Association between nutritional risk based on the NRS-2002 test and hospital morbidity and mortality
2012
Objective: To analyse the relationship between the
presence of malnutrition (MN), as measured by the NRS-
2002 nutritional evaluation, and the rate of morbidity and
mortality.
Design: Cross-sectional study.
Setting: Patients admitted to Mateu Orfila Hospital,
the regional hospital for the island of Menorca, Spain.
Subjects: 1,075 patients who were admitted to Mateu
Orfila Hospital (Menorca) who had laboratory studies
and a nutritional risk (NR) evaluation available were
studied. Those who had a clinical suspicion of MN or
those at risk were studied.
Intervention: Demographic (age, gender) and clinical
(current weight, normal weight, body mass index, weight
loss, oral intake, presence of intestinal failure, fistula,
renal failure, respiratory infection, urinary infection,
hyperglycaemia, admission to the ICU, hospital stay, days
of parenteral nutrition treatment and reason for admission)
were collected during hospitalisation, as well as
hospital mortality and mortality at 6 months following
discharge. All underwent the NRS-2002 test.
Results: The mean patient age was 67.9 years and
58.3% were men. 62% of patients met the criteria for
manutrition according to the NRS-2002 test. A statistically
significant association was seen between malnutrition
according to the NRS-2002 and intestinal failure,
fistula, renal failure, respiratory infection, hyperglycaemia,
hospital mortality and mortality at 6 months.
Conclusion: Malnutrition affects more than half of the
patients who are admitted to a medium-long admission
hospital and it is associated with increased morbidity and
mortality. The results underscore the need to establish an
update plan and preventative and therapeutic nutritional
follow-up. These measures reduce the rate of avoidable
complications and save the costs associated with them.
