OBJECTIVES: Effects of malnutrition in patients underwent abdominal resection surgery (ARS) are often disregarded. This abstract aims to report nutritional supplement (NS) usage in patients underwent abdominal resection surgery (ARS) for non-oncological conditions in Turkey using general health insurance (GHI) reimbursement database of Social Security Institute. METHODS: Turkish GHI system has covered 98% of total population of Turkey. Therefore statistics obtained via the GHI database are highly representative of the population of Turkey. From GHI database, patients who underwent any kind of ARS for non-oncological conditions between 1 January 2009 and 31 December 2013 were included to analysis. RESULTS: In GHI database, 5,787 patients (mean age: 55.0 years, 45.6% female) met selection criteria of this abstract. NS was used for 6.6% of the patients during hospitalization (median 12.0 days) and NS was used median 2.0 days during hospitalization. Mortality rate was 24.2% during hospitalization. Of the 4,384 discharged patients, 1.2% used NS during outpatient follow-up duration and 0.8% used NS more than 30 days based on prescribing data. Moreover 97.6% of patients who received NS during hospitalization did not continue NS usage during outpatient follow-up duration. Median survival durations were 60.0 and 25.1 months in patients not used NS and used NS, and 12-month survival rates were 65.0% and 51.0%, respectively. CONCLUSIONS: The abstract showed NS usage patterns in patients who underwent ARS for non-oncological conditions in Turkey. Malnutrition risk increased with ARS due to type of intervention, but ratio of NS usage in daily practice is low and usage duration is relatively short. Moreover survival analyses revealed that NS seems to be preferred for complicated patients. In conclusion all patients underwent ARS should be evaluated for malnutrition and treated accordingly to avoid medical and economic burden.
