Summary

Inhaled medications are the mainstay of the therapeutic management of respiratory disorders. Considered by many to be 'simple' and 'easy' to use, clinicians are aware that inhalers are often improperly used. However, there is no tool that can detect and record errors in either the timing or the method dose administration The investigators designed a device that makes an acoustic record each time an inhaler is used. Opening the device makes an acoustic file which is recorded, this file is "time-stamped" which means that the timing of drug administration is recorded. When the device is retrieved and acoustic analysis performed, the steps involved in using the inhaler can be determined. Hence, the subjects inhaler technique is assessed and errors in the inhaler use identified. Together this means that errors in inhaler technique and timing of use can be quantified. In this study the investigators attached the device to a discus dry powder inhaler. In order to eliminate the behavioral component of adherence and identify the mechanical issues associated with effective inhaler use the investigators studied subjects who were already in Hospital and already prescribed a discus inhaler. The investigators hypothesized that the device would identify which errors in technique were the most common and that this would provide insight into how these errors might be eliminated.

Conditions

• Asthma

Interventions

Type	Name	Description
BEHAVIORAL	Active Feedback	The inhaler will be fitted with a device that makes an audio recording of the inhaler use. This audio data will be downloaded to a computer program, analyzed for assessment of whether the steps involved in using the inhaler have been performed correctly. This information will be discussed with the patient.
