Mediterranean Diet Decreased Hospital Length of Stay, Reduced Mortality, and Cut Medical Costs of Elderly Patients

Somewhere on on the Mediterranean Sea

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.
