Injury & Violence Prevention


The Miami-Dade County Injury Surveillance System (MDCISS) was initiated in 2004 to obtain accurate and timely information on the incidence and determinants of fatal and nonfatal injuries that occur to Miami-Dade residents. The objective of the MDCISS is to provide data that can be used to initiate or assist injury prevention programs and help measure their effectiveness. The MDCISS is a collaborative effort between the Miami-Dade County Health Department, the Injury Free Coalition for Kids-Miami, the University of Miami and Jackson Health Systems. It has been supported, in part, through funding from The Children’s Trust and the Health Foundation of South Florida.

Further, for every injury-related death to a county resident in 2012, there were an additional 13 nonfatal hospitalizations and 158 emergency department visits due to an injury.
