Beyond the E Code Matrix: Choosing the Red Pill

Wednesday, September 13, 2017 at 8:00 AM–9:15 AM MDT
Conference Room 2
Learning Objectives

In this session, participants will: 

  1. Objective 1: Understand alternative paradigms for examining hospital discharge data, with an increased focus on behaviors.
  2. Objective 2: Articulate the benefit of examining non-injurious risk factors.
  3. Objective 3: Know how some of the CSTE Surveillance Indicators for Substance Abuse and Mental Health are being incorporated into Minnesota's online query system.
Statement of Purpose

The External Cause (E code) Matrix has been the standard paradigm for reporting on injury and violence using hospital discharge data. The Minnesota Department of Health (MDH) built an interactive query system for hospital discharge data known as MIDAS (Minnesota Injury Data Access System); this has been a very useful tool for providing injury/violence data and information to end users.

However, reporting on injury and violence has become more nuanced, including aspects such as suicidal ideation, sexual assault examinations without injury, opioid poisonings, etc. There is increased need for alternative and enhanced data queries.


The MDH has expanded the modules within the MIDAS data query system beyond the standard E code matrix categories to now include MIDAS-Violence, MIDAS-CODES, and poisoning subgroups. In development are MIDAS-Dashboard and MIDAS-Behaviors. An important aspect in the development of these modules has been the determination of case definitions and classifications.


The MIDAS modules are coming online at, as are the case definitions and classifications.

Conclusions & Significance to the Field

This new and innovative approach to reporting on injury/violence goes beyond the existing reporting paradigm of the E Code Matrix. Including non-injurious violence and behaviors helps injury prevention professionals and their community partners to assess prevention efforts further “upstream”.
