Cost-Effectiveness of Behavior Activation Versus Supportive Therapy on Adherence to Eye Exams in Older African Americans With Diabetes.

Although the importance of ophthalmologic screening in diabetic patients is widely recognized by clinicians, the cost-effectiveness of strategies aimed at improving eye care utilization in this population is not well established. A cost-effectiveness analysis was performed comparing behavior activation (BA) to supportive therapy (ST) in activating patients to receive a dilated fundus exam (DFE) and promoting healthy management of diabetes. Two hundred six subjects were randomized to receive either BA or ST between 2009 and 2013. Cost-effectiveness was calculated as incremental cost-effectiveness ratio (ICER) of BA versus ST. Total costs for BA and ST per participant were $259.02 and $216.12, respectively. At the 6-month follow-up, 87.91% of BA subjects received a DFE compared to 34.48% of ST subjects. The ICER for BA versus ST was $80.29/percent increase in DFE rate. In terms of improving DFE rates, BA was found to be more cost-effective than ST.
