Electronic Medical Record (EMR) encompasses the medical history – tests, diagnoses, treatments and other elements – of a single patient specific to a particular facility. The record is owned by the provider. EMRs may be used to achieve a more efficient exchange of information within the facility and to guide clinical decision-making. Likewise, an EMR system describes the local provider’s computerized environment that makes these records possible.
Electronic Health Record (EHR) ideally includes a patient’s complete medical history, spanning multiple providers and geographies. A comprehensive EHR requires compilation of data from various EMRs. In the case of personal health records (PHR) such as those provided by Microsoft HealthVault® or MyHealthRecord®, and Google Health®, the patient owns the record, but most EHRs are owned by a facility, insurance company or insurance consortium. The EHR is the type of record proposed to reside on a shared National Health Information Network.
Legal Health Record (LHR) is similar to an EMR in that it comprises a patient’s information from a single care provider, but carries with it a more binding and unalterable structure. According to the American Health Information Management Association (AHIMA), the LHR serves as the hospital’s permanent business record and would be released upon request if the appropriate patient consent was on file.
