The goal of this study is to examine patients undergoing incision and drainage of cutaneous abscesses to determine if routine packing of the abscess cavity affects the need for further interventions such as repeat incision and drainage, antibiotic administration or hospital admission.

Official Title

Is Routine Packing of Cutaneous Abscesses Necessary?


Study protocol:

  1. Identification of a patient with a cutaneous abscess requiring incision and drainage
  2. Written consent obtained from the patient
