The study at hand involved 183 patients in Greece.
In multivariate analyses, hospital LOS [length of stay] decreased by 0.3 d for each unit increase of MedDiet score (P < 0.0001), 2.1 d for each 1 g/dL increase of albumin (P = 0.001) and increased 0.1 d for each day of previous admissions (P < 0.0001). Extended hospitalization (P < 0.0001) and its interaction with MedDiet score (P = 0.01) remained the significantly associated variables for financial cost. Mortality risk increased 3% per each year increase of age (hazard ratio [HR], 1.03; P = 0.02) and 6% for each previous admission (HR, 1.06; P = 0.04); whereas it decreased 13% per each unit increase of MedDiet score (HR, 0.87; P < 0.0001).
Adoption of the MedDiet decreases duration of admission and long-term mortality in hospitalized patients >65 y of age, with parallel reduction of relevant financial costs.
