HIV pill reminder device shows some adherence improvement. Technology now switched to cell phone.

Researchers studying a population of HIV patients found that a pill reminder improved adherence for those who were memory impaired. "One reason patients don't take medications is because they simply forget it, and it's more of an issue in the population we studied because some started with mild cognitive impairment," says Adriana Andrade, MD, MPH, an assistant professor at Johns Hopkins University Division of Infectious Diseases in Baltimore, MD.
