Implementation and safety evaluation of autoverification for select low-risk, high-volume medications in the emergency department

Abstract

Abstract Purpose Use of autoverification has decreased in many emergency departments (EDs) with the expansion of emergency medicine (EM) pharmacists. Few studies have evaluated ways to prioritize verification of medications. Here we describe a process to design, implement, and measure the safety of autoverification of low-risk, high-volume medications. Summary A 3-month retrospective review of medications ordered and administered in the ED generated a list of medications to be considered for autoverification. Concurrently, a novel risk stratification tool was created to identify low-risk medications. Taking these together, medications that were high volume and low risk were considered potentially autoverified medications (PAMs). To evaluate the safety of PAMs, a retrospective review of the ED medication orders placed before implementation of autoverification was performed. A total of 7,433 medication orders were reviewed. Of these, 3,057 orders (41%) were identified as PAMs. EM pharmacists verified 2,982 (97.5%) of the orders without changes. Of the remaining 93 orders that were modified or discontinued and met autoverification criteria, only 2 (0.07%) were identified as potentially inappropriate for autoverification. Conclusion Low-risk, high-volume medications can be safely autoverified in the ED by using a systematic approach to order selection. Using these methods can provide large decreases in verification volume, close to 41%, without compromising patient safety.
