Malnutrition is prevalent in cardiac surgery and poor nutritional status and decreased mobility leads to adverse outcomes in elderly cardiac surgery patients. This retrospective study was designed to assess the effects of pre-operative nutritional and activities of daily living status to post-operative length of hospital stay (LOS) and mortality, in patients undergoing elective coronary artery bypass grafting (CABG) surgery in 65 year-olds and over with permission of the relevant institution. Method: In the study, a total of 101 patients older than 65 years and over were evaluated. All patients were included in the study that could be reached to their records who evaluated with Barthel Index (BI) for activities of daily living (ADL) and Mini Nutritional Assessment (MNA) for nutritional status. These results were compared with LOS and mortality rate. Results: The incidence of malnutrition was 10.9% and the incidence of being at risk for malnutrition was 44.6% in all patients. We found a negative correlation between BI and LOS (r=-021, p=0.03). We observed no difference between well- nourished and malnourished patients with regard to LOS. There was no patient who died in hospital after bypass surgery. Furthermore, no factor was found to be a good predictor of LOS. Conclusion: Bad ADL status affect the length of hospital stay in our patients. Pre-operative assessment of nutritional and ADL status in patients with advanced age group who underwent coronary by-pass surgery is important.
