So you thought I&Ding your abscess was enough? Or your attending told you….no cellulitis so no antibiotics? WRONG!
A recent double-blinded randomized-controlled trial of outpatient children and adults with abscesses <= 5cm who had I&D performed with either clindamycin or bactrim had higher cure rate at 7-10 days compared to the placebo group that had I&D but no antibiotics (NNT 8).
There was a difference in the Clindamycin and Bactrim group: new infection at one month was lower in the Clindamycin group but this group also had higher rate of diarrhea.
This only worked in patients that had a staph infection; but most >50% patients did have MRSA or MSSA.
This will definitely be changing my practice and I hope it helps all of you!
