Unnecessary testing may lead to patient harm, inappropriate treatments, and/or increased cost. Per the Endocrine Society, in conjunction with Choosing Wisely, 1,25-dihydroxyvitamin D (1,25-OH D) should not be measured unless a patient has hypercalcemia or decreased kidney function. This study sought to evaluate overutilization of 1,25-OH D at Cincinnati Children's Hospital Medical Center. We queried EPIC for all 1,25 OH vitamin D tests drawn in all patients (inpatient and outpatient) between 01/01/2021 and 12/31/2021. We then cross-referenced each test with all patient ICD10 codes associated with each patient’s chart. Appropriate ordering was defined as the patient having an ICD10 code related to calcium disorders or renal disease (531 codes included, data not shown). Out of a total of 1,057 1,25-OH D tests ordered, we found that only 19.4 percent were in patients whose chart contained a code that clinically would indicate testing. Further analysis showed most of these tests were obtained by psychiatry (22.7%) and community general pediatricians (14.6%) and not by endocrinology (12.5%) or nephrology (2.2%) providers. We will use this as baseline data to design quality improvement interventions to reduce unnecessary ordering of 1,25 OH vitamin D, including an ordering pathway in Epic to provide point of care education and guidance regarding appropriate Vitamin D test selection. In summary, inappropriate ordering of 1,25 vitamin D is common, likely due to misunderstanding of the best test to determine vitamin D sufficiency. Presentation: Thursday, June 15, 2023
