Electronic health records (EHR) digitally store patient health information including medical history, treatment, allergies, medications, and lab results. EHRs allow for the management of health data using modern techniques and provide clinicians tools for clinical decision support. While EHRs have benefits, issues include integrating historical records, ensuring data security and integrity, and start-up and maintenance costs. EHRs do not replace in-person communication between providers and patients, which remains important.
