Objective: This study aimed to evaluate the impacts of deep surgical site infections (dSSIs) regarding hospital readmissions, prolonged length of stay (LoS), and estimated costs. Patients and Methods: We designed and applied a matched case-control observational study using the electronic health records at the University Medical Center Groningen in the Netherlands. We compared patients with dSSI and non-SSI, matched on the basis of having similar procedures. A prevailing topology of surgeries categorized as clean, clean-contaminated, contaminated, and dirty was applied. Results: Out of a total of 12,285 patients, 393 dSSI were identified as cases, and 2864 patients without SSIs were selected as controls. A total of 343 dSSI patients (87%) and 2307 (81%) controls required hospital readmissions. The median LoS was 7 days ([P.sub.25]-[P.sub.75]: 2.5-14.5) for dSSI patients and 5 days ([P.sub.25]-[P.sub.75]: 1-9) for controls (p-value: Conclusion: dSSI is associated with increased costs, prolonged LoS, and increased read-mission rates. Elevated risks were seen for elderly patients and those with neoplasms. Additionally, a protective effect of prophylactic antibiotics was found.

Introduction Surgical site infections (SSIs) present a high risk of prolonged lengths of stay (LoS) and readmissions. (1-5) In the United States, SSIs reportedly occurred in 1.9% of surgical procedures. [...]
