The document discusses the electronic health record (EHR) and its benefits. An EHR centralizes a patient's medical records including diagnostic tests and treatment history and allows any healthcare provider secure access to this information. This ensures providers have complete information to aid in diagnosis and treatment. EHRs help reduce medical errors, streamline care, and empower patients by allowing some to access and contribute to their own records online. While privacy is a concern, laws aim to protect sensitive health information and only grant access to authorized individuals.
