EBM can be used for a number of reasons. It helps to ensure that the medical services provided are not based on outdated information, or biased personal opinions. Due to the focus it places on data driven decision making, this can help reduce medical error risks. In the end, it improves both patient safety and overall care quality.
EBM has positive effects on public health. By providing clinicians with access to current research findings they are better equipped to identify and treat potential diseases before they become more widespread—thus promoting better long-term outcomes for entire populations. The data collected in studies can be used to better understand individual and collective needs for health later on, which will help us inform future policies aimed at improving overall healthcare.
