Diabetic Retinopathy Clinical Trial
Official title:
Diabetic Retina Exam Rate Does Not Increase With Phone Reminders in Non-HMO Population
Diabetic retinopathy is the major cause of blindness in working age Americans, and screening
for it is cost-effective. There are a quarter of a million people in Southeast Michigan with
diabetes and pre-diabetes.
Only half of patients with diabetes are screened regularly for diabetic retinopathy, and
this proportion has been difficult to increase despite various interventions. Previous
research focused on HMO patient groups because preventative care was thought to decrease
plan costs. In addition, it was administratively feasible to track patient-doctor
interactions.
This project builds on published research and institutional experience to determine an
effective method for increasing the screening rate, in a mobile, non-HMO population. It uses
administrative methods and information technology infrastructures, such as large scale
electronic medical records and patient demographic databases, to identify existing patients
requiring examinations.
Patients were telephoned by a trained service representative who offered and scheduled firm
examination appointment times.
Hypothesis: Annual screening rates for diabetic retinopathy can be substantially improved in
non-HMO patient groups by directly contacting patients and scheduling firm appointment
times.
