Cognitive factors and the use of over-the-counter medication organizers by arthritis patients

The present study investigated the ability of 45 arthritis patients, all using three or more prescription medications, to correctly load their medications into three types of over-the-counter medication organizers. The results indicated that use of a seven-day organizer with compartments for different times resulted in fewer errors than did an hour-by-hour wheel organizer or a seven-day organizer with only one compartment for each day. It was concluded that the seven-day organizer with compartments for different times appears to have the potential to improve compliance behaviors, but the usefulness of the other two organizers in promoting compliance is uncertain. Data analyses also indicated that age was not related to comprehension or loading accuracy of the organizers but that individuals using seven or more prescribed medications were particularly likely to make comprehension errors.
