Medication organization devices provide compartments to help sort patients' medications by days of the week and are thought to improve medication safety. Assessing patients age 75 and older who were prescribed three or more oral medications, this feasibility study found that medication adherence did not improve among those given medication organization devices compared to those using standard medication dispensing. The authors note that many potentially eligible participants were excluded because they already used such devices and suggest that future studies target a younger age range.
