Assessing Impact of Nutrition Care by Registered Dietitian Nutritionists on Patient Medical and Treatment Outcomes in Outpatient Cancer Clinics: A Cohort Feasibility Study. Nutr Cancer 2023; 75:923-936. [PMID: 36691979 PMCID: PMC10029747 DOI: 10.1080/01635581.2023.2170431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 01/16/2023] [Indexed: 01/25/2023]
Abstract
More information is needed about the impact of outpatient nutrition care from a registered dietitian nutritionist (RDN) on patient outcomes. This study aimed to assess the feasibility of a cohort study design to evaluate impact of RDN nutrition care on patient outcomes, describe clinic malnutrition screening practices, and estimate statistical parameters for a larger study. Seventy-seven patients with lung, esophageal, colon, rectal, or pancreatic cancer from six facilities were included (41 received RDN care and 36 did not). RDN nutrition care was prospectively documented for six months and documented emergency room visits, unplanned hospitalizations and treatment changes were retrospectively abstracted from medical records. Most facilities used the Malnutrition Screening Tool (MST) to determine malnutrition risk. Patients receiving RDN care had, on average, five, half hour visits and had more severe disease and higher initial malnutrition risk, although this varied across sites. Documented medical and treatment outcomes were relatively rare and similar between groups. Estimated sample size requirements varied from 113 to 5856, depending on tumor type and outcome, and intracluster correlation coefficients (ICCs) ranged from 0 to 0.47. Overall, the methods used in this study are feasible but an interventional or implementation design might be advantageous for a larger study.

Abstract
Research is essential to further advance our understanding of the role of nutrition and dietetics in maintenance and improvement of health. Research is also essential for nutrition and dietetics professionals to create and provide evidence-based interventions, including medical nutrition therapy (MNT) provided by registered dietitian nutritionists (RDNs). Given this critical role of research, the Academy of Nutrition and Dietetics (Academy) has a variety of resources to assist its members in accessing, understanding, participating in, conducting, and disseminating nutrition research. These resources are comprehensive and include opportunities to participate in research (e.g., Nutrition Research Network (NRN) and Data Science Center (DSC)), tools to aggregate practice data (Nutrition Care Process and Terminology (NCPT) and the Academy of Nutrition and Dietetics Informatics Infrastructure (ANDHII)), funding opportunities to support primary research (e.g., Academy Foundation), resources to understand the latest research informing evidence-based practice (EBP) (e.g., Evidence Analysis Center (EAC)), and avenues for sharing research findings (e.g., Food and Nutrition Conference and Expo (FNCE)). The aim of this paper is to encourage members to get involved in research by describing Academy-based research resources and opportunities to contribute to nutrition and dietetics research, as well as describe specific examples of research conducted at Academy. The information presented can serve as a framework to guide members in engaging in research through the Academy.
