Purpose of the Study
The study aimed to validate a modified SGA Nutrition Assessment tool and find out which criteria will determine the nutritional status and nutritional risk of Medical and Surgical patients in two government hospitals in the Philippines.


In this cross sectional observational research, two DOH retained hospitals were selected to use a nutrition assessment form among medical and surgical patients. The study was conducted for a period of one month. Letters of Intent were forwarded to the Two DOH Retained hospitals for approval to conduct the study in their Institution. A letter of request seeking for approval from the DOH National Center for Health Facility Development was forwarded to seek participation of DOH retained hospitals Dietitians in this study. After initial coordination with the two hospitals and upon submission of all the necessary requirements of the Ethics and Research Committees of both hospitals the research study started with a one day general orientation with the Nursing Service, Medical Staff and the Dietary Staff. Other than the Staff Dietitians of the respective two hospitals, about 6 DOH Retained hospital Dietitians from Manila, Quezon City and Rizal participated in the data gathering. A one day orientation program was executed for the two hospitals, renowned speakers with expertise in Nutrition Support were invited to provide lectures and updates .After the general lecture, a workshop was conducted on the second day which aimed to teach the participants how to use the Modified SGA tool. Then followed by an inter rater determination between each of the Dietitians. Prior to the end of the study a questionnaire was gi-1e to all tfie Dietitians to evaluate the applicability and acceptability of the modified SGA tool. The data of this study was analyzed using Stata 11 and alpha level of significance was set at 0.05. The statistical analysis included frequency and percentage for the categorical data; mean and standard deviation for continuous normal data, and median and inter­quartile range for continuous non-normal data. For the predictive values, this is the likelihood that an index correctly predicts the presence or absence of malnutrition or disease. The predictive value was further subdivided into the positive predictive value and the negative predictive value. Significant differences for the percentages were tes􀀙ed using chi-square test while Fisher's exact test when there is violation on assumptions for chi-square test. T-test and Mann-;Whitney U test were used to test the mean and median between two groups, respectively. Moreover, signed test were used to compare the within total caloric intake of patients taken by dieticians and attending physicians.


All of the SGA criteria such as weight loss, food intake, gastro symptoms, functional capacity, nutritional stress (disease and its relation to nutrition), physical examination muscle wasting), and Edema/ascites were all significant predictors of nutritional status. The Modified SGA tool had a sensitivity of 93 % and a specificity of 58%. The prevalence of Mal11utrition for both hospitals was 62 %.


The modified SGA Nutrition Assessment tool is a good predictor for Nutritional Risk whici1 can be used among medical and surgical patients confined in DOH retained hospitals in the Philippines.
