This study has been completed.
Information provided by:
Baylor College of Medicine Identifier:
First received: December 28, 2007
Last updated: December 2, 2010
Last verified: December 2010
The purpose of this study is to compare successful rates of cure of abscesses less than 5 cm with antibiotic versus non-antibiotic treatment after incision and drainage. We will also compare successful rates of cure and time to healing with IV antibiotics and 23-hour observation unit stay versus hospitalization with IV antibiotics for abscesses greater than 5 cm but less than 10 cm in pediatric patients.

Condition Intervention Phase
Drug: oral trimethoprim/sulfamethoxazole
Drug: Placebo
Other: Observational Unit Short Stay
Other: Hospitalization
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Phase 3 Study Comparing Bactrim to Placebo in the Management of Abscesses < 5cm and 23 hr Observation Unit to Inpatient Treatment in the Management of Abscesses 5-10cm in the Pediatric Population.

Further study details as provided by Baylor College of Medicine:

Primary Outcome Measures:
  • Proportion of patients having abscess resolution to those that do not for each of the treatment modalities employed. For the < 5 cm arm, compare the proportions of patients with successful outcomes between the placebo and TMP/SMX groups. [ Time Frame: 3yrs ]

Secondary Outcome Measures:
  • The 5 - 10 cm arm, will compare the proportions of patients with successful outcomes between the 23-hour observation and hospitalization groups. [ Time Frame: 3yrs ]

Estimated Enrollment: 472
Study Start Date: December 2007
Study Completion Date: April 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
