title: Assessment of a new calendar pack--the 'C-Pak'.
abstract: 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.
