This paper presents the protocol for the NUTRIFRAG Study, a prospective, observational, multicentre investigation. The study will collect data on nutritional status, malnutrition risk, dysphagia, functionality, cognition, comorbidity, and other variables at admission and follow-up until discharge. Planned analyses include calculating incidence and prevalence of these conditions, using logistic and Cox regression models to study associations with risk factors, and evaluating patient satisfaction with food services. Key strengths include the large sample size and multicentre design. Limitations acknowledged in the protocol include potential variability in data collection across centres and the complexity of using multiple measurement instruments. The study aims to provide data to improve clinical protocols and highlight the role of multidisciplinary teams in managing malnutrition and dysphagia during hospitalization.
