What describes accuracy and completeness of collected OASIS data?

• A. Data Quality
• B. Medicare CoPs
• C. ADL/IADL Items
• D. Item M1033

Answer: (A)

Data quality describes how accurate and complete the information collected on OASIS is. It covers the correctness of the recorded patient status and services (accuracy) and whether all required items are filled in without gaps (completeness). High data quality is essential for valid clinical decisions, proper care planning, and appropriate reimbursement and quality reporting. The other options refer to regulatory requirements (Medicare CoPs), specific types of items (ADL/IADL items), or a single data item (Item M1033), not the overall characteristic of the data.
