Common Findings from Internal Audits and Their Root Causes

Key Findings from Internal Clinical Audits and How to Address Their Root Causes

Why Identifying Common Findings Matters in Clinical QA

Internal audits serve as a powerful quality tool in clinical research. They help detect early warning signs of non-compliance, assess site preparedness, and prevent repeat observations during sponsor or regulatory inspections. By analyzing the most common findings—and more importantly, their root causes—QA teams can implement proactive measures and improve system-wide performance.

Findings from internal audits are typically categorized as Minor, Major, or Critical depending on their impact on subject safety, data integrity, or regulatory compliance. However, without investigating the “why” behind these issues, corrective actions often remain superficial.

For instance, repeated late SAE reports across multiple audits may stem not from staff negligence, but from poorly written SOPs that fail to specify exact timelines. Root cause analysis (RCA) helps shift focus from symptom correction to system correction, aligning with the principles of ICH E6(R2).

Most Frequent Internal Audit Findings Across Sites

Based on trend analysis across multiple clinical sites and therapeutic areas, the following findings are most frequently observed:

✅ Use of outdated informed consent forms
✅ Incomplete or missing delegation of duties logs
✅ Protocol deviations not reported or poorly documented
✅ Missing source documentation or unverified data
✅ Delays in SAE reporting
✅ Gaps in IP accountability logs or temperature records
✅ CVs or GCP training certificates expired or absent

Let’s explore a few of these in detail with corresponding root causes.

Case Study 1: Outdated Informed Consent Forms

Finding: Subject 1102 was consented using version 1.2 of the ICF, while version 1.3 had already been approved by the IEC two weeks prior.

Risk: This constitutes a GCP violation and may compromise subject rights and regulatory acceptability.

Root Causes:

✅ Lack of ICF version control procedure at site
✅ No centralized ICF version tracker in the ISF
✅ Training not updated after protocol amendment

Recommended CAPA: Implement a controlled ICF issuance log, revise SOPs to include version management, and train all staff within 48 hours of any ICF revision notification.

Case Study 2: Protocol Deviations Unreported

Finding: Multiple subjects missed their Day 28 follow-up visits due to holidays, but these were not logged as protocol deviations.

Risk: Impacts data consistency and breaches the predefined visit window.

Root Causes:

✅ Site staff unclear on what constitutes a deviation
✅ Absence of protocol deviation tracking log
✅ Infrequent CRA visits or data verification

Recommended CAPA: Develop deviation definitions guide, use a deviation capture template, and conduct refresher training on protocol timelines.

Case Study 3: Missing Signatures on Delegation Logs

Finding: The sub-investigator was delegated IP management duties but had not signed the delegation log.

Risk: Violates GCP accountability standards and invalidates related entries in the IP logbook.

Root Causes:

✅ Delegation logs not updated in real time
✅ PI oversight lacking in supervision of staff additions
✅ Poor handover documentation during staff transitions

Recommended CAPA: Enforce mandatory weekly PI reviews, digitize delegation logs with access restrictions, and create SOPs for onboarding documentation.

Case Study 4: IP Temperature Excursions Not Reported

Finding: The temperature logs showed excursions beyond +8°C for 4 hours, but no deviation or impact assessment was documented.

Risk: May compromise drug integrity and violate sponsor storage conditions.

Root Causes:

✅ Site staff unaware of excursion thresholds
✅ Lack of 24/7 temperature monitoring alerts
✅ No predefined excursion response plan

Recommended CAPA: Upgrade to digital data loggers with alarms, introduce a temperature deviation SOP, and conduct IP handling training for all new staff.

Data Trending and Heatmap Tools for Audit Findings

To gain insights into repeat findings, QA teams should trend audit data across multiple sites or studies. Use tools like:

✅ Heatmaps – to visualize high-risk categories (e.g., Consent vs Safety)
✅ Pareto Charts – to identify top 20% findings causing 80% issues
✅ RCA Dashboards – linking root causes to SOPs and functions

Below is an example heatmap from 10 recent audits:

Audit Category	Finding Frequency	Risk Severity
Informed Consent	8/10 audits	High
IP Accountability	5/10 audits	Medium
SAE Reporting	6/10 audits	High
CVs & GCP Certificates	7/10 audits	Low

Data-driven decision-making ensures that limited QA resources are directed to the most impactful areas.

Conclusion

Understanding common internal audit findings and digging into their root causes enables QA teams to go beyond checklists and drive meaningful compliance improvements. By trending issues, standardizing CAPA, and integrating lessons into SOP revisions and training, clinical organizations can elevate their inspection readiness and quality culture. Remember, each finding is an opportunity for system strengthening—not just correction.

