OBJECTIVES: To determine the usefulness of the Mini Nutritional Assessment (MNA)
and plasma amino acid analysis in predicting the formation of pressure ulcers
(PUs) in inpatients.
DESIGN: Prospective, observational cohort study with a mean observation period of
62.2 ± 86.4 days.
SETTING: Intermediate and acute care wards of a hospital in rural Japan.
PARTICIPANTS: Inpatients with an average age of 85.0 ± 7.6 (N = 422).
MEASUREMENTS: Mini Nutritional Assessment, Subjective Global Assessment (SGA),
Braden Scale (PU prognostic score), PU formation, and biochemical analysis
including plasma amino acid concentrations.
RESULTS: PUs developed in 7.1% of participants. A MNA score of less than 8 was
more sensitive than a rating of moderate or severe malnourishment on the SGA
combined with a Braden Scale score of less than 15 in predicting future PUs. The
area under the receiver operating characteristic curve (AUC) of the MNA was
superior to that of the Braden Scale. The Braden Scale nutrition subscore had the
lowest AUC of the six Braden Scale subscores. Individuals who developed PUs had
significantly lower plasma arginine concentrations than those who did not.
CONCLUSION: Mini Nutritional Assessment was able to predict the development of
PUs. A MNA score of less than 8 performed better than the SGA, Braden Scale, and
plasma arginine levels in predicting PU development. Although lower plasma
arginine concentration at time of admission was associated with PU development,
the AUC for arginine was not significantly different from 0.50. The findings from
this prospective study support the use of nutritional assessment in inpatients to
predict PU risk and target appropriate interventions.
