EHR or Electronic Health Records, are computerized versions of patients' paper health charts. They make information available instantly, "whenever and wherever it is needed". EHRs can:

• Contain information about a patient's medical history, diagnoses, medications, immunization dates, allergies, radiology images, and lab and test results

• Offer access to evidence-based tools that providers can use in making decisions about a patient's care

• Automate and streamline providers' workflow

• Increase organization and accuracy of patient information

• Support key market changes in payer requirements and consumer expectations

A single EHR can bring together information from current and past doctors, emergency facilities, school and workplace clinics, pharmacies, laboratories, and medical imaging facilities.
