Why this matters
Three different people may arrive at your site to look at your work, and they want different things. Treating all three the same wastes time and occasionally causes real harm.
This lesson separates them and tells you how to prepare.
Monitoring
Monitoring is the sponsor's routine oversight of trial conduct. E6(R3) section 3.11.4 describes it as one of the principal quality control activities, and requires it to be performed by people not involved in the clinical conduct of the trial at the site being monitored.
Two kinds:
- Site monitoring covers activities at the investigator site, including its pharmacy and local laboratories. It may be on site, remote, or both, and may include secure read-only remote access to source records.
- Centralized monitoring is the sponsor's evaluation of accumulated data by qualified staff such as a medical monitor, data scientist or biostatistician. It can complement site monitoring, reduce its extent or frequency, or be used on its own.
Your monitor typically checks consent, eligibility, protocol compliance, safety reporting, investigational product accountability, essential records and the site file, and compares reported data against source records.
One hundred percent source data verification is not required. Section 3.11.4.5.4(b) allows checking reported data against source records on the basis of samples, supported by data analytics as appropriate, and section 3.11.4.3 says the monitoring plan should focus on aspects critical to quality. If your monitor reviews a sample rather than everything, that is the guideline working as intended.
Types of visit. A site initiation visit before enrollment; interim monitoring visits during the study; a for-cause visit triggered by a specific concern; and a close-out visit at the end.
Working well with a monitor
- Prepare. Have the records they asked for ready. Have the participants' files organized. Book a room and make sure the investigator is available for the closing discussion.
- Answer honestly. Hiding a problem from a monitor delays its correction and destroys the trust that makes everything else easier.
- Discuss findings as they arise, not only at the end.
- Read the follow-up letter carefully. It lists actions, owners and dates. Put them in your calendar.
- Close actions and say when you have. The commonest complaint monitors have about sites is not errors; it is unresolved actions carried forward visit after visit.
Audits
An audit is a systematic and independent examination of trial-related activities and documents. It is not routine quality control; it tests whether the system works.
- Usually conducted by the sponsor's quality assurance function, or an independent group, and by people independent of the trial team.
- It looks at process as much as at data. Expect questions like "how does your site decide who may take consent?" and "show me the evidence".
- Under section 3.11.2.2(d), regulatory authorities should not routinely request audit reports. If an inspector does request one case by case, that decision belongs to the sponsor.
Inspections
An inspection is conducted by a regulatory authority. It carries legal force and can result in formal findings against the site or the investigator.
Preparing for one is not a special project. It is doing the ordinary work well, all the time. But there are behaviors worth learning now.
- Notify the sponsor immediately when an inspection is announced, or when an unannounced inspector arrives.
- The investigator hosts. They should be present or immediately available.
- Answer the question asked. Do not speculate. Do not volunteer material that was not requested.
- Say "I do not know, I will find out" when that is true. Guessing is far worse than not knowing.
- Never alter, create or back-date a document during or after an inspection. This turns a finding into misconduct.
- Keep a log of every document provided and every question asked.
- Have a scribe if you can, so that the person answering is not also taking notes.
The three compared
| Monitoring | Audit | Inspection | |
|---|---|---|---|
| Who | Sponsor or contract research organization | Sponsor quality assurance, or independent | Regulatory authority |
| Purpose | Routine quality control of this trial | Independent test of the system | Legal verification on behalf of the public |
| Frequency | Regular | Occasional | Rare |
| Result | Findings and actions | Audit report and corrective actions | Formal findings with legal consequences |
Corrective and preventive action
Where a significant or recurring problem is found, the site will be asked for a corrective and preventive action, usually shortened to CAPA.
- Correction fixes the specific instance.
- Corrective action addresses the cause so it does not recur.
- Preventive action addresses the same cause where it has not yet caused a problem.
A CAPA that says "staff were retrained" and nothing else is usually a weak CAPA, because training was rarely the whole cause. Ask what made the error easy to make.
In practice
Marcus's monitoring visit at Northside Clinic produces three findings. Two are minor filing issues. The third is that visit windows have been missed four times in three months, always for the month-four visit.
Nadia's first instinct is to apologize and promise to be careful. Instead she looks at the cause. The month-four visit is long and requires a fasting participant, and the clinic only offers afternoon slots for it.
The CAPA is not "retrain staff". It is: move fasting visits to the first morning slot, add a check of the visit window at the point of booking, and review upcoming windows weekly. She writes it down with dates and an owner.
Marcus verifies it at the next visit. The deviations have stopped.
Six months later a regulatory inspection reviews the same period. The deviations are still there in the record — nothing was hidden — alongside the analysis and the action taken. The inspector's comment is that the site identified and addressed the issue itself.
A finding you found, understood and fixed is a much smaller problem than a finding somebody else found.
Key takeaways
- Monitoring is routine sponsor quality control, performed by people not involved in the clinical conduct of the trial at that site, and may be on site, remote or centralized.
- One hundred percent source data verification is not required by E6(R3); section 3.11.4.5.4(b) allows sample-based checking supported by data analytics.
- An audit independently tests whether the site's system works, and under section 3.11.2.2(d) regulators should not routinely request audit reports.
- An inspection is conducted by a regulatory authority and carries legal force; notify the sponsor immediately, answer only what is asked, and never alter or create a document during one.
- A strong corrective and preventive action addresses the cause, and "staff were retrained" alone is rarely a sufficient explanation.
