The consensus statement is based on the Evidence Analysis Center's malnutrition in older adults systematic reviews that evaluated nutrition assessment and nutrition interventions, and the expertise of content experts. Strategies to improve access to nutrition care within a regulatory and systemic context are presented. The consensus statement identifies key barriers to nutrition care, including fragmented health care systems, insufficient research, and limited reimbursement for nutrition services. Several strategies are proposed, including policies to ensure comprehensive screening and referral, evidence-based individualized nutrition care, expanded reimbursement for nutrition services, adequate RDN staffing, increased research, and coordination with available community nutrition programs.
