Surgical Site Infection Clinical Practice Guideline Summary
This paper provides a critical summary of the National Collaborating Centre for Women's and Children's Health (NCC-WCH) clinical practice guideline on surgical site infection (SSI), published under the National Institute for Health and Clinical Excellence (NICE) in 2008 and reaffirmed in 2011. The summary examines the guideline's scope, stakeholder involvement, rigor of development, key recommendations, and implementation considerations. It covers pre-operative, intra-operative, and post-operative recommendations for preventing and managing SSIs, and evaluates the evidence-based methodology used to formulate those recommendations, including the use of systematic literature searches, an eight-level evidence hierarchy, and multidisciplinary expert consensus.
- Scope and Purpose: Guideline objectives, exclusions, and outcome measures
- Stakeholder Involvement: Development group composition and consensus methods
- Rigor of Development: Evidence hierarchy, search strategy, and synthesis methods
- Recommendations by Surgical Phase: Pre-, intra-, and post-operative SSI prevention recommendations
- Implementation Considerations: Barriers, costs, and indicators of guideline effectiveness

What makes this paper effective
- Closely follows the standard AGREE framework for appraising clinical practice guidelines, addressing scope, stakeholder involvement, rigor, recommendations, and implementation in a logical sequence.
- Clearly distinguishes between the three surgical phases (pre-operative, intra-operative, post-operative) when presenting recommendations, making the summary highly practical and easy to navigate.
- Acknowledges the limitations of the guideline, such as the exclusion of grey literature and potential conflicts of interest in stakeholder composition, demonstrating critical appraisal skills.
Key academic technique demonstrated
The paper demonstrates structured critical appraisal of a clinical practice guideline. Rather than simply restating the guideline's content, the author evaluates the methodology used to develop it — including the evidence hierarchy, stakeholder composition, and the basis for recommendations when evidence was absent — which reflects graduate-level health sciences analysis.
Structure breakdown
The paper opens with a full citation of the source guideline, then proceeds through five thematic sections: scope and purpose, stakeholder involvement, rigor of development, recommendations (organized by surgical phase), and implementation. This mirrors standard guideline appraisal frameworks and ensures comprehensive coverage of both content and methodology. The conclusion briefly addresses barriers to implementation, such as language differences and economic considerations.
Scope and Purpose
The scope and purpose of the clinical practice guideline entitled "Surgical Site Infection: Prevention and Treatment of Surgical Site Infection" is to provide guidance for surgical site infections (SSI). A surgical site infection is a wound infection that occurs following an invasive surgical procedure. The guideline does not address management of the operating theatre environment or related environmental factors, nor does it address prophylaxis and management of antibiotic-resistant bacteria. Anesthetic factors relating to SSI are also outside the guideline's scope.
The objectives of the guideline are to provide an approach to intervention and practice covering prevention, treatment, and management. Specifically, the guideline is intended to provide a structured approach to care with clear, consistent advice for caregivers and patients that addresses pre-operative procedures, the intraoperative phase, and post-operative procedures. The guideline considers the following outcome measures in its recommendations: (1) the incidence of surgical site infections; (2) wound healing time; (3) morbidity and mortality; and (4) cost-effectiveness, as measured by the cost per infection avoided and the cost per life saved each year.
Stakeholder Involvement
The methods used to formulate the guideline's recommendations included expert consensus and informal consensus. Registered stakeholder organizations were given the opportunity to comment on the scope of the guideline during early development and to comment on the evidence and recommendations during the concluding stage. The Guideline Development Group (GDG), a working group consisting of laypersons and professionals representing different areas of practice, developed the guideline. The GDG was convened by the National Collaborating Centre for Women's and Children's Health (NCC-WCH).
Membership in the stakeholder group included two surgeons, two microbiologists, a theatre nurse, a tissue viability nurse, an infection control specialist, a surveillance coordinator, and two patient/caregiver representatives. The inclusion of patient and caregiver representatives ensured that the target population was engaged in the document's development. In 2011, the NCC-WCH completed a review of this guideline and determined it to be current and correct as the most up-to-date version of the SSI guideline.
Possible conflicts of interest in the development of the guideline include the composition of the stakeholder group, which consists entirely of professionals engaged in some capacity with the pre-operative, intra-operative, and/or post-operative phases of surgical operations.
Rigor of Development
Clinical practice guidelines carry strong credibility when they are created by multidisciplinary teams of professionals and relevant stakeholders who may represent different clinical contexts. Data for the surgical site infection guideline was collected through hand-searches of published literature — both primary and secondary sources — and searches of electronic databases. Systematic searches were employed to answer the clinical questions formulated and posed by the GDG. Stakeholder organizations were invited to submit evidence to the GDG for consideration when it was relevant to the topic and scope and equivalent to or better than the evidence identified through systematic search strategies.
It is worth noting that grey literature was not part of the search strategy, and journals not indexed on the searched databases were not manually searched. An eight-level table of evidence types was employed to identify the level of evidence used in the guideline. These evidence types range from high-quality meta-analyses and systematic reviews of randomized controlled trials (RCTs), or RCTs with a very low risk of bias, to expert opinion and formal consensus. Qualitative studies in the form of case series and other non-analytic reports were also included. For each clinical question, the highest level of evidence available was selected for consideration.
The clinical evidence for individual studies was synthesized for evidence table input, and brief descriptions of each study were included in the guideline text. Both qualitative synthesis and quantitative synthesis (meta-analysis) were performed wherever sufficient research was identified to enable and merit these analyses.
