NCCMT - URE - What’s the Risk? Understanding Absolute and Relative Risk Reduction

Video created: May 10, 2016 Studies on the effectiveness of public health interventions can present the results in different ways. Knowing how to interpret these results will not only help you understand how effective an intervention is, but also how meaningful it will be to your population. In this eight-minute video, we look at how three statistics – baseline risk, relative risk and absolute risk – are connected and how using them together can help you make better informed public health decisions. The video uses the example of injury prevention in a senior population to demonstrate how absolute and relative risk reductions are calculated. Greater understanding of these statistics will help you apply evidence in your practice, contributing to enhanced public health outcomes.
