What is the electronic Physician Global Assessment for Psoriasis?

The electronic Physician Global Assessment (PGA) is a 5- or sometimes 6-point scoring system used to assess the severity of Psoriasis. The terms physician or investigator global assessment may be used interchangeably. PGA is used as a global static assessment of all lesions and gives a general impression of the severity or improvement of psoriasis over time. The PGA was originally developed to collect the disease severity within clinical trials and is one of the standard parameters collected to assess the treatment success. In recent time, PGA is more commonly used in clinical practice to guide treatment decisions for physicians and document the impact of the clinical treatment over time. 

How to use the PGA for Psoriasis?

The PGA should only be used by trained physicians. The PGA score for psoriasis is measured by the number and severity of lesion induration, erythema and scale and ranges from from clear (0), almost clear (1), mild (2), moderate (3), to severe (4). Each severity grade is distinctly defined by a relevant morphologic description to ensure comparability of PGA scores between health care providers and over time.
