Most Americans aren't healthy—and they aren't getting any better not following the advice of their primary care doctors.

According to a TeleVox Healthy World Report, "A Fragile Nation in Poor Health," three out of four Americans (83 percent) admit they don't follow treatment plans they've been given by their doctor exactly as prescribed. And health care professionals aren't quite as forgiving. They say 95 percent of patients fail to comply with treatment plans as prescribed.

According to the National Consumers League, nearly three in four Americans don't follow doctor's orders for taking prescription drugs, a problem associated with 125,000 patient deaths each year. One in three patients never even fills the prescription. Others forget to pick up their drugs from the pharmacy, skip doses, take their pills at the wrong time or take an incorrect dose.
