Background: Trauma increases risk for venous thromboembolism (VTE) and obesity is a known independent risk factor for VTE development. Currently, no consensus on an optimal prophylactic dosing strategy for morbidly obese trauma patients exists. The objective of this study is to evaluate the effectiveness and safety of a BMI-stratified dosing strategy for VTE prophylaxis in morbidly obese trauma patients. Methods: This was a single center, retrospective cohort study of adult major trauma patients with a body mass index (BMI) of ≥40 kg/m2 admitted to the surgical-trauma intensive care unit from April 2014 to July 2020. Patients included were those who received enoxaparin 40 mg subcutaneously (SQ) every 12 hours (Q12H) for BMI of 40 to 49.9 kg/m2 or 60 mg SQ Q12H BMI ≥ 50 kg/m2 (per protocol), or enoxaparin 40 mg SQ Q12H for BMI of 40 to 49.9 kg/m2 (non-protocol). The primary endpoint was confirmed incidence of VTE. Secondary endpoints included occurrence of deep vein thrombosis (DVT) or pulmonary embolism (PE) during hospitalization, bleeding events, intensive care unit (ICU) and hospital length of stay (LOS) and hospital mortality. Results: One hundred forty-five morbidly obese major trauma patients were included, with 123 patients (84.8%) in the per-protocol group. The primary outcome of in-hospital VTE did not occur in any patients in this group. Bleeding events occurred in 3 patients (2.7%) with a BMI of 40 to 49.9 kg/m2 and in 2 patients (16.7%) with a BMI of ≥50 kg/m2 ( P = .064). Twenty-two patients in the non-protocol group were reviewed. One VTE event (4.5%) and no bleeding events occurred in this group. Median ICU LOS was 5 days, and hospital LOS was 11 days for the entire study group. Conclusions: Administration of enoxaparin 40 mg SQ Q12H to morbidly obese major trauma patients with a BMI of 40 to 49.9 kg/m2 and enoxaparin 60 mg SQ Q12H in those with a BMI of ≥50 kg/m2 resulted in low rates of VTE and bleeding events in the current study. However, future larger studies using this BMI-stratified dosing strategy are necessary to confirm these findings.

Background: Tech-Check-Tech (TCT) allows a pharmacy technician to perform the final check of medications prepared by another technician. The effect of a TCT program on the time required to process medications in a hospital pharmacy has not been previously reported.
