| Summary: | Background: Hospital malnutrition still become main problem in health area.
78,3% patients found to be malnourished in hospital care. Group of patients with
highest prevalence of malnutrition in surgical patients (52,5%) and geriatric
patients (among other age-groups). Many research proved that nutritional status
in patients significantly correlated with length of stay and post operative
complications (including post operative infection). MNA and GNRI are methods
that can be used for assessing nutritional status in geriatric patients.
Objective: To validate GNRI as a nutritional assessment tool compare with MNA
and to analyze the association between nutritional status of patients with length
of stay and post operative complication.
Method: This is an analytic cross sectional study that is held in Adult Surgery
Department of RSUP Dr. Sardjito Yogyakarta along March-November 2012. 67
geriatric patients with surgical treatment are assessed their early nutritional status
with MNA and GNRI. Followed by record of their date of admission and
submission and also their incidence of post operative infection (taken from
medical record data). Validity test is done by calculating sensitivity, specificity and
MSS value of GNRI and bi-variate analyze with chi square.
Results: Based on its validity test GNRI sensitivity is 82,14% and specificity
63,64% (MSS 145,78%). Patients with nutritional risk status with longer length of
stay is 58,9% assessed with MNA and 54% with GNRI. Patients with no risk of
malnutrition assessed with MNA and having no post operative infection is 72,7%
and 70,6% while assessed with GNRI. Chi square analyze shows no association
between nutritional status with length of stay and post operative infection in
geriatric patients assessed with GNRI and MNA (p>0,05).
Conclusion: There are no association between nutritional status with length of stay and post operative infection in geriatric patients assessed with GNRI and MNA.
