OBJECTIVE: To determine whether an intervention at both the provider and
patient level can increase the utilization of diabetic retinal examination
among diabetic patients and to compare the results from a comparable study
conducted on the East Coast. RESEARCH DESIGN AND METHODS: For the regional
intervention study, all diabetic patients 18 years or older who enrolled in
a large network-based health maintenance organization (HMO) in California
were identified (n = 19,397). The identified diabetic patients received
educational materials and a notification of their prior diabetic retinal
examination status. Also, their primary care physicians received the
current American Diabetes Association (ADA) guidelines for dilated retinal
examinations and a list of patients due for diabetic retinal examination.
RESULTS: There were 25 and 27% increases in the percentage of diabetic
patients who received diabetic retinal examinations in 1995 compared with
the percentages in 1993 and 1994, respectively. The increase in diabetic
retinal examinations was most significant after the intervention (odds
ratio = 1.4). Furthermore, the improvements in compliance after the
intervention were almost identical between the studies implemented on the
East and West Coasts. CONCLUSIONS: This study and the prior study
demonstrate that such a "reminder" intervention can improve compliance with
diabetic retinal screening recommendations. A generalizable intervention,
such as this, may be applicable on a national level. For these programs to
be successful, however, HMOs and physicians must have a collaborative
relationship.
