Abstract

Malnutrition is predictive of poor outcomes after trauma. Side effects of both pain and narcotics often limit postoperative dietary intake increasing nutritional deficiencies and limiting wound healing. The purpose of this study was to compare the predictive ability of a dietician nutritional evaluation and a patient reported nutritional screening tool for post-operative complications after musculoskeletal trauma. Adults with operative pelvis or long bone fractures were prospectively enrolled in a single-blinded RCT and included in this analysis. Subjects were evaluated with the Patient Generated Subjective Global Assessment (PG-SGA) survey at baseline. Dietician Nutritional Assessment Screening (NAS) was performed for patients ≥65 years with low Albumin or Vitamin D, or admitted to the ICU. Complication analysis included subjects having minimum 6-month follow-up and/or ≥1 complication within six months. Spearman’s Correlation was used to evaluate agreement between screening methods. Comparison using X analysis was done of complications between pre-operative assignment of malnutrition for each screening tool. Agreement of NAS and self-reported PG-SGA for 265 subjects demonstrated a weak correlation of rho = 0.23, P = 0.0002. Neither screening method had significant correlation for rates of non-union, mortality, medical, or surgical complications between designations of malnutrition (all P > .05). Among study subjects, incidence of those having a medical or surgical complication not screened by a dietician was 31.3% and 37.7% respectively. Results indicate inconsistency in methods for assigning malnutrition in trauma population. Additionally, designation of malnutrition by either method was not associated with post-operative complication rates. The high incidence of those with a complication who were not evaluated by a dietician during initial hospitalization (1/3rd) support the need to develop better methods for screening malnutrition after trauma.
