Characterization and monitoring of nutritional risk and nutritional status in oncological patients admitted to an oncological surgery unit: A longitudinal study

Background and aims: malnutrition is a common phenomenon in people with cancer and can occur at all stages of the disease trajectory. Prevention, early identification of patients at risk of malnutrition, nutritional diagnosis, and personalized intervention, monitoring and follow-up are essential measures to minimize the occurrence of malnutrition and its consequences. This study aims to evaluate if current institutional practices regarding nutritional intervention guarantees nutritional/dietary care for cancer patients. Methods: adescriptive, analytical and longitudinal study was carried out, lasting five months, in a hos-pital inpatient surgical oncology unit. All patients admitted to the unit in the period between 1 March and 31 July 2022, who underwent nutritional screening at the time of admission to the service, were included. During hospitalization, they were subjected to periodic assessments of weight, body mass index and nutritional screening every 7 days until discharge.Results: a total of 659 patients were admitted to the inpatient unit. The highest prevalence of malnutrition was observed in Head and Neck (37.6%), Genitourinary (30.8%) and Digestive (27.7%) cancers. Weight loss was especially significant in digestive, skin and sarcoma cancers, as well as genitourinary cancers, but not in breast cancer patients. During the hospitalization period, 14.0% of the hospitalized patients received nutrition-related nursing intervention, and 21.5% were referred for clinical dietetic intervention (by a registered dietitian).Conclusion: this work reinforces the high prevalence of malnutrition in oncological patients and the need to systematically track cancer patients throughout their disease/treatment trajectory, from admission to the hospital, to the day of admission to inpatient unit, and subsequent follow-up. We also propose expedited referrals to different specialized centres in nutritional support for cancer patients from the first day of hospitalization. Assessment of patients should always be accompanied by active referral capacity to a specialized and duly trained nutritional care team that is quick, proactive, and responsive.& COPY; 2023 The Authors.
