Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patient and Observer Scar Assessment Scale (POSAS) scores | once every 3 months for 1 year after the last treatment | The observer scale of the POSAS consists of six items (vascularity, pigmentation, thickness, relief, pliability and surface area). All items are scored on a scale ranging from 1 ('like normal skin') to 10 ('worst scar imaginable'). The sum of the six items results in a total score of the POSAS observer scale. Categories boxes are added for each item. Furthermore, an overall opinion is scored on a scale ranging from 1 to 10. All parameters should preferably be compared to normal skin on a comparable anatomic location. comparable anatomic location. |
| Vancouver Scar Scale (VSS) scores | once every 3 months for 1 year after the last treatment | Physician evaluation comprised the use of the Vancouver Scar Scale (VSS) to evaluate the pigmentation (0=normal, 1=hypopigmented, 2=hyperpigmented), pliability (0=normal, 1= supple, 2=yielding, 3=firm, 4=banding, 5=contracture), height (0= flat, 1=5 mm), and vascularity (0=normal, 1=pink, 2=pink to red, 3=red, 4=red to purple, 5=purple). |
