Introduction:

disease-related malnutrition (DRM) affects more than 30 million people in Europe, representing about 170 billion euros each year. Despite the growing consensus for the diagnosis of DRM, it is still necessary to implement multidisciplinary and coordinated protocols for a comprehensive approach to DRM in hospitals.

Objetive:

to study the proportion of patients affected by DRM upon admission, as well as the duration and the cost of their stay in a general hospital.

Methods:

an observational cross-sectional study with a sample size of 203 subjects. From June to December 2018, a nutritional screening was carried out according to the Nutritional Risk Screening 2002 (NRS-2002); diagnoses were made according to the Global Leadership Initiative on Malnutrition (GLIM) criteria, length of stay was recorded, and the cost of stay was estimated for all patients admitted to Internal Medicine who met the selection criteria.

Results:

the proportion of people at risk of DRM was 28 % (57/203; 95 % CI: 22 % to 34 %). The proportion of patients diagnosed with DRM was 19 % (36/192; 95 % CI: 13 % to 24 %). Patients classified with risk or diagnosis of DRM upon admission had a longer stay than those with normal nutrition by 3 days (p < 0.01), and a higher cost by €1,803.66 (p < 0.01).

Conclusions:

a comprehensive, multidisciplinary approach to DRM coordinated from Primary Care to hospitals is necessary, especially in women aged ≥ 70 years with pulmonary disease.
