HEDIS glaucoma compliance and reporting
HEDIS score of each health plan based on the percentage of plan participants over 65 years of age who have have one of the following evaluations over a 2-year period:
mid-level eye exam by a physician (level 2 - 4)
OR
glaucoma screening by a physician using the G code
OR
Visual field (perimetry) screening test

Glaucoma metrics: Can we improve HEDIS score?
HEDIS score – Impact
Improving HEDIS rates on average requires sustained, rational and often costly efforts – only 5% increase in breast cancer screening rates for the last 8 years (NCQA)
Low glaucoma rates can adversely impact total HEDIS score – an important surrogate for overall quality of care.

Glaucoma screening rates vary widely
Glaucoma screening rates vary from 22.8% to 93.3% among the managed care organizations1
Large differences between plans due to lack of standardized screening and disease management programs.
Underperforming plans will need to create in-house programs to improve rates. No programs for outsourced glaucoma screening and disease management.

Peristat Overview
WHY ONLINE PERIMETRY?
Benefits of Telemedicine Screening
SCALABILITY: Can be taken and delivered any time, any place, and to unlimited simultaneous users.
SELF-ADMINISTERED AND AUTOMATED: Online Perimetry is a SELF-test (unaided) – does not require a specialized technician to administer every test
COST SAVINGS: Online Perimetry requires no equipment and maintenance (Average perimetry device costs $15,000-20,000); Cost to administer a perimetry test - $60-100 per office test vs <$15 for Peristat
