Electronic health records (EHRs) contain a patient's digital medical history that can be shared securely across different healthcare providers and settings. EHRs allow doctors to easily access patient information, share it with specialists, and provide patients with access to their own health data. This empowers patients by reducing paperwork and unnecessary tests, improving care coordination, and enabling better health management through reminders and test result access. However, EHRs must comply with privacy laws like HIPAA to protect the security of personal health information.
