Although use of thromboelastography (TEG) to diagnose coagulopathy and guide clinical decision-making is increasing, relative performance of different TEG methods has not been well-defined. Rapid-TEG (rTEG), kaolin-TEG (kTEG), and native-TEG (nTEG) were performed on blood samples from burn patients presenting to a regional center from admission to 21 days. Patients were categorized by burn severity, mortality, and fibrinolytic phenotypes (Shutdown [SD], Physiologic [PHYS], and Hyperfibrinolytic [HF]). Manufacturer ranges and published TEG cutoffs were examined. Concordance correlations (Rc) of TEG parameters (R, α-angle, maximum amplitude [MA], LY30) measured agreement and Cohens Kappa (κ) determined interclass reliability. Patients (n = 121) were mostly male (n = 84; 69.4%), with median age 40 years, median TBSA burn 13%, and mortality 17% (n = 21). Severe burns (≥40% TBSA) were associated with lower admission α-angle for rTEG (P = .03) and lower MA for rTEG (P = .02) and kTEG (P = .01). MA was lower in patients who died (nTEG, P = .04; kTEG, P = .02; rTEG, P = .003). Admission HF was associated with increased mortality (OR, 10.45; 95% CI, 2.54-43.31, P = .001) on rTEG only. Delayed SD was associated with mortality using rTEG and nTEG (OR 9.46; 95% CI, 1.96-45.73; P = .005 and OR, 6.91; 95% CI, 1.35-35.48; P = .02). Admission TEGs showed poor agreement on R-time (Rc, 0.00-0.56) and α-angle (0.40 to 0.55), and moderate agreement on MA (0.67-0.81) and LY30 (0.72-0.93). Interclass reliability was lowest for R-time (κ, -0.07 to 0.01) and α-angle (-0.06 to 0.17) and highest for MA (0.22-0.51) and LY30 (0.29-0.49). Choice of TEG method may impact clinical decision-making. rTEG appeared most sensitive in parameter-specific associations with injury severity, abnormal fibrinolysis, and mortality.

BackgroundElderly (65 and older) fall-related injuries are a significant cause of morbidity and mortality. Although frailty predicts poor outcomes in geriatric trauma, literature comparing frailty scoring systems remains limited. Herein, we evaluated which frailty scoring system best predicts falls over time in the elderly.Materials and methodsAcute surgical patients 65 y and older were enrolled and prospectively observed. Demographics and frailty, assessed using the FRAIL Scale, Trauma Specific Frailty Index (TSFI), and Canadian Frailty Scale (CSHA-CFS), were collected at enrollment and 3 mo intervals following discharge for 1 y. Surveys queried the total number and timing of falls. Changes in frailty over time were assessed by logistic regression and area under the curve (AUC).ResultsFifty-eight patients were enrolled. FRAIL Scale and CSHA-CFS scores did not change over time, but TSFI scores did (P ≤ 0.01). Worsening frailty was observed using TSFI at 6 (P ≤ 0.01) and 12 mo (P ≤ 0.01) relative to baseline. Mortality did not differ based on frailty using any frailty score. Increasing frailty scores and time postdischarge was associated with increased odds of a fall. AUC estimates with 95% CI were 0.72 [0.64, 0.80], 0.81 [0.74, 0.88], and 0.76 [0.68, 0.84] for the FRAIL Scale, TSFI, and CSHA-CFS, respectively.ConclusionsThe risk of falls postdischarge were associated with increased age, time postdischarge, and frailty in our population. No scale appeared to significantly outperform the other by AUC estimation. Further study on the longitudinal effects of frailty is warranted.

Blood transfusions following major burn injury are common due to operative losses, blood sampling, and burn physiology. While massive transfusion improves outcomes in adult trauma patients, literature examining its effect in critically ill children is limited. The study purpose was to prospectively compare outcomes of major pediatric burns receiving a 1:1 vs. 4:1 packed red blood cell to fresh frozen plasma transfusion strategy during massive burn excision. Children with >20% total body surface area burns were randomized to a 1:1 or 4:1 packed red blood cell/fresh frozen plasma transfusion ratio during burn excision. Parameters examined include patient demographics, burn size, pediatric risk of mortality (PRISM) scores, pediatric logistic organ dysfunction scores, laboratory values, total blood products transfused, and the presence of blood stream infections or pneumonia. A total of 68 children who met inclusion criteria were randomized into two groups (n = 34). Mean age, PRISM scores, estimated blood loss (600 ml (400-1175 ml) vs. 600 ml (300-1150 ml), P = 0.68), ventilator days (5 vs. 9, P = 0.47), and length of stay (57 vs. 60 days, P = 0.24) had no difference. No differences in frequency of blood stream infection (20 vs. 18, P = 0.46) or pneumonia events (68 vs. 116, P = 0.08) were noted. On multivariate analysis, only total body surface area burn size, inhalation injury, and PRISM scores (P < 0.05) were significantly associated with infections.
