Recruitment Status : Recruiting
First Posted : July 4, 2016
Last Update Posted : March 16, 2020
Information provided by (Responsible Party):
University of California, San Francisco

Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Cutaneous Abscess Procedure: Packing Other: No packing Not Applicable

Detailed Description:

Study protocol:

  1. Identification of a patient with a cutaneous abscess requiring incision and drainage
  2. Written consent obtained from the patient
  3. Study materials will be obtained

    • Enrolling physician fills out pre-procedure information (see data sheet)
    • Enrollment data sheet has instructions indicating whether patient is to receive packing or not

      • Use of random number generator to randomize all packets
    • Provider does abscess incision and drainage with or without packing according to the instructions
    • Enrolling physician fills out post-procedure information (see data sheet)
    • Patient returns within 48 hours for wound check with removal of packing if performed
    • Research coordinator or study physician calls the patient within 14 and 30 days after the procedure for follow-up

      • Information from a return visit and/or the telephone follow-up

Arm Intervention/treatment
Active Comparator: Packing
The patient is to have a long piece of gauze within the abscess cavity in an attempt to keep it open and allow purulent material to continue to drain after the initial incision and release of purulent material has been performed.
Procedure: Packing
The patient will receive packing as part of their wound care

Placebo Comparator: No packing
The patient is not to have packing of the abscess as part of the incision and drainage procedure
Other: No packing
The patient will not receive packing as part of their wound care

Primary Outcome Measures :
  1. Percentage of patients needing further treatment [ Time Frame: 14 days ]
    follow-up call to determine if patient required further treatment beyond routine care

Secondary Outcome Measures :
  1. Visual Analog Scale for Pain (VAS pain) post procedure [ Time Frame: 14 days ]
    Measure pain score after procedure
