Description I: The system must have a mechanism to handle versions and succession of Record Entries (such as a preliminary and final laboratory reports, amended or corrected documents). Versioning and succession management is based on Record Entry content, and/or status change over time. A version may be one of: 1) A completed and attested Record Entry; 2) A Record Entry completed and attested which has been modified one or more times; 3) A Record Entry that has been viewed for clinical decision-making purposes by an individual other than the author; 4) A Record Entry that has been captured in an incomplete state per organization business rules and updated over time (i.e., a preliminary laboratory test); 5) A Record Entry that electively, according to the author, must be preserved in the current state at a given point in time (i.e., History and Physical). Certain types of Record Entries are typically handled in versions, for example: - Laboratory results (preliminary and final) - Dictated reports - Work ups (over course of days) The prior version of Record Entries should be retained for the legally prescribed timeframe as defined by scope of practice, organizational policy, and jurisdictional law.
