Effectiveness of Interventions to Teach Metered-Dose and Diskus Inhaler Techniques. A Randomized Trial.

ABSTRACT:

Rationale

The most effective approach to teaching respiratory inhaler technique is unknown.

Objectives

To evaluate the relative effects of two different educational strategies (teach-to-goal instruction vs. brief verbal instruction) in adults hospitalized with asthma or chronic obstructive pulmonary disease.

Methods

We conducted a randomized clinical trial at two urban academic hospitals. Participants received teach-to-goal or brief instruction in the hospital and were followed for 90 days after discharge. Inhaler technique was assessed using standardized checklists; misuse was defined as 75% steps or less correct (≤9 of 12 steps). The primary outcome was metered-dose inhaler misuse 30 days postdischarge. Secondary outcomes included Diskus technique; acute care events
