"Of the thousands of medications available to older patients, a small group of blood thinners and diabetes medications caused a high proportion of emergency hospitalizations for adverse drug events among elderly Americans," said lead study author Dr. Daniel Budnitz, director of the U.S. Centers for Disease Control and Prevention's medication safety program (Goodwin, 11/25).

"We need to focus on those areas where we can have the greatest potential to reduce hospitalizations and health care costs," said [Budnitz]. ...
