Rationale for Teaching Patients About Surgical Site Infection Risk Factors
Patient education about surgical site infection (SSI) risk factors is essential because SSIs are the most common and most preventable hospital-acquired infection, and informed patients can actively participate in modifiable risk reduction strategies that directly impact morbidity, mortality, and healthcare costs. 1
Why Patient Education Matters
Impact on Clinical Outcomes
SSIs result in increased morbidity, disability, prolonged hospital stays, mortality, and significantly increased costs (ranging from $1,300-$30,000 per infection depending on severity). 1
One in four patients develop postoperative complications within 14 days of hospital discharge, making post-discharge patient vigilance critical. 1
SSIs are an independent risk factor for developing incisional hernias and lead to re-operations, increased post-surgical pain, poor wound healing, and decreased quality of life. 1
Empowering Patient Participation
Risk factors operate at three distinct levels: patient-level (modifiable and non-modifiable), operative/surgical procedure-related, and institutional/hospital-related. 1
Patients can directly influence several modifiable risk factors through education, including smoking cessation, nutritional optimization, glucose control in diabetes, and proper wound care adherence. 1
Specific Risk Factors Patients Should Understand
Patient-Level Risk Factors (What Patients Can Influence)
Age, comorbidities (especially diabetes mellitus), smoking habit, obesity, malnutrition, immunosuppression, and malignancies all increase SSI risk. 1, 2
Diabetes mellitus has the strongest evidence as an independent risk factor for increased SSI rates. 3
Preoperative hospitalization longer than 3 days and postoperative hospitalization longer than 7 days are associated with higher infection rates. 4
Procedure-Related Factors (What Patients Should Monitor)
Emergency surgery carries higher SSI risk due to contaminated/dirty wounds, prolonged operation duration, and higher patient acuity. 1
Wound contamination class, duration of operative procedure, and abdominal operations specifically increase susceptibility. 2, 5
Educational Content for Optimal Outcomes
Preoperative Counseling
Early evaluation of perioperative SSI risk factors and patient risk stratification assists in clinical decision-making and helps patients understand their individual risk profile. 1
Patients should understand that optimizing perioperative conditions can decrease infection risk, even when many risk factors are beyond control. 1
Postoperative Wound Care Instructions
Surgical wound dressings should remain undisturbed for a minimum of 48 hours after surgery unless leakage occurs. 1
Patients need to recognize early signs of infection and understand when to seek medical attention, as complications often manifest after discharge. 1
Implementation Strategy
Active Education Techniques
Academic detailing, consensus building sessions, and educational workshops should be implemented rather than passive information delivery. 1
Education must translate into behavior change, as knowledge alone may not modify deeply established patient behaviors without proper motivation and understanding. 1
Addressing the Evidence Gap
There is considerable variability in surgical wound care practice, reflecting overuse of ineffective care, underuse of effective care, or uncertainty about appropriate care. 1
Patient education helps bridge this gap by ensuring patients understand evidence-based practices versus marketing-driven wound care products without strong supporting evidence. 1
Critical Caveats
No single risk stratification strategy is superior for all patients, so education must be individualized to the patient's specific risk profile and surgical procedure. 1
While immunosuppression is clinically considered a risk factor, the evidence is mixed, so patients on immunosuppressive therapy should receive heightened surveillance rather than definitive warnings. 3
Patients should understand that SSI rates range from 1.9% to 40% depending on the type of surgery, providing realistic expectations without causing undue anxiety. 1
