FORMOSA NEWS

Postoperative surgical site infections remain a critical concern for global hospital safety and patient recovery. In a study published in 2026, Kusbaryanto, a medical researcher from Universitas Muhammadiyah Yogyakarta, investigated the prevalence and risk factors of Surgical Site Infection (SSI) among postoperative patients at PKU Muhammadiyah Gamping Hospital in Yogyakarta, Indonesia. Examining secondary medical record data from 150 patients, the investigation determined that 12.0% of surgical cases resulted in SSI. The findings highlight that pre-existing medical conditions, diabetes, long operating times, and extended hospital stays significantly increase infection risks, offering clear targets for hospital quality improvement.

Background and Clinical Context

Surgical site infections are among the most common healthcare-associated infections worldwide. The World Health Organization identifies SSI as a primary threat to patient safety, particularly in low- and middle-income nations where infection control infrastructure faces ongoing resource constraints. Beyond causing patient discomfort and delayed physical recovery, SSIs strain hospital operations by increasing readmission rates and inflating medical expenditures. Understanding context-specific infection drivers in regional healthcare centers like PKU Muhammadiyah Gamping Hospital is crucial for building effective, localized clinical protocols that safeguard surgical patients.

Research Methodology

The author conducted a quantitative observational study using a cross-sectional design based on secondary medical record data from PKU Muhammadiyah Gamping Hospital. A total sampling method was applied to gather data from 150 eligible postoperative patients.

  • Data Extracted: Patient age, sex, presence of diabetes mellitus, general comorbidities, duration of surgery, length of hospital stay, and wound cleanliness classification.
  • Analytical Framework: The researcher utilized univariate descriptive statistics to calculate overall prevalence, alongside Chi-square tests to evaluate bivariate associations between risk factors and SSI occurrences at a significance threshold of $p < 0.05$.

Key Findings

The overall prevalence rate of SSI stood at 12.0%, affecting 18 out of the 150 analyzed patients. Statistical analysis identified four primary factors directly linked to increased infection rates:

  • Length of Hospital Stay ($p = 0.001$): Patients hospitalized for more than five days represented 77.8% of all SSI cases, making extended hospital stays the strongest statistically associated factor.
  • Duration of Surgery ($p = 0.002$): Surgical procedures lasting longer than two hours accounted for 72.2% of post-surgical infections.
  • Underlying Comorbidities ($p = 0.009$): The presence of underlying medical conditions was observed in 66.7% of patients who developed SSIs.
  • Diabetes Mellitus ($p = 0.014$): Patients diagnosed with diabetes mellitus comprised 55.6% of the SSI group, compared to only 24.2% in the non-SSI group.

Demographic characteristics, including age ($p = 0.082$) and sex ($p = 0.562$), showed no statistically significant relationship with SSI occurrence. Similarly, wound classification types did not yield a statistically significant association ($p = 0.068$).

Real-World Impact and Practical Implications

The study's outcomes provide actionable insights for surgical teams, hospital administrators, and health policymakers working to refine infection control standards.

  • Preoperative Screening: Comprehensive evaluation and metabolic control for diabetic and comorbid patients prior to surgery can mitigate physiological vulnerabilities that hinder wound healing.
  • Surgical Efficiency: Streamlining operating room workflows to keep procedure durations under two hours minimizes the window for environmental microbial contamination.
  • Postoperative Management: Optimized discharge planning reduces unnecessary hospital days, protecting patients from extended exposure to hospital-acquired pathogens.

Academic Insight

In evaluating the clinical implications of the findings, Kusbaryanto from Universitas Muhammadiyah Yogyakarta noted:

"Both patient-related and procedure-related factors contribute to the occurrence of Surgical Site Infection among postoperative patients. Early identification and management of modifiable risk factors are essential to reduce SSI rates, improve patient safety, and enhance the quality of surgical care."
