Is routine antibiotic prophylaxis cost effective for total joint replacement patients?

J Arthroplasty. 2015 Apr;30(4):543-6. doi: 10.1016/j.arth.2014.11.001. Epub 2014 Nov 10.


The routine use of amoxicillin antibiotic prophylaxis prior to dental procedures for patients with total joint prostheses in place remains controversial. This analysis shows that the practice may not be cost-effective for patients in whom the risk of infection with dental work is low. However, specific data quantifying the risk and the impact prophylactic antibiotics can have is needed. Patients and physicians will need to continue to consider their use on an individual basis and should consider the risk of infection as well as the risk of adverse drug reaction when making treatment decisions.
