In this cohort study of trauma patients, hypercalcemia was less common than hypocalcemia; however, hypercalcemia was associated with worse mortality at all time points. Blood product consumption was higher among those with hypercalcemia or hypocalcemia compared with eucalcemia but was similar among those with any calcium derangement. Prospective interventional trials are needed to understand the implications of empiric treatment.
Schauer et al. (Wed,) studied this question.
