Time trend prevalence of artificial nutrition counselling in a university hospital

Objectives: The negative effects of malnutrition on the prognosis of hospitalized patients are well documented; however, less known is the awareness and knowledge of health care professionals about this complication. The aim of this study was to evaluate the trend of the requests for nutritional consultation in years and the prescription of artificial nutrition (AN), for adult patients at a university hospital in southern Italy in the years 2004, 2008, 2012, and 2016 to assess the progress of medical teams concerning awareness of hospital malnutrition.

Methods: This was a retrospective study that evaluated the time trend of nutritional consultation requests and related prescription of AN, for adult patients at a university hospital in southern Italy in the years 2004, 2008, 2012, and 2016. Of 112 233 inpatients, 2505 received a nutritional consultation with the prescription of AN.

Results: The number of patients on AN increased from 507 of 33 240 (1.52%) in 2004 to 730 of 29 195 (2.5%) in 2008 (P < 0.001), remaining almost stable in 2012 and 2016. The request for AN was quite equally distributed between surgical (51.5%) and medical wards (48.5%), with a prevalence among patients with oncologic diseases (806 patients [65.6%]). As for nononcologic diseases, 20.4% involved the gastrointestinal tract and 6.3% the nervous system. Throughout the 12 y of observation, parenteral nutrition was the main prescribed support (59.8%) followed by oral nutritional supplements (26.1%) and enteral nutrition (9.3%). Mean nutritional intervention duration was 11 d (±10.8 d).

Conclusions: The request of AN for hospitalized patients increased over time, probably owing to improved medical consciousness of the potential risks for malnutrition and the availability of a specialized clinical nutrition team.
