Predictors and inpatient outcomes of aspiration pneumonia in patients with percutaneous endoscopic gastrostomy tube: An analysis of national inpatient sample
Abstract
BACKGROUND
Percutaneous endoscopic gastrostomy (PEG) tubes are commonly inserted to provide a route for enteral feeding in patients who are unlikely to have adequate oral intake for prolonged periods of time. This study aims to determine the incidence of aspiration pneumonia among PEG tube patients.
METHODS
We conducted a retrospective analysis of NIS database records (October 2015 to December 2020) for patients with PEG. Primary and secondary outcomes were assessed using ICD-10-CM/PCS codes.
RESULTS
We identified a total of 2,053,560 weighted hospitalizations involving patients with PEG tube. Those with aspiration pneumonia were older (mean age 67.01 vs. 63.85, p<0.01) and were predominantly male. At baseline, the aspiration pneumonia group had higher rates of dementia (AOR 1.22, 95% CI: 1.19-1.24), malnutrition (AOR 1.13, 95% CI: 1.11-1.15), cerebrovascular disease (AOR 1.29, 95% CI 1.25-1.33), cardiac arrhythmias (AOR 1.05, 95% CI 1.03-1.08), congestive heart failure (AOR 1.20, 95% CI 1.17-1.24), COPD (AOR 1.18, 95% CI 1.15-1.20), paralysis (AOR 1.06, 95% CI 1.03-1.09), alcohol abuse (AOR 1.12, 95% CI 1.07-1.17), and psychoses (AOR 1.07, 95% CI 1.02-1.13). Those with aspiration pneumonia exhibited increased mortality (p<0.01, AOR 1.59, 95% CI 1.54-1.65), higher incidence of severe sepsis (AOR 2.03, 95% CI 1.98-2.07) and longer hospital stays, and accrued greater hospital charges (p<0.01). Notably, while GERD is typically considered a risk factor for AP, our findings…
