Surgical Site Infections (SSI) Understanding and Treatment Algorithm

Surgical Site Infections (SSI) Overview and Diagnosis

SSI are infections that occur at or near a surgical incision within 30 days of a procedure, or within one year if an implant is placed. SSI is among the most common healthcare-associated infections and can involve the skin, subcutaneous tissue, deep soft tissues, organs, or surgical spaces. Common causative pathogens include staphylococcus aureus, coagulase-negative staphylococci, enterococcus species, and gram-negative bacteria. SSI can lead to prolonged hospitalization, increased healthcare costs, reoperations, and higher morbidity and mortality.

The diagnosis of SSI is primarily based on clinical evaluation. Common signs and symptoms include redness, swelling, warmth, pain or tenderness at the surgical site, purulent drainage, wound dehiscence, and fever. Microbiological cultures obtained from wound exudates or tissue samples help identify the causative pathogen and guide antimicrobial therapy. Imaging modalities such as ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI) may be utilized when deep incisional or organ/space infections are suspected.

Current Surgical Site Infections (SSI) Treatment Landscape

Treatment of SSI depends on the severity and extent of infection. Mild superficial infections may be managed with wound care and targeted antibiotic therapy, whereas deep or organ/space infections often require surgical drainage, debridement, or additional operative intervention. Empiric antibiotic therapy is typically initiated based on the likely pathogens and later adjusted according to culture results. Preventive strategies, including perioperative antibiotic prophylaxis, nasal decolonization, proper skin antisepsis, and emerging technologies such as localized antimicrobial delivery and photodisinfection therapies, play a critical role in reducing SSI incidence and improving surgical outcomes.
