Rationale: Aspiration pneumonia is a serious complication associated with prolonged hospitalization and increased mortality, particularly in patients receiving nutritional support (1). We aimed to identify the factors associated with aspiration pneumonia in hospitalized patients receiving nutritional therapy.
Methods: Demographic data, nutritional routes, and nutrition-related complications of 1,420 hospitalized patients were evaluated in a university hospital.
Results: Patients received either enteral (85.9%, n=1220) or enteral+parenteral nutrition (14.1%, n=200). 56 (3.9%) patients had aspiration pneumonia. Those with aspiration pneumonia were significantly older, more likely to have regurgitation and vomiting (p=0.009, p<0.01, p<0.01, respectively). Mechanical complications like tube obstruction and dislodgement appeared to be more common (p=0.031, p<0.01) in the aspiration group. The rate of patients who achieved ≥60% of their calorie targets was significantly lower in the aspiration group (p<0.001). In the logistic regression analysis, only vomiting was a statistically significant predictor (OR=7.19, 95% CI: 3.09–16.74, p<0.001).

Conclusion: Older age, vomiting, regurgitation, and mechanical feeding complications were more common among patients with aspiration pneumonia. Prospective studies are needed to further explore these associations.
