Brief Summary:
The purpose of the study is to compare rates of cure of abscesses with and without antibiotic treatment after incision and drainage. The purpose of this study is to compare successful rates of cure of abscesses less than 5 cm with antibiotic (oral TMP/SMX) versus non-antibiotic treatment after incision and drainage.

Condition or disease Intervention/treatment Phase
Abscess Drug: oral trimethoprim/sulfamethoxazole Drug: Placebo Phase 3

Detailed Description:

This study is a randomized controlled trial of antibiotic treatment versus placebo after incision and drainage of skin and soft tissue abscesses less than 5 cm in pediatric patients. Eligible patients whose parents/guardians consented them to enrollment were randomized to receive one of two interventions: oral trimethoprim/sulfamethoxazole (TMP/SMX) or placebo after incision and drainage. Every attempt was made to make the placebo capsules and suspensions appear in all aspects like the true drug (was done by the investigational pharmacy department at our institution). Equal numbers of subjects were randomized at the outset to both study groups. Randomization, also done by our investigational pharmacy department, was done in blocks of 20. Patients were followed up in our emergency center at 24 to 48 hours to have any packing removed and to have their clinical/wound status assessed. They were not charged for this visit, and their valet parking was validated. If an individual patient, or an individual patient's wound, was felt to be not improving adequately, that patient was started on formal antibiotic therapy at the treating attending physician's discretion.

Primary outcome:

1. Abscess resolution by parental report 7-10 days after incision and drainage

Secondary outcomes:

  1. Admission to the hospital because of worsening infection
  2. Receipt of antibiotics (placebo arm) or change in antibiotics (antibiotic arm)

Arm Intervention/treatment
Active Comparator: oral trimethoprim/sulfamethoxazole
subjects with abscesses less than 5cm will be randomized to either study med or placebo
Drug: oral trimethoprim/sulfamethoxazole
80 mg caps or 8 mg/ml suspension every 12 hours for 10 days
Other Name: TMP/SMX

Placebo Comparator: placebo
Placebo after incision and drainage of abscess less than 5 cm.
Drug: Placebo
Placebo caps or suspension every 12 hours for 10 days
Other Name: Placebo caps




Primary Outcome Measures :
  1. Number of Participants With Abscess Resolution [ Time Frame: 10 days ]
    Outcomes will be measured by resolution of size, tenderness, and induration with erythema by parental report 7 - 10 days after initial visit to the Emergency Center


Secondary Outcome Measures :
  1. Number of Participants Requiring Admission for Failure of Abscess Resolution [ Time Frame: 10 days ]
    Percentage of patients requiring admission to Texas Children's or another hospital within 10 days of incision and drainage

  2. Number of Participants Requiring New or Modified Antibiotics for Failure of Abscess to Resolve [ Time Frame: 10 days ]

    For the antibiotic arm, we determined if the child was prescribed a different antibiotic.

    For the placebo arm, we determined if the child received a prescription for an antibiotic at a subsequent visit (e.g., in the emergency department, by their pediatrician, etc) within 10 days of incision and drainage
