A multiple-indication review conducted by the CLAHRC WM Director showed that prophylactic antibiotics effectively reduced post-operative infections, with an effect size in relative risk ratio terms that was independent of the type of surgery. A recent paper  confirmed that prophylaxis also reduced risk of infection after acute stroke. However, it did not improve functional outcomes, length of stay, or mortality, and the authors do not recommend routine use.
