MDS 3.0 for Nursing Facilities in Maine

The MDS is a powerful tool for implementing standardized assessment and for facilitating care management in nursing homes (NHs) and non-critical access hospital swing beds (SBs). Its content has implications for residents, families, providers, researchers, and policymakers...

MDS 3.0 has been designed to improve the reliability, accuracy, and usefulness of the MDS, to include the resident in the assessment process, and to use standard protocols used in other settings. These improvements have profound implications for NH and SB care and public policy. Enhanced accuracy supports the primary legislative intent that MDS be a tool to improve clinical assessment and supports the credibility of programs that rely on MDS. Excerpted from CMS website
