A new study from the Annals of Internal Medicine says cheaper drugs would help reduce the problem of people not actually taking - or refilling - prescription medicine that would treat chronic conditions and avoid more acute and expensive problems.
The study suggested that various forms of intervention and coordination have varying results.

The Annals of Internal Medicine is a publication of the American College of Physicians.
The study concluded that, "Reduced out-of-pocket expenses, case management, and patient education with behavioral support all improved medication adherence for more than one condition. Evidence is limited on whether these approaches are broadly applicable or affect long-term medication adherence and health outcomes."
