BACKGROUND: Intravenous (IV) magnesium sulfate (MgSO4) supplementation is common despite limited indications. Oral magnesium oxide (MgO) is an effective, lower-cost alternative. This project aimed to reduce IV MgSO4 use by 20% among the Internal Medicine (IM) service.

METHODS: Electronic health record (EHR) orders for MgSO4 and MgO within the IM service were replaced with an indication-based EHR order panel. The project team educated clinicians regarding indications for IV MgSO4 and relative costs. The mean of daily 2 g MgSO4 administrations per week and the mean of weekly proportion of 2 g MgSO4 administrations nine months before and after intervention were compared between IM and Emergency Medicine (EM) (control group). Statistical process control analysis was used to assess for special cause variation in daily MgSO4 per week and weekly proportion of MgSO4 administrations.

RESULTS: The mean of daily 2 g IV MgSO4 administrations per week decreased among IM (19.3 vs. 12.1, p < 0.0001) but not EM (3.1 vs. 4.8, p < 0.0001). The mean of weekly proportions of IV MgSO4 administrations decreased among both IM (83.6% vs. 60.7%, p < 0.0001) and EM (97.0% vs. 93.1%, p = 0.0004). For IM, the change in daily MgSO4 per week and weekly proportion of MgSO4 occurred as a discrete initial decline consistent with special cause variation; for EM, changes in both measures were not consistent with special cause variation.

CONCLUSION: Replacing stand-alone IV MgSO4 orders with an indication-based order panel along with clinician education reduced IV MgSO4 administrations and may offer a significant opportunity to reduce low-value care.
