Evaluation of the Autohaler actuator: the effect of written patient instructions on correct use

J S Kelloway et al. J Asthma. 1993.

Abstract

The Autohaler actuator is a breath-actuated device designed by 3M Pharmaceuticals. The objective of this study was to measure and improve the effectiveness of the device's package insert instructions (PII). Using only the PII for guidance, 5 of 20 (25%) subjects failed to trigger the device. The PII were revised based on the subject's performance and suggestions. Using the revised PII, only 1 of 20 (5%) different subjects failed to trigger the device. These results indicate that relatively minor modifications to instructions can result in significant improvements in patient use. Eighty-five percent of the participants thought the device was easier to use than a metered-dose inhaler.
