    Creation of the first Hartford Consensus compliant elementary school in the USA
    (BMJ Publishing Group, 2016) Ramly, Elie; Bohnen, Jordan D; Fagenholz, Peter; Yeh, Dante; Velmahos, George; DeMoya, Marc; Kaafarani, Haytham; Butler, Katheryn; Lee, Jarone; King, David
    Background: The Hartford Consensus established a framework for minimizing deaths due to mass shootings, specifically eliminating preventable deaths due to limb exsanguination. Two major principles defined within this framework are (1) redefining the first responder role and (2) the ubiquitous availability of proper training in application of hemorrhage control techniques, including tourniquets. We hypothesized that this hemorrhage control posture could be fully translated into an elementary school. Methods: Following institutional review board approval, all teachers at a prekindergarten through 8th grade elementary school underwent short, intensive instruction on their role as a first responder, as well as indications and proper technique for hemorrhage control and tourniquet application for limb exsanguination. All teachers self-reported their confidence in their role as a first responder as well as tourniquet application indications and technique before and after instruction. Following instruction, teachers were evaluated on proper tourniquet application technique on a simulated limb to assess competence. Results: 26 elementary school teachers and 2 administrative staff underwent training. All reported low confidence in their role as a first responder and in tourniquet application indication and technique before training. Following training, all teachers reported high confidence. Testing demonstrated all teachers were competent in the tourniquet application technique. Following training, each classroom was equipped with a purpose-made commercial tourniquet, and a dedicated hemorrhage control bag was placed in the school's central administrative office. Conclusions: All teachers were successfully trained to act as first responders and in correct hemorrhage control techniques, which was verified by testing. This is the first elementary school to universally adopt a hemorrhage control posture to eliminate preventable deaths from limb exsanguination advocated by the Hartford Consensus.

    The Deyo-Charlson and Elixhauser-van Walraven Comorbidity Indices as predictors of mortality in critically ill patients
    (BMJ Publishing Group, 2015) Ladha, Karim S; Zhao, Kevin; Quraishi, Sadeq; Kurth, Tobias; Eikermann, Matthias; Kaafarani, Haytham; Klein, Eric N; Seethala, Raghu; Lee, Jarone
    Objectives: Our primary objective was to compare the utility of the Deyo-Charlson Comorbidity Index (DCCI) and Elixhauser-van Walraven Comorbidity Index (EVCI) to predict mortality in intensive care unit (ICU) patients. Setting: Observational study of 2 tertiary academic centres located in Boston, Massachusetts. Participants: The study cohort consisted of 59 816 patients from admitted to 12 ICUs between January 2007 and December 2012. Primary and secondary outcome For the primary analysis, receiver operator characteristic curves were constructed for mortality at 30, 90, 180, and 365 days using the DCCI as well as EVCI, and the areas under the curve (AUCs) were compared. Subgroup analyses were performed within different types of ICUs. Logistic regression was used to add age, race and sex into the model to determine if there was any improvement in discrimination. Results: At 30 days, the AUC for DCCI versus EVCI was 0.65 (95% CI 0.65 to 0.67) vs 0.66 (95% CI 0.65 to 0.66), p=0.02. Discrimination improved at 365 days for both indices (AUC for DCCI 0.72 (95% CI 0.71 to 0.72) vs AUC for EVCI 0.72 (95% CI 0.72 to 0.72), p=0.46). The DCCI and EVCI performed similarly across ICUs at all time points, with the exception of the neurosciences ICU, where the DCCI was superior to EVCI at all time points (1-year mortality: AUC 0.73 (95% CI 0.72 to 0.74) vs 0.68 (95% CI 0.67 to 0.70), p=0.005). The addition of basic demographic information did not change the results at any of the assessed time points. Conclusions: The DCCI and EVCI were comparable at predicting mortality in critically ill patients. The predictive ability of both indices increased when assessing long-term outcomes. Addition of demographic data to both indices did not affect the predictive utility of these indices. Further studies are needed to validate our findings and to determine the utility of these indices in clinical practice.
