Identification of Predictors of Abnormal Calcium Magnesium and Phosphorus Blood Levels in the Emergency Department: A Retrospective Cohort Study

摘要

With rising healthcare costs limiting access to care, the judicious use of diagnostic tests has become a critical issue for many jurisdictions. Calcium, magnesium and phosphorus serum levels are regularly performed tests in the emergency department, but their clinical relevance have come into question. Authors sought to determine risk factors that could predict abnormal calcium, magnesium and phosphorus serum levels, as well as identify patients who may need corrective interventions.
