Objective
The Patient Global Imression of Improvement (PGI-I) is a global index that may be used to rate the response of a condition to a therapy (transition scale). It is a simple, direct, easy to use scale that is intuitively understandable to clinicians.[1]
Intended Population
The PGI-I has only been tested on women with stress urinary incontinence. It has not been established to be applicable for men and women with other lower urinary tract symptoms or conditions.[1]
Method of Use
The PGI-I is a transition scale that is a single question asking the patient to rate their urinary tract condition now, as compared with how it was prior to before beginning treatment on a scale from 1. Very much better to 7. Very much worse.[1]

Reliability
Validity
The PGI-I was found to have excellent construct validity. The assessment variables included incontinence episode frequency, the Incontinence Quality of Life Questionnaire results, and fixed volume (400 mL) stress pad test results. The category differences for all variables was highly significant (P< .0001).[1]
Responsiveness
Miscellaneous
Global ratings can precise when used to assess the same person over time but they have a degress of imprecision across the spectrum of different people who might use it.[1]
