EHR eliminates the need to track down a patient's previous paper medical records and assists in ensuring that the patient's medical data is accurate, legible and up-to-date. Handwritten paper medical records may be poorly legible, which can contribute to medical errors.
Electronic health records help with the standardization of forms, terminology and data input.
The increased transparency, portability and accessibility acquired by the adoption of electronic medical records may increase the ease with which they can be accessed by healthcare professionals.
EHR systems accurately capture the state of a patient across time and provide insight into possible trends and long term changes in a patient's health history.
Population-based studies of medical records may also be facilitated by the widespread adoption of EHRs and EMRs.
Promoting patient participation can encourage healthier lifestyles and more frequent use of preventative care.
An EMR (Electronic Medical Record) is a single practice's digital version of a patient's chart and is a narrower view of a patient's medical history, while an EHR is a more comprehensive report of the patient's overall and are designed to be shared with other providers, so authorized users may instantly access a patient's medical records.
While an EMR is mainly used by providers for diagnosis and treatment and are not designed to be shared outside the individual practice, EHRs allow a patient's medical information to move with them to specialists, labs, imaging facilities, emergency rooms and pharmacies, as well as across state lines.
