If you’ve ever been part of a clinical trial, you know that data can quickly turn into a mess if it's not well organized. And when you're in a hurry to analyze results, the last thing you need is to waste time matching terms like “headache,” “cephalea,” or “migraine.”

That’s where medical coding integrated into your EDC comes in. It may sound technical, but this feature can save you a lot of work—and more than one literal (and figurative) headache. Today, we’d like to explain why it’s so helpful and how it can make your data management easier throughout your clinical study.

What Is Medical Coding, and Why Does It Matter?

The idea is simple: use a common language.

When each investigator describes the same thing in different words, analyzing the data gets complicated. Medical coding solves this by assigning standardized codes to medical terms, medications, and procedures. It’s done using well-known dictionaries like MedDRA, WHO-Drug, or SNOMED CT.

The result? Everyone speaks the same language—no matter who collects the data or where it comes from.

Benefits of Coding Directly Within the EDC

1. Better Data Quality from the Start

When coding happens at the same time as data entry, errors are caught immediately. You don’t need to wait for the data cleaning team to go over everything later. This means fewer queries and better quality from the ground up.

2. Real Time Savings

Traditional coding involves exporting the data, coding it in another system, importing it back… and hoping everything matches. With integrated coding, this process happens in real time—no delays, no rework.

3. More Consistency Across Sites

Using the same standards for all investigators and patients is key. Coding directly in the EDC helps avoid variation and ensures your data stays reliable and comparable throughout the study.

4. Faster and More Meaningful Analysis

When terms are already correctly coded from the beginning, you can start analyzing sooner—and with more confidence. This is especially important for time-sensitive safety decisions.

5. Easier Regulatory Compliance

Agencies like the FDA and EMA require standardized data. Having integrated coding helps meet these requirements and makes audits and inspections smoother.

What Should a Medical Coding-Enabled EDC Offer?

If you’re going to use this feature, make sure the system provides:

  • Smart search in medical dictionaries, so it can find the right term even if the wording isn’t perfect.
  • Support for multiple dictionaries, like MedDRA, WHO-Drug, and others.
  • Flexible configuration, to define which fields require coding and which dictionary to use.
  • Review and approval workflows, so coders can validate what’s been done.
  • Full traceability, to always know who coded what, and when.

How Does ShareCRF Do It?

At ShareCRF, we know medical coding isn’t just a technical task—it’s a key part of quality control in any clinical trial. That’s why we’ve built tools to make this process easier and more helpful for the people who deal with it every day:

  • Flexible configuration, so you can define exactly which fields require coding and link them to the right dictionary.
  • Progressive coding, which lets you move forward gradually instead of leaving everything until the end.
  • Advanced search, that finds the right term even when it's written in different ways.
  • Collaborative work, with multiple coders working at the same time without stepping on each other’s toes.
  • All in one place, with no need to export and import between different tools.

Final Thoughts

Medical coding integrated into your EDC is no longer a luxury—it’s a smarter way to work.

It reduces errors, saves time, and helps your data make sense right from the start.

Because in the end, every minute saved on data management is a minute you can spend on what really matters: advancing research and taking better care of patients.

If you’re curious, we’d be happy to show you how it works. We offer no-pressure demos. It’s entirely up to you if you want to see it in action.
