LEARNING OBJECTIVES

• 1.Define clinical audit and differentiate it from clinical research and quality improvement projects
• 2.Describe the key steps of the clinical audit cycle
• 3.Explain the role of clinical audit in improving patient safety

INTRODUCTION

Clinical audits have a structured approach that involves measuring current practices, comparing them with standards, and addressing identified gaps.[1–3] The focus of the clinical audit is to answer a simple question: are patients receiving care that is consistent with best-practice standards to achieve better outcomes? The purpose is not to place blame but to identify areas for improvement and implement measures to enhance effectiveness, safety, and outcomes.[4] The impact of a clinical audit is evident across numerous healthcare disciplines.[5] Clinical audit directly supports patient safety programs and regulatory requirements, including accreditation standards that require routine review and improvement of clinical care.

Clinical research studies, quality improvement projects, and clinical audits may all aim to advance healthcare quality, but they differ in their purposes and approaches, as shown in Table 1.[6]

THE CLINICAL AUDIT CYCLE

The clinical audit cycle consists of steps, ranging from identifying the problem to sustaining improvements and conducting the reaudit (Fig. 1). This is a cyclical process that is structured and transforms into safer, effective care for the patients.[7,8] To make these steps more concrete, the steps are linked to a hypothetical case study.

Figure 1.

Five steps of the clinical audit cycle.

Step 1: Identifying the Problem

The clinical audit topic should have clinical importance and impact on patient care, such as high-risk or poor patient outcomes. It must be aligned with scientific evidence, guidelines, or systematic reviews. The clinical audit topic must be chosen using a strategic, risk-aligned approach that employs an explicit criterion to prioritize the topic. Once the topic is chosen by the organization, one can define the audit’s purpose and select a suitable audit method and, as a team, ask what the benefit to patients will be from this audit. Involving the entire team or participants in the identified problem to be audited helps ensure that it is relevant and supported. Topics are usually selected based on the level of risk, alignment with organizational priorities, patient safety incidents, new practices, or regulatory requirements. In this way, topics such as infection control practices, treatment adherence, surgical safety checklists, improvements in chronic disease management, or any other topic related to better patient outcomes and improved quality of care[9] can make a real difference.

Case study

The orthopedics department staff notices that several patients have developed postoperative infections after major surgeries. A quick review of cases suggests that antibiotic prophylaxis was not always given at the recommended time before incision. Because postoperative infections are directly linked to patient safety, prolonged hospital stay, and higher costs, the department decides to conduct a clinical audit on the timing of prophylactic antibiotics.

Step 2: Defining the Standards

Once the problem is identified, the next step is to define the standards by which the current practices will be measured. These standards are the benchmarks for comparison. Defining standards is an essential part of the clinical audit process because the current practice is measured against these agreed standards. When determining the standards for clinical audit, it is essential to consider the clinical importance of the outcome, practicability, and acceptability.[10] The standards can be derived from reliable sources such as the National Institute for Health and Care Excellence (NICE) guidelines, the World Health Organization (WHO), the Agency for Healthcare Research and Quality (AHRQ), international accreditation bodies, national standard-setting bodies, or clinical practice societies. The main outcome of this step is a well-defined standard for comparing current practices and identifying gaps in care.

Case study

The orthopedics team adopts the following standard from an accepted perioperative guideline: all patients undergoing orthopedic procedures should receive a prophylactic antibiotic within 60 minutes before surgical incision. The target compliance is 100%. This statement is clearly written in the audit protocol to avoid ambiguity later during data collection or analysis.

Step 3: Data Collection

In this step, the audit team prepares a clinical audit tool, which may be paper-based or electronic, as per the hospital’s convenience. Explicit instruction should specify what information needs to be captured, including exact times, procedures, and/or outcomes. For example, the time frame may be defined as the last 3 months of cases, and data collection can be retrospective or prospective.[11] The data can be collected by the audit team or any staff member assigned. A representative sample size is sufficient rather than a large one because the emphasis in auditing is on descriptive rather than inferential analyses. The data should be relevant, accurate, complete, accessible, and confidential. The data are compared against the agreed standards. After that, the data will be analyzed using quantitative or qualitative analysis, as appropriate.

Case study

The clinical audit team reviews 30 consecutive medical records of patients who underwent orthopedic surgery procedures over the last 3 months using the clinical audit tool. For every patient, the time of antibiotic administration and the time of surgical incision are recorded. The audit team found that only 60% of patients received the prophylactic antibiotic within 60 minutes of the incision. The remaining patients received antibiotics after surgery had already started. This clearly shows a gap between current practice and the standard.

Step 4: Making Improvements

In this step, the audit team will discuss the findings from data analysis with the multidisciplinary clinical team and other relevant stakeholders. Together, develop a practical action plan to address the gaps identified. The action plan should specify who will do what, by when, and how changes will be monitored. Possible changes include updating the clinical protocol, providing staff training, altering the workflow, creating a new strategy, and revising the existing pattern. Where appropriate, a structured approach such as the hierarchy of interventions, starting with system-level changes before relying on individual training, can help prioritize the most effective improvements. The main outcome of this step is an agreed-upon, actionable plan that addresses the gaps in current practices.

Case study

Based on the clinical audit results, the department of orthopedics introduces a mandatory pre-incision checklist in the operating theatre that includes a specific item on antibiotic prophylaxis. The circulating nurse in the operating room must confirm that the correct antibiotic has been administered within 60 minutes before incision and document this on the checklist. The clinical protocol is updated accordingly, and brief training sessions are held with the surgeons and theatre staff.

Step 5: Sustaining Improvements

After implementing the action plan, sufficient time should be allowed for changes to become embedded into routine practice, typically 3 to 12 months.[12] The audit team then conducts a reaudit (closing the loop) using the same standards and methods to measure whether the improvements have been achieved and sustained.[13] If the reaudit confirms that the standard is now consistently met, the new practice may be incorporated into clinical protocols or training. The same topic or a related one with expanded scope should be revisited periodically to ensure standards are maintained and/or to drive further improvement. If the improvement is not confirmed, the audit team conducts further analysis, refines the plan, and repeats the audit cycle. The goal of this step is sustained, measured improvement in clinical practice that benefits patients.

Case study

After implementing the mandatory pre-incision checklist, the orthopedic department allows 6 months for the process to be fully integrated into routine practice. A reaudit was conducted on a sample of 30 surgical cases using the same standard and method. The findings demonstrated significant improvement in compliance with the checklist protocol. Based on these results, the pre-incision checklist was incorporated into the operating theatre protocols with defined team roles and ensured the timely availability of prophylactic antibiotics to sustain adherence.

SUMMARY

By aligning with evidence-based standards, the clinical audit process supports consistency of care, standard treatment across teams, risk reduction, resource management, and clinical governance. In healthcare organizations, regular clinical audits encourage a culture of learning and continuous improvement, which enhances patient safety goals and ensures that patients receive consistent, high-quality treatment.
