PATIENT, PERIOPERATIVE AND HEALTHCARE SYSTEM RISK FACTORS FOR PROSTHETIC JOINT INFECTION FOLLOWING PRIMARY HIP ARTHROPLASTY: EVIDENCE FROM ENGLAND AND WALES

Introduction Prosthetic joint infection (PJI) is an uncommon but serious complication of hip replacement. A recent systematic review of patient risk factors for PJI identified male gender, smoking status, increasing BMI, steroid use, previous joint surgery and comorbidities of diabetes, rheumatoid arthritis and depression as risk factors for developing PJI. Limitations of the current literature include the short term follow up of most published studies. We investigated the role of patient, surgical and healthcare factors on the risk of revision of a primary hip replacement for PJI at different time-points in the post-operative follow-up. It is important that those risk factors are identified so that patients can be appropriately counselled according to their individual risk profile prior to surgery and modifiable factors can be addressed to reduce the risk of PJI at an individual and healthcare system level. Materials and Methods Primary hip replacements and subsequent revision procedures performed for PJ...
