What is the difference between POSAS 2.0 & 3.0?
The main reasons for the initiation of the project to develop the POSAS 3.0, was the lack of input by patients and international professionals in the development of the POSAS 2.0.
POSAS 3.0 measures scar quality in patients with all types of scars, including those caused by burns, necrotizing fasciitis, acne, trauma, or surgery. The Patient Scale has been developed using a series of focus group meetings that took place in the Netherlands and Australia. The Observer Scale has been developed using a systematic method to reach consensus among experts. The POSAS 3.0 contains more items to gain deeper insight in scar quality.
