Critical Appraisal of Research on Surgical Site Infections
This paper critically appraises three research studies examining surgical site infections (SSIs) — a preventable yet prevalent global health concern. Beginning with a quantitative cross-sectional study of nurses in Addis Ababa, Ethiopia, the paper examines compliance rates with evidence-based SSI prevention guidelines and demographic factors associated with greater adherence. It then reviews two qualitative studies — one using a phenomenological approach with operating room nurses in Sweden and another evaluating the Clean-Cut intervention in Ethiopia — to explore institutional, hierarchical, and resource-based barriers to compliance. Together, the studies illustrate why reducing SSIs requires not only education but also systemic, nurse-inclusive approaches to improving surgical safety culture.

What makes this paper effective
- The paper strategically pairs a quantitative study with two qualitative studies, demonstrating methodological awareness and showing how different research designs answer complementary questions about SSI compliance.
- It maintains a clear critical lens throughout — acknowledging the strengths and limitations of each study rather than simply summarizing findings, which elevates the appraisal beyond a literature summary.
- The conclusion synthesizes all three studies into a coherent argument: that reducing SSIs requires systemic, nurse-inclusive solutions rather than targeting individual provider behavior.
Key academic technique demonstrated
This paper demonstrates critical appraisal across multiple research methodologies. The author explicitly identifies what each study can and cannot tell us — for instance, noting that the quantitative study reveals compliance gaps but cannot explain why noncompliance occurs — and then uses the qualitative studies to fill that explanatory gap. This methodological triangulation is a hallmark of evidence-based practice writing in health sciences.
Structure breakdown
The paper opens with global epidemiological context before moving to a detailed appraisal of the quantitative study, then transitions into the rationale for qualitative approaches. The two qualitative studies are reviewed in sequence, with a brief comparison of their differing designs. The conclusion integrates all three studies into a practice-oriented recommendation. This funnel-then-synthesize structure is well-suited to evidence-based healthcare writing at the undergraduate level.
Introduction: The Global Burden of Surgical Site Infections
Surgical site infections (SSIs) are a serious source of concern worldwide. They are not only a health risk to patients but also pose a significant threat in terms of increasing antibiotic-resistant bacterial infections. Yet there remains a gap between theoretical knowledge of how to prevent such infections and how providers actually implement preventive measures. The issue of SSIs has been quantitatively identified as a serious problem — and is especially disheartening given that it is largely preventable: an estimated 60% of all SSIs are preventable if providers follow established guidelines (Mengesha et al., 2020).
This failure of compliance is not limited to underserved or low-resource medical systems. The prevalence of SSIs is approximately 19.6% in Europe, 20% in the United States, and in Africa ranges from as low as 12% in Algeria to as high as 31% in Nigeria (Mengesha et al., 2020). Within Ethiopia alone, infection rates across different regions vary widely, from 10.9% to 19.1% (Mengesha et al., 2020). In resource-poor countries, SSIs impose an even more considerable financial drain through unnecessary costs. There is also significant concern about the spread of antibiotic-resistant bacteria, with multidrug resistance as high as 82.9% in countries where antibiotic shortages are common and treatment options are limited (Mengesha et al., 2020). This paper reviews SSI prevalence quantitatively and then examines two qualitative studies that attempt to address the issue through meaningful, practitioner-centered approaches.
Quantitative Evidence: Nurse Compliance in Addis Ababa
In one study conducted by Mengesha et al. (2020) surveying nurses in Addis Ababa, Ethiopia, fewer than half of the 409 participants (48.9%) observed evidence-based guidelines to prevent SSIs. The study found that being male, having a higher level of education, and having more extensive work experience were all correlated with greater adherence to infection prevention guidelines (Mengesha et al., 2020). This suggested that raising educational standards for providers may result in lower infection rates. A 25-item list of best practices, scored on a 1–4 Likert scale, assessed compliance in a strictly quantitative fashion, spanning questions about handwashing, the use of preoperative shaving, and the appropriate use of antimicrobial agents (Mengesha et al., 2020).
Nurses were the focus of the study not to shift responsibility away from physicians, but because nurses typically play the most significant roles in pre- and postoperative patient care, and thus can have the greatest impact on care improvement. Proper implementation of surgical safety checklists by nurses has been linked to a reduced risk of infection, suggesting that hospitals can play a significant role in creating standard operating procedures that make compliance the default rather than something nurses must consciously strive to achieve.
The Role of Surgical Teams and Institutional Standards
The study authors also note the importance of the surgical team in creating an environment that reduces infection risk — including minimizing unnecessary personnel and conversations in the operating room, maintaining closed doors, ensuring appropriate ventilation, and adequately preparing both the patient and the hands of the surgical team (Mengesha et al., 2020). Compliance, in short, is a team effort.
The study offered useful insights and a perspective on Ethiopia in particular that was welcome given the relative lack of SSI research specific to that nation. However, one weakness of the study was that while it pointed to deficits in practice and, to a lesser extent, in knowledge and training, it did not solicit input from practitioners about why they did not comply. Providers are not necessarily willfully noncompliant, nor do they necessarily discount the importance of appropriate hygiene. Factors such as time pressure, lack of supplies, and perceived pressure from physicians or supervisors to rush may all contribute to incomplete adherence to surgical checklists. Because the study was quantitative in nature, providers had no opportunity to offer that kind of contextual input.
An important corrective, therefore, is to review qualitative studies alongside quantitative ones. While quantitative studies can confirm that practitioners are not always observing necessary procedures and can identify demographic correlates of compliance, qualitative studies allow providers to offer experiential input in an open-ended fashion.
