A Review of Electronic Devices to Assess Inhaler Technique

Abstract

Purpose of Review

Multiple electronic devices exist that provide feedback on the accuracy of patient inhaler technique. Our purpose is to describe the inhaler technique feedback provided by these devices, including specific technique steps measured, how feedback is displayed, target of feedback (patient, provider, researcher), and compatibility with inhaler type (metered-dose inhaler [MDI], diskus, etc.).

Recent Findings

We identified eight devices that provide feedback on inhaler technique. Only one device assessed all evidence-based MDI technique steps. Most devices provide limited real-time feedback to patients, if any feedback at all.

Summary

Technologies to assess inhaler technique are advancing and hold great potential for improving patient inhaler technique. Many devices are limited in their ability to detect all evidence-based technique steps and provide real-time user-friendly feedback to patients and providers. Usability tests with patients and providers could identify ways to improve these devices to improve their utility in clinical settings.
