The University of Pennsylvania School of Nursing (Penn Nursing) has been awarded a $3.2 million, 5-year grant from the National Institute of Nursing Research (NINR) to scale out an evidence-based secure firearm storage intervention at Children’s Hospital of Philadelphia (CHOP). Firearms are now the leading cause of death for U.S. children and teens, driving the largest spike in children’s mortality in more than 50 years. The study aims to keep children safer from firearm injury and mortality by promoting secure firearm storage.
