Overview
The National Institute of Justice (NIJ)—in partnership with its Forensic Technology Center of Excellence (FTCOE) at RTI International and the National Center for Health Statistics, Centers for Disease Control and Prevention (CDC)—convened a virtual Medicolegal Death Investigation Data Exchange Working Group (MDI-Data-WG) over a 12-month period, beginning in September 2020. This working group was formed to:
- Document the types of data that are commonly exchanged with public health and public safety partners
and determine collective usage points for medicolegal death investigations (MDIs); - Provide recommendations on how to improve the naming process for emerging drugs;
- Guide the drug mapping/classification process; and
- Recommend needed enhancements to the operation of exchanging forensic data with other
organizations.
This document summarizes the opportunities for and challenges of increasing standardization and automation in approaches to collecting and exchanging data among MECs, investigators, forensic scientists, and other MDI collaborators identified by the MDI-Data-WG. It also identifies high-priority needs that, if fulfilled, will build a foundation toward implementing best practices and standards, promoting improved data collection and surveillance, and supporting data exchange for MDI.
The information collected in this document will impact MDI and forensic science communities in the United States by (1) defining, updating, and establishing the most frequently exchanged data elements that are necessary components of a comprehensive and modernized data exchange in MDI; (2) laying the framework for how drugs are named and how these names are communicated to others; and (3) documenting workflow processes, data exchange needs and processes, data standardization methods, and common language for the MDI systems and its stakeholders.

Medicolegal Death Investigation Frequently Used Data Elements
This graphic shows the final list of data elements that should be collected for every case. This graphic also links these frequently used elements to overarching categories of death investigation and indicates how these elements are integrated into the death investigation process. Italicized items are examples of information that could be provided during an investigation, and standard information is represented in normal text. This graphic can be downloaded and used in agency training to ensure all data are collected. Additionally, the graphic can be used to develop checklists for death investigators, develop programming requirements for data developers to code MDI information, or assist with standardization and consistency among data exchange as part of other resources.
Drug Taxonomy: Framework for Subclassification and Naming of Novel Psychoactive Substances
This framework tool can assist forensic scientists seeking to better understand how drugs are classified by structural components. It is broken down by NPS classes (e.g., opioids) and then further subdivided by subclassifications of each NPS class (e.g., fentanyl analogs). This framework provides potential names for a substance, a figure with a drug structure from the subclass (with core components highlighted), and an example substance that fits within this subclassification. Users of this framework can easily follow this layout to understand how NPS are subclassified and how those drug molecules could be named. The framework was created to be a standalone poster to use as a reference. This alleviates scientists of the need to check multiple sources and allows for quicker association with naming convention and nomenclature. Although this framework tool helps users understand the drug-naming process, it does not provide a means to predict and name future unknown substances by simply following this subclassification scheme and framework.
Ideal State Required for Successful Medicolegal Death Investigation Data Exchange Across Data Exchange Entities
This graphic shows the ideal state of medicolegal death investigation data exchange among data entities (i.e., data users and data producers). Data users and data producers are all data entities located in the outermost ring. Each data entity segment indicates specifically named data types or data exchanged systems within it. Arrows in the background indicate the primary (larger arrow), secondary (smaller arrow) or equivalent (equal arrow size) direction of data workflow either coming from the medicolegal death investigation system (i.e., medical examiner and coroner offices within the United States) or being provided to the medicolegal death investigation system indicated by the innermost ring. A middle ring indicates the "System of data programmers and technology developers" that play a professional role by assisting with modernization and digitization of data for the medicolegal death investigation system.
