Which term denotes the latest version of OASIS guidance?

• A. Documentation Principles
• B. Exam Information
• C. OASIS-E1
• D. Functional Impairment

Answer: (C)

OASIS-E1 is the label used for the most current set of OASIS guidance. In this system, updates to the guidance are released as new versions, with the “E1” suffix signaling the latest iteration of instructions, data elements, and scoring rules that clinicians follow when completing assessments. The other options don’t represent the versioning of OASIS guidance: general Documentation Principles refers to broad documentation standards, Exam Information would cover the certification process itself, and Functional Impairment is a clinical concept/area, not a version name for OASIS. So the term denoting the latest guidance is OASIS-E1.
