Antibiotic prophylaxis for total joint replacement surgery: results of a survey of Canadian orthopedic surgeons.

<bold>Background: </bold>The role of perioperative antibiotic prophylaxis in total joint replacement (TJR) surgery is well established. Whereas guidelines have been published in some countries, in Canada controversy persists concerning the best clinical practice for perioperative antibiotic prophylaxis in TJR.<bold>Methods: </bold>We conducted a survey of 590 practising orthopedic surgeons performing TJR in Canada to assess current antibiotic prophylaxis practice. The survey included questions pertaining to antibiotic prophylaxis indications, antibiotic choice, dosing, route and timing of administration in the primary and revision arthroplasty setting, as well as postoperative wound drainage evaluation and management.<bold>Results: </bold>The response rate after 2 mail-outs was 410 of 590 (69.5%). Current antibiotic prophylaxis regimens varied widely among surgeons, underscoring the controversy that exists regarding what constitutes best clinical practice.<bold>Conclusion: </bold>Opinions regarding use of perioperative antibiotic prophylaxis in TJR vary widely among orthopedic surgeons in Canada, illustrating the controversy as to what constitutes best clinical practice. This survey also points to a lack of consensus about the current management of postoperative wound drainage. [ABSTRACT FROM AUTHOR]
