Planning for the Use of Imaging in Mass Casualty Incidents

Introduction:A mass casualty incident presents a challenging situation in any health care setting. The value of preparation and planning for mass casualty incidents has been widely reported in the literature. The benefit of imaging, in particular, forensic radiography, in these situations is also reported. Despite this, the inclusion of detailed planning on the use of forensic radiography is an observed gap in disaster preparedness documentation.Aim:To identify the role of forensic radiography in mass casualty incidents and to explore the degree of inclusion of forensic radiography in publicly available disaster planning documents.Methods:An extended literature review was undertaken to identify examples of forensic radiography in mass casualty incidents, and to determine the degree of inclusion of forensic radiography in publicly available disaster planning documents. Where included, the activity undertaken by forensic radiography was reviewed in relation to the detail of the planning information.Results:Limited results were identified of disaster planning documents containing detail of the role or planned activity for forensic radiography.Discussion:While published accounts of situation debriefing and lessons learned from past mass casualty incidents provide evidence for integration into future planning activities, limited reports were identified with the inclusion of forensic radiography. This presentation provides an overview of the roles of forensic radiography in mass casualty incidents. The specific inclusion of planning for the use of imaging in mass fatality incidents is recommended.

Trends in United States Mass Fatality Incidents and Recommendations for Medical Examiners and Coroners

It is imperative that medicolegal jurisdictions prepare for the occurrence of a mass fatality incident. Despite the trend to plan for catastrophic and complicated incidents, this analysis of recent mass fatality events seeks to better inform authorities regarding the scale and types of incidents that could potentially impact their jurisdiction. The guidance provided by this study serves as a tool to guide the development of plans, acquisition of appropriate resources, and training of staff. To perform this analysis, data were collected from mass fatality incidents occurring in the United States from January 1, 2000 to December 31, 2016 that resulted in ten or more fatalities. Specific data points were collected for each incident including the date, location, number of fatalities, incident type (e.g., man-made or natural), incident subtype, and description (e.g., mass shooting, hurricane, aviation). A total of 137 incidents fit the criteria for inclusion in the analysis, resulting in a total of 8462 fatalities. The average number of incidents was eight per year during the study period. The analysis demonstrates that most mass fatality incidents (88.8%) result in between ten and 50 fatalities and are variable based on incident type and geographic location. This study includes several large-scale incidents, which as outliers have influenced fatality management operations and preparedness efforts on a national level. In particular, the World Trade Center attack of September 11, 2001 and subsequent remains recovery and identification operations have served to inform the New York City Office of Chief Medical Examiner of the capabilities required to manage a complex, protracted victim identification process involving extensive body fragmentation and commingling. While the World Trade Center attack has been shown to be outside the normal trends of mass fatality incidents, it has nonetheless offered the medicolegal community several invaluable lessons.

A New Morphological Trait in Forensic Identification – Middle Phalangeal Hair (MPH)

Middle phalangeal hairs (MPH) are present on the dorsal aspect of the middle phalange of the fingers except for the thumb. The MPH have been of interest to anthropologists, human biologists, clinicians, geneticists and anatomists in the past as a morphological trait of the human body. The anthropological value of MPH is well established in studying population variations, with implications for age, ancestry and sex differences. We are of the opinion that MPH may be used significantly for forensic identification purposes along with other morphological characteristics of the human body. MPH can be one of the individualistic features in comparing the ante-mortem and post-mortem records in mass fatality incidents and in establishing identity in forensic casework pertaining to CCTV images of the hand.

Are We Ready for Mass Fatality Incidents? Preparedness of the US Mass Fatality Infrastructure

ObjectiveTo assess the preparedness of the US mass fatality infrastructure, we developed and tested metrics for 3 components of preparedness: organizational, operational, and resource sharing networks.MethodsIn 2014, data were collected from 5 response sectors: medical examiners and coroners, the death care industry, health departments, faith-based organizations, and offices of emergency management. Scores were calculated within and across sectors and a weighted score was developed for the infrastructure.ResultsA total of 879 respondents reported highly variable organizational capabilities: 15% had responded to a mass fatality incident (MFI); 42% reported staff trained for an MFI, but only 27% for an MFI involving hazardous contaminants. Respondents estimated that 75% of their staff would be willing and able to respond, but only 53% if contaminants were involved. Most perceived their organization as somewhat prepared, but 13% indicated “not at all.” Operational capability scores ranged from 33% (death care industry) to 77% (offices of emergency management). Network capability analysis found that only 42% of possible reciprocal relationships between resource-sharing partners were present. The cross-sector composite score was 51%; that is, half the key capabilities for preparedness were in place.ConclusionsThe sectors in the US mass fatality infrastructure report suboptimal capability to respond. National leadership is needed to ensure sector-specific and infrastructure-wide preparedness for a large-scale MFI. (Disaster Med Public Health Preparedness. 2016;10:87–97)
