GLOBAL MALNUTRITION COMPOSITE SCORE

The Centers for Medicare and Medicaid Services (CMS) is an insurer, but also collects and analyzes data to produce reports utilizing quality improvement and quality measurement data to improve outcomes while reducing burden on clinicians and providers.

Under the CMS umbrella of programs lies the Inpatient Quality Reporting (IQR) Program, a Pay-for-Reporting program that requires hospitals to submit data on quality and safety measures focused on reducing hospital-related complications and mortality and offering high-quality care. The results are publicly reported on the Care Compare website. 

Electronic clinical quality measures (eCQMs) are one of many programs under the IQR system. These measures use data electronically extracted directly from electronic health records (EHR) and/or health information technology (HIT) systems to measure the quality of health care provided. The facility submitting eCQM measures does so directly from the EHR or IT systems. 

The GMCS, is stewarded and currently developed, by the Academy of Nutrition and Dietetics. It was approved as an eCQM and is 1 of 9 eCQMs available measures for reporting in 2024 and 2025. Currently, Eligible Hospitals and Critical Access Hospitals must report on 6 electronic clinical quality measures for each reporting period-three mandatory and three self-selected. The GMCS is currently available as a self-selected measure. 

When preparing to implement the GMCS, it is important to keep in mind the following terms that indicate the reporting timeline (as seen in the figure below). The Reporting Period is the calendar year that the data will be collected. The data collected will then be submitted the following year, during the Submission Period. 

Ultimately, the data reported and submitted will directly be linked to the Payment Period Fiscal year that corresponds to the year after the Submission Period.

The Global Malnutrition Composite Score, or GMCS, is the first nutrition-focused electronic clinical quality measure (eCQM) to be included in the Centers for Medicare and Medicaid (CMS) Hospital Inpatient Quality Reporting (IQR) Program in the FY 2023 Inpatient Prospective Payment System (IPPS) Final Rule published in October 2022. It was also endorsed by unanimous vote of the National Quality Forum (NQF) Consensus Standards Approval Committee (CSAC) in 2021. The measure is at this time, in the process of being re-endorsed by the Partnership for Quality Measurement’s (PQM) Endorsement and Maintenance (E&M) Committee. 

The GMCS assesses the percentage of hospitalizations for adults 65 years and older with a length of stay of at least 24 hours who received optimal malnutrition care during the current inpatient hospitalizations, emphasizing that care performed corresponds to the patient's level of malnutrition risk and severity. Expansion of the measure population age from 65 to 18 years of age is expected to be available for Reporting Period Calendar Year 2026. 

The GMCS follows evidence-based guidance to support malnutrition care, as shown below.

Malnutrition is defined as the inadequate intake of nutrients or energy, over time. It can have many root causes, including reduced oral intake, increased energy and nutrient needs, malabsorption, and/or social determinants of health. A hospitalized patient with malnutrition can place a strain on resources, and negatively affect the quality outcomes, as shown in the figure below.

Some of the benefits observed by facilities that implemented malnutrition care processes include a reduction of 27% of 30-day readmission rates4, $4.8 million in cost savings generated by a 4-hospital system5, and 24% relative reduction in readmission risk for malnourished patients with a nutrition care plan7. 

Clinical guidelines for addressing malnutrition in acute care settings establish that a patient should first be screened for malnutrition risk, those at risk should be further assessed, and if found to have malnutrition by screening and assessment, then a nutrition support plan should be established3. Furthermore, an effective malnutrition care process benefits from interdisciplinary collaboration. This type of care offers an opportunity to develop a comprehensive and individualized assessment and treatment plan, and thus supporting accurate diagnosis and effective care. The following graphic shows the key roles different profession in a hospital can offer to help achieve successful implementation of the GMCS.

The GMCS was built following the recommended workflow of evidence-based malnutrition care. It also encourages interdisciplinary care discussions and involvement during the implementation phase and the clinical care itself. Although the GMCS was developed for the acute care setting, its proven framework can be adapted to any practice area to improve patient outcomes and quality of care. 

Benefits of Implementing the GMCS: 

• Providing care measured through the GMCS supports hospitals’ strategic plans to address social determinants of health and equity.
• All four components are often already established to a degree in all acute care facilities. 
• Addresses several clinical areas or quality indicators simultaneously, including: 
  • Nutrition Screening - The Joint Commission 
  • Social Determinants of Health and Food Insecurity - The Joint Commission, CMS, 2023 Healthcare Effectiveness Data and Information Set’s (HEDIS) Social Need Screening and Intervention Measure 
  • Health Equity Advancement - identified by CMS as a priority eCQM 
  • Rural Health Improvement- identified by NQF as a key measure** 
• Combines several quality measures into one single composite score, giving a more comprehensive picture of clinical care than a single measure.
• Promotes multidisciplinary engagement, supporting communication and employee satisfaction efforts.

• Malnutrition Quality Improvement Initiative (MQii): a project of the Academy of Nutrition and Dietetics, Avalere Health, and other stakeholders who collaborate to provide guidance and expertise for clinical malnutrition. The primary goal is to advance evidence-based, high-quality, patient-driven care for hospitalized older adults who are malnourished or at-risk for malnutrition.
  • MQii Toolkit: supports the implementation of malnutrition care best practices.
  • MQii Learning Collaborative, a community of clinicians committed to improving delivery of malnutrition care in hospitals and health systems across the US.

*Reporting Period is the period where data is collected. Submission Period is when data collected the prior year is submitted, usually during the Spring Quarter. Payment Period is the fiscal year the payment could potentially be affected if criteria for reporting is met or not met.
