Opportunistic optimization of inhaler technique in hospitalized adults with asthma: a two-phase educational study.

ABSTRACT

OBJECTIVE: To investigate effectiveness of two different educational methods to improve inhaler techniques in patients with prior diagnosis of asthma, hospitalized with a non-asthma-related diagnosis. METHODS: We undertook a real-world, opportunistic quality-improvement project. Inhaler technique in hospitalized patients with prior diagnosis of asthma was assessed in two cohorts over two 12-week cycles using a standardized device-specific proforma of seven-step inhaler technique, classed "good" if 6/7 steps achieved; "fair" if 5/7 compliant; "poor" for others. Baseline data was collected in both cycles. Cycle one involved face-to-face education by a healthcare professional; cycle two involved additional use of an electronic device to show device-specific videos (asthma.org.uk). In both cycles, patients were reassessed within two days for improvements and the two methods compared for effectiveness. RESULTS: During cycle one 32/40 patients were reassessed within 48 h; eight lost to follow-up. During cycle two 38/40 patients were reassessed within 48 h; two lost to follow-up During cycle one, two and 12 had good/fair baseline technique respectively, and 26 poor. Most commonly missed steps were no expiry check/not rinsing mouth after steroid use. On reassessment 17% patients improved from poor to fair/good. During cycle two, initial technique assessment identified 23 poor; 12 fair; five good. Post-videos, 35% of patients improved from poor to fair/good. Proportion of patients improving from poor to fair, or poor/fair to good increased in cycle two vs one (52.5% vs 33%). CONCLUSION: Visual instruction is associated with improved technique compared to verbal feedback. This is a user-friendly and cost-effective approach to patient education.
