How to Review Site Infrastructure and Equipment During Clinical Trial Feasibility

Site infrastructure and equipment play a pivotal role in the feasibility and operational success of a clinical trial. Even the most qualified investigators cannot compensate for inadequacies in physical infrastructure, diagnostic tools, or investigational product (IP) storage conditions. This guide provides a structured approach to reviewing site infrastructure and equipment during the feasibility phase to ensure regulatory compliance and protocol readiness.

Why Infrastructure and Equipment Assessment Matters

A site’s ability to manage study procedures, patient safety, and data integrity depends heavily on its infrastructure. Failure to verify the presence and functionality of essential equipment during feasibility can result in:

• Protocol deviations
• Delayed subject enrollment or visit execution
• Compromised sample quality
• Regulatory findings during inspections

Key Areas to Assess During Feasibility

1. Investigational Product (IP) Storage

• Secure, access-controlled storage areas
• Refrigerators and freezers with temperature monitoring and alarm systems
• Backup power systems in case of outages
• Separate storage for controlled substances

2. Clinical Laboratory Capabilities

• On-site sample processing capabilities (centrifuge, dry ice, etc.)
• Availability of a certified lab or partnership with external accredited labs
• Sample storage (frozen, ambient, refrigerated) with labeling compliance
• Logistics support for sample shipment per StabilityStudies.in standards

3. Diagnostic and Imaging Facilities

• Access to equipment required by protocol (e.g., ECG, X-ray, MRI, spirometer)
• Maintenance and calibration logs for equipment
• Qualified staff to operate diagnostic tools

4. Clinical Space and Accessibility

• Private examination rooms for subject visits
• Waiting area and consultation space
• Easy accessibility for patients with disabilities
• Dedicated room for monitoring visits (CRA workspace)

5. Data Entry and Technology Infrastructure

• Reliable internet connectivity for EDC systems
• Computers or tablets for eCRF entry
• Access to printers and document scanning tools
• Secure data backup and user access control measures

Feasibility Questionnaire Inclusions

Ensure your feasibility form includes questions on:

• Availability of each piece of equipment listed in the protocol
• Make, model, and last calibration date
• Contingency plans for equipment failure
• Site SOPs for equipment maintenance
• Ability to store and ship biospecimens

Site Tour and Visual Inspection (Virtual or On-site)

Whether conducted virtually or in-person, a site tour offers critical insight:

• Verify storage areas match questionnaire responses
• Photographic or video evidence of equipment setup
• Check expiry dates on IP supplies and calibration certificates
• Evaluate workflow and subject flow through clinical space

Using an Equipment and Infrastructure Checklist

Create a standardized checklist aligned with protocol needs, covering:

• Refrigerated storage (2°C to 8°C)
• Freezer storage (−20°C or −70°C if required)
• Blood pressure monitor, weighing scale, thermometer, etc.
• ECG machine and defibrillator (for certain studies)
• Emergency equipment and SOPs for medical incidents

Templates from Pharma SOPs can support documentation and standardization.

Red Flags to Watch For

• Shared IP storage without restricted access
• No documentation for equipment calibration
• Over-reliance on external labs without proper agreements
• Lack of training records for diagnostic tools
• Improper waste disposal or sample handling SOPs

Integration into Site Scoring and Selection

Assign scores to each infrastructure component using a weighted matrix:

• IP storage readiness (30%)
• Lab and diagnostic capability (25%)
• Data infrastructure (20%)
• Clinical space and accessibility (15%)
• Contingency systems and SOP adherence (10%)

This score feeds into the final site selection decision along with investigator experience and patient pool potential.

Regulatory Guidance

ICH-GCP E6(R2) requires that trial sites be “adequately equipped” to conduct the protocol and handle trial-related emergencies. Agencies like the USFDA and CDSCO expect documentation of infrastructure assessment to be maintained in the Trial Master File (TMF).

Conclusion

Site infrastructure and equipment evaluation is a non-negotiable element of feasibility assessments. A well-documented, checklist-driven review ensures site readiness, regulatory compliance, and study success. Whether evaluating storage conditions or lab capabilities, attention to operational details prevents future deviations and supports high-quality clinical data.
