Why EHRs Alone Don’t Solve Medication Prep Pain Points
Electronic Health Records (EHRs) are the backbone of modern hospital IT, but they often fail clinicians in the moments that matter most. Evidence continues to show that EHRs contribute to workflow inefficiencies, cognitive overload, and even new safety risks, especially in high-acuity environments like emergency departments.
In a 2023 study, Harmon et al. surveyed 304 emergency nurses and found that unintended consequences of EHR use created patient safety threats on a weekly to monthly basis. Rather than simplifying work, EHR workflows can add complexity at exactly the wrong time, during time-critical clinical decisions and medication preparation.
The Real-World Impact of EHR-Driven Workflows
1. Too Many Clicks, Too Little Support
Shan et al. found that interruptions during EHR tasks significantly increased nurses’ mental workload and were associated with errors and near-errors. When similar interruptions occur during medication preparation, the risk of missed information, workarounds, and unsafe shortcuts rises.
2. More Digital ≠ Less Error
Hamad et al. found that reported medication incidents increased after EHR implementation in a HIMSS Stage 6 hospital. They attribute this primarily to improved detection and reporting within a more structured medication management process, not necessarily to more harm. Digitization alone doesn’t guarantee safer medication processes, it also makes errors more visible.
3. The Burden of Cognitive Load
Emergency nurses already juggle high-acuity patients, frequent interruptions, and dynamic patient loads. Adding EHR complexity compounds this strain. Harmon et al. reported that EHR-related unintended consequences contribute to increased cognitive load for nurses, underscoring that EHR design can amplify, rather than relieve, cognitive burden.
What the Evidence Shows: CDSS Works, When It Works for Clinicians
Clinical Decision Support Systems (CDSS) embedded in EHRs can significantly reduce errors, when they are designed around clinician workflow.
- A meta-analysis in oncology found that Computer Provider Order Entry (CPOE) systems reduced chemotherapy-related medication errors by 81% (Srinivasamurthy et al., 2021).
- Another review reported that >50% reductions in preventable adverse drug events (ADEs) and medication errors post-CPOE (Nuckols et al., 2014).
- Barcode medication administration (BCMA) systems can reduce medication administration errors by 65-86% (Patient Safety Authority, 2008). However, both the Authority and Grailey et al. (2023) document significant usability challenges and workarounds that can re-introduce risk.
In short: CDSS effectiveness depends on whether the system reduces clinician effort and cognitive load. When it adds friction (extra clicks, irrelevant alerts, unintuitive interfaces), its safety benefits are limited.

From Theory to Practice: Real-World Impact with NurEx
In a recent pilot of NurEx at the McGill University Health Center (MUHC) pediatric emergency department, NurEx was evaluated in live clinical workflows and demonstrated:
- Up to 74% faster medication administration times
- 94% of nurses reported reduced mental effort
- 7,000+ nursing hours saved annually
- 6.4 - 6.6/7 average user satisfaction after only 15 minutes of training
These results reflect what happens when bedside dosing support is designed for nurses first. They were measured in live emergency workflows. And MUHC isn’t alone, hospitals facing similar EHR-driven pain points are turning to targeted decision support to close the last mile gap in medication safety.
The Bottom Line: Don’t Expect Your EHR to Do It All
EHRs are essential, but they’re not optimized for real-time medication decision-making at the bedside.
NurEx is.
By focusing on the most error-prone part of the medication process, preparation and administration, NurEx delivers immediate safety and efficiency gains, with minimal workflow disruption.
