The table shows the points for each of the 5 independent predictors (P: prior procedures; A: age; D: depressed estimated glomerular filtration rate; I: immunocompromised; and T: type of procedure).7,8 The risk score assigns weighted points based on characteristics of the procedure and the patient’s medical history (predictors) and determines the level of risk based on the total number of accumulated points, which categorizes patients into low (0–4), intermediate (5–6), and high (≥7) risk groups.
New pacemaker/ICD/CRT pacemaker or defibrillator or generator change; revision/upgrade includes pocket and/or lead revision and/or system upgrade, that is, with adding new lead(s).
Depressed renal function (estimated glomerular filtration rate <30 mL/min).
Receiving therapy that suppresses resistance to infection or has a disease that is sufficiently advanced to suppress resistance to infection.
Prior procedure(s) is inclusive of all procedures on the same pocket and including de novo implant.
CRT, cardiac resynchronization therapy; ICD, implantable cardioverter-defibrillator; PADIT, Prevention of Arrhythmia Device Infection Trial.
