Brief Summary
The purpose of this study is to see if the use of a single-use negative pressure wound therapy system (NPWT) will have an effect on the reduction of post-surgical incision healing complications following breast reduction surgery and to assess the medium-term aesthetic appearance and quality of the resultant scar, compared with standard of care dressings.
Brief Title
PICO Breast Reduction Clinical Study Looking at Incision Healing Complications
Detailed Description
The aim of the present study is to assess the efficacy and cost-effectiveness of the Single-Use Negative Pressure Wound Therapy (NPWT) system (PICO) with regard to the reduction of postsurgical incision healing complications during the immediate postoperative treatment phase, and to assess the medium-term aesthetic appearance and quality of the resultant scar, in patients undergoing reduction mammoplasty, compared to standard care.

Official Title
A Prospective, Randomized, Intra-patient, Comparative, Open, Multi-centre Study to Evaluate the Efficacy of a Single-Use NPWT System on the Prevention of Incision Healing Complications in Patients Undergoing Reduction Mammoplasty
Primary Outcomes
Outcome Description
The primary variable of whether or not the incision developed a healing complication within 21 days of surgery was defined as the presence of at least one of the following:
1. Infection (superficial or deep),
2. Dehiscence (partial, superficial or deep),
3. Delayed healing (defined as incision not closed within 7 days of the first surgical procedure).
All participants received both PICO and standard care dressings simultaneously during the course of the study; randomized to either right breast for PICO and left breast for standard of care OR right breast standard of care and left breast PICO.
1. Infection (superficial or deep),
2. Dehiscence (partial, superficial or deep),
3. Delayed healing (defined as incision not closed within 7 days of the first surgical procedure).
All participants received both PICO and standard care dressings simultaneously during the course of the study; randomized to either right breast for PICO and left breast for standard of care OR right breast standard of care and left breast PICO.

Outcome Description
Assessment of the Patient and Observer Scar Assessment Scale (POSAS) and the Visual Analogue Scale (VAS) between postsurgical incisions treated with PICO compared with standard care dressings.
VAS score: Assessed for color, appearance, contour, distortion, and texture. Each score ranged from 5 to 18; 5 being 'excellent' and 18 being 'poor.' Also, a global scar score was included in the total score.
POSAS score: Scored in 2 parts which added to create a total score, observer score and patient score. The lowest score of 1 showed 'normal' skin and the highest score of 10 showed the 'worst imaginable' result.
Observer score = 6 categories (vascularity, pigmentation, thickness, relief, pliability, and surface area) each given a score of 1-10.
Patient score = 6 categories (scar pain, itching, color, stiffness, thickness, and irregularity each given a score of 1-10.
All participants received both PICO and standard care dressings simultaneously during the course of the study.
