Association between fluid balance trajectories and prognosis in older patients with malnutrition: a group-based trajectory model analysis (opens in new tab)

BackgroundFluid balance plays a crucial role in the management of older patients with malnutrition; however, the impact of different fluid balance trajectories on prognosis has not been fully elucidated. This study aimed to evaluate the association between fluid balance trajectories and the risk of 30-day mortality in older patients with malnutrition.MethodsThis study was conducted using data from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database.
