Types of Monitoring Visits


Pre-Study Visit

A pre-study visit takes place after a potential PI indicates interest in a specific clinical trial. The purpose of this visit is to determine the site’s ability to conduct the study. The CRA evaluates:

  • PI responsibilities and qualifications
  • Study objectives and procedures
  • Site facilities and equipment
  • Staff qualifications

Initiation Visit

Once the PI agrees to participate and all regulatory approvals are in place, an initiation visit verifies that the site understands:

  • Study overview and eligibility criteria
  • GCP guidelines and regulations
  • Data forms and recording
  • Regulatory documentation
Close-Out Visit

The final visit ensures proper completion of all study activities:

  • Complete outstanding data and queries
  • Return or destroy unused products
  • Final review of study documents
  • Record retention plans
  • Results notification plans