Interviewing Site Staff During Internal Audits

Interviewing Site Staff During Internal Audits

How to Interview Site Staff Effectively During Internal Clinical Audits

Why Interviewing Site Staff is a Crucial Audit Activity

Interviewing site staff is a key component of any internal clinical trial audit. While document review and physical inspection provide hard evidence, staff interviews reveal how well trial operations are understood and followed in practice. These interviews can uncover training gaps, process deviations, or areas where SOPs are misunderstood or inconsistently applied.

Internal QA audits are meant to be educational and proactive. Interviews provide an opportunity to assess GCP understanding, site procedures, and staff engagement. For example, if a sub-investigator cannot clearly describe SAE reporting timelines, it may indicate a need for retraining. Conversely, confident, accurate responses demonstrate a site’s state of readiness.

Regulators like the FDA often conduct similar interviews during inspections. Training site staff to handle internal interviews with clarity and confidence sets the foundation for successful external audits.

Preparing for the Interview Component of the Audit

Preparation starts well before the actual interview. QA auditors should review the following before interacting with site personnel:

✅ Delegation of duties log – to verify who performed key tasks
✅ Site training records – to assess who was trained and when
✅ Protocol and ICF versions – to tailor interview questions
✅ Prior monitoring reports – to identify trends or prior findings

Identify target interviewees based on their roles. Common staff to include:

✅ Principal Investigator (PI)
✅ Site Coordinator / Study Nurse
✅ Pharmacist / IP Manager
✅ Lab / Sample Processing Staff

Prepare open-ended, non-leading questions that probe understanding. For instance: “How do you ensure that the correct ICF version is used before enrollment?” instead of “Did you use the current ICF version?”

Setting the Tone: Conducting Interviews with Professionalism

Interviewing site staff during internal audits requires both technical knowledge and soft skills. The objective is not to intimidate or corner the staff but to assess processes and identify improvement areas. Use the following techniques:

✅ Start with an introduction: explain the purpose of the interview and build rapport
✅ Keep a conversational tone: allow staff to speak freely
✅ Take notes discreetly and repeat key points for clarity
✅ Avoid judgmental or accusatory language
✅ Encourage staff to reference documents when unsure

For example, during a GCP internal audit at a diabetes study site, the QA auditor asked the coordinator, “How do you manage missed visits?” The coordinator outlined their process and then showed the subject tracking log, reinforcing their answer with documentation. This interaction added credibility to their process and confirmed compliance.

Sample Interview Questions by Role

Here’s a quick overview of sample questions categorized by staff role:

Role	Sample Questions
Principal Investigator	– How do you oversee protocol adherence? – How are SAEs reported and reviewed? – How often do you review site delegation?
Site Coordinator	– What steps do you follow before subject enrollment? – How do you ensure ICF version control? – How are data queries resolved?
Pharmacist / IP Manager	– How is IP temperature monitored? – Describe the IP reconciliation process. – How do you handle IP returns or destruction?

Documenting Responses and Linking to Audit Observations

QA auditors should document interview responses in real-time or immediately after. It’s important to:

✅ Use direct quotes for key statements
✅ Note any inconsistencies with SOPs or protocols
✅ Categorize responses (Compliant, Incomplete, Requires Follow-up)
✅ Cross-check answers with delegation logs and training records

All documented findings must be objective and linked to the applicable regulations. For example, if a nurse states that verbal consent was obtained before the written form, this could be flagged under ICH E6(R2) noncompliance and require corrective action.

Tools like interview summary templates and response forms (found on PharmaValidation.in) can standardize data capture and enhance audit traceability.

Handling Challenging Situations During Interviews

Not all interviews go smoothly. Auditors must be prepared to handle situations such as:

✅ Staff showing signs of nervousness or confusion
✅ Incomplete or contradictory responses
✅ Lack of awareness about critical procedures

In such cases, strategies include:

✅ Allowing staff to refer to SOPs or logs to clarify
✅ Rephrasing the question in simpler terms
✅ Gently steering the discussion back on track
✅ Offering to revisit the question later

Never escalate or create a confrontational atmosphere. Internal audits are opportunities for quality improvement—not punitive assessments.

Post-Interview Debrief and Feedback Loop

After completing all staff interviews, QA auditors should summarize their impressions in the audit report. The post-interview debrief must include:

✅ General staff understanding of GCP principles
✅ Any training gaps or process inconsistencies observed
✅ Recommended actions (training, SOP revision, CAPA)

If major issues are uncovered, an immediate verbal summary may be shared with site leadership during the audit closing meeting. Detailed writeups follow in the formal audit report, with timelines for CAPA responses.

All staff feedback collected during the audit can also be anonymized and used for site-wide process improvement or future training planning.

Conclusion

Interviewing site staff during internal QA audits is an invaluable tool for assessing real-world compliance and operational knowledge. A well-conducted interview helps uncover silent gaps, fosters better understanding of SOPs, and prepares teams for external scrutiny. By preparing structured questions, maintaining a respectful tone, and documenting findings objectively, QA auditors can make this process insightful and impactful for clinical trial success.
