| description | OBJECTIVES/SPECIFIC AIMS: Chronically elevated cytokines from un-abating low-grade inflammation in heart failure (HF) results in Protein-Energy Malnutrition (PEM). However, the impact of PEM on clinical outcomes of admissions for HF exacerbations has not been evaluated in a national data. METHODS/STUDY POPULATION: From the 2012-2014 Nationwide Inpatient Sample (NIS) patient’s discharge records for primary HF admissions, we identified patients with concomitant PEM, and their demographic and comorbid factors. We propensity-matched PEM cohorts (32,771) to no-PEM controls (1:1) using a greedy algorithm-based methodology and estimated the effect of different clinical outcomes (SAS 9.4). RESULTS/ANTICIPATED RESULTS: There were 32,771 (~163,885) cases of PEM among the 541,679 (~2,708,395) primary admissions for HF between 2012 and 2014 in the US. PEM cases were older (PEM:76 vs. no-PEM:72 years), Whites (70.75% vs. 67.30%), and had higher comorbid burden, with Deyo-comorbidity index >3 (31.61% vs. 26.30%). However, PEM cases had lower rates of obesity, hyperlipidemia and diabetes. After propensity-matching, PEM was associated with higher mortality (AOR:2.48[2.31-2.66]), cardiogenic shock (3.11[2.79-3.46]), cardiac arrest (2.30[1.96-2.70]), acute kidney failure (1.49[1.44-1.54]), acute respiratory failure (1.57[1.51-1.64]), mechanical ventilation (2.72[2.50-2.97]). PEM also resulted in higher non-routine discharges (2.24[2.17-2.31]), hospital cost ($80,534[78,496-82,625] vs. $43,226[42,376-44,093]) and longer duration of admission (8.61[8.49-8.74] vs. 5.28[5.23-5.34] days). DISCUSSION/SIGNIFICANCE OF IMPACT: In the US, PEM is a common comorbidity among hospitalized HF subjects, and results in devastating health outcomes. Early identification and prevention of PEM in heart failure subjects during clinic visits and prompt treatment of PEM both in the clinic and during hospitalization are essential to decrease the excess burden of PEM. |
