PASI Meaning and
Definition
-
PASI is an acronym for Psoriasis Area and Severity Index. It is a commonly used scoring system in the medical field to evaluate the severity of psoriasis, a chronic skin condition characterized by red, scaly patches on the skin. The PASI score is determined by assessing four key parameters: the extent of affected body surface area, redness (erythema), thickness (induration), and scaling of the lesions.
The PASI score ranges from 0 to 72, with higher scores indicating more severe symptoms. The severity of psoriasis can be classified as mild (PASI score of 0-10), moderate (PASI score of 10-20), severe (PASI score of 20-30), or very severe (PASI score of 30 or above). Health professionals use the PASI score to monitor disease progression, assess treatment efficacy, and compare the severity of psoriasis in different individuals.
Measuring the PASI score involves visual assessment and careful examination of the patient's skin lesions. Each assessed area (head, upper and lower extremities, trunk) is given a score based on the presence and intensity of the four parameters. The scores are then added up to calculate the final PASI score. This scoring system provides a standardized and objective method for evaluating the severity of psoriasis, enabling healthcare practitioners to make informed decisions regarding appropriate treatment options for patients.
