National Implementation of an Artificial Intelligence-Based Virtual Dietitian for Patients With Cancer.

PURPOSE: Nutritional status is an established driver of cancer outcomes, but there is an insufficient workforce of registered dietitians to meet patient needs for nutritional counseling. Artificial intelligence (AI) and machine learning (ML) afford the opportunity to expand access to guideline-based nutritional support. METHODS: An AI-based nutrition assistant called Ina was developed on the basis of a learning data set of >100,000 expert-curated interventions, peer-reviewed literature, and clinical guidelines, and provides a conversational text message-based patient interface to guide dietary habits and answer questions. Ina was implemented nationally in partnership with 25 advocacy organizations. Data on demographics, patient-reported outcomes, and utilization were systematically collected. RESULTS: Between July 2019 and August 2023, 3,310 users from all 50 states registered to use Ina. Users were 73% female; median age was 57 (range, 18-91) years; most common cancer types were genitourinary (22%), breast (21%), gynecologic (19%), GI (14%), and lung (12%). Users were medically complex, with 50% reporting Stage III to IV disease, 37% with metastases, and 50% with 2+ chronic conditions. Nutritional challenges were highly prevalent: 58% had overweight/obese BMIs, 83% reported barriers to good nutrition, and 42% had food allergies/intolerances. Levels of engagement were high: 68% texted questions to Ina; 79% completed surveys; median user retention was 8.8 months; 94% were satisfied with the platform; and 98% found the guidance helpful. In an evaluation of outcomes, 84% used the advice to guide diet; 47% used recommended recipes, 82% felt the program improved quality of life (QoL), and 88% reported improved symptom management. CONCLUSION: Implementation of an evidence-based AI virtual dietitian is feasible and is reported by patients to be beneficial on diet, QoL, and symptom management. Ongoing evaluations are assessing impact on other outcomes.

Malnutrition Screening: An Interprofessional Approach in Outpatient Oncology.

BACKGROUND: Malnutrition is highly prevalent in the oncology population and is associated with poor treatment outcomes. OBJECTIVES: This study aimed to implement a malnutrition screening process using a validated tool in three outpatient cancer centers. METHODS: Nursing and nutrition department leaders collaborated to establish malnutrition screening. The Malnutrition Screening Tool (MST) was embedded in the electronic health record. Based on the MST, a score of 2 or greater is considered at risk for malnutrition. Nurses were educated on screening all patients completing their first cycle of infusion chemotherapy. Data were collected for six months. FINDINGS: Interprofessional collaboration established a process to implement malnutrition screening. Twenty-eight percent of patients with cancer were at risk for malnutrition. Fifty-three percent were at risk for malnutrition based on MST scores of 2. Compliance with the MST at first infusion visit was 30%-81% across the three cancer centers.
