Final answer:
The development and management of the OASIS data set is handled by the Centers for Medicare & Medicaid Services (CMS), not the Community Health Accreditation Program (CHAP), making the statement false.
Step-by-step explanation:
The statement that the Community Health Accreditation Program (CHAP) is responsible for the development of the OASIS data set and manages data collection using OASIS for home care providers nationwide is False.
The development of the OASIS (Outcome and Assessment Information Set) is actually overseen by the Centers for Medicare & Medicaid Services (CMS), which is a federal agency within the United States Department of Health and Human Services (HHS). The OASIS data set is designed for use in home health agencies to ensure comprehensive assessment for adult patients receiving home-based care and to inform quality improvement efforts.
