The MCS assesses the percentage of hospitalizations for adults 65 years and older (if reporting data from 2024 and 2025) or all adults 18 years and older (for reporting data in 2026 or later), with a length of stay of at least 24 hours that have received optimal malnutrition care during the current inpatient hospitalizations.
The MCS follows evidence-based guidance to support malnutrition care.
Development of the MCS
In the United States, quality measures help patients choose high-performing clinicians and enable healthcare providers to assess and improve care. The Malnutrition Care Score (MCS) - formerly the Global Malnutrition Composite Score (GMCS)—is the first nutrition-focused electronic clinical quality measure (eCQM) included in the Centers for Medicare and Medicaid's (CMS) Hospital Inpatient Quality Reporting (IQR) Program under the FY 2023 Inpatient Prospective Payment System (IPPS) Final Rule.
Developed and stewarded by the Academy of Nutrition and Dietetics, the MCS was endorsed by the National Quality Forum (NQF) Consensus Standards Approval Committee (CSAC) for 2021-2024. In spring 2024, the Partnership for Quality Measurement (PQM) Endorsement and Maintenance (E&M) Committee also endorsed updated specifications that include the expansion to adults aged 18 and older (CBE ID 3592e).
