Study summary

This prospective, randomized controlled trial enrolled a convenience sample of adults and children presenting to two Level 1 trauma centers over 12-months with subcutaneous skin abscesses necessitating drainage. Two methods of drainage were compared: 1) the LOOP technique or 2) standard packing technique.

Read the detailed description

This prospective, randomized controlled trial enrolled a convenience sample of adults and children presenting to two Level 1 trauma centers over 12-months with subcutaneous skin abscesses necessitating drainage. Patients were excluded if the abscess was on the hand, foot, or face or if it required admission or operative intervention. Patients were followed over 10 days to determine the primary outcome of treatment failure defined by need for admission, IV antibiotics, or repeat drainage within 10-day follow-up. The secondary outcomes included ease of procedure, ease of care, pain after insertion and patient satisfaction using a 10-point numeric rating.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2009 to primary completion in Nov 2012, 45 months.

Of 21 interventional studies with no phase under Abscess, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 56. This study's 45 months is above that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 12, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
