What is Re-audit? A Practical Guide to Closing the Loop in Clinical Audit

Introduction

The initial phase of a clinical audit — often referred to as the 'first audit' or 'baseline audit' — helps us understand 'what is currently happening' in practice. Based on these findings, recommendations are made, and improvements are implemented. However, without a subsequent re-audit, we cannot confidently determine if the changes were effective or if the improvements have been maintained over time. Re-audit provides this essential feedback mechanism, transforming a snapshot assessment into a continuous loop of quality improvement.

Why this topic matters

Re-audit is fundamental to the principles of clinical governance and effective quality improvement within the NHS. It demonstrates accountability, provides assurance that patient care is consistently meeting standards, and ensures that the effort invested in the initial audit and change implementation yields tangible, sustained benefits. Without re-audit, there's a risk that improvements are transient, or that the initial audit merely highlights a problem without confirming its resolution.

For junior doctors and trainees, understanding re-audit is key to successfully completing audit projects, meeting curriculum requirements, and contributing meaningfully to their departments' quality agendas. For QI leads, it's about embedding a culture of continuous improvement and demonstrating real-world impact.

Practical explanation

Re-audit is essentially a repeat of a clinical audit, conducted after a period of time during which interventions or changes, based on the initial audit's recommendations, have been implemented. Its primary purpose is to assess if those interventions have led to the desired improvements and if the practice now meets the established standards.

Key elements of a re-audit:

• Timeliness: Re-audits should be conducted at an appropriate interval after the implementation of changes. This interval needs to be long enough for the changes to embed, but not so long that the data becomes irrelevant or the initial audit team has moved on.
• Comparability: The methodology (criteria, standards, data collection tools, sample size, and period) should ideally be identical or highly comparable to the initial audit. This allows for a robust comparison of results.
• Focus on Impact: The re-audit should specifically evaluate the effectiveness of the implemented changes. Did patient outcomes improve? Did adherence to guidelines increase? Were processes streamlined?
• Demonstrating Sustainability: Beyond initial improvement, re-audit can also help establish if changes are sustainable over a longer period.

Common pitfalls

Despite its importance, re-audits are often the most neglected part of the audit cycle. Common reasons include:

• Lack of dedicated resources: Time, personnel, and funding can be barriers.
• Staff turnover: The original audit team may have moved on, leading to a loss of corporate memory.
• Misunderstanding of purpose: Sometimes, teams may feel that simply implementing changes is enough, overlooking the need to verify their impact.
• Difficulty in demonstrating change: If the interventions were not clearly defined or if the initial audit had methodological flaws, proving improvement can be challenging.
• Poor communication: A lack of clear communication regarding the audit findings, recommendations, and planned interventions can hinder successful re-audit.

Step-by-step approach to conducting a re-audit

1. Review the Initial Audit and Recommendations

• Retrieve the original audit report: Understand the initial problem, criteria, standards, methodology, findings, and, crucially, the recommendations made.
• Identify implemented changes: Confirm which recommendations were acted upon and what specific changes were introduced into practice.
• Define the re-audit scope: Is the re-audit covering all the original criteria, or just those impacted by interventions? Usually, it's best to re-audit all original criteria for comparability.

2. Plan the Re-audit Methodology

• Maintain consistency: Use the exact same audit criteria, standards, data collection tool, sampling strategy, and data collection period as the original audit. This is paramount for valid comparison.
• Determine the interval: Choose an appropriate time frame since the implementation of changes. This might be 6-12 months, allowing changes to embed.
• Obtain approvals: Secure necessary approvals from your local clinical audit department and ensure data protection (GDPR/DPA) compliance.

3. Data Collection

• Collect data against the same criteria: Ensure the data collection is conducted in the same manner as the initial audit. Train new data collectors if necessary to minimise bias.
• Maintain data quality: Accuracy and completeness of data are essential.

4. Data Analysis and Comparison

• Analyse re-audit data: Calculate adherence rates, frequencies, or other relevant metrics for the re-audit period.
• Compare with baseline: Directly compare the re-audit results with the initial audit findings for each criterion.
• Statistical analysis (if appropriate): For larger datasets, consider simple statistical tests (e.g., chi-squared or t-tests, consulting with a statistician) to assess the significance of any observed differences. However, for most audits, clear graphical comparisons are often sufficient.

5. Reporting and Recommendations

• Produce a re-audit report: Clearly present the initial findings, the changes implemented, and the re-audit findings.
• Highlight improvement (or lack thereof): Clearly state where standards have been met, improved, or where further work is needed.
• Formulate new recommendations: If improvements are sustained, consider disseminating best practice. If not, critically analyse why, and develop new, specific, measurable, achievable, relevant, and time-bound (SMART) recommendations.
• Disseminate findings: Share the report with relevant stakeholders, including those involved in the initial audit, those who implemented changes, and relevant clinical governance committees.

Example in clinical practice

A multidisciplinary team on a surgical ward conducted an audit on compliance with the 'Venous Thromboembolism (VTE) Prophylaxis' NICE guideline. The initial audit showed 65% compliance. Recommendations included clearer documentation prompts in the electronic patient record (EPR), mandatory VTE risk assessment training for new staff, and regular senior clinician reminders at handover.

Re-audit conducted 9 months later:

• Methodology: Same audit tool, same data points (patient records), same patient cohort (post-operative patients), same data collection period (one month).
• Findings: Compliance with VTE prophylaxis had risen to 92%. The re-audit also noted improved documentation quality.
• Conclusion: The implemented changes were effective in improving VTE prophylaxis compliance. The findings were presented at the surgical governance meeting, shared with the training department, and the ward team was commended. The team decided to continue monitoring VTE compliance as part of routine governance and consider sharing their intervention strategy with other surgical units.

Conversely, if the re-audit showed only a marginal improvement or even a decline, the team would then need to re-evaluate their interventions, identify new barriers, and develop revised recommendations (e.g., redesign the EPR prompt, repeat training, escalate non-compliance).

How Lazomis can help

Lazomis offers tools that can significantly streamline the re-audit process, ensuring consistency and ease of comparison. Our QI Project Setup module allows you to store your initial audit methodology, criteria, and data collection tools, making it simple to retrieve and replicate for a re-audit. The Data Collection Templates can be reused for consistent data capture, and our Reporting Dashboards enable direct comparison of baseline and re-audit data, visualising changes over time with minimal effort. This centralisation helps overcome common pitfalls like staff turnover and inconsistent methodology, ensuring your re-audits are robust and impactful.
