How monitoring, audit and inspection differ in a clinical trial

Monitoring follows trial conduct; an audit independently examines defined processes and records; an inspection is a regulatory review. Their purposes differ. A company's name in an audit history does not establish a partnership or endorsement.

The word “review” can describe several activities. For a useful sponsor or CRO discussion, clarify the purpose, reviewers and access boundaries first.

Three different purposes

Activity Main purpose Who performs it
Monitoring Oversight of trial progress and conduct Specialists appointed by the sponsor under a monitoring plan
Audit Independent examination of selected processes and records Auditors independent of the activity being audited
Inspection An official regulatory review An authorised regulatory authority

This short explanation follows ICH E6(R3), section 3.11 and the glossary. It uses an international reference; determine the applicable procedure for the jurisdiction and study concerned.

What to agree before a visit

A practical discussion list, rather than a description of reviews carried out at Bessalar:

  • Purpose and scope: site selection, a particular protocol or a specific process?
  • Records: which list, period and document versions are needed?
  • People: who demonstrates the process, answers questions and records agreements?
  • Access and confidentiality: where can records be reviewed, and how is unnecessary disclosure of personal information avoided?
  • Follow-up: how will findings be presented, and who discusses responses and subsequent actions?

Do not send source medical records through the general website form. Agree document access separately.

Reading a review history

Instead of a row of logos, request information that may be disclosed: review type, date, scope and supporting evidence. A review having taken place and specific findings having been closed are different facts. Historical evidence does not establish that processes remain unchanged today.

Publishing another organisation’s name or logo also requires a separate check of the basis for doing so. This article does not announce clinic partners, audit outcomes or inspection results.

Next step

Read about the quality system and site selection questions. In an enquiry to the clinic, describe the purpose of the proposed visit and document scope. Agree arrangements before sharing materials.

Questions and answers

Does a sponsor audit replace a regulatory inspection?

No. Audits and regulatory inspections differ in authority, purpose and personnel. An audit alone does not authorise a new study or establish that a site can deliver every protocol.

Does an audit establish a partnership?

No. A separate basis and permission to disclose the relationship are needed. Naming an auditor or the organisation commissioning a review is not, by itself, a recommendation of the clinic.
