Surgical Site Infection Clinical Trial
Official title:
Multiple Doses Versus Single Dose of Cefazolin to Prevent Periprosthetic Joint Infection After Revision Arthroplasty: a Multicenter Open-label, Randomized Clinical Trial.
The goal of this randomized control trial is to investigate the superiority of 5 days (extended) versus a single dose of cefazolin prophylaxis in revision arthroplasty of the hip and knee. The main question[s] it aims to answer are: - Is an extended regimen compared to a single dose of cefazolin associated with an increased infection-free implant survival within one year after index revision arthroplasty of the hip or knee? - What are the incidence, risk factors, treatment outcome and prognosis of surgical site infections and periprosthetic joint infection during follow-up? - What is the safety and tolerance of the antimicrobial prophylaxis regimens used? - What are the antimicrobial susceptibility patterns of micro-organisms causing PJI during follow-up? - What is the patient' physical performance and satisfaction of subjects within 1 year after the index revision arthroplasty, using patient related outcome measurements (PROMS)? [question 2] Participants will [describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items]. If there is a comparison group: Researchers will compare [insert groups] to see if [insert effects].
Periprosthetic joint infection (PJI) is an important complication of total joint arthroplasty of the hip and knee and occurs in 1-2% after primary arthroplasty and in 10-15% after revision arthroplasty. To prevent a PJI, peri-operative antibiotic prophylaxis is given. There's inadequate evidence for a recommendation about the optimal duration of prophylaxis, especially in revision arthroplasty. The aim of this multicenter open-label, randomized controlled trial is to investigate the superiority of 5 days (extended) versus a single dose of cefazolin prophylaxis in revision arthroplasty of the hip and knee. Patients will be recruited at the orthopedic departments of two Dutch hospitals, University Medical Center Radboudumc Nijmegen (Radboudumc) and Sint Maartenskliniek in Nijmegen (SMK). Patients will be included if they will undergo revision arthroplasty of the hip or knee, with exclusion of patients with a proven PJI at baseline. A total of 780 subjects will be randomized between 2 prophylactic strategies: A) Cefazolin at a single dose of 2 grams intravenously 15-60 minutes before incision; B) Cefazolin at a dose of 2 grams intravenously 15-60 minutes before incision, followed by cefazolin 1 gram intravenously t.i.d. until five days post-surgery. The primary endpoint is the difference in proportion of infectious-free implant survival between both groups within 1 year of follow-up. ;
