Checklists for powder inhaler technique: a review and recommendations

Area of Science:

• Respiratory Medicine
• Pharmaceutical Sciences

Background:

• Powder inhaler devices like Turbuhaler and Diskus are vital for respiratory disease management.
• Patient technique significantly impacts the effectiveness of these inhaler devices.
• Current assessment methods often rely on device-specific checklists, leading to variability.

Purpose of the Study:

• To review existing checklists and scoring systems for Turbuhaler and Diskus.
• To discuss the heterogeneity and limitations of current assessment tools.
• To recommend standardized checklists for improved research comparability.

Main Methods:

• Literature review of studies assessing Turbuhaler and Diskus technique.
• Analysis of common checklists and scoring systems used in research.
• Synthesis of findings to identify best practices and areas for standardization.

Main Results:

• Divergence in checklists and scoring systems hinders direct comparison of study results.
• Brief training based on checklists significantly improves asthma outcomes.
• Evidence on the relative importance of specific technique criteria is limited.

Conclusions:

• Standardization of checklists and scoring systems for Turbuhaler and Diskus is essential.
• Consistent assessment tools will enable accurate comparisons and meta-analyses.
• Adoption of recommended checklists can improve research reliability and patient care.
