Planning a Multi-Site Clinical Audit: A Practical Guide for UK NHS Teams

Why this topic matters

Multi-site clinical audits are increasingly important for understanding the consistency and quality of care delivered across different organisational settings within the NHS. They can highlight unwarranted variation, identify best practices, and provide a more powerful evidence base for change than single-site studies. For example, a multi-site audit of a specific surgical complication rate or the management of a common condition can reveal whether local protocols are effective or if there are systemic issues requiring national attention.

For trainees, leading or participating in a multi-site audit provides invaluable experience in project management, collaboration, data handling, and presenting findings, all crucial for professional development and demonstrating competence in QI. For clinical leads and audit departments, these projects contribute significantly to organisational learning, CQC compliance evidence, and driving sustained improvements in patient care.

Practical explanation

A multi-site audit involves collecting data on the same clinical process or outcome across two or more separate healthcare organisations or departments. The core principles of audit remain: defining a standard, measuring performance against it, identifying gaps, and implementing changes. However, the 'multi-site' aspect necessitates additional considerations:

• Clear Scope and Objectives: A well-defined, focused question is paramount. Multi-site audits can quickly become unwieldy if the scope is too broad.
• Standardisation: Ensuring that the audit criteria, data collection methods, and data definitions are consistently applied across all sites is critical to ensure comparability of data.
• Governance and Approvals: Each participating site will have its own clinical audit and information governance (IG) processes that must be navigated.
• Collaboration and Communication: Effective communication between sites, often involving a lead site and participating sites, is essential for success.
• Data Management: Secure and consistent data collection, storage, and analysis methods are required to maintain data integrity and comply with IG.

Common pitfalls

Awareness of potential challenges can help in proactive planning:

• Lack of standardised methodology: Different interpretations of audit criteria or data collection methods can render data incomparable.
• Governance delays: Underestimating the time and effort required to gain approval from multiple audit and IG departments.
• Poor communication: Inconsistent communication can lead to misunderstandings, missed deadlines, and disengagement from participating sites.
• Data inconsistencies: Errors in data entry, missing data fields, or differing definitions across sites can significantly impact data quality.
• Over-ambition: Attempting to audit too many variables or too many sites without adequate resources.
• Lack of buy-in: Not securing engagement from key clinicians and management at each participating site from the outset.
• Ethical and IG breaches: Inadequate anonymisation or inappropriate sharing of patient-identifiable data.

Step-by-step approach to planning a multi-site audit

Step 1: Define the Audit Question and Standards

Start with a clear, focused audit question. What specific aspect of care are you examining? What outcome are you hoping to influence? Identify relevant national, professional, or local standards against which you will audit. Prioritise standards from sources such as NICE, Royal Colleges, or specialist societies. For example, "Is the documentation of VTE risk assessment in elective orthopaedic patients compliant with Trust guidelines (based on NICE NG89) across three regional hospitals?"

Step 2: Establish the Core Team and Identify Participating Sites

Form a small 'steering group' or 'lead team' that will oversee the project. This team should ideally include a senior clinician to provide leadership and mentorship, a dedicated project lead (often a trainee), and potentially representation from audit or QI departments. Identify potential participating sites and informally gauge their interest. Collaboration often works best with existing networks or colleagues known to the lead team.

Step 3: Develop a Robust Protocol

This is the cornerstone of a successful multi-site audit. The protocol must be comprehensive and unambiguous, covering:

• Audit objectives and specific questions.
• Patient inclusion/exclusion criteria: Be very precise.
• Audit criteria/standards: What exactly are you measuring against? How will compliance be defined?
• Data items to be collected: List every data point specifically. Consider if existing digital systems can support automated extraction or if manual chart review is needed.
• Definitions: Provide clear, unequivocal definitions for all data items (e.g., 'What constitutes a 'complete' VTE assessment?').
• Method of data collection: Will it be manual chart review, database extraction, or a combination? Who will collect it? How will inter-rater reliability be ensured if multiple people are collecting data?
• Sample size and sampling strategy: How many patients per site? Will it be consecutive patients, random sampling over a period, or a fixed number?
• Roles and responsibilities: Clearly outline who is responsible for what at each site.
• Communication plan: How will the lead site communicate with participating sites?
• Timeline: Realistic dates for all stages.
• Analysis plan: How will the data be analysed? What statistical methods may be used?

Step 4: Navigate Governance and Approvals

This is often the most time-consuming step. Each participating NHS organisation will require formal approval. This usually involves submitting your detailed protocol to their local clinical audit department and information governance (IG) team.

• Clinical Audit Approval: The clinical audit department will review your protocol against national audit standards and local policies. They ensure it's a valid audit and not research (which has a different approval pathway).
• Information Governance (IG) Approval: The IG team will assess how patient data will be accessed, stored, anonymised, and shared. They ensure compliance with GDPR, the Data Protection Act 2018, and local IG policies. Often, a Data Sharing Agreement (DSA) is required between sites if patient-identifiable data (even pseudonymised data) is transferred. Emphasise anonymisation as early as possible.
• Ethics: Most multi-site audits will fall under 'service evaluation' or 'audit' and will not require R&D or ethics committee approval, as they measure current practice against a standard. However, it is crucial to get institutional confirmation from each audit department as to whether your project is indeed audit/service evaluation and not research. Do not assume.

Step 5: Pilot and Refine Data Collection Tools

Before launching fully, pilot your data collection tool at one or two sites. This will uncover ambiguities, identify logistical issues, and help refine definitions. A standardised data collection form or electronic system (e.g., a secure online REDCap database, or a simple anonymised spreadsheet on a secure NHS system) is essential.

Step 6: Data Collection and Ongoing Communication

Once approvals are in place and tools are refined, commence data collection. Maintain regular communication with all sites, providing updates, offering support, and addressing any queries promptly. A central point of contact is vital.

Step 7: Analysis and Dissemination

• Analyse the pooled data: Compare performance across sites (anonymised, e.g., 'Site A', 'Site B') to identify variations and highlight areas of good practice or areas for improvement.
• Report findings locally and centrally: Share results with participating sites, their audit/management teams, and present findings regionally or nationally where appropriate. Ensure each site receives its own anonymised results so they can implement local QI initiatives.

Example in clinical practice

A group of surgical trainees, supported by a consultant, decided to conduct a multi-site audit on the adherence to enhanced recovery after surgery (ERAS) protocols for elective colorectal surgery across three NHS trusts in their region. They established a clear protocol based on published ERAS guidelines from professional bodies.

Each trainee took responsibility for gaining local audit and IG approval at their respective trusts. They developed a standardised data collection form, piloted it, and then collected data retrospectively for 100 consecutive patients at each site. All data was entered into a secure, anonymised online database approved by all IG departments.

The audit revealed significant variation in compliance with specific ERAS elements (e.g., timing of fluid administration, early mobilisation, cessation of nasogastric tubes) across the trusts. Site A demonstrated higher adherence and better patient outcomes (shorter length of hospital stay without increased complication rates). The audit findings were presented at regional meetings and local departmental meetings, leading to shared learning and the adoption of best practices from Site A across the other trusts, demonstrating the power of a multi-site approach to drive tangible improvements in patient care.
