OBJECTIVES: A venous thromboembolism (VTE) is a blood clot that occurs secondary to vessel wall injury often from a central line insertion. Enoxaparin is often considered a first-line treatment in pediatrics for VTE due to its favorable kinetic profile. Enoxaparin monitoring for pediatric patients is accomplished through anti-Xa monitoring in which monitoring practices may vary between institutions. The objective of this study is to evaluate covariates in pediatric patients to determine which variables are most likely to be associated with enoxaparin dose changes as a result of anti-Xa monitoring. METHODS: A single center, retrospective chart review was conducted in pediatric patients treated with enoxaparin for VTE over a 10-year period and who were assessed to determine covariates that lead to dose changes based on anti-Xa levels. Secondary outcomes described monitoring patterns at the University of New Mexico Children's Hospital. RESULTS: Sixty-eight patients met inclusion criteria in which results showed that patients aged 2 to 5.9 months (p = 0.026), who had critical care status (p = 0.009), and who were of Native American ethnicity (p = 0.016) were likely to have an enoxaparin dose change at least once during their treatment regimen. The mean number of levels drawn were 7.5 per patient over a 6- to 12-week period, and doses were not frequently changed based on a confirmatory lab draw. However, many doses were adjusted based on the week 1 post-therapeutic level. CONCLUSIONS: Patients of Native American ethnicity, younger than 6 months, and those admitted to the PICU were likely to have dose changes based on anti-Xa levels. Copyright.
