Abstract only Introduction: Data on the burden of congestive heart failure (CHF) in aspiration pneumonia (AP) patients is sparse. Our aim is to study the burden, morbidity and outcomes of CHF on AP patients. Methods: We queried the National Inpatient Sample (2015 October-2017) to identify admissions for AP in patients with CHF vs without CHF using relevant ICD-codes. Primary outcomes reported were all-cause mortality and pulmonary morbidity. Secondary outcomes included patient disposition, LOS and utilization of hospital resources. Results: We included 14,38,034 aspiration pneumonia (AP) hospitalizations amongst which 3,33,975 had associated CHF (23.2%). AP-CHF cohort often included older (79 [68-87]), white (74.8% vs 72.6%), male (54.7% vs 45.3%) patients admitted non-electively with Medicare insurance at Urban teaching facilities compared to AP only cohort (p<0.001) (Table 1) . AP-CHF cohort was more often associated with valvular disease, pulmonary circulation disease, peripheral vascular disease, chronic pulmonary disease, hypertension (secondary/complicated), diabetes mellitus, hyperlipidemia and obesity compared to AP-only cohort. AP-CHF cohort had lower rates of alcohol abuse, drug abuse and smoking. AP- CHF cohort had higher adjusted odds of all-cause mortality (aOR 1.14 95% CI 1.13-1.15, p<0.001), ARDS (aOR 2.27), respiratory failure (aOR 1.77), severe sepsis with septic shock (aOR 1.34) and requirement of respiratory support (aOR 1.40) compared to AP only cohort. AP-CHF cohort was more often discharged to short-term or intermediate facility and had longer stay with higher hospital charges compared to AP only cohort. Conclusion: Based on our analysis it can be concluded that nearly one-fourth of AP hospitalizations have concomitant CHF and that is associated with higher morbidity, mortality and complications ultimately leading to higher hospital resource utilization.
