Preoperative infection risk assessment in hip arthroplasty a matched-pair study of the reliability of 3 validated risk scales (original) (raw)

surgeons should carefully select patients before any joint reconstruction procedures to identify potential risks of PJI occurrence 4-7. In recent decades, the ASA (American Society of Anesthesiologists) Physical Status Classification System has commonly been used to assess a patient's pre-anesthesia medical comorbidities and, consequently, to assess the general complications risk in surgical procedures, without specifically addressing the risk of septic complications in orthopedic procedures 8,9. Over the last 30 years, many studies have specifically highlighted significant correlations between a patient's pre-operative pathological conditions and the occurrence of post-surgical infections, suggesting the need for appropriate scoring systems to precisely assess this risk. More recently, several pre-operative risk assessment scales, specifically designed to address PJI occurrence, have been proposed, but there is no general consensus on the most reliable one 10-16. At the time of this study, only three of these scales had been internationally validated: the more recent International
