3423 Poorer Outcomes Among Septic Patients with Protein Energy Malnutrition

OBJECTIVES/SPECIFIC AIMS: Protein Energy Malnutrition (PEM) could compromise the body’s defense systems resulting in sepsis, which further depletes calorie stores. Among hospitalized patients, we investigate 1) the relationship between PEM and sepsis, 2) the impact of PEM on trends in mortality from sepsis, and 3) the influence of PEM on clinical outcomes of sepsis. METHODS/STUDY POPULATION: Using the 2014 Healthcare Cost and Utilization Project - Nationwide Inpatient Sample (NIS) patient’s discharge records, we identified patients with sepsis, PEM, and other clinical conditions with ICD-9-CM codes. After stratifying sepsis into two: uncomplicated (without shock) and complicated (with shock), we estimated the adjusted odds (aOR) of developing sepsis (total, uncomplicated and complicated) with PEM. Then, we selected hospitalizations with sepsis from 2007-2014 years of the HCUP-NIS, and calculated the trend in mortality from sepsis, stratified by PEM status, as an effect modifier. Finally, we matched PEM to no PEM (1:1) using a greedy algorithm-based propensity methodology and estimated the effect of having mortality, complicated sepsis and 10 other clinical outcomes and healthcare utilization (SAS 9.4). RESULTS/ANTICIPATED RESULTS: PEM was associated with higher odds for sepsis (aOR:3.97[3.89-4.05]), and complicated vs. uncomplicated sepsis (1.74[1.67-1.81]). Although mortality in sepsis has been trending down from 2007-2014 (−1.19%/year, p-trend<0.0001), the decrease was less pronounced among those with PEM vs. no-PEM (−0.86%/year vs. −1.29%/year, p-value < 0.0001). After propensity matching, PEM was associated with higher mortality (1.35[1.32-1.37]), cost ($160,724[159,517-161,940] vs. $86,650[85,931-87,375]), length of stay (14.76[14.68-14.84] vs. 8.49[8.45-8.56] days), and worse outcomes in general. DISCUSSION/SIGNIFICANCE OF IMPACT: PEM is a risk factor of sepsis and associated with poorer outcomes among septic patients. A concerted effort involving primary care physicians, nutritionists, nurses in identifying, preventing, and treatment of PEM in the community-dwelling individuals before hospitalization might mitigate against these devastating outcomes.
