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.
