A new study shows there is a spike in blood donations after a tragedy – like the 2017 Las Vegas mass shooting. A new study co-authored by University of Nebraska – Omaha Assistant professor Justin Nix with the School of Criminology and Criminal Justice shows that a significant amount of blood donated immediately after a mass causality is not used.

Nix says they learned that 500 units of blood were used the day of the shooting. In that same time frame, donors gave nearly 800 units.
Nix has some recommendations on how to respond to those types of incidents.

Nix says there has to be a better way to manage the supply of donations so resources don’t go unused.
