An electronic alert to decrease Kayexalate ordering

Area of Science:

• Pharmacology
• Health Informatics
• Patient Safety

Background:

• Sodium polystyrene sulfonate (Kayexalate) is a widely used cation-exchange resin for treating hyperkalemia.
• Recent safety concerns have emerged regarding Kayexalate use.
• A need exists to mitigate potential risks associated with Kayexalate therapy.

Purpose of the Study:

• To evaluate the impact of an electronic alert system on Kayexalate prescribing patterns.
• To assess the effectiveness of technology in addressing medication safety concerns.

Main Methods:

• Implementation of an electronic alert system at a tertiary care academic medical center.
• Prospective analysis of Kayexalate prescription data (orders per month and grams per month).
• Comparison of prescribing data from one year before and one year after alert implementation.

Main Results:

• A 38% absolute reduction in the mean number of Kayexalate orders per month (123 to 76).
• A 43% absolute reduction in the mean grams of Kayexalate prescribed per month (3332 to 1885).
• Statistical significance (p < 0.001) was observed for both reductions.

Conclusions:

• Electronic alerts are an effective tool for reducing Kayexalate ordering.
• This intervention can help mitigate safety concerns associated with Kayexalate.
• The study demonstrates the utility of health informatics in improving medication safety.
