Patient and Observer Scar Assessment Scale (POSAS)- Patient Scores 12M Primary · 12 Months

Validated scale used to assess the scar quality after surgery from patient and observer (clinician) prospective. Scoring: Each of the six items on both the Observer and Patient scales is scored on a 10-point numerical rating scale, where: 1 represents tissue that is like normal skin. 10 represents the worst scar imaginable for the observer, or the worst imaginable sensation/difference for the patient. The total score for each scale is the sum of the scores for the six items, ranging from 6 to 60. A higher score indicates a poorer scar quality while a lower scores indicates an ideal scar ou
