Allocation of Federally Stockpiled Ventilators During Large-Scale Public Health Emergencies.

Some types of public health emergencies could result in large numbers of patients with respiratory failure who need mechanical ventilation. Federal public health planning has included needs assessment and stockpiling of ventilators. However, additional federal guidance is needed to assist states in further allocating federally supplied ventilators to individual hospitals to ensure that ventilators are shipped to facilities where they can best be used during an emergency.

Assessing the Capacity of the US Health Care System to Use Additional Mechanical Ventilators During a Large-Scale Public Health Emergency.

Objective: A large-scale public health emergency, such as a severe influenza pandemic, can generate large numbers of critically ill patients in a short time. We modeled the number of mechanical ventilators that could be used in addition to the number of hospital-based ventilators currently in use.

Methods: We identified key components of the health care system needed to deliver ventilation therapy, quantified the maximum number of additional ventilators that each key component could support at various capacity levels (ie, conventional, contingency, and crisis), and determined the constraining key component at each capacity level.

Estimates of the demand for mechanical ventilation in the United States during an influenza pandemic.

An outbreak in China in April 2013 of human illnesses due to avian influenza A(H7N9) virus provided reason for US public health officials to revisit existing national pandemic response plans. We built a spreadsheet model to examine the potential demand for invasive mechanical ventilation (excluding "rescue therapy" ventilation). We considered scenarios of either 20% or 30% gross influenza clinical attack rate (CAR), with a "low severity" scenario with case fatality rates (CFR) of 0.

Medical planning and response for a nuclear detonation: a practical guide.

This article summarizes major points from a newly released guide published online by the Office of the Assistant Secretary for Preparedness and Response (ASPR). The article reviews basic principles about radiation and its measurement, short-term and long-term effects of radiation, and medical countermeasures as well as essential information about how to prepare for and respond to a nuclear detonation. A link is provided to the manual itself, which in turn is heavily referenced for readers who wish to have more detail.

User-managed inventory: an approach to forward-deployment of urgently needed medical countermeasures for mass-casualty and terrorism incidents.

The user-managed inventory (UMI) is an emerging idea for enhancing the current distribution and maintenance system for emergency medical countermeasures (MCMs). It increases current capabilities for the dispensing and distribution of MCMs and enhances local/regional preparedness and resilience. In the UMI, critical MCMs, especially those in routine medical use ("dual utility") and those that must be administered soon after an incident before outside supplies can arrive, are stored at multiple medical facilities (including medical supply or distribution networks) across the United States.

Clinical utility of gene-expression profiling for tumor-site origin in patients with metastatic or poorly differentiated cancer: impact on diagnosis, treatment, and survival.

Purpose: The primary tissue-site origin in over 4% of cancers remains uncertain despite thorough clinicopathological evaluation. This study assessed the effect of a Food and Drug Administration-cleared 2,000- gene-expression-profiling (GEP) test on primary tissue-site working diagnoses and management for metastatic and poorly differentiated cancers.

Methods: Clinical information was collected from physicians ordering the GEP test for patients with difficult to diagnose cancers.

Potential clinical utility of gene-expression profiling in identifying tumors of uncertain origin.

Aim: To evaluate the potential impact of a gene-expression-based test on the diagnosis of primary tumors in difficult-to-diagnose cases.

Materials & Methods: The Tissue of Origin Test uses 2000 gene measurements to classify the most likely primary tumor. We categorized 284 consecutive samples by pretest diagnosis, then recategorized the samples using test results to identify cases with changes in diagnosis.

Validation and reproducibility of a microarray-based gene expression test for tumor identification in formalin-fixed, paraffin-embedded specimens.

Tumors whose primary site is challenging to diagnose represent a considerable proportion of new cancer cases. We present validation study results for a gene expression-based diagnostic test (the Pathwork Tissue of Origin Test) that aids in determining the tissue of origin using formalin-fixed, paraffin-embedded (FFPE) specimens. Microarray data files were generated for 462 metastatic, poorly differentiated, or undifferentiated FFPE tumor specimens, all of which had a reference diagnosis.

Physician dispensing: an old idea is new again.

Faced with declining reimbursement for infusional therapies, an oncology practice turned to physician dispensing to offset the loss. Its leaders quickly discovered that the dispensing-vendor landscape was limited, and few guidelines existed for product line development. Yet the approach offers a competitive response to the changing health care landscape.
