Final answer:
EHR systems are designed to decrease medical errors by improving the accuracy and sharing of patient data, thus reducing unnecessary testing and enhancing healthcare coordination.
Step-by-step explanation:
EHR systems, or electronic health records systems, are intended to decrease medical errors. These systems were part of the regulatory changes introduced by the Affordable Care Act (ACA) to control increasing healthcare costs. The ACA mandated that healthcare providers switch to electronic medical records (EMRs), which not only aim to reduce administrative costs but also bolster the sharing of digital records among health providers. This enhances the accuracy of patient data, reduces duplication of testing, and improves overall health care coordination, contributing to a decline in errors.
