Z-Score Burden Metric: A Method for Assessing Burden of Injury and Disease

Passcode:#x$8F!DN

Description: This presentation will demonstrate a new method of burden assessment for use in identifying communities within a population that are in need of prevention and intervention resources. The Z-Score Burden Metric, demonstrated with firearm fatality data, uses z-score standardization of incidence data to describe community burden of injury in a way that facilitates comparisons between communities with different age distributions and enables identification of subgroup trends. This method addresses some shortcomings of traditional measures, like unadjusted and age-adjusted rates, and can be used for any injury or disease outcome to prioritize the allocation of resources to communities suffering high burdens of injury and disease.

Objectives:

  1. Discuss the justification for an approach to quantifying burden specifically designed to facilitate policy and implementation goals
  2. Demonstrate the Z-Score Burden Metric using firearm fatality data
  3. Describe how the method can be adapted to suit the needs of different programs’ priorities

Presenter: Dr. Catherine (Katie) Wolff, PhD, is an injury epidemiologist who recently completed her doctoral work in firearm-related injury and a postdoctoral fellowship in occupational injury at the University of North Carolina at Chapel Hill (UNC). Catherine is also a medical student at Duke University and plans to specialize in emergency medicine.
