What is an EHR (Electronic Health Record)?
An electronic health record (EHR) is the digital record of a client's health information - demographics, diagnoses, assessments, treatment plans, session documentation, and authorizations - kept by a provider and governed by HIPAA.
In ABA the EHR holds the client's whole clinical story: intake and diagnosis, the initial assessment and treatment plan, session notes and supervision records, progress reports, and the authorizations covering the services being delivered.
Because it contains protected health information, it carries requirements a general business system doesn't - access controls, audit trails, secure storage and transmission, and a business associate agreement with any vendor that handles the data.
For most practices the EHR isn't a separate product but the clinical half of their practice management platform, so what a technician documents during a session lands in the same record that scheduling, reporting, and billing all draw from.
