What is it about?

The impact of blister packaging in the outpatient setting is unclear, and the types of patients who use them is not well-defined. This study demonstrated an improvement in adherence after implementation of a blister pack in a small group of patients who were mostly female, elderly, cognitively impaired, and had a high pill burden.

Why is it important?

It is often assumed that blister packaging medication will lead to improved medication adherence; however, it is important to measure adherence in patients receiving this type of packaging and their characteristics to see what types of patients may benefit most from a blister pack.


This study did demonstrate a significant improvement in adherence but any generalizations should be extremely cautious. It was a small number of patients and their unique characteristics must be considered when applying these results to any other patient.
