Trial Outcomes & Findings for Effectiveness of Embrace Scar Therapy Device After Cutaneous Wound Closure (NCT NCT03294863)

NCT ID: NCT03294863

Last Updated: 2026-06-10

Results Overview

The Patient Observer Scar Assessment Score (POSAS) will be used to compare the cosmetic appearance of scars in the area treated with the device versus the area that was not treated. The POSAS measures scar quality in all types of scars by evaluating visual (e.g. color), tactile (e.g. pliability) and sensory (e.g. itch) characteristics of the scar from the perspective of the observer and patients. Scores for each subscale range from 1 to 10, for a sum score range from 6 to 60. Low scores indicate better outcomes.

Participant Flow

Participants recruited for the study had their scars divided into two sections, labeled A and B. These sections were randomized, with one section receiving standard care while the other received the study intervention. A total of 49 participants were included in the study, resulting in 98 wound halves assessed at baseline.

PRIMARY outcome

Timeframe: 3 months

Population: The study was terminated early due to inadequate participant follow-up during the COVID-19 pandemic, resulting in the analysis of only 20 participants. Each patient's wound was divided into two sides, labeled A and B. An intervention was randomly assigned to each side, leading to a total of 40 wound halves analyzed. However, due to the limited sample size, no conclusive results can be drawn.

The Patient Observer Scar Assessment Score (POSAS) will be used to compare the cosmetic appearance of scars in the area treated with the device versus the area that was not treated. The POSAS measures scar quality in all types of scars by evaluating visual (e.g. color), tactile (e.g. pliability) and sensory (e.g. itch) characteristics of the scar from the perspective of the observer and patients. Scores for each subscale range from 1 to 10, for a sum score range from 6 to 60. Low scores indicate better outcomes.

The data collection process for the study included a complication form designed to document all adverse events experienced by participants. The form required detailed information regarding the timing of the complications, the affected side, and any relevant contextual notes. Participants were invited to contact the research team at any time to report AEs. Furthermore, during the three-month follow-up, patients were asked about complication, and the reviewer noted any complications they observed.
