Antibiotic prophylaxis for dental procedures at risk of causing bacteremia among post-total joint arthroplasty patients: a survey of Canadian orthopaedic surgeons and dental surgeons.

To elicit current practice and attitudes toward use of antibiotic-prophylaxis among TJA patients prior to dental procedures, a cross-sectional survey of practicing Canadian orthopaedic (OS) and dental surgeons (DS) was undertaken. Of respondents, 77% of OS and 71% of DS routinely prescribe antibiotic-prophylaxis, but while 63% of OS advocate lifelong use, only 22% of DS choose to do so (P<0.0001). Both groups nonetheless recognize the importance of treatment within 2-years post-TJA as per AAOS/ADA guidelines. However, greater duration of practice pointed to potential inadequacy of these guidelines based on reported experience with late-hematogenous infection post-TJA. While discrepancies in attitude toward antibiotic-prophylaxis between surgeon groups remain, both groups agreed that the evidence to support decision making regarding antibiotic-prophylaxis for TJA patients undergoing dental procedures remains inadequate.
