What does injury surveillance help to inform within public health?

Injury surveillance plays a critical role in public health by systematically collecting and analyzing data on injuries to identify trends and risk factors. This information is essential for informing policy-making decisions. By understanding the prevalence and causes of injuries in a population, public health officials can develop targeted interventions and allocate resources effectively. This data-driven approach helps shape laws, regulations, and programs aimed at reducing injury rates and improving safety in communities.

The other options, while they may be influenced by injury data, don't directly reflect the primary function of injury surveillance. Community outreach programs might be developed based on findings, but they stem from the policy decisions informed by surveillance data. Medical service supply and fitness regulations are external considerations that can be impacted by broader health policies, but they are not the direct focus of injury surveillance.
