Evaluation of a novel medication aid, the calendar blister-pak, and its effect on drug compliance in a geriatric outpatient clinic.

A prospective, controlled, crossover study on drug compliance was initiated in 22 elderly patients from a geriatric clinic. Half of the patients received their pills from a commercially prepared calendar mealtime blister-pak; the remaining patients received their medication from standard pill bottles. At the end of three months the two groups were crossed over. Pill count and issuance of a new drug supply were done monthly to assess compliance. It was found that the average noncompliance index was significantly decreased (9.17 to 2.04) with the blister-pak packaging system. The relationship of age, Folstein mini-mental status, overcompliance, frequency of dosing interval, and living situation were also explored.
