Orthopedic Surgical Site Infection Risk Score

Calculate orthopedic surgical site infection (SSI) risk from patient factors: BMI, diabetes, tobacco use, immunosuppression, malnutrition, prior SSI, and procedure type. Identifies candidates for preoperative optimization before elective arthroplasty.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate orthopedic surgical site infection (SSI) risk from patient factors: BMI, diabetes, tobacco use, immunosuppression, malnutrition, prior SSI, and procedure type. Identifies candidates for preoperative optimization before elective arthroplasty

Each component has a specific meaning:

  • Patient factors: BMI — The patient factors: bmi recorded for the scenario being assessed.
  • Diabetes — The diabetes recorded for the scenario being assessed.
  • Tobacco use — The tobacco use recorded for the scenario being assessed.
  • Immunosuppression — The immunosuppression recorded for the scenario being assessed.
  • Malnutrition — The malnutrition recorded for the scenario being assessed.
  • Prior SSI — The prior ssi recorded for the scenario being assessed.

Note: Interpret the ortho ssi risk score result against the thresholds and context described above.

How to Use

Enter the patient factors: BMI, diabetes, tobacco use, immunosuppression, malnutrition, prior SSI for the scenario you are assessing. Calculate orthopedic surgical site infection (SSI) risk from patient factors: BMI, diabetes, tobacco use, immunosuppression, malnutrition, prior SSI, and procedure type. Identifies candidates for preoperative optimization before elective arthroplasty. Use the ortho ssi risk score result to inform your calculation.
