What the evidence says
Violence and injury observatories are information centers that create surveillance systems for violence reduction by collating data from various sources, analyzing patterns, and sharing findings with relevant agencies. Evidence suggests that their implementation has led to significant reductions in violence-related outcomes, including a reported 82% decrease on average. These observatories rely on collaboration between agencies for effective implementation and data sharing, but further research is needed to understand the mechanisms behind their success.
How it works
These observatories reduce violence by facilitating data collection and promoting cooperation between various agencies involved in violence prevention, leading to better-informed interventions.
Implementation
Implementation requires collaboration among governmental and non-governmental agencies responsible for violence-related data, promoting a public health approach rather than a purely clinical one.
