Assessment of a new calendar pack—the ‘C-Pak’

Seventy-eight elderly patients in hospital were studied for up to four weeks to assess drug compliance. Forty patients received medication from individualized calendar packs (‘C-Pak’) and 38 received medication from standard bottles. There was no difference in compliance between the two groups, the percentage error for each group being 26%. This result suggests that C-Pak is unlikely to improve drug compliance in unselected elderly patients.

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, over compliance, frequency of dosing interval, and living situation were also explored.

Unit dose calendar packaging and elderly patient compliance

A controlled trial of the effect of a unit dose system of tablet/capsule calendar packaging (Webster-Pak) on the rate of successful self medication both in hospital and after discharge to the community has been completed in a geriatric assessment and rehabilitation unit. Eighty-four elderly patients, 45 using calendar packs (study), and 39 using conventional bottles or packs (control), were followed for three months after discharge. There was a significant improvement in patient compliance in the study group over controls on discharge (86.7% vs 66.7%), 10 days (68.8% vs 41.0%), one month (64.4% vs 38.5%) and three months (48.9% vs 23.1%) after discharge. Unit dose packaging is a cost effective method of improving the delivery of medicine in elderly patients, and should be available as part of the health budget.
