A multifaceted approach in leveraging electronic health record tools for safe inpatient use of concentrated U-500 insulin

Abstract

Purpose: The Institute for Safe Medication Practices classifies subcutaneous insulin as a high-risk medication. Concentrated U-500 insulin carries additional risks in comparison to conventional U-100 insulin, as the 5-fold more concentrated nature of this product, limitations to insulin pen dosing, and various devices for dose measurement may lead to miscommunication of patient-reported doses, resulting in downstream errors in ordering, verification, or administration. We describe a multifaceted approach to leveraging technical tools within the electronic health record (EHR) for U-500 insulin use.

Summary: At Cleveland Clinic, the U-500 insulin use process evolved in a number of phases using EHR tools. Phase 1 included new clinical decision support and documentation tools during order entry, including a customized alert that fired during order entry recommending that the prescriber order a consult with endocrinology and requiring the prescriber to provide the patient's home insulin measuring device and the source of the patient's reported home dose. In order verification, a customized alert fired directing the pharmacist to contact the patient or patient's nurse and validate the information provided by the prescriber. Phase 2 involved transitioning dispensing of patient-specific doses from tuberculin syringes to U-500 insulin syringes. Phase 3 transitioned to use of U-500 insulin pens and included automatic dose rounding of ordered doses down to the nearest 5 units, and an additional customized pharmacist alert intended for cost conservation was added to fire if the patient had a recent administration of U-500 insulin documented, directing the pharmacist to determine whether the nurse needed a new pen dispensed.

Conclusion: Cleveland Clinic successfully implemented customized tools and processes within the EHR pertaining to the prescribing, verification, dispensing, and administration of U-500 insulin.
