Factors Associated With Surgical Site Infection Among Patients Undergone Abdominal Surgery in Northwestern Ethiopia: A Retrospective Cross‐Sectional Study

Abstract

Background and Aim: Among the myriad surgical procedures, abdominal surgeries stand out for their increased susceptibility to surgical site infections, owing to the intricate nature of the abdominal cavity. This study aimed to evaluate the prevalence and factors associated with surgical site infections among patients who underwent abdominal operations at Bichena Hospital. Methods: -value ≤ 0.05 was adopted to identify statistically significant factors influencing surgical site infection following open abdominal surgery. Results: The occurrence of surgical site infection was determined to be 26.8% (95% CI: 20.1%, 33.5%). Patients with concurrent medical conditions were over three times more likely (AOR = 3.37) to develop SSI compared to those without such conditions. Regarding hospital length of stay, patients with shorter stays had a significantly lower likelihood of developing SSI. Specifically, those with stays of 5-7 days had a 91% lower likelihood of SSI (AOR = 0.09), those with 8-14 days had a 78% lower likelihood (AOR = 0.22), and those with stays of 15-21 days had a 72.4% lower likelihood (AOR = 0.28), compared to patients with a hospital stay of 22 days or longer. The 22-day cutoff was determined based on the distribution of hospital stays within the study population, where longer stays beyond this period were associated with a higher incidence of infections. Conclusion: The study found a high incidence of SSIs at the institution. The presence of concurrent medical conditions and extended hospital stays was identified as a significant factor contributing to the occurrence of SSIs.
