Brief Summary:
The incidence of skin and soft tissue infections has increased dramatically over the last decade, in part due to increased prevalence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA). Incision and drainage (I&D) is considered the primary intervention, however some clinicians prefer ultrasound guided needle aspiration (US Asp). The investigators performed a randomized trial comparing US Asp to I&D for uncomplicated skin and soft tissue abscesses, with a subgroup analysis of patients with CA-MRSA.

Arm Intervention/treatment
Active Comparator: Incision and Drainage
Abscess underwent incision and drainage
Procedure: Incision and Drainage
Surgical incision of the skin surface followed by expression of purulence with or without debridement or manual exploration of abscess cavity.

Active Comparator: Ultrasound guided needle aspiration
Ultrasound was used to identify the abscess location. A needle was introduced into the abscess cavity and aspiration of the contents were attempted.
Procedure: Ultrasound Guided Aspiration
Ultrasound is used to identify the abscess cavity. An 18 gauge needle is introduced into the abscess cavity and manual aspiration of the abscess contents is attempted.

Primary Outcome Measures :
  1. Successful drainage of abscess [ Time Frame: 7 days ]
    Clinical outcome at 7 days

Secondary Outcome Measures :
  1. Successful drainage of abscess [ Time Frame: 2 days ]
    Healing of abscess following drainage procedure at day 2

  2. Ability to evacuate purulence from abscess [ Time Frame: Day 1 ]
    Amount of purulence produced by drainage procedure on day 1
