Objectives: The objective was to investigate if differences in weight outcomes existed for oncology patients seeing Registered Dietitian Nutritionists (RDNs) between pre-pandemic versus COVID-19 pandemic-era care.

Methods: A retrospective chart review analyzed patients who received nutrition interventions with RDNs over 12 weeks at a midwestern outpatient cancer center. Data were collected from patient care encounters in 2019 (Cohort 1, pre-pandemic) and 2021 (Cohort 2, pandemic). Weight maintenance was defined as within 7.5% of baseline weight, based off malnutrition criteria of weight loss over 3 months. Weight, malnutrition, and nutrition support were analyzed to identify comparability of cohorts. Independent samples t-tests and Chi Square tests were used, with statistical significance set at p < 0.05.

Results: The final analysis included 50 participants in Cohort 1 and 46 in Cohort 2. In total, the majority of patients were White (85%), with a mean age of 62 years. No statistically significant differences were found between Cohort 1 and Cohort 2. While weight loss prior to seeing an RDN was high in both groups, it was not significantly different between groups (Cohort 1: -9.92% vs Cohort 2: –10.69%, p=0.560). In both cohorts, 70% of patients either maintained or gained weight during the 12 weeks (p = 0.983). Additionally, Cohorts 1 and 2 maintained similar weight amounts over 12 weeks (-3.62 kg ± 5.52 kg, versus -3.12 kg ± 6.65 kg; p = 0.688). Similar proportions of patients were malnourished (p = 0.295) and used nutrition support (p = 0.285).

Conclusions: Outpatient RDN interventions effectively supported oncology patients’ weight and nutritional status during both pre-pandemic care and pandemic-era care. Despite considerable weight loss prior to seeing an RDN, further weight loss was attenuated in both groups. High-level nutrition care persisted during the COVID-19 pandemic, while facing many healthcare challenges.
