eISF Growing Pains: What’s Holding Back Your Site Trial Documentation

Investigator site files are the backbone of trial documentation at the site level. Going digital by leveraging electronic site solutions such as the investigator site file, or eISF, should be a game changer. However, for many sites, sponsors, and CROs, that promise remains partially fulfilled.

Technology should increase efficiency and simplify workflows—not make them more complex. As solutions continue to advance, technology providers must work proactively to overcome lingering challenges in eISF adoption and better support inspection readiness, collaboration, and data integrity.

What’s Holding Them Back?

Despite advantages like improved access and reduced paper burden, many organizations still face issues which limit the value they get out of their eISF. Some of these issues include:

• Poor user experience: Overly complex interfaces, lagging performance, and disconnected systems cause more friction than efficiency.
• Incomplete compliance: Not all platforms are built with global regulatory requirements in mind. Missing features like audit trails, e-signatures, and version control can lead to findings during inspections.
• Limited training and engagement: Without structured onboarding and ongoing support, site teams may default back to familiar (but inefficient) paper processes.

These challenges create frustration, increase risk, and reduce data confidence. After all, nobody wants a delayed trial.

How to Get Strategic with Your eISF

To continue to drive technology adoption at the site level, it’s important to focus on smart enablement:

1. Build for Real-World Use

Modern eISF platforms must be fast, intuitive, and interoperable with existing CTMS and eTMF systems. The technology should fade into the background, enabling seamless site operations.

2. Bake in Compliance

Compliance shouldn't be an add-on. Features like real-time audit trails, role-based access, electronic signature support, and document versioning should come standard and be validation-ready for global regulatory environments.

3. Drive Engagement Through Enablement

Effective eISF adoption hinges on training and support. That means upfront enablement for study teams and site staff, along with refreshers and helpdesk access throughout the trial lifecycle.

4. Focus on Change Management

Rolling out a new system is as much about people as it is about technology. Capturing and communicating clear wins—like reduced monitoring queries or faster document turnaround—can help increase buy-in across stakeholders.

5. Track and Optimize

Post-deployment, organizations should continuously monitor usage metrics, document cycle times, and compliance indicators. These insights fuel ongoing improvements and ensure the eISF remains a flexible, high-value tool.
