A new study released by the Partnership to Fight Chronic Disease finds that passing along rebates on prescription diabetes medicines at the pharmacy counter, could save individuals with diabetes $3.7 billion annually. Sharing rebates also would reduce overall health care spending by improving medication adherence and reducing diabetes-related complications.d adherence could also mean one million fewer hospital visits annually. PFCD Chairman Dr Ken Thorpe of Nevada says sharing rebates directly with the consumer would more positively effect patients, and minimize the economic impacts of this disease resulting from preventable complications, disability and medical utilization.
