ID-NP indicates ID without packing; ID-P, ID with packing; EP, expressed pus.
Overall improvement, fever, erythema, pain/tenderness, and drainage were assessed with a 5-point Likert scale: 0, never had symptoms; 1, much improved; 2, somewhat improved; 3, unchanged; 4, somewhat worse; 5, much worse.
Of the 9 patients whose condition had worsened at the 48-to-72–hour follow-up, only patient 170 had a wound-culture organism that was resistant to clindamycin (it was also D-test positive).
