Analysis of Health System Size and Variability in Diabetic Eye Disease Screening in Wisconsin

Diabetic eye disease remains the leading cause of blindness in the US, largely because of low screening rates. Previous studies have tended to focus on patient-level factors associated with screening. Thus, interventions have emphasized patient education, yielding only modest improvements. In this study, HIP Investigators Dr. Meghan Brennan, Dr. Maureen Smith and Dr. Yao Liu used an all-payer, statewide claims database to assess screening variability across health systems and to determine whether a patient’s health system may be associated with screening receipt.

119 347 adults with diabetes from 698 primary care clinics in 143 Wisconsin health systems were included in this study. The results of this cohort study suggest that health system may be an important factor in diabetic eye disease screening receipt.
