There is overwhelming evidence that restricting patient access to new medicines and shifting drug costs to patients who cannot afford them has a negative impact on drug use compliance and thus a negative impact on both the quality of health outcomes and the cost of healthcare. A recently published study reveals that middle-aged and elderly patients who cut back on medication use because of cost were 50 percent more likely to suffer from a stroke or heart attack than those who did not report cost-related medication under-use. Improving drug use compliance is an important step in reducing unnecessary hospitalizations from adverse drug reactions but restricting access to needed medicines harms vulnerable patients, undermines the quality of care does nothing to improve drug use compliance.
