668 Early Enteral Nutrition in Geriatric Burn Patients: Is There a Benefit?

Abstract

Abstract Introduction Nutrition is a critical component of acute burn care and wound healing. There is no consensus over the appropriate timing of initiating enteral nutrition (EN) in geriatric burn patients. The aim of our study was to assess the impact of early EN on outcomes in geriatric burn patients. We hypothesized that early EN is associated with improved outcomes. Methods We performed a 2-year (2015–2016) analysis of the ACS-TQIP and included all older adult (age ≥65years) burn patients who received EN. Patients were stratified into two groups based on timing of initiation of EN: Early-EN (< 24 hrs) vs. Late-EN (≥ 24 hrs). We performed propensity score matching (1:2 ratio) to control for possible confounding variables including demographics, comorbidities, injury parameters, height and body weight. Outcome measures were in-hospital; complications, hospital and ICU length of stay, and mortality. Results A total of 593,818 trauma patients were analyzed, of which 447 patients were matched (Early-EN: 159 vs Late-EN: 318). Mean age was 44±22, 75% were males, and median ISS was 29 [26–36] and mean total body burn surface area (TBSA) was 15±5%. There was no significant difference between the two groups in terms of age (p=0.99), gender (p=0.60), race (p=0.91), ISS (p=0.43), GCS (p=0.85), TBSA (p=0.51), height (p=0.71), and weight (p=0.61). Overall, the complications rate was 40%, median hospital LOS was 25 [15–36] days, median ICU LOS was 15 [8–26] days and mortality rate was 16%. Patients in the early ED group had significantly lower rate of complications and mortality Table 1. At the same time, patients in the early group had lower hospital length of stay (23[12–36] vs. 26[16–38], p=0.013) and ICU length of stay (12[8–24] vs. 16[8–26], p=0.025). Conclusions In our propensity matched cohort of geriatric burn patients, early EN was associated with improvement in outcomes. The cumulative benefits observed may warrant incorporating early EN as part of intensive care protocols. Applicability of Research to Practice Geriatric patients are a special subset of the population that require additional considerations. Our research highlights the impact of early enteral nutrition on different in hospital outcomes. This is an area of constant debate, our study shows that early enteral nutrition in geriatric burn patients is associated with improved outcome. We found this applicable in most of our patients and thus it might warrant further incorporation in ICU burn protocols.
