In the demanding world of emergency departments, every moment counts. Nowhere is this truer than in the preparation and administration of medications in rapidly decompensating pediatric patients, a process particularly fraught with challenges. Medication errors, unfortunately, remain an ever-present concern, highlighting the need for precise dosing and reliable drug information. In pediatric care, where dosages are weight-dependent and vary significantly from adult standards – and where “on-label” is often a concept difficult to manage along with clinical needs, let’s face it – the margin for error is even narrower.

The intricacies of pediatric medication management demand solutions that integrate into the workflow of the emergency department, ensuring swift and accurate administration. As healthcare professionals grapple with the pressures of time-sensitive situations, as well as systemic pressures, the need for user-friendly tools that enhance efficiency and mitigate the risk of errors has never been more apparent.

In this blog post, we delve into the world of medication dosing apps, with a specific focus on NurEx, a software designed to simplify medication preparation in pediatric settings, and Lexicomp, a renowned drug referential system. By exploring their features, functionalities, and effectiveness within the emergency department workflow, we aim to provide healthcare practitioners with a comprehensive understanding of the tools at their disposal.

What is Lexicomp?

Downsides of Each Tool

  • NurEx:
    • Requires some digital literacy despite fitting nicely in the flow of the ED
    • Does not present all possible information about each medication since it is meant as a point of care tool
  • Lexicomp:
    • Cost: The comprehensive features of Lexicomp come at a price. While many healthcare institutions subscribe to Lexicomp for the benefits it offers, the cost can be a barrier for individual healthcare professionals, especially those in smaller practices or without institutional support.
    • Limited Customization: Lexicomp, despite its extensive capabilities, may have limitations in terms of customization.
    • Internet Dependency: Lexicomp primarily operates as a web-based application, requiring a stable internet connection.


As emergency departments look for ways to reduce medication errors, the combination of NurEx and Lexicomp emerges as a powerful duo to streamline processes, enhance precision, and ultimately improve patient outcomes.

The NurEx software addresses the unique challenges of pediatric care, providing a user-friendly interface that guides healthcare professionals through precise medication dosing. Its integration of all emergency neonatal and pediatric information in one place, seamless calculations, and up-to-date data contribute to reducing cognitive burden and minimizing the risk of errors, crucial factors in time-sensitive situations.

Emergency departments, in their pursuit of reducing cognitive workload, stress, and medication errors, may find value in incorporating the NurEx device alongside Lexicomp in their suite of products. The precision and user-friendly approach of NurEx, coupled with the extensive information and decision support capabilities of Lexicomp, create a synergy that aligns with the demanding nature of emergency pediatric care.
