Abstract: Poor inhaler technique has been shown to be associated with less asthma control and increased health care utilization. Little is known about the impact of inhaler technique on the most vulnerable patients.This study examined inhaler technique in low-income, inner-city adults with uncontrolled asthma.Inhaler technique data and other patient characteristics were evaluated in adults drawn from 2 studies conducted at the University of Pennsylvania. Subjects were from low-income Philadelphia neighborhoods and had uncontrolled asthma. Baseline characteristics were collected. Inhaler technique was rated by research coordinators who were trained with written materials.In 584 adults, 56% of metered dose inhaler users and 64% of dry powder inhaler users had adequate visually assessed inhaler technique. Inhaler technique did not vary by reading comprehension or numeracy levels.In this group of patients with uncontrolled asthma, visually assessed inhaler technique was adequate in more than one-half. Although incorrect inhaler technique is generally common and must be routinely addressed, this study suggests that other factors that lead to poor control must be identified.
